Abstract: The present invention relates to a process for imparting anti-bacterial and anti-fungal properties to a polyurethane foam. Dissolving the pyrithione salt in an alkanolamine which is miscible with a polyol, makes this dissolved pyrithione an ideal candidate for use as a antimicrobial additive in this application. Prior use of pyrithiones in polyurethanes entailed using the powder form of zinc pyrithione. This was a dusty process as well as being difficult to disperse the pyrithione uniformly throughout the polyurethane foam. This invention overcomes both of these difficulties.

The housings are characterized by high ductility to resist fracture during assembly or handling. In certain embodiments, one or both lead wires are removed to reduce the potential for lead wire breakage or separation.

Abstract: A process for producing 1,2,4-triazol-5-one reacts a semicarbazide compound with a formic acid compound in the presence of a catalytic amount of a catalyst. The catalyst is selected from the group consisting of an organic sulfonic acid and a sulfonic acid-containing polymer or co-polymer, and mixtures thereof. The novel process of the present invention produces 1,2,4-triazol-5-one having significantly lower concentrations of chloride ion which are advantageous, for example, in the production of 3-nitro-1,2,4-triazol-5-one as an explosive used in castable explosive compositions. The organic sulfonic acid compound catalyst can be recovered and reused.

Abstract: An arcjet thruster is disclosed which has an electrically conductive anode body having an anode cavity therein which defines a nozzle symmetrical about a central axis. The anode cavity has a tandemly arranged divergent recombination portion and a divergent expansion portion. The expansion portion has a greater rate of divergence than the recombination portion. The anode body further preferably comprises a cylindrical constrictor portion upstream and in tandem with the recombination portion. An electrically conductive cylindrical cathode body is coaxially arranged and spaced from the anode body by a gap. An electrical current source connected to the cathode and the anode produces an electrical arc across the gap. A vortex flow of propellant gas is fed through the gap and through the nozzle to produce thrust. The vortex flow of propellant gas pushes the arc through the constrictor into one of the divergent portions of the nozzle.

Abstract: A submunition dispensing system is disclosed which includes inflatable bladders expandable from collapsed to inflated conditions in response to fluid pressure. The bladders are mounted in cavities of a carrier frame underlying subpacks of submunitions. The bladders lie adjacent to the support and central structures of the frame defining the cavities. Each bladder can be configured to have either an unpleated or a pleated configuration in the collapsed condition. The bladder can also be configured for expansion to an overall constant diameter outer shape or to a generally conical outer shape in the inflated condition. Expansion to the conical shape imparts a velocity gradient to the subpack. The dispensing system also includes retaining assemblies for releasably retaining the subpacks in the cavities against the collapsed bladders and a gas generator disposed in a passage of the central structure of the carrier frame.
