Abstract: A control valve assembly for use in a reverse osmosis system in which a tank and a pliable barrier are used to define a reservoir having separate confined spaces for purified water and reject water. The barrier when not deformed occupies only a portion of the interior of the tank, and requires a minimum of material to define. The uppermost part of the tank supports a single valve that has a pressurized feed water inlet and outlet, and a movable portion that extends into the interior of the upper interior portion of the tank. Upward movement of the movable portion throttles the rate of flow of pressurized feed water between the inlet and outlet. The barrier in addition of sub-dividing the interior of the reservoir into separate confined spaces of variable volume also serves to physically contact the movable portion and move it upwardly as the first confined space moves towards a last stage in approaching a filled condition to throttle the flow of pressurized feed water through the valve.

The oil entrained by the surface of the plates (3) on emersion from the liquid level is stripped by means of strippers (4) and supplied to a collecting launder (5).

Abstract: Particulates which are less than and greater than a predetermined size and are entrained in a fluid are separated according to their respective sizes by passing the fluid and entrained particulates through a porous, crossflow separator element while continuously vibrating the separator element to prevent buildup of particulates on the upstream side of the separator element.

Abstract: The present invention provides an apparatus and method for the separation of solids entrained in fluid streams. The apparatus consists of a pipecross-like chamber which is divided into two regions by a perforated deflector/separator plate angularly disposed within the chamber. A shear jet is disposed perpendicular to the flow path and higher pressure fluid is thereby injected into the chamber to deflect and separate entrained solids. In preferred embodiments the apparatus and method are used to protect a centrifugal pump impeller from damage by the solids. While conventional pipe joints and parts can be used, an alternate embodiment provides removable side plates and a removable deflector/separator plate for ease of installation and maintenance.

Abstract: The apparatus for continuously separating liquid phases of different density consists of a separating basin (1) within which are arranged partition walls (5) for being lifted and lowered and for being moved one in direction to the other or for being swivelled. Swivelling of the partition walls (5) is effected about an eccentrically arranged axis (7) such that during the swivelling movement the partition walls (5) are simultaneously lifted or lowered. The partition walls (5) can be driven by push rods (8) and thus be swivelled in the contrary sense. When swivelling the partition walls (5) in one direction, the liquid level is lifted in the chamber defined between the partition walls and is lowered in the adjacent chamber, noting that the portion having the lower specific gravity flows over the upper edge, assuming a lower level, of the one partition wall in one direction (11) and that the proportion having the higher specific gravity flows in direction of the arrow (12), i.e.

The actuator (20) moves the receiver (19) along rails (17,18) between the two positions.

Abstract: A filter for hot melt adhesive is carried within a passageway in a manifold and is rotatable therein between a filtering position in which hot melt adhesive is directed to the inner core of the filter at one end thereof, and a backflushing position in which hot melt adhesive is directed onto the outside surface of the filter at the opposite end thereof. In the filtering position, the hot melt adhesive flows from the inner core outwardly through a filter screen into the main passageway for collection and discharge from one end of the manifold. In the backflushing position the adhesive flow is directed from the outside surface of the filter in the reverse direction through the filter screen to dislodge filtered impurities therefrom, and then the impurities are carried out a drain at the opposite end of the manifold.

Abstract: A separating device for separating a pair of immiscible components from a fluid mixture, such as separating water from a diesel fuel oil/water mixture, includes a housing and a filter cartridge mounted on the housing such that the filter cartridge is oriented substantially horizontally. The housing includes an inlet fitting, an outlet fitting, and a sump for receiving the fluid component separated from the mixture. Because of the orientation of the housing, the coalesced water or heavier component of the fluid mixture tends to collect in the lower portion of the filter cartridge and drains into the sump, where it may be drained periodically. The lighter component or fuel oil is communicated to the outlet port or fitting.

Abstract: The ground-water sampler collects a time-averaged or composite sample of the ground water. The sampling system was designed to be self-contained and all sources of power being contained within the well casing. The sampler collects the sample on a sorptive media and the media analyzed by a laboratory. The sampling system prevents the exchange of gases between the ground water and the atmosphere. The exchange is prevented by a well packer which is designed to be placed in well casings of 2 inches or greater. The well packer can be easily and economically placed into the well casing with the use of a packer tool. The sampler is inserted into the well packer and once inserted a one-way check valve opens to the aquifer allowing the water to be sampled. After the sampling episode, the sampler is removed from the well packer and the one-way check valve closes. The media is then analyzed in a laboratory.

Abstract: A plurality of different liquid solutions are connected to an input of a pump system having at least two displacement chambers and in a manner to control the proportions of each constituent that are taken into each chamber during its intake stroke. The outputs of the chambers are connected to a common liquid output. The chambers are driven by independently controllable motors so that the discharge stroke may be chosen to have some parameters, such as speed profile and duration, that are different than during the intake stroke. As a result, both chambers may simultaneously discharge liquid through the common output, if desired. The proportion of constituents may be made different each time one of the chambers is filled, so the simultaneous discharge of the chambers allows a gradual, carefully controlled change from the mixture of one chamber to that of the other.
