  • Patent number: 5647265
    Abstract: A system including a cutting tool is provided for cutting a round strand m a soft, rubber-based material. The cutting tool comprises a tube having an inner and an outer surface which form a sharp leading edge. The tool further comprises a blade which fixedly attaches to the outer surface of the cutting tube. The blade has a wedge-shaped leading edge and a circular-shaped arc on its bottom end for receiving the tube. A handle for the blade attaches to the top end of the blade. The system for cutting a round strand from a soft, rubber-based material also includes an arbor support arm, a vacuum chuck plate, and a horizontal milling machine having a numerical control. The arbor support arm connects to the handle of the cutting tool. The arbor support arm in turn connects to the horizontal milling machine. The vacuum chuck plate also connects to the horizontal milling machine at a table. The vacuum chuck plate has a cylindrical pin which extracts any round strands stuck in the cutting tube.

  • Patent number: 5636180
    Abstract: Acoustical shock waves are generated by electrical sparks within a gap between electrodes adjustably positioned for exposure to water adjacent a surface immersed therein. High voltage electrical energy derived from a constant current power supply, is stored in a capacitor for rapid. application to the electrodes by discharge during cyclic periods of short duration under remote control in order to render the acoustical shock waves so generated effective in preventing biofouling of the surface by organisms in the water.

  • Patent number: 5602434
    Abstract: Axial elongation of a magnetostrictive element during a power phase of option in a motor, effects conversion of axial force to a torque applied to a rotor through cam discs held in axial engagement by a clutch disc during axial force transfer. Rotor rotation by such torque angularly displaces the cam discs relative to each other against the bias of a spring device during the power phase, followed by a free-wheeling phase during which axial withdrawal of the clutch disc occurs in response to contraction of the magnetostrictive element and angular restoration of the cam discs to a limit position under the spring bias.

  • Patent number: 5600239
    Abstract: A magnetostrictive element having a large magnetomechanical coupling factor long its axis, is selected to determine strain by measurement of changes in its electrical impedance along such axis. Such measurement is maximized by generation of current of a predetermined frequency conducted through the magnetostrictive element to correspondingly penetrate the magnetostrictive element to a substantial skin depth.

  • Patent number: 5594195
    Abstract: The blocking disc serving as an explosive train interrupter of a safety and rming mechanism is angularly displaced from its safe position by a stepping motor through reduction gearing in response to timed energizing pulses applied thereto from a crystal-controlled pulse generator. The blocking disc is releasably latched in its safe position by a locking rod controlling the supply and cut-off of energizing voltage to the pulse generator to accurately time displacement of the disc to an armed position.

  • Patent number: 5550789
    Abstract: A Doppler shift flow meter array detects turbulence in the wake of a submne. Three sets of transmitting and receiving sonic transducers are spaced in a line on a rigid support. The transmitting transducers emit ultrasonic energy which is reflected from particulate matter in a surrounding water medium. The reflected energy is detected by the receiving transducers. A digital Doppler meter associated with each set of transmitting and receiving transducers develops a digital count over a fixed interval that is equal to the Doppler shift between transmitted and received energy. First differences between adjacent pairs of digital Doppler meters are obtained by two digital subtractors, and the second difference between Doppler shifts is obtained by a third digital subtractor. The second difference is non-zero only when ocean turbulence is present, such as produced by a submarine.

  • Patent number: 5532589
    Abstract: A magnetic field generator positioned externally of a non-ferrous metallic tructure being examined, is rotated at a relatively low speed to produce a rotating magnetic field penetrating the metallic structure to a selected depth as a function of spacing between magnetic poles of the generator parallel to a planar surface of the metallic structure. Traction between the metallic structure and the magnetic field accompanying its rotation is measured. Corrosion of the metallic structure at subsurface depths is detected and quantified from such traction measurements.

  • Patent number: 5515783
    Abstract: Ignition current is conducted by a firing circuit through a firing pin to a rimer mixture retained by its cap within a cartridge case from which the cap is electrically separated by an insulator to effect primer ignition with reduced lock time by activation of a firing switch independently of the firing pin. Voltage for the firing circuit is derived from a battery, maintained in a charged condition by alternate voltage supply sources, and stored at an ignition firing level for a prolonged period of time to accommodate selective activation of the firing switch after the firing pin contacts the primer cap.

  • Patent number: 5515300
    Abstract: A signal detection system divides a data sampling run into blocks and perms a fast Fourier transform on each block, sorting results by frequency. Combinations of results of the fast Fourier transform corresponding to each frequency are processed to derive a test statistic which is unbiased by Gaussian noise while including such combinations of results of the fast Fourier transform which would be redundant over other combinations. Information concerning the frequency behavior of the signal derived in the course of detection, is accomplished with increased sensitivity.

  • Patent number: 5483410
    Abstract: The static magnetic field signature of a sea-going vessel is reduced by sly of degaussing current to pairs of loop coils adjacent to the port and starboard sides of the vessel hull. The coils of each pair are positioned at equal angles to a vertical plane extending longitudinally along the keel of the hull. The degaussing currents in the respective coils of each pair are simultaneously varied with respect to amplitude and polarity in accordance with geometrical heading of the vessel and changes in its roll and pitch orientations.

  • Patent number: 5478532
    Abstract: A weakly ionized plasma is generated by continuous high-power microwave win a dielectric cavity positioned in a slow waveguide. Contaminated air under atmospheric pressure is exposed to the plasma within the waveguide cavity for a limited saturation time controlled by inflow at a regulated flow rate. During such limited saturation time, the contaminated air is purified by sequential ionization and recombination under an electron temperature resulting in a microwave discharge plasma dominated by atomic oxygen at a relatively high saturation density level together with atomic nitrogen at a relatively low density level.
