Abstract: A flexible and bowed tow hitch having a A-configuration is adapted for tring a sled behind a snow vehicle. The hitch comprises three plastic straps; two straps form the legs for the A-configuration and the third strap forms the cross-bar for the A-configuration. The ends of the cross-bar strap are physically pressed against the respective ends of the leg straps to form the base terminal of the hitch for attachment to the sled. The other ends of the legs are physically pressed against each other to form the apex for the A-configuration. An elongated bar is embedded between these other ends. The bar is welded to a ring member to form a lunette-type connection for attachment to the snow vehicle.

Abstract: A controlled rectifier firing circuit for the warhead of a missile located n a rocket powered test sled traveling along a track in a target vulnerability test range. The firing circuit includes a silicon controlled rectifier which when rendered conductive discharges a capacitor to fire a warhead detonator. A relatively high voltage DC source is coupled to the capacitor prior to sled travel toward the target. A second capacitor is also charged from the high voltage source and discharges through a resistance when an impact type actuator switch is closed at the time of detonation. The voltage developed across the resistor is coupled to the gate electrode of the silicon controlled rectifier which renders it conductive, causing the first capacitor to discharge through the detonator to fire the warhead.

Abstract: An electronic memory device is disclosed which utilizes silicon-on-sapphire SOS) transistors that exhibit binary states dependent upon the dose of ionizing radiation to which they are subjected. A memory utilizing such SOS transistors may have information written into it, permenently or for a short period of time, by electron-beam bombardment so that the memory operates as a PROM. The memory may also operate as a RAM when a scanning electron beam, in conjunction with appropriately applied biases, is used to read and write information at a high rate.

Abstract: A microwave rf envelope generator or pulse shaper has a main waveguide with two opposing branches connected in shunt to the main waveguide and are terminated with variable positionable shorts. The characteristic impedance of the shunted combination of the two branches equal one half the characteristic impedance of the main waveguide. An incident rf pulse applied to an input of the main waveguide is transmitted to a four way junction formed at the intersection of the two branches. The incident pulse is divided at the junction. Divided pulses are then transmitted down each of the branches and to an output of the main waveguide. The pulses traveling down each branch will have their phases shifted when they are reflected by the variable positionable shorts. The lengths of the branches are adjusted by the variable shorts so that the phase of the reflected and inverted pulses will cancel the trailing portion of the pulse transmitted out towards the output of the main waveguide.

Abstract: A null balanced fluidic sensing system that is less susceptible to pressure upply disturbances includes sensing and amplifying elements in a closed loop arrangement. The differential output of the sensor, developed as a result of an input stimulus, is fed into the inputs of a single sided amplifier. The output of the amplifier is used as a source of supply for the sensor. This closed loop arrangement uses the null offset characteristics of the elements to create a null balanced fluidic sensing system.
