  • Patent number: 5016440
    Abstract: Apparatus is provided for delivering a controllable, variable flow of pressurized fluid. Conduits define a circulating fluid flow system, the flow system passing through a transducer for transferring energy as a mechanical input or output to or from pressurized fluid circulating in the system. At least first and second volumetric pumps are connected to conduits of the flow system in parallel relation to each other and in flow communication with the transducer. An operating shaft, preferably a single shaft, engages the first and second pumps. Valves and piping are provided for selectively shunting and isolating the first and second pumps from the fluid flow system. Thus, energy applied to the fluid flow system through either the shaft or transducer may be applied to the other of the shaft or transducer with variable pressure and flow velocity in the flow system, depending on whether one or both of the pumps are in operating mode with the flow system.

  • Patent number: 5011031
    Abstract: A rack which comprises a pair of parallel side beams in which each defines a groove facing the other side beam. The rack may be made by inserting between the beams at least one crossbar with the opposed ends of the crossbar each occupying a facing groove of the side beams, and with the crossbar extending between the beams. One may flex the beams outwardly as necessary to insert the crossbars. One then inserts between the beams a spacer bar, positioning the spacer bar centrally along the beam, with the opposed ends of the spacer bar each occupying a facing groove of the beam, and with the bar extending between the beams. The spacer bar is shorter than the crossbar. Thus, upon tightly securing each side beam to an end of the spacer bar, one draws a central portion of each beam inwardly relative to the crossbar or crossbars, to provide high constricting pressure securance between the ends of the crossbar and the side beams, while the spacer bar is under tension.
