    Abstract: A terminal reversing block mounts to a standard electrical disconnect device such as a circuit breaker or a pullout switch. The disconnect device has a housing which defines a cavity that faces in one direction for receiving a cable. Front and rear contacts are in the housing, one of which extends into the cavity for engagement with a cable. A terminal reversing block has a housing with at least one pocket which faces in a direction other than the opposite of the direction in which the disconnect device's cavity faces. A terminal collar disposed in the terminal reversing block pocket is engageable with a cable inserted into the pocket. A terminal in the reversing block has a mating portion and a connecting portion. The connecting portion engages the terminal collar. The mating portion engages one of the front and rear contacts of the electrical disconnect device. The arrangement of the directions in which the cavity and pocket face permits routing of the cables to minimize space requirements in a confined area, such as an enclosure or a cabinet.

    Abstract: A constant-flow drip irrigation tape hose includes a primary flow path communicating water along the length of the hose. A secondary drip-flow path leads from the primary flow path to an emitter site outwardly of the hose. The hose is formed with a pair of variably spaced apart walls at least one of which is formed with a continuously-open channel defining part of the secondary flow path. A second variable-area part of the secondary flow path is defined by radial spacing of the pair of walls from one another. At least one of the pair of walls is responsive to internal water pressure in the primary flow path to open and close the variable-area part of the secondary flow path in response, respectively, to decreasing and increasing water pressure in the hose. A plurality of emitter sites are spaced regularly along a length of the hose. Consequently, the hose has at least one pressure range within which it provides a nearly constant drip-flow irrigation rate to plants of a row crop as the water pressure within the hose decreases over the length of an elongate run of hose.

    Abstract: The improved pitot tube is useful in pitot type centrifugal pumps and is located within a rotor in the pump. The pitot tube projects radially from the axial center line of the pump and has an entry adjacent to the inside of the wall of the rotor. The entry is oriented circumferentially to receive fluid energized by the rotor. The pitot tube has a passageway therethrough which extends from the entry to an outlet located on the axial center line of the pump. Between the entry and outlet there is provided an entry transition portion that is curved to change the direction of flow from centrifugal to radial, a radial portion, and an outlet transition portion that is curved to change the direction of flow through the passageway from radial to axial. Located in the passageway are one or more ribs or vanes which are curved through the entry transition portion of the passageway and extend into the outlet thereof. The ribs provide for streamlining the flow to avoid turbulence to decrease the internal drag in the passageway and also to reinforce the pitot tube so that the walls thereof may be made substantially thinner whereby outside width of the tube can be decreased to reduce the external drag loss.

    Abstract: A rotary gas/liquid separator includes a housing having a free running rotor mounted to rotate about a vertical axis in the housing. The rotor has an inverted conical inside surface, and a plurality of turbine blades adjacent an upper end of the conical inside surface. A gas/liquid inlet mixture is forced under pressure through stator vanes for directing flow of the inlet mixture tangentially into the turbine blades for rotating the rotor. The turbine blades divert the inlet mixture radially outwardly and then axially downwardly toward the conical inside surface of the rotor, and centrifugal force exerted on the inlet mixture by the rotating turbine blades separates liquid from the gas in the inlet mixture. The separated liquid flows downwardly in a thin film along the inside surface of the rotor and drips from a free lip at the bottom of the rotor for collection. A plurality of fan blades on the rotor discharge separated gas from a first chamber below the rotor to a second chamber above the rotor. A substantial pressure drop and corresponding adiabatic cooling of the gas results from passage of the gas through the turbine blades, and the fan blades increase the pressure and temperature of the gas in the second chamber relative to gas pressure and temperature in the first chamber.

    Abstract: An improved diffusion bowl and pumping vanes of a centrifugal pump stage are employed in axially stacked, multi-stage pumps for use in oil wells. The wall thickness of the annular casing portion of the diffusion bowl element is reduced to a minimum consistent with the axial loading on the pump stage and the impeller vanes are radially extended to terminate closely adjacent the minimum wall thickness portion of the casing, thereby significantly increasing the pumping pressure developed by the stage without reducing the efficiency of the stage.
