Abstract: VTOL Exhaust Nozzle With Veer Flap Extension Abstract A gas turbine engine exhaust nozzle assembly having vertical thrust capability comprises a two-dimensional converging/diverging nozzle and a veer flap for forward thrust operation and a rotatable hood type deflector for vertical thrust operation, wherein the forward edge of the veer flap is attached to the downstream edge of the deflector hood.  During forward thrust operation, the hood and rear edge of the divergent flap portion of the converging/diverging nozzle are moved synchronously to maintain the rear edge of the divergent flap portion and the front edge of the veer flap adjacent each other such that the veer flap is aligned with and acts as an extension of the divergent flap portion of the converging/ diverging nozzle.  Preferably, means are provided to independently trim the orientation of the veer flap to maximize thrust.  A movable ventral flap defines the nozzle throat between itself and the deflector hood when the hood is deployed for vertical thrust.

Abstract: Title of the Invention A DEVICE FOR THE PRODUCTION OF A TELECENTRIC LIGHT BEAM              AND A PROCESS FOR USE THEREOF              ABSTRACT OF THE DISCLOSURE     In a device for the production of a telecentric light beam which is to be deflected over a defined region an incident light beam impinges upon a rotating plane mirror.  The light beam reflected thereby reaches the outlet of the device by way of a further co-rota-ting parallel plane mirror as a telecentric light beam.  There is thus obtained by simple optical means a deflection over a region which is considerable in comparison with the dimensions of the device, and the shifting of the deflected light beam occurs according to a simple mathematical function, more especially a sine function.  This simple mathematical relationship of a rotary angle and a displacement of the light beam enables an especially simple evaluation of measurement data.

Abstract: ABSTRACT   A fail-safe optical T-coupler for coupling a local terminal having at least one light source and at least one photodetector to a segmented optical data bus comprises an optically transparent acousto-optic cell, a pair of collimating lenses For coupling adjacent segments of the data bus to opposite ends of the acoustic-optic cell symmetrically with respect to the optical axis of the coupler so that there is a fail-safe path for transmitting remotely injected light from one segment of the bus to the next, and at least one acoustic driver for coupling acoustic bulk waves into the acousto-optic cell to selectively establish or intensify an ultrasonic grating along an acoustic axis. For interfacing the terminal with the data bus, the collimating lenses couple each light source and of the segments of the data bus to opposite ends of the acousto-optic cell symmetrically with respect to the acoustic axis of the coupler so that the ultrasonic grating Braff reflects locally injected light from each light source into the data bus. A similar relationship may be maintained between each photodetector and a corresponding segment of the data bus for Braggreflection of remotely injected light from the data bus segment to the photodetector. Alternatively, the coupler may be designed to passively reflect remotely injected light to the photodetector or photodetectors.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention provides a clamp which can be used to secure an accessory member to an abductor bar of an orthopedic-surgical table.  The clamp includes a clamp block pivotally mounted on the clamp and oriented with respect to the clamp to clamp an object therebetween.  A lever having a cam surface is mounted on the clamp so that the cam surface coacts with the internal mechanism of the clamp to orient the clamp block in an unclamped, intermediate and clamped position.  When the clamp is in the intermediate position, the clamp loosely engages the clamped object so that relative motion of the clamp and clamped object can occur.          Because the clamp can be stabilized on the clamped object by orienting it in the intermediate position the operator does not need to use a second hand to prevent the clamp from falling off the clamped object while the first hand positions and tightens the clamp.  Thus, the clamp can be secured to the clamped object in a one handed operation.The position of the lever reflects the position of the clamp block and thus indicates how tightly the clamp is secured to the clamped object.

Abstract: ABSTRACT         In a method of detecting the deflection of the blades (13) of a helicopter rotor as it rotates, a beam (14) of radiation from a transmitter/receiver (11) encounters the tips of the rotating blades which send reflected signals to the receiver.  The phase difference due to deflection of the blade tip can be used to give a measure of the deflection of each blade, and that can be displayed graphically for the various blades at various speeds.          The measured deflections can be recorded for subsequent use.  In prior proposals the blade tips were examined visually but no per-manent recording was made.

Abstract: ABSTRACT OF THE DISCLOSURE           A metal tubing joint to connect lengths of pipe is made either by forcibly drawing a ductile sleeve over ends of pipe in telescopingly engaged overlapped relation, the sleeve being plastic-ally strained and enlarged permanently in diameter by from 1% to 7% by the drawing operation, or by forcibly drawing an enlarged end of another pipe over the pipe end to plastically strain the enlarged end further by at least 1%, and the heat developed in distending the metal and in frictional work during rubbing contact is controlled so that the members, when cooled to ambient temperature, have relative diameters at their engaged surfaces such that the remanent circumfer-ential tensile stress is the wall of the outer member is considerably reduced below the peak stress at maximum distention, and the members act as opposed tension and compression springs within their elastic limits. The joint allows repeated application of rated fluid pressures without risk of plastically straining the outer member.         The pipe may be warmed prior to assembly so that a temperature gradient exists, decreasing to the entry end, or the leading ends of the sleeve is coned to develop friction heating of the pipe surface as a constricting zone of the sleeve end is forced over it, or both means used to attain the condition that the pipe is warmer by from 12°C to 100° than the sleeve at the conclusion of the drawing step.          A heat sink may be used on the exterior of the outer member to lower its peak temperature at the leading end, or along its whole length.

Abstract: DIGITAL PWPF THREE AXIS SPACECRAFT ATTITUDE CONTROL          Abstract A digital system for  controlling  the  attitude  of  a spacecraft  (14),  e.g., a satellite, with respect to three orthogonal axes.  The system can control satellites (14) in parking orbit, transfer orbit, or final operational orbit, whether  or  not the  satellite  (14)  employs one  or more momentum wheels.   A processor  (2)  converts weighted data from   spacecraft   sensors   (12),   representing   angular orientation and angular velocities about each of the three axes,  into thruster pulsetrain signatures  to command  the firing of each of six thrusters positioned about spacecraft (14),  a positive and a negative thruster being positioned to impart both directions of angular momentum about each of the  three  axes.   Each  thruster  pulsetrain  signature is created  once  every processed  error  cycle  period T1,  and contains a varying number of pulses of varying widths.  A negative feedback PWPF loop (2, 16, 20, 22, 24) is actuated for each of the three axes, preferably several times each T1 in order to achieve better thruster on/off resolution.          The PWPF loops are preferably implemented by digital means.          Serial-out  shift  registers  (44,  46)  load  the  thruster pulsetrain  signatures  into  means  (48,  50,  52,  54)  for firing  the  thrusters,  preferably  after  splitting  the signature pulses into clone pulses in order to minimize the impact of errors due to asynchronization between the clock which  loads  the  registers  (44,  46)  and  the clock which shifts these registers.  Data extenders (40, 42) eliminate possible gaps caused by asynchronization, and thus prevent unwanted on/off thruster switching.

Abstract: SIMULTANEOUSLY LOCKING AND UNLOCKING DEAD BOLT          AND LOCK LATCH WITH PANIC UNLOCKING                ABSTRACT OF THE DISCLOSURE           Extending a dead bolt into a locked position turns a crank that releases a lock release plate from an unlocked position which in turn releases a slide.  Upon its release, the slide responds to springs and forces a tooth into a notch of an actuator to lock a latch bolt.  To unlock the latch bolt and the dead bolt, the dead bolt can be directly retracted, whereupon the crank engages the lock release plate to move it back to its unlocked position.          The lock release plate during this travel picks up the slide and withdraws the tooth from the actuator, freeing the latch bolt assembly.  When locked, the latch bolt and the dead bolt can be simultaneously unlocked by rotation of an inside operator which produces rotation of a double-lobed cam.  One lobe of the cam moves the slide against the force of the springs sufficiently to clear the tooth from the actuator.  The cam continues to move the slide so that the slide engages the crank and rotates the crank to retract the dead bolt and force the crank into its unlocked position in a detent of the lock release plate.  The force of the springs on the detent maintains the crank in its unlocked position.  After the tooth clears the actuator, a dog on the cam picks up the actuator to rotate it and withdraw the latch bolt.  For lever-actuated outside opera-tions, the actuator has a finger engageable by the slide that in turn follows the rotation of the double-lobed cam. A lost motion space between the roller and the finger per-mits withdrawal of the tooth from a notch in the actuator prior to rotation of the  actuator.

The program codes and key codes are retained in a memory so that upon reproduction the key code can be read out of the memory and fed to a descramble pattern generator for descrambling the reproduced scrambled signal.  By placing the program code and key code at the end of the scrambled program the scrambled signal cannot be descrambled until the entire program has been first received.  By dividing the memory into permanent and temporary memories and adding an identification code to the transmitted scrambled signal, which selects either the permanent or temporary memory, and counting the number of times that the temporary memory is read out there can be a limitation placed on the number of times that the scrambled program is reproduced and decoded for viewing.  Once a selected number is reached the contents of the temporary memory are erased, thereby preventing descrambling of the reproduced signal.
