Abstract: ABSTRACT OF THE DISCLOSURE         Substrates which are susceptible to corrosion by the action of chemical agents in gas-containing and/or gas-generating media are rendered resistant to said corrosion by the application thereto of a coating of a gas-permeable elastomeric or plastic material, and providing for means of escape of gases permeating the coating, thereby maintaining the adhesion of the coating to the substrate.  The preferred coating is an RTV silicone elastomer of a particular type as exemplified by "Canadian General Electric RTV 108".          Preferably the coating is applied first to a porous backing material such as woven glass cloth, and then t he laminate of coating and porous backing material is adhesively secured to the substrate.  The invention has particular application to the lining of electrolytic cells, cell tanks, submerged bus-work, and associated equipment (except electrodes); and also to the lining of chemical process vessels, equipment, piping, valves and the like for use in the production and handling of chemicals.

Abstract: Abstract of the Disclosure The present invention relates to a wire stripping device.  A pair of jaws mount a first pair of cutting blades for movement towards each other substantially in a plane to cut insulation.  A yoke with spring arms mounts a second pair of cutting blades at right angles to the first blades for movement towards each other substantially in the same plane as the first blades as well as for movement axially when an adjustable stop is reached.  A first handle, through linkage, moves the jaws, and the jaws by cam ears move the yoke arms whereby all the blades are caused to move towards a central axis during the insulation cutting action.  The second handle connected by a push bar to the yoke moves the yoke axially to separate the first and second blade means when a spring bias is overcome when the stop is reached.

Title: Fly run-out correction for vehicle  wheel alignment
Inventor: CHANG ANDREW K
IPC: G01B11/275
Filed: 1978-11-15
Granted: 1982-04-27
Abstract: Abstract of the Disclosure In a wheel alignment system, the error caused by run-out of the axis of a fixture that is clamped to the wheel and mounts gravity stabilized inclination sensors is corrected by continuously providing fixture axis inclination signals during rotation of the wheel through at least 360° from any random starting position.          Maximum and minimum comparator devices continuously receive these signals, and the signals are also pre-sented to associated maximum and minimum storage latch devices connected to their respective comparators.  The maximum signal comparator provides a load signal to its storage device whenever the signal received by the comparator from a sensor is greater than that previously received by the maximum storage device whereby the maximum signal storage device stores the maximum fixture axis inclination signal.  The minimum comparator device provides a load signal whenever the signal received from a sensor is less than that previously received by the associated minimum signal storage device whereby the minimum storage device stores the minimum inclina-tion signal,  A first adder adds the maximum and minimum signals and divides them by 2 to provide a preliminary alignment signal proportional to the actual angular inclination of the wheel axis in a selected alignment plane, and the perliminary alignment signal is sub-tracted from an intermediate inclination signal from the sensor that represents the inclination of the fixture axis at the wheel stopped position to provide a run-out error signal proportional to that portion of the total -1a-angular run-out of the fixture axis that is present in a selected alignment plane at the wheel stopped position.          When the wheel is set down, a final inclination signal is received from the sensor means and the run-out error signal is subtracted therefrom to provide an inclination signal that represents the true wheel axis inclination in a selected aligmnent plane corrected for run-out error, and this signal is displayed for wheel alignment pur-poses.  The sensors measure run-out errors in both the camber and toe planes and provide separate displays for the alignment in both planes.  The maximum and minimum inclination signals are provided by maximum and minimum digital comparator and signal storage devices as well as by digital adding and other devices with suitable converters for supplying the digital devices with 8 bits of binary digital information.                   -1b-

Abstract: ABSTRACT OF THE DISCLOSURE A cyclic-action buoyant toy has no moving parts.  The toy floats in water in a first, horizontal position with a port below water level to admit water into a cavity within the toy, while a siphon connected to a drain operates whenever the toy has admitted enough water to assume a second, angled position.  The siphon removes water at a faster rate then the port admits water, restoring the toy to the first position, stopping the siphon, and restarting the cyclic action.  One embodiment uses a single-ended siphon, while a faster-acting embodiment uses a dual-ended siphon.

Abstract: ABSTRACT OF THE DISCLOSURE        A transducer having a field creating coil arrangement which produces a field having a field strength minimum, having a sensing coil positioned at that field strength minimum and responsive to changes in position of that minimum resulting from the proximity of an article to the field creating coil arrangement. By observing changes in the signal output of the sensing coil, infor-mation concerning the proximity of an article to the transducer is ascertained. Preferably the transducer includes a field disturbing means associated therewith for inducing a disturbance of the field created by the field creating coil so as to cause the sensing coil to operate by either simulating the disturbance of the field that would be caused by the proximity of an article or by disturbing the field while the article is present.         Thus the transducer may be remotely checked as to its operation.

Abstract: FINISH MEASURING METHOD AND APPARATUS            ABSTRACT OF THE DISCLOSURE         The amount of electrically conductive finish that has been applied to a filament is determined by measuring the con-ductance of a length of the filament.  The measurements are made independently of any differences in conductivity of finish mediums by means of a reference cell containing a sample of the particular finish medium used.  An electric measurement circuit provides an indication of the amount of finish medium on the filament by determining the ratio of the conductance of the length of filament to the conductance of the reference cell.  In one circuit embodiment, two operational amplifiers are placed in series.  The reference cell takes the place of the feedback resistor of one operational amplifier and the length of filament takes the place of the input resistance of the other amplifier.          The resulting output of the series circuit is a scaled ratio of the conductances of the finish along the length of filament and in the cell.  In another circuit embodiment, voltages applied through the length of filament and reference cell are selectively switched into a dual slope integrating circuit.  In its preferred form, the finish measuring apparatus is a hand-held device having contacts which may be connected to a filament using a trigger mechanism.
