Patent CA-2035682-A1 (CA)
Inventor: PELKEY MARK J
IPC: F17D1/20
Filed: 1991-02-05
Abstract: The invention relates to a gas pressure safety device used in the natural gas distribution systems leading to homes or other customers. This safety device is connected to a gas venting device that allows excess gas to exit therefrom. The safety device is made up of a needle valve, a pressure sensing pilot and a spring-diaphragm actuator. The needle valve is used to restrict the rate of gas flow into the actuator to a rate less than that that can be vented by the pressure sensing pilot. When an excess pressure is generated in the distribution system, the pressure sensing pilot senses when to exhaust the excess gas through the actuator and out of the gas venting device to the atmosphere.

Title: Method and apparatus for passive refrigerant retrieval and storage
Inventor: SQUIRES DAVID C
IPC: F25B45/00
Filed: 1991-09-27
Abstract: ABSTRACT OF THE INVENTION         A passive refrigerant retrieval and storage apparatus is shown for retrieving refrigerant from a cooling system prior to  servicing  the  cooling  system.   The  passive  apparatus includes a coil collector tube within an insulated housing with an outlet from the collector tube passing through a metering valve into the housing.  The collector tube is connected to the condenser outlet of a cooling system and the system compressor operated  to  pump  pressurized  liquid  refrigerant  into  the collector tube.   A  small  portion  of  the  refrigerant  is discharged  through  the  metering  valve  into  the  apparatus housing where it is evaporated and causes extreme subcooling to the refrigerant in the collector tube.  A return line from the housing  to  the  inlet  side  of  the  compressor  returns  the evaporated refrigerant to the cooling system.   Gradually the cooling  system  is  starved for  refrigerant  such  that  the pressures in both the high pressure side and low pressure side of  the  cooling  system  gradually  decrease,  decreasing  the pressure of refrigerant within the collector tube and housing of the retrieval apparatus such that the liquid will no longer evaporate, trapping the refrigerant in the retrieval apparatus.
