  • Patent number: 8491720
    Abstract: Embodiments disclosed herein generally relate to an HVPE chamber. The chamber may have two separate precursor sources coupled thereto to permit two separate layers to be deposited. For example, a gallium source and a separate aluminum source may be coupled to the processing chamber to permit gallium nitride and aluminum nitride to be separately deposited onto a substrate in the same processing chamber. The nitrogen may be introduced to the processing chamber at a separate location from the gallium and the aluminum and at a lower temperature. The different temperatures causes the gases to mix together, react and deposit on the substrate with little or no deposition on the chamber walls.

  • Patent number: 6533557
    Abstract: This invention relates to a positive displacement pump which allows a liquid additive (such as liquid fertilizer) to be introduced into another liquid stream (such as water) and to be mixed in a constant proportion. One end of the pump can be connected to a faucet and the other end to a typical garden hose or other device. Water enters the pump through a faucet and is redirected (bent) by an upper stator which allows the water to rotate turbine vanes. The turbine is rotatably connected to a cam and the rotation of the cam moves pistons which allows liquid fertilizer to be drawn in from its reservoir. The liquid fertilizer flows through a tube and into one of two pistons. Then, the liquid fertilizer is dispelled through one of the exit tubes through the pumping action of the pistons. The water which was used to turn the turbine then combines with the liquid fertilizer as it comes out of the exit tubes and a water/fertilizer mixture is created.

  • Patent number: 6269851
    Abstract: In the case of a filling pipe for a fuel tank a branching element is arranged in a section of the filling pipe. The flow of the inflowing fuel preferably runs along an outer wall of the filling pipe, so that a subflow is in each case conducted directly to the antisurge tower through a lower cross-sectional area. Larger volume flows, which completely fill the cross section, pass for the most part directly into the fuel tank. By this means, a sufficient basic supply of the antisurge tower is ensured irrespective of the volume flow produced during filling.

  • Patent number: 6158485
    Abstract: In the case of a filling device for a motor vehicle fuel tank, a distributing element extends from a filling nozzle to an anti-surge tower of the motor vehicle. When there is a low volume flow of fuel in the filling nozzle, the distributing element supplies all of the fuel to the anti-surge tower. When there is a large volume flow, the greater part of the fuel passes directly into the fuel tank. It is thereby ensured that during an initial filling or emergency filling with a jerrycan, virtually all of the fuel passes into the anti-surge tower.

  • Patent number: 5726404
    Abstract: This invention provides a valveless method and apparatus for high speed switching of liquid flow between intersecting microchannels. Liquid flow is controlled by manipulating external driving pressures. The switch comprises three intersecting microchannels, each having a liquid reservoir at its nonintersecting end for liquid inlet and outlet. It further includes applying a driving pressure to each reservoir switching the driving pressures. The microswitch of this invention operates to establish a liquid flow from a first channel to a second channel by applying a pressure differential between the first and second reservoirs, while simultaneously preventing flow into the third channel by applying a pressure to the third reservoir which equals the pressure at the junction of the three channels. By switching one or more driving pressures, the flow to the second channel can be stopped and the liquid flow redirected to the third channel.

    Abstract: A plurality of water injection nozzles (16) are spaced around the tub (12) of a hydrotherapy spa (10) for injecting a pulsating flow of water and air into the main body of water (14) in the tub (12). The pulsation is produced by a distribution valve (30), (80) including rotor (46) , (92) which is rotated by the inlet water flow and distributes the inlet water to outlets (40,42,44), (90) which are connected to the nozzles (16) respectively. The rotor (46), (92) is formed with a groove (48), (96) which sequentially aligns with and connects the outlets (40,42,44), (90) to the inlet (34), (86). Since each outlet (40,42,44), (90) is periodically connected to and disconnected from the inlet (34), (86), the water is supplied to each nozzle (16) in a pulsating or chopped manner. The sequence in which the water is distributed to the nozzles (16) is fixed, enabling a rippling effect to be produced in which the pulsation appears to rotate around the spa (10).

    Abstract: A device and method for automating immunohistochemical staining of biological material on glass slides is presented. The slides are placed on a base with the tissue section facing upwards. A "chamber" consisting of a rectangular plastic box with a hinged overhead door is clamped directly over the tissue section. A rubber gasket seals the chamber--slide interface. Reagents are dropped on to the tissue section by opening the hinged overhead plastic door. When the door is closed, the chamber is sufficiently sealed so as to prevent evaporation. Washing of the tissue section is accomplished by the addition and aspiration of buffer through ports in the chamber. The ports are connected via flexible tubing to a manifold. Because the wash steps are peformed in tandem and do not require manual manipulation of slides, a significant time savings is realized.
