Abstract: A mobile automotive servicing apparatus is provided with wheel-carrying axle supporting a frame. A pair of ramps are pivotally mounted over the axle, each ramp having a slidably movable ramp extension associated therewith in telescoping relationship. An air compressor is provided on the frame for moving the ramps between horizontal and tilted positions. The frame also supports a compartment for storing tools, supplies and equipment for servicing a vehicle driven onto the ramps when they are tilted and then moved into serving position when the ramps are disposed horizontally.

Abstract: An aid for positioning a user's head with respect to a remote object is described. The device comprises a visor, having front and back edges, the visor being attached at its back edge to a headpiece. A pair of spaced line markings are provided on the underside of the visor, the markings being located substantially equidistant from an axis extending between the front and back edges and bisecting the visor. The distance between the markings closest to the back edge of the visor substantially corresponds to the distance between the eyes of the user.

Abstract: An internal combustion two stroke engine is provided having at least one cylinder within which a piston reciprocates. The engine is joined to a gear box which includes a ring gear. A pair of gears having diameters half that of the ring gear move within the latter. At least one of said pair of gears is connected to a piston by a pin extending between the piston and the periphery of said gear. An additional pair of gears are fixed to respective ones of the first-mentioned gear pair and are operatively joined to a pinion to which a drive shaft is secured. A turbine and filter arrangement is positioned on the side of the engine opposite the gear box whereby exhaust gases from the engine are directed to the turbine to develop power at an output drive shaft joined to the turbine and to filter pollutants from the gases.
