  • Patent number: 4137946
    Abstract: A lock screw arrangement for a lateral passage which intersects the longitudinal bore of a pressure vessel, wherein the lateral passage includes a first shoulder facing toward, a second shoulder facing away from the bore, includes a shaft for extending through the lateral passage with threads intermediate the inner and outer shaft ends. The inner shaft end is formed to provide a surface for engaging a member to retain it in the bore and an annular shoulder facing the first shoulder within the lateral passage. Packing abuts the second shoulder and surrounds the shaft. A nut is externally threaded for engaging with threads in the internal passage, and internal threads for engaging with the threads on the shaft whereby the nut may be engaged against the packing to seal between the passage and shaft.Seal means are carried by the nut for engaging adjacent the outer shaft end to isolate the internal nut threads and shaft threads from the environment and from internal pressure in the vessel.

  • Patent number: 4122557
    Abstract: The specification discloses an incinerator toilet having a seat mounted on a heat insulated bowl with an upper tapered baffle in the bowl extending down to a lower tapered baffle. A fuel nozzle from a fuel pump injects fuel chordally into the space between the lower baffle and the bowl past a spark plug, which ignites the fuel, air being blown in with the fuel by a lower blower having an outlet coaxial with the nozzle. A second blower blows air into an annular passage at the upper end of the bowl, and this air travels into and down the upper baffle. The air and the products of combustion are exhausted through an exit port through the bowl positioned above the lower baffle. When a cover is placed in the opening to close a limit switch and a push button is held closed, an igniter circuit, the fuel pump motor and the lower blower are energized. If flame is present, the circuit is locked in by a timer and the upper blower is energized.

  • Patent number: 4123069
    Abstract: A mechanical sealing device for use with a rotary shaft extending through stationary casings. In this sealing device, first and second stationary ring members are arranged in surrounding but concentric relation to the rotary shaft, with a resilient bellows interposed therebetween, and a rotatable ring member is fitted on the rotary shaft. The first ring member is affixed to one of the casings while the second ring member is urged against the rotatable ring member by means of the resilient bellows in sliding relation thereto. A plurality of radial passages are defined in the rotatable ring member, so that cooling medium may be fed in the radial passages for cooling the rotatable ring member rather than sprayed over the surface of the rotatable ring member. In addition, the rotatable ring member is formed with an annular lead-in or guide portion having inner and outer conical peripheral surfaces for smoothly admitting injected cooling medium in the radial passages provided in the rotatable ring member.
