Abstract: A rear steering three-wheeled toy vehicle includes a frame which is propelled by a pedal-driven front wheel assembly rotatably mounted on the leading end of the frame.A rear steering assembly having a pair of rear wheels is pivotally mounted at the trailing end of the frame for turning movement about an inclined pivot pin. Lever controls are operatively connected to the rear assembly for turning the same in requisite direction about the pivot axis. A stabilizing arrangement reinforces the pivot connection formed by the pivot pin intermediate the rear assembly and the frame. This arrangement includes a support member, opposite ends which are detachably connected to the frame and to one end of the pivot pin. The arrangement also includes a support rod, opposite ends of which are detachably connected to the rear assembly and to the opposite end of the pivot pin.

Abstract: A process of diffusion bonding aluminium alloy parts uses zinc and copper layers, optionally with a tin layer, or magnesium and/or zinc layers as an interlayer material between the parts to be bonded. The interlayer is preferably formed by precoating one or both of the parts.
