Abstract: A synchronized gear box comprises a pinion rotatably mounted on a shaft and an externally toothed hub mounted for rotation with the shaft. The pinion includes a conical friction surface that is in permanent engagement with a conical friction surface of a synchronizing ring. A lug projecting axially from the ring is located in an axial groove in the hub whereby the ring is rotated with the hub, but has limited angular movement relative thereto. During rotation of the hub a ball movable in a radial passage therein is centrifugally forced into engagement with an axially inclined surface the lug thus thrusting the friction surface of the ring into driving engagement with the friction surface of the pinion. When the pinion and hub are rotating at the same speed teeth on the external surface of the synchronizing ring allow an internally toothed selector ring to slide over the synchronizing ring to positively connect the hub to the pinion.

Abstract: An inlet manifold for an internal-combustion engine comprises a chamber having a circular aperture in the top surface thereof through which aperture gaseous fuel is fed from a carburetor. Two adjacent sidewalls of the chamber are disposed at an angle not greater than 90* and are joined by a curved portion, the axis of which coincides with the axis of the circular aperture. The entrance portions of passages which lead from the chamber to the respective cylinders of the engine are rectangular in cross section and the axes thereof converge towards the axis of the circular aperture. The cross section of each passage progressively changes so as to be circular at the outlet end, and the entrance portion of each passage is located on the same side of a plane containing the axis of carburetor and the axis of the throttle valve in the carburetor.
