Title: Supplementary hydrostatic drive electronic  control
Inventor: PFUNDSTEIN DONALD K
IPC: B60K17/10
Filed: 1979-03-08
Granted: 1981-12-01
Abstract: SUPPLEMENTARY HYDROSTATIC DRIVE       ELECTRONIC CONTROL          Abstract of the Disclosure An electronic control for a vehicle supplementary hydro-static front wheel drive includes a rear sensor for providing a command signal representative of the speed of differential con-nected, engine-driven, main drive wheels.  A front sensor provides a feedback signal representative of the speed of the hydrostatic drive motors.  The command signal is modified to provide a modi-fied command signal to be summed with the feedback signal to provide servo circuitry with a servo signal which is representa-tive of the front wheels being driven 3% slower than the rear wheels.  Electrically actuated, pressure responsive clutches allow the front wheels to overrun the hydrostatic drive motors until the slip at the rear wheels exceeds 3%, then the front wheels drive to supplement the main drive wheels.  A selectable overspeed circuit is provided which can modify the modified command signal to provide a servo control signal which represents the front wheels being driven 1% faster than the rear wheels so as to provide a continuous, positive supplementary drive regard-less of rear wheel slip.  The servo control signal is processed through direction controllers which input the direction of the main drive wheels and which supply control signals to a servo actuator on a reversible hydraulic pump which powers the hydro-static drive motors for drive in accordance with main drive speed and direction.  Both the servo and overspeed circuits are connec-ted to a hold circuit which activates and holds the overspeed circuit on to provide quick response when the direction of the main drive is changed.

Granted: 1981-08-18
Abstract: ABSTRACT OF THE DISCLOSURE     A continuous process is disclosed for producing a heather yarn from a continuous filament polyester feed yarn having a residual draw ratio in the range of from 1.6 to 2.0 and a continuous filament polyamide feed yarn having a residual draw ratio in the range of from 106 to 120 per-cent of the residual draw ratio of the polyester feed yarn. The process involves the steps of: (1) combining the yarns; (2) false twist texturing and drawing the combined yarns in a draw-texturing zone comprising feed rolls, a heating means, a friction twisting element and draw rolls; (3) randomly entangling the combined and textured yarns together in a jet-intermingling zone formed by an air jet device; and (4) withdrawing the heather yarn so produced.

Abstract: ELECTROMAGNETIC FUEL INJECTOR                     ABSTRACT OF THE DISCLOSURE    A high flow rate electromagnetic injector valve with a rapid response time and a method for calibrating such injector is disclosed  for utilization in a single point fuel injection system.  Centrally bored end caps are fixed at the front and rear ends of a tubular injector body and a coil wound on a bobbin is disposed inside the body chamber between the end caps.  The front end cap receives within its bore a valve assembly including a valve housing and a needle valve with attached armature reciprocally movable against a valve seat to obturate a metering orifice in the valve housing.  The valve housing contains fuel inlets for the pressurized entry of fuel into the injector and the needle valve is ported to provide fluid communi-cation to the armature to relieve pressure build-up.  The rear end cap mounts within its bore a core member acting as a stator which extends through a central bobbin bore to form a controllable air gap adjacent the armature, the core member further contains internally an adjustment screw and ball member.          The ball member and adjustment screw cooperate with a recessed closure spring positioned substantially within the armature to controllably bias the needle valve against the valve seat.  By the adjustment of the core member and the adjustment screw both the static fuel flow and the dynamic fuel flow of the injector are respectively calibrated.  Because of its recessed position, the force of the closure spring is applied substan-tially along the central axis of the injector valve and the ball member prevents torsional windup forces from being generated by the spring.  O-ring seals for the bobbin bore are provided in compression between recesses in the bobbin and the slower contracting material of the front end cap and core member to produce extended cold temperature operation.

Abstract: EASY-LOAD RECORD MATERIAL FEED APPARATUS        ABSTRACT OF THE DISCLOSURE   Apparatus for feeding marginally punched record material comprises a main support member, and a plurality of drive pins mounted to the main support member for movement along a predefined path past a first location at which record material is inserted into the apparatus. Means included on the main support member adjacent the first location facilitates the buckling of record material inserted into the apparatus in a direction away from the pins during movement of the pins along the predefined path when there is no initial engagement of a pin with a marginal opening of the record material. When a pin thereafter moves into substantial registration with a marginal opening of the record material, the natural bias of the buckled portion of the record material in the direction of the pins will return it to a substantially unbuckled state to thereby engage the pin with the opening.

Abstract: ABSTRACT OF THE INVENTION     An improved integrated and cyclic process and apparatus are disclosed wherein portions of various process and waste fluids are recycled to control impurities in the influents to membrane chlor-alkali cells and simultaneously to minimize liquid pollutants from the process.  Part of the liquid effluent from the cathode compartments is used to control the pH of the brine feed during precipitation of non-monovalent cations as insoluble salts; to absorb chlorine recovered from recycled liquid effluent from the anode compartments and optionally to regenerate anion exchangers used to demineralize water influent to the cathode compartments, the spent regenerant being recycled to conserve alkali and monovalent cations.  In a process of electrolyzing alkali metal chloride solutions wherein anode and cathode compartments are separated by fluid impermeable, cation permselective perfluorocarbon membranes, a saturated chloride solution is mixed with a compound from the group of phosphoric acid, alkali metal carbonates, bicarbonates, phosphates and acid phosphates, and the pH is adjusted to 10 with alkal1 metal hydroxide effluents.    The pretreated solution is then contacted with a chelating cation exchanger in the monovalent cation form.  The effluent from the anode compartments is maintained in the range 2 - 4.  Hydrogen from the cathode compartments is combined with chlorine from the anode compartments, and the chelating cation exchanger is regenerated with a portion of the hydrochloric acid solution thus produced.
