Abstract: Liquid fuels for internal combustion engines burn more completely after passing across and between metallic surfaces that can electrically polarize the fuels with a temporary electrostatic charge. The placement of the activating components of the fuel line close to the engine permits the fuels to be passed into the engine with the developed electrostatic potential that more rapidly dissociates the fuel molecules during their mixing with air prior to the ignition of the air and fuel mixture.The described liquid fuel treatment device activates the fuels to improve the combustion efficiency resulting in increased engine performance, more power, better fuel economy, easier and quicker starting, reduced knock, a lower octane requirement, a cleaner engine, lower maintenance costs; while achieving lower levels of the regulated engine exhaust emmissions.

Abstract: Apparatus for drilling horizontal drain holes from within existing wellbores is comprised of a flexible rotary drillstring made from a plurality of arcuate elements tightly drawn along a central cable, and of driving and redirecting apparatus to rotate and deflect the drillstring. The elements, engaged to the cable, provide a stiff drillstring which, combined with the rotary drive at the well bottom, permits extensive drilling. A deflection block, precisely fitted to the drillstring and to other apparatus requirements, enables the drilling functions. An alternate drillstring has cylindrical interlocking elements with internal alignment means.

Abstract: A bending press comprising a lower frame member, an upper frame member mounted above the lower frame member, tool holding means positioned in operative association with one of the frame members for holding bending tool means, die holding means positioned in operative association with the other of the frame members for holding die means, a plurality of first hydraulic rams mounted in laterally spaced relationship to be operative between the tool holding means and the associated frame member, a plurality of second hydraulic rams mounted in laterally spaced relationship to be operative between the die holding means and the associated frame member, the first hydraulic rams being adapted to be hydraulically connected together during use for hydraulic fluid to distribute a load applied to a workpiece during use evenly between the first hydraulic rams and provide compensation for frame member deflection during use, and the second hydraulic rams being adapted to be hydraulically connected together during use for hydr

Abstract: A bucket is disclosed for both chipping coal from a coal seam and for removing the coal from the seam. The bucket is arranged for flexible coupling to preceding and succeeding buckets to form a continuous train for rotation through a coal tunnel. Along the side of each bucket there is mounted a cutting blade for dislodging the coal. A ramp on the side of the bucket serves to scoop the dislodged coal into the bucket. When the bucket emerges from the mine tunnel the bottom of the bucket falls away and the coal is unloaded directly into waiting hoppers.
