Title: Load plus differential pressure compensator pump control assembly
Inventor: LIESENER KENNETH P
IPC: F16H61/42
Filed: 1978-06-14
Granted: 1980-05-13
Abstract: LOAD PLUS DIFFERENTIAL PRESSURE COMPENSATOR PUMP CONTROL ASSEMBLY A first device for controlling the position of a displacement control member of a variable displacement pump has an actuator connected to the control member and a valve member which is movable between a first position at which a pump discharge pressure signal is in communication with the actuator and a second position at which said pump discharge pressure signal is blocked from communication with the actuator and the actuator is connected to a drain.  The valve member has an end substantially continuously exposed to the pump discharge pressure signal and is responsive thereto for biasing the valve member toward one of the first and second positions.  A spring apparatus biases the valve member toward the other of said positions in opposition to the biasing force of said pump discharge pressure signal and establishes a preselected minimum discharge pressure.  A second device increases the biasing force of the spring apparatus for increasing the pump discharge pressure in response to a load pressure signal exceeding a preselected pressure level.  The spring apparatus has a first spring positioned between the second device and the valve member and a second spring positioned between the housing and the valve member.  The second spring biases the valve member toward said other position independently of the first spring for maintaining the pump discharge pressure at a preselected value above the load pressure signal only in response to the pump discharge pressure exceeding  the preselected minimum discharge pressure level.

Abstract: A SILO UNLOADER SYSTEM          Abstract of the Disclosure A silo unloader system of the bottom unloader type has a radially disposed auger mounted at the bottom of the silo for movement comprising a radial sweeping movement across the floor by a sweep drive, combined with rotation of the auger about its own axis by a rotational drive.  Silage within the silo is engaged by advancing the auger into the silage and moving the silage toward a generally central silo discharge location by auger rotation.  The improvement resides in the rotational drive comprising a pivotally mounted electric motor and a drive train connecting the motor and the auger at a substantially radial inner portion of the auger at about the geometric center of the silo for rotationally driving the auger from its radial inner end.  In addition the sweep drive comprises a hydraulic cylinder drive mechanism operably associated with the electric motor.

Abstract: ABSTRACT OF THE DISCLOSURE           A combined fastener and tension indicator means employed for securing the ends of a band having undulations formed therein.  The band is employed for retaining insulation panels which have been applied over the exterior surface of a structure to be insulated thereby.  The structure to be insulated is caused to expand and/or contract depending upon the sur-rounding atmospheric conditions.  A tension is applied to the band to insure the band always being in close contact with the exterior surface of the structure to which the panels have been applied.  The undulations formed in the band together with the amount of tension applied to the band will permit for the structure to which the panels have been applied to expand and/or contract while still retaining the insulation panels in close contact with the exterior surface of the structure to which the panels have been applied.

Abstract: TITLE OF THE INVENTION:            NAVIGATION METHOD FOR PRECISELY STEERING A FLYING OBJECT            ABSTRACT OF THE DISCLOSURE            A flying object is precisely steered by determining the position of the flying object with the aid of a trigonometric calculation.  For this purpose pulse signals emitted in synchronism from two ground stations are received by the flying object and the time difference be-tween the two arrivals is measured.  The flying object is also equipped with a clock which is synchronized with the clocks of the two ground stations.  Thus, the emitting times are available in the flying object.  Based on the measured time difference between the receipt of the two pulses and on the given emission time the coordinates of the actual position of the flying object are calculated.          The calculated position coordinates are compared with position coordinates of a rated course stored in the air-borne equipment whereby a course deviation signal is cal-culated.  The course deviation signal is then applied to the steering mechanism of the flying object to bring the latter back onto the rated course.

Abstract: LOAD SENSING CONTROL VALVE                 ABSTRACT OF THE DISCLOSURE           A valve for  use in vehicle hydraulic brake systems for the purpose of limiting the rear wheel brake pressure relative to the front wheel brake pressure. in order to reduce the potential for premature rear wheel lock,. The valve includes a proportioning piston which operates to limit the fluid pressure delivered to the rear wheel brakes and an inertia member which senses changes in vehicle loading. When a vehicle is fully loaded, the inertia member remains in a position where it will disable the proportioning piston in its open position and, consequently, The rear wheel brake pressure will be equal to the front wheel brake pressure.  When the same vehicle is unloaded, the inertia member moves in response to deceleration to a position where it will not: disable the proportioning piston in its open posi-tion so that the rear wheel brake pressure will be reduced relative to the front wheel brake pressure. The valve may also include a valve assembly which by-passes the proportioning piston to increase the rear wheel brake pressure subsequent to a period when the rear wheel brake pressure is limited.
