Abstract: A drop-in oil filter having top and bottom caps having annular recesses on facingly disposed surfaces adjacent their outer periphery, a pleated, woven metal cylindrical filter element having an outer and an inner diameter, a first cylindrical wire cage over the outer diameter of the filter element, a second cylindrical wire cage within the inner diameter of the filter element, ends of the filter element and the first and second cylindrical wire cages being fastened into the annular recesses in the top and bottom caps, the bottom cap having a first opening there through concentric with and within inner diameters of the filter element and the first and second cylindrical wire cages, and a first elastic grommet within the first opening having a central opening for sealing on a tube within a drop-in filter housing.

Abstract: A reusable remote filter having a can-like body, a tubular woven metal mesh filter element fitting concentrically within the can-like body, and a cap having the first and second threaded openings therein, the cap being threadedly assembleable to the can-like body, the first threaded opening being in fluid communication with a first port at a right angle thereto, the first port flaring outwardly to be substantially of the same diameter as the inner diameter of the tubular woven metal mesh filter element when the reusable remote filter is assembled, the second threaded opening being in fluid communication with the periphery of the tubular woven metal mesh filter element around substantially the entire periphery of the tubular woven metal mesh filter element.

Abstract: A replacement filter for conventional throw-away spin-on oil filter cartridge on an internal combustion engine. The replacement filter uses a porous metallic filter element, preferably a woven stainless steel, pleated filter element, within a housing physically simulating the conventional throw-away spin-on oil filter cartridge. The housing is disassembleable, typically by unscrewing the top cap of the housing, for removal, cleaning and reuse of the filter element. This avoids the problems of cost and availability of replacement filters and of disposal of used filters. Various embodiments are disclosed.

Abstract: An integrated solar roof system, consisting of insulated roofing panels and collector panels, and method of producing same wherein the base assembly of the collector panel may be used with either an air or liquid absorber and is both an insulator and radiation shield as well as an integral structural part of the roof of the building on which it is mounted. The construction of the panels lends itself to mass production techniques and the efficient use of materials making the panels cost effective. The collector panels are also suitable for use as independently mounted units, functioning only as collectors and not as roofing members. Collector panels and insulated roofing panels, being identical in size and installation method, and said installation method being simple and quick, a suitable combination of panels may become a complete roof with minimal installation labor.
