    摘要: A pumping apparatus comprises a rotatable shaft coupled to a motor. At least one control structure is mounted on the shaft, and at least one impeller is carried by the shaft. The impeller is adapted to rotate independently of the shaft so as to pump a fluid. The apparatus also comprises a magnetic coupling between the control structure and the impeller. Further, the impeller is adapted to translate axially along the shaft in response to a change in downstream pressure to alter the strength of the magnetic coupling.

    摘要: The present invention relates to a method and system for measuring fluid velocity in pipes alternately transmitting two or more ultrasonic frequencies through a pipe wall into a fluid containing scatterers. For each transmission frequency, energy reflected from the scatterers is mixed with the transmission frequency and the result sampled at a rate which is a constant fraction of the transmission frequency. The combination of the Doppler effect on frequencies reflected from the moving scatterers, and the described sampling rate scheme combine to permit isolation of velocity related frequencies from extraneous frequencies in the reflected energy in a computationally efficient manner. A single frequency which represents fluid velocity is extracted from the gathered data, and the fluid velocity readily calculated therefrom using the Doppler formula. The invention provides a system and method for measuring fluid velocity which is simple, reliable, and cost effective.

    摘要: An apparatus comprises multiple electrically conductive loops, an elongated tubular ferromagnetic shield, and an elongated tubular superconductive inner shield. The superconductive inner shield is positioned within the ferromagnetic shield. Each conductive loop includes (i) a thrust segment extending from a first end of the superconductive inner shield outside the ferromagnetic shield to a second end of the superconductive inner shield and (ii) a return segment passing through an interior passage of the superconductive inner shield from the second end of the superconductive inner shield to the first end of the superconductive inner shield. The conductive loops can be spatially arranged relative to a uniform external magnetic field so that interaction between the external magnetic field and electrical current flowing in the conductive loops results in asymmetric magnetic flux density around, and non-zero net force exerted on, the conductive loops.

    摘要: An air pump comprises a cylinder, a piston, a piston rod, three substantially rigid members, and a handle. The piston is reciprocably movable within the cylinder and is secured to the piston rod. The first member is pivotably connected at its first end to the cylinder. The second member is pivotably connected at its first end to the piston rod and at its second end to the second end of the first member. The third member is pivotably connected at its first end to the connected second ends of the first and second members. The handle is pivotably connected to the second end of the third member. The third member is arranged to transmit between the handle and the connected second ends of the first and second members a force resulting from a force applied to the handle.

    摘要: This disclosure relates to the manufacture of lites (glass sheets) which have at least a pair of thin spacers applied thereto which maintain the lites in spaced relationship when stacked upon pallets, wrapped and shipped. The spacers are preferably only partially adhered to the lites, either by weak bonding adhesive or electrostatically, and can be readily removed during end-use applications. The spacers are applied automatically during production runs of the lites, and the spacers are applied from above or from below relative to the path of travel of the lites.
