Patent CA-1057822-A (CA)
Inventor: GREEN SAM J
IPC: H01T13/58

Abstract: ABSTRACT OF THE DISCLOSURE    An improved high voltage pulse power supply for a spark plug test fixture.  AC line voltage is applied through a voltage step-down transformer, a half wave rectifier and an electronic switch to the primary winding of a conventional ignition coil.  During the rise time of positive half cycles, the rectified voltage is applied through the electronic switch to the igni-tion coil primary.  As the positive half cycle begins to fall towards the zero crossover, the electronic switch is opened.  The magnetic field collapse in the ignition coil produces a high voltage negative pulse which is applied to a spark plug under test.  The peak voltage of the negative pulse is ad-justed by controlling the peak current in the ignition coil primary.

Abstract: CABLE HANDLING ABSTRACT OF THE DISCLOSURE A cable handling mechanism for an X-ray tomographic scanner having a rotor assembly for making a scan of about two revolutions and then rewinding to an initial position includes two axially displaced drums.  One drum is attached to the rotor housing and rotates with it; the other is fixed to the stationary structure.  A pulley carrier between the two drums is rotatable about the same axis and carries large and small idler pulleys. At one extreme end position one or more individual cables inside a loose-fiting flexible tube are wound around the rotating drum for two turns, around the large idler pulley and in the opposite direction around the fixed drum for a single turn, and a control cable is attached to the rotating drum wound in a direction opposite to that of the flexible tube but for only one turn, around the small idler pulley and in the opposite direction on the fixed drum for two turns to which the other end of the control cable is attached.

Abstract: AIR SEPARATOR METHOD AND APPARATUS        Abstract of the Disclosure A rotating separator removes air coating from pigmented paper coating liquid stock.  The separator employs a cylindrical tank which is mounted for rotation about a vertical axis.  The separator is operated in a filled con-dition and an air laden or froth fraction is removed from a radially central region of the tank at the top of the tank, while a non-rotating pickup receives air free coating from a region adjacent the wall of the tank near the tank bottom.      The method of treating and applying such a coating includes the steps of pumping an air laden coating into a centrifugal separator while maintaining the separator in a filled condition, removing an air froth from the separator for return to the supply tank, and delivering a substantially air free coating directly to the inlet of a control without the imposition of any intermediate pumping apparatus.  The centrifugal pumping action of the separator supplements the pressure head on the coating material.

Abstract: ABSTRACT OF THE DISCLOSURE A process is provided for preparing adhesive repellent coatings. The process includes applying to the surface to be rendered adhesive repel-lent a mixture of four components.  The first is a diorganopolysiloxane having terminal Si-bonded vinyl groups, but which is otherwise free of ali-phatic multiple bonds.  The second is an organopolysiloxane having at least 3-Si-bonded hydrogen atoms per molecule.  The third is a vinylsiloxane platinum complex which is essentially free of halogen.  The fourth is a compound which retards or delays the addition of Si-bonded hydrogen to aliphatic multiple bonds at room temperature.  That fourth compound may be. an organic silicon compound or an organosilicon compound having a boil-ing point of at least 25°C at 760 mm Hg (absolute) and at least one ali-phatic triple bond and are free of nitrogen and phosphorous atoms as well as carboxyl group which are in an alpha position in relation to a carbon atom from which aliphatic triple bond originates, as well as mereapte and carboxyl groups.  The process then includes the step of crosslinking the diorganopolysiloxane.  The composition used in the process has a longer pot life.  The adhesive repellent coatings so formed exhibit improved mechanical strength.

Abstract: TO ALL WHOM IT MAY CONCERN:          BE IT KNOWN that I, WERNER DIERMAYER, a citizen of the United States of America, residing in the City of Lafayette, County of Contra Costa, State of California, have invented certain new and useful improvements in DRAFT CONTROL ARRANGEMENT FOR COMBUSTION APPARATUS of which the following is the specification.                Abstract of the Disclosure The combustion gases of a burner in a heating furnace are discharged to a vent through a draft hood having three ports.  The first and second ports com-municate with the furnace and the vent respectively and define a first flow path for combustion gases through the chamber of the hood.  The third port is open to the ambient atmosphere and defines a second flow path for dilution air through the chamber.  Separate temperature responsive, bimetallic elements sense the temperatures in the two paths and cause a vent damper to be moved toward and away from a position in which it closes the second port in response to the sensed temperatures to minimize the flow of dilution air.  In a modified embodiment the draft hood is vertically elongate with the bimetallic elements positioned in a zone filling with hot products of combustion for minimizing the flow of dilution air and minimizing spillage of products of combustion during start-up and sudden changes in draft.

Abstract: A B S T R A C T           A control system for a continuously operating press for the production of chipboard, laminated moulding material and the like has two endlessly circulating moulding belts which advance facing each other in a press moulding section and between which the starting material can be com-pressed in the press moulding portion.  Each belt has a separate drive one of the drives being the leading drive and having a speed regulator for maintain-ing a constant speed.  A torque regulator compares the torque of the drive functioning as the leading drive with the torque of the second drive and regulates so that the torques constantly maintain an adjustable ratio between them over the entire torque range.  A second speed regulator is associated with the belt drive which does not function as the leading drive, and is set to a value higher (e.g. by 1% to 10%) than that of the speed regulator of the leading drive and responds to the speed regulator of the leading drive while the speed ratio remains constant.  The torques can be regulated so that they are identical to within approximately ? 10%.

Title: Inversion brake valve and system therefor

Granted: 1979-05-15
Abstract: Abstract A pneumatic brake system employing dual-diaphragm, spring-actuated, air-released brake actuators is provided with an inversion valve which, in the event of a brake system failure, prevents the brakes from being automatically applied while permitting controlled brake application by releasing compressed air from each actuator's spring chamber in an in-verse ratio to that normally supplied from the system by the operator applied brake valve thus permitting a controlled spring brake application.  The valve employs first and second pressure responsive pistons with associated valve seats to maintain the actuator springs compressed with air at supply pressure when the vehicle is normally operated.  The air at supply pressure in each actuator's spring chamber is automati-cally ported to a lower pressure through the valve when a system failure occurs and prior to brake application to insure fast response time of the spring actuated brake.
