Abstract: A pump drip control system for attachment to a pump assembly to prevent premature replacement of the pump. The control system includes a pump housing having a leakage collection chamber and a drip cap engaged with a second end of the leakage collection chamber. The drip cap includes a circumferential channel defining a flow path to a gathering chamber. The pump drip control system further includes a slinger assembly located within the leakage collection chamber, and wherein, in operation, the slinger assembly directs liquid leakage from the impeller shaft to the drip cap and the circumferential channel within the drip cap which directs the liquid along the circumferential flow path and into the gathering chamber. The gathering chamber can hold a predetermined amount of liquid until the liquid evaporates and includes a liquid exit port for draining excessive liquid out of the pump housing to another location.

Abstract: A rolamite sensor for use in sensing deceleration of a vehicle includes two separate electrical circuits for actuating two occupant restraints such as air bags. The sensor has a molded plastic base mounted on a metal chassis and a metal cover welded to the chassis to sealingly enclose the base. One surface of the base acts as a guide surface for a roller. A pair of thin metal bands are wrapped around the roller. Each band is fixed at one end to the base and at the other end to a J-shaped tensioner underneath the base. The roller is rollable on the guide surface under an applied force to cause the band to engage firing contacts to complete the electrical circuits. An optical electromagnet may be fixed to the chassis without increasing the overall size of the sensor. The electromagnet is selectively operable to attract the roller to test the sensor by completing the electrical circuits. The electromagnet includes a ferromagnetic core and a coil wound directly on the core.
