Abstract: 723,622. Automatic speed control. MASCHINENFABRIK WINKLER, FALLERT & CO., AKT.-GES. July 4, 1951 [July 11, 1950], No. 15844/51. Class 38 (4). [Also in Group XVI] In a web-renewing mechanism, a replacement roll is accelerated, by an electric motor that is not adjustable as to speed, but is switched on and off, prior to a web-splicing operation, such that its peripheral speed is the same as the linear of a web unwound from an expiring roll. As shown, a differential gear, Fig. 1, is driven through chains 17 and 23, respectively, by a roller 9 engaging the replacement roll 7 and a web-engaging roller 6. When the linear speed of the web 3, being unwound from an expiring roll 4, exceeds the peripheral speed of the roll 7 an electric motor 32 is energized to drive the roll through a belt 34. The roller 9 drives a sprocket wheel 18, Fig. 5, by the chain 17, such that a shaft 21, carrying the sprocket 18, drives a pinion 20. An internally-toothed wheel is driven through a sprocket-wheel 24 and the chain 23 by the roller 6. A disc 26, carrying a pinion 27 engaging the pinion 21 and wheel 25 is held stationary when the pinion 20 and wheel 25 rotate at the same speed, in opposite directions, i.e. when the rollers 6 and 9 rotate at the same speed. When, however, the disc 26 rotates, due to a variation in speed between the rollers 6 and 9, a lever 31 operates one of two buttons 28 or 29, such that when the button 28 is operated the motor 32, Fig. 1, is switched on, the motor being switched off by release of the button 28, Fig. 5. When the speed of the machine being supplied with web is variable, the button 29 may be arranged to switch the motor on in the reverse direction in order to brake the replacement roll.

Title: Cathode ray tube apparatus
IPC: H04N3/20
Filed: 1962-04-27
Abstract: 991,188. Cathode-ray tube circuits. FERNSEH G.m.b.H. April 27, 1962 [April 28, 1961; Aug. 19, 1961; Sept. 9, 1961], No. 16169/62. Heading H4T. Cessation of either or both of the impulse voltages derived from the horizontal and vertical deflection means of a cathode-ray tube (CRT) is utilized to suppress the tube beam either by the application of a suitable bias to a control electrode or by interruption of the E.H.T. generator. Fig. 1 shows an example of the former in which voltages derived from the horizontal deflection coils 1 and the vertical deflection coils 4 are separately rectified by diodes 8, 9 and 10, 11 and additively combined via resistors 13, 14 to provide, between terminals 15, 18 an additional bias for transistor 16 sufficient to cut-off the latter only when both voltages are present. On the interruption of either or both of the latter transistor 16 conducts and shunts the more negative portion of the potential divider which supplies normal bias to the control grid of the CRT via terminal 17 so that the potential of the latter becomes sufficiently negative to cut-off the tube beam. Instead of deriving the control voltages directly from the horizontal and vertical deflection coils they may be derived from auxiliary coils inductively linked with the deflection coils (Fig. 1a, not shown). In another arrangement in which beam suppression is effected by the application of a positive bias to the cathode of the CRT failure of either of the scanning means operates, as in the former example, to produce a reduction in the voltage between terminals 15, 18 (Fig. 2), so that transistor 21 becomes conducting and supplies a positive voltage to the base of a normally cut-off transistor 22 which then conducts and applies a positive voltage to the cathode of the CRT via terminal 25. In this arrangement, which is stated to be especially advantageous when the CRT is a television pick-up tube, blanking pulses may be introduced in terminal 23. An arrangement which operates to interrupt the E.H.T. generator is shown in Fig. 3, the operation being that on failure of either scanning generator transistor 35 conducts causing transistor 36 to be cut-off so that the potential at point 37 is reduced below a value at which transistor 40 can continue to oscillate to provide EHT at terminal 43. In a further arrangement failure of either or both of control voltages derived by rectification of the voltages across the secondary windings of transformers 51, 52, the respective primaries of which are supplied with the-horizontal and vertical deflection voltages allows either or both diodes 66, 67 to conduct so that a negative voltage sufficient to suppress the beam is applied to the control electrode 71 of the CRT 69 which, in this embodiment comprises an image orthicon tube.
