Abstract: The present disclosure sets forth an adapter for installation on an automobile engine in lieu of a disposable cartridge filter. The adapter includes inlet and outlet fittings. The inlet and outlet fittings connect through a pair of flexible hoses to a raised filter housing installed at an elevated location in the engine compartment. The system also includes an oil reservoir which accumulates oil under pressure where the oil under pressure is stored until engine starting. This enhances lubrication within the engine at the upper portions thereof to avoid dry starting which occurs when the oil otherwise settles to the bottom of the engine. The reservoir in conjunction with the filter housing operates with selected valves and checkvalves so a hydrostatic head of oil pressure is achieved even when the engine is not operating.

Abstract: A downhole running tool for positioning and locking tool support mandrels within landing nipples of the production tubing string of a well. A housing is provided which forms an internal receptacle receiving upper and lower core sections forming an elongated core which is telescopically movable to collapsed and extended positions defined by spaced stops formed by the housing. A portion of the core extends from the housing for connection with a tool support mandrel. A collet type releasable retainer secures locking lugs of the housing in a substantially fixed position within the internal receptacle and is movable to a lug release position upon contact with the landing nipple during upward movement of the downhole running tool to thus permit spring urged movement of the core to force the mandrel from its retracted position to its locating position.
