  • Patent number: 5045288
    Abstract: Means and methods employing gas-solid heterogenous photocatalysis ("GSHP") to counteract the widespread occurrence of groundwater and air polluted by volatile organic compounds (VOCs) such as trichloroethylene (TCE) and non-volatile organic compounds such as polychlorinated biphenyls (PCBs), and the like without creating other environmentally hostile agents. Common treatment methods such as spray tower aeration and activated carbon adsorption, both of which merely convert pollutants into alternate but equally obnoxious forms, can be augmented by the means and methods hereof to create ecologically innocuous byproducts. Heterogeneous photocatalysis allows the complete destruction of those organic water pollutants normally contained in the effluents of existing water treatment facilities. Ambient temperature ultraviolet-illuminated catalyst, such as, titanium dioxide, in the presence of moist air substantially completely destroys trichloroethylene (TCE) type-materials in a gaseous phase.

  • Patent number: 5042361
    Abstract: It is known to arrange a breech mechanism for a gun so as to be displaceable within a parallel guide arranged at a right angle to the bore axis of the gun barrel, and to bring a mushroom shaped head for obturation to the chamber in a partial circular arc. Due to the plurality of drive means for the mushroom head, complicated motion sequences result within the breechblock system which may lead to increased susceptibility to malfunction and do not permit high firing rates. Such a breech mechanism is not suitable or the use of a highly elastic obturator disposed in the gun barrel.

  • Patent number: 5042360
    Abstract: The present invention relates to a regenerative hydraulic starter/speed regulator system for providing initial rotation and acceleration of a rotatable barrel cluster of a gun gas driven Gatling gun, and for controlling the speed of the barrel cluster during the firing of the gun. The hydraulic system includes a high pressure accumulator for containing a supply of pressurized hydraulic fluid. A hydraulic motor/pump unit is connected to either drive or be driven by the barrel cluster, depending on whether the motor/pump unit is operated in either the motoring or pumping mode. Initially, a servo mechanism operates the motor/pump unit in the motoring mode wherein pressurized fluid from the accumulator is supplied to the motor/pump unit to initially rotate and accelerate the barrel cluster in a firing direction until the rotation of the barrel cluster is sustained by the gun gas drive unit.

  • Patent number: 5043953
    Abstract: This pressure compensating device for a volume of immersed gas is equipped with mobile or deformable walls and includes an immersed compensation bladder. The bladder is secured in a housing and communicates with the volume to be compensated. It is arranged by mounting means roughly at the level of the volume. According to the invention, the housing mounting means for the compensation bladder are arranged to allow the housing to move vertically relative to the gas volume so as to keep the mean front of the bladder folds at the level of the surfaces to be compensated, as the volume may be immersed to different depths.The housing mounting means include an arm hinged about a horizontal axis, and a spring exerting its force on a cable connected to the hinged arm.Depending on the preferred application, the mobile walls enclosing volume to be compensated consist of the acoustic drives of underwater electroacoustic transducers.

  • Patent number: 5040449
    Abstract: In a shotgun shell reloader, a manually operated lever drives a carriage reciprocally on a central post for shotgun shells mounted to the carriage to engage with reloading tools arranged on a support which mounts to the upper end of the post. A circular shot plate mounts to the carriage and has a central bore for surrounding the post. An indexer member mounts in the bore of the shell plate and surrounds the post. The indexer has a helical groove in its bore which rides onto a pin extending radially from the post when the carriage is beginning to be raised so that the indexer, which is engaged with the shell plate at that time, turns the shell plate through one angular increment so that a shell on the plate will be presented to tools on the tools support successively to perform the reloading process. A powder bar and a shot bar are mounted to the top of the tool support for moving under a hopper which has chambers for powder and shot.

  • Patent number: 5040465
    Abstract: The invention relates to a projectile for launching and dispersing electromagnetic decoys. The projectile essentially comprises a sleeve which co-operates with a sleeve cap to form a case open at one end. The sleeve contains a decoy carrying piston and is detachably closed by a closure member. The decoy carrying piston comprises shells in the form of cylindrical sectors which keep the decoys arranged in a multi-cell cylinder as long as the piston head is not outside the sleeve. Special shaping of the shells and radical springs produce simultaneous dispersion of all the shells when the projectile operates.

  • Patent number: 5038682
    Abstract: A remote controllable electronic detonator and a method of detonating an explosive charge are disclosed and claimed. The detonator comprises an antenna 16, a RF receiver 15, an energy storage capacitor 17, a switch 18, a delay time circuit 21 and a fuse 19. The method comprises the steps of transmitting to the detonator, by means of transmitter 11, a wave comprising a carrier amplitude modulated by a low frequency modulating signal, receiving the wave and utilizing energy in the wave to charge capacitor 17, enabling switch 18 by increasing the frequency of the modulating signal and communicating, by means of the wave, a fire command signal to the detonator. After a predetermined time delay, switch 18 connects capacitor 17 to fuse 19 thereby to energize the fuse.
