An inlet nozzle delivers a quantity of the fluid in the main fluid flow passage to the storage tank to be mixed with the chemical and an outlet nozzle return a quantity of the fluid mixed with the chemical from the storage tank to the main fluid flow passage. An adjustment dial having a plurality of orifices of varying diameter that are capable of being individually placed into relation with the inlet nozzle may be used to control the amount of fluid that enters the first inlet nozzle from the main fluid flow passage. Furthermore, an outlet nozzle trap in fluid communication with a vent port of the outlet nozzle may be placed in fluid communication with a fill control port of the inlet nozzle. The fill control port is used to direct fluid to the outlet nozzle trap to control venting of air from the storage tank to the main fluid flow passage via the vent port.

  • Publication number: 20030111627
    Abstract: A bleed valve assembly includes a valve poppet having a bleed portion and a base portion separated by a radially extending flange. The radially extending flange is located about the perimeter of the valve poppet to engage the valve seat on one side and receive a biasing member on the other. The flange engages the valve seat such that initial valve performance is similar to a disk valve, i.e., soft seating and very low leakage when closed. A plurality of openings extend through the bleed portion such that partial open operation of the bleed valve assembly is particularly tailored for a desired flow. As the valve poppet of the present invention moves off the valve seat, the initial gain is very low and then the gain increases steadily as more openings are exposed.

    Abstract: A pilot assembly for producing a pilot flame including a pilot which includes a housing and a multiple orifice member mounted to the housing. The housing includes a gas flow passageway providing gas fuel from a gas source to the pilot flame. The orifice member positions one orifice in the passageway for metering the rate of gas flowing through the passageway, and hence combusted by the pilot, according to the type of gas. The orifice member can be moved relative to the housing so that another orifice is in the passageway for metering the gas when the pilot receives a different type of gas.

  • Patent number: 6116278
    Abstract: A lockout valve comprises a body with an inlet passage and an outlet passage which define a longitudinally-extending flow path through the body. A flow interrupter device, or slide, is mounted for transverse movement within the body. The slide can be located in a closed position, whereby fluid is prevented from flowing from the inlet passage to the outlet passage, but fluid downstream of the lockout valve is allowed to vent to atmosphere; to an intermediate bleed position, whereby restricted fluid flow is allowed from the inlet passage to the outlet passage through a bleed aperture; and to a fully open position whereby fluid is allowed to flow substantially unimpeded through a flow aperture from the inlet passage to the outlet passage. A latch normally prevents the slide from moving from the bleed position to the open position while fluid pressure rises across the lockout valve. The latch can be manually manipulated to allow the slide to be moved to the open position.

  • Patent number: 6026854
    Abstract: A compressed gas regulator with integral flow meter is disclosed. The regulator includes pressure reducing section and a flow control section, as well as, a Bourdon tube gauge disposed within the protective surround of the regulator body to prevent physical damage to the gauge. The Bourdon tube is mounted on a gauge adapter that provides for rotation of the tube within the regulator body, yet maintaining a gas seal with the high pressure gas supply. The gauge adapter provides a means for fluidly communicating the high pressure level to the Bourdon tube, yet allowing rotation of the Bourdon tube for zeroing and calibration purposes. An indicator ring, also disposed within the regulator body, is mounted on the Bourdon tube so that the pressure level is readily ascertained by viewing the indicator ring through an aperture in the regulator body.

  • Patent number: 5856927
    Abstract: An automated routing tool for routing interconnections between circuit elements, standard cells and/or cell blocks of cell-based designs which incorporates the best features of both currently known gate array routing techniques with currently known cell-based routing techniques. The invention eliminates the disadvantages of permitting the detailed router to adjust the relative positions of the circuit elements, standard cells and/or cell blocks during the detailed routing process. The method employs a topology manager which iteratively compacts the circuit topology while at the same time optimizing the routing of the interconnections among the circuit elements, standard cells and/or cell blocks of the circuit design. The method employs bin-based global routing, which identifies expandable boundaries and which provides input to a compaction routine which expands or contracts the expandable areas in accordance with the result of the global routing process.

  • Patent number: 5716555
    Abstract: Disclosed is an adjustable apparatus for regulating the flow of fuel into a carburetor by use of a specially designed fuel metering rod. The hollow rod includes four different sets of holes along its sides at one end, each set separated from the adjacent sets by ninety degrees (90.degree.). The holes of each set are graduated from large to small, and each set covers a different range of hole sizes. The rod slides into a housing on the side of the carburetor, the holes regulating the amount of filtered fuel delivered to the carburetor. By sliding the rod, different sized holes on the rod line up with the exit opening in the housing to the carburetor. Sliding the rod also moves a linkage which causes the opening or closing of the air valves of the carburetor. The rod may be removed and rotated (either 90.degree., 180.degree. or 270.degree.) to allow a different set of holes to line up with the exit opening to the carburetor.

  • Patent number: 5653220
    Abstract: A burn rate control valve for gas fired heaters in the form of a 1/4 turn ball valve having two flow passages through the valve member in which one flow passage is for full gas flow and the other flow passage is smaller in diameter for low gas flow in order to provide a full burn rate or a low burn rate. The two passages are dimensioned and angularly related such that the larger or full burn rate passage essentially provides unrestricted flow when aligned with related ports or piping with the smaller or low burn rate passage being angularly related to the larger passage at an angle less than 90.degree. in order to maintain a flow passageway when the ball valve member is moved to a position with the larger passage perpendicular to the associated ports. This angular relation assures that the smaller flow passage will be opened before the larger flow passage closes too much in order that the burner will not cease to operate and not provide a lower burn rate than intended.
