Abstract: ACTUATING MECHANISM FOR GAS TURBINE ENGINE NOZZLES                   A B S T R A C T           A mechanism for varying the position of a plurality of nozzle vanes in a gas turbine engine.  The mechanism includes a single double-acting hydraulic actuating jack disposed between two bell cranks for simultaneously applying force to a ring gear at two diametrically opposed connection points.  The single actuating jack applies equal and opposite forces to the diametrically opposed connection points on the ring gear and reduces distortion producing stresses therein.          The ring gear simultaneously engages a plurality of individual gear segments rotatable with each individual nozzle vane in the engine.  Movement of the single actuator jack causes balanced rotation of the ring gear and simultaneous rotation of the nozzle vanes.

Abstract: FUSED COVERINGS              Abstract of the Disclosure Surfaces of thermally conductive substrates are covered with thermoplastic polymers, particularly certain fluorocarbon polymers by bonding said polymeric materials directly to surfaces of said substrates.  Adhesives, etchants, or the like are not used as bonding elements.  The process involves treating the surfaces to make them wettable by water and then cleaning the surfaces, if necessary, followed by heating the substrate to a temperature at which the polymer melts, gels, or softens (herein called the softening point), then placing the polymeric material into contact with the prepared sur-faces and applying pressure on the polymeric material to force it into fusing and bonding contact with the heated sur-face and then cooling the substrate to a temperature below the softening point of the polymer.  The products produced are preferably rolls.  In their covered form as produced by this invention they are useful as processing rolls in office copier's fusing systems, rolls used in food cooking processes, and the like.

The plate is mounted downstream of the vortex generating body at a prescribed distance which defines the vortex sensing site.  A plurality of plate and sensing embodiments is disclosed.  In one configuration, the plate is a flat rectangular plate spanning the entire inner diameter of the pipe and has its ends rigidly secured to the inner pipe wall.  The plate comprises upper and lower surfaces having a downstream length for enabling fluid vortex signals to occur alternately about the environment of each such surface,  The upper and lower plate surface flex, or move within a midsection between its mixed ends and that flexing causes vortex signal changes which are detected by a sensor, Other embodiments including cylindrical rods affixed to upper and lower plate surfaces; a free-to-move, rather than both fixed, plate end; ferromagnetic spheres and movement confining block cavities; as well as, central and shuttle sensor-plate configurations which do not require flexure of the plate for flowmetering are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE              The net energy used for digestion of wood chips compared to the prior art is reduced, and in fact a net energy gain   from the digestion process can be provided by proper black liquor heat recovery.  Black liquor is with-drawn from the digester and the solids concentration of the withdrawn black liquor is increased to at least about 60% while steam is generated having a minimum temperature at or higher than the temperature necessary to treat chips in the digester system.  Essentially all of the generated steam is recovered and utilized for treatment of chips in the digester system so that the chips are the final condenser for the steam and so that no condensing of the steam with water is necessary.  The waste heat that normally would be disposed of in the condenser water is utilized to preheat chips before or during digestion.  The concentrated black liquor is then burned to generate heat, and the heat generated by the burning is utilized further in the digester system for  chip  treat-ment, resulting in a net energy gain   from digestion.

Abstract: SPECIFICATION          Abstract of the Disclosure A marine riser including a uniquely designed three element connection structure and associated connecting and releasing means for the inhibiting of fatigue failure caused by moments and axial loads resulting from relative motion between the fixed ocean bottom and a floating drilling platform or ship, such as a semisubmersible rig.  The system includes a preloaded connection including a female member and a male member coaxially aligned and held in compression by a nut placed in tension.  The connection holds riser pipe sections together.  The connection is preloaded through a tool to a degree such that when a load equal to the yield strength of the pipe section material is applied to the pipe sections joined by the connector, the compressed faces of the male and female members do not separate from each other.          The degree of preload would be sufficient to maintain the contact between the compressed faces under expected working loads of the pipe sections.  The tool operates in conjunction with lugs located on the nut and a flange or platform with mounting holes located on the male member. A lock is provided on the nut to prevent the disengagement of the male and female members after they are brought into compression by the nut.  The position of the lock relative to the nut lugs determines the sustained preload of the connection.  Seals are provided between the male and female member to prevent leakage of fluid between the interior of the riser connector and the surrounding environment.  The connector also includes provision for the support and connection of sections of kill and choke lines.

Abstract: ABSTRACT OF THE DISCLOSURE          In a spot film device, the inner and main carriages for a film cassette are positioned with reversible servo motors.          An x-ray grid is mounted on the bottom of the main carriage and a cross grid is mounted on tracks beneath the carriage such that the cross grid may be used or not used for fluoroscopy and both grids may be used for radiography.  Field defining masks are also mounted for translating selectively with the carriage.          Individual reversible servo motor drives are used to advance and retract the masks and cross grid.  Springs that can stretch slightly are provided for absorbing shock or negating drive system momentum when the masks or grid are stopped abruptly.  Reduced power is applied to the mask and grid drive motors when the marks and grid reach their stops for holding them against their stops.          An independently movable palpator cone uses a reversible servo motor.  A latch for holding the palpator cone in position is self-locking, but is automatically releasable in response to the servo motor being commanded to reverse direction.  Cassettes can be loaded or unloaded from either the front or the rear of the spot film device.
