Abstract: A method of playing a game, including registering a plurality of players to play the game, wherein the plurality of players are registered as digital vehicles, creating user profiles based on registration information of the plurality of players, presenting a race link to the plurality of players, notifying the plurality of players of a beginning of the race, unveiling a track to the plurality of players on which to receive the digital vehicles, and accelerating the digital vehicles around the track based on player input of assigned values into assigned value spaces of the track.

Abstract: In a transmission having input and output shafts drivingly connected by fluid pressure operated ratio establishing devices an improved centrifugally actuated valve is provided to disestablish the driving connection maximum angular velocity of the input shaft. The valve includes a sphere disposed in a stepped bore which sphere is spring biased to a closed position for normal operation and which shifts in response to centrifugal force to an open position in a fluid flow path thereby exhausting the drive establishing device and also being flushed of any contaminants.

Abstract: A torque converter and multi-disc lock-up clutch has a pair of clutch discs splined to the input shell of the torque converter, a friction disc splined to the clutch piston intermediate the clutch discs and a friction pad secured to the clutch piston. The clutch piston is drivingly connected with the turbine of the torque converter. The clutch is controlled by fluid under pressure delivered to the torque converter such that during disengagement, the fluid passes between the clutch discs and the friction disc prior to entering the torque converter.

Abstract: A hydromechanical transmission in which the first and second drive ranges are input-split drives. In one embodiment the transmission includes a hydrostatic portion comprised of two hydraulically interconnected, variable displacement, hydraulic pump-motor units and two planetary gear sets which are controlled by a brake and a clutch to provide the two ranges. In another embodiment a third planetary gear set and a second clutch are added to provide increased torque coverage in first range and also provide a third drive range. In both embodiments the speed ratio within the drive ranges is varied by controlling the displacement ratio between the pump-motor units. The shifting from one drive range to another occurs at synchronous speeds, thereby reducing the shift energy absorption required in the clutches and brakes.
