  • Patent number: 4543655
    Abstract: The improved free electron laser device for scanning a spatial field is generally comprised of a drift tube and a rotatable mandrel. The mandrel is concentrically disposed in the tube so as to define an annular space therebetween. A series of canted mirrors of grooved-like configuration are formed about the mandrel in predetermined spaced relationship to each other and at a predetermined angle to a plane transverse of the mandrel. These mirrors function to reflect and phase redistribute various waves of the wave front so as to form a plurality of asymmetric diffraction patterns in the annular space. By reason of the nutating effect of the canted and rotating mirrors, the projected beam conically and continuously scans a region of the spatial field. In order to minimize the effect of skew waves, a series of circumferentially spaced and longitudinally extending rib-like baffles can be affixed to the tube interior between adjoining mirrors.

  • Patent number: 4517515
    Abstract: A magnetic-field detection device useful as a sensitive magnetometer. The device employs a solid-state field-sensing element which experiences a change in permeability when it is exposed to a magnetic field. The change in permeability results in a change in skin depth and therefore in resistance offered by the element to passage of a high-frequency alternating current. The element is used as one arm of a balanced bridge circuit to which an A.C. voltage is applied. Upon exposure to a magnetic field, the bridge is rebalanced to a null, the amount of current flow or rebalancing being measures of the magnetic field strength.

  • Patent number: 4493195
    Abstract: An air conditioning system with incorporated evaporative cooling apparatus dapted to sequentially pass compressed air from a compressor through a heat exchanger and expansion cooling turbine and into an enclosure. A condensate extractor is interposed downstream of the expansion cooling turbine and located above the heat exchanger. A nozzle is mounted to the heat exchanger and connected via a water conduit to the condensate extractor so that gravity delivers extracted condensate to the nozzle. The nozzle communicates via an air conduit with the compressor so that compressed air disperses the extracted condensate through the nozzle to impinge upon the heat exchanger thereby effectuating evaporative cooling.

  • Patent number: 4470562
    Abstract: An inertial guidance system for a rocket powered ballistic missile which vides navigation and control while the missile is proceeding in its flight trajectory. Signals are generated within the confines of the missile and without outside information representative of angular and linear motion of the missile with respect to an inertial frame of reference, a digital computer compares these signals against a preset parameter stored in the computer to provide control signals along the pitch and yaw axes. An autopilot uses these control signals to provide mechanical control movements, and an exhaust nozzle deflection arrangement connected to the autopilot deflects the exhaust of the rocket for guidance along a predetermined flight trajectory.

  • Patent number: 3957340
    Abstract: An optical waveguide system for transforming the output of a phase modulator into an amplitude modulation. Laser light propagating in the waveguide is forwarded into branches in the waveguide. An electrooptic material placed in one or more branches is electrically controlled to vary the phase in each branch causing different propagation modes. The branched optical radiation or coherent light is then recombined in a single branch and subsequently branched again with each subsequent branch propagating a different mode. By tapering one of the latter branches to zero thickness, selective modes can be blocked resulting in amplitude modulation.

  • Patent number: 3958189
    Abstract: An improved apparatus and technique for providing tunable high power millimeter and submillimeter radiation. A tunable source of microwave energy is coupled to an evacuated drift tube in which an intense relativistic electron beam is propagated while constrained in a magnetic field having a direction parallel to the direction of the electron beam. The microwave energy is directed in a direction opposite to the direction of the electron beam to generate millimeter or submillimeter radiation by backscattering from the intense relativistic electron beam. By tuning the frequency of the microwave energy to be mismatched by a specific amount from the electron cyclotron frequency in the rest frame of the electrons at high beam currents, a coherent scattering of microwave energy from electron bunches will produce enhanced power output of millimeter and submillimeter radiation.

  • Patent number: 3954015
    Abstract: A method of ascertaining the piezoelectric constants (d.sub.31, d.sub.33, sub.31, and g.sub.33) of ceramic cylindrical shells (rings) used as the active elements in hydrophones and sound sources to insure quality control. These constants may be obtained by measuring the electrical capacitance of the ring and by measuring the omnidirectional free-field voltage sensitivity, the ratio of the axial and radial sensitivity at a higher frequency and the physical dimensions of the ring. Since the required frequencies are low and the ring is symmetric, the acoustical measurements can be made in a closed mechanically driven air chamber.

  • Patent number: 3949396
    Abstract: A new system and technique for providing multi-mode radar operation from a ingle scanning radar antenna at conventional scan rates. A single radar antenna has a plurality of feeds forming individual main-lobe beams equal in number to the number of radar modes to be utilized. Each of the beams is separated in azimuth by a fixed angle .theta., and rotate together at the scan rate of the antenna. For each angle .theta. that the antenna rotates the radar mode is changed so that the antenna feeds are cyclically multiplexed to each of the radar modes desired.

  • Patent number: 3947706
    Abstract: An improved circuit for compensating for temperature and current variations n rectifier circuits used for converting alternating current to a proportional direct current, particularly at low voltages. A separate rectifier to be used as a circuit standard is maintained in close thermal proximity to other rectifiers as part of the conversion circuit. A voltage proportional to that across the standard is applied as a bias to a terminal of the circuit rectifiers to automatically compensate for temperature and current changes in the circuit and thereby provide a more accurate rectification of an input voltage.
