Abstract: 1289317 Electromagnetic mixing GENERAL ELECTRIC CO Ltd 13 Jan 1971 [18 Nov 1969] 56363/69 Heading B1C [Also in Divisions C1 and F4] In a method of manufacturing glass in which the heating is achieved by passing an electric current through the glass-forming constituents, the liquid glass flow is modified by subjecting the molten glass to a magnetic field the the flux of which is transverse to the direction of the electric current.

Title: Detection of induction pulse cancellation errors
IPC: H04N5/217
Filed: 1970-11-25
Abstract: 1328095 Cathode-ray tube circuits BRITISH BROADCASTING CORP 25 Nov 1970 [4 Dec 1969] 59316/69 Heading H4T An error signal is produced dependent upon the difference (if any) between imperfectly cancelled induction pulses (produced in the output signal of a television camera tube during line fly-back intervals) and the output signal amplitude outside the line fly-back intervals but when video information is not present (e.g. during field blanking periods), such error signal being employed to adjust a parameter (amplitude, width or duration) of the cancelling pulses. Fig. 1 shows the arrangement for carrying out the invention in which the output signals from a television camera, the signals including the induced pulses due to the line fly-back together with added cancellation pulses, are fed via a variable gain amplifier 11 to a D.C. clamp 12 the output of which is supplied via a polarity reversing switch 13 to an integrator 14 and thence to a sample and hold circuit 18. Fig. 2, shows the various waveforms operative in the circuit of Fig. 1. In operation, an activate pulse 31 occurring during alternate field blanking periods together with line drive pulses 30 control a cycling waveform generator 15 producing waveform 32 which switches the gain of amplifier 11 between two values (one of which may be zero so that the amplifier may be replaced by a switch) as shown in waveform 33 and synchronously operates the polarity reversing switch 13 for the period determined by startstop pulses 36, 37 derived from a sequence control, 22 also controlled by pulses 30 and 31. If the induced pulses have been corrected compensated by the added cancellation pulses variation of the gain of amplifier 11 will not alter the voltage difference between the black level and the average value during the clamp pulse duration since such difference is zero. If, however, compensation is not correct such voltage difference will vary with change in amplifier gain so that the output of the clamp will vary as shown by waveform 34 from the D.C. clamping voltage 35. Switch 13 then inverts alternate half cycles to produce waveform 38 which, when integrated in 14, produces the waveform 40, the latter, after the occurance of a stop pulse 37, being sampled by a pulse 41 to produce the error signal 44. The error signal may then be utilized to control the amplitude of the cancellation pulses which are added to the camera output signal and the video signal on line 23 utilized in normal manner but with the addition of blanking during appropriate intervals to remove perturbations caused, e.g. by the changes of gain of amplifier 11. Alternatively, the circuit of Fig. 1 may be employed in a "side chain" arrangement (Fig. 3, not shown). The error signal output may also be displayed on a meter.

Title: Integrating amplifier circuits

Abstract: 1337275 Integrating amplifiers TAYLOR SERVOMEX Ltd and A J BORER 4 June 1971 [5 June 1970] 27283/70 Heading G4G An integrating amplifier A3, Fig. 1, is fed from a pulse-width modulating circuit A1, A2 through a switch S which is open during the space periods of the modulated signal. Integration proceeds only during the mark periods of the modulated signal. During the space periods, the input of the integrator floats in potential and balances itself with zero output increment thereby eliminating the effect of offset during these periods. If the average mark/space ratio is made very small, the error in the output signal due to offset may be made correspondingly small. The ramp generator of Fig. 3 has three inputs 1, 1<SP>1</SP>, 1<SP>11</SP> to which signals representative of temperature in three ranges may be applied. The output of amplifier A1 is connected to triggers VT1, VT2 which control current sources VT3, VT4. When turned on, the latter feed respectively a current of the order of milliamps to the input of A1 and a signal of the order of microamps to the input of integrator A3 through the field-effect transistor VT5. When VT4 is turned off, the diode VR3 is reversed biased whereby the input to the integrator floats in potential as required. The circuit is linearized by means of feedback from the output 2 through network R28, R22, R29. To set up the circuit R8 is adjusted such that the output of A1 is constant in the absence of any input, and R17 is adjusted for a suitable ratio between the collector currents of VT3, VT4 such that the rate of change of output at terminal 2 is correctly related to the inputs at terminls 1, 1<SP>1</SP>, 1<SP>11</SP>.

Abstract: 1343812 Altering physical properties; stretching; making wire BRITISH ROPES Ltd 29 June 1972 [29 March 1971] 8097/71 Headings B3V B3A and B3E The mechanical and/or physical properties of a flexible elongate metal element are improved by continuously raising the temperature of the element to a given value while subjecting it to a continuously increasing tension, and, the tension having reached a given value, maintaining the tension while cooling the element rapidly. A wire, strand or rope, hereinafter referred to as wire 1, is fed by rolls 3, 4, Fig. 1, to the top of a heated cone 5. The tension in the wire is increased by helically guiding the wire down the cone with grooves 8 in a casing 9, the wire being heated by the cone so as to attain a temperature of from 200-400‹ C. when it reaches skirt 7. Finally the wire is quenched by water sprays 11, 12 and coiled on a wheel 10. In another embodiment the groove 8 is replaced by circumferentially grooved rollers spaced around the cone with their axes parallel with the cone surface. In another embodiment, Fig. 3, a length of wire 1 is locked between capstans 24, 30 over grooved rollers 28. The length of wire is then subjected simultaneously to increasing tension and temperature by respectively raising a pivoted arm 27 by ram 37, via wedges 38, 39 and link 40, and energizing heating devices in the rollers 28. As soon as the required tension and temperature have been reached, the length of wire, still under tension, is wound by the capstan 30 and cooled by spray 31. When the treated length has been wound on, the arm 27 is lowered and the new length of wire between the capstans is ready to be treated.
