Patent CA-2062589-A1 (CA)
Title: Air separation
Inventor: RATHBONE THOMAS
IPC: F01D15/10
Filed: 1992-03-10
Abstract: ABSTRACT AIR SEPARTION            Air is taken from the air compressor 4 of a gas turbine 2 including in addition to the compressor 4 a combustion chamber 6 and an expansion turbine 8.  The gas turbine 2 drives an alternator 10.  The air taken from the compressor 4 is cooled in heat exchanger 12 to remove heat of compression therefrom.  The air is separated in an air separation plant 14 into oxygen and nitrogen.            A stream of oxygen is withdrawn from the plant 14 and used in a blast furnace 20 in which iron is made.  The off-gas from the blast furnace 20 is a low grade gaseous fuel.  It is compressed in compressor 24 which has interstage cooling to remove at least some of the heat of compression. The compressed fuel gas is passed through the heat exchanger 12 countercurrently to the air stream.  The resulting pre-heated fuel gas flows into the combustion chamber 6 of the gas turbine 2 and is burned therein to generate gaseous combustion products that are expanded in the turbine 8.  A nitrogen stream is withdrawn in the air separation plant 14.  A part of the nitrogen stream is introduced into the combustion chamber 6 and is expanded with the aforesaid gaseous combustion products, while another part is expanded in a separate expansion turbine 34.

Abstract: The  bandwidth  of  the  data  transfer  among  a main memory and snoopy caches is improved by solving the bus neck in a multiprocessor system using a snoopy cache technique. Shared bus coupling is employed for an address/command bus requiring bus snoop whereas multiple data paths coupled by an interconnection network are used for the data bus not requiring bus snoop.   The multiple data paths reflect the order of the snoopy operations on the order of data transfer such as to maintain data consistency among the caches.
Patent CA-2063537-A1 (CA)
Inventor: NELSON WILLIAM G
IPC: F25B49/02
Filed: 1992-03-19
Abstract: A household type refrigerator has a refrigeration system  including a  subcooling flow control  valve placed between the outlet of the condenser and the inlet to the capillary tube.  The subcooling flow control valve utilizes a sealed capsule of refrigerant which operates to open and close a valve to modulate the flow from the condenser to the capillary tube to insure only that a subcooled liquid enters the capillary.  The valve is mounted vertically next to the compressor and has the inlet line to the valve secured in heat conducting contact to the return line to the compressor for faster opening and closing response while the discharge side of the valve has a chamber filled with a plug to minimize the volume of refrigerant remaining between the closed valve and the entrance to the capillary when the compressor is on the off cycle.

Patent CA-2095083-A1 (CA)
Inventor: CHMIELEWSKI KONRAD G
IPC: F24H3/08
Filed: 1993-04-28
Abstract: A low NOx burner assembly of a fuel-fired heating appliance is supplied with an air/fuel mixture having a substantially less than stoichiometric  air-to-fuel  ratio.    The  air-rich  mixture  is partially combusted to create primary combustion products disposed within an open inlet portion of a combustor structure having a catalytic converter operatively positioned within an open outlet portion thereof spaced apart from its open inlet portion.  A flow of  aspirating air is  introduced into the combustor structure between the inlet and outlet portions thereof.  The aspirating air mixes with the primary combustion products, cools them, and flows with  them  outwardly  through  the  catalytic  converter.    This essentially completes the combustion of the remaining fuel within the  cooled  primary  combustion  products,  and  does  so  at  a temperature not appreciably greater than the initial combustion flame temperature to thereby substantially reduce NOx emissions without the use of flame quenching techniques.  The burner assembly is representatively illustrated as being incorporated in several types of forced air heating furnaces, but could also be used in other types of fuel-fired heating appliances such as boilers and water heaters.
