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 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 water-hydrogen engine system runs on hydrogen energy of water that is spray-atomized and heated electrically in a hydrogen activator (1) to heat-activate water for releasing hydrogen energy. At elevated temperatures employed, steam is over 95% hydrogen pressure and less than 5% oxygen pressure, although about 89% oxygen by weight. While remaining molecularly associated with oxygen in gaseous H2O hydrogen is heat-distanced from the oxygen. The heat-distanced hydrogen proton nucleus is heat-weakened for allowing hydrogen electrons to be activated exponentially per level of heat added. Hydrogen pressure typically an order of magnitude greater than combustion pressure of known heat engines is directed from the hydrogen activator to a pressure chamber (5) of forms of gas-powered mechanisms.

Abstract: A combustion-and-steam engine system has a phase-change water injector (1) through which water is spray-injected into combustion gases in a combustion chamber (2) of a Nelson Engine (79) or any type of heat engine with either rotational or thrust power. A steam tube 45 in fluid communication between an injector orifice (25) and an internal periphery of the combustion chamber can be heated with resistance heat from an engine-electrical source (46) to provide phase-change of water en route to the combustion chamber in the steam tube. An injection-metering valve (22, 25, 26, 43) has a return spring (31) with pressure regulatable by an adjustment means (32, 33, 36, 37, 38, 40) to select flow rate past the injection-metering valve to a return tube (57, 74) without requiring lubricity of water or other fluid under high pressure.

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).
