Abstract: 1304050 Cathode-ray tube displays; television; transistor monostable circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 2 April 1970 [5 April 1969] 15719/70 Headings H3T H4F and H4T In an arrangement for generating signals controlling the production of a marker symbol in a television display, field frequency pulses 22, Fig. 2, of adjustable duration and derived from a generator 2, Fig. 1, supplied with field synch. pulses 21 are shaped by a square-wave generator 5 to produce variable position square-wave pulses 24 which via a gate 7 supplied with line synch. pulses 25 pass a series of these pulses 26 (26<SP>1</SP>) to a generator 8 producing pulses 27 of adjustable duration. The latter are supplied to a shaper 9 comprising three identical pulse generators 10, 11, 12 the durations of the pulse outputs of which 28, 29, 30 are controlled by a sawtooth wave 23, (23<SP>1</SP>) derived from a generator 4 supplied with the output of generator 2 the duration of the sawtooth being the same as that of the variable position pulses 24. The pulse trains 29 and 30 are then superimposed on the video signal 31 in a circuit 13 with such polarities that pulses 29 act to blank the beam of the display cathode-ray tube and pulses 30 to increase the intensity thereof so that the marker symbol which is built-up as shown in Fig. 3, comprises a black portion and a white portion each having a pointed portion as shown in Fig. 4. Thus a clear indication of a feature of interest in the display may be produced irrespective of the over all background brightness of the display. The generator 12 may be dispensed with and a polarity reversing switch employed to enable a black or white marker to be produced at will from the pulse train 29. When the pulse trains 29 and 30 are available they may be superimposed on the red and green channels of a colour television system, Fig. 9 (not shown). Fig. 5 shows the circuit of one of the three identical pulse generators 10, 11 or 12 and comprises a monostable circuit, transistors 41, 42, which are switched to the non-stable state by the positively going portion of the pulses 27, 28 or 29 the duration of which non-stable state is determined by the input sawtooth 23<SP>1</SP> acting via transistors 56 and 52 to modify the charge on the capacitor 43. When it is desired to produce a marker symbol, Fig. 8 (not shown) the pointed end of which is directed downwardly to the right (instead of to the left as in Fig. 4), the generator 10 is modified by an arrangement selected by electromagnetically operated switch means to so control the charge on capacitor 43 that the output pulse train 28 comprises negatively going pulses the durations of which increase instead of decrease (Fig. 6, not shown).

[Class 100 (ii)] [Also in Group XXXVI] A method for the production of a printing forme consists in etching away metallic parts at the same time controlling the extent of the etching sideways with or without depth control by means of a material not attacked by the etching agent, and the etching is carried out by a sulphidizing etching agent with or without an electric current, the depth or surface extent of etching being restricted by the surface or edge of a layer of zinc or cadmium. A layer of metal such as copper or tin which can be attacked by the sulphidizing etching agent, which may be an alkali sulphide or polysulphide, is coated galvanically or photographically with an image formed of zinc or cadmium. The copper or tin may be a surface on an underlayer comprising a plate of stainless steel, chromium, chromium alloy or copper lined with chromium, which after etching is made water-receptible and ink-refusing. The copper or tin is then etched away, leaving ink-receptible parts of zinc or cadmium. The zinc layer may be formed on the entire surface of the forme and the unwanted parts removed by ordinary etching. Asphalt powder may be dusted on the copper layer and melted and zinc applied into the openings in the copy and the asphalt removed. In another form, copper or tin is applied to a zinc or cadmium underlayer, and the image formed of a protecting layer on the copper or tin, which is then etched away and the resist removed, the zinc surface being made ink-refusing.
