Abstract: ABSTRACT           A method, a preformed part and an apparatus  for forging crank throws comprising upsetting a portion of a bar and directing the flowing material to form a preformed part having at the ends of the upset portion two upsets (27a) situated eccentrically to the axle of the bar. To form the ready forging a bending force is applied against the central portion of the preformed part, between the two eccentrical upsets (27a).  The bending force is perpendicular to upsetting force and is opposite to the crests of the eccentrical upsets. During forging operation the bar is fastened between segment dies (20, 21) mounted in upper and lower die holders (7, 18). The lower die holders (7) are supported by artitiulated links (5,11) pivotably mounted to a fixed base.  On this base a bending tool (23) is mounted.  The upper die holders are sli-dably mounted to a head, which is fixed to the press ram. To the head an anvil (25) is fastened.  This anvil has two working faces, which are interchangeable during the crank throw forging process.             Drawings: Fig. 7 and 1 of the Application

Abstract: ABSTRACT OF THE DISCLOSURE        A set of two two-degrees-of-freedom rate gyroscopes and three linear accelerometers are assembled in a single module adapted to be mounted within a single aircraft electronics control unit, the unit comprising a strapped-down attitude and heading reference system.  The module base provides a common keyed support for the two pre-calibrated gyros and three accelerometers in intimate mechanical and thermal association.   The two gyros are oriented in the base and the base oriented in the aircraft so that the spin axis of one gyro is oriented parallel to the aircraft Z axis and that of the other gyro parallel to the aircraft Y axis while the gyro pickoffs and torquers (input and output axes, respectively) are rotated or skewed forty-five degrees about the spin axes to positions such that the input and output axes lie along the slant heights of a forty-five degree half angle right circular cone, the axis of which lies along the aircraft X axis.  Thus a single module provides greatly simplified rate sensing about the aircraft primary axes with correspondingly simplified fault detection of the rate sensors.

Abstract: ABSTRACT OF THE DISCLOSURE    A filtration device for effecting separation of a blood cell-free liquid filtrate from a blood cell-containing liquid suspension in continuous laminar flow therethrough, employing a microporous filtration membrane.  The filtration flow channels along the surface of the upstream side of the membrane wall are provided with a width across the membrane wall surface which gradually and uniformly increases from the inlet end to the outlet end of the flow channel, whereby the membrane wall shear rate of the suspension in laminar flow through the flow channel will gradually and uniformly vary along the length of the flow channel from a maximum value at its inlet end to a minimum value at its outlet end.  Such variation in shear rate corresponds with the variation in the transmembrane pressure conditions along the length of the flow channel so as to enable better control of the filtration operating conditions to ensure optimal filtration rates per area of membrane without damage to the blood cells.  Useful applications of the device include the separation of plasma from whole blood in a continuous flow plasmapheresis procedure, and the removal of cryoprotective agents from previously frozen, thawed preparations of blood cells.

Abstract: DPP/1kb/dl 22828 12/11/79 LOAD HANDLING VEHICLE WITH ROTATING          GRAPPLE MECHANISM                           Abstract A load-lifting mechanism at the front of a lift truck carries an upright boom with a pair of parallel spaced-apart forwardly cantilevered boom portions rotatably supporting a horizontal pivot tube between their forward ends.  A vertical pivot shaft rotatably carried by the pivot tube suspends a grapple beneath the cantilevered boom portions.  The grapple includes a yoke mounting and a pair of grapple arms opened and closed by single or dual hydraulic cylinders.  A mechanical link interconnects the grapple arms so that they open and close together and to the same extent.  A pair of fluid cylinders on the canti-lever boom portions pivot the pivot tube to swing the shaft and grapple fore and aft.  A rotation mechanism between the cantilever boom portions and their cylinders rotates the pivot shaft and connected grapple about the axis of the shaft.  The mechanism is carried by a V-shaped framework supported by the pivot tube and includes a first fluid cylinder connected at one end to the framework and at the other end to a first floating lever rotatably mounted on the pivot shaft.  A second floating lever connected to the first lever is also rotatable on the pivot shaft.  A second fluid cylinder is connected at one end to the second lever and at the other end to a crank lever fixed to the shaft.  By stroking these cylinders to operate the levers, the grapple can be pivoted in either direction through an arc of at least 180° about the axis of the shaft.

Abstract: ABSTRACT OF THE DISCLOSURE    A method of and an apparatus for selectively isolating digital data bus drivers from digital data busses for fault recovery and diagnostic purposes.  The digital data bus drivers may be either transistor-transistor logic (TTL) or emitter coupled logic (ECL).  For TTL digital data bus drivers, the input voltage (VCC) is supplied via a switching power transistor.          For ECL digital data bus drivers, the ground connection (VCC1) is made via a switching power transistor.  In either case, the switching power transistor is turned on and off in response to one binary bit in an isolation register coupled to the power transistor via an open collector gate or electromechanical switch.  By supplying the VCC (for TTL) or VCC1 (for ECL) connection to each digital data bus driver through a switching power transistor and controlling each switching power transistor through a different binary bit in the isolation register, the isolation (or non-isolation) status of each digital data bus driver may be controlled via the isolation register to permit the digital data bus to operate notwithstanding failures effecting the state of one or more of the digital data bus drivers connected to it.

Abstract: Inventor:          Frank L. Stromotich Title:      Compound Epicyclic Cog Belt Speed Reducer ABSTRACT             In a speed reducer, a reaction sun is held stationary relative to a frame and an output sun is coaxial with the reaction sun.  An idler carrier assembly, rotatable relative to the frame about the common axis of the two suns, carries a planet shaft supporting a reaction planet and an output planet for conjoint rotation and in radial alignment, respectively, with the reaction sun and the output sun.  Rotation of the idler carrier assembly effects orbiting of the planet shaft and its planets about the common axis of the suns.  Endless loop force-transmitting elements connect corresponding suns and planets.  Rotary input power is applied to the planet shaft effecting conjoint rotation of the planets and orbiting of the planets about the suns' axis.  The epicyclic motion of the output planet effects rotation of the output sun.  In a preferred embodiment, an input shaft carries a separate input sun coaxial with the other suns; the planet shaft supports an input planet in addition to supporting the output and reaction planets; and the input sun and the input planet are connected by an additional endless loop force-transmitting element.  The input shaft is driven by a high-speed electric motor at a speed of at least 3,000 rpm and the velocity ratio of the speed reducer is at least 1,000:1.

Abstract: DEAD-FRONT ELECTRICAL WIRING DEVICE    ATTACHABLE TO A POWER CORD      ABSTRACT OF THE DISCLOSURE   Disclosed is an electrical wiring device attachable to a power cord, formed of two pieces, and having a dead-front supporting contact elements of the male or female type.  One of the pieces comprises the dead-front and the contact elements that it supports, inte-grally hinged to a first sidewall member.  The dead-front in an outwardly swung position exposes the con-tact element terminals in a manner to facilitate con-nection of the power cord conductors to the terminals.          When the connection is made, the dead-front is swung inwardly to a position in which the conductor lies upon the first sidewa-l member.  A second sidewall member or cover, forming the other piece, is then slidably inter-engaged with the inwardly swung dead-front responsive to movement of the cover into a position overlying the first sidewall member.  When fully interengaged with the dead-front, the cover cooperates with the dead-front and with the first sidewall member in defining an insulated, fully enclosed housing within which the terminals are confined.          The cover and the first sidewall member have cooperating strain-relief means between which the power cord is clamped.  In the assembled relation of the two pieces, screws captive in the first sidewall member are thread-able into the cover to complete the assembly.  The parts are in this way securely interlocked with the terminals completely enclosed in back of the dead-front of the device.

Abstract: PICK-UP FOR AN ELECTRICAL MUSICAL INSTRUMENT             OF THE STRINGED TYPE                 ABSTRACT           The present invention relates to a pick-up for an electrical musical instrument of the stringed type.  Prior art pick-ups have included pick-ups having two pick-up assemblies having opposite polarity and opposite winding and con-nected in series for humbucking, but the prior art pick-ups have required the use of external circuits or special sound production devices in order to provide desired enhancement of the bass frequencies. The present invention provides a pick-up having increased bass response, suitable for use with ordinary sound systems.  The improvement is achieved by optimally positioning two individual pick-up assemblies to respond to bass and to treble frequencies respectively, the two pick-ups being electrically connected in series, and the treble response of the pick-up which is optimally positioned for bass response being electrically suppressed.
