Abstract: Inventor:  Everett E. Schulze, Jr. Title:     SWITCHING SYSTEM FOR SOLENOID RECIPROCATOR                 ABSTRACT OF THE DISCLOSURE        A switching system for a solenoid reciprocator motor of a type which has a piston arranged to reciprocate into and out of a solenoid.  The switch is an SCR rectifier and the trigger lead to close the switch is pulsed by a commutator operating is unison with the movement of the solenoid or a shaft rotated by the solenoid.  The energizing cycle when the SCR switch is closed is terminated by a disconnect lead which is pulsed re-sponsive to a subsequent contact of the circuit by the commu-tator.  A preferred mode of pulsing the disconnect circuit is to associate the disconnect circuit with another solenoid of the motor whereby the first solenoid is turned off when the other solenoid is turned on by the commutator.

Abstract: ABSTRACT      An actinide-containing organic waste is treated to achieve a substantial reduction in the volume of the organic waste and provide for recovery of the actinide constituent therefrom.  The organic actinide-containing waste is reacted with a source of gaseous oxygen in a molten salt bath main-tained at an elevated temperature to produce gaseous reaction products comprising carbon monoxide and water vapor.  The actinide and inorganic ash constituents of the waste are retained in the molten salt.  Intermittently or continuously at least a portion of the molten salt is withdrawn and mixed with an aqueous medium to dissolve the salt constituents.           The medium then is filtered to remove the insoluble inorganic ash constituents and the actinide. The filter cake then is leached with an inorganic acid to recover the actinide.  The filtrate is boiled, preferably in a zone of reduced pressure, to evaporate water and precipitate the alkali metal carbonate which is recovered therefrom for recycle to the combustion chamber.  The filtrate, after carbonate removal, is recycled to quench additional molten salt.  In a particular preferred embodiment, wherein the waste material also contains halides, the filtrate, after carbonate removal, is cooled to precip-itate an alkali metal halide which is recovered for disposal.           The filtrate then is recycled for use as the aqueous medium to quench additional molten salt.

Abstract: ABSTRACT OF THE DISCLOSURE     A meter prover is provided in which a substantially spherical plug travels through a U-shaped calibration conduit between two delivery/receiving stations at the ends of the conduit, and each said station contains means for selectively retaining the plug in the station.

Abstract: ABSTRACT OF THE DISCLOSURE                  A multi-purpose four-wheel drive vehicle is disclosed having four-wheel steering.  A hitch (68) is slung below the vehicle body between the front and rear wheels or forward of the front wheels.  By alinging the hitch in this manner the force applied to the rear wheels and also the front wheels, to move the vehicle forward, is given a component towards the ground so that the heavier the load towed and the greater traction required to pull the load the greater the vertical force applied to the wheels thereby increasing traction between these wheels and the ground.  The multi-purpose vehicle incorporates a relatively high ground clearance which is achieved by employing four vertical axles and wheels situated at the four corners of a main frame body of the vehicle.  The vertical axles are situated in respective spaced-apart leg post members (54a to 54d), each leg post member being rigidly interconnected by two spaced-apart longitudinally extending frame members (50,52) and two spaced-apart transversely extending frame members (56,58).  At least three (50,52,56) of the frame members are of torsionally resilient construction.  The vehicle incorporates a belt or chain and sprocket trans-mission for driving the vehicle which can also be used as an amphibious transporter.

Abstract: ABSTRACT OF THE DISCLOSURE          In certain wheel alignment measuring apparatus, a fixture is clamped to the rim of a wheel and an alignment sensor is pendulously mounted upon the fixture so that as the wheel is rotated the sensor will not rotate with the fixture.  However, since the plane of the fixture is not necessarily parallel to the plane of the wheel the sensor may oscillate relative to the ground surface as the wheel is rotated--a condition known as "runout" which results in sensor reading errors.  This is corrected by rotating the fixture to three separate rotative positions and recording the sensor readings at each such position.  Circuitry is provided for determining the true alignment of the wheel by calculating the amount of the runout error at the final rotative position of the wheel and correcting the sensor reading by this amount.

In both embodiments the locking cylinder comprises a housing, a working piston, a pilot piston, and a counter balance valve to substantially smoothen the operation of the working piston, particularly when an induced pressure is applied to the working piston.  In the first embodiment, the pilot piston slides as a unit, although it may be formed in two axially separate parts.  In the second embodiment, the pilot piston is formed in two axially separate parts, communicating bores are formed in the two parts, a ball valve is located in the bore in one of the parts, a free floating pin is disposed in the bores between the ball valve and an abutment surface in the other part, and the ball valve is biased shut.  The pin is sized to unseat the ball valve when the two parts are in contact, but the two parts are biased apart by the action of the biasing means, which is transmitted through the pin to the abutment surface.
