Abstract: A manual shift transmission having multiple input and output portions is provided with a control having input and output shift rails. A laterally movable control shaft extends axially through cutouts in respective shift rails and carries cams adapted to cooperate with cam follower surfaces on corresponding cutouts to effect rectilinear movement of the shift rails upon rotation of the control shaft. The cams are arranged on the shaft so that the shaft may be positioned to place respective cams in register with the input and output shift rails while all other cams are out of register with the rail cutouts. The shift movement of respective output and input shift rails is overlapped during the rotation of the control shaft to decrease the throw of the shift lever.

Abstract: A dynamic balancing system for rotary elements wherein balance is maintained by remote control of mass distribution during rotation. A fluid balancing mass partially fills three or more annular chambers. A change in mass distribution is achieved by heating the fluid in a chamber and conducting the vapor so produced to the opposite chamber(s) where the vapor condenses. A warmer chamber thereby loses mass to a cooler chamber. Electronic vibration measuring means and control are generally employed to determine which chambers and what degree of heating are required to improve the state of balance. The preferred control is electronic and comprises a stationarily mounted encoding portion and rotationally mounted decoding portion. Power and encoded control signals are transmitted via inductively coupled coils from the encoding portion to the decoding portion.

Abstract: A hydraulic control for a power transmission has a regulator valve for controlling the hydraulic system pressure and a plurality of shift valves for controlling the automatic ratio change in the transmission. The shift valves are urged toward the higher ratio position by a governor pressure.

The modulated pressures are maintained at substantially zero for a portion of the throttle valve pressure range so that upshifting and downshifting will be sensitive to governor pressure and therefore vehicle speed only.The regulator valve is subject to a variable bias pressure which is proportional to throttle valve pressure.
