Abstract: 1,262,921. Controlling feeds and speeds. SUD - AVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. 22 Jan., 1969 [26 Jan., 1968], No. 3534/69. Headings B3K and B3T. In a machine tool such as a lathe or milling machine which has a tool holder, a workpiece holder and means for causing relative displacement at constant speed between the tool holder and the workpiece, additional means is provided to impose on the constant speed a continuous and progressively variable speed whereby the machine will produce continuously and progressively changing contours or surfaces on a workpiece, for example, variable pitch screwthreads. In one embodiment a workpiece 33 is secured to and rotatable with the machine spindle 32 which is driven by way of belts and gearing 35-42 from a variable-speed motor 31. A tool slide 22 movable parallel to the workpiece by a lead-screw 61 is releasable therefrom by a split nut 25. The constant-speed drive to the lead-screw is from the motor 31 by way of the spindle 32 through gearing 43, a differential unit 46, gearing 60 and a coupling sleeve 62. The continuously variable speed drive is superimposed on the constant-speed drive by way of the differential unit, whereby, a cam 48 driven through gears 47 from the machine spindle 32 actuates a cam follower 49 which controls an hydraulic ram 51 which in turn actuates a rack 52 and pinion 53a which via gearing 53 rotates the cage 54 of the differential unit thereby adding to the speed of traverse of the tool slide. The traverse of the tool slide is controlled by engagement and disengagement of the split nut 25 with the lead-screw 61 and the rapid return of the tool slide after each machining pass is effected by a rack-and-pinion 21, 20 driven from a reversible hydraulic motor 8 through gearing 11-19. The rack-and-pinion is also operated to pre-load the nut 25 in the direction of traverse thereby reducing the power required from the motor 31 to effect traverse of the tool slide. In an alternative embodiment, e.g. on a milling machine, the continuously variable speed drive is effected by a stationary cam 74 mounted on the machine bed 72, the cam follower 75 traversing the cam as the machine table 73 traverses the bed 72.

Abstract: 665,298. Control of A.C. motors. BENDIX AVIATION CORPORATION. Feb. 11, 1949. [June 16, 1948]. No. 3840/49. Class 38 (iii). [Also in Groups XX, XXXVI, XXXVIII and XL (c)] In follow-up-control system (see Group XXXVIII) the error signal obtained from a ring modulator 179, which will vary in magnitude and 180 degrees in phase according to the magnitude and direction of the error, is used to control a two-phase reversible induction-servomotor 177. The motor is energised from an A.C. supply 207 through a double-wound centre-tapped saturable reactor 200 and phasing condenser 213 so that it is normally stationary. The control (error) signal is applied through R.C. filter circuits 189, 210 and 190, 211 to push-pull valves 191, 192 having the other winding of the saturable reactor 200 in their anode circuit. In the absence of signal the valves are balanced by adjusting the tapping on the cathode resistor 209. The signal causes the impedance of the two halves of the reactor to vary, and hence the motor 177 to revolve in one direction or the other.
