  • Variable speed frictional drive transmissions
    Patent number: 4667525
    Abstract: Variable speed frictional drive transmissions that basically depend on driving balls arranged in constant rolling frictional contact with a pair of inner and a pair of outer concentric and axially separable ball races are improved by the provision of (1) new speed control units for changing the relative positions of balls and races to produce desired speed changes and (2) new cam and roller units for maintaining the balls and races in forced contact even when the transmissions are under no-load condition. The new transmissions are characterized by (A) outer and inner circular concave race tracks and (B) a simplified hydraulic feed-back control mechanism which displaces the outer control race only in the direction of speed increase, while its opposite displacement is actuated by torque forces plus spring pressure.

  • Fluid transducer
    Patent number: 4077267
    Abstract: A fluid transducer including a reciprocatory piston member and a drive mechanism for converting reciprocation of the piston member into rotation of a rotary member coupled to the mechanism, or vice versa. The drive mechanism includes a first elliptical member centrally mounted within said transducer and a second elliptical member rotatably mounted in engagement with said first member and arranged for reciprocation with said piston member. As said piston member reciprocates said second member rotates with respect to said first member to transmit motion between said piston and said rotary member coupled to the drive mechanism.

  • Fluid transducer
    Patent number: 3971259
    Abstract: A fluid transducer including a reciprocatory piston member and a rotary member, and a drive mechanism for converting reciprocation of the piston member into rotation of said rotary member, or vice versa. The drive mechanism includes a first elliptical member rotatable with said rotary member and a second elliptical member rotatably mounted within said transducer and arranged for reciprocation with said piston member. The elliptical members are retained in engagement, and rotate in unison as said piston member reciprocates with respect to said rotary member to transmit motion between said piston and rotary members.
