Title: Device for the correlation of optical beams
Inventor: GREGO GIORGIO
IPC: G02F3/00
Filed: 1990-03-23
Abstract: ABSTRACT        Correlation is obtained between optical beams having spatially modulated intensities by means of an active-glass window, one side of which is illuminated simultaneously by reading and pumping beams using at least one semi-transparent mirror to combine the beams.     The reading beam is of radiation with a wavelength equal to that of the transition between intermediate and fundamental energy levels of the material of the window, and the pump beam is of radiation with a wavelength corresponding to the highest energy level of the material forming the active glass.  The light beam leaving the window is modulated with a correlation between the reading and pumping beams.

Patent CA-2032594-A1 (CA)
Title: Fastener driving tool
Inventor: KERRIGAN JAMES E
IPC: B25C1/06
Filed: 1990-12-18
Abstract: FASTENER DRIVING TOOL Abstract of the Disclosure A lightweight fastener driving tool capable of being battery powered utilizes a low cost fastener driving ram or blade that is normally located in a nip defined between a motor driven flywheel and an idler wheel.  Upon the actuation of a trigger operated timing circuit, a solenoid is energized.  The solenoid controls a toggle mechanism to adjust the position of the idler wheel with respect to the flywheel so as to force the blade against the flywheel and thereby to close the nip for a sufficient amount of time to initiate the driving of the blade downwardly through the nip.  The timing circuit deenergizes the solenoid prior to the time that the blade exits the nip but the toggle mechanism maintains the idler wheel against the blade such that the blade continues to be driven by the flywheel.  When the top of the blade exits the nip, the idler wheel can move towards the flywheel and the toggle mechanism releases the idler wheel so that the nip is open.  With the nip open and the down-ward movement of the blade halted by a lower bumper, the blade is permitted to be raised to its non-actuated position by a double torsion spring.

Abstract: SECONDARY FUEL MODULATING VALVE                  Abstract of the Disclosure A valve for controlling the flow of secondary fuel to a  turbo-charged  diesel  engine.    The valve  incorporates  a cylinder, a first inlet port which couples the cylinder to a secondary fuel reservoir, a second inlet port which couples the cylinder to the engine's turbo-charger, a discharge port which couples the cylinder to a secondary fuel inlet of the engine, and a piston which is slidably displaceable within the cylinder to controllably open and close the discharge port in response to changes in the turbo-charger's boost pressure.  The piston moves between a closed position in which the piston blocks secondary fuel flow from the first inlet port to the discharge port, a first range of open positions  in which the piston  allows progressively increasing amounts of secondary fuel to flow from the first inlet port to the discharge port, and a second range of open positions in which the piston allows progressively decreasing amounts of secondary fuel to flow from the first inlet port to the discharge port.
