Abstract: A filter apparatus is disclosed for separating fluids of different densities. The apparatus has a relatively small housing size such that it is particularly suited for installation in passenger vehicles. The construction of the subject filter is intended to eliminate sealing problems found in the prior art as well as to permit the utilization of a filter having increased capacity.

Abstract: A captive air system for a water well. A submersible type pump is located downhole in a wellbore for pumping water from an aquifer to the surface of the earth. A special storage tank is buried below the surface of the earth. The tank has a relatively short vertical leg connected to a relatively long lateral leg which slopes downwardly away from the vertical leg. A water supply conduit is located at the lower end of the lateral leg. The pump outlet is connected to the interior of the vertical leg. A blowdown pipe is connected to the bottom of the vertical leg. The edge portions of the tank which join together the vertical and lateral legs serve as a dam so that as the liquid level in the storage tank is lowered, debris always remain in the bottom of the vertical leg while clean fresh water is delivered by the lateral leg.

Abstract: A tractor trailer chassis compactly mounts a waste oil cleaning apparatus of hydraulically connected, primary components. A diesel fuel burner fired heater of vertical cylindrical form mounts at one end of the chassis. A blower feeds a large volume of air under pressure to a cylindrical fire box where a fuel air mixture is ignited and fed tangentially into the base of the central chamber within the heater where the products of combustion follow a helical path within the central heat exchange chamber. Waste oil is fed counterflow along a second helical path through an annular chamber separated by a cylindrical metal heat conductive wall from the chamber bearing the products of combustion. Heated waste oil is fed from the heater to a vibrating table type solids separator or shaker mounted at the opposite end of the trailer chassis from the heater where solids are separated from the heated waste oil.

Abstract: A fuel filter connectable in-line to a fuel system of an internal combustion engine has first and second separation means. The first separation means includes a reservoir in which fuel and larger contaminates settle and can be drained. The second separation means includes a baffle and screen mounted within a main body generally transverse to the fuel flow. A cap is selectively connectable to the main body to hold the screen in a set position and to further provide a passageway from the interior of the fuel filter to an outlet to the fuel system.

Abstract: In an automobile fuel system and particularly for a diesel powered vehicle, it is desirable to provide a water separator to prevent passage of water to the engine and particularly the fuel induction components. It is also desirable to provide ejection means for the separated water which may include a provision to prevent the ejected water from falling to the ground.

Abstract: An apparatus for providing permanent decantation and separation of solvents miscible or nonmiscible in water, which are nonconductive and are absorbed by activated carbon. Water containing the solvent is passed through a decanter separator for separating nonmiscible solvent from the water solution. After flowing through the decanter separator, the solvent saturated water is gravity fed to a filter element of microscopic porosity for absorbing solvent dissolved in the water. The water is then passed through a detection cell which is connected downstream of the filter element. The detection cell includes a solvent vapor detection head connected to an electronic circuit controlling alarms. Air is bubbled through the water and the detection cell to accelerate evaporation of the solvent dissolved in the water. If any solvent is present in the air, the detection head activates visual and sound alarms.

Abstract: The present invention relates to a multi-stage, single vessel, purification system for removing solid particles from liquids.Within the central portion of the vessel is a deceleration chamber having flow control means. About and substantially coextensive with the deceleration chamber is a filtering chamber. Depending well into the filtering chamber are a plurality of septums preferably coated with filter aid. Below the deceleration and filtering chambers is a settling chamber, and beneath the vessel is an expulsion device.A contaminated liquid is fed into the deceleration chamber and decelerated. In this chamber the lighter solid particles rise to the top of the liquid where they are removed, while the heavier density particles settle downwardly. As the liquid moves downwardly from the deceleration chamber it essentially displaces liquid in the settling chamber upwardly into the filtering chamber. In so doing the change of direction of liquid movement also causes the heavier particles to settle downwardly.

Abstract: A trapping device for trapping foreign liquids having a specific gravity greater than that of a supply liquid comprises a settling chamber defined primarily by a tubular side wall and two end pieces and inlet and outlet chambers in the settling chamber and adjacent to an upper one of the end pieces. An inlet and an outlet lead to and from the inlet and outlet chambers, which are separated by an imperforate wall. The imperforate wall has a pair of wing means diverging radially outwardly. Foraminous wall means are arranged so that fluid passing through the chambers from the inlet to the outlet passes through the foraminous wall means.

Abstract: A fluid valve apparatus particularly for pneumatic service (air or other gases) in a filter/separator for opening and closing a valve in response to the level of liquid in a container. The apparatus includes a valve having a magnetically attractable portion and a float having a magnet therein adjacent but physically separated from the valve for opening and closing the valve magnetically in response to changes in the liquid level within the container. In the preferred embodiment, the valve apparatus is used with a filter/separator in an air pressure supply line to automatically dump water and other liquids condensed from the air supply and collected in the filter reservoir.

Abstract: A marine sewage disposal device connectable to a toilet and flushed by water, in which the sewage is macerated to small particle size, subjected to heat and electric current to destroy coliform bacteria, and subsequently filtered to separate liquids from solids prior to being discharged. Power requirements are relatively low, in the order of 2 to 5 amperes at 110 volts A.C., or less, thereby permitting the device to be used on relatively small craft having minimal generating equipment, such as a standard generator arranged to bypass the usual voltage regulator.

Abstract: An improved self-contained apparatus for the separation of low density fluids from higher density insoluable fluids or particles or both in which initial separation, coalescing and filtration steps are carried out substantially in series and in that order, is disclosed. Specific embodiments of such apparatus for use in oil-water separation are described and specific structures and devices for use in such apparatus are disclosed.
