Abstract: PISTON AND EXTENSIBLE CYLINDER THEREFOR      ABSTRACT OF THE DISCLOSURE         A fluid pressure actuated piston of an aircraft multiple disc brake assembly is adapted to have an extended stroke by telescoping with a pressure actuated cylinder.  The piston is slidably carried in a fluid pressure actuated cylinder which, in turn, is slidably carried in a fixed carrier.  Initially, only the piston moves axially to extend its stroke with respect to the carrier.  The cylinder's structure and axial position with respect to the carrier creates a fluid pressure responsive surface area initially sealed from the effects of the fluid pressure. Axial move-ment of the cylinder is initially resisted by either mechanical or differ-ential pressure means until the stroke of the piston reaches a predeter-mined axial position to engage the cylinder.  Continued extension of the piston's stroke urges the cylinder axially to break the fluid seal and expose the heretofore unaffected surface area of the cylinder to fluid pressure thereby extending the stroke of the cylinder a predetermined axial distance.  The piston's maximum allowable stroke is thereby increased the same distance the cylinder travels.  The output force of the piston is essentially unaffected by the force imposed on the cylinder necessary to overcome the fluid seal and once extended, the cylinder does not provide any work force area.

Abstract: ABSTRACT         At the feed side of each antenna element having trans-mitting conductor paths formed in continuous meandering shapes and having distributed constant impedances are electrically connected a variable tuning unit including a voltage variable reactance circuit and an impedance adjusting reactance element, thereby constituting an antenna circuit.  A voltage variable capacitor is connected within the voltage variable reactance circuit.         Antenna feed terminals are connected through a coaxial cable to input terminals of a remote-set radio receiver.  A tuning control signal generated within the radio receiver is fed to a voltage variable capacitor within the voltage variable reactance circuit of the antenna circuit through the coaxial cable.  The tuning control signal allows the antenna circuit to resonate with a particular frequency within a frequency band, the frequency being variable.  The antenna element having the distri-buted constant inductance functions so as to have the best pos-sible antenna radiation efficiency at resonant frequency signal by being in combination with the variable tuning unit and the antenna element is considerably reduced in size.         At the resonant frequency signal, the characteristic impedance at the feed terminals of the antenna circuit becomes equal to that impedance at the receiving input terminals of the radio receiver connected to the antenna circuit, whereby an RF signal at the resonant frequency is selected and fed most effi-ciently to the radio receiver through the coaxial cable.

Abstract: Title:       "Method and Apparatus for Shaping Plastic Foams"     ABSTRACT OF THE DISCLOSURE   An improved method and apparatus is disclosed for shaping and forming plastic foams as a foamable extrudate is extruded through the orifice, preferably arcuate, of an extrusion die. Immediately adjacent and downstream of the die orifice are opposed sets of curved rollers, each having substantially the same center of curvature as the die orifice. The roller set on one side of the extrudate pass line is adjustable as a set with respect to and substantially parallel to the pass line, while the rollers of the set on theopposite side are adjustable individually each to float with controlled pressure against the extrudate as it expands and moves between the roller sets. Each roller is comprised of a plurality of thin, cylindrical, circular wafers which are drivingly interconnected and journaled on curved core shafts. The wafers of opposed rollers in each set are individually driven for rotation at a controlled speed so that each opposed pair of rolls acts as a traction drive for the extrudate as it exits radially from the die orifice, suchrollers controlling the expansion and movement of the extrudate while minimizing cell distortion. A surface finisher is provided downstream of the roll sets which comprises opposed extrudate engaging planar surfaces positioned on opposite sides of the extrudate, one being adjustably yet fixedly supported while the other is adjustably and floatingly supported pivotally at its center of gravity to exert a controlled floating pressure on the extrudate.
