Abstract: The base support mount for heat pumps and the like machinery is comprised of a top cap portion which contains a depressed area for accepting a protrusion from the bottom of a machine, a hollow central column portion and a ribbed base portion. The top cap, central column and ribbed base portions are separable and thereby permit the central column to be manufactured in various lengths and further allows the different length columns to be interchangeable with the top cap and ribbed base portions. This interchangeability permits the base support mount of the present invention to be easily manufactured in differing heights for supporting heat pumps and the like machinery.

Abstract: A foldable hanger assembly for mounting on a wall. The assembly includes an elongated housing to which is pivotally connected a hanger arm that is stored in the housing when not in use. The hanger arm is dropped to a horizontal position for supporting clothes hanger or the like and a brace is hingedly positioned at one end on the hanger arm and the opposite end thereof is slidably engaged with the housing at a point intermediate its length.

Abstract: Water, with gas entrained therein, collecting in the bottom of the casing of a gas producing well is continuously removed using an ejector in the inner of a pair of coaxial tubes mounted in the casing by continuously pumping drive water downwardly between the two tubes, radially inwardly through apertures in a nozzle body and upwardly through a nozzle at the top of the nozzle body into a suction chamber to draw water from an inlet duct at the bottom end of the inner tube through longitudinally extending passages in the nozzle body; the resulting mixture of drive water, well water and gas being discharged through a multi-stage diffuser and the inner tube to a separator, where the gas and water are separated. The separated gas can be used to operate a gas engine for driving the pump, which feeds drive water to the ejector, and the well water can be re-used as drive water.

Abstract: A fuel metering device for an internal combustion engine, and in which a metering needle, common to a liquid and gaseous fuel chambers having respective inlets for communication with a respective source of liquid and gaseous fuel for the engine, extends between the outlet of the liquid fuel chamber and one of the inlet and the outlet of the gaseous fuel chamber and has thereat a respective valving member adapted for controlling the volume of fuel metered to the engine induction system; and an engine having such device incorporated in the fuel induction system thereof.

Abstract: There is provided in accordance with the invention apparatus and a method for boring holes through carbonaceous deposits.The method involves the step of introducing combustion-supporting gases such as air under pressure through the apparatus installed in a well hole opposite the area to be bored. The apparatus comprises inner and outer flexible tubes with flexible, jointed armour and a directional nozzle which permits it to be bent and change attitude as necessary. The adjacent carbonaceous interface after being ignited is maintained in this condition by the combustion-supporting gas which is supplied under pressure. As the combustion proceeds, the pressure expels the combustion products and the gas injector is advanced along the channel it has previously formed.
