Title: System for automatically controlling gauge and the like
IPC: B21B1/32
Filed: 1966-11-23
Abstract: 1,109,075. Automatic size control. GENERAL DYNAMICS CORPORATION. Nov. 23, 1966 [Feb. 4, 1966], No. 52490/66. Heading G3R. A transverse dimension of a workpiece is reduced by passing it longitudinally through a machine in which the degree of reduction is automatically controlled in dependence on deviations of draft ratio and input thickness to maintain an output dimension of the workpiece substantially constant. In Fig. 1, material 7, uncoiled from a mandrel 5, passes through reversing rolls 4 and is re-coiled on a mandrel 6. Electrical pulses produced by generators 12, 13 driven by travel of the material before and after rolling are applied to a comparator 18 the output signal of which, on line 23, corresponds to deviation of the draft ratio from a datum value determined by a signal applied to line 19. A radiation or contact gauge 8 produces a signal, corresponding to deviation of ingoing thickness from a datum value, which is delayed by a unit 15 for a time equal to that required for the material to move from gauge 8 to rolls 4. This delay is produced in unit 15 by causing pulses from generator 12 to operate stepby-step switches which periodically charge condensers and later transfer those charges to the output circuit. The draft ratio and delayed ingoing thickness deviation signals are respectively amplified at 24, 21 and modified by potentiometers 25, 22 set in accordance with the datum values of ingoing thickness and draft ratio so that when combined in an integrating amplifier 30, a signal is produced representative of outgoing thickness, variations of which are then automatically corrected by control of an electrically or hydraulically operated roll separation adjusting device 3 of the wedge or screw type. Filtered signals from a further thickness gauge 9 may be applied to amplifier 30 to ensure greater accuracy in maintaining outgoing thickness at a desired value. A more accurate prediction of outgoing thickness may be obtained by also applying the product of the draft ratio and ingoing thickness deviation signals to input terminal C of amplifier 30. Correction may be effected by automatic control of mandrel drives 28, 29 instead of or in addition to roll separation. Application to tube drawing is referred to.

The counter 10 is reset to zero at the end of each sampling interval and thus when there is a large difference between Xf and X s , the counter is reset to zero before either subtractor becomes zero, but when the difference is smaller the operation occurs as described above. The sampling intervals are repeated in serial fashion until e is zero.

Abstract: 1,126,330. Tobacco smoke filters. EASTMAN KODAK CO. 16 Dec., 1965 [21 Dec., 1964], No. 53384/65. Heading A2C. {Also in Division D1] A cylindrical tobacco smoke filter rod is made from a tow of crimped continuous filamentse.g. of a denier less than 3 - by forming the tow into a band or ribbon, subjecting the band to tension sufficient to remove the secondary crimps therefrom, separating the filaments by longitudinally displacing portions of the tow with respect to adjacent portions, spreading the tow to a uniform constant width by means of a banding jet supplied with high velocity gas, applying a thin uniform coating of plasticizer to one or both surfaces of the spread tow, further separating the filaments and uniformly distributing the plasticizer therein by means of a gas jet and finally shaping the tow into a cylindrical form in which the filaments are fused to one another at random points by the action of a plasticizer. The filaments are displaced longitudinally by being passed between a bottom resilient surfaced roller and a top grooved roller pneumatically pressed against the bottom roller. The top roller has continuous or interrupted circumferential square-form cross-section grooves. The plasticizer is applied by means of rotating rollers -Fig. 2 (not shown) - which ares supplied with the liquid plasticizer by means of wicks connected to a plasticizer reservoir fed by a metering pump. The plasticizer may be triacetin, if the filaments are composed of cellulose acetate. To increase the removal of the phenol component from tobacco smoke, a high molecular weight polyethylene glycol liquid additive may be used to coat one side of the tow instead of the plasticizer. After the plasticizer has been uniformly distributed in the tow but before the cylindrical rod is formed particulate material - e.g. activated carbon, sodium bicarbonate, rice starch, cellulose acetate floc - may be added to the tow.

Abstract: 1,195,655. Drinking valve. UPJOHN CO. 12 Nov., 1968 [22 Dec., 1967], No. 53649/68. Heading A1M. [Also in Division F2] In a valve, which is adapted to supply liquid to, and to be controlled by an animal, such as a very small rodent, lateral displacement of T-shaped stem 57 projecting from an outlet 27, and hence tilting the stem head 58 with respect to an abutment surface 59 upon which the head normally rests, causes purely axial displacement of a further stem 56, 45, and, consequently, movement of a resilient valve head 41 in a direction away from its seat 37. Upon stem 57 returning to its normal, vertically orientated position, the valve head 41 is returned to its seated position partly by virtue of the pressure of fluid above it and partly by the resilience of four elements 49 which are formed integrally with the head 41 and with a ring 48 which is secured between the two valve housing parts 17 and 24 and the seat providing member 29. Disposed upstream of the further stem 56, 45, is a ball valve member 21 which in the event of a negative pressure being created in the valve, seats at 16 so preventing return flow into supply line 14, or in the event of the two body parts being separated, seats at 20 so preventing outflow from the supply line.

Abstract: 1456338 Inverting; DC-DC converting HASLER AG 16 Dec 1974 54339/74 Heading H2F [Also in Division H3] A D.C.-D.C. converter comprising transistors 5, 6, 13, 14 connected to a transformer 2, substantially as shown has a pulse generator 20 feeding the bases of control transistors 13, 14, the pulse frequency being more than twice the natural frequency in the absense of control transistors 13, 14, the pulse duration being greater than the turn-off time of transistors 5, 6 and less than the time required for substantial dissipation of energy in the transformer core. As described, assuming switching transistor 6 is conductive, control transistor 14 is turned on by the next pulse from 20, so as to remove stored charge from transistor 6 and eventually turn it off, this process being assisted by feedback from winding 4. Control transistor 13 is conductive during this time and prevents the feedback turning on transistor 5 until 6 is off. Over current protection may be obtained by connecting a current transformer 27 in the emitter circuit of 5 and 6 so that feedback from the secondary 28 to the bases of 13 and 14 minimises current in 5 and 6 while capacitor 8 is charging.
