Abstract: ELECTROMECHANICAL TORSIONAL OSCILLATOR WITH RESONANT FREQUENCY AND AMPLITUDE CONTROL                   ABSTRACT A limited rotation electromechanical torsional oscillator for driving a mirror in an optical deflection system. A drive armature is mounted on a torsion bar at the opposite end from the torsion bar support.  The ends of the armature lie in an air gap between two pole pieces.  The magnet flux in the gap is caused to vary by means of a drive winding which results in armature rotation.  Resonant frequency is varied by adjustment of the length of the torsion bar and the flux density.  Q is varied by means of resistance in series with the drive winding.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a photographic apparatus which includes an exposure control system having shutter blade elements with respective selectively shaped aperture openings therethrough which, depending upon the position of the blades, symmetrically overlap over a light entering exposure opening within the camera to define an effective scene light admitting aperture.  During an exposure interval, the blades move simultaneously in correspondence with each other to define a progressively variable effective aperture opening over the camera light entering opening.  The exposure control system additionally includes exposure control cir-cuitry having a photoresponsive element therein as well as means responsive to the output condition of the photoresponsive element for arresting the shutter blade movement to define a maximum effective size aperture opening as a function of a first select scene light condition during a photographic exposure interval.  Means are also provided for thereafter initiating the closure of the shutter blade elements to terminate the exposure interval as a function of a second select scene light condition.

Abstract: Method and Device for Supervising the Speed of an Object ABSTRACT OF THE DISCLOSURE         A system for supervising the speed of an object, such as a vehicle, relative to a reference point, wherein a TV-camera is utilized.  The TV-camera is mounted at the refer-ence point and directed at a certain, perferably right angle to the direction of movement of the object, so that the field of view of the TV-camera includes a measuring distance.  The video output signal from the TV-camera is fed to a black level sensor which in turn activates a pulse generator while the image of the object is passing between two given marking lines on the TV-image corresponding to the measuring distance.  The pulses thus generated are counted, and the counted number of pulses constitutes a measure of the speed of the object (e.g. inverse proportionality).

Abstract: Abstract of the Disclosure In the manufacture of a communications cable, a moisture barrier comprising a corrogated metallic tape having inwardly and outwardly facing major surfaces is wrapped longitudinally about an advancing cable core to form an overlapped seam, with at least a portion of each of the major surfaces which form the seam being precoated with an adhesive copolymer material.  Heat is applied to at ?east the portions of the moisture barrier which form the seam while the portions are spaced apart a distance sufficient ' o permit a stripe of adhesive copolymer material in molten form to be introduced into engagement with a longitudinal edge portion of the precoated outwardly facing surface which is destined to form the seam and which is disposed generally horizontally.  Then the cable core and moisture barrier are advanced between coacting rollers which apply forces to the moisture barrier to cause the spaced apart portions to engage each other with the stripe engaging the precoated longitudinal edge portion of the inwardly facing surface which forms the seam and filling the spaces between associated corrugtions to form an essentially continuously sealed seam.  A longitudinally extending mandrel supports the barrier during the application of the forces to preserve the configuration of the enclosed core and to prevent damage to the core or the moisture barrier.

Abstract: TITLE     ADAPTIVE DIGITAL DELTA MODULATION                  FOR VOICE TRANSMISSION     INVENTORS     David E. Dodds Andrzej M. Sendyk Donald B. Wohlberg ABSTRACT OF DISCLOSURE        The adaptive delta modulation system represents an approximation of an analog voice signal by a stream of signal binary bits each occupying a fixed time period.          This stream of binary signals is produced by periodically sampling the analog signal and generating a binary bit for each period, the logic level of the binary bit being dependent on whether the sampled signal is greater or smaller than the approximate signal of the previous sample.          The decoder apparatus which converts the stream of binary bits back to the approximate analog signal includes a capacitor integrator which is periodically charged or discharged by a pre-determined amount in response to each bit so that the signal on the capacitor follows approximately the value of the original analog signal.  The charging or discharge during each period is determined by the logic level of the binary bit.          In addition, the step size increases or decreases approximately exponentially for successive periods with the step increasing in response to successive similar signal binary bits and decreasing in response to successive dissimilar bits.  This increase  or decrease in step size is achieved by storing a binary step size number S in a register and adding or subtracting a fraction of the number to or from itself during the particular period, this produced a new step size number for each period.  In addition, each added fraction may be increased by a fixed least significant number to enhance step size recovery between a transmitter and a receiver.  The charging and discharging of the capacitor integrator is accomplished by a pulse that has a width which is directly related to the value of the S number.  The width of this control pulse controls the conduction time of constant current sources which are connected to the integrating circuit to charge or discharge the integrating capacitor and produce the approximate signal.

Abstract: SENSOR CIRCUIT                  Abstract of the Invention A circuit for sensing the motor stator voltage on any one or more phases of an AC electrical drive system.  In a three phase system, all three phases of the motor terminal voltage are applied to a modified six-pulse rectifier bridge which in turn feeds a loading resistor.  A resistor is added in series with each diode pair of the six-pulse rectifier bridge in order to provide any degree of attenuation of the peak voltage developed across the load resistor by simply varying the resistance values of these series input resistors and the load resistor.  The resulting DC voltage generated across the load resistor is then fed into a differential amplifier (stage) where the voltage is attenuated and impedance isolated from the source to provide a DC output which is proportional to the average applied AC motor stator voltage.
