Abstract: An oil filter removal tool having a base and axially compressible bellows attached at a liquid-tight joint to the base that telescopes over an oil filter being removed defining a container that collects excess oil during filter removal. Base has a filter engaging recess with a fluid passage enabling oil collected during removal to flow into a reservoir between the filter and base. Another reservoir formed between filter and bellows holds additional oil. Joint is formed by a seating arrangement having a configuration that also strengthens the tool. Bellows can compress to seal against pan ensuring oil in oil pan and filter that spills during filter removal remains within tool. After removal, bellows can return to its uncompressed length providing a container sidewall extending outwardly beyond filter enabling collected oil to be transported and dumped into a container.

Abstract: A powder coating gun with an internal fan and a quick-change powder cartridge. Pressurized air generated by the fan entrains the powder coating material from the powder cartridge and the entrained powder coating material is charged in the ionizing field created by an emitter. The replaceable cartridge contains an inlet line and an outlet line oriented in a manner that allows the powder gun to be positioned in different angles and orientations with minimal risk of a powder spill from the powder coating gun. The powder cartridge contains a lid for supporting an inlet line and a body part constructed of clear or translucent material that allows the user to easily view the color of the powder. An electric power supply is used to power the fan and the emitter. A trigger is present in the handle of the powder coating gun and both controls the speed of the fan and enables the charge to the emitter.
