CONTACTLESS DETERMINATION OF THE SITUATION OF A STRAIGHT-LINE CHARACTERISTIC OF AN ARTICLE.

NON-CONTACT DETERMINATION OF THE POSITION OF A RECTILINEAR FEATURE OF AN ARTICLE

A high resolution CCD video camera (6) is positioned and aligned with respect to an illuminated article (7) so that a straight edge of the article, or a straight line junction between a bright zone and a dark zone of its surface, crosses the field of view of the camera in a direction substantially parallel to the rows of the camera's orthogonal array of rows and columns of light responsive elements,to divide that field of view into bright and dark zones. A frame store and digitiser (9) converts the individual signals generated by the elements into digital grey values. The grey values derived from the elements of each row are summed by a computer (10) to produce a linear array of summation values positionally related to the respective columns, and the computer then determines the position of the edge or junction to a subcolumn spacing accuracy by determining the mean value of two of the summation values selected respectively from a row receiving energy from the bright zone and one receiving ...

Device for detecting longitudinal cable movement

A depth measurement system produces independent signals, each presumably corresponding to the same movement of a wireline if produced under ideal wireline measurement conditions. The system utilizes the signals to provide an accurate and repeatable signal under varying wireline measurement conditions and is particularly suitable for driving a recorder for depth recording and merging measurements from tools lowered in the borehole on different runs and to detect slippage between the wireline and a tangential wheel used to provide one of the signals. Slidably mounted measurement wheels insure tangential engagement of opposite sides of the wireline with equal pressure. Low-load signal generators each responsive to the rotation of the opposing wheels provide independent signals, each ideally corresponding to the movement of the wirline engaged between them. Magnetic marks written on the wireline are sensed and provide yet another independent signal. Automatic processing of these signals provides alarms and corrections for slippage, variations in measurement tension, and cable stretch.

Improvements in or relating to a Yarn Stretch Indicator

1,160,545. Measuring stretch or shrinkage of yarn. LEESONA Ltd. 19 Sept., 1966 [1 July, 1965], No. 27833/65. Heading G4H. The amount by which yarn stretches or shrinks after passing through, for example, a size bath 12, is measured by comparing the number of pulses transmitted to a first decatron counter 19 by a transducer 17 sensing the rotation of a roller 11 with the number of pulses from a second transducer 17 transmitted to a second decatron counter 21 as a roller 13 on to which the yarn 10 is wound after it is passed through the size bath 12 rotates. In the embodiment described the counter 19 counts up to a thousand pulses and then switches a diode in the control box 20 to prevent any further pulses being received by either counter. If the counter 21 has then counted 1,027 pulses it will display 27 to indicate a stretch of 2À7% but if, for example, a count of 965 is given the percentage, shrinkage is obtained by subtracting the indicated figure from one thousand. The counter 21 has three indicator dials which respectively indicate a percentage stretch of from 1% to 1%, 1% to 10% and over 10%.

Instantaneous tape position determination in cassette - involves measurement of transfer speed and physical characteristics of tape

The instantaneous position of a tape used for recording and reproduction is calculated from constants representing physical characteristics. The speed of transfer of tape from one spool to another is also measured. Pulses are generated proportional to speed or rotation of eachspool in a tape transfer system. High frequency clock pulses are accumulated in registers to determine time of rotation for each spool from the number of pulses generated proportional to speed. Physical characteristic constants for cassette is use are stored in memory and used in calculations to determine tape position.
