20120096873, Apr 26, 2012

Filed:

Oct 20, 2010

Appl. No.:

12/925370

Inventors:

Robert J. Webber - Clinton Corners NY, US
Jean Delmas - Fishkill NY, US

International Classification:

F17C 7/00
F25B 19/00

US Classification:

62 481, 62 511

Abstract:

A fluid control assembly is connected between a cold gas container intended to be operated at deep cryogenic temperatures (e.g., 4K) and a gas reservoir for controlling the flow of fluid between the container and the reservoir. The fluid control assembly may be a passive valve assembly or an electrically controlled valve assembly which controls fluid flow between the reservoir and the container as a function of temperature and/or pressure differentials. The fluid control assembly enables the container to be rapidly cooled by restricting the amount of fluid flow from the reservoir into the container when the container is subjected to thermal cycling within a limited temperature range (e.g., 4K to 11K). The fluid control assembly together with the gas reservoir and the container form a thermal damper which is suited for use in a cryocooling system for producing the cryogenic temperatures (e.g., 4K) to operate superconducting devices which may need to be thermally cycled to remove trapped flux.

Appl. No.:

6/443601

Inventors:

Robert C. Webber - Indian River Shores FL

International Classification:

F01P 1118

US Classification:

123 4127

Abstract:

A coolant system for an internal combustion engine equipped with a radiator, involving the use of a reservoir utilized in a semi-hermetically sealed relationship with the engine and radiator, such that only rarely does additional coolant liquid need be added to the coolant system. This system has the safety of a pressure cap set to release in the pressure range of between 10 and 20 pounds per square inch, but no readmission valve is utilized in the cap, thus excluding unwanted atmospheric air from the coolant system. The reservoir is preferably insulated and of elongate configuration.

Appl. No.:

6/767042

Inventors:

Robert C. Webber - Vero Beach FL

International Classification:

F25B 4106

US Classification:

62511

Abstract:

An expansion device for refrigeration systems replaces capillary tubes and automatic expansion valves. A housing is provided having an inlet tube for connection to the liquid line from the condenser and an outlet tube for connection to the evaporator. The outlet tube has a valve like seat in its inner end and orifice grooves formed in the seat. A steel ball is movably disposed in the housing such that liquid refrigerant during compressor operation forces the ball into the seat thereby forming an expansion orifice between the ball and the seat.

Appl. No.:

6/304832

Inventors:

Robert C. Webber - Indian River Shores FL

International Classification:

F01P 1118

US Classification:

123 4115

Abstract:

An engine pressure-vacuum cooling system with a horizontal coolant storage tank wherein the cooling system is pressurized during engine operation and maintained under vacuum when the engine is inoperative. After filling the system with coolant, during the initial engine warm-up cycles air is purged through a one-way valve and the cooling system thereafter sealed against further entry of air. The storage tank includes a means for confining sludge and other debris to the tank and a means for warning when the system vacuum exceeds a pre-determined level.
