Title: Fuel filter and pressure regulator system apparatus
Inventor: BRANDT TIMOTHY B
IPC: F02M37/50
Filed: 1991-12-13
Abstract: A combination fuel pressure regulator and fuel filter apparatus for vehicle fuel systems has a fuel supply tank with a fuel pump therein for pumping fuel to a fuel supply rail having fuel injectors attached thereto.  A fuel filter is operably disposed between an inlet supply tube and a fluid outlet tube for filtering impurities from fuel passing therethrough.  A valve in fluid communication with the inlet supply tube is provided with a regulator for causing flow to be short circuited back into the fuel supply tank when the pressure in the fluid outlet exceeds a predetermined level.  The valve is biased to a closed position and will remain closed as long as the pressure on the clean side of the filter is below the predetermined pressure whereby all of the fuel in the inlet supply tube will pass through the filter.

Title: Electronic circuit breaker with protection against sputtering arc faults and ground faults
Inventor: MACKENZIE RAYMOND W
IPC: H02H1/06
Filed: 1992-09-25
Abstract: A circuit breaker bandwidth limits a sensed rate of change of current, di/dt, in the neutral conductor of a protected electrical system and fullwave rectifies the. bandwidth limited di/dt signal for comparison with an instantaneous trip reference signal. The bandwidth is selected to provide a selected relative sensitivity of the instantaneous trip to sinusoidal currents associated with overcurrent faults and step currents associated with sputtering arc faults. The rectified bandwidth limited di/dt signal is also filtered and delayed for comparison with a delayed trip reference signal. The time constant for the filter is selected to provide a selected relative sensitivity of the delayed trip to overcurrent faults and sputtering arc faults. A low mu sensing coil used to generate the di/dt signal can also serve as the neutral current sensing coil of a dormant oscillator ground fault protection system.
