  • Patent number: 5660198
    Abstract: A control system is provided for monitoring and regulating fluid pressure at a remote and/or potentially hazardous location along the length of a fluid flow conduit, without requiring a pressure sensor device at the remote site. The control system comprises a controller responsive to fluid pressure and flow rate readings taken at a convenient and/or safe location along the length of the flow conduit, to derive fluid pressure at the remote site. The controller provides a display of the derived pressure and/or operates a control valve at the safe site to regulate the pressure at the remote site.

  • Patent number: 4742843
    Abstract: An air and vacuum relief value having a cylindrical housing defining a chamber and an aerodynamically shaped float body disposed for movement within said chamber between a lower, open position and an upper closed position, the float body having a generally inverted pear-shape configuration to prevent premature valve closure.

  • Patent number: 4735365
    Abstract: An improved irrigation boom assembly is provided for relatively rapid and easy mounting onto the main water distribution pipe of a traveling irrigation system, particularly such as a center pivot or linear travel system. The improved boom assembly includes a water supply drop pipe adapted for rapid and secure mounting onto the main distribution pipe by an improved clamp assembly and for receiving water from the distribution pipe via a flexible feed hose. The drop pipe has a manifold at its lower end designed for facilitated connection to a lightweight boom comprising a pair of elongated wing tubes cantilevered outwardly therefrom in opposite directions, wherein the wing tubes are each supported in an adjustably selected geometry by a respective pair of support cables anchored between the drop pipe and the wing tube and threaded through support struts mounted at spaced intervals along the wing tube spans. The outboard end of each wing tube includes an easily removable end fitting to permit periodic flushing.

  • Patent number: 4491145
    Abstract: A toggle gate valve having a double block and bleed retractable sealing configuration which utilizes accurately positioned steel inserts as trim assembly guide plates to permit a significant reduction in valve body machining. The valve body as well as removable upper and lower bonnets form a pressure boundary that houses a toggle link actuated seal plate to close the valve and a through-conduit that is coaxially aligned with the input and output ports when the valve is opened. A novel stem configuration and removable through-conduit permit field servicing of the trim assembly (plug and seal plate) by means of access through the lower bonnet/body interface.
