Abstract: 1,105,337. Single sideband amplitude modulation. PHILIPS ELECTRONICS & ASSOCIATED INDUSTRIES Ltd. 15 April, 1966 [17 April, 1965], No. 16605/66. Addition to 976,235. Heading H3R. A compatible single-sideband modulating system wherein the output of a microphone 1 modulates a carrier 5 in mixer 4 the output of which is filtered to produce a single sideband signal which modulates itself in mixer 9 to produce a single sideband signal on double the frequency of the carrier 5, this signal being amplitude limited (unit 28) and modulated in unit 30 by the output of a synchronous detector 19 brought to a suitable amplitude and phase, is characterized in that a further signal is added to the main signal at 44, this further signal being derived from a single sideband suppressed carrier signal which modulates itself in mixer 38 and passes through a low-pass filter 39 to a pushpull modulator 40 supplied with twice the frequency of carrier 5 by a frequency doubler 45. It is explained that the further signal cancels certain components which would otherwise produce distortion at the receiver. In Fig. 1 the further signal is derived from a separate modulator 36 and filter 37; in a modification. Fig. 4 (not shown), the modulator 4 and filter (46) produce a suppressed carrier single sideband signal which feeds units 19 and 38 and which is combined with a carrier signal from unit 5 before passing to mixer 9.

Title: Improvements in or relating to telecommunication system
Inventor: REES FREDERICK HENRY
IPC: H04Q11/06
Filed: 1969-04-02
Abstract: 1,254,606. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. 24 March, 1970 [2 April, 1969], No. 17322/69. Headings H4K and H4R. A time division multiplex, pulse code modulation telecommunication system adapted to transmit both data and speech employs timeassigned speech interpolation for speech transmission between switching centres during heavy traffic conditions. A system is outlined in which each multiplex highway employs 32 time slots of which 30 are used for speech or data and 2 are used for TAS1 order-wire signals. Each slot comprises 8 bits and the 2 order-wire slots together transmit a 16-bit code. In a group of 4 successive cycles, two such codes are used for TASI control, one is used for synchronization and the last for normal order-wire control. During heavy traffic periods TAS1 techniques come into operation. When a speech channel is silient between speech bursts, are all zero PCM code is sent and after 4 successive cycles the speech path is broken and re-established when speech again commences. Data blocks are headed by and separated by an all one codes to avoid breaking down of the path during data transmission. During idle traffic periods the all zero codes are omitted. The switching network at each switching centre is of space-time space format and includes a plurality of junctor circuits, each of which can connect any time slot of any input channel to any time slot of any output channel. Each junctor includes first and second cyclic stores each having a storage location for each time slot, and a random access store. The locations of the first and second cyclic stores are individually associated with incoming and outgoing calls respectively. In two alternative embodiments there is a location in the random access store for each time slot. Each storage cell in one cyclic store by its time position gives the location of a random access storage cell to receive a PCM sample and the corresponding location in the other cyclic store stores the location of the random access storage cell which contains the PCM sample to be sent out to a called time at that instant. In a third embodiment the number of storage locations in the random access store equals the maximum number of simultaneous calls and both cyclic stores store an address of a random access storage cell. It is stated that PCM codes may be transmitted through exchanges not having store and forward message equipment by the use of the all ones code as a pulse stuffing device.

Abstract: 229,568. Jelley, E. E. July 22, 1924. Plates and films; printing paper, fabrics, and materials; developing; toning. - A sensitizer which may be stored and applied when required to surfaces such as paper, parchment, plaster, textile fabrics, or films such as of casein, gelatine, or albumen, which contain or have added thereto traces of halogen salts, consists of a mixture containing a soluble silver salt and one or more soluble salts of hydrazine and/or its derivatives. Several silver salts and salts of hydrazine. and its derivatives are instanced. The silver and hydrazine salts may be kept in the dry state in the required portions, separate or mixed, either loose or in tablets, so that it is only necessary to aid the required amount of water to form the sensitizer, or in solution, the sensitizing solution containing from per cent up to saturation of each of the salts. The solution is applied to any absorbent surface or to a non-absorbent surface. such as glass, porcelain, or plaster to which an absorbent layer, for example of casein, gelatine, or albumen has been added, the surface being free from reducing, oxidizing, alkaline, or sulphide compounds. Surfaces which do not contain halogen salts may first be treated with a solution for example of sodium chloride, or potassium bromide. The surfaces may be used for printing as with either self-toning or gaslight papers. When a short exposure is given the image may be developed in an alkaline solution containing for example sodium chloride and hydroxide, or di-sodium hydrogen phosphate and sodium carbonate, or certain salts of weak acids such as sodium acetate used in hot aqueous solution. The print may be toned in shades between brown and prussian blue by a solution containing potassium ferrocvanide, iron alum, and nitric acid. Copper ferricyanide and uranium ferricyanide solutions may be used for toning up to chalky red tones. Black or grey tones are obtained by bleaching with mercuric chloride and hydrochloric acid, washing, and immersing in a 5 per cent solution of sodium sulphite. The print may also be dye-toned by any of the processes used with bromide papers.
