  • Patent number: 7191957
    Abstract: A peristaltic depositing machine includes a hopper to store viscous material. A flexibly deformable tubing section is connected to the hopper for receiving the viscous material. A pair of rollers cooperate to compress tubing section and thereafter move forwardly along the tubing section such that the viscous material is forwardly propagated. A manifold is connected between the hopper and the tubing section to transmit the viscous material there between. A flow control unit is connected to a portion of the tubing section forward of the pair of rollers. The flow control unit alternately constricts and unconstricts the portion of the tubing section in synchronism with the forward movement by the pair of rollers. A nozzle is connected to an output end of said tubing section to shape the viscous material upon output. A carriage is also connected to an output end of the tubing section and moves about a predetermined travel path to thereby direct an output location of the viscous material.

  • Patent number: 6981654
    Abstract: Valve for the periodic and cyclic or otherwise intermittent release of a fluid is described along with an irrigation sprinkler incorporating the valve. The valve opens when a critical pressure level is reached in a reservoir attached to the valve, thereby permitting a portion of the fluid contained within the reservoir to be released through the valve. As the fluid is released, the pressure in the reservoir decreases. The valve does not close until the pressure level in the reservoir reaches a second pressure level that is below the critical pressure level. When the reservoir is refilled from a pressurized source at a controlled rate that is less the rate at which the fluid is expelled through the valve when open, the valve will cycle repetitively.

  • Patent number: 6796273
    Abstract: The present invention relates to a water director for distributing a surge or flow of water to one or more of a plurality of output ports, which can vary in shape, size, and number, typically for use in marine and fresh water aquariums. Water pumped through a conduit into the hermetically sealed Switching Current Water Director (SCWD), powers an internally mounted gear driven fluid motor, which turns a rotational valve, alternately opening and closing a plurality of water outlet ports. When mounted externally to an aquarium, proper placement of output nozzles, which are connected to a water conduit attached to the various SCWD outlet ports, provides the desired opposing, or switching back and fourth currents. Depending on the inlet and outlet port configuration, the SCWD can be adapted to suit many applications.
