Abstract: A hand operated hydrostatic throttle & shut-off switch for remotely transmitting signals from a skier's hand to a power-driven ski's engine, comprising of a hand operated master cylinder, a slave cylinder for activating the throttle and a flexible coiled tube through which throttle control and shut-off signals are transmitted between the hand and the engine.

Abstract: A speed-limiting accessory drive system and apparatus therefor for the transmission of torque and diversion and dissipation of excess energy from a prime mover, such as liquid-cooled internal combustion engine, to a cluster of accessories associated therewith utilizing a speed-responsive mechanism wherein the mechanism is comprised of two drum-shaped driving and driven members which simultaneously provide bearing journalling support and frictional engagement one with the other. One form of the invention utilizes a centrifugally partially disengaging speed-responsive mechanism so that regardless of the driving members speed above a predetermined control speed, the driven member is substantially maintained at that control speed thereby driving the accessories at a desired maximum speed.

Abstract: A system for spinning up a nose wheel of an airplane equipped with a Fixed Slip Hydraulic Anti-Lock Braking System, incorporated in the airplane's anti-lock system. The system includes a main wheel pump coupled to a main wheel which is hydraulically coupled to a nose wheel pump-motor.
