Home > Press > Brown Chemists Create More Efficient Palladium Fuel Cell Catalysts
|A platinum alternative Brown researchers have found a way to create a larger active surface area with palladium nanoparticles to catalyze energy-producing reactions in a fuel cell.
Two Brown University chemists have overcome a challenge to fuel cell reactions using palladium catalysts. The scientists produced palladium nanoparticles with about 40 percent greater active surface area than commercially available palladium particles, and the nanoparticles remain intact four times longer. Results appear in the online edition of the Journal of the American Chemical Society.
Even small devices need power, and much of that juice comes from fuel cells. As these devices become even smaller, the rush is on to find more efficient ways to power them.
In the last several years, scientists have discovered that palladium, a metal, is a strong candidate for providing that initial boost that helps fuel cells go. Palladium is far cheaper than another popular fuel cell catalyst, platinum, and it's more abundant.
But researchers have wrestled with creating palladium nanoparticles with enough active surface area to make catalysis efficient in fuel cells while preventing particles from clumping together during the chemical processes that convert a fuel source to electricity. Two Brown University chemists have found a way to overcome those challenges.
The scientists report in the online edition of the Journal of the American Chemical Society that they have produced palladium nanoparticles with about 40 percent greater surface area than commercially available palladium particles. The Brown catalysts also remain intact four times longer than what's currently available.
"This approach is very novel. It works," said Vismadeb Mazumder, a graduate student who joined chemistry professor Shouheng Sun on the paper. "It's two times as active, meaning you need half the energy to catalyze. And it's four times as stable."
Mazumder and Sun created palladium nanoparticles 4.5 nanometers in size. They attached the nanoparticles to a carbon platform at the anode end of a direct formic acid fuel cell. The researchers then did something new: They used weak binding amino ligands to keep the palladium nanoparticles separate and at the same size as they're attached to the carbon platform. By keeping the particles separate and uniform in size, they increased the available surface area on the platform and raised the efficiency of the fuel cell reaction.
"It just works better," Sun said.
What's also special about the ligands is that they can be "washed" from the carbon platform without jeopardizing the integrity of the separated palladium nanoparticles. This is an important step, Mazumder emphasized, because previous attempts to remove binding ingredients have caused the particles to lose their rigid sizes and clump together, which gums up the reaction.
The Brown team said in experiments lasting 12 hours, their catalysts lost 16 percent of its surface area, compared to a 64-percent loss in surface area in commercial catalysts.
"We managed to ebb the decay of our catalyst by our approach," said Mazumder, who is in his second year in Sun's lab. "We made high-quality palladium nanoparticles, put them efficiently on a support, then removed them from the stabilizers efficiently without distorting catalyst quality."
The Brown scientists now are looking at various palladium-based catalysts with enhanced activity and stability for future fuel cell applications.
"We want to make it cheaper with analogous activity," Mazumder said.
The research was funded by the Division of Materials Research of the National Science Foundation and a Brown seed fund.

The Trouble With Self-Esteem
Published: March 3, 2002
I was dismayed by the analysis of self-esteem in Thomas Szasz's letter (Feb. 17), commenting on Lauren Slater's article (Feb. 3). He wrote: ''As children mature, they may learn to do certain things better than their siblings, parents, teachers or other adults. That will give them self-esteem.'' Ouch! He suggests that self-esteem comes from besting the world. Climb up there, stay there or it's goodbye self-esteem. I may not do things better than most people, but I have plenty of self-esteem.

The Joint Information Systems Committee (JISC) has announced that it will fund a partnership between ProQuest CSA and Oxford University Library Services (OULS) to digitize more than 65,000 items from the Bodleian Library's John Johnson Collection of Printed Ephemera.
Housed in the Bodleian Library at Oxford University, the John Johnson Collection is a collection of printed ephemera, and one of the most significant single collection of ephemera in the UK. Containing 1.5 million items ranging in date from 1508-1939, it spans the entire range of printing and social history. It was assembled by John de Monins Johnson (1882-1956), printer to the University, who was visionary in his preservation of Britain's paper heritage. The project will make available rare or unique archival materials documenting various aspects of everyday life in Britain in the nineteenth century and before. The collection features posters and handbills for theatrical and non-theatrical entertainments, broadsides relating to murders and executions, book prospectuses, popular topographical prints, and different kinds of printed advertising material. The collection will form a resource for researchers interested in the histories of consumption, leisure, gender, popular, and commerce. As each item will be presented as a full-color facsimile, it will also be for researchers studying the development of printing and visual culture in the age of industrialization and mass advertising.
The project will make a selection of materials from the John Johnson Collection available throughout the UK. Investment by the JISC and OULS will cover the costs of digitization and cataloguing, including conservation costs associated with digitization, while ProQuest CSA will bear the cost of interface development and long-term sustainability. The online collection will consist of five different categories of material: nineteenth century entertainment material; booktrade material; popular prints; crime, murders, and executions; and advertising.

31 Claims.
This invention relates, generally, to rate and attitude indicating instruments and the invention has reference, more particularly, to a novel instrument especially adapted to provide navigational information such as the heading of a craft with respect to the meridian or other reference, the rate of turn of a craft, and the attitude of a craft about the fore and aft and transverse axes thereof.
Heretofore, it has been common to employ gyroscopic instruments such as directional gyroscopes, turn gyroscopes and artificial horizon. gyroscopes for providing necessary rate and atti- I 'tude indications for aircraft. In the present invention a vibrating element secured at one or both ends is employed to provide rate and attitude indications of movable craft, suitable electrical pick-off means being utilized in connection with the vibrating element to pick-of! electrical signals for operating suitable indicators giving the desired information.
One object of the present invention is to provide a novel direction indicating instrument suitable for use, among other purposes, as upon a moving craft to indicate the heading of the craft with respect to the meridian or other reference.
Another object of the invention is to provide a novel instrument adapted to serve as a rate of turn indicator for showing the rate of turn about any desired axis.
Still another object of the invention is to provide means for rigidly mounting a vibratory element at one or both ends, with means for vibrating the same, and with electrical pick-of! means therefor producing potentials adapted to control a suitable indicating means. I
A further object of the invention is to provide a direction indicator comprising an element of U-shaped or substantially tuning fork form, the
same being mounted for free movement about acentral axis extending parallel to its arms and carrying a direction indicator, together with means for vibrating the arms of said member,
whereby said arms continue to vibrate in a fixeding its deflecting plates excited by the outputs of pick-off coils associated with a horizontally vibrating rod, said cathode ray tube depicting on the face thereof an artificial horizon bar, the indications of which are similar to those of the standard artificial horizon. 1

Similar characters of reference are used in all of the'above figures to indicate corresponding parts Referring first to Figs. 1 and 2, we have shown an outer casing l, within which a round rod 2.
is rigidly secured at its lower end in the mounting support or holder 21. Rod 2 is therefore free to vibrate at its upper end. about its lower end as a center. The rate of vibration may be controlled by a mass 3 adlustably secured to the rod as by a set screw. The vibration of the rod 2 the base 21 thereof is normally maintained in an approximately horizontal plane. If the casing l tilts, the plane of vibration of the upper end of the rod 2 tilts correspondingly, the vibrating plane remaining constant with respect to the case. An evacuated glass envelope I surrounding rod 2 and sealed by a metal to glass seal to base 21 is preferably employed to lessen air resistance and to remove any spurious effects caused by air convection currents in the case I. It is to be noted that the rod 2 may be caused to vibrate at the same frequency as that of the driving voltage if the rod is not magnetically polarized, although this is not a preferred method as it is somewhat inefficient. Rod 2 which has both mass and resillence is the vibratory element of the instrument.
In order to obtain an indication or measure of the path of movement of the rod, we have shown a plurality (preferably four) of electrical pickoff coils 6, I, 8 and 9 positioned symmetrically about rod 2 on the interior wall of casing I. These coils are shown as having iron cores, II), II, III, II, respectively, that extend parallel to a narrow portion of the evacuated glass tube 4.
Assuming that the plane of vibration of the rod is in the plane of the paper, it will be evident that if the cores Ill and II. of coils 6 and I respectively, are positioned in the plane of the.
paper on each side of the rod 2, pronounced alternating voltages will be induced therein. On the other hand a substantially negligible E, M. F.
will be generated in the pick-oi! coils 8 and 9 pomtioned at right angles thereto. Should the plane of vibration of the rod be in the plane extending at right angles to the plane of the paper, considerable E. M. F. will be generated in the coils 8 and 9, and very little or no E. M. F. will appear in the coils B and 'I.- If the plane of v1- bration is at an angle between the two planes indicated, proportional E. M.'F.s will be generated in both pairs of coils dependent on the trigonometric functions of the angles the plane of vibration makes with the planes of the coils. The pair of coils 6, I are preferably connected in series opposition and coils 0, 9 similarly connected in series opposition. The resultant voltages of these pairs of coils are then connected in the manner shown in Fig. 2, through suitable amplifiers, such as l2 and i3 respectively, to operate an indicator such as the A. C. self-synchronous repeater motor 90 of the "Telegon" type having its crossed stator windings It and I connected'respectively to the outputs of amplifiers l2 and l3.
The stationary coil l8 surrounding the Z- shaped rotor or turnable magnetic core ll. of motor 90 is excited from the same A. C. source ll that excites the driving winding I through the frequency doubler 92. The output voltages of amplifiers l2 and I: may also be used to operate a cathode ray tube in the manner shown in Fig. 6, or any other type of instrument which is capable of indicating the angular orientation of the path of the free end of rod 2 or of the plane of vibration of rod 2. Thus, in employing this device as a direction indicator, as on a moving craft to take the place of a directional gyroscope, the pointer is, which may have a friction drive or other adjustable connection with the rotor ll of motor 90. is initially set so that with rod 2 vibrating this pointer will indicate a desired ref- 1 erence direction, such as magnetic north, on the degree scale l8. Then, as the craft is navigated, the reading of pointer I 8' with respect to the original scale setting of this pointer will furnish a continuous indication of the heading of the craft with respect to magnetic north.
Fig. 3 illustrates our invention adapted to serve as a rate of tumdndicator, as for moving craft. A magnetically polarized round rod 2 is symmetrically clamped in a base 26, and is excited by alternating or pulsating current supplied from leads 20 and sent through oppositely disposed coils 20 and 2| adjustably mounted on yoke 23. The natural frequency of the rod 2 may be adiusted by means of the slidably mounted weight 3 to match the frequency of the exciting current. The rod 2 then vibrates in the plane defined by the axes of the exciting coils 20 and 2|, which clearly distinguishes this form of the invention from that shown in Fig. 1, since this plane is fixed to and moves with the craft or vehicle carrying the instrument. At right angles to this plane of vibration are placed two pick-oil coils 24, one not being shown in the drawings.
When the base 26 of the instrument is turned, as when the craft turns, gyroscopie force exerted on the rod caus the end of the rod to tend to precess in a direction at right angles to the axis of the turning couple and at right angles to the axis about which the rod vibrates, causing the free end of the latter to move in an elliptically shaped path. When the rod is traveling in one direction and the base is turning, gyroscopic reaction gives the rod a component of motion up out of the plane of the paper. When the rod reaches its maximum travel and reverses its direction, these same forces operate to force it down out of the plane of the paper. Analysis and experimental evidence show that these reactions result in the rod assuming an elliptical path, the major axis of this ellipse always remaining in the plane defined by the axes of the driving coils 20 and 2|, and the length of its minor axis being functionally related to the rate of turn of the base 26, i. e., of the craft. Fig. 4 illustrates the paths which the end of the rod 2 may take under three different circumstances looking down on the instrument of Fig. 3, the pathA being that for no turn. During a clockwise turn of the base 26 at a given rate, the path rate, the path of the free end of the rod is illustrated by C, this end traveling in the opposite direction to that obtaining in B. A the rate of turn of the craft i increased or decreased, the
magnitude of the minor axis of the elliptical path increases or decreases, respectively.
These components of motion perpendicular to the plane of at-rest vibration induce alternating voltages in the pick-off coils 24. the magnitude of thes voltages depending 'on the rate of turn, and their phase-sense upon the direction of turn. 1. e., the Phase reverses with a reversal in the direction of the turn. The phase reverses because of the fact that the direction that the end of rod 2 moves past the pick-off coils 24 reverses when the craft on which the instrument is mounted changes its direction of turn. The cores 25 are rectangularly shaped and oriented as shown in the drawings to produce a mor nearly sinusoidal output. These reversing phase, variable magnitude pick-off voltages may be fed in series opposition from coils 24 into one windins of a dynamometer type meter such as shown in Fig. 13,. the other winding of this meter beinK connected to leads 20'. Alternatively these pickofl! voltages may be fed into -a thermionic phase detector to operate a direct current meter. A phase meterof the dynamometer type shown in Fig. 13 is more particularly disclosed on page 790 of the textbook published in 1940 entitled "Electrical measurements and measuring instruments" by E. W. Golding. .The device may be used to detect rate of turn about any axis when a suitable mounting is provided.
Fig. 4A shows a somewhat modified structure wherein the vibrating rod 2 is directly observed at a point in its path, preferably at an end of the minor axis of its elliptical path. This is accomplished in Fig. 4A by'use of a neon lamp 24 connected in the pulsating or alternating supply circuit leads 20. In order to adjust the point in the paths at which lamp 24 will illuminate the end of rod 2, a phase adjusting circuit such as 25' is employed. The end of the rod 2 may be colored, as by use of white pigment, so that it may be more readily seen through the slotted window'28', of the instrument 21'. In operation, when the craft makes a turn to the right the end of the rod 2 will appear to move from a. position opposite the central index 28' to the right as one looks through the window 26' as shown in Fig. 4A of the drawings. On the other hand, when the craft makes a turn to the left the end of the rod 2 will appear to mov toward the left,.i. e. will be seen at the other end of the minor axis of the path of motion of the free end of the rod, as shown in dotted lines in Fig.
3 or the sign'al from the pick-ofls may be applied to the deflecting plates 28, 31 of cathode ray tube It to giv lta visible indication of the path of vibration of the wire. The operation is essentially thesame as that of the device illustrated in Figs. 1 and 2. The wire 30 is shown as enclosed within a glass or other non-magnetic tube 22, which is preferably evacuated to reduce air resistance. Adjacent to the pick-oi! coils i, I, I and 8' the tube 32 is of reduced diameter so that the pick-off coils may b placed close to the wire. A magnetically polarized mass Il may be secured near the center of the wire 30 to decrease the period of vibration, thus decreasing the necessary length of the wire 30 and making the instrument more compact. In this instance, the wire ll which has both mass and resilience is the vibratory element of the instrument.
Our invention is adaptable for use in still another form as a directional indicator. According to this form, as shown in Fig. 7, the vibratory rod is shown as a U-shaped member 40, which is preferably magnetically polarized, and may resemble a tuning fork clamped at it bas in support 54, which, in turn, is rotatably mounted about a vertical axis in bearing members 43 and 44. The vibration of the tuning fork may be effected by circumferential three phase coil 4| excited by three phase alternating current from generator 51. To spok pieces extending from the support 54 there may be secured a compass card 45 visible through window 41 providing a reference mark cooperating with the indications of said card, and means may be provided for resetting the same by pushing in setting knob 5i carrying a bevel pinion 49 thereon adapted to engage a bevel gear on the compas card, the knob 5| being pulled outand held by detent 50 after resetting. In this typ of instrument, the tuning fork maintain its plane of oscillation by the momentum of its planar vibration. The instrument is useful in any of the three coordinates.
Another means of driving the tuning fork type of directional indicator is shown in the fragmentary view of Fig. 8. The coil 58 is rigidly at- 4A. When the vibrating rod crosses the viewing slot at its extreme left or right position of movement, viewing the instrument from the front, it is illuminated by lamp 24'. Thus, the operator is enabled by directly observing th instrument to determine whether or not the turn is to the right or to the left and the distance of the spot indicating the end of the rod from the central index 28' is a measure of the rate of turn.
Figs. 5 and 6 show another type or directional indicator employing a wire 30, which may be of magnetic material, stretched between the clamped end 35 and a drum 33 around which the free end of the wire is wound. The tension of the wire may be adjusted by a worm and worm pinion 9|] from a thumb piece 34, thereby adlusting the natural frequency of the wire to half that of the exciting current. Vibration of the wire may be produced by a three phase winding 29, excited by three phase alternating current. Pick-offs 8', I, 8', and 9' may be employed as in Fig. 2 to actuate a suitable "Telegon indicator,
tached to the base or the instrument and the coil 55 to the rotatable shaft 45. The shaft 45 being made of a magnetic material, the two coils and shaft act together as a transformer, thus avoiding the use of slip rings and supplying alternating or pulsating energy to the driving coils 52 and 53 from coil 55, coils 52 and 53 being mounted to rotate with the shaft 45.
Our invention is also adapted to use as an artificial horizon, one such form being shown in Figs. 9, 10 and 11. In this form of the invention, round magnetically polarized rod 2 is clamped at one end in the casing 58 in a horizontal position and is vibrated by an alternating or pulsating current sent through a solenoid 5. The plane of oscillation of the rod 2 .is normally maintained horizontal by electromagnets Bi secured to a bearing member 62, which is rotatably mounted on boss 9! on the interior of casing 58 in which rod 2 is secured. The axes of magnets GI are normally maintained truly horizontal by a pendulum 61 secured to the bearing member 62, so that under normal conditions the rod 2 vibrates in a, horizontal plane and therefore generates no signals in the pick-oil coils 59 and 80. If the support becomes inclined, the position of the pick-off coils will be changed with respect to the plane of vibration of the rod, which plane is by the horizontal vibrational momentum of the rod, andtherei'ore a signal will be generated in pick-off coils '59 and 80 that is. a function of ,2
' total acceleration forces on the pendulum will be slightly increased in accordance with the vector resultant of the acceleration force of gravity and the centrifugal acceleration force. As shown, the pendulum bob 6! is secured to a sleeve slidablymounted on a stem 65, the mass of the pendulum being normally just balanced by the coil spring 60. Therefore, in the presence of acceleration forces, the pendulum bob 61 will move downward slightly and thus break contacts 69,
one of which is secured to the pendulum bob 81 and the other to the fixed stem 65. These contacts 69 are normally in series with the coils ii, and when opened interrupt the restraint exerted on the vibrating rod by the coils ii. The effect of this interruption is to provide a means for averaging out normal turn errors. Two Dickofl coils 03 may be placed at right angles to the coils 59 and 60. as indicated by dotted lines in Fig. 9, for use of the instrument as part of an attitude indicator to register pitch and roll of an aircraft as shown in Fig. 9A.
' In Fig. 9A we produce on the screen of the cathode ray tube 96 a line I08 whose position in the vertical direction depends upon the angle 01' pitch of the craft and whose angle with respect to the horizontal index line II marked on the face of the tube indicates the angle of roll of the craft. This eifect is produced by the following means.
For indicating pitch we have shown schematically an instrument I06 like that of Fig. 9, with no horizontal pick-off coils 93, but with two vertically mounted pick-off coils 50" and 60", the device being mounted so that the end of the rod 2 vibrates for normal level flight in a horizontal plane parallel to the direction of flight of the aircraft, the central position of rod 2 being in the direction of flight. For indicating roll, we employ another instrument I like that of Fig. 9 which has pick-off coils mounted horizontally U3) as well as vertically (59', 60'). This instrument is mounted so that its rod 2 vibrates in a horizontal plane with the central rod position at right angles to the corresponding position of the rod 2 in instrument I06. The rods are driven by means of power supplied from generator I04 through frequency doubler 82 to exciting coils 5' and i".
From the roll axis instrument I05, alternat ng voltages'which appear in-pick-oif coils 50 and 60' are applied in series opposition to the vertical previous discussion of Flg. 9, it is evidentthat the angle this trace makes with index mark'l ll .on'the face of the screen then indicates to th pilot the anEle of roll of the craft.
As is well known in the artificial horizon art. the pitch angle is usually indicated by the distance of the center of trace I00 above or below index H4, the trace appearing above the index when the aircraft dives, and below when the craft climbs. The instrument I08 is mounted to provide this indication. The ignal from coils II" and 60" is, by means of the electronic phase detegtor I00, compared in phase with a signal from generator I04 through transformer I03, by means of diodes 01 and 00. Whenever the attitude of the craft is altered. a voltage app ars across wires I I I, II2, which is proportional to ELE: cos 0 where E1 is the voltage from transformer I00, E: is the signal voltage and 0 is the phase angle between the two voltages. This unidirectional voltage is inserted in series with the voltage derived from coils 59', and is amplified by amplifler 95, which is designed to amplify direct current as well as alternating current signals, and thence is applied to the vertical plates of cathode ray tube 06 to move the trace I00 up or down. Knobs III and H0 are provided on amplifiers 04 and 05. respectively, to furnish means for adjusting their outputs.
Another form of turn indicator type of instrument is shown in Figs. 12 and 13. In these figures the rod 2 is shown as a flat magnetically polarized rod or strip I2 clamped near one end in a bearing member I3 so that the flat surface of the rod is horizontal. Member I3 is rotatably mounted in a bracket within casing II. By fiattching the strip and by using acentralizing spring I5 extending between the short end of the strip I2 and bracket II, a vertical plane of vibration is predetermined. A-coil 80 supplied with alternating or pulsating current is shown for the purpose of vibrating the strip. Upon turn of the craft, the center of the end of the rod will depart from a vertical plane and will trace a figure 8 as shown at B in Fig. 14. The amplitude and phase of the vibration again are functionally related to the rate of turn and to the sense of turn, respectively. Due to the dissymmetry in stiffness of the fiat rod,'the clamped end of the rod will twist with the same frequency of vibration with which the other end of the rod vibrates back and forth. The behavior of the rod under these circumstances may he arrived at from obvious analysis somewhat similar to that used in discussing the rod 2 of Fig. 3.
As a pick-oil for this type of instrument, we have shown a downwardly extending permanent magnetic member I1 secured to the short end of rod 12. On each side of the lower end of the magnet are shown pick-oil coils I0 and I9. when the aircraft is at rest or moving uniformly in a straight line, the magnetic pole ll of the magnet II will remainstationary, but upon turn of the craft it will be oscillated between the pick-oi! coils at a frequency equal to the frequency of the vibration of the "rod I2 with an amplitude proportiona1 to the rate of turn and a phase depending on sense of turn. Any suitable form of indi cator may be actuated therefrom, such as a leftright turn indicator 84, which is a zero center dynamometer type meter. As is well known in the art, coil 83 of this meter is fixed and may be supplied with current of the same frequency as the driving coil 80; and coil 82, to which the 15, the rod 2 is driven by power supplied to exciter coils 20 and 2i through frequency doubler I20 from generator I2I-, The theory of operation of the rod 2 is exactly that described in discussing Fig. 3. When the craft on which the instrument is mounted is at rest or is maintaining straight line flight, the rod 2 vibrates in a straight line path in the plane defined by the axis of the rod and the coils and 2I so that the ratio of the capacity between plates I22 and I22 to that. between the plates I22 and I 24 is a constant. If the craft makes a turn, the path of the end of rod 2 opens into an ellipse, and plate I22 then has an alternating component of motion such that this capacity ratio varies with a frequency equal to that of the rod 2.
An alternating current bridge is employed and is made up of these two capacities and the condensers I21 and I28. The condenser I28 is made variable so that the ratio of the capacities of condensers I28 to I21 may be made the same at the ratio of the capacities between plates I22 and I23 to that between plates I22and I24 for straight line vibration of the rod 2 corresponding to straight flight. To one diagonal of this bridge is applied an alternating current of frequency f (on the order of 10,000 cycles) generated by oscillator I25 and fed through transformer I26. As long as the rod vibrates in a straight line parallel to the plates, the bridge remains balanced; but
when the pick-off capacity ratio varies due to a turn of the craft, a voltage of the frequency 1 modulated by the frequency of the rod 2 appears at the other diagonal of the bridge and is impressed across series resistors l29 and I30. -By means of triodes I32 and I33, this signal is amplitied and fed to the detector circuit I35, which removes the frequency 1 signal, leaving a low frequency voltage. The magnitude of this low frequency voltage depends upon the rate of turn of the craft, and its phase-sense upon the direction of the turn.
The phase detector I38 operates in a similar manner to that shown as circuit I09 in Fig. 9A.
In phase detector I38, the reversing phase low frequency signal voltage is compared to, the phase of the standard signal provided by generator I2I. The indicator I21 may be any of the devices suggested for operation with the instrument shown in Fig. 3. The device is useful in any of the three coordinates, if suitable mounting is provided.
Also, while we have not heretofore referred, to .our invention as a gyroscope, since the motion ings shall be interpreted as illustrative and not in a limiting sense.

A Taupo man still hopes to solve a decades-old mystery of a World War I era trophy.
So far owner Garry Carlyle has been unable to find anyone with knowledge of the competition it marked.
He stumbled across the 75 yards Taupo Dash trophy, won by World War I veteran W Martin on Easter Monday in 1920, while cleaning out his mother's house in Taupo recently.
Carlyle said the story behind the Walker and Hall hallmark 1916 silver vase and what event it was made for has been a mystery for 40 years.
"My granddad was living in an old folks' village in Hamilton and the trophy belonged to his neighbour who was dying. Granddad said his daughter was coming back to Taupo and she would return it here," he said.
"My mother brought it back just before my grandfather died, but the Taupo Museum didn't want it, nobody wanted it."
Carlyle believes it could be from Taupo's first major sporting event.
"I asked mum what should happen with it [when sorting her place out] and she said to give it to the Salvation Army because nobody wanted it, then I read it and said 'no it's important' and I started to make inquiries," he said.
The closest he's come to a possible clue was when contacting the National Army Museum in Waiouru.
"They helped the best they could and found out about a soldier called Walter George Martin from Rotorua," he said.
"A lot of returned servicemen at the time were working on the rail link to Taupo because there was very little work after the war and he seems to be the closest fit.
"I also phoned Walker and Hall in Auckland to see if I could trace it back to the original purchaser in England.
He was yet to hear back.
Carlyle said a friend told him it was common to have races after the war where soldiers were carried by other soldiers over a certain distance and he would like to see some sort of event resurrected.
Taupo Mayor David Trewavas said he too would like to see an event involving the trophy.
"It is quite neat because although we have a lot of history with bits and pieces there is nothing sporty.
"It sounds like it was an annual race between services and it would be great to get an event running again as part of our World War I centenary celebrations next year," he said.
Trewavas suggested something may be held around the same time as the original event and involving the fire brigade and police.
"I think as far as sporting events in Taupo go, this trophy has probably unearthed the oldest and that is exciting," he said.

NYC the weekend after Thanksgiving?
Report Abuse
No, not too early. The Rock Center tree lighting is usually the Monday after Thanksgiving, and the stores' Xmas windows are up the week BEFORE Thanksgiving.

Thnak you! That's very helpful.

Correction on the date of the Rockefeller Center Christmas tree lighting ceremony. It will take place Wednesday, December 1, not on the preceding Monday.

Great tiem to be in the city - BUT
Day after Thanksgiving is Black Friday , many stores open at 6 or 7 an to start holiday shopping, everything is mobbed, hotels are at max price and and I believe the Friday or Sat is the first gridlock alert day (when traffic is so bad it actually comes to a standstill - and everyone is instructed to use public transit only).
So be ready to love it - but be prepared.

The OP is talking about the weekend AFTER Thanksgiving weekend, so Black Friday wouldn't apply here.

I guess I phrased my post strangely. We'll be there for one night, the Saturday night directly after Thanksgiving. We're not planning to shop though, just look, but we'll be ready for massive crowds! Thankfully, we're taking the train from CT to NYC.
As always, your replies were much appreciated!

Well, then, you'll miss the tree, but still be able to see the windows.

So, I guess you were right after all, nytraveler!
