Abstract: A flying wing aircraft control for angle of attack and direction thereof, comprising retractile controlling surfaces rearward of the center of lift and along the trailing edges and extensible over the top and bottom cambers of the wing in spaced relation to the trailing portions thereof and with variable angular dispositions with respect to air flow over the cambers so as to establish the desired moment arm with respect to the lift center of the flying wing to control the same into and out of a nose-up attitude with respect to the line of flight and with respect to direction, as required.

Abstract: An internal combustion heat engine and cycle therefor comprising a two stroke cylinder and piston unit having a combustion chamber at the top of the cylinder, having a compression chamber at the bottom of the cylinder, and having a transfer chamber charged with compressed combustion support air transferred into the combustion chamber during initial movement of the piston in a first power stroke, followed by spark ignition and combustion to effect said power stroke with simultaneous compression in said compression chamber and with admission of compressed combustion support air into said transfer chamber during terminal movement of said power stroke, the compressed combustion support air being stored in the transfer chamber during a second exhaust stroke with simultaneous induction of air into the compression chamber.

Abstract: Method and apparatus for the separation of oil from water in an emulsion thereof, by inducing the oil-water emulsion into an elongated chamber at a temperature below the boiling point of water, and by recirculating a portion of the emulsion oil through the chamber at a boiling temperature well below the refining temperature of the oil, drawing off the product oil from the chamber end remote from said induction end thereof, and drawing off the water by-product as steam from the chamber above a controlled liquid level of emulsion-oil therein, waste heat from the product and by-product being conserved.

Abstract: An action toy for playing competitive marble games requiring skill and development of competitive spirit played against time in collecting marbles in a receiver from which they may be rejected, and embodied in a transparent containment cylinder in which the receiver rotates, and all of which is adapted to be revolved and tilted and moved bodily as a unit to apply force to throw the marbles into the receiver.

Abstract: A fuel injected free piston-turbine heat engine wherein a piston moves reciprocally within a cylinder to deliver gases to an impulse turbine powering a fan-scavenged two-stroke cycle operation of said piston, there being a low compression storage chamber of substantial volume normally open into the cylinder and closed by upward movement of the piston to withhold gases at combustion supporting temperature, there being a high compression auto ignition chamber of limited volume comprising the upper portion of the cylinder and isolated from said low compression chamber by said piston closure thereof for continued compression of combustion supporting gases by said piston movement to auto ignition temperature, and there being constant volume fuel injection means for injecting fuel at high pressure into the auto ignition chamber and at a progressively diminishing rate as the first mentioned storage chamber is re-opened and as the cylinder pressure decreases during the effective power stroke.

Abstract: A method and apparatus for the acquisition of emulsified shale oil from oil shale, by the granulation thereof, admixing of an emulsifier (water) therewith and by the subjection of vibration (sonic) thereto for the intimate comingling of the fluid admixture inducing withdrawal of said shale oil from the particulate matter thereof, followed by separation of the emulsion from said particulate matter.

Abstract: A fuel injected heat engine of the reciprocating type wherein a piston moves reciprocally within a cylinder to compress gases for the support of combustion and to be moved by burning gases to turn a crank with torque, there being a low compression storage chamber of substantial volume normally open into the cylinder and closed by upward movement of the piston to withhold gases at combustion supporting temperature, there being a high compression auto ignition chamber of limited volume comprising the upper portion of the cylinder and isolated from said low compression chamber by said piston closure thereof for continued compression of combustion supporting gases by said piston movement to auto ignition temperature, and there being constant volume fuel injection means for injecting fuel at high pressure into the auto ignition chamber and at a progressively diminishing rate as the first mentioned storage chamber is re-opened and as the cylinder pressure decreases during the effective power stroke.

Abstract: A jet thrust aircraft wing wherein the intake and exhaust are substantially coextensive with the leading and trailing edges, respectively; utilizing engine suction to induce intake of air and preventing build-up ahead of the wing by separating the same from the flow of air over and under the upper and lower wing surfaces; and utilizing engine exhaust thrust to induce controllable air flow through the wing and to induce longitudinal flow of air over and under the wing throughout its span.
