Abstract: A fluid level sensor comprising a novel electronic circuit which monitors change in the fluid level in a reservoir through a conductive probe disposed therein. The probe and a capacitor are electrically connected in a circuit which is intermittently energized to create an electrical transient therein. The transient is monitored, and a warning is given when the transient indicates that the probe is not in contact with the fluid in the reservoir. Two species of the invention are disclosed as applied to a vehicle hydraulic brake system having a dual reservoir type master brake cylinder with a probe for each reservoir. In one species, only a single capacitor is required since the electronic circuit electrically connects each probe with the capacitor sequentially by means of time multiplexing.

Abstract: Windshield wiper coupling, including a tubular member having a threaded portion extending through a hole in an automotive vehicle structural part. A rotatable member extends through the tubular member and is connected at opposite ends to the wiper and to an actuating assembly. A washer surrounds a threaded portion of the tubular member and is and has a deformable finger in a slot in the threaded portion. A nut deforms the deformable portion when tightened on the threaded portion.

Abstract: Both visible and audible warning signals are provided for the purpose of promoting safety belt usage by the occupants of a vehicle. The warning signals are given for a limited time period subsequent to actuation of the usual ignition switch from the "off" position to either "start" or "run" position. If the driver fastens his safety belt prior to the expiration of the aforesaid time period, the audible alarm is terminated. Accuracy in the timing function is attained via an electronic control circuit.

Abstract: Fixed seal means partition a disc type rotary regenerator for an automotive gas turbine engine into an inlet air heating section for conducting cool high pressure inlet air therethrough in one axial direction and an exhaust cooling section for conducting hot low pressure exhaust gas therethrough in the opposite axial direction. The seal means comprises a non-rotatable rubbing seal having an inner surface in sliding sealing engagement with an axial end surface of the regenerator and also comprises a channel shaped non-rotatable static seal having one channel side in sliding sealing engagement with a movement limiting stop fixed with respect to an outer surface of the rubbing seal at the low pressure side thereof and having a second channel side in sliding sealing engagement with a fixed housing portion of the engine.

Abstract: A camming surface on the inner peripheral edge of the transom opening limits steering angle of the I/O power leg as it is tilted up. Full steering is permitted at lower tilt positions and limited steering is permitted at raised positions. This arrangement makes the unit more adaptable to various size transoms, affords a neater appearance and reduces weight and cost.

Abstract: A control system for an automatic transmission of the type having an input shaft assembly, an output shaft assembly, a plurality of power transmitting gear assemblies connecting the input shaft assembly and output shaft assembly and adapted to be coupled to provide various ratios between input and output shaft assembly rotation, engaging devices for effecting changes in the ratios provided by the power transmitting gear assemblies, and servos for operating the engaging devices. Pressure regulating devices are provided for controlling the application of pressurized fluid to the servo means, and control apparatus is provided which is responsive to the rate of change of rotational speed, i.e., acceleration, of at least one of the rotatable components of the assemblies to control the output torque of the transmission during a shift from one ratio to another.

Abstract: The compressor motor of an air conditioning unit is operatively coupled to a A.C. line through a solid state electronic switch. Triggering signals for the switch are supplied from an oscillator circuit which is D.C. isolated from the switch, the trigger signals being coupled via transformer coupling. The oscillator is in turn thermostatically controlled in accordance with the cooling demand. The oscillator is also interlocked via a photocoupling device with an electronic timer circuit and with an undervoltage sensing circuit. The timer imposes a mandatory minimum delay between successive energizations of the compressor motor thereby permitting time for pressures in the refrigeration circuit to subside. The undervoltage sensing circuit is responsive to an electrical brownout condition for shutting down the motor should an electrical brownout condition occur. The undervoltage detector also contains a blackout detector section which shuts down the motor more rapidly during more extreme undervoltage conditions.

Abstract: A vacuum controlled valve either in series or parallel with the customary bleed orifice in the vapor flow path from the fuel tank to the charcoal canister of an automobile evaporative control system opens when the engine is operating to direct fuel vapor flow from the tank to the fuel-air inlet induction conduit, thereby to prevent excessive fuel vapor pressure in the tank that would otherwise be released to the atmosphere via the customary pressure vented closure cap for the fuel tank filler spout.

Abstract: A fuel metering system controlling the mass fuel-air ratio in a spark ignition engine in response to fuel and air volume measurements. Linear responsive transducers respond to various temperatures, pressures, throttle positioning, fuel flow, air flow and engine operation for correcting the volume flow measurements of both fuel and air to mass flow measurements. A positive displacement, dual action pump delivers fuel to the throttle body of the engine in response to the mass of the air entering into the throttle body.

Abstract: Each of a pair of electronic semi-conductor switching devices is disposed between a corresponding pair of conductor plates. The semi-conductor devices are aligned with each other, and the complete assemblage is held together by means of a clamp which applies a clamping force to tightly hold each semi-conductor device between its corresponding pair of conductor plates. A spacer arrangement separates the two pairs of plates and includes a spherical pivot bearing seated between a pair of individual spacer plates which are in turn separated from the immediately adjacent conductor plates by means of annual insulating spacers. The pivot bearing permits limited pivotal movement of one pair of plates relative to the other so that excellent surface contact between each semi-conductor device and its corresponding pair of conductor plates is maintained when one plate of each pair is attached to a corresponding electrical terminal fixedly mounted on a control panel into which the assemblage mounts.

Abstract: A snap-in socket for wedge base lamps that avoids the requirement of a quarter turn twist for locking the socket in the panel. Contact members are adaptable to be inserted from either end of the socket. One modification of the contact member utilizes a snap-on hood for providing one electrical return path through a chassis thereby requiring only a single wire to the socket. The contact members further feature wire guide means thereon which function to straighten any bent filament wires on the lamp bulb when the bulb is inserted into the socket assembly.
