Abstract: A fluid fuse is operable to shut off fluid flow only when a certain predetermined volume of fluid has passed through in a single operative cycle. This can then be reset by dropping the inlet pressure. The device protects a hydraulic system from line rupture while automatically resetting after every routine operative cycle when less than the predetermined volume flows. A cylinder has a large diameter bore portion and a small diameter bore portion and holds a sliding piston with large and small diameter segments sealed to respective bore portions by sliding seals. An annular fluid chamber between the seals is reduced in volume as the piston, during fluid flow, moves from a reset position toward a closed position. In the closed position a valve member at the end of the small diameter segment seals off fluid flow as it engages a valve seat at the outlet. Fluid from the annular chamber passes to the outlet through an axial passage in the piston so that the piston may advance.

Abstract: A dual inline double acting plunger arrangement is particularly adapted for pumping thick slurries and includes a hollow cylinder divided into two closed chambers by a partition. A first plunger is disposed in a first chamber and a second plunger is disposed in a second chamber with the two plungers coupled together by appropriate linkage outside of the cylinder. A drive mechanism connected to the coupling linkage simultaneously displaces the two plungers in a reciprocating manner within the two chambers. Inlet and outlet ports in each of the chambers coupled to inlet and outlet valve assemblies allow for the pumping of a slurry from the chambers by the two plungers in an alternating manner. Each valve assembly includes a housing having a pair of ball valves which are both employed either as inlet valves or outlet valves, as the valve assembly may be configured to perform both functions.

The separated portions of the conduit can be rotated to adjust the outflow direction. Preferably, an infinite number of outflow directions are possible, all of which lie in a plane parallel to the inflow direction.

Abstract: This invention relates to a fluid distribution manifold, where the input piping is inserted in through the manifold's circular intake opening and onto its cylindrical input port. The manifold's intake opening leads through a cylindrical path to a closed terminal end.

The manifold has the further utility of being expandable to larger sizes. This is achieved by removing the closed terminal end from one manifold and then inserting and connecting that open terminal end in through another manifold's circular intake opening and into its intake port.

Abstract: An axial flow-type pump for separating immiscible fluids having different specific gravities and a discharge manifold fluid connected to the fluid pump for drawing of the fluid having the heavier specific gravity. The fluid pump employs a rotatable impeller mechanism having a hollow core and a decreasing axial pitch in the direction of fluid flow. The fluid interface between the pump and the discharge manifold is adjustable, so that the discharge of the fluid having the heavier specific gravity can be adjusted. The fluids are introduced into the inlet end of the rotatable impeller to produce a high velocity swirling action in the fluids and a low pressure area along the longitudinal axis of the flow line, to generate a high centrifugal force as the fluids move axially and cause the fluid having the heavier specific gravity to migrate to the perimeter. The discharge manifold is then used to draw off the fluid having a heavier specific gravity.

In this way a limited number of transducers in the housing may be used to successively measure a much larger number of fluid pressure pickup points, by time sharing use of the transducers.
