摘要： A centrifugal pump of the pitot pump type is provided a stationary vane structure containing a pitot tube mounted inside a rotating casing. Fluid is delivered to a pumping chamber within the casing through a plurality of radially extending ducts of at least two disparate radii in the wall of the casing which discharge fluid by centrifugal force into the casing. The disparate radii of the ducts induce inward fluid circulation in the shorter ducts and outward circulation in the longer ducts which improves the low flow-pressure characteristic of the pump. An air extraction tube provides communication between the central portion of the pumping chamber and the inlet of the radially extending ducts to provide for the extraction of air from the interior of the pumping chamber to further improve the pumping efficiency.

摘要： A method and apparatus are provided for automatically and continuously balancing the unbalanced thrust resulting from the operation of a fluid pump which is driven by a fluid pressure motor. A hydrostatic-type thrust bearing is employed on the common shaft of the fluid pump and motor by applying pressures to opposite sides of the circular flange of such hydrostatic thrust bearing to compensate for any unbalance in thrust occuring during operation of the pump without requiring any axial movement of the hydrostatic thrust bearing flange. Because of the lack of flange movement, the thrust bearing operates with a constant fluid film thickness.

摘要： A high current, low voltage, load-break switch of the type which is installed in a housing having an access door. The switch comprises a fixed contact, a movable contact which is movable between a closed position in bolted pressure contact with the fixed contact and an open position which is displaced from the fixed contact. A mechanism is provided for rapidly opening and closing the switch by driving the movable contact to its closed position and also to its open position. A transparent shield is supported across the front of the switch contacts to visually expose the switch contacts when the access door to the housing is open while providing protection in the event of electrical arcing and mechanical failure of the switch contacts.

摘要： A gas compressor of the pitot type is equipped with means for separating liquid, entrained in supply gas to be compressed, from the supply gas prior to introduction of the supply gas into a pumping chamber within the compressor. A rotary casing is mounted for rotation in a selected direction about an axis of the compressor. A gas supply passage, for delivering a gas to be compressed, has an outlet to the interior of the casing. A compressed gas discharge duct leads from the compressor coaxially with the casing. A pitot tube extends radially from the compressor axis in the casing and has, adjacent its outer end, an inlet which faces in a direction opposite to the direction of rotation of the rotary casing. The pitot tube has a diffuser passage connected to the inlet and extending toward the casing axis to an outlet port connected to the compressed gas discharge duct. Liquid separating means are cooperatively associated with the gas supply passage upstream of its outlet for centrifugally separating liquid from gas in the supply passage. The liquid separating means are mounted for rotation with the casing.

摘要： A three-phase centrifugal separator for a mixture which may include oil, water, gas and/or solids. A rotor is provided with an inner rotor chamber encircled by an outer rotor chamber, the mixture being delivered to the inner rotor chamber wherein it is centrifugally separated into an inner gas phase encircling the rotor axis, an annular intermediate oil phase encircling the gas phase, and an annular outer water and solids phase encircling the oil phase. Water and solids are discharged into the outer rotor chamber through discharge ports in the periphery of the inner rotor chamber, and are subsequently discharged into an enclosing housing means through discharge ports in the periphery of the outer rotor chamber. A water supply means delivers water to the outer rotor chamber at a rate at least equal to, and preferably considerably in excess of, the discharge capacity of the discharge ports in the outer rotor chamber at a given rotor speed so as to maintain a substantially constant pressure in the outer rotor chamber at such rotor speed. Means are provided for removing oil and gas from the corresponding phases in the inner rotor chamber.

摘要： 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.

摘要： 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.

摘要： 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.
