Abstract: A pump pressure control device includes a slidably mounted throttle control cylinder having a piston connected to a pump engine throttle to vary the speed of the engine. One side of the piston in the throttle control cylinder is open to pressure from an accumulator having a diaphragm or bladder therein. The accumulator, on the side of the bladder opposite the side open to the control cylinder, is precharged to a desired pressure. The other side of the control cylinder piston is open to the pressure in the pump output line which it is desired to regulate. The regulated pump discharge pressure is adjusted by sliding the control cylinder with respect to a fixed base. A directional flow valve functions to reverse the connections to the throttle control cylinder when the discharge pressure drops below a predetermined minimum.

Abstract: A method and apparatus for generating dry dust particles of a constant concentration from dry solid particles. The apparatus has a dust dispersion section receiving powdered material from a dust feeding section. The dust dispersion section includes a bed of beads subjected to a constant supply of air. An endless chain delivers a continuous supply of powdered material to the bed of beads and the air moving through the bed of beads. The chain is scrubbed by the beads and the air whereby the particles of powdered material are dispersed and entrained in the moving air. The particles move through a tube and are electrically neutralized with a radioactive source. A particle separator can be used to remove large particles. A photometer monitors the concentration of the particles emanating from the apparatus in aerosol form.

Abstract: A system and apparatus for the storage of energy generated by natural elements. Energy from natural elements such as from the sun, wind, tide, waves, and the like, is converted into potential energy in the form of air under pressure which is stored in a large, subterranean cell. Machines of known types such as windmills are driven by natural elements to operate air compressors. Air compressors pump the air under pressure to the storage cell. Air entering the storage cell displaces water from the cell which returns to a water reservoir as an ocean or a lake. Water locks the air in the storage cell. The stored compressed air is available upon demand to perform a work function as driving an air turbine to operate an electric generator.

Abstract: An annular sewing member mounted on the base of a heart valve and attached to heart tissue with sutures. The sewing member has spaced outwardly directed flanges connected with a body forming a central annular outwardly open groove adapted to accommodate heart tissue after the natural heart valve has been removed. The flanges are relatively thin and contain an internal core of cured plastic, as Silastic. The flanges can be fabric without an internal core. A heat shrunk collar or sleeve surrounded with cord retains the suturing member in movable assembled relation with the base of the heart valve to permit angular orientation of the valving member of the valve. Stitches extend through one of the sewing member flanges and the heart tissue attaching the sewing member to the heart tissue. The knots of the stitches are located under the second flange, thereby protecting the knots and minimizing clots. The flange without knots form a smooth surface with a thin endothelium tissue layer.

Abstract: A jet aircraft is equipped with powered helicopter type rotor blades and control mechanisms whereby it can take off and land vertically, yet in horizontal flight can operate at speeds and altitudes typical of jet aircraft. The rotor blades are foldably retractable to a compact locked, trailing position for horizontal travel and are readily unfoldable by a manually operated control mechanism within the aircraft. While the rotors are rotating, the blade pitch can be selectively controlled and, on power failure, will be automatically controlled to provide for same direction autogyro rotation. In one form, the wings and stabilizers are tiltable between substantially horizontal positions for normal horizontal flight and substantially vertical positions for vertical flight. The craft is ground supported by flexible legs.
