  • Publication number: 20150078921
    Abstract: A device for dispensing an air treatment chemical includes a housing having an inlet for permitting air to enter into an interior space of the housing and an outlet for permitting air mixed with air treatment chemical to exit the interior space of the housing. A substrate positioned within the housing bears the air treatment chemical. A power supply mounted within the housing powers a motor mounted within the housing. The motor is connected to an impeller mounted within the housing. The impeller moves air from the inlet adjacent the substrate to mix the air treatment chemical into the moving air and deliver the mixture of air and air treatment chemical through the outlet to outside of the housing. The housing includes a transitional body defining a convergent-divergent channel for compressing the mixture at the converging section and expanding the mixture at the diverging section.

  • Publication number: 20120275932
    Abstract: A dispensing device includes a housing, a fan, and an annular reservoir. A compound is disposed within the reservoir. The dispensing device further includes a permeable substrate in communication with the annular reservoir for releasing the compound in a first passive state. The compound is released from the permeable substrate according to a uniform diffusion profile. Rotation of the fan causes air to pass over the permeable substrate to release the compound in a second active state.

  • Patent number: 7207781
    Abstract: A pressure exchange device is provided that utilizes a rotor assembly inside a housing to transfer the pressure of a fluid from one high pressure fluid to another low pressure fluid. The housing may comprise a pressurized fluid contained therein to provide a sealing force to reduce fluid leakage between the spinning rotors and the housing. The sealing force and wear characteristics may be controlled to reduce leakage and wear of the pressure exchange device. The rotor assembly may be driven in either direction and the high pressure ports may be switched with the low pressure ports if desired.

  • Patent number: 6241479
    Abstract: In a method of compressing a gas, a compression which is simple to realize is achieved in that, in a first step, a foam (21) is formed from the gas and a liquid, in which foam (21) the sonic velocity is markedly lower than in the gas and in the liquid taken by themselves, in that, in a second step, the foam is directed at supersonic velocity through a nozzle (19, 20) and the gas located in the foam is thereby compressed, and in that, in a third step, the compressed gas and the liquid are separated from one another behind the nozzle (19, 20).

  • Patent number: 6146111
    Abstract: A water pump allows adjustment of the drive belt by rotating a portion of the water pump housing. The water pump eliminates the need for additional drive-belt tensioning parts, therefore simplifying maintenance procedures. The pump housing has a support member mounted thereto, with a pump shaft extending therethrough. The support member flange includes eccentrically-formed mounting grooves. The support member is rotated by the loosening of adjustment screws securing it in place. By rotating the support member, the location of the pump shaft is re-oriented and the tension of the drive belt adjusted.

  • Patent number: 5755288
    Abstract: A gas compressor is employed downhole in a well for pressurizing formation gas. The gas compressor is driven by a downhole electrical motor. The downhole assembly also includes a pump. The pump might be located below the motor and driven by the same motor. In that event, the pump pumps liquid being produced by the formation downward to a liquid disposal formation. Also, the pump may pump the liquid to the surface, with the gas being delivered into a repressurizing zone.

  • Patent number: 4917577
    Abstract: A centrifugal oxygenator pump includes a bottom inlet into an impeller chamber, the bottom inlet having a venturi gas inlet for mixing gas with the in flowing liquid. The impeller chamber is of a frusto-conical shape within which is rotatably mounted a similarly shaped mismatched impeller, the impeller driving the liquid and gas mixture toward a toroidal outlet chamber and through an outlet to an outlet nozzle. The motor drives the impeller to attain a high specific speed so that an increased capacity and larger size oxygenator is provided with maximum efficiency and effectiveness.

  • Patent number: 4764311
    Abstract: The present invention provides a process and apparatus for mixing gaseous mixtures into sea-water pumped from an aquarium through the contact tube of a protein skimmer. The invention forms air bubbles of a specific uniform diameter so as to obtain an optimum skimming. The apparatus has a centrifugal pump closed about the periphery of the vanes at the suction side. A suction port at the axial part of the impeller forms water intake ports which surround an internal gas injection connection projecting into an axial water suction connection of a central disk fixed within the suction port of the impeller. The height of the water column over the suction point can, within limits, be taken into account by different gas and water suction cross-sections, adjustment of the gas injection connection relative to the water suction connection, and different sizes of the impeller.

  • Patent number: 4351514
    Abstract: An improved molten metal pump and gas injection apparatus comprising a submersible pump housing 10 enclosing a rotatable impeller 30, an impeller drive 12 supported above the housing and an elongate drive shaft 16 operatively connected to the impeller. Rotation of the drive shaft effects fluid flow between a pump inlet 35 and a pump outlet 44 both being at least partially defined by the impeller housing. A gas injection conduit 54 extends downwardly from a drive motor support platform 20 and includes an output end 54a that terminates near the pump inlet and which is received by a gas inlet collar 58 that defines a venturi 60, coaxial with the axis of the pump inlet. A passage 62 formed in the collar communicates the end of the gas injection conduit with the throat of the venturi so that the gas is injected into the incoming molten metal in an area of low pressure, thereby reducing the gas pressure needed to effect injection.
