Abstract: A system for a two-step activation for a valve includes at least one valve control selector having an output representative of a valve position and a touch sensor having an output representative of a permission to operate said valve.

Abstract: A therapeutic pad holder has a flexible body with a pocket for holding a hot pack, cold pack or cushion. Releasable fasteners on the body and pads separated from the body with elastic members cooperate to retain the holder around a cylindrical member or part of the human body.

Abstract: A method and apparatus to heat-activate hydrogen of water for powering rotational, reaction-thrust and projectile-expulsion embodiments (19, 60, 61, 75) of a water engine (10) with hydrogen energy of water which is spray-atomized and electrically heated internally in one or more hydrogen activators (1). Water-hydrogen electrons of the spray-atomized water are heat-activated up to exponentially greater output heat-activation energy than input activation-heat energy added electrically with power generated from forms of the water engine. A minor portion of the output heat-activation energy of the water hydrogen is utilized for generating electrical current for the input activation heat of the spray-atomized water in the hydrogen activators. Net output heat-activation pressure of water-hydrogen is directed from one or more of the hydrogen activators to one or more use chambers (9) of universal-use forms of the water engine. Rotational features of the water engine preferably employ a turbocam drive (20).

Abstract: A complete machining center has a horizontal machine bed (1) with a vertical-axis trunnion (2) pivotal horizontally with computer-coordination proximate a first-end portion (3) and a traveling tool column (4) with computer-coordinated horizontal X and Y axes and vertical Z tool travel on a compound slide (6) proximate a second-end portion (5) for horizontal access of a cutting tool (12) on the traveling tool column to work pieces on a work-piece rotator (10) and for horizontal access of the cutting tool to work pieces on a vertical-axis milling table (38), either of which are positioned on the horizontally pivotal vertical-axis trunnion (2). A work-piece changer (31) is provided for optionally manual or computer-coordinated work-piece setup, setup reversing and finished-work-piece removal.

Abstract: A rocketjet engine has a light, hollow double-acting compressor piston (35 and 123). It is reciprocated by a smaller-diameter double-acting power piston (51) through a power shaft (52 and 60) connecting them. Up to 90 percent of intake air is routed from a compressor cylinder (36) to a thruster (1 and 106) and the remaining ten percent to a power cylinder (55). Fuel and water are preheated and sprayed into the power cylinder with phase-change injectors 67-70 at ends of compression strokes after complete flame-front propagation to actuate the compressor with combined combustion and steam pressure. To provide steam-propulsion pressure in addition to peak-heat combustion pressure and to cool the thruster, fuel is preheated and spray injected into an upstream combustor (8 and 109) portion of the thruster (1 and 106).

Abstract: A floating fish holding container has flexible open mesh fabric side, top and bottom walls surrounding a chamber for accommodating fish in water. A top ring having buoyant material attached to the top of the side wall floats the container in a body of water. A bottom ring attached to the bottom of the side wall maintains the cylindrical shape of the container in the water. The top wall has an opening into the chamber that is biased to an open position with elastic cords. A draw string is used to close the opening. A releasable locking device on the draw string holds the top wall in the closed position. When the locking device is released the elastic cords automatically open the opening. A plurality of strings mounted on the side walls are used to adjust the length of the side wall to allow the container to float in shallow water without contacting the bottom or weeds in the body of water.

Abstract: A means for pivotally mounting the bellcrank of a bucket linkage between the boom arms of a loader, including pivot castings secured to each of the boom arms, a shaft extending through said pivot castings and the bellcrank, a plate secured to one end of the shaft and bolted to the adjacent pivot casting to prevent rotation of the shaft relative to the boom arms, and a second plate bolted to the other end of said shaft to limit inward axial movement of the shaft relative to the adjacent pivot casting.

Abstract: A shift gate 22 allowing movement of a control lever 12 in a fore and aft plane is provided with a pivotable plate 46 having a recess 60 located in the midsection of said pivotable plate corresponding to a neutral position of a control lever. The control lever 12 will be locked in neutral when the pivotable plate is swung into position and an attached security knob 56 draws the pivotable plate 46 into a restrained position.

Abstract: A double-acting cam drive piston pump-refrigerator having a double-acting expander piston and a compact heat exchange condenser and evaporator with high density arrangement of heat exchange material.

Abstract: This is a deep well drill employing a Nelson air motor, a Nelson engine or other air motor for drilling power at the face of a petroleum or other deep well and having a cable and tube attached thereto and suspended from spools on a drill rig. A cutting container is attached to the drill to remove cuttings without mud. Drills for varying types of rock strata are provided. A type of foldable casing employed permits the use of the same diameter casing throughout the entire well of any depth, including deep wells to over 25,000 feet. Expandable bits at the end of the cable are provided for drilling selectively larger diameters for foldable casing walls and for safety valve and flow control anchors. The bits are also contractable for unobstructed travel up and down the well.
