Filed: 1953-02-12
Abstract: 727,842. Pulse modulation circuits. MULLIN, J. T. Feb. 12, 1953 [Feb. 18, 1952], No. 3932/53. Class 40 (5). [Also in Group XL (b)] In apparatus for recording television signals on a medium, such as magnetic tape or photographic film (see Group XL (b) ), a plurality of pulse modulators each controlling an associated recording head sample the signal in sequence whereby the signal is translated into a plurality of amplitude modulated pulse trains and recorded on a like plurality of parallel tracks across the medium. The sampling pulses are derived from a timing wave which is also recorded on a separate track and serves in reproduction to control a corresponding pulse demodulation and recombination of the " played-back signals to re-establish the original television signal. The sampling pulses employed in any one modulator alternate in polarity whereby the signal modulated pulses from the modulator likewise alternate in polarity. The pulse demodulators include a storage stage prior to the pulse demodulator proper which allows for misalignment of the pick-up head with respect to the timing wave head. The pulse demodulators form the subject of Specification 730,997. Pulse modulator, Fig. 4. Timing waves in the form of rectangular signals at 165 kc. are applied through amplifier 85 to transformer 87 where they are differentiated to produce alternate positive and negative pulses of approximately one-tenth micro-second duration. The transformer comprises two centre-tapped secondary windings 91, 911 which are connected through oppositely poled rectifiers 94 and 94<SP>1</SP> respectively to an output transformer 93. The television signals are applied at 9. The potential of source 96 at least equals the maximum potential of the television signals. The pulsesrender the rectifier conducting to effect connection alternately to the upper and lower end of transformer 93 whereby the output applied through amplifier 105 and cathode follower 109 consists of a train of pulses alternating in polarity and each proportional in amplitude of the video signal at the instance of its occurrence. Integrating network 101, 103 modifies the pulses in shape and renders them more suitable for recording.

Title: Improvements in or relating to cinematograph colour films bearing a sound record
IPC: G03C7/04
Filed: 1933-02-11
Abstract: 414,761. Combined sound and picture films. DUFAYCOLOR, Ltd., and BONAMICO, C., 19, New Bridge Street, London. Feb. 11, 1933, No. 4266. [Class 40 (ii).] A method for the manufacture of a film base for use in the production of combined sound and kinematograph films having the pictures in natural colours comprises first applying a multi-colour screen to the whole width of the screen and then a resist material to that portion only of the film of which it is desired to retain the colours, and then decolourizing that portion of the film not protected by the resist material in order to provide an uncoloured sound track. Alternatively, in the production of a screen having three or more colours, the resist material is applied over the picture portion only, after the screen, except for the last colour, has been applied across the whole width of the film so that the sound track on the finished film may be coloured throughout in a single colour. The film may be provided with a colour screen as described in Specification 322,432, [Class 98 (ii)], and a protective coating of greasy ink is then applied over the whole film except for the narrow strip to constitute the sound strip. The film is passed through a bath comprising caustic potash in a mixture of alcohol, acetone and water to remove the dyes from the sound track portion, and through a bath of benzene to remove the greasy ink. In a modification, green and red lines are first formed on the film as described in Specification 322,432, and the surface is printed with fine parallel lines of greasy ink which extend at an angle to the colour lines but do not extend over the sound track portion. The film is then bleached to remove the dye from between the ink lines and also from the sound track portion. The bleached spaces are then dyed violet and the ink lines removed. The film base may be of considerable width and provided with a number of sound tracks so that it may be subsequently cut into films of the desired width. Specification 356,817 also is referred to.

Patent GB-163462-A (GB)
Title: Improvements in wireless communication
IPC: H03D3/24
Filed: 1920-02-17
Abstract: 163,462. Eccles, W. H., and Vincent, J. H. Feb. 17, 1920. Heterodyne receiving systems; modulating systems and apparatus.-Wireless signals are transmitted as minute variations in the frequency of electromagnetic waves, and at the receiving station affect an indicating circuit which is under the joint influence of the received waves and of a local oscillation generator of approximately the same frequency. The deflexions of the indicator are shown as ordinates in the curve of Fig. 1, in which the abscissµ represent frequencies of the transmitted wave. Between the points B, E (at both of which the difference in frequency between the transmitted wave and the locally-generated oscillations is less than an audible frequency) the indicator reading shows sudden changes, as the transmitted frequency approaches closely the local frequency, so that by working on any one of the parts BC, CD, or DE of the curve, the signals may be read. Fig. 2 shows the receiving circuits. The incoming waves may be amplified at A and affect a circuit N, C which is also influenced by the circuit of a local oscillator g. A detector D and indicator I are connected across the condenser C. The normal frequency of the oscillators at both stations may be kept constant by means described in the Proceedings of the Royal Society, Series A, Vol. 96, pages 455-465. When an arc oscillator is employed at the transmitter, a small receiving station arranged at or near the transmitter, is provided with a constant-frequency valve generator of the kind described in the paper referred to, and the arc circuit is adjusted by hand to keep it in tune. For signalling, the frequency of an arc generator is varied by variation of the inductance or capacity, or if a valve generator is used the voltage on the filament, grid, or anode may be varied. Instead of merely changing the frequency, signals may be sent by interrupted radiation, provided that the frequency radiated falls within the range B, E'of the curve of Fig. 1. For telephony, any means may be employed for varying the frequency emitted by means of voice currents, a telephone receiver being used as the indicator I. One of the stations may be tuned to a multiple of the frequency of the other station.
