  • Patent number: 3990476
    Abstract: A rotary control valve which is actuated by a steel bellows mechanism for use in a gas chromatograph. The steel bellows mechanism changes the valve positions as required by the gas chromatograph operation. An improved spring design provides an even pressure to the disc rotating against the valve body as well as allowing this pressure to be varied. Use of steel bellows and the proper materials for construction of the control valve will allow complete installation in the oven of a gas chromatograph for operation at a maximum temperature of 600.degree. F.

  • Patent number: 3977649
    Abstract: A normally closed solenoid operated valve assembly having a poppet movable between a valve normally closed position seating in and closing in orifice and a valve normally open position. A movable armature has a reduced section for engaging and pulling the poppet to the open position. A range spring tends to bias the poppet closed until the upstream force of fluid is sufficient to overcome the spring force. The spring force may be adjusted to vary to a predetermined value the upstream force of fluid. To open the valve, a solenoid is energized to move the armature thereby to move the poppet to the open position.

  • Patent number: 3977427
    Abstract: An apparatus for the control of the viscosity of fuel oil supplied to burners, which comprises, in series, pump means for supplying the fuel oil to the burner system under a selected pressure, means for heating the fuel oil output of the pump means, strainer means and control valve means and orifice means of selected length and diameter. A differential pressure cell monitors the pressure drop across the orifice due to the flow of fuel oil under a selected pressure set by the control valve. Any variations in differential pressure will be due to corresponding inverse variations of viscosity. The variations in the output of the differential pressure cell are communicated to a valve means which controls the amount of steam passing into the heating means, thus controlling the temperature of the fuel oil, and therefore its viscosity, to a proper value.
