Abstract: RCA 71,891 AUTOMATIC PEAK BEAM CURRENT LIMITER                   Abstract of the Disclosure In a video signal processing system, apparatus for limiting excessive peak and average beam currents demanded by a kinescope in response to image representative video signals.  A control signal derived by a sensing circuit in response to excessive beam current is applied to the kinescope in a manner to limit excessive beam currents above a threshold level.  The sensing circuit includes a capacitor arranged with a conductive diode to form an average responding filter such that the sensing circuit derives a control voltage representative of excessive average beam current in a first beam current limiting mode.  In a second beam limiting mode, when beam current exceeds a predetermined level, the diode is rendered nonconductive and the capacitor is decoupled for average detection purposes.  In this mode, the control signal is free to vary in accordance with rapid variations in peak beam current.

Abstract: Applicant:     Frank L. Stromotich Title:         An Improved Epicyclic Cog Belt Speed Reducer ABSTRACT OF THE DISCLOSURE           In a speed reducer, a reaction sun is fixed to a frame and an output sun is coaxial with the reaction sun. An idler carrier assembly, rotatable 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 planet 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 electric motor drives the planets shaft directly and is mounted on the idler carrier assembly for orbiting with the planet shaft.

Abstract: ABSTRACT OF THE DISCLOSURE      Vinyltrialkylsilane - hexaorganocyclotrisiloxane block-copolymers of the formula:       wherein R and R' are the same or different and each repre-sents methyl or phonyl; each of R1, R2, R3 is an aliphatic radical containing 1 to 4 carbon atoms; Z is a residue of a dilithium initiator of polymerization of a vinyltrialkyl-silane, K is a residue of a monolithium initiator, which is a hydrocarbon radical selected from normal and an iso-alkyl radical; K' is hydrogen; a hydrocarbon radical or (R?) Si silcarbonic group wherein R" is a C1-C4 alkyl radical; a = 0 to 104; b - 0 to 104; c = 10 to 104; d = 10 to 104; f = 0 to 1; g = 0 to 1, x ? 1, with a molecular mass of from 103 to 106.  A method for preparing said block-copolymers com-prises polymerization of vinyltrialkylsilanes in the pre-sence of mono- or dilithlumorganic initiators, whereafter a solution of a hexaorganocyclotrisiloxane is added to the reaction mixture and polymerization is effected to give in-termediate block-copolymers whereafter the polymerization is stopped or said intermediate block-copolymers are com-bined by means of a cross-linking agent, followed by recov-ery of the desired product.  The block-copolymers according to the present invention feature a high selectivity of per-meation for certain gases.  Thus, the ratio of permeability constants for oxygen and nitrogen (Po2/PN2) is as high as 3.5.  At the same time, the absolute value of gas-permeabil-ity constants is also high, i.e. PO2 is as high as 1.4 x 10-8 cm3. cm/cm2.cm Hg.sec.

Abstract: TITLE          WINDING SYSTEM FOR FLEXIBLE CONDUITS AND CABLES           ABSTRACT OF THE DISCLOSURE         A cable winding system carried by a vehicle for ex-tending and retracting cable responsive to vehicle movement.      The cable frictionally engages a controllably powered sheave and is guided into a horizontally disposed coil by a cylin-drical guide arm having a vertically directed opening adjacent the sheave and a downwardly, radially and circumferentially directed opening adjacent the coil.  The guide arm is freely rotatable about a vertical axis so that as cable is extended and retracted the guide arm rotates to guide the cable between the coil and sheave.  The powered sheave directs cable from the vehicle through an instrumented fairlead which, through a control system, controls the operation of the sheave.  The fairlead is pivotally mounted about a horizontal pivot axis so that the head pivots in one direction as the cable is ten-sioned and in the opposite direction as the cable tension is relieved.  The control system measures the angle of the fair-lead and may also measure the vehicle speed to cause the sheave to extend cable as the fairlead moves rearwardly and/or or the velocity of the forward vehicle is increased and to retract cable as the fairlead moves forwardly and/or the for-ward velocity of the vehicle is reduced.  Also included is a failsafe system for applying the brakes of the vehicle when the supply of cable in the coil falls to a predetermined value or when the fairlead pivots to a point indicative of excessive cable tension and the rotational velocity of the powered sheave is below a predetermined value.

Abstract: Abstract of the Disclosure In a shaft seal of resiliently deformable elastomeric material and which comprises a seal body of annular form having a longitudinal axis and having an annular front face, an annular rear face, an annular inner face, and an annular outer face, and a frusto-conical sealing flange extending outwardly and forwardly from the front face of the seal body adjacent the inner face thereof, there can be a tendency when the seal is in use with the seal body resiliently deformably mounted on a rotatable shaft and with the sealing flange in bearing contact with a fixed wall having an opening through which the shaft is disposed for the seal operatively to move axially and radially relative to the shaft particularly when the shaft is rotated at high speed. To reduce this tendency the inner face of the seal body has an annular concavity which operatively provides a suction cup effect more firmly to secure the seal body to the shaft, and the rear face of the seal body has an annular concavity which, with the seal body operatively resiliently deformed in tight contact with an annular shoulder presented by the shaft, likewise provides a suction cup effect between the seal body and the shoulder.

Abstract: MATERIAL LIFT PLATFORM     ABSTRACT OF THE DISCLOSURE         A hoist for loading and unloading cargo through a side or rear doorway of a van or truck slides from a stored position completely inside the vehicle to an operat-ing position with a lift platform outside the vehicle that can be lowered and raised by an electric winch connected to the platform by cables.  The hoist has a pair of generally horizontal telescoping parallel beams guiding a sliding yoke movable by means of the winch to raise and lower the platform through cable runs secured to means at both sides . of the platform.  Pivoting side support beams cooperating with stop members upon extension to operating position, and other safety features prevent improper operation.  If very heavy loads are to be lifted on to a small vehicle, it may be desirable to brace the vehicle, as by means of a jack at or near the location of the lift platform to avoid tilting the vehicle.  The material lift platform of the invention makes it possible to use a small truck or van to carry cargo that would otherwise require the use of a large truck, thus resulting in great fuel economy.

Abstract: ABSTRACT          Incoming diphase signals E which have base bit intervals delineated by spaced clocking signals with data information occurring between the clocking signals are fed to a four bit shift register 10 which in cooperation with an exclusive OR-gate 14 generates a pulse D for each diphase signal E transition.  Upon receipt of a preamble comprising four diphase signal transitions, a shift register 16 pro-vides a signal MSR which initiates the decoding of the following data information.  A counter 24 stores counts related to the time intervals between each two successive clocking signals and counters 26 and 28 store a count related to an immediately subsequent time period which is three-fourths of the time interval.  The occurrence of data information is sensed by a logic array 20 during successive time periods and a non-return to zero mark-space output signal K is stored in a flip-flop 22. The logic array 20 continually updates the mounts stored by the counters 24, 26-28.  Thomas 2
