Title: Portable apparatus for chilling draught beverages
Inventor: CHIUSOLO SAM
IPC: B67D1/08
Filed: 2004-12-09
Abstract: The invention provides for a means to chill and dispense a draught beverage with a beverage chiller attached to a beverage storage container. The invention is comprised of an insulated tank, which contains an internal tub, a coil of tubing and a pump. This beverage chiller uses ice and water to chill the beverage. A pump is placed at the bottom of the internal tub and filled to a predetermined level with water. Ice is placed on top of the water and fills the insulated tank. The coiled tubing is placed in the gap between the internal tub and the insulated tank. The pump forces water from inside the internal tub into the bottom of the gap. The water flows over the coil of tubing and over the upper edge of the internal tub where it flows over the ice and returns to the pump. A beverage container is attached with a conduit to the coiled tubing. The beverage flows through the coiled tubing and is cooled by the ice water flowing through the gap between the internal tub and the insulated tank.  The beverage flows from the coiled tubing to a faucet where it is dispensed.

Title: Variable wattage control system
Inventor: FENNEWALD KENNETH J
IPC: H05B1/02
Filed: 2003-08-20
Abstract: A variable wattage control system (10) is disclosed for providing varying wattage levels for a power-receiving device (16). The power-receiving device (16) is operatively associated with a sensing means (18) that communicates with a temperature controller (14) for comparing the sensed temperature with a predetermined set point. If the sensed temperature falls outside the set point, the temperature controller (14) directs a power control means (12) to turn on the power-receiving device (16) at a specific wattage level. The system (10) may include a micro-controller (23) contained in either the temperature controller (14), power controller (12) or a separate module (24) which determines a power output scaling factor based on the percentage of the full line voltage being applied to the power-receiving device and then scaling the power output. The power output scaling factor determines the maximum percentage power to be applied to the power-receiving device such that a single device may be driven at different power levels for various applications.

Title: Generateur electrochimique
Inventor: MERLO LUCA
IPC: H01M8/04
Filed: 2003-11-10
Abstract: L'invention concerne un générateur électrochimique alimenté par des gaz réactifs et notamment, une cellule à combustible alimentée par un gaz contenant de l'hydrogène et par de l'air à pression quasi ambiante. Ce générateur électrochimique est caractérisé par l'asymétrie des baisses de pression localisées dans les canaux distributeurs et collecteurs. Notamment, la baisse de pression concentrée dans les canaux collecteurs est sensiblement plus importante que la baisse de pression concentrée dans les canaux distributeurs. De plus, la pression des zones actives du générateur coïncide sensiblement avec la pression de la zone d'alimentation. Pour obtenir ce résultat, on différencie la conception des canaux distributeurs de la conception des canaux collecteurs, dont la section de passage est diminuée et/ou dont la longueur est augmentée et/ou dont la quantité est réduite.
