This application is a divisional application of U.S. patent application Ser. No. 10/773,102, now U.S. Pat. No. 7,402,276, filed on Feb. 4, 2004, which is a continuation-in-part of U.S. patent application Ser. No. 10/619,405, now U.S. Pat. No. 7,507,367, filed on Jul. 14, 2003 and a continuation of U.S. patent application Ser. No. 10/620,318, now U.S. Pat. No. 7,731,891, filed on Jul. 14, 2003.
The invention relates to a device used in a pump, particularly a pump for pumping molten metal, wherein the pump operates in an environment containing solid pieces of material that could jam the pump by lodging between a rotating rotor and a stationary inlet.
As used herein, the term "molten metal" means any metal or combination of metals in liquid form, such as aluminum, copper, iron, zinc and alloys thereof. The term "gas"means any gas or combination of gases, including argon, nitrogen, chlorine, fluorine, freon, and helium, that are released into molten metal.
Known pumps for pumping molten metal (also called "molten-metal pumps") include a pump base (also called a housing or casing), one or more inlets, an inlet being an opening to allow molten metal to enter a pump chamber (and is usually an opening in the pump base that communicates with the pump chamber), a pump chamber, which is an open area formed within the pump base, and a discharge, which is a channel or conduit communicating with the pump chamber (in an axial pump the pump chamber and discharge may be the same structure or different areas of the same structure) leading from the pump chamber to the molten metal bath in which the pump base is submerged. A rotor, also called an impeller, is mounted in the pump chamber and is connected to a drive shaft. The drive shaft is typically a motor shaft coupled to a rotor shaft, wherein the motor shaft has two ends, one end being connected to a motor and the other end being coupled to the rotor shaft. The rotor shaft also has two ends, wherein one end is coupled to the motor shaft and the other end is connected to the rotor. Often, the rotor shaft is comprised of graphite, the motor shaft is comprised of steel, and the two are coupled by a coupling, which is usually comprised of steel.
As the motor turns the drive shaft, the drive shaft turns the rotor and the rotor pushes molten metal out of the pump chamber, through the discharge, which may be an axial or tangential discharge, and into the molten metal bath. Most molten metal pumps are gravity fed, wherein gravity forces molten metal through the inlet and into the pump chamber as the rotor pushes molten metal out of the pump chamber.
Molten metal pump casings and rotors usually employ a bearing system comprising ceramic rings wherein there are one or more rings on the rotor that align with rings in the pump chamber (such as rings at the inlet (which is usually the top of the pump chamber and bottom of the pump chamber) when the rotor is placed in the pump chamber. The purpose of the bearing system is to reduce damage to the soft, graphite components, particularly the rotor and pump chamber wall, during pump operation. A known bearing system is described in U.S. Pat. No. 5,203,681 to Cooper, the disclosure of which is incorporated herein by reference. As discussed in U.S. Pat. Nos. 5,591,243 and 6,093,000, each to Cooper, the disclosures of which are incorporated herein by reference, bearing rings can cause various operational and shipping problems and U.S. Pat. No. 6,093,000 discloses rigid coupling designs and a monolithic rotor to help alleviate this problem. Further, U.S. Pat. No. 2,948,524 to Sweeney et al., U.S. Pat. No. 4,169,584 to Mangalick, U.S. Pat. No. 5,203,681 to Cooper and U.S. Pat. No. 6,123,523 to Cooper (the disclosures of the afore-mentioned patents to Cooper are incorporated herein by reference) all disclose molten metal pumps.
The materials forming the components that contact the molten metal bath should remain relatively stable in the bath. Structural refractory materials, such as graphite or ceramics, that are resistant to disintegration by corrosive attack from the molten metal may be used. As used herein "ceramics" or "ceramic" refers to any oxidized metal (including silicon) or carbon-based material, excluding graphite, capable of being used in the environment of a molten metal bath. "Graphite" means any type of graphite, whether or not chemically treated. Graphite is particularly suitable for being formed into pump components because it is (a) soft and relatively easy to machine, (b) not as brittle as ceramics and less prone to breakage, and (c) less expensive than ceramics.
Three basic types of pumps for pumping molten metal, such as molten aluminum, are utilized: circulation pumps, transfer pumps and gas-release pumps. Circulation pumps are used to circulate the molten metal within a bath, thereby generally equalizing the temperature of the molten metal. Most often, circulation pumps are used in a reverbatory furnace having an external well. The well is usually an extension of a charging well where scrap metal is charged (i.e., added).
Transfer pumps are generally used to transfer molten metal from the external well of a reverbatory furnace to a different location such as a ladle or another furnace. Examples of transfer pumps are disclosed in U.S. Pat. No. 6,345,964 B1 to Cooper, the disclosure of which is incorporated herein by reference, and U.S. Pat. No. 5,203,681.
Gas-release pumps, such as gas-injection pumps, circulate molten metal while releasing a gas into the molten metal. In the purification of molten metals, particularly aluminum, it is frequently desired to remove dissolved gases such as hydrogen, or dissolved metals, such as magnesium, from the molten metal. As is known by those skilled in the art, the removing of dissolved gas is known as "degassing" while the removal of magnesium is known as "demagging." Gas-release pumps may be used for either of these purposes or for any other application for which it is desirable to introduce gas into molten metal. Gas-release pumps generally include a gas-transfer conduit having a first end that is connected to a gas source and a second submerged in the molten metal bath. Gas is introduced into the first end and is released from the second end into the molten metal. The gas may be released downstream of the pump chamber into either the pump discharge or a metal-transfer conduit extending from the discharge, or into a stream of molten metal exiting either the discharge or the metal-transfer conduit. Alternatively, gas may be released into the pump chamber or upstream of the pump chamber at a position where it enters the pump chamber. A system for releasing gas into a pump chamber is disclosed in U.S. Pat. No. 6,123,523 to Cooper. Furthermore, gas may be released into a stream of molten metal passing through a discharge or metal-transfer conduit wherein the position of a gas-release opening in the metal-transfer conduit enables pressure from the molten metal stream to assist in drawing gas into the molten metal stream. Such a structure and method is disclosed in a copending application entitled "System for Releasing Gas Into Molten Metal," invented by Paul V. Cooper, and filed on Feb. 4, 2004, the disclosure of which is incorporated herein by reference.
When a conventional molten metal pump is operated, the rotor rotates within the pump housing and the pump housing, inlet and pump chamber remain stationary relative to the rotor, i.e., they do not rotate. A problem with such molten metal pumps is that the molten metal in which it operates includes solid particles, such as dross and brick. As the rotor rotates molten metal including the solid particles enters the pump chamber through the inlet. A solid particle may lodge between the moving rotor and the stationary inlet, potentially jamming the rotor and potentially damaging one or more of the pump components, such as the rotor or rotor shaft of the pump.
Many attempts have been made to solve this problem, including the use of filters or disks to prevent solid particles from entering the inlet and the use of a non-volute pump chamber to increase the space between the inlet and rotor to allow solid pieces to pass into the pump chamber without jamming, where they can be pushed through the discharge by the action of the rotor.
The present invention alleviates these problems by providing a device that essentially combines the inlet and rotor into a single component that rotates in the pump base. Consequently, solid particles cannot jam between a moving rotor and a stationary inlet since the inlet rotates with the rotor blades. The device includes a displacement structure, such as rotor blades, for displacing (i.e., moving) molten metal, and an inlet structure that defines one or more inlets (i.e., openings) through which molten metal can pass.
The displacement structure is preferably a plurality of imperforate rotor blades. The rotor blades may be of any size or configuration suitable to move molten metal in a pump chamber, and are preferably configured to move molten metal both downward towards the bottom of the pump chamber and outward through the pump discharge. However, any structure suitable for displacing molten metal in a pump camber may be used.
The inlet structure can be of any size or configuration suitable for defining one or more openings through which molten metal may pass. Molten metal can pass through the openings where it ultimately enters the pump chamber and is displaced by the displacement structure.
The device also may include a flow-blocking plate to block an opening in the bottom or top of the pump base and a bearing surface for aligning with a corresponding bearing surface on a pump base, but the flow-blocking plate and bearing surface are each optional.
Preferably, the device is positioned in the pump chamber of a molten metal pump. The device is attached to a drive shaft and is rotated as the drive shaft rotates. In operation, as the device rotates within the pump chamber molten metal enters the opening(s) of the inlet structure and is displaced from the pump chamber into the discharge by the displacement structure.
If a device according to the invention includes one or more bearing surfaces, the bearing surfaces may have one or more grooves formed therein. The groove(s) may be of any shape or size sufficient to help alleviate a build up of molten metal between the device's bearing surface(s) and the corresponding bearing surface(s) on a pump base. Alternatively, the grooves may be formed on the bearing surface of the pump base or on both the bearing surface(s) of the pump base and the bearing surface(s) of the device. Moreover, not just a device as described herein, but any impeller for use in molten metal, wherein the impeller includes a bearing surface, could utilize grooves in the bearing surface according to the invention.
Referring now to the drawing where the purpose is to illustrate and describe different embodiments of the invention, and not to limit same,
The components of pump 20, including device 100, that are exposed to the molten metal are preferably formed of structural refractory materials, which are resistant to degradation in the molten metal. Carbonaceous refractory materials, such as carbon of a dense or structural type, including graphite, graphitized carbon, clay-bonded graphite, carbon-bonded graphite, or the like have all been found to be most suitable because of cost and ease of machining. Such components may be made by mixing ground graphite with a fine clay binder, forming the non-coated component and baking, and may be glazed or unglazed. In addition, components made of carbonaceous refractory materials may be treated with one or more chemicals to make the components more resistant to oxidation. Oxidation and erosion treatments for graphite parts are practiced commercially, and graphite so treated can be obtained from sources known to those skilled in the art.
Pump 20 can be any structure or device for pumping or otherwise conveying molten metal, such as the pump disclosed in U.S. Pat. No. 5,203,681 to Cooper, or an axial pump having an axial, rather than tangential, discharge. Preferred pump 20 has a pump base 24 for being submersed in a molten metal bath. Pump base 24 preferably includes a generally nonvolute pump chamber 26, such as a cylindrical pump chamber or what has been called a "cut" volute, although pump base 24 may have any shape pump chamber suitable of being used, including a volute-shaped chamber. Chamber 26 may be constructed to have only one opening, either in its top or bottom, if a tangential discharge is used, since only one opening is required to introduce molten metal into pump chamber 26. Generally, pump chamber 24 has two coaxial openings of the same diameter and usually one is blocked by a flow blocking plate mounted on the bottom of, or formed as part of, device 100. As shown, chamber 26 includes a top opening 28, bottom opening 29, and wall 31. Base 24 further includes a tangential discharge 30 (although another type of discharge, such as an axial discharge may be used) in fluid communication with chamber 26. Base 24 has sides 112, 114, 116, 118 and 120 and a top surface 110. The top portion of wall 31 is machined to receive a bearing surface, which is not yet mounted to wall 31. The bearing surface is typically comprised of ceramic and cemented to wall 31.
One or more support post receiving bores 126 are formed in base 24 and are for receiving support posts 34. In this embodiment, pump base 24 receives a gas-transfer conduit in stepped opening 128, which includes first opening 128A and second opening 128B defined by a bore 112. The invention is not limited to any particular type or configuration of base, however. A pump base used with the invention could be of any size, design or configuration suitable for utilizing a device or impeller according to the invention.
Pump base 24 is also described in copending application entitled "System for Releasing Gas Into Molten Metal" to Paul V. Cooper and filed on Feb. 4, 2004.
As shown in
One or more support posts 34 connect base 24 to a superstructure 36 of pump 20 thus supporting superstructure 36, although any structure or structures capable of supporting superstructure 36 may be used. Additionally, pump 20 could be constructed so there is no physical connection between the base and the superstructure, wherein the superstructure is independently supported. The motor, drive shaft and rotor could be suspended without a superstructure, wherein they are supported, directly or indirectly, to a structure independent of the pump base.
In the preferred embodiment, post clamps 35 secure posts 34 to superstructure 36. A preferred post clamp and preferred support posts are disclosed in a copending application entitled "Support Post System for Molten Metal Pump," invented by Paul V. Cooper, and filed on Feb. 4, 2004, the disclosure of which is incorporated herein by reference.
A motor 40, which can be any structure, system or device suitable for driving pump 20, but is preferably an electric or pneumatic motor, is positioned on superstructure 36 and is connected to an end of a drive shaft 42. A drive shaft 42 can be any structure suitable for rotating an impeller, and preferably comprises a motor shaft (not shown) coupled to a rotor shaft. The motor shaft has a first end and a second end, wherein the first end of the motor shaft connects to motor 40 and the second end of the motor shaft connects to the coupling. Rotor shaft 44 has a first end and a second end, wherein the first end is connected to the coupling and the second end is connected to device 100 or to an impeller according to the invention. A preferred coupling, rotor shaft and connection between the rotor shaft and device 100 are disclosed in a copending application entitled "Molten Metal Pump Components," invented by Paul V. Cooper and filed on Feb. 4, 2004, the disclosure of which is incorporated herein by reference.
The preferred device 100, seen best in
Device 100 is preferably circular in plan view (although device 100 can be of any shape suitable for use in a molten metal pump) and includes a displacement structure 102, an inlet structure 104, a top surface 106, a bottom surface 108, and a connective portion 110.
Displacement structure 102 is any structure(s) or device(s) suitable for displacing molten metal in a pump casing and through the discharge. Structure 102 preferably comprises one or more imperforate rotor blades (as best seen in
Displacement structure 102 as shown has three rotor blades, or vanes, 102A, 102B and 102C, for displacing molten metal, although any number of vanes could be used. Displacement structure 102 preferably has a structure that directs flow into pump chamber 26 and a structure that directs flow towards pump chamber wall 31. Preferably this structure is either (1) one or more rotor blades with a portion that directs molten metal into chamber 26 and a portion that directs molten metal outward towards chamber wall 31, or (2) at least one vane that directs molten metal into pump chamber 26, and at least one vane that directs molten metal towards chamber wall 31. In the preferred embodiment each vane 102A, 102B and 102C has the same configuration (although the respective vanes could have different configurations) so only one vane will be described in detail.
Vane 102A preferably includes a vertically-oriented portion 130 and a horizontally-extending portion 132. The respective vertical and horizontal orientation of the portions described herein is in reference to device 100 positioned in a standard pump having an opening in the top surface of the pump housing through which molten metal can enter the pump chamber, and wherein device 100 is oriented around a vertical axis Y as shown in
In the preferred embodiment, when device 100 is mounted in pump chamber 26, portion 132 (also called a projection or horizontally-extending projection) is positioned closer to opening 28 than portion 130. This is because the molten metal in bath B outside of chamber 26 should first be directed into chamber 26 before being directed outward towards chamber wall 31 and ultimately through discharge 30. Projection 132 has a top surface 134 preferably flush with top surface 106 and opening 28, and a bottom surface 136. However, top surface 134 and projection 132 may be positioned partially or entirely outside or inside of chamber 26.
Projection 132 further includes a leading edge 138 and an angled surface (or first surface) 140, which is preferably formed in surface 134 adjacent leading edge 138. As will be understood, surface 140 is angled (as used herein the term angled refers to both a substantially planar surface, or a curved surface, or a multi-faceted surface) such that, as device 100 turns (as shown in
Leading edge 138 has a thickness T. Thickness T is preferably about �″ and prevents too thin an edge from being formed when surface 140 is machined into projection 132. This reduces the likelihood of breakage during shipping or handling of device 100, but is not related to the overall function of device 100 during operation of pump 20.
Portion 130, which is preferably vertical (but can be angled or curved), extends from the back (or trailing portion) of projection 132 to surface 108. Portion 130 has a leading face (or second surface) 144 and a trailing face 146. Leading face 144 is preferably planar and vertical, although it can be of any configuration that directs molten metal outward against wall 31 of chamber 26.
A recess 150 is formed in top surface 106 and preferably extends from top surface 106 to trailing face 146. As shown, recess 150 begins at a position on surface 106 slightly forward of face 146 and terminates at a position on face 146. The purpose of recess 150 is to reduce the area of top surface 106, thereby creating a larger opening for molten metal to enter chamber 26, which increases the output of pump 20 and can lead to lower operating speeds, less pump vibration and longer component life.
Inlet structure 104 preferably has three inlet perimeters 104A, 104B and 104C that help to define inlets (or openings) 106A, 106B and 106C, as best seen in
Inlets 106A, 106B and 106C can be any size or shape suitable for allowing molten metal to pass into pump chamber 26 so the molten metal can be displaced by displacement structure 102. Additionally, any number of inlets suitable for a given displacement structure configuration may be used. Preferably, the inlet(s) are as large as possible to allow for the maximum flow of molten metal into chamber 26.
Device 100 also has a connective portion 110 to connect to end 38B of rotor shaft 38. Connective portion 110 preferably has includes a threaded bore 110A that threadingly receives second end 38B of rotor shaft 38, although any connection capable of attaching shaft 38 to device 100 and that enables shaft 38 to rotate device 100 may be used. A preferred flat-thread configuration is best seen in
An optional flow-blocking and bearing plate, 112 is mounted on either the top 106 or bottom 108 of device 100, depending upon the location of the pump inlet. Plate 112 is preferably comprised of ceramic, is cemented to top 106 or bottom 108, and is sized to rotatably fit and be guided by the appropriate one of bearing ring members 60 or 60A mounted in pump casing 24, shown in
Further, if pump 20 was a dual inlet pump, having inlets at the top and bottom of pump chamber 24 and device 100 had no flow blocking plate, the device according to the invention would preferably have one or more inlets formed adjacent top surface 106, as shown, and one or more inlets formed in bottom surface 108, wherein the top and bottom inlets would preferably rotate as the device rotated. However, the invention covers a device wherein the inlet(s) are at either the top or bottom of the device or both, when used in a dual-flow pump, and the inlets rotate as the device rotates.
As device 100 is rotated by drive shaft 12, displacement structure 102 and inlet structure 104 rotate. Thus, in the preferred embodiment, rotor blades 102A, 102B and 102C and inlets 106A, 106B and 106C rotate as a unit. Therefore, solid particles in the molten metal cannot lodge between a rotating rotor and a stationary inlet. This reduces the likelihood of a solid particle jamming between the inlet and the rotor and causing damage to any of the pump components.
In the embodiment shown, top surface 108 of device 100 is substantially flush with the top surface of pump base 26. However, device 100 may be sized or positioned so it extends beyond the top surface of pump base 26, or device 100 may include projections that extend beyond the top surface of base 26 to deflect solid particles.
Having thus described different embodiments of the invention, other variations and embodiments that do not depart from the spirit of the invention will become apparent to those skilled in the art. The scope of the present invention is thus not limited to any particular embodiment, but is instead set forth in the appended claims and the legal equivalents thereof. Unless expressly stated in the written description or claims, the steps of any method recited in the claims may be performed in any order capable of yielding the desired product.

Between the hours of 8 and 10 p.m Saturday night 1.5 million fans tuned in to watch UFC 198 prelims (786,000 viewers) and Bellator (709,000 viewers).
UFC 198 prelims were headlined by Demian Maia and Matt Brown. The main event saw Maia defeat Brown via rear-naked choke, much to the pleasure of the Brazilian crowd. In fact, had you tuned in you might have seen a tussle between Brown and multiple fans during his walkout.
Bellator's card was headlined by Phil Davis and King Mo Lawal in San Jose, California. Davis ended up de-crowning Mo via decision. This card was also particularly important as it was first show since Bellator fighter Jordan Parson's passing.
Both cards were the top watched live sports events on television that night.
I'm curious which of the big shows you tuned in to watch?
Which card did you watch on Saturday night?

Get email delivery of the Cadence blog featured here
I always thought that IT departments worked in the background and had no visibility outside the corporate walls. This is not true at Cadence, where IT experts work with the services group to help customers develop and improve their CAD infrastructures - as well as maintain internal "chambers" that provide various levels of compute capability.
As a result, Cadence has resident experts in topics such as cloud computing, geographically-dispersed multi-team collaboration, data security, and "best practices" for improving performance and stability. I plan to tap some of that expertise for future blog posts. But first, I'll provide a brief introduction to the EDA Infrastructure Acceleration Services and hosted chambers offered by Cadence.
Why provide such services? Because building and maintaining a CAD infrastructure is a huge effort and expense, especially for small companies and startups. Even large "power users" frequently run into bottlenecks and need some outside help. Yet most EDA vendors focus only on tools, ignoring the environment in which the tools must run. The EDA360 vision paper notes that the EDA industry must begin to serve project-level and corporate-level needs. The EDA Infrastructure Acceleration Services represents a step in that direction.
"A few years ago, Cadence IT management launched a strategy to redirect the technical expertise and experience of our internal IT professionals towards helping our EDA customers more rapidly achieve their objectives," said Dan Salisbury, corporate vice president for Global IT. "The result has been very uplifting. Our EDA customers value the technical support, our IT professionals have gained expertise, and a larger percentage of our traditional internal IT investment is now spent helping our EDA clients."
Improving the Infrastructure
EDA Infrastructure Acceleration Services is an umbrella term that includes these capabilities:
Peter Vincent, senior IT architect for customer enablement at Cadence, noted that IT experts work closely with AEs to provide these services. The top three customer problems, he said, involve Linux, storage, and networking. To solve customer problems, the Cadence consultants will look at the components of the compute farm, the distributed resource manager, the network configuration, the OS, the desktop system, and any tool or methodology issues that may be getting in the way. One deliverable is a "gap analysis report" with recommendations for solving the problem.
But, don't most large customers buy tools from multiple EDA vendors? Not a problem, Peter said. "We maximize the performance of the infrastructure layer. We don't touch your [non-Cadence] tools, IP, or data. We handle the foundations of the house. The home you build on top of it is your choice."
In-House Options
For many years Cadence has offered secure VCAD (Virtual Integrated CAD) "chambers" located at Cadence. Customers can use VCAD chambers to facilitate Cadence support, to store test cases, or to collaborate on design data. More recently, Cadence has offered "hosted chambers" that include servers, storage, and tool licenses, providing a complete CAD infrastructure environment for many small companies and startups. The latest incarnation of this concept is Hosted Design Services, Cadence's software as a service (SaaS) offering.
All of the offerings described in this post - including the EDA Infrastructure Acceleration Services, VCAD chambers, and Hosted Design Services - are sold through the Cadence services organization. However, all leverage expertise and personnel from the Cadence IT department.
"We're promoting what Cadence IT can do for customers rather than just being an internally-facing organization," Peter said. "There's no rocket science here. We're just taking guys who know an awful lot and helping our customers solve some common problems."

Brothers from the Bottom will commemorate the 10th anniversary of Hurricane Katrina and star Tony Award winner Wendell Pierce in a limited engagement. Here's the press release:
Following their acclaimed Brooklyn run, the award-winning Billie Holiday Theater (BHT) at Bedford Stuyvesant Restoration Corporation and the New Orleans Center for Creative Arts (NOCCA) Stage Company join forces to present the Post-Katrina play set in New Orleans, Brothers from the Bottom, starring Wendell Pierce who also joins this team, as a producer. The limited engagement, in commemoration of the 10th year anniversary of Hurricane Katrina, will run from June 5 – 28, 2015 at the Lupin Hall at NOCCA.
Brothers from the Bottom, written and directed by BHT Artistic Director, Jackie Alexander, deals with the hot button topic of gentrification. In the play, a real estate project threatens the fabric of a New Orleans neighborhood, and unravels the bond between brothers. In this "naturalistic play," "the acting stands way above the flood line." With a "terrific" performance by Mr. Pierce and a "particularly exuberant" performance by Kevin Mambo, the play is "ground[ed] by the actor's sensitivity and verve. The neighborhood may need renewal and repair. These performances don't." – New York Times
Wendell Pierce, an accomplished Julliard trained actor, has conquered all realms of media with critically praised performances in theater, film, television and broadcast radio. The TONY, Emmy, Obie and Peabody winning actor and producer is best known for his portrayals on HBO's ground breaking television series' The Wire and Treme. Pierce was also in this year's Oscar nominee for Best Picture, SELMA. Pierce will also soon be releasing a personal memoir, THE WIND IN THE REEDS, an insightful and poignant portrait of family, New Orleans and the transforming power of art (RIVERHEAD BOOKS / Sept. 8th, 2015). Pierce states, "The 10th Anniversary of Hurricane Katrina is a significant moment in the recent history of our country. Brothers from the Bottom does what art does best: challenge, elevate and illuminate the conversation."
The cast includes two-time Emmy Award winner Kevin Mambo, who played the title role in Fela! on Broadway, as well as Toccarra Cash, Thaddeus Daniels, Wendell Franklin andMegan Robinson.
Brothers from the Bottom, writer and director, Alexander, is a prolific award winning actor, writer, producer and director for theater and film.
With: Original Music: Edward Anderson and Darrell Lavigne (Bleu Orleans); Set Design: Felix Cochren (Broadway credits: Amen Corner, Inacent Black, Home); Assistant Set Designer: Patrice Davidson; Costume Design: Helen Simmons-Collen; Lighting Design: Joyce Liao; Sound Design: Douglas Forbes; Stage Manager: Norman Smalls
NOCCA Stage Company is excited to provide this once in a lifetime chance for NOCCA students to work directly with these incredible artists that are part of Brothers from the Bottom. Work on set building and staging, masterclass rehearsals begins in mid-May which provides the perfect big picture insight to the students in the Theatre Arts Department at NOCCA. NOCCA is proud to be part of this incredible moment that will shape the local theatre scene for many years to come.

Motorists need to be aware that Moose are on the move in late May and June, and statistics show that there are more moose vehicle crashes June than any other month of the year.
"Moose frequent roadways during the late spring and early summer," said Roland D. Martin, Commissioner, Department of Inland Fisheries and Wildlife. "Drivers need to be alert when driving in areas populated by moose, and be certain to use their seatbelts."
Moose travel to roadways for several reasons. After a long winter of eating poor-quality food, their bodies crave the salt that is found along roadsides. The sides of roads are also the first areas to green up in the spring, offering tender plant shoots as another source of food for moose. And yearling moose, recently forced away by their mothers as the
mothers prepare to give birth to this year's calves, often travel and find themselves around roads.
Nighttime is also peak time for moose-vehicle collisions. The number of moose crashes peaks between 7:00 p.m. and midnight. Moose move more during the evening after it cools from the daytime high temperatures.
Moose collisions can happen anywhere in the state, and the state averages roughly 3 fatalities a year. As a driver, there are several steps you can take to minimize the chance of being involved in a moose-vehicle collision.
"A moose vehicle accident can cause serious injury, or even death." Said Colonel Thomas Santaguida of the Maine Warden Service. "Statistics show that one of every four moose-vehicle crashes causes significant injury."
With their dark brown color, moose are difficult to see at night, and because of their height, their eyes do not readily reflect oncoming headlights. They also tend to move in groups. If you see one, slow down, because there may be another, and be on the lookout for tall silhouettes along roadsides.
