Abstract: A starter arrangement for an engine includes a fluid actuated rotary vane motor which is adapted to engage an associated engine. The rotary motor has a plurality of blades or vanes with each of the blades being made from a fiber reinforced plastic material to reduce friction. A sleeve, in which the rotary motor is positioned, has on its inner surface a hard metallic coating to reduce friction. A relay valve member selectively provides a pressurized operating fluid to the rotary motor. The blade material and the sleeve inner surface coating cooperate to enable the vane motor, when it is actuated by the relay valve member, to rotate in the sleeve with a minimum of friction thereby obviating the need for a lubricating agent.

Abstract: Circuitry for use in a voltage measurement and display device provides automatic function change for measurement of AC or DC voltages. Voltage measurement in a predetermined mode (DC, for example), is assumed. Upon detection of an input voltage component exceeding a predetermined threshold of the other mode, (AC, for example), the measurement function is changed to that other mode. Upon detection of a component in the other mode, in a range between the predetermined threshold and a second (preferably lower) threshold, an annunciator is activated to alert the user to the presence of the other mode (AC) voltage, for manual activation of a function-selecting switch if desired. Thus, in a specific embodiment, automatic function changeover is provided upon detection of AC components exceeding a predetermined threshold, along with activation of an AC annunciator.

Abstract: An air suspension system for a wheeled vehicle and particularly for the auxiliary lift axle of a vehicle wherein a trailing arm supporting the axle is pivotably supported at one end to the frame with an air spring operatively connected to the other end of the arm and a cantilever leaf spring rigidly connected at one end to the arm and cooperating with a frame-supported link at its other end to form a mechanism which normally biases the axle to an elevated position and which, in the lowered position of the axle, serves both as an energy store for lifting the axle and as a means of shock absorption.
