  • Patent number: 6748967
    Abstract: Couplers for joining actuators to valves are configured to allow their affixment to different makes and models of actuators and valves, thereby allowing an off-the-shelf S coupling solution and avoiding the need to specially construct a coupler which is only adapted to connect whatever valve and actuator that are desired for coupling. The couplers include a shaft/stem bore which accommodates the torque-transmitting components of the valve and actuator to be coupled, and sets of affixment holes surround the shaft/stem bore, with these affixment holes being arrayed in patterns matching those of different common valves and actuators. Thus, a coupler may affix to different valves or actuators provided the appropriate affixment holes are chosen. The couplers may be formed as single-piece or multi-piece units.

  • Patent number: 6745791
    Abstract: Pipeline stopping tools for use in temporarily stopping flow in a pipeline have features for centering a conduit or cable within the pipeline. The conduit or cable is guided into a recess, to avoid damage as the pipeline is squeezed closed. Alternative pipeline stopping stools have features for sealing against both the inside walls of the pipeline and against the cable. In a first tool, a linkage on a handle drives seal lips on a seal ring to engage around and seal against the cable in the pipeline, while the outer edges of the seal ring seal against the inside walls of the pipeline. The linkage includes jaws which force the seal lips against the cable. In a second tool, a resilient seal is attached over a center plate and side plates pivotably attached to the center plate. A linkage drives the center plates from an open to a closed position. A cable recess in the seal ring seals against the cable while the outside edges of the seal ring seal against the pipeline.

  • Patent number: 6722386
    Abstract: The present invention provides a flow control apparatus and method. In accordance with the present invention, the flow control apparatus comprises a thermostat that automatically actuates valve to enable water to flow through the valve when the temperature of the air or water is at or near the freezing temperature of water (32° F.). When the temperature of the air or water rises above freezing, the thermostat causes the valve to close, thereby preventing water from flowing through the valve. Therefore, when the apparatus is coupled to an end of a water conduit, such as a water spigot or hose, water is allowed to flow through the conduit when the air or water temperature is at or near freezing to prevent the conduit from bursting due to water freezing and expanding within the conduit.
