A transmission control system includes torque distribution control unit 50, differential (20) and clutch (27). The clutch (27) acts between output members of the differential (20) whereby torque is transmitted to front and rear wheels at a distribution ratio determined by the torque transmitted through the clutch (27). The control unit (50) operates the clutch (27) so as to distribute the torque a...

A split tire mold having a tread ring in which provision is made for venting air circumferentially across the inner surface of the tread ring so that the air escapes from the parting line of the mold halves, dispenses with widely used, conventional, radially protruding vent stubs. The air is vented through "butterfly-shaped" or "double-wedge-shaped" arch-vents which provide passage for trapped air...
