Patent CA-2146052-A1 (CA)
Title: Optical scanning system
Inventor: GANGSTEAD MERVIN L
IPC: G11B7/004
Filed: 1995-03-31
Abstract: OPTICAL SCANNING SYSTEM ABSTRACT     An optical scanning system wherein a moving cylinder supporting a segment of recording media on its  inner surface is axially moved over a pair of fixed cylinders. A slit is provided between the fixed cylinders, and a light beam is radially scanned by the system through and along the slit to scan the surface of the supported segment of media as the moving cylinder moves in an axial direction over the fixed cylinders and across the slit.  A pressure source provides air to the moving cylinder,  with the supplied air expelled from an inner surface of the moving cylinder  against the  fixed cylinders  to  form  an air bearing. Air is also expelled into the area between the fixed and moving cylinders to float the media therein during media advancement.  A vacuum source is also provided to draw air through the moving cylinder from the area between the fixed and moving cylinders holding the media against the inner surface of the moving cylinder while the media is being scanned by the light beam.

Title: Process for wave soldering components on a printed circuit board in a temperature controlled non-oxidizing atmosphere
Inventor: MCKEAN KEVIN P
IPC: B23K1/08
Filed: 1995-04-07
Abstract: Abstract of the Disclosure The present invention relates to a wave soldering process wherein an inert gas atmosphere is injected inside the wave soldering machine,  said inert gas atmosphere having a temperature which might be controlled.  Particu-larly,  the  atmosphere  can  be  heated  at  the  same  or different temperatures before injection, for example in the preheating zones, in the machine.  The atmosphere can also be cooled (or injected at ambient temperature) e.g. in the cooling zone.  Various atmospheres can be used (similar or different  from  one  zone  to  another).    The  thermal efficiency of the heat transfer between the atmosphere and the printed circuit boards is thus greatly enhanced, which means less solder defects, higher components density and decrease of energy consumption and inert gas flow rate.

Title: Performance enhanced gas turbine powerplants
Inventor: JANES CLARENCE W
IPC: F02C7/224
Filed: 1994-10-18
Abstract: A gas turbine driven powerplant (10) having one or more compressors (20, 22) for producing a down stream air flow, a compressor heat exchanger (34) positioned down stream of the compressors (20, 22) followed by a side stream flow coolant line (50), a regenerator (58) positioned down stream of the heat exchanger (34) and side stream coolant line (50), a combustor (48) positioned down stream of the regenerator (58), one or more turbines (24, 28) positioned down stream of the combustor (48) and mechanically coupled to the compressors (20, 22), and a power turbine (32) positioned down stream of the turbines (24, 28). Combustible effluent flows through heat exchanger (34) and to combustor (48), and air discharged from the compressors (20, 22) flows through heat exchanger (34) and to coolant line (50) and regenerator (58). Heat is transferred from the compressor discharge air to the combustible effluent, thereby producing cooling air and heating the combustible effluent. Heat exchanger (34) can be a heat exchanger or a methane/steam reformer which produces a hydrogen-rich, low NOx, steam diluted combustible effluent. In alternative embodiments, power output is augmented by injecting cooled compressed air directly into the combustor (48) to increase the mass flow through the turbines (24, 28, 32), and exhaust heat is recuperated with a counter-current flow of combustible and water, or water and air, in a conventional once-through heat recovery unit (118). In further embodiments, a small portion of the cool air is combined with the recuperation water in the heat recovery unit (118) to allow vaporization of the water throughout the initial portion of the heat exchange path and form a two-phased feed of water and air to the combustor (48). Additionally, in all embodiments a portion of the cooled compressed air can be processed by a compressor/expander for providing coolant to the turbines, compressors, and auxiliary equipment.
