  • Engine primer dispenser
    Patent number: 6012422
    Abstract: A single-use aerosol can having an outlet and no inlet and containing a lubricant under pressure that is used to prime an engine prior to start-up. The contents of the canister are pressurized with a substantially non-flammable propellant and are released from the single outlet atop the aerosol can through a valve that is interposed between the outlet and the interior of the canister. The valve may be manually depressed to cause the lubricant to be released. The lubricant is transported directly from the outlet of the canister to the interior of the engine through a hose having a first passageway, a first end, and a second end. The hose is sealingly connected to the canister on the first end and the oil passageway of the engine on the second end. A threaded fitting having a second passageway may be used to attach the second end of the hose to the oil passageway, thereby creating communication between the first and second passageways.

  • Apparatus for flushing an automatic transmission cooling system
    Patent number: 5392796
    Abstract: A method and apparatus for flushing an automatic transmission cooling system. A sealed pressurized canister having an outlet and no inlet and a biodegradable soap solution thereinside is coupled to the cooling system, and a valve releases the soap within the canister through the cooling system. A tube within the canister extends from the canister's outlet into the soap solution, and after the soap is expelled from the canister, the canister is inverted and pressurized air from the canister purges the soap solution from the cooling system. A bag may be provided to catch the waste soap solution emerging from the cooling system.
