Title: Machine tool control system
IPC: B23Q35/18
Filed: 1969-02-11
Abstract: 1,214,432. Copy turning. H. ERNAULT-SOMUA. 11 Feb., 1969 [13 Feb., 1968; 13 Jan., 1969], No. 7218/69. Heading B3T. [Also in Division G1] In a copying machine tool, the position of a movable machine element primarily positionally controlled by a permanent circulation hydraulic servomotor copying control system is corrected by measuring the positional error of the element and accordingly varying the rate of liquid supply to the hydraulic copying servomotor.  As shown in Fig. 5, the diameter of a finished workpiece 9 is measured by a capacitive transducer 28 connected into a bridge circuit comprising also capacitors 46, 47 and an adjustable reference capacitor 40. Any bridge unbalance operates a relay 48 or 49 depending on its sense to cause a motor 50 or 51 to adjust the reference capacitor 40 to balance the bridge.' This also moves the wiper 54 of a potentiometer 55 to cause a variation in the speed of the motor 33 driving the circulation pump 19 until the output of a tachogenerator 34 balances the new voltage tapped off from the potentiometer 55. The variation in pumping rate causes an hydraulic servomotor 10 to correct the position of the cutting tool 8 relative to the template feeler 6. The workpiece 9 is now removed and switch 60 rises to substitute a calibration capacitor 66 for the transducer 28 and disconnect the clutch 56 whereby motor 50 or 51 drives the reference capacitor 40 back to its initial value to rebalance the bridge without further altering the speed of the pump 19. In a machine having a plurality of cutting tools, a corresponding number of correction systems may be provided. An alternative arrangement (Fig. 7, not shown) uses a constant output pump (71) and a pressure control valve (70).

Filed: 1945-03-26
Abstract: 595,428. Impact pulverizers. RUPRECHT, L. March 26, 1945, No. 7637. Convention date, June 29, 1944. [Class 59] A beater mill in which a current of air is passed through to remove pulverized material, is characterised by the provision of means for causing air in the chamber containing the beaters to circulate around a helical path about a circular axis lying in a plane parallel to the plane of rotation of the blades so that as shown in Fig. 7 the air passes, on each revolution, radially outwards into the blade path, then axially away from said blade path and finally axially towards, but radially within, said blade path before re-entry, in the radially outward direction, into said blade path ; means for introducing said external air into the helical airpath in a direction substantially tangential thereto ; and a centrifugal separator concentrically mounted with respect to the blades and adjacent a part of said helical air-path for withdrawing fines and returning oversized particles to the helical path. A cylindrical mill chamber 11, with a transversely corrugated liner and an imperforate peripheral wall, has two end parts 12 which, with members 13, form two fan chambers 14. A shaft 15 drives a rotor, formed by two discs 20 pivotally carrying tapered beater blades 22 on arms 23, and discs 26 with spaced radial blades 25 ; alternatively, these blades 25 may be formed on the rotor discs 20. Air is drawn, by suction fans 31 preferably driven by the shaft 15, through chambers 65 and annular air inlet slots 30 into the mill chamber where it circulates as shown in Fig. 7, then to pass out through the centrifugal separator 25. Material fed from a shoot into the mill is beaten by the blades 22 and the fines are carried out in the air stream, while coarse grains are returned by the centrifugal separator 25 to the beater blades. The size of the particles so rejected may be varied by varying the length, spacing or speed of the separator blades or by varying the air velocity, by means of a damper 38 for example. Two different degrees of fineness may be accepted simultaneously, by differing the adjustment, at either end of the mill. One independently driven fan may replace the two shaft-driven fans 31.
