Abstract: One of several inventions claimed is a method of providing increased traction to the driving wheels of a high speed transportation vehicle. The vehicle is placed within a tubular passageway, equipped with wheels arranged to contact the tube at three or more equidistant contact points, and these wheels are pressed against the inside surface of the tube by means of controlled application of powerful hydraulic pressure. Vertical stability of the vehicle is achieved by a new apparatus comprised of a spoke attached to the vehicle which projects outward to a point adjacent to but not touching the tube, a set of wheels transversely mounted on each side of the spoke, and a pair of L-shaped guide rails between which the wheels roll. An improved wind resisting braking system is claimed which uses extendable baffle plates and air ports from which compressed air is ejected in a direction opposed to the direction of travel.

Abstract: Method of making an index gauge based on a portion of a generally available record to be used for a generally comb shaped apparatus having a slot on one end to engage the center spindle of a record player and having an index gauge that engages a tone arm, to help position the tone arm to select a particular song or narration from a record album.
