  • Patent number: 5290010
    Abstract: A multiple thrust range, live loaded packing system for stems and shafts extending into a packing chamber containing a packing ring, and a packing gland engaging the ring and having an outer end portion projecting outwardly of the chamber includes a first thrust member engaging an outer end portion of the gland and a second thrust member spaced from and facing the first thrust member. A spring is mounted between the thrust members for normally biasing the thrust members apart and a spacer is mounted between the thrust members around the spring for establishing a minimum spacing distance between the thrust members. One or more tension members extend between the thrust members to secure the thrust members against the spacer for exerting a selected live load on the packing gland via the spacer, the spring and the first thrust member.

  • Patent number: 5275405
    Abstract: A floor air vent cover includes a centrally located closed bottom depression the size of a putting cup for receiving and retaining a putted golf ball. The opposite ends of the cover contain air passage openings having tapered sides for directing the air flow away from said depression.

  • Patent number: 5192049
    Abstract: A dual rated live loaded packing system for a valve stem includes at least one thrust load assembly extending between opposing facing elements on a valve body and a packing gland, respectively, for exerting a live load through a gland onto a packing ring contained in a packing chamber around the stem. The thrust load assembly includes an elongated tension member engaging a first one of the ears at one end and a second of the ears at an opposite end. An adjustable nut is threadedly engaged on the tension member having an end facing a surface on the second ear. A spring element is mounted on the tension member between the nut and the second ear for biasing the nut away from the second ear. A cylindrical spacer is mounted on the tension member enclosing the spring element for setting up a minimum value space between the nut and the second ear.

  • Patent number: 4344285
    Abstract: A signal bleed-down valve in a load responsive system which is positioned in the sensing line between the pump compensator and control valve. The valve in the absence of sufficient pilot pressure opens the pump compensator to drain. Otherwise, the valve is controlled by pilot flow across a fixed orifice in the spool which creates a pressure drop acting against a spring, and moves the valve spool to a position metering the pilot flow so as to maintain a constant flow level across the valve spool regardless of the pressure level.

  • Patent number: 3996744
    Abstract: An automatic control for reducing a flow pressure compensated variable displacement pump to a standby condition while the pump operated motor is lowering a heavy static load. The pressure in the motor exhaust line caused by the static load actuates the control to cut-off pressure to the downstream sensing line of the pump flow control. A bleed orifice in that downstream sensing line depressurizes the line causing the pump displacement servo to stroke back the displacement of the pump to a standby condition.
