Abstract: An adjustable hanger for hanging pictures, tools, or the like has an elongated, slotted bracket member having a wall mounting portion at one end thereof. A hanger hook member has a vertical portion with a bolt hole adjacent one end and is adapted to be positioned anywhere along the bracket by means of a bolt member and a resilient washer. The surfaces of the bracket and the vertical portion of the hook member may be roughened or striated to insure better purchase of the resilient washer between those two members when compressed by the action of the bolt member.

Abstract: Land transportation vehicles using pneumatic tires loose air over time, including tractor trailers, private vehicles, race cars and other vehicle classifications. Tire pressure is important, but only a small number of attendants are concerned. Our invention is an automatic device which supplies air to tractor trailer tires using an onboard air supply. This air, supplied to the rotary air chamber system can be adjusted to a desired tire air pressure by the individual driver to suitable levels of load weights, climates, travel speed and terrain. Rotating tires at high speeds build up friction raising tire pressure to dangerous levels. This will be corrected by built in relief valves. To maintain and verify tire pressures each tire is protected by check valves and visible pressure gauges. The rotary air chamber automates, corrects continuously the neglect of proper tire maintenance, adds road safety for users and public alike.

Abstract: An artificial hand assembly for use in training manicurists has a base upon which the hand is mounted at an upwardly extending angle thereto. The hand has removable fingertips having artificial nails therein. In one embodiment the hand is movable with respect to the base about one axis. In another embodiment of the invention, the hand is movable with respect to the base about two axes normal to each other. In still another embodiment the hand is movable with respect to the base in any desired direction or orientation without regard to any discrete axis, by means of a ball and socket connection to the base.
