Abstract: A first pump can withdraw waste fluid from an oil pan reservoir and optionally, can be used to introduce flushing fluid through the oil filter and internal oil lubrication distribution passage system, to recirculate the flushing fluid within the internal oil lubrication distribution passage system, to withdraw the waste flushing fluid from the oil pan reservoir for disposal and storage in an external storage receptacle. An air purge connection is provided for evacuating fluid retained within the oil filter element and any fluid remaining in the internal oil lubrication distribution passage system into the oil pan reservoir prior to withdrawal of the fluid by the first pump. A second pump is provided for supplying fresh motor oil from an external storage receptacle through the oil filter and the internal oil lubrication distribution passage system.

Abstract: A process and apparatus for changing the oil in an engine and/or flushing and/or cleaning the moveable parts in the engine. The device includes an oil filter adapter adapted to be positioned in the oil filter boss, a remote oil filter mounting boss and inlet and outlet hoses connecting the two. The device is attached to the engine. Suitable pump-out and fill lines are connected to the device and can be releasably attached to an external pump device. When the device is employed to change oil, the external pump device is connected, and spent oil removed from the oil pan under suction force through the pump-out line. A measured amount of fresh oil is then introduced through pump-out line alone or through the pump-out line and the fill line and internal lube oil distribution system. Once accomplished, the external pump device can be uncoupled.

Abstract: Quick connect coupling adapters for facilitating simplified rapid oil change in an associated internal combustion engine, including a drain opening adapter having an integral body with a central throughbore and a branch throughbore angularly oriented thereto. The adapter includes appropriate means for attaching an end of the branch throughbore to the drain plug opening and means for sealingly attaching the drain plug to one end of the central throughbore. An oil conveying hose is attached to the other end of the central throughbore. The oil conveying hose includes a quick connect coupling releasably attachable to an external pump device. An additional oil fill adapter is positionable in a suitable engine opening such as the dipstick tube or oil fill opening in the valve cover. The oil fill adapter includes a central oil conveying body having an inlet and an outlet means for attaching the outlet in the engine opening, and a fill hose attached to the inlet.

Abstract: A process and apparatus for changing the oil in an engine and/or flushing and scrub cleaning the moveable components in the engine utilizing the internal lube oil distribution system of the engine. The device includes an oil filter adapter positioned in the oil filter boss, a remote oil filter mounting boss and inlet and outlet hoses connecting the two. The device is mounted in the engine compartment. Suitable pump-out and fill lines are connected to the device and can be releasably attached to an external pump device. When the device is employed to change oil, the external pump device is connected, a brief surge of purge gas is introduced to remove spent oil remaining in the oil filter and internal lube oil passages and spent oil is removed from the oil pan through the pump-out line. A measured amount of fresh oil is then introduced through the fill line and the internal lube oil distribution system. Once accomplished, the external pump device is uncoupled.

Abstract: A water entrapment device is provided, the device comprising a housing having an opening at the front and back, and an entrapment portion disposed within the housing. The entrapment portion comprises at least one screen covering the front opening, at least one entrapment member behind the screen, and an absorbent member behind the entrapment member. The device further comprises a water collecting surface and a drain.

Abstract: A process, apparatus and alloy for net forming intricate metallic shapes. A fixed die (30) is mounted in a forging press (20). The die (30) has a cavity (45) at least the proximal end (62) of which is open to receive a ram (55). The cavity (45) is contoured to the shape of the finished article to be forged therein, and a metallic slug (50) is receivable within the cavity (45). The ram (55) is driven into the proximal end (62) of the cavity (45) against the proximal end (63) of the slug (50) under selected pressure and temperature and for a selected period of time. The slug (55) is thereby forged into close conformity with the contours of the cavity (45), the formation of the slug (50) being accomplished first at the distal end (64) of the slug and thereafter being progressively initiated and completed toward and proximal end (63) thereof.

Abstract: Reusable self-locking fasteners, and methods of metal fasteners wherein the self-locking characteristic is derived from a patch comprising a metal or metal alloy selectively applied to the threaded surface of the metal fastener in a spraying operation. The metallic patch may comprise a single metal or metal alloy or a composite of metals or metal alloys selectively bonded to the threaded surface of the metal fastener by single or multiple molten spraying operations respectively.
