Title: High voltage switch operating mechanism
Inventor: EVANS DAVID M
IPC: H01H3/30
Filed: 1979-04-30
Granted: 1982-03-02
Abstract: HIGH VOLTAGE SWITCH OPERATING MECHANISM     Abstract: Disclosed is an improved high voltage switch operating mechanism which utilizes energy stored in a spiral spring to drive high voltage switches from either the open to the closed position or the closed to the open position.  A spiral spring interconnects a rotatably mounted drive lever, which can be rotated to charge the spiral spring, and an output lever, which drives the switch either open or closed when the switch operating mechanism is tripped.  A gearbox assembly reduces the torque required to charge the spiral spring when supplied either manually with a crank or electri-cally through a motor.  The output lever is held in the switch-closed or the switch-opened position by improved first or second output lever latch assemblies, respec-tively, while the drive lever is rotated to charge the spring.  Once the spiral spring is charged, first and second main latches engage the drive lever holding it in a spring charged position.  The switch operating mecha-nism is tripped by releasing first or second output lever latch assemblies, which can be released manually by a single trip handle or by solenoids connected to control circuitry.  When tripped, the spiral spring reacts against the output lever to either open or close the switch, depending on the position of the switch at the initiation of the operation.  After a switching operation is com-pleted, the spring can be recharged for the next opera-tion.  Manual and electrical trip interlock assemblies are provided to prevent the switch operating mechanism from being tripped either manually or electrically while the spiral spring is being recharged either manually or electrically.

Abstract: COPIER JOB RECOVERY SYSTEM               ABSTRACT OF THE DISCLOSURE         Simplexed copy sheets lost during a partially completed pre-collation duplex copying run are automati-cally replaced in proper serial order into the partial copy set in the duplex buffer set tray by lifting the partial buffer copy set stack up with a false tray bottom and inserting replacement (make-up) simplex copies under the buffer set, then the false bottom is lowered and the duplex copying run, is continued, feeding out sheets from the duplex tray with the existing bottom feeder, and feeding the subsequent simplex copies in normally to the top of the buffer set stack.          Thus, the copies in the buffer set do not have to be thrown away or reorganized by the operator when a copier jam occurs.

Abstract: ABSTRACT OF THE DISCLOSURE:           The invention relates to the production of phosphorus-containing anticorrosive pigments with a particle size of at most 20 microns by reacting one or more calcium or magnesium compounds with phosphoric acid or acid alkali metal or ammonium phosphates by intimately mixing an aqueous suspension or solution of the reactants inside a dispersing means rotating at a speed of 3000 to 10 000 rpm. More partic ularly, fine pulverulent calcium and magnesium compounds are converted, with agitation, to-gether with water and, if desired, a water-soluble alkanol to a homogeneous suspension or solution.  The suspension or solution is intimately mixed, inside the dispersing means at 0 to 40° C and in an approximately stoichiometric ratio, with the phosphoric acid or acid phosphate solution.  Resulting and precipitated pigment is separated and dried under mild conditions while maintaining its content of water of crystallization.  The anticorrosive pigment is comprised of a homogeneous mixture and/or mixed crystals of which 10 to 95 mol% is calcium hydrogen phosphate dihydrate, the balance being magnesium hydrogen phosphate trihydrate.  An at least 55 weight% proportion consists of particles with a size of up to 5 microns with a BET-surface of at least 1m2/g.

Abstract: ABSTRACT OF THE DISCLOSURE A plural component dispensing system includes supplies which fur-nish first and second components, such as a resin and catalyst, under press-ure to a hand-held dispensing device having first and second valves, respec-tively.  First and second passageways lead from the first and second valves to a mixing chamber in which the components are mixed, and from which the components are ejected.  Upon mixing, the components are subject to increas-ing viscosity and hardening.  A third valve controls flow of a purging medium from a supply of such a medium to the mixing chamber.  A sensing device, such as a pressure sensor, senses the orientation of either/or both of the first and second valves.  When the first and second valves are moved to positions to halt the flow of the two components, the sensing device generates a signal to start a first timing device.  At the end of a predetermined time interval, the first timing device generates a signal which opens the third valve, per-mitting the purging medium to flow into the chamber and purge the mixed com-ponents from the chamber before they harden,  The first timer also starts a second timer.  At the end of a second predetermined time interval, the second timer generates a signal which closes the third valve, halting the flow of the purging medium.

A keying circuit for television, in the form of a special effect generator or a chroma-keying circuit. In order to generate a keying signal which does not cause flicker phenomena in an interlaced television picture when there is a great contrast in the region of a signal switch-over between two video signals in response to the keying signal, the circuit comprises a signal delay device and a signal combining circuit for the binary keying signal which occurs undelayed and delayed. The signal delay device has delay times of a field period minus and plus one line period and of one and two line periods, respectively. This results in a gradually changing keying signal there, where the flicker phenomenon in the interlaced television picture might occur.

Abstract: ABSTRACT A system for producing a velocity pattern for a vehicle such as an elevator car which must be brought smoothly to a stop accurately aligned with a desired one of a number of stations.          The distance between the vehicle and the station at which a stop is required (target distance) is expressed in digital form, and is processed electronically to produce a velocity pattern which results in constant deceleration of the vehicle during the entire approach except for an initial build-up to, and a final tapering off from, the constant deceleration.  A single adjustment for deceleration rate automatically adjusts the slowdown distance to the correct value to suit the selected deceleration rate.          The calculation is done repetitively at high speed to minimize any lag between the diminishing target distance and the corresponding velocity pattern.  Further adjustments permit control of the final tapering off from constant deceleration, with the slowdown distance automatically adjusted to suite these adjustments also.
