  • Patent number: 5598414
    Abstract: A transmit-receive station connected to a high speed ring bus carrying data signals that may be received from and sent to each station on the ring bus has two sources of transmit clocking signals. One source is based on the frequency and phase of data signals received on the ring bus from another station and the other source is a local crystal oscillator having essentially the same frequency as the first source but in an indeterminate phase. When changing the source of clocking signals for transmission of data originating at the station, bit slippage may be minimized by providing the local oscillator output signal in four phases and using the phase most nearly aligned with the other clocking signal when the change is made. Control of access to transmit by a station employs a token having a message field of seven bits and a access control bit.

  • Patent number: 5444208
    Abstract: The serial arc plasma injectors device disclosed herein enables the formation of a segmented, isolated chain of plasma arcs which are incubated to form a specified energy level of plasma discharge tailored to initiate ignition and establish efficient combustion in a particular segment of a propellant mass. The device includes a capillary in which a conductive path comprising electrodes is maintained. Particularly, specialized electrodes provide geometric and dimensional flexibility to establish plasma arc and plasma discharge characteristics that are compatible with different zones of the propellant mass. The specialized electrodes in combination with discharge vents enable the development of a series of regions in the capillary through which plasma discharge is introduced into the propellant mass to selectively initiate ignition and promote efficient combustion.

  • Patent number: 5440966
    Abstract: A material hand-off mechanism and process which utilizes a pendulating arm to deliver material to and or accept it from a load station which cooperatively engages the arm. The load station and the arm provide interceptive, interactive and linkless conveyance capable of independent and parallel operations to enhance efficiency and availability of the system. Particularly, the mechanism is suited to transfer ammunition from a storage station into a gun tube. The ammunition is rammed into the gun breech using a flick ram mechanism, which operates in cooperation with the arm, and enables a sure ram of ammunition comprising different modules.

  • Patent number: 5403384
    Abstract: In a regenerable collective protection system the turbine of an air cycle machine is driven by a potion of the clean air output of a pressure swing adsorber bed pair in the system. The beds in the pair are used alternately to cleanse contaminated air. They are then alternately purged of contaminant products. Valves are used to direct these alternate operations. The valve closures cause overpressures in the clean air output. The overpressures are predictable in relation to the valve actuation sequence and are removed by coordinating operation of a surge air bleed valve in the clean air output with valve actuation in the pressure swing adsorber bed pair.

  • Patent number: 5402703
    Abstract: The invention provides a three layer liner for armor to reduce spall and the spall angle. The liner provides a high impedance.The liner is formed by layers of silastic rubber with tungsten powder. Successive layers have a decreasing concentration of tungsten powder, causing the density of the successive layers to decrease. This decreasing density causes the high impedance of the liner. The liner is made by casting a layer of the silastic rubber with the tungsten powder mixed in with a second layer of silastic rubber with a lower density of tungsten powder. The material is then pressed into a sheet. One side of the sheet is wet with silastic rubber and merged with a fabric layer.

  • Patent number: 5373734
    Abstract: A method and apparatus for measuring the quality of a coating on a plate. The invention uses a method of measuring the impedance of a coating on a plate, which uses the steps of placing the coating on a plate in a chamber, and then placing a counter electrode in the chamber so that the coating lies between the plate and the counter electrode. A reference electrode is placed in the chamber so that the coating lies between the reference electrode and the plate, and the chamber is filled with a fluid with an ionic substrate. A potentiostat induces a voltage between the plate and the reference electrode, and the impedance of the coating is measured to determine the quality of the coating.
