Patent CA-2043373-C (CA)
Inventor: HSU W ERNEST
IPC: B32B7/02
Filed: 1991-05-28
Granted: 1996-05-07
Abstract: A method of producing laminated veneer lumber (LVL) with good dimensional stability, characterized by a particular lay-up of the veneers and the veneers being of at least two different wood species.  The particular veneer lay-up and species arrangement, minimizes the tendency of warping and cracking of the LVL.  All veneers are laid-up in pairs by species with the loose sides of each pair contacting each other and with the species pair sequence from face to core being identical on either side of the center ply or center line.  The veneer tight faces of different species are bonded to one another.  The dimensional stability of the LVL is optionally enhanced by a water repellent, flow promoter and bulking agent that is incorporated into the adhesive before application onto the veneer.  The different species veneers are dried to different moisture contents before lay-up with the denser species being of lower moisture content than the less dense species.

Title: Permanent wire splicing by an explosive joining process
Inventor: BEMENT LAURENCE J
IPC: B23K20/08
Filed: 1991-09-03
Granted: 1994-11-01
Abstract: PERMANENT WIRE SPLICING BY AN EXPLOSIVE JOINING PROCESS Abstract of the Disclosure A method and apparatus for wire splicing using an explosive joining process.  The apparatus consists of a prebent, U-shaped strap of metal 21 that slides over prepositioned wires 22.  A standoff means 23 separates the wires from the strap before joining.   An adhesive 41 holds two ribbon explosives 15 in position centered over the U-shaped strap.   A detonator 24 connects  to  the  ribbon  explosives.    The  process  involves spreading strands of each wire to be joined into a flat plane, alternating  each  strand  in  alignment  to  form  a  mesh-like arrangement with an overlapped area, sliding the strap over the strands of wires, and positioning the standoff means between the two surfaces. The detonator then initiates the ribbon explosives that drive the strap to accomplish a high velocity, angular collision between the mating surfaces.  The collision creates surface melts and collision bonding results in electron-sharing linkups.

Title: Destruction of polychlorinated biphenyls
Inventor: JANIS W JOHN
IPC: A62D3/34

Granted: 1997-09-23
Abstract: Chlorobenzenes present in PCBs as viscosity reducing diluents can be largely removed from the PCBs by fractional distillation without carry over of PCBs into the chlorobenzene rich distillate.  The PCB rich bottoms can be economically destroyed using mixture with sodium dispersion under conditions of temperature, concentration and stirring which result in autocatalytic reaction. Sodium dispersion can be measured for dispensing into the reaction by accumulation under a pressurized gas space in a measuring vessel of predetermined volume until a predetermined pressure is attained.  The pressurized gas is then employed to expel the dispersion from the measuring vessel into the reactor.

Title: Treatment of gas streams
Inventor: WATSON RICHARD WILLIAM
IPC: C01B17/04
Filed: 1993-04-05
Granted: 2002-07-23
Abstract: A part of the hydrogen sulphide content of a feed gas stream comprising hydrogen sulphide is burned by a burner 2 that fires into a furnace 4. The combustion is supported by a stream of oxygen or oxygen-enriched air.      Resulting sulphur dioxide reacts with residual hydrogen sulphide in the furnace 5 to form sulphur vapour. Sulphur is condensed out of the resulting gas mixture in condenser 10. At least part of the sulphur-free gas mixture flows through a reactor 14 in which its sulphur dioxide content is reduced to hydrogen sulphide. Water vapour is removed from the resulting gas stream in a condenser 16. At least part of the gas stream now essentially free of water vapour is recycled to the furnace 4. A purge stream is taken either from immediately downstream of the sulphur condenser (as shown in Figure 1) or from intermediate the water condenser 16 and the furnace 4, or from the furnace 4 and, if desired, subjected to further treatment to remove sulphur-containing gases therefrom.

Title: Engine catalyst aging system and method for aging catalyst
Inventor: NICHOLS ANGELO H
IPC: G01M15/10
Filed: 1994-03-31
Granted: 1996-12-31
Abstract: The present invention provides a method for catalytic aging and a system for catalytic aging. The system modifies the operation of the engine while running in combination with a catalyst, making the engine a programmable gas generator for the catalyst. The present invention allows an operator to alter the operation of the engine by varying the signals to the engine's injectors, thereby altering the exhaust gas of the engine. While the engine is operating under user initiated injector signals, a simulated exhaust gas oxygen signal is provided to the engine control module. This signal results in maintaining the engine in stable operation while operating in an unstable state. In a preferred embodiment additional gases are injected into the exhaust gas being supplied to the catalyst. The system periodically returns all functions to the engine control modules allowing the establishment of new operating parameters for the engine.
