Abstract: ABSTRACT          A receiver for angle-modulated signals of the type a sin ((.omega.) t + ? (t)), comprising a frequency transposition stage incorporating a local oscillator.  A frequency shift .DELTA..omega. of the local oscillator rela-tive to the carrier frequency .omega. may cause the angle modulation signal ?(t) to become faded.  An argument detector produces ehe signal [? (t) + (.DELTA..omega.) t] which is differentiated by a differentiator to provide the signal [d ?(t)/dt + .DELTA..omega.]. A DC-shift detector determines the DC-component .DELTA..omega. of this signal.  This component is  integrated  by an integrator to provide the signal (.DELTA..omega.) t, which is thereafter subtracted by difference producer from the output signal of the argument detector to provide a clear angle modulation signal.  This receiver is suitable for use in systems for the radio transmission of data signals.

Abstract: FAUCET ASSEMBLY WITH P INCH VALVES                    ABSTRACT OF THE DISCLOSURE           A faucet assembly including pinch valves for con-trolling the flow of hot and cold water.  A base is secured to the deck of a sink from above the deck and a body secured to the base completes the faucet housing.  A spout extends over the basin and includes an outlet at its end.  Two flex-ible tubes are connected to a mixing chamber near the outlet and extend through the spout and through the base for connec-tion to hot and cold water conduits remote from the sink deck.          The tubes are normally pinched closed adjacent the mixing chamber by springs, and operating levers at opposite sides of the spout rotate about a shaft and operate a linkage and valve mechanism for overcoming the spring forces to permit flow.          Lost motion connections render the spring closing forces independent of lever position.  A cross bar limits lever movement and provides a support surface against which the tubes are pinched.  The tubes are located in the valve region by a block which serves as a barrier to leakage.

Abstract: ABSTRACT A rotary actuator assembly for positioning read/write heads in disk drive mass storage systems.  The actuator assembly includes an actuator motor and one or more actuator arms secured thereto.  The motor provides rotary motion of the arms, to move the heads.  The stator magnet of the motor is an electro-magnet wound on an arcuate core; a pair of elongate permanent magnets are attached to the rotor member, for coaction with the stator magnet.  The rotor member has a U-shaped cross sectional area in a plane perpendicular to its axis of rotation; the permanent magnets are fixed to the outside, bottom corners of the U and the actuator arms are mounted across the open end of the U.  The rotor is of a very small radius, to minimize inertia.  The permanent magnets have a flat face facing the stator, with a channel running longitudinally down the middle, to minimize flux density variations in the permanent magnet-coil gap. The rotor balances the arm relative to the rotor's axis.  The arms are of a substantially symmetrical tapered truss design, presenting low inertia; each is cantilevered to the rotor by one bolt which is passed through and pulls the arm against the rotors.  Additionally, a spirol-type cylindrical spiral spring, received in a slot in the arm, prevents lateral slippage of the arm relative to the rotor.  A pair of cantilevered leaf spring crash stops fixed to the stator decelerate the rotor at the ends of its range of travel.
