Abstract: An engine for converting temperature differentials to power or for converting power to heating or cooling. In the more obvious use, heat is applied to designated segments of metal belts to cause the designated segments to expand for the conversion of heat to power. If desired, cooling fluid is also applied to other segments of said belts to cause these other segments to contract and thus cooperate with the above stated application of heat in the conversion of temperature differences to power. In the preferred embodiment, two pairs of pulleys are provided. The two pulleys of each pair are mounted on and keyed to a common shaft. The two shafts are spaced apart but are parallel to each other. One of the pair of belts extends around one pulley of each pair and the other belt extends around the other two pulleys. The belts are positioned in planes parallel to each other. One pulley of each pair is larger than the other pulley of the pair to which it is connected by the associated shaft.

Abstract: An improved mason's guide for anchoring and positioning an aligning cord. The guide has a clamp element with a pair of adjustable fingers attached thereto, the fingers being designed to affix the guide temporarily to any one of a variety of masonry building units. The aligning cord is secured at one of its ends to a fixed point and at its other end by the cord being wound around one of the adjustable fingers and between the clamp and a convex washer attached thereon. A neoprene sleeve is located on one of the fingers for accurately positioning the aligning cord and allowing the mason's guide to clamp a masonry unit more securely. The guides may also be used to position an aligning cord at a point between its two fixed ends as is required when an obstruction lies in the path of the aligning cord.

Abstract: The superheater of the invention is provided for the purposes of improving the efficiency and cleanliness of gasoline internal combustion engines which are used extensively and which are the usual motive power of automobiles. The superheater includes a housing or chamber which may be assembled in communication with the fuel supply tank of an internal combustion engine. It includes means such as a connection with the engine cooling system for heating gasoline in the housing or chamber to a temperature above its normal boiling point while the gasoline is held in its liquid state under pressure. It also includes means for controlling the pressurized flow of the superheated gasoline to the fuel input of the engine. In the embodiment illustrated, a heating coil is provided in the chamber so that heated engine cooling fluid may pass through the housing or container and thus heat the gasoline without coming in actual contact with the gasoline.

Abstract: A system for removing oil, water and other adulterants from machine shop scrap cuttings. Scrap is inserted in the upper end of an inclined tumbler barrel and passed through a counterflowing stream of hot gases from a burner located at the lower end. Oxygen is inserted into the tumbler barrel at an intermediate position. The barrel is lined with refractory inserts each having contiguous connecting passages of different diameters. The scrap is raised to a temperature near its melting point and compacted into briquettes while remaining hot. Excess fuel gas flow and combustion prevent the aspiration of air into the barrel and thus prevent oxidation of the metal part of the scrap. As an alternative, the scrap can be melted as it flows from the tumbler barrel directly into a melting pot.
