Abstract: ABSTRACT OF THE DISCLOSURE A relatively-small-diameter conductive cylindri-cal tubing, or metallic rod element is wound helically in the shape of the desired electrostatic metallic shield element.  The turns of the metallic coil, thus formed, may be cemented, soldered, welded or otherwise fastened to-gether to thereby provide rigidity to the metallic shield, if desired.  The turns of the metallic coil may, however, be separated from one another by a space.  One or both ends of the coil may be bent transversely away from the shield's surface for use both as a physical support during casting, or encapsulation, and, alternatively, as conducting leads for grounding purposes, or for terminal connection purposes. The body portion of the insulating member may be composed of any suitable casting material, such as resinous material, either epoxy resin, or polyester resin, or Butyl rubber.           The insulating body may either be a spacer for spacing a high-voltage power-conductor member within an outer grounded piping system in gas-insulated power trans-mission equipment, for example, or, alternatively, the in-sulating member may be a somewhat conventional-type term-inal-bushing body portion, providing an insulated con-ductor-lead into suitable electrical equipment, such as circuit-breaker equipment, current-transformer equipment, potential-transformer equipment, or like electrical appara-tus, for example.

Abstract: GAS TURBINE CONTROL         Abstract of the Disclosure A fuel and burner variable geometry (BVG) control for a gas turbine engine.  Fuel is controlled in response to the product of desired overall fuel-air ratio and a value of air flow derived from gas generator turbine speed.  The desired fuel-air ratio is controlled by a speed governor, and by acceleration and deceleration limits varied as a function of measured burner inlet temperature.  A compensated turbine inlet temperature (TIT) signal is derived from measurement of actual turbine inlet temperature and acceleration or decele-ration compensation based upon rate of change of the desired fuel-air ratio.  The difference between the compensated TIT and the burner inlet temperature (BIT) is the burner tempe-rature rise.         The setting of air flow control devices in the com-bustion apparatus (BVG) determines the ratio of primary to total air.  The desired ratio to control BVG is computed by dividing burner temperature rise by flame temperature rise. Flame temperature rise is the difference between the desired flame temperature and the measured BIT.  The desired flame temperature is scheduled as a function of BIT and BVG.  The ratio of primary to total air may be limited temporarily during starting of the engine.

Abstract: ABSTRACT OF THE DISCLOSURE        A one-piece, sheet metal multi V-grooved pulley has a circular hub wall integrally connected with a cylindrical side wall, which side wall terminates in an open end opposite of the hub wall. A series of outwardly opening V-shaped grooves is formed by pairs of V-shaped flange walls in the cylindrical side wall.  The pairs of flange walls decrease in metal thickness progressively from the hub wall toward the open end. The V-grooved pulley is made by forming a cup-shaped stage blank having a bottom hub flange wall and a connected outer cylindrical wall terminating in an open end.  The stage blank is formed by roller spinning an outer annular portion of a sheet metal disc along a stepped cylindrical surface of a headstock die. A series of integrally connected cylindrical surfaces is formed along the interior of the cylindrical wall of the stage blank by the roller spinning operation.  The metal thickness of the cylin-drical cup wall sections defined by the stepped surfaces decrease in a step-like fashion progressing from the hub flange wall to-ward the open end.  A series of V-shaped grooves then is cold rolled in the cylindrical wall by inwardly displacing the center of each of the stepped cylindrical wall sections to provide pairs of V-flanges which form the V-shaped grooves.  Each cylindrical wall section of the series provides the metal for the pair of V-flanges which forms the V-shaped grooves, whereby the metal thickness of the V-flange pairs decrease progressing toward the open end of the pulley.

Abstract: SPECIFICATION          WAYNE E. NUTTALL and WILLIAM H. PAGE          A LOW EMISSION MULTIPLE SEALING SYSTEM FOR FLOATING ROOF TANKS             ABSTRACT OF THE INVENTION A low emission multiple sealing system for a floating roof liquid hydrocarbon storage tank is provided.  The sealing system utilizes a double sealing arrangement in addition to, in a preferred embodiment, a conventional weather seal.  The double seal-ing arrangement includes two functionally independent generally toroidal shaped sealing elements positioned one above the other and filling the annular gap between the floating roof and the inner surface of the storage tank.  In order to provide for in-creased sealing efficiency and to eliminate the deleterious effects of wind and other ambient conditions, the double sealing elements are configured having effective vapor sealing efficiencies and are separated from one another a distance which will maximize the runback, to the tank, of liquid left on the inner storage tank wall during diurnal contraction and/or on liquid hydrocarbon unloadings.  Additionally, elements are provided in the volumetric space between the two seals for minimizing the volume between the two in order to create a more easily saturated space.  As a result, runback of liquid to the tank is increased.  The specific configuration of the seals and their spacing relative to one another and to the floating roof provides for a more efficient low emission sealing system for reducing vapor emissions to the ambient atmosphere.

Abstract: DISPLAY DEVICE HAVING IMAGE SENSE        REVERSAL CAPABILITY                          Abstract of the Disclosure An improved display device utilizes an electro-optical panel including an electrically insulating layer and a light-modulating layer of dipole, light control par-ticles dispersed in a transparent matrix.  An imaging electric charge pattern is impressed on the panel to establish a particle orienting field thereacross.  The light modulating pattern thus created in the modulating layer is selectively changed between positive and negative image sense by selective application and removal of a uniform field of the same polarity as, but lesser magnitude than, the imaging charge pattern.  The stored image pattern is erasable by application of a reverse polarity field.  Preconditioning the panel with a uniform field facilitates a positive light modulating pattern in the first instance.

Abstract: TITLE          SYSTEM FOR SYNTHESIZING STRIP-MULTIPLEXED HOLOGRAMS            ABSTRACT OF THE DISCLOSURE         A system for synthesizing strip-multiplexed holograms, with or without coherent light, from a plurality of two-dimensional images.  The two-dimensional images may be formed by a motion picutre film of a rotating subject such that each image is a view of the subject from a different angle.  The images are then non-diffusely and anamorphicly projected by a lens system which compresses the image in a first direction and expands the image in a second direction orthogonal to the first direction.  The projected image or object beam is then superimposed on the refer-ence beam by a lens-beamsplitter which transforms the substantially planar object beam into a substantially cylindrical wavefront and projects it and the reference beam onto a holographic recording medium.  As each two-dimensional image is sequentially projected, the holographic recording medium is shifted so that a plurality of laterally displaced strips are recorded.  Alternate embodiments of the system utilize a holographic diffraction grating contact-printed by means of the object beam onto the holographic recording medium instead of a reference beam to produce an interference pattern, a video projection system instead of a cinema film pro-jection system, a three-color image of coherent or nondiffuse light instead of a monochromatic image, and/or three separate holographic diffraction gratings produced by three different mono-chromatic sources of coherent light instead of a single holographic diffraction grating in order to produce multicolor holograms, or a reference beam or reflective surface relief diffraction grating or Fresnel mirror behind the holographic recording medium for synthesis of reflection holograms instead of transmission holograms.          The system is capable of synthesizing image plane holograms by using a variety of disclosed processes.  Techniques are also disclosed for synthesizing holograms which can be dis-played flat and illuminated with a point light source without introducing image distortion.
