Abstract: Abstract of the Disclosure An aircraft take-off and landing system, wherein a sym-bol of a specified configuration is employed as an instrument means for take-off and landing.      This symbol is formed by directed extended references made up of electromagnetic pencil beams with a wavelength which is within atmospheric windows, produced by at least one source of electromagnetic radiation, positioned on a flight platform.           The electromagnetic pencil beams are oriented in space so that they determine the configuration of a symbol and, simultaneous-ly, indicate the course and glide slope of an aircraft take-off and landing path, set a spatical take-off and landing corridor wherein this path lies, and show additionally various limits of a take-off and landing platform or various marker points of an estimated take-off and landing path.  The method of aircraft take-off and landing, according to the proposed system, consists in flying an aircraft on a symbol of a specified configuration, its distortions being indicative of the aircraft's deviation from the estimated take-off and landing path and their magnitude being indicative of the deviation direction and value.  The pro-posed system may be made purely instrumental or visual, permit-ting both automatic and manual flying of an aircraft and is 100 or 1,000 times more accurate than conventional systems with localizers and glide slope transmitters.  The aircraft flying method, according to the proposed system, is characterized by exceptional simplicity and reliability, it remains consistent at all stages of a take-off or landing path.

Abstract: "PNEUMATIC TIRE"     ABSTRACT OF DISCLOSURE     This disclosure relates to a pneumatic tire construction which has a bead latch located axially outwardly of the rim flange in the lower sidewall area of the tire.  This construction provides a safer configuration for the tire when it is run flat or under abnormal conditions.  The bead latch prevents the bead from becoming unseated on the rim and moving into the drop center portion of the rim.  The bead latch may contain a decoupling means which allows it to act independently of the severe stresses in the sidewall when the tire is deflected or run-flat.

Abstract: PRINTER                 ABSTRACT OF THE DISCLOSURE         A printer is disclosed for use in printing indicia or the like on a sheet of recording medium by selective applica-tion of impulses of fluid.  The printer comprises a sheet support mechanism, a print head, fluid supply means, a valve assembly, and an input system.  The support mechanism supports and selec-tively advances the sheet of recording medium. The print head includes a one- or two-dimensional array of tubes arranged to form a dot matrix for printing alphanumeric characters on the sheet.  It may extend the width of the recording medium or be movable across it.  Connected to these tubes are the fluid supply means and a valve assembly that includes a separate valve for each tube for controlling the supply of fluid thereto.          In one embodiment of the invention, a heater raises the tempera-ture of the fluid passing through the tubes enough that printing takes place on the recording medium whenever the fluid is ejected from the tubes.  In another embodiment, a movable pin is mounted at the distal end of each tube in such a fashion that it is driven into the recording medium when a valve is opened.  In still another embodiment the movable pins are also heated enough that they affect the recording medium where they are driven into it.  The input system opens and closes the valves in accord-ance with input signals, such that the impulses of fluid applied to the tubes produce visual changes on the recording medium which represent such input signals.

Abstract: TITLE            SHEET DELIVERY MECHANISM FOR SHEET FED           PRINTING MACHINES                 ABSTRACT OF THE DISCLOSURE          A frame member extends from the last printing unit of a printing machine to a table upon which the freshly printed sheets are piled.  A plurality of spaced endless chains are reeved about idler sprockets positioned adjacent the printing unit at one end and about driven sprockets at the other end where the printed sheets are stacked in a pile.  Transversely extending gripper bars are secured to the chains and pass with the chains along a continuous path from the printing unit to the pile over a sheet guide assembly.  The upper end portion of the sheet guide assembly is supported by bearing assemblies which also support a plurality of suction wheels that are positioned between the upper end of the sheet guide assembly and the pile.  Actuating devices advance the bearing assemblies toward and away from the pile to thereby position the sheet guide assembly and the suction wheels for depositing a sheet of a selected size onto the pile.  Movement of the leading edge of a sheet over the sheet guide assembly creates a continuous cushion of air from the printing unit to the end of the sheet guide assembly.  The cushion of air supports the freshly printed sheet above the guide assembly and removed therefrom to prevent smearing of the sheet.  The printed sheet passes from the upper end of the guide assembly onto the periphery of the suction wheels which slow the movement of the sheet and exert a downward force upon the trailing edge of the sheet to prevent interference with the next following sheet and contact with any rigid surface that could smear the freshly printed sheet.

Abstract: ABSTRACT      A radio antenna which can be readily tuned to the exact frequency of operation, easily coupled to a coaxial feed-line with minimum standing wave ratio and/or which is normally vertical and can be used where horizontal space is at a premium, such as: indoors or on boats.  The antenna has a center loading coil, the inductance of which is adjusted by means of a split coaxial sleeve axially moveable relative to the coil.  The input impedance of the antenna is adjusted relative to the impedance of the feed-line by means of a coupling transformer, the transformation ratio of which is controlled by means of a coaxial split metal sleeve axially adjustable relative thereto.  A coaxial cable wound into a coil around a ferrite core attenuates the high radio frequency voltage on the end of the antenna to the feed-line. For indoor use, the antenna is housed in an extensible tubular housing which can be extended to engage the ceiling and floor of a room to hold the antenna in vertical position.

Abstract: MOLDED GLASS ARTICLES HAVING BULK HOMOGENEITY      AND OPTICAL QUALITY SURFACE                 Abstract of the Disclosure An optical glass article having a desired surface figure and demonstrating maximum theoretical light transmission can be prepared by forming a base anhydrous glass of defined compositional ranges, hydrating the glass, partially dehydrating the glass at a temperature above the softening point and, using an inert gas, at a pressure above the vapor pressure of water contained therein, and then molding a preformed blank of the glass against a die having a desired optical quality surface figure, the molding being under conditions sufficient to transfer the surface figure of the die to the glass.  The base glass comprises, in mole percent, about 70 to 82% SiO2, 10 to 17% Na2O and/or K2O, and 5 to 15% of an oxide or oxides selected from ZnO and PbO.  The water content of the partially dehydrated glass ranges from about 3 to 8 wt. percent and the molded glass has a substantially uniform refractive index throughout its bulk.  Homogeneous distribution of the water throughout the glass bulk appears to be assured by limiting the total water content to a range at which the diffusion coefficient of the water species (H2O, H+, and OH-) exhibits the greatest dependence on the total water concen-tration (i.e. the range at which the coefficient is a quasi-step function).

Abstract: DIFFERENTIAL RELUCTANCE TRANSDUCER SYSTEM      Inventor:  Peter Levesque, a citizen of the United States of America and resident of Jenkintown, Pa.     ABSTRACT OF DISCLOSURE          A displacement detector yielding an electrical output signal that is linearly proportional to the extent of input motion.  The input motion to be monitored is applied to the shiftable armature of a differential reluctance transducer constituted by a pair of transformers, each having a primary, a main secondary and an auxiliary secondary.  Fed to the primaries is a high-frequency drive voltage generated by an oscillator whose amplitude is regulated by a feedback loop in which a feedback voltage taken from the auxiliary second-aries is compared with a reference voltage to provide a control voltage that so regulates the drive voltage oscillator as to cancel out the effect of temperature on the output signal derived from the main secondaries.
