Abstract: A hydraulic ram unit for a transmission of the toroidal-race, rolling-traction type. The ram (8) is connected to the rollers (45) of the transmission so that the position of the ram within its stroke is related to the angular setting of the rollers and so to the transmitted ratio. The ram pistons (15) move within cylinders (17) the inlet (71, 73) and outlet (72, 74) ports of which are located in the cylinder end walls (24), with the outlet ports axially proud of the inlet ports. If a piston overshoots its normal stroke it tends first to restrict flow through the outlet port and then to contact and obstruct it, so creating firstly hydraulic and then contact forces to resist further overshoot, without substantially restricting the inlet port. Novel constructions for the ram (8) itself, and for the ram cylinders (17) and casing (1) are also described.

IPC: B60C23/04

Abstract: A reliable indication of temperature-compensated pressure is provided from each of the wheels of a vehicle to an operator within the vehicle. A piezoresistive transducer bridge (1) is supplied by a constant current source in one embodiment, and by a voltage of constant amplitude in another embodiment. Voltage to the bridge is reversed on a periodic basis. The use of constant current enables compensation for temperature-induced drift in transducer bridge output. The use of constant voltage enables compensation for ambient temperature, and provides an absolute, rather than a relative indication of pressure or "flatness" within the tire. Voltage polarity reversal permits compensation of amplifier offset voltage. Energy is transmitted to and from the wheel by means of a tuned circuit which is excited by a primary coil (9) when the vehicle's engine is running. The secondary coil (10) mounted on the wheel may be either short-circuited or selectively opened and closed to alter the operation of the primary coil, thus providing an indication of tire pressure, that indication being detected and processed by suitable microcomputer circuitry which may exist on board the vehicle. Most of the active circuit elements of the invention may be implemented in a single   monolithic integrated circuit, which can be attached to a tire valve.
