Abstract: A submersible deep well pump having two interconnecting chambers slidably receiving a movable hollow piston, each chamber having a check valve wherein movement of the piston alternately opens and closes the check valves allowing liquid displaced by the piston to be progressively moved through the chambers into the hollow piston and to the surface.

Abstract: A floor sanding machine is provided with a pair of sanding discs, each of which is driven by an individual variable speed electric motor. Individual controls on the handle of the floor sanding machine control the speed of each of the individual motors so that the sanding machine can be guided in a desired direction by changing the speed of one or the other or both of the electric motors.

Abstract: A coffee cup and container for a beverage concentrate comprises an expendible cup and a plastic film liner therefor positioning the beverage concentrate between the liner and the cup bottom. The liner overlaps the rim of the cup and is attached thereto so as to form a convenient easily handled section enabling the liner to be removed when the beverage concentrate is to be used as by adding water thereto.

Abstract: A vertically positioned post detachably affixed to a step ladder has a slotted clamp adjustably positioned thereon for holding the bail of a bucket on the step ladder or alternately engaging the rim of the bucket. The upper end of the post forms a safety handle.

Abstract: A machine for receiving mixed concrete from a ready mix truck provides a receiving hopper and an elevator for lifting the material therefrom arranged to discharge it into a classifying rotating drum incorporating a spiral conveyor into which water is sprayed during use. A sump and a secondary conveyor are positioned beneath the classifying drum so that the separated sands, aggregate and other material, washed and separated from the concrete mix, introduced with the cement and waste water are confined to the sump and a separate settling tank from which the fine sands and similar materials can be salvaged.

Abstract: A self adjusting consumable hot top is formed of a pair of bendable shape adjusting sections of a combustible consumable material capable of being wedged into opposed relation in an ingot mold so that the hot top conforms with the shape of the cavity in the ingot mold and when ignited by molten metal poured therein adds heat to the molten metal to maintain a pool of molten metal for filling pipes and cracks in the cooling ingot.

Abstract: A wall mounted tool cabinet easily assembled from a kit of parts comprises three units hinged to one another to form a complete enclosure with each unit formed of four frame sections and a section of pegboard material. Hooks detachably engaged in the pegboard material in each of the units serve to position tools therein to present the tools in side by side array when the units are opened.

Abstract: A patch material for filling and sealing chuck holes in pavements comprises iron scale and aluminum particles, ground ceramic brick and/or blast furnace slag and pitch, the iron scale and aluminum particles producing metal when ignited and suitable temperatures to form a molten liquid containing the other materials.

Abstract: A hot fuel gas generator for an internal combustion engine simultaneously vaporizes gasoline and water in a multi-chambered heated pressure vessel having built in regulators for controlling pressure and volume and delivers the resulting superheated steam and gaseous fuel to the internal combustion engine downstream from the usual carburetor. A single device operating at a very high temperature, for example 1800.degree. F., is used for the simultaneous vaporization of the fuel and water to develop desirable working pressure and volume. The high temperature steam and gaseous fuel positions the fuel molecules at the greatest degree of separation from each other providing the greatest opportunity for contact of the oxygen, the reacting species in the gaseous condition as chemical reactions occur only between particles at the atomic or molecular level and it is necessary for the reacting species to be in actual contact at the time of reaction.

Abstract: A dispenser for chips or coins includes a cylindrical body and a plunger for moving the chips out of an open end of the body. The open end of the body is formed as a thin distortable ring having at least a pair of oppositely disposed detents thereon against which the chips or coins are normally engaged. A movable collar surrounds the lower end and the distortable ring and alternately spaces the distortable ring from a supporting surface so that a single chip or coin may be dispensed therefrom or permits the distortable ring to engage the supporting surface about a chip or coin to be reinserted in the device.

Abstract: A material is disclosed which is particularly suitable for sealing the gaps between the component parts of ingot casting and like molds and for bonding core parts together and filling cavities in stools on which ingot molds are positioned, the material comprising a mixture of ceramic and consumable materials with or without exothermic materials as desired and a wetting solution so as to form a paste-like consistency conveniently packaged in shaped flexible plastic or paper containers which may be readily applied to the indicated areas.

Abstract: A boring device is disclosed wherein a boring bit is rotated as it is advanced and supplied with water through a hollow interior to facilitate the boring operation. A rotary connection introduces water into the hollow boring bit and its support means from one side thereof through an apertured sphere secured to and revolving with the support means.

Abstract: A shelf and garment hanger rack for childrens' clothes, hat and gloves is adjustably suspended from a garment hanger bar in a clothes closet, and positions the shelves and a garment hanging bar in relatively low location in the clothes closet so that they can be easily reached by a small child.

Abstract: A continuously hollow edge member is applied to the edges of the structural portions of a chair to protect and finish the same and provide visual indication of desirable locations for securing the welt and upholstery thereto.

Abstract: An adjustable anti-rolling shipping rack for steel coils consists of a metal body flanged on its longitudinal edges and having a plurality of apertures inwardly of its ends adjustably receives a pair of secondary metal body members in oppositely disposed relation, each of which have upstanding triangular abutments on their outermost ends and offset portions on their inner ends engagable in said apertures.

Abstract: A shearing tool for use in dismantling steel structures such as multi-story buildings takes the form of a large heavy inverted U-shaped steel member of a size enabling it to be elevated and dropped on a horizontal floor beam for example adjacent a vertical column to shear the same therefrom.
