Abstract:
A turbine apparatus having a stator and a rotor mounted for rotation relative to the stator. The stator has at least one groove facing the rotor and the rotor has at least one groove facing the stator, the direction of each of the rotor grooves intersecting the dirction of a corresponding one of the stator grooves to form a channel for receiving a ball driven by a propelling fluid to cause the rotor to rotate as the ball travels along the channel from an inlet to an outlet thereof. A return passage returns the ball from the channel outlet to the channel inlet in response to gravity, a portion of the propelling fluid, or a moving mechanical element. The stator groove may be straight and the rotor groove cirved or the tator groove may be curved and the rotor groove straight or both the stator and the rotor grooves may be curved.

Description:
BACKGROUND OF THE INVENTION 
     Reciprocating apparatus in the form of positive displacement compressors or engines in which pistons move in cylinders are all worked in conditions of high friction between moving adjoined surfaces that require lubrication that is usually applied in environments of considerable heat. When used for the movement or compression of some gases, the oxidation of the lubrication is objectionable and contributes to the friction condition and the normal heat escalation of compression. This friction adds to the requirement for cooling the gas product that is compressed and to also increases the the cooling requirement of the engine or compressor block itself. 
     In an opposite sense the fan-like turbine structures that employ blades and impellers moving in close proximity to a surrounding stator have no friction factor but are not positive in displacement and are operated at extremely high speeds to overcome the slip-bypass in the space between blade tips and the stator vanes. This often involves the addition to the turbine shaft of an elaborate and precision gear train reduction system to bring speeds down to usable operational levels. 
     In many of the gas pumping and refinery situations, line drive dependence is upon combustion engines as the prime movers for the pumping apparatus used. These waste as much as 75% of the energy input in expended heat energy that goes up the exhaust stack. Electrical prime movers are more efficient, but there is always a potential for a spark-generated explosion and, in the refinery atmospheres, corrosion problems as well as explosion proofing make these electrical drives high in capital cost and costly to maintain. 
     In each existing instance, there is a great heat loss in the compressor itself as well as the heat loss in the driving engines or motors, so efficiency is frequently as low as 40 percent. Much of the heat generated in compression is transferred to the gases being compressed, leading to substantial work and cost involved in ancillary cooling equipment required to bring down the temperature of the compressed product gas. An example is Natural Gas that, when recompressed for delivery in a pipeline, must be cooled to about 100 degrees F. before it can be put back in the line and the gas used in refinery processes that require compression, where heat input is critical, also require elaborate cooling means before return to the process. 
     The equipment associated with this invention involves less in capital investment because it is smaller and more simple in design and therefore it is more easy to maintain. 
     In refinery practice there is a requirement for the high pressure compression of hydrogen. When this is done with conventional compression techniques each of several compression steps must be followed by high output cooling apparatus that has a significant energy input and is again highly capital intensive. 
     SUMMARY OF THE INVENTION 
     The Nucleate Steam Bubble 
     This is a steam by-product normally associated with boiler tubes, but is also visible as the first indication of boiling in a tea kettle. This bubble can be generated in any boiler water or created from the water associated with gas combustion exhaust. It can function as a lubricant for moving parts while exhibiting considerable pressure if confined in a small space. The nucleate bubble thus generated serves as supporting means between pistons and cylinders of a pump, compressor, engine or turbine rotor, and even for support of fully enclosed sealed rotating cylindrical forms that can turn on this bubble support without bearings or seals in a fully closed and sealed chamber. 
     The Perforated Piston&#39;s Outside Diameter 
     Nucleate steam bubble generation occurs around this Piston&#39;s outer surface as the bubbles expand into the laminar space between the piston and cylinder and its escape contributes to the propulsion force driving the piston. This propulsion happens when pressure is applied to drive the piston. The steam or gas combustion pressure moves into large openings at one end of a shell/like piston and along wall porting and manifolds to exit from small diameter perforations around the piston&#39;s surface. The steam escapes from the piston perforations to form nucleate bubbles at each hole opening on the piston&#39;s surface. Each bubble exhibits very high pressure as the steam explosively expands in this finite dual temperature space between the cylinder wall and the piston&#39;s surface. If the piston&#39;s driving pressure is distributed efficiently inside the piston and the bubble perforation orifice areas total less than the input area to the piston interior, this propulsion effect can be achieved successfully. The escape space area between the piston end and the cylinder wall would normally be the circumference of the piston multiplied by a few thousandths of an inch with the consequence that the velocity of steam escape expelled from the rear of the piston as it moves forward would normally be increased 25 to 50 times and provide this contribution to driving propulsion. The tendency is for the steam inside the laminar space to be drawn to the trailing end of the piston by the shear between the opposed moving surfaces of the piston and cylinder walls. This tends to minimize escape from the front end of the piston as it works against the compressible product. The compression pressure further inhibits nucleate bubble steam escape from the working piston end. This can be further reduced with mechanical means employing an expanding bellows configuration at the front end of the piston actuated by the driving pressure. This can reduce the laminar space between piston and cylinder at one end to as finite a dimension as one thousands of an inch thus limiting nucleate bubble steam escape in this one direction, while still maintaining a mechanical clearance. 
     Placing a slight taper of 5 to 8 degrees off the axis of the piston end and extending approximately 1/4&#34; for each two inches of piston diameter provides a nozzle-like expansion area between the piston and the cylinder wall to help in controlling the expansion of this explosive high pressure bubble mass. 
     This bubble form also provides a pressure seal interfacing the compressed product and provides suspension for the piston as the bubbles expand explosively in the laminar space between the piston surface and cylinder wall. The bubbles, unlike other lubrication means, add a minute amount of water to the compressed product that can be ignored, or easily removed. There is no contamination from the oxidation of lubricants. 
     This nucleate bubble injection is used as a substitute for bearings as in the Rotating Valving Cylinder of this invention that encloses pistons. The perforations are placed at the cylinder ends as well as around the periphery for this free running cylinder suspension that is accomplished without bearing or seals. In a like manner nucleate bubbles are used for axial bearing support of the rotor shaft in the Toroidal Turbine of this invention. 
     Unlike conventional compression apparatus, Balls are used as a form of piston as well as the Perforated Piston described in the method of this invention. 
     Ball Projectiles Employed as Pistons 
     Balls used for this purpose are handled in a way that permits rolling rather than sliding in curving cylindrical-like conduits of special geometry. 
     For lightness these balls can be hollow and made from thin wall Titanium metal and to relieve inside pressure, versus that outside the balls, they can have a small plurality of holes piercing the walls for pressure equalization and still function efficiently. 
     To work in substitution for a piston, a ball must fit a cylindrical path just as a piston does but, unlike a piston, it is desirable for a ball to roll along this path which it doesn&#39;t do well because of the friction on one side. This grows out of the fact that it can only roll on half of the path circumference. The ball rolling motion conflicts with the opposite half side of the cylindrical conduit. 
     The Projectile Ball Conduit 
     Ball conduits as paths for the movement of the balls of this invention are in effect long curving cylindrical enclosures to create long strokes that can far exceed that of a normal cylinder which has practical length limits. These conduits are provided with a difference in circumferential area between the two half sections as seen in a cross-sectional view. Inside these two dimensions the balls can roll along the closely fitted circumference portion easily because of a slight clearance between the ball&#39;s diameter and the larger opposite half surface circumference. This clearance eliminates the friction between the opposing rotation of the ball respecting that half surface. To augment this, a nucleate bubble generating slit is at a mid-point of this larger circumference in the conduit wall and here a line of bubbles are generated and swept up by the speeding ball to accumulate and be driven into the space between the ball&#39;s surface diameter and the larger circumferential area. In this way the bubbles provide support as small pressurized spheres in themselves that provide a &#34;rolling&#34; contact in a manner not unlike a number of ball bearings rolling between the ball line contact and the conduit wall. Thus they turn under the ball projectile in a proper rotational direction with minimum friction occurring as the ball is driven by the pressure applied behind it. 
     As employed in the Engine/Compressor or the Toroidal Ball Turbine, the projectile ball conduit has a like geometry that facilitates nucleate bubble generation with use of the linear slit fed by a small long tube-like manifold that runs parallel to the ball transporting conduit. The slit provides a propagation line for the generation of bubbles in a manner not unlike the perforations. 
     The Toroidal Turbine apparatus of this invention is radically different from the Engine Compressor form described above, but does employ the projectile ball, the conduit and in some instances a latching or sprage-like ball reversal block means. 
     The Engine/Compressor 
     This apparatus of this invention uses Ball Projectiles and Pistons in a combination and form wherein either one can be used before the other depending upon the requirements of the application respecting pressure and volume differences. 
     In the form described in the following Engine Compressor design, natural gas combustion is the driving force that propels the projectile balls successively with pressure pulses so each compresses the hot exhaust gases that has driven the prior ball passage through the conduit and into a pressure receiver from which it is valved to a space between pistons that, as they are driven away from their center position to perform the work of compressing the product steam or gas in the cylinder space at their opposite ends. The purpose is to use this hot exhaust gas heat rather than sending it up the stack and to create an expansion of the gas as the pistons&#39; driving force so the expansion creates an endothermic condition to cool the compression function rather than add heat to the compressed product as is normally done in the conventional compressor. 
     It is desirable to contain the entire mechanism in as compact an apparatus as possible to achieve the maximum thermodynamic control and effectively utilize the endothermic feature described above. For this reason an unusual valving system is employed. 
     Revolving Valving Cylinder 
     The cylinder of this invention is a normal piston enclosure, but also serves as the entire valving means and has peripheral porting that provides for the handling of all gas input and product output for the work done. The rotating alignment of ports in the apparatus greatly simplifies the synchronized valving functions required. The stepping rotation of the cylinder has no effect on the sliding movement of the pistons that it holds inside. This revolving cylinder is axially mounted on nucleate bubble &#34;bearing&#34; means as noted earlier and end perforations expel bubbles providing an &#34;end position centering&#34;. This permits full sealing inside a stator body except for the bubble exhaust orifices so the stator can surround and enclose the cylinder entirely. The compressed product passes through ports that are timed to open intermittently to static piping in the stator for delivery to a receiver. The cylinder turns in proper timing with other events which sychronization is accomplished by its geneva ball stepping drive. 
     Geneva-like Stepping Gear Ball Carrier 
     This Geneva Gear is so-called because it provides an intermittent stepping function as it holds a plurality of ball sockets or latching devices mounted around its periphery. These in turn hold the projectile balls and serve in their ejection into the conduit path ahead of gas pressure and the driving pulse. A latch in this gear-like element catches the ball at the end of its conduit excursion and grips it securely until the impact of a recovered ball overcomes this clamp and drives a new ball into the pressure stream. The force of pressure ahead of the ball as it is completing its conduit excursion and its impact in the recovery latch moves the Geneva Gear one step and, because it is an integral part of the Rotating Valving Cylinder, this too moves one rotational step with this action which is the prime synchronizing function of the apparatus as each step aligns different ports of varied size for release, transfer and admission of gases to various functions in the apparatus. 
     The movement of the ball in the first stage compression function delivers the ball accumulated and compressed hot exhaust gas between pistons in the Rotating Cylinder described which causes them to move apart with the hot gas expansion and compress a product gas at the opposite ends of the pistons in the cylinder. The movement of the Projectile Balls and the Geneva Gear assembly that in turn rotate the Rotating Cylinder perform all the functions required for the drive and compression of product gas. 
     The Natural Gas Combustion or Steam Driven Tower Compressor 
     The Tower Compressor comprises a tall cylinder and a single piston that is driven upward in a long stroke by natural gas combustion or steam expansion. Normally these would be used in a group of units synchronized to function together. The cylinder is wrapped with a steam coil of a larger diameter than that of another smaller tube coil that wraps the hot exhaust pipe carrying off the exhaust gases from Natural Gas combustion. When Natural Gas is used for the drive, this exhaust and the associated small diameter coil provide for preheating of the exhaust steam delivered from a turbine. This exhaust pipe&#39;s temperature is about 1,500 degrees F. and adds heat to the steam. With delivery of this heated exhaust steam to the larger diameter coil on the cylinder there is expansion in this tube which creates an endothermic condition for control of the compression cylinder temperature. Conversely the compressed steam can be passed through the coil of the gas combustion exhaust pipe heat exchanger coil for the addition of heat to the steam before return to the turbine. The piston used is the nucleate bubble perforated form, is free and does not require lubrication. 
     A plurality of the Tower Compressors can draw in very low pressure steam in sufficient volume to provide a vacuum draw for a conventional turbine and provide high pressure and temperature steam for reinjection to the turbine. 
     Injecting this steam compression function into the cycle of a power plant is not unlike the use of a compressor in the aircraft fan-jet engine cycle in that it adds a stage to increase steam production before the phase change to water. 
     Compression of steam is made possible because of the unusual use of a free piston and the nucleate bubble support that eliminates most friction and the need for lubrication. The pistons of this invention are not used with piston rod connections so there is no possibility of a water condition causing a crash. 
     If low pressure/temperature steam were available as generated in a solar energy system it could be employed as the make-up steam requirement for steam compression using a gas combustion compression system of this type. In a more intensive effort a saturated steam solar plant could provide the start-up steam pressure for high pressure compression production in a medium size turbine/electrical system. 
     The Toroidal Ball Turbine 
     Here a large number of balls move continuously in a single direction around a common toroidal path comprising a plurality of helical loops, arranged so a part of each loop&#39;s path crosses an arc of the outside circumference of a rotor and an arc of the circumference inside the bore of a stator. The adjoinment of this stator and rotor assembly provide adjoined surfaces having half-round grooves for enclosing balls in the intersection of the two grooves. In this pathway the balls move along the half-round grooves in the bore of the fixed stator effectively making a key-like rotor shaft. These extend from one end to the other. The half-round grooves between the two provide a full round opening at only one point or intersection along their lengths between the stator and the rotor. This occurrence allows a single ball to enter as the opening occurs in rotational alignment as the rotor turns and then be retained as it moves through the length of the adjoining fit between the rotor shaft and stator bore. Each groove of the rotor can optionally trace a spiral around the rotor periphery with a &#34;lead&#34; consisting of one turn for the rotor length or a segment of spiral around the circumferential length of the rotor. In the preferred form of this invention the segments should not make more than one full 360° turn around the rotor or inside the stator. The angular relationship between the opposing left hand and right hand grooves between the two determines the torque or turning force the rotor develops as created by the pressure applied against the area of the balls as they roll in the grooved paths between the fixed stator and the movable rotor. Conversely, if the shaft is driven to turn the rotor&#39;s grooved circumference, the ball areas may be driven to compress a fluid so that the toroidal turbine may function as a compressor. The grooves inside the stator bore can curve in an opposite direction as described, or simply be straight as opposed to the angled grooves of the rotor. The angle of attack against the grooves as applied by the balls can be varied from as little as 10 degrees to two opposing 45-degree grooves. As all of a plurality of balls enter all of the aligned openings at the stator/rotor end with pressure applied behind them, the total force applied is the sum of all of the balls&#39; diameter area and they function like a plurality of pistons. As the ball moves along the rigid stator path and is held in the half-round pathways of the rotor, a matching full round opening traps the ball causing it to remain aligned while it moves in rolling contact at this one point or intersection that forms a full round opening between the opposing moving surfaces. A plurality of balls, one introduced from each helical loop, can thus enter a plurality of aligned openings at one end of the stator/rotor at the same time and, after entry pressure, can be continuously delivered into and along the half-round space of the rotor to drive the ball along the groove to turn the rotor with the total force of all the balls applied. Exhaust openings for the driving pressure are at the end opposite the ball entrance where the rotor grooves terminate. They can be in the rotor or the stator. The balls exit through a full round opening in the stator to start the return path to the starting point. In the preferred form of this invention the half-round grooves in the rotor and the the stator exhibit the same geometry as that associated with the ball conduit of other apparatus described earlier, in which there is a dimensional difference between the two halves so a bubble generating slit can be provided along the center of the larger which can optionally be the grooves of the stator or the rotor. This facilitates ball rotation and minimizes friction created by ball roll speed variation. In the preferred form of this invention there would normally be twice as many half-round openings provided in the rotor as in the stator to afford a fast loading of a new ball series for the transit along the length of the two parts. The fit between the rotor&#39;s outside diameter and the stator&#39;s inside diameter require very critically ground or lapped surfaces equal to that of hydraulic metal valve surfaces, because these two faces do in fact require a liquid-tight slip fit, and both diameters must meet a T.I.R. or total indicated runout criteria suited to maintain the seal of the lands surrounding the half-round opening interaction and contact during rotation so pressure can be effectively held. 
     An option in the solution to this critical fit is the introduction to the lands of either the stator or the rotor of the perforated surfaces with an internal manifold means to provide nucleate steam bubbles into this laminar space as a sealing means between the lands of the rotor and the stator. 
     What has been described is the preferred form of this invention. It can have alternatives. For example, the position of the rotor and stator are reversed such that the rotor is external to the stator. 
     Spiral grooves can be used in the stator with straight grooves in the rotor or spiral grooves turning oppositely can be used in both. 
     The groove spacing around the rotor or stator can be considered as divisions 360 degrees. With 36 divisions in a large rotor, for example, each groove would constitute a 10-degree division. The division number and this degree spacing will determine the rotor length to accommodate one complete revolution of each groove if this were a requirement, however a groove does not necessarily require one complete rotation and can represent only a portion of one full turn. Each groove may traverse less than 360 degrees of arc. For example, a rotor or stator groove maybe a segment of a spiral and turn through only 10° of arc. The ball return can be dependent upon gravity, or a planetary gear system can be employed to a plurality of alternately static and rotational annular shell members enclosing the shaft rotor so grooved segments in these can drive the balls along a return path providing a unit that can operate independently of its spatial orientation. The ball return can also be accomplished by directing the exhaust pressure through the grooved return pathway as a means to power this return transit. 
     Method and Appratus Forming this Invention 
     In all present day reciprocating engine and pump apparatus, there are the problems of generated heat as discussed earlier which must be controlled with heat exchange methods and lubrication. Other than the heat of gas combustion, a major heat source is caused by the friction between moving parts. When high pressures and temperatures are attempted in compressors, the lubrication of these hot surfaces becomes virtually impossible and, even with intense circulation of high temperature resistant oils and larger coolers pulling the temperature down before recirculation, such attempts have usually failed. Using a cooling oil for this purpose is very difficult and costly to accomplish. Even when all this is done efficiently there is a gradual tendency to carbonize and leave deposits on pistons and cylinder liners that are troublesome. 
     There are rigid limits on temperatures allowable in such equipment. 
     In contrast to the conventional reciprocating engine and pump forms, this invention makes use of the nucleate bubble procedure in which there is minimum friction and little or no requirement for lubrication. The pistons and rotary parts work with a laminar layer of explosive high pressure nucleate bubbles forming and confined in this finite space between the moving part surfaces, and these are delivered into the space through small perforated openings or slits in adjoining surfaces. This method provides for friction and lubrication-free support of moving parts as outlined in the foregoing Summary of the Invention and in my co-pending U.S. patent application Ser. No. 08/653,967. 
     There is also described in this earlier work use of piston assemblies in which a plurality of piston and ram parts are arranged in annular positions of rams or pistons within pistons in complex forms that would be so heat-productive in normal applications as to be totally impractical. Here the friction and lubrication-free means make such piston assemblies possible in the production of very high pressures and temperature. 
     This type of compression can be applied in an electrical power plant with a change of energy from that of a boiler to a gas combustion-driven compressor or even a high pressure steam-driven compressor for the creation of high heat and high pressure steam with use of the spent steam from a turbine drive. When the spent steam leaves the turbine as a vapor, it is exhibiting a low vacuum condition of 2 to 3 inches of mercury and a temperature of about 200 degrees F. The steam has nearly completed the phase change to water and normally is run through cooling condenser units to bring it down to water after which it must be reheated and pressure injected into the boilers. This vacuum condition occurs because of the water falling in a column below the condenser. This is eliminated in the compression procedure of this invention, and the steam take-off from the turbine would require a 1 pound pressure rather than a vacuum condition. It would also require and logically have a slightly higher temperature. 
     There are a great variety of apparatus applications for this method of piston and ball projectile or piston support in cylinders as used for the transfer of energy. 
     The four methods cited and illustrated here each have a series of possible apparatus forms, but only one is described for each of the four applications mentioned in the foregoing Summary of the Invention. 
     The Engine Compressor 
     While essentially the same, there are two forms of this apparatus, one in which the ball function occurs before input to pistons and the second in which the piston function precedes the ball compression. 
     One relates to the pumping of natural gas along pipelines. 
     The other would apply in refinery service. 
     Both of these make use of the combination ball and piston apparatus described as the Engine Compression, but with an opposite geometry in which one has the ball phase before the piston and the other the piston phase before the ball. In the latter a higher pressure is achieved and in the former lower pressure and high volume. 
     In the low pressure Engine/Compressor of this invention as illustrated and described, the hot exhaust gas from the first ball drive stage is not exhausted until after it has been expanded between pistons in an endothermic action that reduces the heat applied to the pistons and therefore does not add heat as would be the case in a normal compression function. When this very hot gas is finally exhausted, its heat has been reduced to approximately 500 degrees F. or less. This is a great advantage over existing compression apparatus. 
     In the Engine/Compressor unit when the driving force is natural gas combustion, the low temperature water vapor or low pressure steam can be preheated and partially pressurized by passing it through the center of the gas combustion chamber that momentarily has temperatures as high as 1,200 degrees F. The combustion chambers temperature can be controlled in this manner and some of this high heat imparted to the steam prior to compression. 
     The ball and piston technique of this invention provides the means to magnify greatly the compression effect with use of large piston diameters and short strokes as the propelling means for proportionately smaller diameter balls functioning as piston-like projectiles driven along a long compression path, that is effectively a long stroke, with great speed and force to compress the residual exhaust gases ahead, as captured between the ball excursions. This is an opposite configuration to that described above 
     If the propelling media is exhaust gas from a natural gas explosion, it can, for example, be used to propel the ball and drive it along a long circular or reducing radius spiral track to add speed so that it is driving against the a portion of the residual exhaust gas that has propelled the previous ball fired along this track in the prior firing. As described earlier, the prior ball&#39;s trip has driven pressurized gas over a pop-off or relief valve as it moves to return to its point of recovery and latch into a vacant ball socket in the periphery of a geneva gear where its latching impact provides a one-step movement of the geneva to open a new socket vacancy. The ball has left a trail of residual medium pressure exhaust gas along the conduit track for the following ball to compress. To drive the ball fuel gas is injected into the combustion chamber with compressed air and ignited. High heat is generated as the gas suddenly expands behind the ball that is held in a retaining grip in the geneva. The pressure instantly causes the ball to overpower this clamp. With release, the ball is now projected at high velocity to sweep up the residual hot exhaust gas along the conduit track drive into a shunt and across a relief valve to a receiver. This accumulated exhaust gas from the receiver vessel is pulse-released into a space between a very large pair of pistons for expansion. The action of compression reduces the said ball&#39;s speed so it can re-enter and latch itself in a geneva socket with a reasonable force that step-moves the geneva gear to brings a vacant socket into position while 180° around the geneva a new ball is moved in the firing position on the other side of the geneva circumference. 
     In this way a portion of the residual heat of the hot exhaust gas is put to use rather than simply blowing it up the stack from the combustion point as in normal engines that completely loses all of this heat energy. The exhaust gas temperature is in the order of 1,500 degrees F. which normally radiates through the stack walls before flowing to the atmosphere. The ball compression drives this hot gas into an accumulator vessel making the termperature even higher. This building temperature is controlled by flowing low temperature gas or steam vapors over the surfaces of the ball track conduit and the accumulator or receiver so the heat is used as gas or steam pre-heating before combustion or the compression step. 
     In operation, a single unit, or a plurality of these ball/track units, can deliver hot exhaust gas into an accumulator or receiver as described that has a ceramic lining in the form of a torus tube functioning as a high pressure vessel capable of handling gases with temperatures and pressures as high as 3,000 degrees F. and 600 psia. The torus tube geometry favors the heat expansion problems. 
     The higher pressure Engine/Compressor form in which the piston function precedes the ball drive would be suited for refinery needs where lower volume and very high pressures are required as for example in the several stages for the compression of Hydrogen. 
     It is desirable in this unit to incorporate the drive device and compression apparatus inside the same structural body as noted in the Summary. This is accomplished in part with the incorporation of the Rotating Valving Cylinder form as the means for control in the apparatus. This compact apparatus affords a way to minimize unit cost and provide a smaller apparatus that more efficiently controls the losses of heat energy normally associated with separate engines coupled with compressors, while at once providing low-cost multiple unit installations that make for easier maintenance and down-time loss as opposed to taking a primary large unit out of service for refit. A small unit that is one of a dozen in operation can be shut down without loss of service. 
     This method and the apparatus forms provide the option of using Natural Gas combustion, or high pressure natural gas expansion as from a gas well to move pistons apart as in the Engine Compressor with elimination of the first stage ball drive. Such high pressure can also be applied in the Toroidal Turbine so it can perform as a prime mover for driving conventional pumping means as in pipeline situations. Very high pressure well gas can be taken off the well and let down between the pistons of the Engine Compressor or introduced to the ball drive of the Toroidal Turbine with endothermic advantage for power generation and afterward exhausted to a tank separator for removal of butane and other liquids so the Natural Gas can be taken off at usable temperatures for delivery to the pipeline. The refrigeration generated can be employed to cool the gas to pipeline levels. 
     The Engine/Compressor of this invention is designed to make maximum use of a continuous flow of hot gases from combustion, or modulated ignition timed to coincide with the pulsed introduction of an ideal gas/air mix to a combustion chamber closed by a rotary valve as a ball projectile is clamped at the opening or entrance of a track conduit, along which the ball is propelled by combustion release to overcome the clamp. The moving ball compresses the residual exhaust gas standing in the tube that remains from the prior ball firing. At the ball termination, latch point or sprage block the gas ahead is shunted to a receiver as a like plurality of successive ball excursions contribute a pressure accumulation suited to release for use as a first or second stage pressure depending upon the application. 
     The travelling ball passes a sensor point near the end of its circuit that indicates the end of the ball excursion where it is braked by the compressed gas ahead so that it has a controlled impact against a standing socket or vacant space between the &#34;latches&#34; of the geneva gear. The geneva or stepping gear position is generally at right angles to the ball travel, but a curvature in the path at the end of the ball travel causes it to impact angularly against another ball standing in a geneva socket. The force vector at an approximate 45° to the geneva face or axis causes it to turn one step to moves off a detent retention, which same impact moves a second ball held at a distant point around the geneva&#39;s circumference to move into the clamped firing position. As the gas burst occurs and the ball ejects, it passes another sensor point as it begins its circuit. This ball operational cycle provides the first stage compression of the gas in one Engine/Compressor configuration of this invention and, as the balls pass the sensor points, the two pulses and the interval between comprise the travel time used for control of the ignition timing and fuel input, but equally important is the stepped movement of the geneva gear as provided by the balls&#39; impact force. The rotation of that geneva gear is an integral part of the a holed cylinder body that encloses the piston. The cylinder&#39;s rotation by this means provides the porting or &#34;valving&#34; for timing introduction of the gas input and output release to the pistons inside the cylinder body. The injection of fuel gas to the combustion chamber and to any other requirements are accomplished by simply varying the number, positions and sizes of these ports in the cylinder body as they are step-turned and related to aligned ports in the enclosing outer static stator structure holding the cylinder. Torus shaped manifolds encircle the piston cylinder walls internally and serve these ports. The stator has like manifolds internally in its walls with ports that align with those of the pistons ports to serve the input and output needs of this engine/compressor unit. 
     The gas in the first stage receiver is compressed by a specific plurality of ball excursions and is delivered to a position between two pistons, forcing them apart as this introduced compressed hot exhaust gas expands in this space to create an endothermic or cooling condition in this exhaust gas. The pistons are moved apart by this means against the product steam or gas that has been introduced on their opposite sides to be compressed. The enclosing cylinder rotates independently of this piston action in response to the ball impacts. As the pistons move against this product gas space to compress it, they also close against open compression springs. The product gas or steam is exhausted over pop-off valves, and the pressure of the hot exhaust gas expanding behind the pistons is released as the pistons move past ports through which all of this driving pressure is exhausted. The springs return the pistons and suck in new product gas to this space through ports that are also in the cylinder and stator walls and are timed to open as the cylinder tube is step-rotated by the geneva to those positions. This rotary cylinder means and porting alignment eliminates complex valving and valve mechanisms for actuation. 
     Before full release, a portion of the exhausted gases that have driven the pistons is moved into a manifold area inside the walls of the cylinder and out a plurality of small perforations in the outer wall periphery to provide for the escape of nucleate steam bubble pressure as a product of the water that is a part of this exhaust gas. These bubbles form on the small openings and provide the support for the rotation of the cylinder as they expand, burst and are replaced. In a like manner small openings in the periphery of the pistons function in the same way. These functions are described in detail in my co-pending U.S. patent application Ser. No. 08/653,967. 
     In a related function, the tubular form in which the balls travel has a cross-sectional configuraton in which at least one-half of the tube&#39;s inside diameter is a suitable fit to facilitate rolling of the ball while at least half or more of the remainder is very slightly larger for clearance of the ball diameter, which surface obviously moves in opposition to this half of the tube as it rolls. This fit and space provides the ability for the ball to roll freely if gravity or centrifugal force is used to cause the ball to rest or roll in the fitted surface, otherwise it would fall away and be too loose. To overcome this problem and to assure the position of the ball in transit, a means is provided to create a nucleate bubble input into this larger diameter space. This also provides the means to permit free rolling and the sealing of the space between the ball&#39;s surface and that of the larger space diameter in the tubular conduit. This is done with use of a finite slit opening that runs most of the length of the tube. This is placed in the cross-sectional center of the larger radius fit so this area and space between the conduit wall and the ball&#39;s line contact afford an area for the nucleate bubbles to squeeze past in the passage of the ball as it rolls. The slit is supplied with input by a small manifold tubular form that runs parallel on the inner side of the track to service the slit and the larger tube diameter area and form. The slit is between the two in a common structure. Functionally pressure behind the ball moves into this slit and out of the slit ahead of the ball travels. This occurs because the pressure is much less ahead of the ball as its travel begins, and the nucleate bubbles bead up along the slit in the path of the approaching ball to be swept under the ball and through this larger space around the ball&#39;s line contact as its high speed creates a momentary laminar layer of ball-like bubbles for it to roll over as it swings around this curve in its travel. The pressure in this space is greater than the pressure ahead in the compression area. At the calculated point in the track where the gas pressure in front of the ball begins to build to equalization of the pressure behind, the slit is terminated. 
     The geneva gear step rotation provided by the ball&#39;s impact turns the cylinder body inside a sealed laminar space that is itself filled with explosively expanding steam bubbles that escape through pressure limiting orifice openings at the cylinder ends and around its periphery. This support eliminates the need for bearings or seals as well as lubrication, affording ability for the cylinder to move in its step-turning at 10 to 20 rpm without friction on this mass of nucleate bubbles that are constantly forming, expanding and escaping. The ability to dispense with bearings and seals in this apparatus is of great benefit because at the high temperatures, lubrication of normal bearings that would be a particular problem in the carbonization of such lubricants. This elimination greatly simplifies service and maintenance. 
     If a cycle comprises three-balls moving in the circuit, each such group would for example supply the pressure for one piston excursion of the second stage. The accumulated pressure of the three-ball excursions provides the force for example one stroke each second and, if there are eighteen step provisions in the tooth-like sockets of the geneva, it would then rotate 1/6 of a revolution per second or at a speed of 20 rpm. By providing six hole positions in the cylinder tube for alignment with six in the stator input and output for the piston functions, one stroke of the piston pair can be provided each second. In this way 11 balls work the system. One is in transit in the loop and the remaining 10 are standing and filling half of the geneva sockets in the circumference. 
     Each ball excursion moves the cylinder one step. The first impact and geneva position step opens ports to introduce product gas for compression. The second ball impact gates the input of hot exhaust gas to move the pistons apart, and the third ball impact opens ports for release of the driving gas so the spring return can suck in product gas for compression as the first ball of the next three-cycle program impacts to open the product gas input ports. A series of notch-like cuts in the outer wall of the stepping cylinder provides intermittent openings to adjoining gas pipettes meeting at these notches so the gas input for ignition can be time-pulse synchronized with use of the same stepping cylinder function. 
     The Tower Compressor 
     A third form of this invention is a relatively simple Tower Compressor that makes use of the nucleate bubble piston support on a large piston and in a long cylinder form that can be used to compress low pressure steam as it comes off the turbines as in an electrical power plant. This steam is compressed to a high pressure and temperature without return to the boiler. After compression it can be reintroduced to the turbine and, when expelled from the turbine, does not require passage through condensers, but goes directly back to recompression in the Tower Compressor with some steam makeup from a low horsepower and low pressure/temperature boiler. 
     With the use of a plurality of Tower/Compressors and the gas combustion units of this invention, several in tandem can provide as much compression volume as may be needed to compress vapor to saturated steam pressures and temperature just below that of superheat, or as close to 1,000 psia and 544 degrees F. as possible in substitution for boiler steam generation and use with a turbine drive, or the Tower Compressor units can be used in successive stages with the last unit making a pulse transfer of the steam directly into a boiler. This could be done to recover surplus low pressure steam and prevent the energy loss if it were simply dropped to the water phase. 
     In a power plant steam compression situation the natural gas used for combustion in a Tower Compressor is a fuel at the lowest possible rate and compares favorably to steam produced with natural gas using conventional boiler means. 
     The Toroidal Turbine 
     A fourth application is the method of combining a plurality of Tower Steam Compression systems with a Toroidal Ball Turbine in which a toroidal coil of tubing-like conduit or an equivalent toroidal path is machined inside a large stator block to provide entry and exit from a heavy walled cylinder-like stator center element. Each turn of each helical loop provides the balls in that loop with connection to a continuous toroidal path so they can be simultaneously driven by steam pressure, or a series of gas combustion sources to deliver pressure to each loop of this continuous circuit so the ball in each loop can be propelled along the static grooves of a stator bore, while rolling against the intersection engagement of the like half-round curved grooves in the outer diameter of a rotor in the stator. This pressure applied against the ball&#39;s surface as it rolls against the engagement point between the two intersecting grooves forces the rotor to turn in the static stator. 
     A large plurality of loops in this toroidal conduit form provide for a plurality of ball projectiles that are all driven at once through all of the stator grooves to engage all of a like plurality of rotor grooves as they align to create a multiplication of power for continuous input to this rotational effort as successive waves of balls follow the stator&#39;s expelling of the first wave. The driving steam pressure exhausts at the rotor end through ports in the grooves that the balls pass over. The balls have enough velocity to continue through the loop to impact the ball stack at a latch point or sprage block in the loop from which they are in turn ejected into the pressure stream to again re-enter a groove pair in the stator bore and rotor shaft. The plurality of balls at the loop end create a seal in the conduit as they stand behind the one held in a latch ready for launching into the pressure stream. The latch or sharp turns at the stack-up with a sprag pin can prevents pressure backing the balls into the conduit when appled against the ball being launched. 
     Exhaust steam moves from the rotor groove exhaust ports through a rotary seal serving a static exhaust tube and some is bypassed to the nucleate bubble slits in the grooves of the rotor. The major flow ends in pressure coils that wrap the Tower Compressor Exhaust Stack to bring up temperature and pressure at this stage after which it is allowed to endothermically expands in larger volume steam coils around the body of the Tower Compressor Cylinder that serves to control the cylinder temperature.

     An object of this invention is to compress steam to restore heat and pressure to this spent gas without the use of a boiler or condenser in the cycle by applying the combustion of natural gas as the driving means for a free piston apparatus in the compression function. 
     An object of this invention is to compress steam to restore heat and pressure to this spent gas without the use of a boiler or condenser in the cycle by the use of volumes of low pressure steam with the piston size pressure amplification free piston means of this invention as the drive for this compression procedure. 
     An object of this invention is to compress steam with a free piston apparatus in a vertical or inclined cylinder at the bottom end of which a breech-type recoil mounted chamber is pulse-controlled to direct natural gas combustion pressure into the breech and cylinder barrel to drive a free nucleate bubble supported piston upward against a coil spring return to drive pressurized gas over a pop-off valve at high pressure and temperature, which piston&#39;s upward travel has relieved the pressure behind it to open a delayed spring closing the exhaust port so the combustion gas exhaust can escape, and the piston can be dropped by gravity and the low pressure product steam input at the cylinder top, which piston drop closes the spring valve port so combustion firing of gas input provides the drive to repeat the compression stroke. 
     An object of this invention is for a free piston compression apparatus to be driven with Natural Gas combustion means in which the spent steam from a generator turbine or the like is returned to the said free piston apparatus; first through a coil surrounding the 1,500 degrees F. exhaust tube for the compression gas which raises the spent steam pressure and temperature so; secondly it can be injected into a coil enclosing the free piston cylinder which reaches high temperatures created by the steam compression function and which steam injection to this larger coil provides expansion and an endothermic temperature reaction to control the temperature of this cylinder. 
     An object of this invention is to compress steam with a free piston apparatus in a vertical or inclined cylinder at the bottom end of which a breech-type recoil mounted chamber is pulse-controlled to direct natural gas combustion pressure into the breech and cylinder barrel to drive a free piston, and which recoil function is harnessed with a plurality of compound piston cylinder assemblies to provide for the compression of air needed in the natural gas/air mix for combustion and at once pump the water input to attemperation mist apparatus to inject water make-up to the coils on the compression cylinder. 
     An object of this invention is to use a very low pressure and temperature boiler in the range of 25 to 50 horsepower to replace the very large boilers in a normal 50 megawatt electrical generation system as the start means to make the initial warm-up and operating steam to start the free piston compression apparatus. 
     It is an object of this invention to employ a hollow titanium ball with a high finished hard chrome surface and with small vent holes in the range of 0.075&#34; to 0.100&#34; wall for maintaining pressure equalization as the driven ball projectile of this invention. 
     It is an object of this invention to use a valving means in which a large wire size compression spring with a square wire form is finished by grinding all the surfaces to close matching finishes so, when closed, the spring presents a series of virtually sealed surfaces between the coils so that upon closure when closely fitted into cylinder walls with a port, therein the closed coils close the port and, when extended open the port to the cylinder interior. 
     It is an object of this invention that when using the square section ground spring as a port closing valving means, its action is delayed in opening from the closed position by a second spring that is a flat cross-section 1/8 inch to 1/4 inch leaf type that is of a width 11/2 inches to 3 inches and wound upon itself with one turn and thereafter ground on the ends, I.D. and O.D to a good finish and, so all dimensions exhibit close tolerances in wall thickness, which spring application is to fit closely within the respective cylinder I.D. so it is seated against the top of the square section bottom coil spring. 
     It is an object of this invention that the said flat cross-section spring as described above fits so closely to the cylinder wall that the square spring opened can only slowly overcome this friction rather than simply snap open as the piston&#39;s downward pressure is relieved. 
     It is an object of this invention that the said flat cross-section spring as described above fits so closely to the cylinder wall that the square spring when opened can only slowly overcome the fit because the explosive pressure against the said flat spring&#39;s inside surface, as the pressure impacts the piston&#39;s bottom, causes the flat spring&#39;s single turn to unwind slightly, making the spring&#39;s diameter larger inside the cylinder, which grip holds until the pressure drops, so the square section spring can maintain the port closure and allow the piston to move almost to the top of the cylinder before this exhaust port opens. 
     It is an object of this invention to use a plurality of projectile balls that are held within a continuous toroidal looping helix series of tubular form turns that are arranged so each turn, loop or helix loop enters and exits and a mounted stator on the inside bore of which straight grooves run the stator length having a half-round fit to the projectile balls, the other half of which fit like grooves in a rotor that is a close rotation fit inside the stator bore, but which grooves have a lead angle so each groove makes a single turn around the rotor surface in one revolution, so a series of balls, one in each groove of the stator and rotor as driven by pressurized gases, are forced to pass along the straight rigidly-held stator groove so the rotor is forced to turn with the sum of the pressured applied to all the balls simultaneously in the transmission of pressure energy to rotary energy.

     DETAILED DESCRIPTION OF THE INVENTION 
     FIG. 1 In this schematic illustration the introduction of natural gas and a combustion chamber is ignored. What is shown is the movement of a projectile ball at positions l8, 19 and 20 in a diminishing curve tubular enclosure 30 and a piston 3 and 4 of two sizes that engage a cylinder configuration 29 that is turned by a geneva gear 23 ball latching apparatus 36 and that serves to catch and eject the balls from the firing positioning 7 showing the ball 15. The cylinder body 1 is forced to move one step in rotation by the gas pressure driving the ball 15a on its return at 37 impacting the stepping geneva 23. This rotation of the cylinder 1 aligns porting 8, 9, 11, 12 and 13 between it and the stator 2 to admit and expel gases. The sealed stator enclosure 2 holds the cylinder 1 without bearings or rotary seals because the cylinder 1 is supported in the stator 2 bore by an array of perforations 28 around the sides and ends of the cylinder walls from which nucleate steam bubbles are expelled so this element turns freely as stepped by the geneva 23. (Wall manifolds that supply this steam is not shown.) The Large size piston 3 in the large portion of the cylinder 27 has a like perforated steam-fed area on its surface 14 that holds the piston on a like laminar nucleate bubble steam layer spaced away from the cylinder walls. An extension of this piston at 4 drives into a smaller cylindrical space 7 that serves to drive the ball 15 out of the latch 36 (shown simply as a spring representation here) into the diminishing tube conduit ball path 30 at ball position 18. Pressure for driving this apparatus enters the stator at 8 and 9 and through porting in the geneva rotated cylinder body 29 which ports are timed to align for this input after which they are closed by the rotation of the body 29. The port timing function is not shown here but is largely a function of port positioning. Ports 10, 12 and 13 are opened as needed for control of the piston&#39;s drive, exhaust and return stroke. Low pressure steam is introduced into the master cylinder 27 at port 10 which is then closed by the cylinder turn. The piston is driven forward by high pressure steam delivered at 8 and 9 as these ports are opened. The low pressure steam moves through ports 12 and 13 to point 17 as these open. (In some cases these ports are slots in the stator of some length to accommodate longer times for inputs as in the case of 12 and 13.) These provide for introduction of a low pressure steam volume ahead of the ball 15 before it bursts out of the retention 36 as driven by the higher pressure of piston 4 in the small cylinder 7. As the small piston extension 4 closes the opening of the small cylinder 7 further steam cannot enter at its opening border 5 and 6. There is some momentary high compression as the large piston 3 passes ports 12 and 13 through which it has driven the maximum input of steam behind the ball 15 which is now at position 18. As the large piston 3 closes the final cylinder space of 27 the compression provides a momentary back pressure &#34;bounce&#34; for the return stroke as the piston 3 moves back to its starting position. The ball 15 runs through positions 18, 19 and 20 in a diminishing diameter or spiral to reach its entering point at 21. The reduction of ball path diameter 30 to 21 causes some acceleration of the ball to offset the dropping drive pressure and the increasing pressure ahead of the ball at the end of its excursion 21 and before it finally reaches the latching position 37 in the geneva 23. The rotational direction of the geneva is shown at 24. As the ball has latched at 37 it has driven the gas ahead of it over the pop-off valve at 26 and into a receiver at 25 from which it is delivered to points of use. 
     FIG. 2 is an open schematic of a tubular form ball pathway 18 used as the conduit for the ball excursion of this invention in which the ball position 19 is shown to correlate with the ball position 19 in the FIG. 1 illustration. The outer half of the tube 18 radius 31 fits the ball while the inner radius half 32 is slightly larger in diameter so the ball can roll freely on the fitted diameter 31 and be clear of diameter 32. 
     FIG. 3 is a sectional view of the spring activated collet-like clamping jaws of a retention device for latching the balls in the geneva gear stations so the spring tension can be overcome by pressure on the ball to expel it from this position. The jaws 36 fit and turn around the ball 15 diameter with a knife edge 42 on each jaw, the sharp edge of which permits this curving fit around the ball diameter. This edge 42 also extends to encircle the cross-sectional diameter of the body circumference of a precise metal torus ring 40 in which the ball 15 comes to rest when latched. This ring has a very close I.D. running fit for a ball of class RC3 or equal. This metal torus ring 40 constitutes the &#34;sealing&#34; surface against and around the ball while in the geneva latching position with the spring pocket FIG. 5, 39, as a part of another annular ring assembly that has a static fit to the torus ring 40 and in turn is held in the body of the geneva in a like manner so the area is sealed by the fit between the torus 40 and the ball 15 for minimal bypass slip. The jaws are shown in an open position 36 and closed 37. When opened the jaws exhibit some spaces in the adjoining interval and springs 41 maintain these annular positions in relation to one another. The jaws are on the down stream side of the sealing torus ring 40. 
     FIG. 4 is an illustration in cut-away showing two of the balls at rest in the sockets 23a of the geneva gear 23. Only two latches are shown in the interest of clarity, however a jaw latch 36 is located at each socket position. A jaw 36 is shown in the closed position with a ball preparatory to firing. Another jaw 36 is shown holding a ball at position 21 having just received the ball. The bore of the small cylinder of FIG. 1 is shown at 7. 
     FIG. 5 This is a cross-sectional side view. The geneva housing is shown at 23 and the open jaws 36 are closed 37. The ball 15 is seated on its exact maximum diameter center in the torus sealing ring 40 and held here by the accurate and precision placement of jaws 37 that are in the closed position. The individual jaw springs 39 are shown in the position they assume when the jaws are closed. 
     FIG. 6 A cross-sectional schematic drawing of the engine/compressor of this invention in which two stages perform the compression work. The first stage makes use of a ball projectile driven through a tubular conduit that compresses the hot exhaust gases used in propelling the pistons of the second stage in which a piston pair in a cylinder receive the hot exhaust gas inserted between them so they are driven apart to compress a product gas that is on the outer or opposite ends of the pistons space 76. A gas flame combustion center 51 receives gas input from pipe 53 and supercharged air input pulsed by rotary valve 54 as this valve receives its air delivered from a heating coil 55 wrapped around the combustion chamber 51. The air input is pulse introduced to the chamber and mixed with a gas from pipe 50 just before reaching the combustion point at 51. The gas explosive burst at 52 expands in the tube breech space 56 to flow beyond the ball stop 39 in space 58. The building pressure behind ball 15 as held in latch 36 of the geneva 23 while the ball 21, 180° from the ball 15 that has just seated itself in an open latch 37 creates a shock of its impact that adds physical force to the building pressure to dislodge the ball 15. It bursts into track 30 which is the opening of the conduit path 18, 19 and 20. The ball 15 is then driven by the gas flow and expansion behind it through these positions finally ending at 21 after forcing the exhaust gas into conduit 22 and beyond across the air impeller 62. Impeller 62 drives a blower 63 delivering air to the combustion chamber jacket heating coil 55 along pipe 53 for input to pulse valve 54. The exhaust gas after driving the impeller 62 has lost velocity but not pressure which accumulates in the chamber 65 past a check valve not shown. This chamber 65 encircles the center cylinder assembly 61 that holds two pistons of the nucleate bubble support type 67 and 68. When the porting in the cylinder wall 61 aligns with that in the stator that connects to reservoir 65 the pressurized exhaust gas moves into the space between the pistons 67 and 68 at 66. This forces the two pistons apart closing the spaces 76 and compressing springs 71 to compress the product steam or gas that has previously been sucked into this space through ports from manifolds 74 fed by prior steam passage to port 72 and through a combustion chamber heat exchanger encircling area 52 for preheating. The compressed steam of space 76 is driven out over pop-off valves at 26 to the high pressure receiver at 25. As the pistons 66 and 67 reach full compression in cylinder 61 and space 76 a plurality of ports 80 are opened to finally release the fully spent exhaust gases into the cylinder wall manifolds at 81 and out vents at 82. The manifolds 81 have some low pressure steam injection (not shown) so they can service the perforated cylinder support surfaces as illustrated at 70. These are provided on much of the cylinder surface in bands between porting orifices. The perforations 69 of the piston like those of 70 on the cylinder wall serve to propagate the nucleate bubble generation that is the support for the cylinder and the piston in the cylinder. While not shown the ends of the cylinder have similar perforated surfaces that connect to the wall manifolds to maintain the cylinder center position in the enclosing jacket. The excursion of the first stage ball passing along the tubular track that, as shown in FIG. 7, has two diameter dimensions, half at 31 fitted to the ball and half of the cross-section at 32 slightly larger than the ball. This permits the introduction of bubbles along a slit that separates this large tube track from a small parallel tube 34 that is a manifold for exhaust gas input that is not shown here. It is important for the timing of ignition and gas input that the position of the balls be known at the start of the excursion and at the end. A pair of quartz windows mounted in a Kovar sleeve as shown 83 and 84 can serve to pass the light of a laser 85 and 86 from a remote source through a bore to an annular opening in the stator that fitted with sensors as at 87. The ball passage provides an interruption of the laser light at the beginning and end of the ball&#39;s trip which would be used to integrate with all the other timing so the operation could be properly synchronized. The laser light would penetrate exhaust gas in this narrow passage and also penetrate high temperature steam that is essentially invisible. The use of the laser and quartz window means is described in my Provisional Application No. 60/019153. 
     FIG. 7 is a cross-section of the tube 30 showing the ball 15 in the tube with the size in diameter difference at 31 and 32, the slit 38 that forms the bubbles 90 as they accumulate in the space between the ball and the large diameter portion of the tube 32 as the ball travel sweeps them up as they are generated from the small tubular manifold at 34. 
     FIG. 8 is a side view or schematic of the ball 15 in the tubular track 30 illustrating the ball&#39;s rolling direction at 94 and 95. The ball rolls against the fitted surface of 31 rolling as in 94 and 95 imparting the direction shown at arrow 93 and the clearance of the ball at 96 in the space of the other larger diameter half part of the tube&#39;s cross-section 32 that is filled with nucleate bubbles as accumulated beneath the ball at 90 as delivered through the slit 38 from the tube manifold at 34 so they move into the manifold from the pressure behind the ball at 91 and exit ahead of the ball back into the manifold through the same slit 38 as seen at 92.

     FIG. 10 A plane view of the air blower impeller 63 of FIG. 6. 
     FIG. 11 A cross-section and schematic side view of the steam compressor that serves the Toroidal Turbine Prime Mover. This unit is driven by Natural Gas compression that is shown entering the unit through pipe 100 and valve 101 jetting into a compressed air stream mixing point at 103. The compressed air is controlled by a like valve 102 to that of the gas valve and both are high speed rotary type stepping motors controlled and synchronized to the ignition 152 and the rotary pulse valve 105 that inputs the air gas mix to the combustion chamber 151. The gas explosion of some force here is handled with a recoil mechanism 104 that in turn is used to drive a plurality of double acting pumps 107 and 108 to compress air as delivered through pipe 109 for the reservoir receiver at 110 and to pressurize the water with double-acting pump 108 delivered through 111 for the attemperation unit 112 that serves as a feedwater input for the master preheating steam coils 140. The gas explosion propels the piston 113 to position 114 moving through the long vertical cylinder 143 to move the gas 150 within this space. The piston at 114 has compressed the steam content of the cylinder 150 previously sucked in by the same piston&#39;s return stroke after it has rebounded off compression spring 115 and driven the compressed steam over the pop-off valve at 117 and through pipe 118 and 119, for use as high pressure steam. A check valve 116 in the input steam line prevents this pressure from flooding the steam return. At the top of its stroke as shown at 114 the square section bottom spring 146 has overcome its pressure activated friction retainer 145 and opened an exhaust valve 147 to the exhaust stack 148 and as the piston drops to the position 113 it drives out the hot exhaust gases. The 105 pulse valves open momentarily so the compressed air from the opening of valve 102 can be blown through the combustion chamber to clear it completely of residual burned gases. The piston completes its downward fall to 113 pushing the friction retainer 145 downward to close fully the coils of the square section precision ground spring 146 that at once fully closes the exhaust port 147. The system is ready for a new gas explosion. When this explosion burst does occur it first provides pressure on the friction retainer 145 expanding it against the cylinder wall to hold the square section spring 146 at its position momentarily so the exhaust port 147 remains closed as the piston moves to the top and position 114. The exhaust steam 134 from the Toroidal Turbine Prime Mover is taken into the compressor system coil at 135. This coil 138 either encloses or is inside the exhaust stack to take up the exhaust heat that can be in the order of 1,500 degrees F. This raises the return steam pressure and temperature after which it is transferred to the larger coil around the compression cylinder at 139 where it expands with an endothermic reaction to help in controlling the temperature of this long compression cylinder. After moving through the coil 140 for this purpose its pressure is delivered through pipe 141 in direction 142 over the check valve 116 to the suction of the piston dropping from the 114 position that fills the cylinder with steam for the next explosive burst of gas combustion.

     FIG. 13 An enlarged view of the standard attemperation unit 112 with the water pipe input at 111. 
     FIG. 14 A cut-away illustration of the square wire spring that is ground on all its surfaces with special tooling to fit when fully compressed with all the coils seated so it will serve to seal the port in the cylinder wall, together with the friction retention spring that delays the opening of the square compression spring after its full compression and because of its fit against the cylinder wall that is a result of gas explosion pressure momentarily applied. The square section spring 146 in the cylinder walls 143 and the friction retainer spring 145 set so the ground finished and fitted spring coils close the port 147. 
     FIG. 15 A small start-up boiler 137 for steam input to the compressor for the start of its operation with steam deliver 134 after which it is shut down. This can be compared to the compressed air unit used for the start-up of a diesel engine. 
     FIG. 16 This schematic sketch is an illustration showing the application of the steam compression system of FIG. 11 in connection with steam supply for the turbine of this invention. Here a small boiler 137 supplies startup and standby steam requirements at low pressure and temperature for this turbine. To achieve the steam volumes required a series of these compressor units work in synchronization. These are driven by natural gas as described earlier. The piping of this illustration shows the compressor units located typically in a series like 143. These are supplied from a gas main 100 delivered from line 160 to the ignition systems 151, a,b,c,d,e,f and g for the piston drives. Low pressure steam is delivered typically to the cylinder heads at 143 from steam riser 139 delivered from tank 135. This is the return steam from the turbine of FIG. 18. Compressed steam is typically taken off the cylinder heads at 143 through a series to a relief valve 117 and run along line 1 18 to a downcomer serving a coil 140 in a tank 138. Tank 138 also receives combustion exhaust gas from the combustion end of the cylinders 147 and passed as a group to an exhaust manifold 157 topped by steam pressure from line 158 metered to deliver a moderate downstream pressure to 157 aiding in driving gases to pass these over the heat exchange coil 140 in tank 138 to release through stack 148. This serves to extract heat from the 1,500° F. temperature of the natural gas combustion exhaust gases and provide additional heat to the compressed steam that subsequently is delivered to the turbine through line 120/121. Pipe 159 is a steam blowdown. A steam loop 156 is provided to service the compressor in startup and for makeup of steam loss. The steam return is 155. Input of this steam is supplied through the suction tank 135 that is normally supplied by a turbine as in FIG. 18 through line 119/134, but these can be bypassed by opening valve 152 to service the compressors with low temperature pressure steam from the boiler 137 and steam loop 156 through line 153 to tank 135 and manifold 139 that delivers through check valves to each of the compressors. 
     FIG. 17 This sketch of the Titanium or Inconel alloy ball of the Toroidal Turbine 15 shows the thin wall at 144 and the venting ports at 149. 
     FIG. 18 This is a cross-sectional illustration of the Toroidal Turbine Prime Mover driven by the compressed steam of the apparatus described in FIG. 11. Here high pressure steam and is delivered to a plurality of coils or a toroidal series of helix turns that open into and exit from a fixed stator that encloses grooved pathways that comprise two half-round grooves, one straight or optionally curved in the stator bore I.D. and the other curved oppositely on a closely fitted rotor shaft O.D. so the two coincide at an intersection to enclose and support a ball. This intersection moves to provide a channel for the ball as the ball causes rotation of the rotor. The ball, driven by compressed steam, enters this groove pair at the intersection where the rotor and stator paths cross to provide a round opening for the ball&#39;s entrance. The ball is then driven along the stator groove and held in its course to force the curving rotor groove, enclosing the ball&#39;s other half, to turn as the ball rolls from one end of the stator and the rotor to the other. The toroidal path for the balls is one continuous circuit and the balls simultaneously arrive at the point where each single helix turn of the toroid enters the stator. Thirty stator and rotor passages provide for thirty balls driven across the stator and the rotor so the pressure applied is the sum of these. 500 psia on one ball is 15,000 psia on the lot causing the rotor to turn on its axis. Steam is exhausted from ports in the grooves at the rotor ends through a rotary seal and released for recompression. The stator is shown at 122 and the rotor at 123. Pressure is introduced continuously at 120 as applied to each helix input. 121 represents another input for another helix loop. A ball 15 at conduit position 125 is just entering the grooves and will progress across to 127 in a straight path to follow the stator groove. From there the ball 15 at conduit position 128 moves around the helical loop 129 to stack with other balls at the latch 36 for injection by ball impact into the steam stream to re-enter the stator at the next parallel groove with its own discrete steam pressure input behind it. The ball stack and latch (not shown here) prevent steam backup. The grooves in the rotor are shown at 128 and the rotational direction at 124. The exhausted steam output moves through the ports at 130 to the shaft center bore at 131 and out through the shaft sides through a rotary seal to piping 132 and 133. The spent steam output of 130 moves through pipe 119 to input 134 to compressor exhaust stack preheater coil 140 of the steam compressor. 
     FIG. 19 A cross-sectional illustration of the piston of this invention shown in a position inside a cut-a-way cylinder 162 with the perforated piston surface that is a generic feature of the several different apparatus forms in which the piston is numbered variously as 3, 67,68,113,114 and 128. The perforations range in diameter from 0.020 inches to 0.075 inches and are prepared in a thin sheet metal stock inset into a cylindrical body 164 and 163. The ends of the piston 165 have a slight taper of 3 to 7 degrees that serves to provide a nozzle-like effect as the bubbles formed on the perforations stream off the trailing end as the piston moves. The laminar gap 167 between the piston and the cylinder walls 162 ranges from 4 to 10 one thousandths of an inch on a side. 
     FIG. 20 This is a cross-sectional illustration of the edge of the perforated sheet and the perforations 168. The cylinder wall is shown 162 and the gap or laminar space 167 is shown between this wall and the piston perforated surface 168. Supporting the perforated wrap of sheet metal is a fine thread 166 cut in the piston surface, the open thread spacing of which serves to allow a flow of steam of liquid to move around the piston&#39;s circumference and into the small ports uniformly. This threaded area is relieved longitudinally at intervals so porting from center opening into these reliefs can serve the perforations from the center of the piston. 
     FIG. 21 A three-dimensional view of a representative piston 128 in which the piston is mounted on a shaft 123. All of the pistons used in this procedure have a similar internal manifold arrangement. Steam or liquid is supplied from the piston end 169 and moves to a center bore 170 and beyond to lateral porting 171 and 172. This is followed by a second layer of porting 173 and 174 that is shown as a clear opening and is a longitudinal cut made across the threaded outer diameter support surface 166 of the piston that holds the layer of perforated sheet metal 168. 
     FIG. 22 A cross-sectional illustration of the dual track system of the toroidal turbine in which a rotor 126 is supported on a shaft 123 in turn supported on bearings 179 inside a case 173 that also encloses one fixed member 175 encircling the rotor 126 and one counter-rotating shell member 178 enclosing the 175 shell. The shell 175 has grooves in both the inner and outer surface while the outer shell 178 has grooves only on the inner surface. The ball 15 is driven along the interfacing grooves 176 of rotor 126 and the inner surface of inner shell 175. In this illustration both grooves curve to oppose each other and provide the intersection engagement of the ball. As the ball completes its passage that causes the rotation of the rotor 126 as it exits this engagement at 202 it passes over a gas escape grating 180 so the driving pressure can exhaust to manifold 183. The ball then moves to the engagement at 203 between the shell members 175 and 178. Inner shell 175 is shown with a straight groove 204 in its outer wall and outer shell 178 with a curved groove 205. This is the return path of the ball that brings it back to the inlet or starting position. The straight groove in the outer wall of shell 175 can optionally be curved to provide a driving force of higher speed or provide other desirable variations. A planetary gear system 181 driven by the rotor shaft 123 turns fixed position idler gears 184 inside a follower ring gear 206 in a common gearing form. The idler gear 184 turns on a shaft 207 that is mounted on the end of the inner shell member 175 at 208 providing a rotation counter to that of the rotor. These shafts and the attachment of the shell 175 to the case 173 employs a mounting arrangement extending between the drive and the ring gears. This gearing arrangement provides a means to drive the return path of the balls in an opposite direction using any opposing groove angles that are appropriate so there is no dependence upon a portion of the gas exhaust or gravity for completion of the circuit to the starting point. Appropriate seals 209 are provided in all rotating members and the taper roller bearings 179 serve primarily as thrust elements on both ends of the supporting shaft 123. The point 210 is the location of the &#34;choke point&#34; or the stack up of balls as illustrated and detailed in FIG. 23 at 210 which is not shown in this drawing. This is essential in providing the sealing means of the ball&#39;s fit against the passage walls. The balls are blocked from reversing direction by the pressure applied to drive the nearby working ball 15 through the rotor and stator grooves. This reversal of direction is prevented by the tortuous curvature in the passage at this point 210 and the setting of the sprag pin adjustment 188. 
     FIGS. 23 to 26 Assembly drawings for the apparatus are shown here in FIG. 23 and sections 24--24, 25--25 and 26--26 to illustrate the detailed features of the rotor and stator in a unit comprising 16 external rotor grooves and inside of the stator with 8 internal grooves. Cross-hatching lines have been omitted for clarity. The stator 122 is stationary and a part of the body. The rotor 126 turns in response to the drive of the representative ball 15. The rotor 126 is shown with a representative curved rotor groove 186. The straight stator groove is 196. The exhaust port is in the rotor 130 exiting through porting in the shaft 131. Pressure is introduced through the port 203 and moves against the ball 15 driving it past the choke point 210. A sprag set screw 188 provides adjustment restricting the ball passage in the turn at the choke point to prevent pressure backup. A gas release needle valve 195 adjusts to release gas leakage past the balls at the choke point 210 and prevent pressure accumulation in channel 189. The ball 15 traverses the path between the grooves 186 and 196 to reach an exiting point 205 where it turns in a tube loop bend 193 to 194 after which it traces a return by gravity along path 189 to the stack-up at the choke point 210. The shaft 123 is supported in bearings at 190. 
     FIG. 24 A sectional view taken through the fragmented section line 24--24 of FIG. 23 showing a top view of that assembly 191 to illustrate the bent tube configuration 192 (as viewed from the side) providing the reversal of ball direction and the continuity of the circuit in a plurality of tube bends 193 serving the outlet 205 and the input 194 of FIG. 23. 
     FIG. 25. This fragmented section 25--25 shows the grooves in the rotor 126 at 186 and the stator at 196 with the return path in the stator wall at 194. The gap between stator and rotor is shown at 197. 
     FIG. 26 A fragmented sectional view 26--26 shows the rotor 126 has an identical hole pattern on its opposite end that aligns with the rotor groove at 186 and the stator groove at 196. As the rotor rotates through the arc traversed by one of its grooves, the intersection of the opposing grooves of the rotor and the stator form a channel for passage of the ball between complete openings at each end of the rotor for input and output of the ball.
