Abstract: ABSTRACT % point of the leading edge of sync is used to           the  value  of  a  color  burst  locked  CW carrier,  and  a  quadrature  color  burst  locked  CW carrier.    The  acquired  value  of  each  of  the  two carriers are  split  into  two values  representing  the value on alternating horizontal lines.   This requires the generation of  a  one-half  horizontal  rate  signal (H/2) which can have an arbitrary phase relationship. The  H/2  phase  is  associated  with  each  of  the  four acquired  CW  carrier  values  and  that  information  is used by a computing device.   The H/2  signal is also used to gate a 30Hz vertical frame pulse to generate a 15Hz  V1  color  frame  pulse.    The  computing  device receives  the color  frame pulse and records the  time the  pulse  occurs.    This  information  represents  the minimum  and  sufficient  set  of  data  to  obtain  a complete measure  of  sync  to subcarrier  phase  (SC/H) and  color  frame  comparison.    By  multiplexing  the acquisition  electronics  between  two  video  sources, SC/H and color  frame comparisons can be made by the computing device. (Figure 2)

Abstract: A B S T R A C T     An automated system for examining a workpiece (6) that has been treated so that the flaws in it are revealed by concentrations of indicator on its surface to examine it for the presence of flaws, operates by scanning the surface of the workpiece (6) to provide an output signal representative of the luminance of regions of the surface of the workpiece (6),storing the output signals representative of the luminance of the regions of the workpiece in a memory (12),forming a first average signal representative of the average luminance of a number of regions (A,B,C) to one side of one region (D), forming a second average signal representative of the average luminance of a number of individual regions (E,F,G) to the other side of the one region (D),comparing the first and second average signals to determine which of the first and second signals indicates the greatest concentration of indicator, selecting whichever of these indicates the greater concentration of indicator and using it to derive a threshold value, comparing the derived threshold value with the output signal represen-tative of the luminance of the one region (D), and indi-cating that a flow is present in the workpiece (6) when the output signal representative of the luminance of the one region (D) indicates a greater concentration of indicator than does the threshold value. Using this technique of providing a variable threshold based on the highest average of the surroundings it is possible to achieve great selectivity in the examination of the work-piece (6) which takes account of differences in the background levels of indicator and enables automatic scanning of a workpiece (6) which is as sensitive as, or better than, the human eye and which is more reliable and consistent in its performance.

Abstract: ABSTRACT:          An actuating device for lifting and lowering the landing lever which carries the magnetic-head assembly of the drive mechanism of a magnetic-disk storage apparatus, whose front opening for the insertion of a flexible disk-ette can be closed by means of a pivotal front cover. A simple construction of such an actuating device, specific-ally for mechanism with a small mounting height, is ob-tained when the landing lever is associated with a later-ally projecting cross-arm, which is supported by a sup-porting plate which extends parallel to the landing lever. Via a guide lever the supporting plate is moved twords the diskette by a rod against a spring force as soon as the front cover is closed. The travel of the rod is then small so that it is not moved until the last stage of the closing movement of the front cover. This precludes an inadvertent displacement of the supporting plate.
