Abstract: A carbureting device for internal combustion engines providing pre-volatilized light gasoline vapor and a means for conserving unvaporized gasoline. An electronic pulsing circuit powers and controls the operation of an array of electric fuel pumps connected to the nozzles of a communicating array of volatilization chambers. Operating electric fuel pumps, through the connected nozzles, deliver spurts of liquefied gasoline spray mist onto ribbed inner surfaces of volatilization chambers. Liquefied mist phase of gasoline and evaporation ribs of volatilization chambers accelerate evaporation of liquefied gasoline spray mist, producing light gasoline vapor in volatilization chambers. Unvaporized gasoline drains from volatilization chambers to a fuel storage chamber and is recycled for change of phase to light gasoline vapor.

Abstract: An adjustable rear bumper mounted device for installing and removing tire chains from vehicles. The device is secured at one end to the rear bumper or similar portion of the car, and carries an elongated belt, webbing or the like wrapped and wound up on a take-up reel which is under spring bias tension. The outer end of the belt is fastened to the rear end of the tire chain, while the front end of the tire chain is fastened releasably to wheel clamps, so that as the car is moved forwardly, the tire chain is wound about the tire for being secured together at its ends when the rotation is completed. The wheel clamps may be either magnetic for holding the end of the tire chain to each side of the ferrous steel wheel, or "H" shaped to clamp onto spokes of "Mag" type wheels.
