Abstract

1336298 Digital measurement and control systems SIEMENS AG 3 Dec 1970 [3 Dec 1969] 57550/70 Heading G4H A tube is moved longitudinally (x) and rotated (y) so that a sensor detecting radial displacement (#z) traces a helical path over the tube, pulse trains representing movement in the three directions are counted at 14-16, and a store 25 holds the largest detected values of #z, together with the associated x and y values, and the stored values are used to control a press for straightening out the curvature of the tube indicated by the values #z. Values of #z greater than a predetermined tolerance are detected at 20 to cause the associated x, y and #z values to be supplied to an address decoder 17, the value of #z previously stored at 21 is compared at 22 with the current value, decoder addresses store 23 to store values of x and #z at different positions y, and comparator 22 passes the maximum value of #z together with the associated x and y values to store 25. The stored x and y values are used to control follow-up systems for longitudinal and angular positioning of the tube, and the #z value, combined with a zero offset and elasticity correction; controls the actuation of a straightening press.
