Patent number: 6749901Abstract: A condenser that is to be brazed in a radiant energy oven has a significant, localized mass differential which would, without further treatment, create a significant temperature differential across the condenser in the braze oven. This is compensated for, in the method of the invention, by thermally spraying onto the surface of the higher mass portion a rough surface layer of a compatible material that increases the emissivity of that portion sufficiently, relative to the rest of the condenser, to decrease the temperature differential that would otherwise occur.Type: GrantFiled: August 24, 2000Date of Patent: June 15, 2004Assignee: Delphi Technologies, Inc.Inventors: Kunal Ghosh, Michael Czajkowski, Frank Joseph Leitch, Christopher Alfred Fuller, Lorraine Anders

Patent number: 5768912Abstract: A process for producing a liquefied natural product such as LNG is described where a single phase nitrogen refrigerant is used in such a way that the refrigerant stream (10) is divided into at least two separate portions (12, 14) which are passed through separate turbo-expanders (106, 108) before being admitted to separate heat exchangers (103, 104) so that the warming curve of the refrigerant more closely matches the cooling curve of the product being liquefied so as to minimize thermodynamic inefficiencies and hence power requirements involved in operation of the method.Type: GrantFiled: January 21, 1997Date of Patent: June 23, 1998Inventor: Christopher Alfred Dubar
