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.
