Filed: 1971-09-03
Abstract: 1366088 Automatic exchange systems TELEPHON - UNO TELEGRAPHEN - FABRIKS AG KAPSCH & SOHNE 3 Sept 1971 [3 Sept 1970] 41303/71 Heading H4K A subscriber's line subject to earth leakage is identified by a lamp connected to the line at the exchange end and the fault is notified to a central control by virtue of the resistance change in a photoresistor which is coupled to a plurality of such lamps. Under normal conditions line relay R responds to a line loop and is followed up by T and F when a control circuit acknowledges the service request by marking the C- wire. R relapses. On an incoming call T and F are similarly brought up by a mark on the C- wire. At the end of the call T falls back but, if the handset is not replaced, R re-energizes and howler tone is reverted from source Bes. Relay F holds for up to 120 n.sec. following relapses of R, when T is inoperative, by virtue of the CR circuit Wi1, C, this arrangement being effective to cause howler tone to be reverted in the event that the subscriber commences dialling prematurely. Should earth leakage be present during a call a feed relay (not shown) drops thereby releasing T and, after a delay, F whereby R cannot come up. This is also the position when the line is unlooped between calls. In either case the lamp L is now in series between earth E (shown as being applied to the a wire) and negative battery for a time sufficiently long that it lights up and thus via photoresistor LDR informs control that an earth fault has occurred.

Abstract: 1,183,589. Magnetic printing; colour printing. STANDARD TELEPHONES & CABLES Ltd. 21 Sept., 1967, No. 42934/67. Headings B6C and B6F. [Also in Divisions G2 and G5] A device for converting an informationbearing signal into a coloured display image (see Division G5) may also provide a permanent coloured record. As described (i) an electrostatic or magnetic pattern is applied to a printing surface; (ii) the pattern is developed by applying a printing powder thereto; and (iii) the powder pattern is applied by conventional non-percussive printing machine techniques to a special record surface, which comprises an array of zones, each zone comprising sub-zones of contrasting colours, such that certain of the sub-zones are obscured: the unobscured sub-zones form in combination the desired coloured pattern. The term " colour " includes black or white. Forming the change pattern.-The pattern is applied to the printing surface by a recording head assembly of the magnetic type as described in Specification 1,052,543 or in Specification 1,183,590 or as described below. Printing equipment.-A non-percussive printing machine drum as described in Specification 1,020,900 may be used. Alternatively, the display arrangement of Fig. 4 may be adapted for printing. It comprises a band 17 moving around rollers 8; 13 is the recording head assembly, and the printing powder is applied by means 20 e.g. as disclosed in Specification 1,020,900. Alternatively, the magnetic printing apparatus described in Sepcification 1,052,543 may be used to form a powder pattern. In this embodiment, Figs. 6A, 6B, the display surface comprises a white background 34 with black areas 29 and overlies a magnetic backplate 4 such that areas 29 lie between posts 31, 30 and 32, 33 respectively. Two such areas 29 associated with four posts 30-33 constitute a magnetizable " bit " 36. Thus by magnetizing the areas such that a white powder covers the areas 29 the " bit " 36 is totally white; but by magnetizing the areas lying between posts 31, 32 and 33, 30 respectively, the black areas 29 are presented. The " bits " 36 in combination form an image, e.g. the figure " 2 " which can then be printed on to the special record surface. The record surface may alternatively be coated (see Fig. 5) with an array of groups 27 of bands 24-26 of contrasting colours. Transient display and permanent record facilities, operated by a common input signal, may be provided in the same machine, the paper feed of the latter being rendered operative only when desired.
