Title: Apparatus and method for cooling high-temperature fuel cell stacks
Inventor: PETRIK MICHAEL A
IPC: H01M8/12
Filed: 2000-10-30
Abstract: An electrochemical apparatus and method for cooling the same. The apparatus comprises a stack of at least two compact cells. The cells have a maximum thermal pathway of about 4 centimeters. The cell includes a solid electrode layer disposed between an oxygen electrode layer and a fuel electrode layer. A separator layer contacts the surface of opposing electrodes of adjacent cells. The cell defines internal passages, for providing reactant gases to the electrodes, and a rim portion of the cell is adapted to radiate heat generated within the cell to outside the cell. At least one layer of the cell is adapted to conduct the cell heat to the rim for transfer by radiative cooling. The method of cooling the above apparatus includes feeding oxygen-bearing gas to the oxygen electrode at a low flow rate, conducting the heat produced within the cell to the cell rim, and radiating the heat from the cell rim.

Title: Refining of metallurgical grade silicon
Inventor: CECCAROLI BRUNO
IPC: C01B33/037
Filed: 2000-11-08
Abstract: The invention relates to a method for purification of metallurgical grade silicon where a calcium containing compound is added to molten silicon prior to or after the silicon is tapped from the furnace. The silicon is cast and solidified at a relatively high cooling rate and the solidified silicon is crushed and subjected to a purification process consisting of two leaching steps. In the first leaching step the silicon is treated with an aqueous solution of FeCl3 or FeCl3 and HCl which causes disintegration of the silicon, and in the second leaching step the silicon is treated with an aqueous solution of HF or HF/HNO3. Calcium-containing compound is added to the molten silicon in an amount necessary to provide between 0.3 and 0.95 % by weight of calcium in the molten silicon and the weight ratio between Al and Fe in the molten silicon is regulated to between 0.5 and 2.0 by addition of aluminum to the molten silicon.
Patent CA-2394485-A1 (CA)
Inventor: HOTZ WALTER
IPC: C22C21/00
Filed: 2000-11-30
Abstract: The invention relates to a method for producing a grain refiner on the basis  of an aluminum-titanium-boron prealloy. According to the inventive method, starting materials that contain Ti and B are introduced into an aluminum mel t while TiB2 particles are formed, and the prealloy melt produced is allowed t o solidify. The prealloy is set in motion at a temperature between the liquidu s temperature (TLAl3Ti) of the Al3Ti phase and the solidus temperature (TSV) o f the prealloy for a period (.DELTA.td) sufficient to disperse the TiB2 particles in the melt. The melt is simultaneously cooled off at a first rate  of cooling (v1) so that the TiB2 particles function as the nuclei for the Al3Ti phase that is formed below the liquidus temperature (TLAl3Ti) and the surface of the TiB2 particles is at least partially covered by an Al3Ti coating. The prealloy is then cooled off to a temperature below the solidus temperature (TSV) of the prealloy at a second rate of cooling (v2) that is higher than the first rate of cooling (v1). The inventive method is especial ly useful in the production of grain refiners for the grain refinement of aluminum and aluminum alloys.

Patent CA-2402289-A1 (CA)
Title: Fluid treatment system and method of treating fluid
Inventor: MAO TED
IPC: A61L2/10
Filed: 2001-03-12
Abstract: It is often desirable to operate ultraviolet (UV) water treatment systems at high fluid velocities; such as, when low UV doses are required, the UV  transmittance of the water being treated is high, or when a high intensity radiation source is used. The operation of an open channel UV fluid treatment system at high fluid velocity causes a disproportionate amount of water to pass through the relatively low intensity region above the top lamp. This results in non-uniform UV dose delivery and poor reactor performance. In one embodiment of the invention, by elevating the inlet to the irradiation zone of the fluid treatment system with respect to the outlet, the amount of water that passes above the top lamp can be minimized, improving overall system performance. The means of elevation can consist of a step or slope in the channel, or a combination of both. Depending on the magnitude of elevation, an increase in maximum velocity of approximately two times can be obtained. In practice, a means must be provided to prevent damage to the radiation sources of the elevated banks that become exposed during periods of low flow. This can consist of either a mechanism for switching off the affected lamp when low water level or high temperature is detected, or a means of lamp cooling.

Title: Optical signalling system
Inventor: HILL ALAN MICHAEL
IPC: H04Q11/00
Filed: 2001-02-16
Abstract: In an optical signalling system, simultaneous signals are circulated on a looped path and fed out sequentially to a tuneable receiver. Conversely, sequential signals may be buffered in the loop and fed out simultaneously to a number of receivers. The system is suitable for use in a passive optical network employing wavelength-dependent routing, terminals transmit request packets (requesting a data transmission slot) in a common signalling time slot. Different delays are then applied to packets on different wavelength channels, allowing a number of request packets to be processed in sequence by a single optical receiver at the network controller.

Title: Method for making dutched cocoa
Inventor: TROUT RICHARD B
IPC: A23G1/04
Filed: 2001-05-01
Abstract: A method for making dutched cocoa involves first removing a considerable portion of the fat from a cocoa mass to form a reduced fat cocoa mass with less than 8 % fat by weight, then alkalizing the reduced fat cocoa to form dutched cocoa. With this sequence of steps, the formation of soaps is minimized because the soaps are formed by a reaction between the alkalizing agents and cocoa fat. Thus, the taste of the cocoa powder is improved, as we ll as its flowability, especially when the cocoa undergoes harsh alkalizing conditions, as is required for applications requiring very dark cocoa.</SDOA B>

Abstract: A vapor collection method and apparatus capable of capturing vapor compositions without substantial dilution. The method and apparatus utilize a material (12) that has a surface (14) with an adjacent gas phase. A chamber (16) is positioned in close proximity to a surface (14) of the material (12) .
