Abstract: 1331282 Television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 7 Oct 1970 [11 Oct 1969 (2) 14 Oct 1969] 47779/70 Heading H4F [Also in Division G5] To display the information contained in a standard television signal on an m-row ncolumn luminescent element matrix (e.g. fluorescent discharge tube matrix), m equally spaced horizontal lines are selected from each television field and n equally spaced picture information signal pulses are derived from each of the m horizontal lines. For colour display each matrix element comprises a red, green and blue light source and preferably also a white light source for saturation variation. The n pulses for each selected line are derived by sampling the video signal whenever it exceeds a predetermined threshold value so that each element receives a "1" or "0" signal. Only one field is selected for display from each group of k successive fields and these selected fields may be recorded and playedback from magnetic tape before they are processed as described above. For a colour television signal each primary colour signal and the white colour signal are simultaneously sampled and preferably index pulses are added to one primary colour-signal. Before this sampling each selected line of green, blue and white colour signals may be delayed by one, two and three line periods respectively with respect to the red colour signal so that they may be successively recorded on a magnetic tape, the signals being conversely delayed after play-back to bring them back into coincidence with one another before they are sampled in respective sampling circuits. The sampling may be effected directly on the played-back signal, each row of the matrix then being scanned four times, once for each colour. Alternatively instead of using delay lines successive lines of the video signal may be selected for the red, green, blue and white colour signals, Every kth field of an NTSC signal may be recorded and upon playback converted into separate colour signals and sampled as above.

Abstract: 1,160,254. Centralized dictation systems. L. KISS. 25 Jan., 1968 [25 Oct., 1966], No. 47930/66. Heading H4K. In a system including a plurality of, e.g., dictation machines which can be allotted in turn to any one of a plurality of lines, each line has an associated relay chain in which there is one relay per machine and each relay is operable by potentials of opposite polarity applied thereto in order to connect the line to the machine, complete a self-holding circuit for itself and reduce or remove the operating potentials so as to provide a busy marking. A subscriber 1 (upper part of the Figure) is connectible via contact sets X, Y or Z to one of three dictation machines (only D2 shown), relays A and B coming up to busy the machine and allot the next one for use when this connection is complete. A calling subscriber closes his earth key in order to energize, from a low impedance 50. volt negative source RS, the first free relay in his relay chain X, Y, Z. If this is relay X, say; a speech path is cut-through by its contacts X1, X2; a holding path is completed via X4 and A2, B1; and a short circuit between similar resistors 6 and 5 is made by its contact X3 in order to mark a lead 7 extending to other such relay chains with - 25 v. whereby all other X relays are effectively busied. Contacts (not shown) of the A, B relays connect sources like RS to the leads 3C in the other relay chains so that if one of the subscribers associated therewith should call he can be connected to the second machine. The diodes D1 to D6 which isolate the holding circuits of the relays from the control wires 1C-4C may be replaced by breakcontacts. Capacitors may replace or be inserted in series with resistors R5 and R6 so as to reduce current drain. The relays are preferably of the reed type.
