  • Patent number: 4957242
    Abstract: The invention is directed to a fluid mixing device in which a jet of first luid is passed through a nozzle having a conical inlet section and a noncircular, elongated, exit section. The jet of first fluid mixes with a second fluid located downstream of the device. In operation, the intersection of the conical and elongated sections produces axial rotation in the first fluid. Intense, three-dimensional, axial and circumferential vortical structures are created. These structures then interact with the high modes of azimuthal instabilities that are common to the elongated configuration. The jet of first fluid evolves into two secondary jets, generating a double shear layer inside the flow. Highly efficient mixing of the fluids, in both the outside and inside (core) segments of the jet, is achieved within a relatively small mixing space.

  • Patent number: 4768533
    Abstract: A closed system paint or varnish stripping apparatus in which the surface finish of furniture and the like can be removed with very little operator contact or maintenance. The system recycles the stripping chemical with only a minimum of filtering being required. Nozzles having an unique design in which the diameter of the orifice is greater than one-half the inside diameter of the supply pipe facilitate spraying the recycled chemical with very little possibility of the nozzles plugging. Moreover, the use of these large orificed nozzles allows the chemical to be sprayed at a high flow rate providing for the drenching of a work piece in several seconds and eliminating much of the mist production and evaporation losses previously associated with paint and varnish stripping operations. In addition, this high flow rate is achieved with only low pressure loss so that low pressure pumps with small motors can be used.

  • Patent number: 4754622
    Abstract: A water inlet device for an automatic clothes washer is provided which provides a flow of water against an interior surface of a wash basket and onto a clothes load within the basket through a wide range of inlet water pressures while preventing excessive splashing against the basket wall at high water pressures. The inlet device has a downwardly angled front wall which redirects the inlet water into the wash basket, and the wall has a varying downward angle along its length to provide the automatic pressure compensation. A central portion of the lip is angled downwardly toward the basket wall and the lateral edges are angled downwardly away from the basket wall such that at normal water pressures most of the inlet water is directed at the central portion, and thus toward the basket wall, and at higher pressures more water is directed toward the lateral edges which direct the excess water away from the basket wall and directly onto the clothes load.

  • Patent number: 4694792
    Abstract: A wet priming mechanism for small internal combustion engines. A priming line connects the main fuel line leading to the engine and the intake port to the cylinder. A manual bulb-type priming pump is located in the priming line and through operation of the pump, fuel is drawn from the main line and is discharged directly to the cylinder. Located at the discharge end of the priming line is a restrictor assembly which defines a small unobstructed orifice. The orifice is sized so that air will be freely discharged from the priming line by operation of the pump without resistance, but provides a substantial resistance to the flow of fuel. Through operation of the priming bulb, a measured amount of fuel can be injected into the engine to aid in starting.

  • Patent number: RE33448
    Abstract: A fluidic oscillator includes a chamber having a common inflow and outflow opening into which a jet is issued in a generally radial direction. After impinging upon the far chamber wall the jet is redirected to form a vortex on each side of the incoming jet. The vortices alternate in strength and position to direct outflow through the common opening along one side and then the other of the inflowing jet. A spray-forming output chamber is arranged to receive the pulsating outflows from the aforementioned or other fluid oscillator and establish an output vortex which is thereby alternately spun in opposite directions. An outlet opening from the output chamber issues fluid in a sweeping spray pattern determined by the vectorial sum of a first vector, tangential to the output vortex and a function of the spin velocity, and a second vector, directed radially from the vortex and determined by the static pressure in the chamber.
