Patent CA-1125092-A (CA)
Inventor: GRENNAN CHARLES W
IPC: F04D15/00
Filed: 1978-11-07
Granted: 1982-06-08
Abstract: ABSTRACT OF THE DISCLOSURE     An axial inducer, which charge the inlet of a centrifugal impeller has a bypass loop connecting its inlet and outlet.  A valve member for controlling bypass flow is positioned in the bypass loop.  At low flows, the bypass loop permits the inducer to run closer to design flow conditions than would otherwise be possible and, consequently, generate less pressure rise, consume minimum power, and cause minimal heating of the fluid being pumped.           An extension of the bypass valve member functions to restrict the centrifugal pump discharge area when the valve member is positioned to bypass flow to reduce recirculating flow in the centrifugal impeller and increase its efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE         An emergency light entirely self-contained that fits into a standard AC fixture in place of a fluorescent or other vapor lamp employs a similar lamp and a rechargeable battery with a system which operates the lamp normally on AC but if AC power fails operates the lamp using battery power.  During normal operation on AC the battery is charged by a rectifier charger unit operating in series with the lamp current, which limits battery charge current.  When AC power fails the lamp is electrically isolated from the AC line and operated by an inverter unit drawing power from the battery.

Abstract: ABSTRACT OF THE DISCLOSURE         A switch which is opened and closed by success-ively depressing a manual operating handle is provided with one spring for separating the switch contacts and a separate spring for closing the switch contacts. In-terrupting capacity is improved without increasing over-all size by utilizing a J-shaped movable contact arm mounted on a pivot located a substantial distance from the movable contact.  The closing spring is located ad-jacent to the arcing or interrupter area.  A metal shield is positioned to protect the closing spring from hot arcing gases as they exit from the interrupter area. The speed of instantaneous or magnetic tripping is im-proved by providing the against coil with at least one complete current carrying loop.

Abstract: ABSTRACT OF THE DISCLOSURE                 A fuel injector valve has a nozzle housing with a bore therethrough having an outlet end in communication with a cylinder of an internal combustion engine.  The bore has a seating surface at its lower end which seats an annular ring.  The annular ring has a central aperture therethrough with a seating surface at its lower open end.  The aperture receives a plunger sized to leave a space between the edges of the aperture and the plunger surface.  The plunger has a flanged lower section and is spring biased upwardly to have the flanged lower section contact the seating surface of the ring.  The upward biasing force also forces the ring to abut the seating surface of the nozzle housing.  The fluid under pressure enters the nozzle housing and forces the plunger and annular ring downward.  Fluid passes through the passage between the floating ring and nozzle housing and also between a second passage between the floating ring and plunger so that a spray pattern with a cross-section of two concentric rings is formed entering the engine cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE          A dock leveller is disclosed which has provision for automatically raising dock leveller lip as dock leveller ramp is elevated and for automatically returning clock ramp to raised position preparatory for lowering to a supported cross-traffic position. The dock leveller comprises a ramp pivoted at its rear portion on a support frame, means for biasing the ramp for upward swinging movement, releasable means for retaining the ramp against upward force of the biasing means and a lip pivotally connected at the ramp's forward portion.  The support frame has means which supports the pendent lip to support the ramp in cross-traffic position.  The lip is also adapted to support the ramp by resting on a vehicle bed to bridge vehicle bed and dock and the lip falls towards its pendent position when a vehicle moves away. Means automatically releases the retaining means as the lip unsupported fall is interrupted by means.  Such automatic release means re-engages the retaining means as the ramp rises to permit the lip to clear the interrupt means and fall to its pendent position preparatory to lowering the ramp to its safe supported cross-traffic position.  The dock leveller may also have means which transmits a forward pivotal movement of a portion of a member for raising the ramp from a lowered to raised position which in transmitting such pivotal movement to the lip, raises the lip to its extended position.

Abstract: ABSTRACT OF THE DISCLOSURE "Curved array of sequenced ultrasound transducers".          An array of ultrasound transducers for pulsed sector-scan operation includes a plurality of transducer elements disposed on an arc of a circle and oriented to emit and receive ultrasound radiation in the direction of the center of the arc. A group of adjacent transducers within the array is active for each ultrasound pulse. The position of the group in the array is incrementally shifted along the arc, one transducer at a time, to effect scanning. The inherent focussing effect of a curved group of transducers is compensated with time delays or a negative lens to provide a parallel, sector-scanned radiation beam.         The array may be manufactured by cutting grooves in a solid bar of piezoelectric ceramic and bending the grooved bar around a mandrel to separate individual transducer elements from each other.
