    摘要: A mechanically operable solid state switch particularly suited for use in achieving a variable circuit-switching function in an environment wherein ''''bounce'''' and ''''arcing'''' between switch contacts are to be avoided, characterized by an annular array of photo-responsive switching devices, disposed in communication with an included source of radiation, and a plurality of interchangeable, mechanically operable interrupter disks, each having a predetermined pattern of transparent and opaque portions and adapted to be interposed in a masking relationship between the source of radiation and the array of photo-responsive devices, whereby an operative displacement of each disk serves to MAKE and BREAK selected electrical circuits through the photoresponsive devices of said array in sequences dictated by said pattern of the opaque and transparent portions of the interrupter.

    摘要: A radar transmitting system is disclosed for transmitting an optical pulse to a target comprising an optical cavity containing a laser incorporating a mode-locking means to build up an optical pulse. An optical switch is also provided within the cavity to convert the polarization of the optical pulse generated within the cavity. The optical switch comprises an electro-optical crystal driven by a time delayed driver circuit which is triggered by a coincident signal made from an optical pulse signal and a gating pulse signal. Upon being energized, the electro-optical crystal functions to convert the polarization of the optical pulse as it passes through the crystal. This converted optical pulse then strikes a polarization sensitive prism and is deflected out of the cavity toward the pending target in the form of a pulse containing most of the optical energy generated by the laser in the pulse build-up period. After striking the target, the reflected energy is picked up by a transceiver with the total travel time of the pulse being recorded. This travel time is a measure of the distance from the transceiver to the target.

    摘要: The loop signal-to-noise ratio is improved in a phase-locked loop used for tracking a carrier in an angle (phase or frequency) modulated communications system by a quadrature channel added to the phase-locked loop. A d-c signal derived from the quadrature channel is added to the signal fed back to the voltage controlled oscillator in the otherwise conventional phase-locked loop.

    摘要: A firearm in the nature of a rifle with a plurality of exchangeable barrels, any one barrel being adapted to be threadedly connected to the receiver of the action. Thus, barrel replacement is accomplished by retraction of a set screw and unthreading of one barrel from the receiver and, thereafter, threading of a second barrel in its place and tightening of the set screw, once proper receiver-barrel alignment is achieved. Barrel exchange is accommodated by a depressible stock insert which yields to dimensional variations of each barrel during barrel removal and replacement. A wrench-receiving counterbore at the distal end of each barrel permits suitable tightening of each barrel prior to firing. Barrel alignment is achieved by use of alignment markings on the distal end of the receiver and the proximal end of each barrel.

    摘要: A temperature control system is disclosed which includes a modified wheatstone bridge with a resistive-capacitive (RC) circuit in one leg of the bridge. The RC circuit includes a resistor which provides an effective resistance as a function of its absolute resistance and the on-time to off-time ratio of pulses supplied to a switch connected thereacross. A sawtooth voltage is produced across the RC circuit, the voltage being compared with the voltage across a temperature sensor, with heat being applied during each pulse period portion when the sawtooth voltage exceeds the voltage across the temperature sensor.

    摘要: An active aerodynamic control system to control flutter over a large range of oscillatory frequencies unaffected by mass, stiffness, elastic axis, or center-of-gravity location of the system, mode of vibration or subsonic Mach number consisting of one or more pairs of leading edge and trailing edge hinged or deformable control surfaces, each pair operated in concert by a stability augmentation system. Torsion and bending motions or deflections of the fluttering member are sensed and converted by the stability augmentation system into leading and trailing edge control surface deflections which produce lift forces and pitching moments to suppress flutter.

    摘要: A two-channel telemetry system is disclosed in which one channel is used for high-rate data and the other channel for low-rate data communication. In the transmitter a signal, which subsequently phase modulates a carrier, is produced which is a function of at least the high-rate data, the low-rate data and the frequency of the subcarrier of the low-rate channel. In the receiver which includes a phase-locked loop, the high-rate data is detected off the receiver inphase channel output and the lowrate off the quadrature channel output.
