Granted: 2003-10-07
Abstract: The molten carbonate fuel cell includes (a) an anode current collector formed to be flat rectangular tubular and having a pair of outer surfaces each formed at the center thereof with a recessed portion for receiving an anode therein, the recessed portion being formed with a plurality of holes through which anode gas is supplied to anode from inside of the anode current collector,(b) a pair of cells each disposed on each of the outer surfaces of the anode current collector, and (c) a pair of cathode current collectors each cooperating with the anode current collector to sandwich each of the cells therebetween, the cathode current collectors being formed with a plurality of holes through which cathode gas is supplied to cathode from outside of the cathode current collector. The anode current collector the cells and the cathode current collectors constitute a pair of independent parallel cells. The anode current collector includes an anode gas passage which is connected to the anode current collector and through which an anode gas is to be provided to the inside of the anode current collector, and an anode current terminal formed at an end of the anode current collector perpendicular to the anode gas flow. Each of the cells includes an anode set in the recessed portion of the anode current collector, an electrolyte plate disposed in contact with an outer surface of the anode and extensive over the recessed portion of the anode current collector, and a cathode disposed in contact with an outer surface of the electrolyte plate. The cathode current collectors is connected to each other at ends disposed opposite to the anode current terminal to form ~ shape, and the cathode current collector is formed at a connection point as a cathode current terminal. The above mentioned molten carbonate fuel cell makes it no longer necessary to use a separator for mechanically separating anode and cathode gases, resulting in remarkable cost down.

Patent CA-2200933-C (CA)
Title: Multistage relay device
Inventor: SHIROKURA YOSHIHIKO
IPC: H04L12/70
Filed: 1997-03-25
Granted: 2000-12-26
Abstract: When a signal is transmitted from an STM line to an ATM relay channel, the signal is compressed to be cell assembled into a cell.  To the contrary, a signal from the ATM relay channel is cell disassembled into separate data and then expanded.  In cases where signals are exchanged between ATM relay channels, a multistage relay device does not repeatedly execute signal compression/expansion to the signal.  Switching for the above operations is achieved, utilizing a signal pattern inserted into audio data.  With this arrangement, an audio one-link operation is established in the environment where an STM and an ARM coexist.  Because compression/expansion processes are not repeatedly conducted, delay in relaying is avoided.

Title: Tower reactors for bioconversion of lignocellulosic material
Inventor: NGUYEN QUANG A
IPC: C12P7/10
Filed: 1997-06-09
Granted: 2000-10-03
Abstract: An apparatus for enzymatic hydrolysis and fermentation of pretreated lignocellulosic material, in the form of a tower bioreactor, having mixers to achieve intermittent mixing of the material. Precise mixing of the material is important for effective heat and mass transfer requirements without damaging or denaturing the enzymes or fermenting microorganisms. The pretreated material, generally in the form of a slurry, is pumped through the bioreactor, either upwards or downwards, and is mixed periodically as it passes through the mixing zones where the mixers are located. For a thin slurry, alternate mixing can be achieved by a pumping loop which also serves as a heat transfer device. Additional heat transfer takes place through the reactor heat transfer jackets.

Abstract: A method for manufacturing a resin-impregnated endless belt structure is carried out on an apparatus (60) having an outer cylinder (66) and an inner cylindrical surface that is coaxial with a smaller radius cylindrical mandrel (64). An endless base structure is disposed with the outer cylinder (66) on the inner cylindrical surface. The cylindrical mandrel, having an inwardly curved nose (68), is then inserted into the outer cylinder (66) forming a nip (70) between the curved nose (68) and the inner cylindrical surface. Polymeric resin is dispensed continuously into the nip (70) while the cylindrical mandrel is gradually moved into the outer cylinder (66). The nose forces the resin into the endless base structure and expels air bubbles while forcing the endless base structure against the inner cylindrical surface. After the polymeric resin is cured, the endless belt structure, having a totally impregnated, air-bubble free endless base structure with a coating on its inner surface, may be obtained upon removal of the apparatus (60).

Title: Method of simulating a photographic camera
Inventor: RIOUX MARC
IPC: G06T15/00
Filed: 1998-10-01
Granted: 2007-09-18
Abstract: Simulating a photographic camera for rendering two-dimensional images of virtual three-dimensional objects enhances flexibility and ease of use of a rendering system. Simulating a photographic camera is performed by determining light from virtual light sources that passes through a lens of the simulated photographic camera having an aperture, focus, and shutter speed and is incident upon the imaging plane within the camera. The method also has application in teaching photography because, in some instances, computer simulation reduces the cost of equipment and consumables.
