Abstract: ABSTRACT OF THE DISCLOSURE In a prime mover designed for industrial, vehicular and aircraft energy demands, these engines are known to include those principles of propulsion common to both the reciprocating internal combustion engine (RICE) and another form of energy convertor such as the turbine The nucleus of this machine to be known as motivator is the combination of a reciprocating compressor, a chamber (combustor) into which the compressor forces a large volume of air, an isolating back-pressure valve between combustor and compressor and an explosive pressure release means leading to an energy convertor. These elements including fuel supply and ignition means constitute the power producing contrivance named motivator. The power conversion section including turbine, jet tube, output shaft and reciprocating means comprise that part of engine receiving explosive power and transforming that power into rotary and reciprocating motion. In combination both sections (the complete unit) constitute a new concept in power production to be known as the Turbodyne engine. In this invention many innovations add to increased power and durability such as: 1 - new combinations in reciprocating means to permit using both ends of compressor to compact pressures in combustors; 2 - seal proof transfer reservoirs which may enable circulating liquids to cool critical areas in mobile components; 3 - rotary compressors in series with reciprocating compressors that may be used to multiply compression ratios; and 4 - multiple combustors that may be charged by combined reciprocating and rotary compressors and placed most advantageously for power delivery.

Abstract: S P E C I F I C A T I O N                        SLEEVE SHUTTLE AIR GUN     Inventor:  Stephen V. Chelminski ABSTRACT OF THE DISCLOSURE           A sleeve shuttle air gun is described which can be fired by a solenoid valve without dumping compressed air into the ambient prior to firing, thereby avoiding the generation of premature impulses caused by such dumping and avoiding the heavy duty complex solenoid dump valves of the prior art or the complex two-stage dump valves of the prior art.  The sleeve shuttle is automatically returned to its initial closed and sealed position after each firing of the air gun by the refilling flow of pressurized air.  Only one level of pressurized air is required for operation of this gun; there is no requirement for a separate low level pressure source to control the sleeve shuttle.  A relatively long acceleration path may be provided so that the sleeve shuttle attains a high velocity prior to opening the discharge ports for producing a sudden, powerful discharge.          The end of the sleeve shuttle advantageously travels completely beyond the discharge ports, and thereafter the shuttle motion is damped by interaction with damper ports located beyond the main discharge ports.  The trigger chamber for initiating firing is defined by an inner annular lip at one end of the sleeve shuttle engaging the firing seal in the initial closed position and by an outer annular shoulder (or flange) on the outside of the shuttle engaging with an encircling seal.  A stationary piston ring in sliding engagement with the inner wall surface ABSTRACT OF THE DISCLOSURE CONT'D     of the shuttle sleeve is replaceable for accommodating wear.          A replaceable stationary cylinder sleeve in sliding engagement with the annular shoulder on the outside of the shuttle sleeve also accommodates wear.  The volume of the firing chamber is conveniently changed by removing and replacing a chamber member on the opposite end of the air gun from the solenoid valve.          The instant of firing is advantageously monitored from the sudden increase in pressure occurring at the end of the return chamber toward which the sleeve shuttle moves when this air gun is fired.

Abstract: ABSTRACT OF THE DISCLOSURE A portable adjustable flow rate flare for smokeless burning of viscous liquid fuels such as crude oil, which comprises an assembly of four coaxial circular manifolds one each for pressurized fuel, water, atomizing medium and gas, supplying a plurality of burner heads, radially spaced, symmetrically, about at least the upper portion of the circular manifolds.  There is presently known in the art flares with one or a plurality of heads for burning off liquid fuel.  However, none of these known flares are capable of being easily transported; nor are they capable of handling fuels of varying viscositics under smokeless burning conditions.  The present invention seeks to solve both these disadvantages in the prior art.  The planes through each of the manifolds are parallel to each other and coaxial and adapted for mounting with axis horizontal on a base structure so that it can be moved from one location to another. Each of the burner heads comprises a central tube receiving pressurized fuel leading to an orifice of selected size and continuing downstream from the orifice with a tubular portion of selected diameter.  An annular chamber about the burner tube provides pressurized atomizing medium to the inside of the burner tube through a plurality of spaced openings so as to mix at high velocity with the flow of oil from the orifice and to atomize the oil.  Ignition means are provided to ignite the flame at the tip of the burner head.  Water spray may be provided at each burner head.

Abstract: ABSTRACT OF THE DISCLOSURE An improved power transfer device utilizes an input power source supplemented by an unbalanced weight assembly which increases the torque on an output shaft as a function of load associated with the device.  The input shaft is provided with a drive gear in operable engagement with an internal toothed ring gear, and the ring gear is provided with a plurality of dia-metrically opposed, radial extensions to which weight support arms are pivotably attached.  The remaining free ends of the weight support arms are attached to the outer extensions of a cruciform support and are further in parallel alignment with and fixedly secured to elongated weight, such securement being offset from a central portion of the weights.  A difference in load between the input shaft and output shaft results in the ring gear shifting in an unbalanced manner relative to the output shaft so as to deliver an additional torque to the shaft through the shifting of the unbalanced weights.

Abstract: APPARATUS AND PROCESS FOR MAKING SOLAR GRADE SILICON         ABSTRACT OF THE DISCLOSURE         A reactor apparatus      adapted for continu-ously producing molten, solar grade purity elemental silicon by thermal reaction of a suitable precursor gas, such as silane (SiH4), is disclosed.  The reactor apparatus      includes an elongated reactor body having graphite or carbon walls which are heated to a temperature exceeding the melting temperature of silicon.  The precursor gas enters the reactor body through an efficiently cooled inlet tube assembly and a relatively thin carbon or graphite septum, The septum       being in contact on one side with the cooled inlet      and the heated interior of the reactor on the other side, provides a sharp temperature gradient for the precursor gas entering the reactor and renders the operation of the inlet tube assembly substantially free of clogging.  The precursor gas flows in the reactor      in a substantially smooth, substantially axial manner.  Liquid silicon formed in the initial stages of the thermal reaction reacts with the graphite or carbon walls to provide a silicon carbide coating on the walls.  The silicon carbide coated reactor is highly adapted for prolonged use for production of highly pure solar grade silicon.  Liquid silicon      produced in the reactor apparatus      may be used directly in a Czochralski or other crystal shap-ing equipment.

Abstract: ABSTRACT OF THE DISCLOSURE     Loosely poured granular material is compacted by a burst of air under pressure which is built up in a space Q1 and is abruptly released through the outlet end of a passageway Q3 which opens toward the material surface.          While the pressure in Q1 is being built up and until released, it is restrained by a sealing member which concurrently covers the outlet side of Q1, the input end of passage Q3 and an accelerating space Q2.  The sealing member is held in place by a counterpressure in a space Q4 acting on a larger surface area than Q1.  The pressure is suddenly decreased in Q4, abruptly unbalancing the pressures and releasing the pressurized gas from Q1 into Q3 and against the surface.
