Abstract: COMMON CONTROL CONSTANT  SHIFT REFRAME CIRCUIT     Abstract of the Disclosure The disclosed reframe circuit utilizes common control circuitry to carry out a reframing operation for any, or all, of a plurality of time division multiplexed digital data groups which are out-of-frame.  An old data store is used to store a given number (m) of selected data bits, of each digital group, for two frames for framing comparison purposes.  A reframe comparator serves to com-pare, for each digital group, the m bit output of the old data store with m data bits that are two frames later in time.  A suitability store is used to record, for each group, which of the compared m data bits have had framing pattern violations and which appears as a suitable candi-date for the framing bit.  Based on the present set of comparisons and past suitabilities, a shift decoder searches for the framing bit within the current m-bit window until it has either marked all m bits unsuitable or has found the true framing bit within the window.  If all m bits are unsuitable, the data bits of an out-of-frame digital group are shifted m bit positions, m new bits are loaded into the old data store, the suitability store is initialized for these new m bits, and the described operation is repeated.  When the shift decoder finds a bit that is suitable for a given number of consecutive frames and hence is the true framing bit, the digital group is placed in-frame by shifting the data bits thereof one to m bit positions.

Abstract: ABSTRACT OF THE DISCLOSURE         The specification discloses apparatus for observing the stereoscopic image of an object, which includes a device for measuring distances between points on the stereoscopic image.   The stereoscopic image is produced by viewing the object from two different directions and arranging the two plane images thus produced so that one is seen by the right eye and the other by the left.  The measuring device provides one movable mark on the left eye image and one movable mark on the right eye image so that the distance between any two points on the stereoscopic image can be calculated by measuring the distances between corresponding points on each of the two plane images by appropriately moving the marks between the points.  In particular, however, the apparatus enables the marks on each image to be interlocked so that they are moved by the same distance in the same direction on each of the plane images.  When desired, one of the marks can be held stationary while the other is moved independently.  In this way the move-ment of the marks can be easily controlled and the control apparatus can be made quite simple as compared with previous apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE     N elementary transducers are distributed regu-larly along a line of scanning.  An ultrasonic frequency receiver is associated with phase lag means.          The distribution over n successive elementary trans-ducers of the phases corresponding to focusing at a predetermined distance or several successive dis-tances from the line is stored. That distribution corresponds to several Fresnel zones.  Switches first connect a generator to a group of n'  transducers corresponding to the central Fresnel zone of said stored distribution and later connect a group of n transducers to the receiver direct and via the phase lag means according to the stored distribu-tion(s).  The groups of n' and n elementary trans-ducers are shifted along the line at intervals of time.  The phase lag means may consist of inverter means causing a phase angle of .pi..
