This invention relates to a method of operating on a workpiece, for example to modify or prepare a surface topography of the workpiece or parent material in order to increase the degree of mechanical friction or the degree of mechanical interlock with respect to another material or body, or to create holes in the workpiece.
Various methods have been used to increase the surface roughness of materials which have been made relatively smooth by machining, polishing, forming against a flat mould and so forth. These roughening methods include surface deformation by mechanical means such as grooving or knurling, or chemical means such as etching.
Alternatively, material has been added to the parent material surface by means, for example, of arc welding with a consumable filler wire. In one example small drops of metal have been deposited onto a metal surface, utilising the consumable electrode gas metal arc (GMA) process in which the current is modulated such that molten drops are detached from the melting wire electrode in a discrete and regular manner. These drops serve as raised dimples on the otherwise relatively smooth parent material surface and have been used to reduce the tendency to slip between the parent and another body.
EP-A-0626228 describes a method of modifying the surface of a workpiece which is to be joined to another member comprises exposing a series of locations on the workpiece surface to a power beam whereby at each location workpiece material is melted and spaced laterally under the influence of the power beam and then allowed to solidify so as to form a cavity surrounded by an area of solidified material which is raised with respect to the adjacent workpiece surface and has a re-entrant profile.
In accordance with a first aspect of the invention, we provide a method of operating on a workpiece, the method comprising causing relative movement between the workpiece and a power beam in a traverse direction so as to expose a series of locations on the workpiece to the power beam; and at each location causing the power beam to move relative to the workpiece in a predetermined manner having a component transverse to the traverse direction, whereby at each location, workpiece material is melted and displaced by the power beam so as to form a cavity or hole.
The advanced texturing technique claimed here differs fundamentally from the previously known and applied method. In the advanced form, the power beam is specifically caused to move (manipulated) in a predetermined manner at each location, instead of being static. The power beam may be pulsed so as to expose each location, although preferably it is continuous. The typically relatively small, high frequency "secondary deflection" motions of the beam at each location have the effect of markedly altering the redistribution of the molten material generated at each location. In general the movement of the beam is predetermined by an initial step of selecting the desired movement.
The invention can be used to form cavities in the surface of the workpiece or to create holes, typically extending through the workpiece. The formation of a hole can be carried out with or without a backing substrate. Furthermore, when a cavity or hole is formed, preferably the step of causing the beam to move in the predetermined manner is performed after the cavity or hole has been formed. This enables the shape of the cavity or hole to be accurately determined. In many cases a manipulation step may also be used during the cavity/hole formation where the diameter of the cavity/hole exceeds that of the beam.
The secondary deflection is preferably at such a frequency that at least one complete pattern repeat (or at least direction reversal) is performed at each location, and preferably an integer number of repeats is carried out at each position. For 1000 holes per second in steel, a secondary frequency of approximately 1000 Hz, 2000 Hz or 3000 Hz is appropriate. In this case the cavities would be ˜0.5 mm in depth and width, on a 0.7 mm pitch. Higher secondary frequencies may be required with smaller diameter cavities, and the material properties also influence the optimum frequency.
The "secondary deflection" used may take various forms, including circular, linear, ellipsoidal and/or simple geometric figure shaped motions, each having at least a component in the direction transverse to the traverse direction. The secondary deflection may also be combined with other suitable variations of temporal and spatial beam power density distribution (e.g. pulsing of beam current and/or varying the beam focus position) to achieve the desired effect and allow finer control over the cavity or hole formation process.
In general, the duration of the beam's interaction is carefully controlled so that the secondary beam deflection is consistently applied at each location, i.e. the secondary and primary beam motions are correctly phased in relation to one another so that the texturing effect is reproducible and does not vary in a non-systematic fashion.
In the case of cavity formation, suitable raised portions or dimples with re-entrant profiles may be generated on the otherwise comparatively smooth material surface from the parent material by rapidly melting small localised regions by means of a (typically focussed) power beam such as an electron beam impinging on the parent material. The high power density beam is rapidly moved from point to point to produce a series of such raised dimples. By closely spacing the dimples a semi-continuous line or ridge can be produced. It is noted that the raised material comes from melting and displacing the molten material, thus leaving a small cavity in the parent. Some material may be lost by vaporisation under the high power density of the applied beam.
In use, when a workpiece provided with cavities is adhered to another member, both the cavity and the raised dimple can contribute to mechanical interlock.
The adhesion to textured surfaces of materials from the vapour phase is also modified and enhanced.
The re-entrant profile further increases the mechanical forces required to separate the parent from, or slide the parent over, another member.
The re-entrant profile is beneficial in retaining, for example, an adhesive, especially an adhesive which does not itself bond to the parent, or only bonds with a low strength. Alternatively the bond strength between a non-adherent material, e.g. a low friction polymer, and the parent material surface may be increased substantially by the interlocking nature of the re-entrant profile.
In addition, the processed surface is substantially cleaned and freed from any minor contamination by the action of the beam, this increasing the bond strength obtained with any subsequent adhesive bonding operation.
Where a series of closely spaced dimples form a semi-continuous ridge, this ridge preferably also has a re-entrant profile.
For the purposes of increasing the overall bond strength of an adhesive, it is also noted that the adhesive preferably also enters the cavity as well as the re-entrant surface on the dimple to increase its bonding shear strength.
Preferably the surface topography utilises the existing parent material so no additional material is deposited onto the parent. The technique of changing the surface topography relies on utilising the melting/vaporisation capability of a power beam or high power density heat source typically brought to a focus in the region of the work surface.
Preferably a portion of the movement in the predetermined manner causes an area adjacent the location to be heated. Such an area may surround the particular location or may constitute another location. The adjacent location may be heated either before or after the formation of the cavity or hole, so as to effect a pre-formation or post-formation heat treatment respectively. The workpiece surface in the adjacent region can be either heated to below or above its melting point.
The form of the predetermined movement at the location may be similar to that of the portion of the predetermined movement at the adjacent location. However, typically, these have a different form, for example, the portion of the predetermined movement may take a raster form. In another example the area surrounding a cavity is heated by a circular movement of the beam. Typically the heating portion of the predetermined movement occupies about 30% of the time spent by the beam at a location.
The heating of an adjacent location is advantageous in that it can be used to control the cooling rate of the material and in that it produces improved adhesion of molten material to the workpiece surface. Pre-heating also allows the achievement of better synchronisation between the beam movements in the traverse and transverse directions.
The locations are typically spaced such that the material displaced from adjacent locations is in contact. The timing of the beam movements is also preferably controlled such that the material from the adjacent locations remains molten and coalesces during such contact. This coalescence allows a greater range of shapes and sizes to be achieved in the re-entrant features as these features are dependent upon surface tension forces within the ejected material and the temperature (cooling rate). The secondary deflection of the beam is therefore used to control the ejection of material, whereas pre/post-heat treatments can be employed to control the cooling rate.
In the preferred example, the power beam comprises an electron beam. Typically, this will be generated in a conventional manner using a conventional electron gun, the beam being moved across the workpiece under computer control using a technique similar to that described in U.S. Pat. No. 5,151,571 incorporated herein by reference. Typically, the power and speed of movement of the beam is such that more than 500 cavities per second are formed, preferably up to 580 or more cavities per second. The relative speed of movement between the beam and the workpiece is typically up to 1 km/s while the transit time between cavities is typically {fraction (1/100)}th of the dwell time at each cavity. The peak power density of the electron beam is typically in the range 105-107 W/mm2.
Cavities have been made at a range of speeds and sizes. The slowest speed is well below 400/second and there is no practical upper limit to the speed—for example 10000/second can be achieved in some materials, and more than that is certainly possible.
The shape of the beam may be important and preferably the current in the beam annulus is at least half the current in the central portion, and more especially at least equal to the central current. Satisfactory results are obtained when the current in the annulus is twice or even three times the central current, depending on the parent material and type of dimple desired.
In other applications, other power beams could be used, for example a laser. With a laser, typically a slightly higher net energy is required per cavity in contrast to an electron beam, owing to the reduced coupling efficiency with the workpiece. Actual laser pulse durations may be shorter than with electron beams, and correspondingly the peak energy density may be slightly higher. Cavities of similar size can be produced at a rate of 20 per second using a 300W mean output pulsed CO2 laser, giving about 15 joules per cavity.
Potentially any size of cavity or hole can be produced, for example ranging from those with diameters/depths of the order of millimeters to less than 10 micrometers. The minimum diameter of each cavity/hole is determined by the beam diameter, whereas large diameters can be achieved using a large beam diameter and an appropriate secondary deflection. Typically, the holes or cavities have a maximum diameter of substantially 0.6 mm and a depth in the range 0.6-1 mm. In the preferred case, the cavity or hole pitch is about 1 mm.
The dimensions of each cavity or hole set out above will be reduced by the intrusion of remelted material producing a re-entrant feature.
In some cases, the cavities or holes can have a substantially similar form and can then be arranged in either a square or close-packed arrangement. However, cavities or holes of variable size may be produced allowing other patterns of cavities to be formed.
In some cases, textures containing re-entrant and non-re-entrant features could be combined with the production of through holes rather than blind holes. The distinction between this and the known art of EB drilling is in the reliance of the process on its controlled displacement of some or all of the melted material rather than on its complete removal as in classical EB drilling. The control and implementation of this process would be in the secondary beam deflection, to control the timing and extent of the beam's penetration through the material. Partial ejection of material following penetration would occur, using a volatile backing material in the normal way, followed by a controlled melting and displacement of peripheral material to give the edge profile desired.
Typically, the workpiece is any metal or other material which can be melted or vaporized by the power beam. An example is steel. Non-metals may also be processed even though they are not electrically conductive. For example, re-entrant features can be produced in ceramics such as quartz and alumina, glasses, polymers, and composites. The mechanism is the same, save in some polymers, in which more of the material is vaporised.
In accordance with a second aspect of the present invention, a method of joining a workpiece to another member comprises preparing a surface of the workpiece using a method according to the first aspect of the invention to form one or more cavities in the surface of the workpiece; and adhering another member to the prepared surface of the workpiece.
This method is useful in a number of applications. In particular, the other member can be any polymer or other material which can be successfully introduced by any combination of pressure, heat or chemical reaction into the cavities in a chosen substrate or workpiece. For example, the other member could comprise one of nylon, PTFE, PMMA, aluminium and its alloys, phenolic resins, and magnesium and its alloys.
Examples of important applications of the invention include adhering brake pads to metal brake pad backings; bonding low friction polymers to corrosion-resistant metals for manufacture of prosthetic devices, for example hip joints etc; bonding of rubber to steel or other metals, for example for manufacture of impact-absorbing buffers; and bonding of aluminium to steel or cast iron, for example for the manufacture of lightweight brake disks.
Some examples of methods according to the invention will now be described with reference to the accompanying drawings, in which:

FIG. 11b shows a raster pre-heat treatment of an adjacent location;
FIG. 11c shows a circular post-heat treatment of an adjacent location; and,
FIG. 11d shows a linear pre-heat treatment of a region between locations.
FIGS. 1a-1 h illustrate successive stages in the formation of a cavity with a re-entrant surface feature. At the start, an electron or laser beam 1 impinges on a substrate such as a steel workpiece 2. Subsequently (FIG. 1b) a vapour filled cavity 3 begins to form with molten material 4 being displaced laterally outwardly. After further exposure, more molten material 4 is displaced and the beam is deflected to form an extended molten zone 5 at the surface (FIG. 1c). The beam 1 is further deflected (FIG. 1d) thus displacing further molten material 4 to form an extended molten zone at the surface.
The deflection can take a variety of forms as shown in FIGS. 1e and 1 f. Typically, it follows a closed locus and may be repeated a number of times.
The beam 1 then moves to a second location and begins to form a second cavity 3′ (FIG. 1g) thus displacing further molten material 4′. This further molten material 4′ overlaps with the previous material in an adjacent zone 5 and then subsequently solidifies into a quasi-spherical profile under the forces of surface tension as indicated at 6 in FIG. 1h thus forming the re-entrant feature 7.
In general, each cavity will have a similar shape and form and the cavities may be arranged as shown in FIGS. 2A (square) or 2B (close-packed). However, it is not essential for the cavities to be the same size and, as shown in FIG. 2C, a variety of different sizes allow a higher pattern density to be achieved.
Typical parameters for the electron beam are as follows:
For texturing of steel, with a beam of 140 kV acceleration potential, and 42 mA beam current, giving a power of ˜5.8 kW, the beam would be focussed to a diameter of ˜0.4 mm and would make ˜580 holes/sec in the workpiece. Examples of suitable deflection frequencies are set out above. In this case, the peak beam power density would be in the region of 105-107W/mm2. Each hole would be made with ˜10 joules energy, in ˜1.7 ms. The transit time of the beam from one hole position to the next is typically {fraction (1/100)}th of the dwell time at the hole position, i.e. in this case ˜17 μs. Since the beam may be travelling at speeds of ˜1 km/s over the workpiece surface, it need not be switched off or reduced in power whilst in transit, as no surface melting or other damage is likely at these scanning speeds in any event.
In steel, cavities produced with 10 joules are ˜0.6 mm depth below the original surface. These dimensions are reduced in each cavity by the intrusion of re-melted material, so giving the re-entrant features. The pitch of the cavities would typically be ˜1 mm.
Similar cavities may be produced with lasers; typically a slightly higher net energy is required per cavity, owing to the reduced coupling efficiency with the substrate. Actual laser pulse durations may be shorter than with electron beam, and correspondingly the peak energy density may be slightly higher. Cavities of similar size can be produced at a rate of 20 per second using a 300W mean output pulsed CO2 laser, giving ˜15 joules per cavity.
In the preferred example, the power distribution across the electron beam 1 has a form similar to that shown in FIG. 3 which is based on a 5 kw electron beam. Thus, there is a relatively high peak power density at the centre with a diameter of about 0.6 mm but a significant fringe power region. The width of the beam at half maximum is 0.25-0.3 mm.
In the case of an electron beam, many different types of electron beam guns could be used to generate the beam. In a typical electron gun, a cathode of refractory metal is heated to ˜2000� C. in a vacuum of 10−5 to 10−6 mbar. A potential of 30-150 kV accelerates the beam through a hollow anode. In a triode gun, the beam current is controlled by a third "bias" or "Welnhelt" electrode. In a diode gun, the beam current is controlled by the temperature of the cathode alone.
The beam passes through a system of magnetic lenses etc. which may incorporate a magnetic trap (a device that can protect the gun from the ingress of unwanted material), and deflection coils which can manipulate the beam at high speed. The working environment of beam may be a vacuum of as little at 10−1 mbar, typically 5�10−3 mbar. The vacuum level has an effect on beam quality and intensity.
Cathodes can be either directly heated or indirectly heated. Directly heated cathodes require replacement at intervals of (say) 10-100 hours, an operation which takes (typically) ˜15 minutes to accomplish. Indirectly heated cathodes are far more long lived, typically operating for hundreds of hours before requiring replacement.
Beam quality can be monitored in real-time by use of (say) a slit probe device. This has the potential to be linked to the electron beam control systems as an automatic system.
In one example, the workpiece can be processed as a continuous strip using a conventional air-to-vacuum-to-air system which has been successfully built for applications such as the manufacture of saw blades, in bimetal strips etc.
An alternative approach is to process reels of strip material individually (FIG. 4), so that the blank material 10, on a reel 11, is loaded into a specially designed vacuum chamber 12, together with an empty take-up reel 13. These reels 11,13 would necessarily be quite large in diameter if the material is not to take a "set". For example, the minimum pure bend radius to give 0.2% strain in 7 mm thickness material is 1750 mm. A reel with a radius of 2.5 m would therefore be able to hold up to 6 tonnes of 80 mm wide strip—a length of 1.4 km. With a 5 kW gun 14, a lm/min processing speed is possible, meaning that such a reel would take about 24 hours to process. However, if texturing speed is increased proportionately to gun power the with a 50 kW gun, processing at 10 m/min, such a reel would be processed in ˜2� hours.
A preferred route, however, from the point of view of integrating the electron texturing technique with existing production practice, would be to texture individual workpieces such as brake pad backing plates (PBP). An example of apparatus for achieving this is shown in FIGS. 5 and 6. Two chutes 20, 21 are mounted side by side (only one shown in FIG. 6) and two stacks of PBPs are fed down the chutes towards an electron gun column 22 such that both lie within a deflection field. The outlets of the chutes 20, 21 are located in an evacuated chamber 23. Whilst one PBP is being removed after processing, the other is being processed. This means that the available beam power can be utilised fully by being operated continuously. In addition, unlike other techniques, this would readily enable each PBP to be selectively textured only when it is required. Texturing selected areas of conventional PBPs with holes in already would also be possible.
In practice, stacks of PBPs could be loaded continuously into each chute so that the chute's sidewalls act as an effective vacuum seal. To facilitate this, every 100th PBP or so could be a blank dummy, exactly fitting the chute dimensions perhaps with the assistance of an "0" ring to maintain a vacuum seal. Air exits from the chutes as shown at 25, 26 are provided to maintain vacuum, the exits being connected to a vacuum pump (not shown).
After texturing, the PBPs could simply fall into a hopper 27 which would be emptied at regular intervals.
Once a workpiece with a prepared surface has been formed, it can then be joined using adhesive to another member in a conventional manner. As previously explained, the textured surface will considerably enhance and strengthen the joint and indeed will enable certain materials to be joined using adhesive which previously could not be joined.
The examples described so far illustrate the formation of blind holes or cavities in the surface of the workpiece. The invention can also be used to form through holes.
FIG. 7 illustrates the formation of an asymmetric penetrating hole 30 in a workpiece 32.
FIG. 8 illustrates in more detail the formation of a through hole in a workpiece 34. Initially, an electron or laser beam 36 is focussed onto a surface 38 of the workpiece 34 so as to penetrate the substrate and start to enter the backing material (FIG. 8a). Optionally, the beam 36 can be deflected at very high frequency so as to "shape" the beam for non-circular, non-beam-shaped holes. As the beam 36 penetrates the workpiece 34, a region of liquid metal/substrate 40 is formed along the sides of the hole.
As soon as the beam impacts on the backing substrate 42 (typically made of silicon rubber or other volatile material), a small gas explosion will occur which causes most or nearly all molten material 40 to be ejected leaving sharp edges to the hole. (FIG. 8b).
The beam 36 is then deflected at a lower frequency (FIG. 8c) to melt the hole periphery and to displace new/existing melted material 44 in a controlled fashion. Further vapour from the backing substrate 42 assists the metal/substrate flow if required.
Adjacent holes can be formed in a similar manner (FIG. 8d) to create overlapping molten zones 46 so as to produce curved re-entrant or other shaped holes.
Alternatively, asymmetric molten zones 48 (FIG. 8e) can be formed which can be either overlapped or not as required. The hole asymmetry is generated via controlled beam deflection.
FIG. 9 illustrates the formation of a through hole without the use of a backing layer. Thus, in FIG. 9a a beam 36 impinges on a workpiece 34 to form a hole 50 with molten material 40 along its sides. The beam 36 will be deflected at very high frequency so as to "shape" the hole.
The beam is then deflected at an intermediate frequency (FIG. 9b) to extend, shape and displace molten material 40 at a peripheral zone 52.
Further, non-overlapping symmetric re-entrant holes could be formed in a similar manner (FIG. 9c) or alternatively the holes could be located close to one another so as to generate overlapping, molten regions 54 defining reentrant features. In a further alternative (FIG. 9e) non-overlapping asymmetric holes can be produced.
In the examples shown in FIGS. 8 and 9 hole formation could be carried out at rates of about 1000 per second. The initial deflection frequency (FIGS. 8a and 9 a) will typically be in the range 100 KHz-2 MHz while the subsequent "profile" shaping deflection frequency used at the stages shown in FIGS. 8b and 9 b will be in the order of 1 KHz-100 KHz.
In some cases, the electron or laser beam 1 can be used to preheat areas prior to texturing/perforation and typically being defocussed. Thus, the beam can be time shared between these tasks allowing both to be carried out substantially simultaneously.
FIG. 10 shows how a series of cavities can be formed in a workpiece by the summation of a number of movements of the beam. The arrow 100 denotes the relative movement of the workpiece with respect to the electron gun.
The beam traverses the workpiece between a number of locations along a substantially linear path. This traverse direction or "primary deflection" is shown by the arrows 101. This traverse is repeated throughout the operation, as indicated by the arrow 102. The curved arrow 103 indicates the orbital motion (secondary deflection) of the beam which, when applied, causes the cavities to have the desired form.
It should be remembered that the travel time between locations is typically about {fraction (1/100)} of the time spent at each location and therefore the movements indicated at 101 are much more rapid than the relative motion of the workpiece 100, or the orbital secondary deflections 103.
By summing the three movements mentioned above and with appropriate control of their relative frequencies, a combined motion of the beam in relation to the workpiece, generally indicated at 104 in FIG. 10, is generated.
FIGS. 11a-11 d, show the use of various secondary deflections in pre/post-heat treatments. In FIG. 11a, a loop pre-heat is shown in which, prior to cavity formation, the beam firstly follows a circle 105, the circle lying outside the circumference of the final cavity. The beam is then moved in two circles 106, 107 of smaller diameter to actually form the cavity.
FIG. 11b shows a raster preheat where part of an adjacent location (for later cavity formation) is first pre-heated with a raster movement 108. The cavity at the actual location is then formed using a circular beam path at 109. The remaining part of the adjacent location is then pre-heated with a further raster movement at step 110.
As the beam movements are very rapid, the series of locations in the line next to those currently experiencing cavity or hole formation can therefore be pre-heat treated. The high speed of the process results in little loss of pre-heat temperature by the time that the respective cavity/hole is formed after pre-heat treatment.
FIG. 11c shows a suitable secondary deflection for a loop post-heat treatment. The circles 111, 112 denote beam movements for first forming a cavity, after which the beam is deflected so as to follow a circular path 113 in another location where a cavity was formed earlier.
FIG. 11d shows a further example of a pre-heat treatment which is particularly beneficial for the formation of large agglomerations of ejected material. The beam is firstly moved in a line 114 towards a location in which a cavity is to be formed. This line extends for most of the distance from the lines of adjacent locations defining the previous primary beam deflection path. The surface of the workpiece is melted in the vicinity of the line.
The beam then follows a circular path 115 to effect the formation of the cavity. When this is performed at a suitable speed the ejected material from the previously formed line of cavities remains molten. The ejected material from groups of cavities therefore coalesces by surface tension forces to create large features in the interstices between the cavities.
Some further example conditions for forming cavities using an electron beam are shown in the table below.

Share My Cock Allyssa Hall
Allysa Hall likes to get involved with her guys and she also likes to share her cock with her friends. That's very noble of her isn't it? This movie clip shows just how kind natured the girl is and how willing she is to share because just when she has that lovely cock between her tits just where she wants it her friend wants a piece of the action too. But being a good girl helps her to overcome er selfishness and hand over the cock to another. I don't think that the guy could really give a flying fuck who has his cock to be honest!

Yes, if you have a business, you should have a website. Period. No question. Without a doubt. The key to making the most of the web is making your business as accessible as possible, letting people interact with you in a way that they like, whenever they want to. Your customers are online 24/7/365, and as such they expect to be able to interact with businesses and organizations whenever and wherever they are online. At the most fundamental level, this means a basic, professional looking website with easy to find, relevant information about your business. At a more advanced level, that could be a fully-blown ecommerce website that lets customers buy your products or services, essentially giving your businesses a 24/7/365 storefront. In fact this website was built with Drupal and a free theme!
We utilize three different Content Management Systems to create a stunning website in less than a week. With thousands of site themes and useful modules that expand the sites capabilities to choose from. The best part is that we can teach you how to access your website 24/7/365 from anywhere and you can update the content and images. Also, by combining services and allowing us to create a brand and theme for your business, we then can replicate the theme on all platforms for maximum customer recognition. Come join us today and make an impact on the internet.
Drupal is an open source content management platform powering millions of websites and applications. It's built, used, and supported by an active and diverse community of people around the world. Why choose Drupal? Use Drupal to build everything from personal blogs to enterprise applications. Thousands of add-on modules and designs let you build any site you can imagine.
WordPress has been incredibly successful and risen from a handful of users to the most-used blog tool in its category. Start a blog or build a full-fledged website. The only limit is your imagination. A blog is a type of website that shows that newest content at the top of the page. A blog can also be one part of a website with multiple pages. Wordpress is the leader in this category.
Joomla is an award-winning content management system (CMS), which enables you to build websites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an open source solution that is freely available to everyone.
What's a content management system (CMS)?
A content management system is software that keeps track of every piece of content on your Web site, much like your local public library keeps track of books and stores them. Content can be simple text, photos, music, video, documents, or just about anything you can think of. A major advantage of using a CMS is that it requires almost no technical skill or knowledge to manage. Since the CMS manages all your content, you don't have to.

It's Sunday. Another class in which I am tutoring.

It's sort of like a 'social or voluntary work' for me. But I do enjoy it.
No free time for me on Sundays morning.
But, sure I could spend a great Sunday afternoon afterwards.

Discussion in 'XenForo Questions and Support' started by ChemicalKicks, Sep 9, 2011.
So the obvious question what would you recommend adding to the config to enable caching?
We're using memcached here.
It's a shame those of us without caching won't be able to utilise it.
That'll teach us to be tight gits and use shared hosting
Why don't you use a filecache? No additional software to be installed only requires some permission changes... ok not the best but better than no cache at all!
You can use the file cache on shared hosting
Ah thanks guys, I'll look into that.
I'll speak to the host and see if it's possible.
You shouldn't need to talk to your host about this.
I had file caching on my old vb4 set-up I'm wondering what I specifically have to add to the config to turn it on though
Nothing to really talk to your host about, just edit your config file with the correct options and chmod the filecache folders that is unless you are on a 100% managed server
What do we need to add to the config!!
$config['cache']['enabled'] = true;$config['cache']['backend'] = 'File';$config['cache']['backendOptions'] = array('cache_dir' => '{{FULL PATH TO CACHE DIR}}');$config['cache']['frontend'] = 'Core';$config['cache']['frontendOptions'] = array('caching' => true, 'automatic_serialization' => true, 'lifetime' => 1800);
Replacing the {{FULL PATH TO CACHE DIR}} To the full path to your cache dir, recomended is /library/cache
$config['cache']['enabled'] = true;$config['cache']['backend'] = 'File';$config['cache']['backendOptions'] = array('cache_dir' => '{{FULL PATH TO CACHE DIR}}');$config['cache']['frontend'] = 'Core';$config['cache']['frontendOptions'] = array('caching' => true, 'automatic_serialization' => true, 'lifetime' => 1800);
Cheers Cezz,
Couple of things, once I create the directory and add this to the config will it the directory start to populate with the caching stuff? I'm confused to how this works, with vBulletin I added a line to the config but it appeared to create the directory all by itself.
When you say full path to the cache would "/library/cache" be enough?
No it would need to be the FULL path I believe eg... /home/user/www/xenforo/library/cache or /www/var/user1/site1/library/cache
Honestly I am not 100% how it works but I think you need to create the folder and chmod it corrently and then yeah it starts to fill up with the required files.
FWIW, I'd recommend internal_data/cache, for ease of use.
Awesome thanks for the tips.
Thanks guys.
Surprised it has to be an absolute full path rather than relative.
I might be wrong about that mind you, either way I would use an absolute path so I know exactly where the cache is going as it could even be outside of your public_html folder if you wanted for some reason!
Just tested it on my local and it works fine
You need to manually create the internal_data/cache directory otherwise you get an exception thrown.
Thanks again guys.
I noticed there is an empty internal_data/page_cache folder -- is that one for something else?
It's for something else in the future...
Hey Brogan,
Glad you got it working.
I got an exception and I created the folder What path format you using I tried the auld /home/user/public/ETC but that threw up an exception with this in the error.
"/var/sites/t/the-sps.org/public_html/library/config.php" so should I be using somthing like the following....
"/var/sites/t/the-sps.org/public_html/internal_data/cache" should I have a / on the end of that?
Separate names with a comma.

Beyond Diet and Exercise: Controlling Blood Sugar
According to the recently published National Diabetes Report, over 29 million people in the United States have diabetes. That's nearly 10% of the population. Perhaps more disconcerting is that nearly 30% of those folks go undiagnosed, unaware that they even have the disease. All told, adult type 2 diabetes accounts for 95% of all diagnosed cases of diabetes.

Zesty Tofu, Avocado, And Quinoa Salad
Adapted from a Prevention magazine recipe, comes a salad that is as simple as it is tasty and healthy. It features quinoa, a grain that is not only full of fiber, but also loaded with plant-based protein. But, the starring role of this salad goes to the luscious avocado that sometimes gets a bad rap for its high fat content. However, this seemingly decadent fruit is actually high in monounsaturated fat that helps increase good HDL cholesterol.
5 Great Longevity Tips
What are the secrets to a long life and healthy aging? And how can you kick those common aging laments to the curb? Juvenon provides an essential foundation for cellular health and in turn renewed energy and vitality.
The Newest Theory of Aging: Inflammaging
Cracking the code on aging remains one of the biggest challenges in science today. As recently as a decade ago, the general aging theory focused on the oxidative stress model. Basically, the idea was that aging is due to the sustained accumulation of cellular damage and a lifetime of reactive oxygen species and free radicals coursing through our veins.
Are Doctors Wrong About CoQ10?
According to U.S. News and Report, Coenzyme Q10 (or CoQ10 for short) is the third most popular supplement in the United States. CoQ10 supplementation is prescribed by many doctors for treating or preventing a range of conditions from headache relief to Parkinson's disease.
Fasting, Starvation and Caloric Restriction
Recently, conflicting information has emerged on the topic of fasting, starvation and weight gain. On the one hand, there is the 'starvation myth' based on the theory that starving oneself to lose weight can cause weight gain. However, on the other hand, there is now compelling new research showing the beneficial effects of caloric restriction, e.g., weight loss, decreased oxidative stress, inflammation, and increased longevity.
Obesity: Examining the Role of the Mitochondria
In last month's Juvenon Health Journal, we discussed a recent study conducted by the Harvard School of Public Health that identified the top preventable risk factors for premature mortality. Smoking tops Harvard's list of preventable risk factors with high blood pressure and obesity closely following.
Dietary Restriction: Getting More From Your Mitochondria
Cutting down caloric intake, or dietary restriction (DR), seems to produce benefits – i.e., a healthier, longer life – that are almost too good to be true.
"Balanced" Diet: Fine-Tuning for a Longer Lifespan
Is it possible to extend lifespan? Although it hasn't been proven for humans yet, the answer seems to be yes, at least for yeast, flies, mice and, according to recent research, primates.

Your true biological age is determined not by years but by the state of your body's structure and functions.
There are two remarkable benefits that healthy aging offers:
First: don't get sick as you age.
Second: restore your health and eliminate your health concerns
The key to healthy aging is a robust energy metabolism which supplies cellular fuel you use to maintain your health.

Shlock Appeal // Robot Jox
June 22nd, 2016 | Film | 0 Comments
Considering how much people love the idea of giant robots fighting, of course Pacific Rim couldn't be the first movie to show that on film. I don't know if Robot Jox was the first, but it's the kind of movie that simply had to exist: an 80s/90s B-movie with bad acting and cheap special effects in which giant robots (or mechs, really, since they have human pilots like in Pacific Rim) fight each other. Even better: America beats the Soviet Union. And thankfully it was directed by B-movie master Stuart Gordon (Re-Animator, From Beyond).
The plot is that in the future there are no more wars – when countries have a dispute, they send in their best mech pilots to fight each other and whoever wins wins. America has this pilot Achilles (Gary Graham) who's a real hot shot. He has to fight the Ruski's hot shot Alexander (Paul Koslo) to decide who gets Alaska. There's also a girl involved named Athena (Anne-Marie Johnson) who's a real bad-ass. The love story between Achilles and Athena is kind of lame, but the heart of the movie is the frenemy bromance between Achilles and Alexander. Forgetting all that though, the reason to watch this is for the cheese factor and fairly impressive non-CGI robot fighting. And Robot Jox has plenty of both.

Cornell basketball team ready to rebuild
ITHACA, N.Y. -- A Big Red run into the Sweet Sixteen last spring and three straight Ivy League titles has set the bar pretty high in Ithaca.
The Big Red will need new faces to take some big steps in order to win the Ivy again this year. The most obvious new face at Newman Arena is that of new head coach Bill Courtney, but he's not the only one.
Courtney replaces former coach Steve Donahue and will be tasked with replacing four starters from last year's Sweet Sixteen squad. Senior guard Chris Wroblewski is the only starter back from last year's Ivy League champs.
"There's gonna be some bumps in the road maybe this year, but as a young team, we're going to have to know that it's not what happens, it's how we respond to it. There is going to be adversity, but with young players, we are going to be resilient and we'll come back and be ready to work harder," Wroblewski said.
"None of these guys have really played an extended amount of time before and especially without Chris, who played a lot of minutes last year. It's been a challenge at practice," Courtney said. "He was out a bit with a broken nose and now with the ankle, so we've had to get used to playing without him. I think it may end up being a blessing in disguise for some of the guys who haven't played before to get an opportunity to go out and see what they can do."
As in previous years, Cornell's hopes to win another Ivy League title will ride largely on their ability to step up and knock down the three point shot.
"We're gonna shoot a lot of threes and I think that's good because we have shooters who are capable of doing that, we're probably going to play an up tempo brand of basketball and it's going to be a lot of fun," said Wroblewski.
"The team's been built that way. To be a good perimeter shooting team. We also hope we find some balance and get some inside scoring and some drives to the basket, but yes, the three point shot will be a weapon," Courtney said
Cornell is well aware they are missing last year's big man, Jeff Foote, but hope to come up big on defense as a team to make up for it.
"We'd love to have a seven footer, but most programs across the country don't have seven foot guys that are as good as Jeff Foote, so everyone has to make that adjustment without playing with a guy who can erase mistakes on the defensive end, so we have to do that much better individually on defense," Courtney said.
"We're gonna have to play extra tough and extra hard on the defensive side. We don't have Foote, we don't have a seven footer in there so we have to front the post and be extra aggressive on defense," senior forward Aaron Osgood said.
If the Big Red can get big time performances from new players, stay hot at the three point line and make stops as a team on defense, then a fourth straight Ivy League title could be theirs.
- From the Troy Record, "[Albany coach, Will ] Brown said the team will play a little different defensively, packing it in more and he said two keys to beating Cornell were defending the 3-pointer and making sure they get a shot up every time down the floor."
- Rush The Court writes of the Big Red's weekend games:
Cornell at Albany, 7:30 PM – While the Great Danes should be improved with Tim Ambrose returning for his senior season, most of the college basketball world will be focused on the Big Red, who lost eight seniors, including Ryan Whitman, Louis Dale, and Jeff Foote along with their coach Steve Donahue, who headed to Boston College. New coach Bill Courtney will be relying on Chris Wroblewski as one of the few known elements of his team to help guide the Big Red in the early season while they try to establish a new identity.
Cornell at Seton Hall, Noon on The Big East Network and ESPN Full Court – Their second game of the weekend should be significantly more challenging for the Big Red as they travel to play a Pirate team that has a new coach in Kevin Willard and returns two stars in Jeremy Hazell and Herb Pope. We know what to expect from Hazell (shooting, lots of shooting), but we aren't sure what to expect from Pope who underwent cardiac surgery in the off-season to repair a congenital abnormality. Pope looked pretty good in some exhibition games, but we expect it will be a while before he gets back to the level where he was last year. A year ago, the Pirates won a tight game over the Big Red on the road. Don't expect this year to be as close.
- The Albany Times Union gives an update on Albany's rotation when the Danes meet Cornell on Friday night.
- Previewing tonight's game, the Times Union writes:
...Cornell, which got to the Sweet 16 of the NCAA Tournament last year, lost eight seniors to graduation, including Ryan Wittman, who left as the school's all-time leading scorer. Also gone is coach Steve Donahue, who is now at Boston College.
Bill Courtney, the new coach, said he doesn't know if the top returning player from last year, 6-0 guard Chris Wroblewski (8.9 ppg), will be able to play because of an ankle injury.
"I don't know," Courtney said. "It will be a decision we'll make near game time. We're young. We have guys who played spot minutes last year and guys who didn't play at all who are going to have to step up."
- From the Troy Record:
The Big Red lost their three leading scorers from a season ago, who all averaged in double figures. "I know they lost a lot of good players," said [Albany] sophomore guard Logan Aronhalt. "That usually means there are a lot of good players coming up behind them."
- Jonah Hecht of WVBR tells you "what to watch for" on Friday when Cornell faces Albany. He writes:
"Perhaps it's appropriate that the Cornell Men's Basketball Team opens its season on the day after Veterans' Day, as this will be the season after a veteran season. Much has been said of the team's loss of 8 seniors, as well as longtime coach Steve Donahue. The Red are going to be a work in progress during the non-conference schedule, as new players get used to playing with each other and for a new coach. The team ought to look much better come the start of Ivy play, but here are three things to look for tomorrow night in determining if this team has a shot at winning a fourth straight Ivy crown.
Defense: Often overlooked was how good Cornell's defense was last season. Coach Bill Courtney has emphasized playing aggressive defense, and with an undersized team, playing consistently on the defensive end will be critical for this young roster.
Points in the paint: Last season's team relied on center Jeff Foote when it absolutely needed a basket. This season the Red boast no player taller than 6'9". Besides, several of their big men either prefer to play on the perimeter, or have limited offensive games. The team is going to need the threat of a post scorer, though, to keep opposing defenses honest.
Rebounding: Albany lacks size, so if Cornell struggles on the glass, it could portend a long season."
The Gazette of Massachusetts writes, "FORMER PLAYERS - There will be quite a few former Minutemen who'll be in uniform for other schools around the country. Max Groebe, Jr., Cornell - Groebe could finally get consistent minutes after being buried on the deep Big Red squad last year. He's a candidate to start at shooting guard."
- SlamOnline writes, "[Temple's] disappointing loss to Cornell that ended their season in the first round of the NCAA Tournament also marked the end for their leading scorer Ryan Brooks."
- Temple has not forgotten about Cornell writes Philadelphia Sports Daily:
Temple Hoops Season Preview: Remember Cornell
The Temple Owls are reminded of it every time they walk into their locker room at Liacouras Center.
Cornell 78, Temple 65.
It's written on the stat books that Fran Dunphy still has in the room – reminding his players of their first-round NCAA tournament upset at the hands of 12th-seeded Cornell.
"It's kinda like a constant reminder that we don't want that to happen this year," guard T.J. DiLeo said. "We don't want that to be us. We wanna get back into that position where we're competing in the NCAA tournament, but we wanna remember that game. We don't want that to be our fate this year."
That's where it begins for the Owls. It's been almost eight months since that defeat in Jacksonville, Fla., Temple's third straight first-round exit. And as much as players usually talk about moving forward, this one is still on their minds.
"Certainly the last game we played was Cornell, and Cornell beat us up pretty good. I hope they remember that going into Friday's game," Dunphy said. "If we're fortunate enough to get back to the NCAA tournament, I'm sure we will learn some lessons from that."
Friday's game is the first chance to get some retribution for that deflating defeat – the season opener at Liacouras Center against Seton Hall. No, it doesn't have the weight of an NCAA tournament game, but think of it as another step on Temple's road to recovery.
Because that loss will serve as the enduring moment of last year's Owls – even after they won 29 games and a third straight Atlantic 10 championship.
"We really don't know what the problem was," projected starting forward Scootie Randall said. "That loss, it really hurt us and it pushed us to work hard over the summer and have a better year this year. For us to go back in there and see that Cornell book every time, it's depressing, but we gotta look past it and have a better year this year."
Of course Dunphy and his team won't dwell all season on a game that won't have an immediate impact on this season, but it is a long time until the Owls get a chance to avenge it and succeed in the goal of actually winning an NCAA tournament game.
Until then, getting back onto the court for games that count is a nice first step to getting over Cornell.
"I don't think it will affect us, but it's never forgotten," guard Juan Fernandez said. "We definitely wanna get there again and we definitely wanna make a run in the tournament, but to get there we gotta start thinking about Friday and then go one game at a time. That's the only way."
- The Columbia Spectator notes, "[Columbia had a] 0-3 start to league play. [a year ago]. All three losses were of the blowout variety, and the first two came against Cornell, which went on to win the league and shock the country by reaching the Sweet 16 round of the NCAA Championships."
- The Minnesota blog, From the Barn writes, "Cornell had a magical run last year. This year they'll be lucky to be play in any post-season tournament"
- The Pioneer Press projects that injured Minnesota star, Devoe Joseph, is expect to return from his injury for the Cornell game on December 4.
- The Milwaukee Journal-Sentinel writes, " I once thought the Atlanta Falcons' run of 42 years without back-to-back winning seasons was the most remarkable streak in sports. But it's not. Northwestern has never been to the NCAA Tournament. Ever. How does that happen, when all it takes is two pretty good players? Academics aren't an excuse. They do it at Duke, Stanford and, um, Cornell. Northwestern has a beautiful campus, a marginally nicer gym than Cameron Indoor and a primo location. How can it possibly lose?"
- The Montgomery Advertiser notes, "Alabama has lost two straight sea son openers to Mercer two years ago and Cornell last season."
- Previewing Boston University, the Boston Globe writes, "[The Terriers have] tough nonconference games against four Atlantic-10 opponents, Cornell Nov. 27, and at Kentucky Nov. 30."
- Cincinnati.com writes, "Goodbye Ivy League, hello ACC. Steve Donahue parlayed a Sweet 16 trip with Cornell into the Boston College job."
- The Richmond Times Dispatch writes of the ACC's new coaches, "[Steve] Donahue is the sexiest hire. He led Cornell to three consecutive Ivy League titles, a 28-4 conference record during that span, and was a major name for job openings after the Big Red made the NCAA tournament's Sweet 16 as a No. 12 seed last season."
- SBNation.com notes, "[Donahue] finally got a chance to shine as a head coach at Cornell in 2000, and compiled a 146-138 record at Cornell. Donahue struggled early in his Cornell career, but took the Big Red to new heights in the final three years. Cornell posted an impressive 72-21 record since the start of the 2007-08 season. The Big Red finished first in the Ivy League each of the last three seasons and made appearances in the NCAA tournament. Donahue's Cornell career was highlighted by a 29-5 record and an appearance in the Sweet 16 round of the NCAA tournament."
- Below an excerpt from the Boston Globe:
[Steve Donahue said,] "Our teams at Cornell shot a high percentage, but I don't think we ranked in the top 100 in attempts in the country." Donahue has converted the Eagles to the up-tempo style of offense he used in guiding Cornell to a 29-5 record last season... Donahue noted that two years ago, Cornell had four players with 70-plus assists.
- The Boston Herald writes:
After a few subpar seasons recently, [Boston College] athletic director Gene DeFilippo fired [Al] Skinner and tabbed Steve Donahue as his replacement. Donahue spent the last 10 seasons at Cornell, culminating in a run to the Sweet 16 last March.
Donahue (left) had been a hot name in coaching circles for the past few seasons, but said he would only leave Cornell for a "home run" job. Clearly, BC fit the bill.
- From the Boston Herald:
There are no Ivy League championship plaques hanging on the walls in Steve Donahue's new office. There are no newspaper clippings about his success in 10 years at Cornell. Not even the Sports Illustrated photo from last March, which featured three Big Red players diving for a loose ball during the NCAA tournament, holds a spot on the wall.
All of those memories have been tucked away by Donahue as he sets out to create a new legacy at Boston College.
"I made a point of never mentioning Cornell," Donahue said. "I never have anything in my office that's Cornell related. I think it's not fair for (the BC players). It's just another part of my journey here. This is all new."
About the only thing Donahue has brought from Cornell is a library of tape to allow his new players to learn schemes that are a major departure from the plodding style of previous coach Al Skinner.
While players have checked out the tapes in their free time, they already had impresssions of Donahue when he was hired last April on the heels of an impressive run to the Sweet 16.
"I knew that he had a really good career at Cornell and brought his team to the Sweet 16," senior forward Joe Trapani said. "That's obviously something I'd love to do -- make it back to the tournament again."
Though Donahue has downplayed his success at Cornell, he's aware his time in the national spotlight added credibility with his new players.
"I would say that the run we made at Cornell had a lot to do with their trusting what I was saying," Donahue said. "I'd be foolish to think that my word would be what they would just believe. Seeing what we did at Cornell has definitely been a help in terms of getting these guys to believe in what we're doing."
Donahue understands that credibility only extends so far. The Eagles open their season tonight at home against St. Francis (N.Y.). If they lose tonight or experience a rough patch during the season, the furthest thing from the BC players' minds will be Donahue's success at Cornell...
- Blogging The Bracket thanks The Cornell Basketball Blog for a reminder of the name of the DirecTV Great Eight Tournament. BTB suggested Cornell could be a participant if the Tournament were brought back.
- MadduxSports.com writes, "The [Kentucky Wildcats] went to the Big Dance where they hammered opponents, beating East Tennessee State 100-71 Wake Forest 90-60 and Cornell 62-45. In the Elite Eight, Kentucky lost to West Virginia 73-66. It was a good but disappointing run for the Wildcats and their new coach John Calipari."
- From the Daily Pennsylvanian:
