Abstract: In a peripheral fluid pump designed for operation submerged in a vehicle fuel tank and comprising an impeller raceway with an outer annular channel, appropriately placed stripper abutments and an inlet and outlet on opposite sides of the raceway in communication with the annular channel, an impeller in the raceway has a hub and a plurality of vanes projecting radially outward into the annular channel. Each vane has front and rear sides in the direction of impeller rotation which are parallel to the axis of impeller rotation, an inlet side adjacent the inlet side of the pump forming an acute angle with the front side and an outlet side adjacent the outlet side of the pump forming an acute angle with the rear side.

Abstract: A fan in a duct driven by a permanent magnet D.C. motor powered by a constant voltage source varies in speed according to the airflow through the duct. The current drawn by the motor is a direct function of the air speed and the density. The motor current is measured to provide a measure of mass airflow.

Abstract: A mechanical switch having a plurality of sequentially energized outputs responsive to the displacement of a push button or other linear actuator comprises an arcuate array of fixed contacts on a rigid printed circuit board and a single movable contact comprising a helical spring member with its axis normal to the circuit board and having one end contacting one of the fixed contacts. The spring rate of the spring progressively varies along its length such that when the spring is compressed by an axially applied force the spring sequentially and progressively contacts and bridges the fixed contacts thereby sequentially engaging the fixed contacts.

Abstract: An electric gage driving a pointer has an extended spindle so that the gage movement can be substantially spaced from the pointer. The gage includes a spindle, an armature driving the spindle, a bobbin supporting a bearing for the spindle and electrical coils around the bobbin. An outrigger support remote from the bobbin and adjacent the pointer holds another spindle bearing which may be misaligned with the bobbin. The bearing on the bobbin accommodates the misaligned spindle.

Abstract: An air core electrical gauge incorporates on the bobbin an annular biasing magnet magnetized in a direction to return the meter pointer to zero in the absence of a gauge driving current. A method of manufacturing the gauge includes magnetizing the biasing magnet after it is secured to a bobbin portion but optionally magnetizing the guage armature at the same time.

Abstract: A push rod and tappet assembly for a cam actuated pump in which a tappet having a barbed shank is lightly press fitted, during assembly, part-way into the hollow end of the push rod so that during the initial operating cycle of the pump, as the cam on which the tappet rides rotates through the first cycle of rotation, the pump piston to which the push rod is connected bottoms out and the shank of the tappet will then be forced further into the push rod to a position to thereafter provide substantially zero clearance in the pump.
