An enclosed filter is disclosed herein having an elongated container or housing composed of transparent material incorporating a plurality of adjacent filtering chambers separated by a mesh partition or grid. Filter material especially suited for removing chloramine occupies each chamber and pump apparatus is employed for drawing water through an open grid end of the housing through the chambers for existing via a discharge port in the pump apparatus.

A reusable liquid filter assembly having a housing having two internally threaded ends and two externally threaded removable end walls. Sealing O-rings are provided on the end walls to bear and seal against bevelled zones on the housing ends. A filter subassembly is positioned in the housing and centered therein by the end walls. A port is provided in one end wall for sampling the filtered liquid. The liquid filter is readily disassembled for cleaning and replacement of all of its components.

A fluid flow baffle for fuel processors is described particularly adapted for fuel processors of the type having closely adjacent inlet and outlet flow ports. The fluid flow baffle separates incoming fuel from treated fuel to prevent contamination of the fuel processor's filter device by heavy contaminants and water entrained within the incoming fuel. The baffle further improves the thermal efficiency of the fuel processor device by acting as an insulating barrier and by providing optimal flow patterns for the incoming and heated fuel. Several embodiments of the fuel flow baffle are described, one adapted for one type of fuel processor in which fuel flows through the filter element in a radially inward direction. Another embodiment relates to a baffle intended for use in another type of fuel processor having a fuel flow direction in a radially outward direction.

A pressure vessel of the type used in domestic water purifying systems for the filtering of potable water, wherein an uncompromised, spherically ended cylindrical pressure vessel housing is provided which is manufactured of a very strong high quality resin and comprises two detachable major sections sealed with an O-ring and secured together through provision of a threaded annular collar; quick connect type plumbing fitments are provided at an inlet port and an outlet port of the pressure vessel housing requiring no tools to facilitate the removal and attachment thereof; a decorative plastic shell manufactured of less expensive resin is provided to encase the pressure vessel to provide structural stability and which can be fabricated to also provide aesthetic flexibility with regard to shape and color and may also provide a compartment for incorporating an electric flow meter.

A fuel processor device is described which is particularly adapted for replacing existing fuel filters of diesel powered machines and fuel consuming devices. The fuel processor designs described have inlet and outlet passages within their upper surface and include a lower plate assembly which provides a mounting location for various elements such as water sensors, drain valves, temperature sensors and heaters which are provided in accordance with the user's needs. The lower plate assembly may be mounted directly to a housing by a through bolt or matching threads or may be made integral with the fuel processor housing. The fuel processor device may include an integral throwaway filter element or the element may be integrated with the fuel processor housing. Various control means may be employed in connection with the fuel processor disclosed wherein the automatic drain water or other accumulated impurities from the lower portion of the fuel processor housing. Additionally, heaters and heater control elements can be installed to aid in fuel water separation and prevent fuel waxing. Since these fuel processors are adapted to be mounted to existing mounting provisions, the requirement of a remotely mounted fuel processor is avoided and therefore the provision of additional fuel lines and fittings is eliminated.
