  • Patent number: 6514322
    Abstract: A system for separating an entrained immiscible liquid component from a wet gas stream, the system including a vessel having an interior in communication with a wet gas inlet, a gas outlet and a liquid outlet, at least one vortex tube supported within the vessel interior, the vortex tube having an inlet end and an outlet end and a tubular wall having an internal wall surface through which fluids pass as the gas flows between the vessel wet gas inlet and gas outlet, a vortex generator supported within the vortex tube near the inlet end, the vortex generator causing gas within the vortex tube to rotate to thereby cause at least some of the liquid component to be forced against the interior wall surface of the vortex tube by centrifugal action, a circumferentially positioned liquid outlet in the vortex tube downstream of the vortex generator configured to strip liquid and bypass gas from the stream flowing through said vortex tube, stripped liquid and bypass gas entering a central chamber of the vessel and a rec

  • Patent number: 6474626
    Abstract: A lawn mower rack is formed of a structural base for resting on a support surface. First and second spaced apart longitudinal rails supported by the base and adapted to receive wheels of a lawn mower thereon. A first manually operated lifter is provided for elevationally supporting rearward portions of the longitudinal rails above the base and a second manually operated lifter, independent of the first lifter, is provided for elevationally supporting forward portions of the longitudinal rails above the base so that thereby only approximately one half of the weight of a lawn mower need be lifted at a time.

  • Patent number: 5230437
    Abstract: A viewport assembly having a tubular member, such as a ullage tube, with an internal cylindrical surface, a frame ring with an outer and an inner circumferential surface, the outer surface being defined in part by an outwardly radially extending flange portion and the frame ring having a plurality of spaced apart bolt holes therethrough, a gland ring having an integral forwardly extending tubular portion, the tubular portion being telescopically receivable on the frame ring outer circumferential surface rearwardly of the flange portion and providing an annular area externally of the frame ring between the frame ring flange and the gland ring tubular portion forward end, a transparent window disc sealably received within the frame ring, and a bolt for each of the bolt holes in the frame ring threadably engaging matching threaded bolt holes in the gland ring so that as the bolts are tightened the gland ring is drawn onto the frame ring, compressing the packing ring to expand it outwardly into sealing engagement

  • Patent number: 4854244
    Abstract: A system for use with a rail for carrying a moving conveyance, the rail having a web portion, a base portion and an increased width top portion, the system serving to heat the rail top portion to decrease the accumulation of snow and ice thereon, including studs secured to the rail web portion, such as by spot welding, at spaced intervals along the length of the rail, a series of elongated carrier members each defined in cross-section normal the length thereof by an upper trough forming portion and a lower clamping portion, the clamping portion having openings spaced along the length thereof in register with and arranged to receive the studs affixed to the rail web portion and being positionable in a first position wherein the trough forming portion is exposed to receive a heating cable therein and in a second position wherein the heating cable is in close proximity to the top rail portion whereby heat supplied by the cable is readily transmitted to the rail top portion.
