Title: Method of and apparatus for recording television pictures on cinematograph film
Inventor: MACNAMARA TERENCE CAMERON
IPC: H04N5/84
Filed: 1958-11-26
Abstract: 870,871. Television. ASSOCIATED TELEVISION Ltd. Nov. 25, 1959 [Nov. 26, 1958], No. 38117/58. Class 40(3) In apparatus for recording television signals as pictures on a kinematograph film 7 moved intermittently through a camera 8, the speed of operation is reduced so as to allow a longer period for the pull-down operation by first recording the signals on a magnetic record carrier, e.g. in a magnetic tape recording apparatus 1, and then reproducing the signals at a slower speed than that at which they are recorded. The film recording is effected by means of a cathode-ray tube 2 the electron beam of which forms a defocused area of light on the screen and is not subject to scanning. The light from the screen is optically focused to a fine spot on the film and is scanned in the line and frame directions by mirror drums 3 and 5. Motors 4 and 6 for the drums and a motor 9 for the camera are controlled by synchronizing signals separated from the reproduced signals by synchronizing pulse separator 10. Lens discs or drums may be used in place of mirror drums. Since the reproduced signals are of reduced bandwidth they may be transmitted over a relative narrow bandwidth line, e.g. a telephone line, to a remotely situated film recorder.

Title: Method of distinguishing traffic radio areas
IPC: G08G1/09
Filed: 1973-08-17
Abstract: 1418325 Radio signalling BLAUPUNKT-WERKE GmbH 17 Aug 1973 [19 Aug 1972] 39057/73 Heading H4L A radio transmitter transmits information, e.g. traffic news on a subcarrier of above audiofrequency, which in turn modulates a main carrier, the subcarrier being amplitude modulated with a frequency outside the audio range which is indicative of the transmitter. As described the transmitter is included in a system in which a plurality of such transmitters are each allotted to a particular traffic area identified by a sub-audible frequency which modulates the subcarrier. The lowest frequency of the range of sub-audio frequencies is a message identification signal indicating the beginning and end of traffic information. At a co-operating receiver, the subcarrier is selected and supplied to a recognition circuit 1, which controls a selfseeking tuner and indicates that a traffic signal is being received, and is demodulated, the resulting sub-audio frequency f K  being supplied via a Schmitt trigger 2 which converts it into a rectangular wave, to a monostable 3 which converts it into pulses of constant duration. These pulses are integrated at 4 so that a voltage U K  proportional to the frequency f K  is supplied via switch S to an indicating device 5 which includes a scale 7 composed of luminous elements 6. This scale carries markings for the traffic radio areas in addition to a normal frequency scale. Thus if the voltage U K  is applied. instead of a tuning voltage U Abst  of an electronically tuned receiver, the element 6 corresponding to the frequency f K  of a traffic area will light up. Push buttons 8 may be operated so that only transmitters in particular areas will be received. The message identification signal is selected by a filter 9 and may be arranged to switch on and off a recording device.

An information store comprises thin magnetic film elements 3 deposited on conductive substrates 2 and covered by row conductors 12 which produce magnetic fields to switch the elements from the easy to the hard directions and column conductors 13 to supply a second magnetic field which determines . the easy direction taken up by the element on removal of the fields. In the embodiment described a word organized array comprises a ground plate 1 which acts as a return conductor on which are mounted the substrates 2 insulated from ground plate 1 by an insulating layer 4. Sense windings 11 are separated from the elements by an insulating layer (not shown) and may be printed circuit wiring. The row and column conductors 12 and 13 are similarly located above the sense windings 11. The conductors are slotted to reduce eddy current losses and reduce the shielding of the elements from the upper conductors by the lower conductors. The substrates 2 may be adjustably located on the ground plate 1 by pins 27 (Fig. 2) and the whole assembly may be held by nuts 26. It is stated that the use of conducting substrates 2 improves the capacitive coupling between the conductors and the ground plate 1. The spacing between the sense winding 11 and elements 3 is about one fifth of the spacing between the other conductors 12, 13 and the elements 3 to reduce the noise induced in the sense windings 11 by currents in the other conductors 12, 13. Suitable insulating materials are described and photo etching and/ or vapour deposition may be used to produce the elements 3 and conductors 11, 12, 13. A constant bias current may be carried in the column windings 13 to return the elements to the " zero " state unless a " one " signal is applied. The conductors may be selected by linear selection (Fig. 4, not shown). The ground plate may be recessed to accommodate the substrates.
