Abstract: A method of preparing a stabilized fuel slurry is disclosed wherein a petroleum fuel oil is mixed with "run of the mine" coal and with a polysaccharide emulsifier capable of forming water internal-oil high external phase emulsion. The slurry is mechanically mixed to comminute the coal to produce a stabilized fuel slurry with coal particles having diameters as large as about 1/4 inch. The slurry is injected through lances into a blast furnace, the lances provided concentric streams of slurry and steam. The slurry may also be used in other fuel burning furnaces such as boilers, cement kilns, etc.

Abstract: A liquid soap dispensing system includes a closed soap container having a manually actuated dispensing pump carried therebeneath and being mounted on a bracket which has support fingers engageable with a lip on the container bottom for supporting it and a flexible retaining finger engageable with a groove in the top of the container for releasably holding it immovably against the bracket. A bottom wall extends from the bracket beneath the container and cooperates therewith to enclose the dispensing pump and is provided with an aperture to accommodate dispensing of soap therethrough. Refill of the container is by a plastic refill squeeze-bottle with a neck closed by a membrane. The neck is inserted in a wall in the top of the container, and a piercing member at the bottom of the well ruptures the membrane, whereupon soap may be squeezed from the bottle and through apertures in the well bottom, which apertures are too small to permit ready flow of soap therethrough by gravity at ambient pressure.

Abstract: A target type scoring device which includes a target formed of a resilient material such as a net supported by elastic members and a frame, there being a trigger positioned behind the target and reciprocally movable toward and away therefrom. A cam and cam follower arrangement interconnect the trigger and an indicia or score indicating display causing the display to rotate upon actuation of the trigger by an object thrown against the target in a scoring area.

Abstract: A two-part variable compression ratio cylinder is provided having inner and outer sleeves wherein relative movement between the sleeves varies the volume of the combustion chamber and hence varies the compression ratio of the engine. Hydraulic means responsive to the pressure in the combustion chamber automatically varies the position of the inner and outer sleeves to regulate the combustion chamber volume. The hydraulic controls are located entirely in the cylinder head facilitating the conversion of any internal combustion engine without altering the piston size.

Abstract: A vibratory polishing machine for minerals, gem stones and the like in which a carriage is resiliently mounted to a base and is provided with a motor fixedly mounted to the carriage. The motor output shaft is eccentrically connected via a crank to a drum supported on the carriage. Activation of the motor vibrates one end of the drum while the other end of the drum pivotally mounted on the carriage remains relatively stationary. The drum vibration causes materials inside the drum to rotate continuously in a circular path providing a polishing action.

Abstract: An apparatus for accumulating into a group a series of spaced-apart loaves of bread in a bakery conveying line comprises an entry conveyor and an exit conveyor each including a driven belt of interconnected free rollers. Upon the arrival of the first loaf at the exit end of the exit conveyor, the exit conveyor is stopped, with succeeding loaves accumulating behind the first loaf under the continued action of the entry conveyor to form a contiguous group which fills first the exit conveyor and then successive zones of the entry conveyor. As each zone is filled, a corresponding shoe is moved into engagement with the rollers passing through that zone for rotating them to counteract the movement of the entry conveyor belt and relieve pressure on the accumulated loaves.
