Abstract: A device is disclosed which is adapted to be inserted in the threaded end of the sleeve of a pipe coupling to permit connection of piping thereto having either a convex-shaped end or a straight-tubular end by means of a correspondingly threaded nut which is capable of exerting an axially compressive force on the device. The device has a through bore, a portion of which is a socket substantially concave in shape for receiving the convex-shaped pipe end and a portion which is tubular in shape for receiving the straight tubular pipe end.

Abstract: A dispenser/diffuser member for filling storage containers for fluids, which is positioned between the inner end of the fill-pipe and the interior of the container to cause dispersion of the fluid flowing into the container from the fillpipe during a filling operation. The disperser member has therein a multiplicity of tortuous fluid passages, and may be used in a subterranean storage container, or in a mobile storage and transportation container (tank truck).

Abstract: A flow control apparatus for a brake master cylinder of a vehicle includes a valve chamber formed within a plug threadably secured to an outlet port of the master cylinder which is fluidically connected to the wheel cylinders of the vehicle, a flow control valve movably disposed within the valve chamber having projecting portions on one face of a flat portion thereof for providing a gap between the valve chamber wall and the valve in one end position of movement of the valve and a flow passage through the flat portion, a spring retainer secured within the inner end of the plug having a central opening for slidably receiving a central extension of the other face of the valve flat portion and a plurality of flow passages therethrough, and a compression spring between the other face of the valve portion and the spring retainer for normally maintaining the valve against the valve chamber wall with the projecting portions abutting thereagainst, whereby brake pedal depression and release alters the quantity of flui

Abstract: A controller, wherein the throttling range may be changed without affecting the calibration point, comprises a restrictive passage between an outer tube and an inner tube, the outer tube having one end connected to a source of pressure and the other end connected to atmosphere for establishing a linear pressure gradient along said restrictive passage, the inner tube having an output port at one end and an orifice for connecting the linear pressure gradient to the output port, and a controller for positioning the orifice along said pressure gradient.

Abstract: A static mold vent comprising a bore extending through a mold wall with a cylindrical inner portion opening at a cavity surface in the mold and a threaded outer portion opening at an exterior surface of the mold, a plug with a threaded outer portion engaged in the threaded portion of the bore and cylindrical inner portion projecting inwardly through the inner portion of the bore and cooperating therewith to define an air conducting annulus opening at said cavity surface, air bleed means in the plug communicating between the outer end thereof and the outer end of the annulus and tool engaging means engageable at the rear end of the plugs.

Abstract: An apparatus for regulating the flow rate of a fluid, comprising a casing having an annular or cone-shaped fluid passage, for radial flow (inwardly or outwardly) between an inlet and outlet which are spaced radially and form unobstructed flow paths to the whole of the fluid passage. The geometry of the fluid passage is defined for a compressible and incompressible fluid so that laminar flow is achieved in the fluid passage. The apparatus further provides a very rapid dynamic response, essentially free of hysteresis, and substantially no internal generation of fluid flow turbulence resulting in a minimum of noise and freedom from cavitation. In an adjustable configuration the apparatus provides a proportional fluid valving function. In a nonadjustable configuration the apparatus provides a laminar flow restriction.

Abstract: An air diverter valve for selectively diverting the output of an air pump in a vehicular emission control system from a combustion system to a diversion system, in response to each or all of a variety of system conditions including abrupt rise in intake manifold vacuum, continuing low intake manifold vacuum, continuing high intake manifold vacuum, or overtemperature conditions, and for controlling the duration of the diversion.

Abstract: A weight is attached to a conically shaped hollow member which rests on the top of a bed of particulate material in a tube, with the weight functioning to prevent fluidization of the material in the tube. The conical member is provided with elongated slots whereby fluid exiting from the bed flows into the interior of the hollow member, through the slots and into the tube outlet.

Abstract: A piston and slipper arrangement for a hydraulic pump or motor includes a tortuous fluid flow passage through the piston to a fluid pressure recess in the thrust face of the slipper at the opposite end of the piston. The fluid passage is formed by a plurality of spaced, cylindrical pockets interconnected by restricted flow channels which tangentially join the pockets.

Abstract: A multiple orifice assembly for increasing the flow resistance in a conduit for conducting fluid flow. The multiple orifice assembly comprises a plurality of orifices spacedly supported in the conduit and a diffuser which is supported intermediate adjacent orifices. The diffuser is spaced from the upstream orifice a distance less than that distance required for fluid issuing from the upstream orifice to fully expand back to the constraints of the conduit.

Abstract: An improved carbonated LIQUID dispenser has a passageway between the carbonated LIQUID and an outlet valve. A foam inhibiting portion of the passageway progressively decreases, then increases, then decreases, and finally increases again in flow area. Preferably the flow inhibiting portion of the passage comprises a chamber containing two spherical bodies which are fixed in the chamber and which are unequal in diameter.

Abstract: In an exhaust system for an internal combustion engine, wherein pollutants are removed from the exhaust gases by catalytic conversion, a pinwheel type of deflector positioned within the exhaust flow provides a radially-outwardly deflected swirl flow to the gases as they emanate from an exhaust pipe of one diameter into a canister of larger diameter for housing a catalytic converter. Such flow distribution results in improved catalytic conversion efficiencies obtainable by the converter and reduces its degradation rate inherent with time.

Abstract: The invention consists of provision of novel noise-silencing fluid-discharge devices which provide superior noise reduction. The devices comprise one or more flow-modifying elements which are made by rolling and compacting knitted metal wire mesh fabric. A preferred embodiment of the invention is an air discharge nozzle which is characterized by a high air discharge velocity while simultaneously effecting a sharp reduction in noise.

Abstract: Nested concentric sleeves or tubes subdivide flow of fluids through a fluid control valve into a myriad of streams between the valve inlet and outlet which flow through passages that create a high energy loss and pressure drop on the fluid to release the fluid at low pressures without generating noise, permitting cavitation or eroding equipment through which the fluid flows.

Abstract: A whirlpool jet for bathtubs having a water outlet extending through a circular opening in the bathtub wall and threadedly connected to a housing. The outlet has an annular radial flange abutting against the inside of the bathtub wall. The flange has a pair of diametrically spaced openings for use in rotating the water outlet in mounting the jet on a bathtub by using a circular wrench having a pair of pins which fit within the openings. The periphery of the wrench has knurling for manually rotating the wrench and a square central opening for receiving the square head of a driving tool. A jet outlet control which is rotatably mounted within the outlet has a concave area surrounding the inner end of a water passage in all rotational positions of the control, so that the water flow into the passage is constant. An extension for poured concrete installations is adapted to protrude beyond the edge of the concrete, the protruding portion being discardable.
