Title: Multi-beam laser diode beam separation control
Inventor: GUERIN JEAN-MICHEL
IPC: H04N1/191
Filed: 1993-04-07
Abstract: ABSTRACT   A multi-beam raster output scanner is disclosed which utilizes a deflection wedge for modifying the beam separation independent of the spot size to generatea desired relationship between spot separation and spot size. The beam separation can be modified by moving the deflection wedge back and forth. Depending on the distance between the deflection wedge and a spot size control aperture, the beamseparation varies. In this invention, as in the prior art, the spot size can be modified by changing the size of the control aperture, but to avoid the loss of intensity, the size of the control aperture will be changed only for fine adjustments to achieve the proper spot size.

Title: Electronic identification system with anti-tampering protection
Inventor: AUSTIN KENNETH
IPC: B60R25/00
Filed: 1993-08-27
Abstract: ABSTRACT Title: Electronic identification system with anti-tampering protection An electronic identity device is proposed for securing to equipment, especially a vehicle, and has anti-tampering protection. The device is intended to prevent the identity of a vehicle being changed unknowingly. The device comprises at least a control processor having a memory containing accessible data unique to the equipment (for example a vehicle chassis number and/or engine number), and preferably a slave processor. The device also comprises means generating a security signal and means for detecting any lack of integrity of the security signal to generate a tamper warning signal. The security signal is generated repeatedly irrespective of whether the vehicle is in operation. More particularly, the security signal is transmitted over a communication link in the form of fibre optic cabling which is adhered to the equipment. Any attempt to remove the electronic device or tamper with the cabling will corrupt the security signal and therefore generate a tamper warning signal.

Patent CA-2114094-A1 (CA)
Inventor: GOTTEMOLLER PAUL
IPC: F02B39/12
Filed: 1994-01-24
Abstract: A two cycle, preferably diesel, engine has a turbocharger with an exhaust driven turbine and supplemental mechanical drive maintaining a fixed minimum turbine/engine speed ratio with fuel efficient freewheeling (fully exhaust sustained) turbine operation at higher speeds and loads.  A turbo boost system provides freewheeling turbine operation at intermediate speeds where it might or will not otherwise occur.  When an intermediate speed is reached at which freewheeling can be sustained but is not occurring, the system 1) temporarily increases engine speed to a predetermined higher level to accelerate the turbine and increase engine air flow, 2) increases engine fuel input to a higher level capable of sustaining freewheeling, and 3) reduces engine speed to the selected intermediate speed while maintaining a fuel input level adequate to maintain turbine freewheeling. Methods and means for providing and controlling intermediate speed freewheeling operation are disclosed.

Inventor: SCARBOROUGH VICTORIA D
IPC: B27K3/34
Filed: 1994-04-13
Abstract: There is provided a water based water repellent coating composition, method of making and method of use.  The coating composition comprises an emulsion having water as the continuous phase and, as the discontinuous phase, droplets of a nonvolatile organic water repellent composition, the emulsion containg an emulsion stabilizing amount of a hydrophobically modified polyacrylic acid polymer wherein the viscosity of the emulsion is less than about 100 Cps and the particle size of the droplets is less than about 50 microns.  The relatively low viscosity and small particle size provides for easy application and excellent penetration into porous substrates.  The process of making the compositions involves the making of a conventional emulsion of this type and then high kinetic energy processing so as to produce the desired viscosity and particle size.  The method of use involves the application of the composition to a substrate followed by evaporation of the water and any volatile components from the composition.

Patent CA-2130747-A1 (CA)
Inventor: O'BRIEN JEFFREY J
IPC: B32B7/12
Filed: 1993-03-04
Abstract: A base thermoplastic film has a coextruded or coated heat seal layer formed from a polymer blend which provides good peel-apart heat seals. When the film is sealed to itself, the seal opens by separation at the original seal surface without film tear, or by delamination of the sealant material from the primary HDPE film substrate without the formation of strands extending between the two base film. The heat seal layer which may be on one or both sides of the base layer comprises a ternary blend of a random ethylene-propylene copolymer, a butene polymer and a low density polyethylene. The films are cast, and oriented in the solid state up to about two times in the machine direction and six times or more in the transverse direction to give films having good dead-fold and water vapor transmission rate characteristics making them highly suited for packaging, particularly for dry foods.

Title: Engine cooling system with thermostatic
Inventor: ROTH DAVID B
IPC: F01P5/12
Filed: 1994-08-25
Abstract: Abstract of the Disclosure An improved cooling system for an internal combustion engine in an automotive vehicle which utilizes recirculating liquid coolant and provides an  initial  engine warm-up flow circuit extending: from a coolant pump, through cooling passages in the cylinder head, through a heat exchanger used to warm a passenger compartment, and back to the pump whereby a temperature responsive flow control valve or thermostat prohibits a flow of coolant from the cylinder head to cooling passages in the engine block which provides adequate cooling of the upper surfaces of the combustion chamber which are formed by the cylinder head while promoting a relatively rapid heating of the surfaces of the engine cylinders formed by the block.  After the warm-up period, the thermostat opens to permit coolant flow into a down-flow passage between the cylinder head coolant passages and the engine block coolant passages resulting in a normal engine cooling circuit extending: from the coolant pump, through the cylinder head cooling passages, then through the engine block cooling passages, through a vehicle radiator, and back to the coolant pump.   The improved cooling system actively cools the upper surfaces of the combustion chamber formed by the cylinder head both during an engine warm-up period and during normal engine operation which promotes complete combustion of the fuel and inhibits knock and pre-ignition.  Also, since coolant warmed in the cylinder head coolant passages is directed to the passenger compartment heater, the heater more quickly provides heated air for the passenger compartment and for window defrosting.  After the warm-up mode, the temperature of the engine is regulated by exchange of  excess  engine  heat to  ambient  by  the  vehicle radiator.
