Abstract: An apparatus and method for handling a fluid stream containing gas, liquid and solid particulate matter, which fluid stream issues from a conduit at a high velocity, such as from a geothermal well during the drilling, producing, testing or treating of the well. The fluid is passed first through an expansion conduit comprising a series of axially-aligned sections of increasing cross-sectional area and then through a vertical separator for particulate matter and noxious materials. Means is provided for injecting a treating material into either the conduit leading from the well to the expansion-conduit, the expansion conduit or the vertical separator.
Abstract: The water softening system hereof employs a treatment tank containing a mineral bed of ion-exchange resin granules, a brine tank, and a valve for periodically cycling water through the mineral bed for removing hardness and other undesirable factors therefrom, then passing a diluted brine solution through the bed in an opposite direction to its normal service flow to recondition and flush the bed. The control for the system includes electrically operated solenoid diaphragm valves, and a plunger valve responsive to water pressures, for controlling and regulating the flow of water and brine through the mineral bed. A venturi aspirator is incorporated in the plunger valve, whereby a saturated brine solution is drawn and with controlled dilution is caused to flow in a direction opposite to service flow through the mineral bed.
Abstract: A waste gas discharging device for use in an injection molding machine including a vacuum pump connected by way of a waste gas discharging unit to a vent hole in an injection molding machine, a branch path leading to a blower and connected between the vent hole and the waste gas discharging unit, the branch path being open and closed by a firstchange-over valve, and a second change-over valve disposed between the vacuum pump and the waste gas discharging unit, whereby waste gas from the waste gas discharging unit is discharged to atmosphere, without passing through the vacuum pump.
Abstract: A dual scavenging separator is provided which simultaneously scavenges out both clean air and particulates, such as dirt or water, from a contaminated flow medium such as air. The invention may be used in conjunction with aircraft environmental control systems to remove engine bleed air contaminants before the air enters occupied compartments or electronic units.
Abstract: A microporous filter having pleated filter cartridge is provided with inlet and bypass ports for establishing tangential flow across outside boundary of cartridge inlet side resulting in slow clogging operation.
Abstract: An autogenous or sinter bond between metallic filter media and other metal components of a filter assembly is produced by joining the parts through a diffusion bonding membrane. The membrane comprises a web of small diameter metal fibrils which will sinter bond to both the filter media and the other filter parts to form a physically strong and leak-free seal.
Abstract: An entrainment separator for separating liquids from gases and solids from gases, including a housing providing an inlet at one end and an outlet at the opposed end, an adjustable planar surface providing a face facing the inlet and an opposed face, an annular deflector beneath the planar surface attached to the housing and extending inward of the housing and positioned relative to the planar surface to provide an opening between the planar surface and annular deflector, means to adjust the position of the planar surface relative to the annular deflector, a tube attached to the opposed face of the planar surface and extending downward of the inlet, a funnel providing a downward extending spout positioned below the tube, means providing flow of liquid in the funnel past the tube and to the spout, and a gas outlet extending through the side of the housing.
Abstract: An apparatus for removing harmful substances from effluents has two chambers located symmetrically at opposite sides of an effluent channel. Each chamber contains two or more stacked trays which are each provided with a spiral flow path descending from a tray inlet to a tray outlet. All tray inlets are so located in the channel that substantially all effluent flowing in the channel is compelled to enter them and to travel by gravity through the respective tray. Air, an insert gas or a mixture of both is bubbled from below through the effluent flowing in the trays to expel and entrain the harmful substances. The treated effluent is then discharged back into the channel at locations downstream of its point of admission into the inlets.
Abstract: A vacuum receiver comprising a closed top vertical cylindrical tank with a central vacuum takeoff at the top, a tangential downwardly inclined feed conduit in the sidewall, an inverted conical bottom section with anti-swirl baffles therein, and a barometric leg extending downwardly from the apex of the bottom to termination in submergence in a lower seal tank. A conduit is provided to recycle a portion of discharge liquor from the seal tank to the top of the barometric leg. The slope of the conical bottom does not exceed about 40.degree. from the vertical wall and inclination of the inlet conduit is about 15.degree. from horizontal. The barometric leg length and diameter as well as the liquor recycle rate are selected to optimize final liquor discharge rate at prevailing vacuum and foam conditions.
Abstract: A system is provided for continuously removing contaminants from a fluid stream on a high volume basis, such system being adapted particularly for use with contaminated lubricating oil found in industrial heavy equipment such as drop forges which requires large volumes of lubricating oil for effective, continuous operation.
Abstract: A filter system includes a tank with a removable cover at one end and a filter basket and liner therefor insertable into the tank to divide it into unfiltered liquid and filtered liquid zones. Inlet and outlet openings are disposed at the open and remaining end, respectively, of the tank with the inlet opening being in the side wall of the tank, near such open end, so as not to interfere with opening and closing of the cover. Inner and outer annuli are fixed to the tank side wall and face radially into the tank, with the inlet opening interposed axially therebetween. A spacer insertable into the tank comprises an annular inner disk pressable toward the inner annulus for gripping therebetween an inner resilient seal which in turn engages the adjacent edges of the filter basket and filter liner to prevent leakage therearound between the unfiltered and filtered liquid zones.
Abstract: Drilling mud degasification apparatus comprises a degassing chamber located below the level of gas-laden mud in a tank. A propeller pump causes the mud in the tank to flow through a plurality of restricted orifices in the degassing chamber at a rate faster than that at which the mud would normally flow through such orifices to liberate the gas bubbles therefrom. A cyclone separator finally separates the so-liberated gas from the mud.
