Publication number: 20020148502Abstract: A gas feed device for detecting trouble in a gas pressure sensor fitted to the gas feed device. The presence of trouble in pressure sensors 52 to 58 is determined according to whether or not gas pressure values detected by the pressure sensors 52 to 58 fitted to branch pipes 32 to 38 is within an allowable range when stop valves 42 to 48 fitted to the branch pipes 32 to 38 connected to the access ports of hydrogen absorbing alloy tanks 22 to 28 are fully opened from their fully closed state. When the gas feed device 20 is mounted on a vehicle, no special operation is required for trouble detection because the trouble in the pressure sensors 52 to 58 can be detected by fully opening the fully closed stop valves 42 to 48 when the vehicle is started. And normally the trouble can be judged by the mounted equipment.Type: ApplicationFiled: March 13, 2002Publication date: October 17, 2002Inventor: Nobuo Fujita

Patent number: 6431201Abstract: A water management system for a motor vehicle in which water is collected from the condenser (1) of the air-conditioning unit, stored in a master water tank (5) and distributed therefrom to the battery (15), screen wash jet (27) and radiator (37). The vehicle owner is thus spared the inconvenience of regularly checking and topping up the water supply for these items. The risk of breakdown is also reduced. In another aspect of the invention, a wet battery (15) incorporates a plurality of float valves (75) for regulating the fluid level in respective cells (61, 63) of the battery. Water is passed through a common channel (23) into which the float valves (75) open when the fluid level is below a preset limit. The battery fluid is thereby automatically kept at the required level for optimum performance and lifetime of the battery.Type: GrantFiled: December 22, 2000Date of Patent: August 13, 2002Inventor: Chin Lye Chau

Patent number: 6418962Abstract: A compressed gas vehicle fuel storage system comprised of a plurality of compressed gas pressure cells supported by shock-absorbing bumpers positioned within a low cost, shape-conforming container. The container is dimensioned relative to the compressed gas pressure cells whereby a radial air gap surrounds each compressed gas pressure cell. The radial air gap allows pressure-induced expansion of the pressure cells without resulting in the application of pressure to adjacent pressure cells or physical pressure to the container. The pressure cells are interconnected by a gas control assembly including a thermally activated pressure relief device, a manual safety shut-off valve, and means for connecting the fuel storage system to a vehicle power source and a refueling adapter. The gas control assembly is enclosed by a protective cover attached to the container. The system is attached to the vehicle with straps to enable the chassis to deform as intended in a high-speed collision.Type: GrantFiled: October 27, 1999Date of Patent: July 16, 2002Assignee: The Johns Hopkins UniversityInventors: John J. Wozniak, Paul D. Wienhold, Dale B. Tiller

Patent number: 6418961Abstract: A water supply manifold can be manufactured easily and inexpensively while simultaneously providing an improved connection of manifold components to one another. The water supply manifold, or at least each section thereof, includes (1) a header tube that is configured to extend longitudinally along a support surface such as a shelf and (2) fittings that are mounted on the header tube in a spaced-apart relationship relative to one another. In a preferred embodiment in which the water supply manifold is intended for use in an animal water supply system, two opposed fittings may be provided on opposite sides of the header tube at each water supply location so as to permit two rows of cages to be mounted back-to-back on each shelf of a cage and rack system. In this case, a single supply tube may extend completely through the header tube at each water supply location and receive a respective fitting at each of two outlet ends thereof.Type: GrantFiled: April 18, 2000Date of Patent: July 16, 2002Assignee: Edstrom Industries, Inc.Inventor: William E. Edstrom, Sr.

Patent number: 6336468Abstract: A supply tube isolation system for use with a chemical delivery system includes a feedback tube connected between the manifold and each of the supply tubes connected between the chemical supply containers and the chemical pumps of the chemical delivery system. A controllable valve means is provided at or near the junction of the feedback tube and the supply tube so as to effectively segment the supply tube into first and second portions, where the first supply tube portion is that which is connected between the valve means and the manifold, and the second tube portion is that which is connected between the valve means and the chemical supply container. During delivery of the chemical to one or more destinations within the delivery system, the valve means is positioned so as to close the feedback tube and connect the first and second portions of the supply tube.Type: GrantFiled: January 30, 1998Date of Patent: January 8, 2002Assignee: Diverseylever, Inc.Inventor: Robert G. Cords

Patent number: 6314978Abstract: To produce a high pressure stream of fluid, such as propellant, the fluid is transfered from a low pressure reservoir into a plurality of intermediate storage tanks, in which the fluid is pressurized. The fluid is drained from the storage tanks to an outlet in sequence. While one pressurized storage tank in a three pressurized tank system is being drained, the most recently drained one of the storage tanks is being vented, and still another of the storage tanks is being filled or replenished with fluid, as the case may be, from the low pressure reservior.Type: GrantFiled: February 21, 1996Date of Patent: November 13, 2001Assignee: McDonnell Douglas CorporationInventors: Mark Eric Lanning, James B. Blackmon, Jr.

Patent number: 6279612Abstract: An auxiliary fuel tank system includes a permanent pressure tank for natural gas or propane is mounted on a vehicle such as a fork lift truck. The auxiliary tank is connected through fuel lines to a replaceable portable tank which supplies fuel to the auxiliary tank through check valves and a valve mechanism which may be turned on and off. The auxiliary tank is filled upon initial attachment of the portable tank to the fuel line for the truck. After filling the auxiliary tank, the valve mechanism is closed only to be reopened upon exhaustion of fuel from the portable tank. Fuel lines connect the respective tanks to the engine thereby permitting operation of the engine, even upon exhaustion of fuel from the portable, replaceable tank.Type: GrantFiled: August 10, 1999Date of Patent: August 28, 2001Assignee: Spare Tank Co., Inc.Inventor: Mitchell W. Warth
