Title: Improvements to Ciphering and Deciphering Systems.
IPC: H04L9/00
Filed: 1968-11-21
Abstract: 1,183,689. Digital transmission systems. INTERNATIONAL STANDARD ELECTRIC CORP. 21 Nov., 1968 [29 Nov., 1967], No. 55318/68. Heading H4P. A programme-controlled store-and-forward telegraph exchange includes a number of ciphering and deciphering units which are assigned to incoming and outgoing lines as required. Associated with each line is a respective message area in central store and also a cipher area which stores cipher information, i.e. the state to which the assigned ciphering or deciphering unit's key generator must be set prior to ciphering or deciphering a message relating to the line. In a first embodiment, the incoming and outgoing lines and the lines to and from the ciphering and deciphering units are all connected to a line-scanner. Messages received or to be transmitted by the exchange are stored in the store in known manner. If a received message, which has been assembled in a message area, is in ciphered form it must be deciphered to determine its address in order to route it to the required destination and reciphered before forwarding it. The received message is passed to a deciphering waiting area in the store. When the scanner subsequently detects a free deciphering unit that unit is assigned to the message in the waiting area. The cipher information relevant to the incoming line on which the message was received now sets the assigned unit's key generator to the correct initial state and the message is passed to the unit and deciphered. When during scanning the scanner detects that the deciphering unit has deciphered a message, the message is passed to a record area in the store, and the state that the decipher key generator has reached is placed in the cipher area. The address of the message is now determined and an indication of the appropriate outgoing line stored. The message is placed in a ciphering waiting area. When the scanner detects a free ciphering unit, if there is a message to be ciphered the cipher information relevant to the outgoing line sets up the ciphering unit's key generator and the message is then ciphered. Subsequently, during the scanning, the ciphered message is passed to a ciphered message waiting area and the state of the key generator placed in the cipher area. When the scanner determines that the required output line is free, the ciphered message is transferred to the relevant message area and passed from it to the line during subsequent scans. Instead of being connected to the scanner, the ciphering and deciphering units may be connected either directly or via a multiplexer as peripherals to the processor which controls the exchange operations.

Abstract: 1,244,617. Thermal storage heaters. ACCESSAIR S.A. 27 Nov., 1968 [27 Nov., 1967], No. 56259/68. Heading F4U. In a storage space heater of the type whose thermal reservoir discharges heat on a change of phase, the reservoir is charged indirectly by a stream of air which has been passed over an electric heating element. In a heater of the type in which a blower circulates air in a closed circuit through the reservoir and within a heater casing during discharge, the circulation is maintained, and an electric heater in the circuit is switched on, for the charging operation. If a heat exchanger is located in the air stream for the extraction of heat from the heater, the exchanger may be pivoted out of the air stream during charging. In a heater of the type in which ambient air is passed in contact with the reservoir by a fan, the fan casing or a flap valve is pivoted to create a closed air circuit within the heater for the charging operation. Where a pivoted fan casing is provided, the arrangement may be such that in intermediate casing positions part of the fan air flow by-passes the reservoir. Heaters of the type which heat ambient air may be located in a partition wall to serve two rooms, or may be located beneath the floor of a room, ambient air being drawn from and passed to the room through the floor.

Abstract: 1464533 Re-arranging data BRITISH BROADCASTING CORP 11 March 1974 [11 Dec 1972] 57035/72 Heading G4C [Also in Division H4] Storage apparatus for re-arranging data in the form of blocks e.g. sequential to interlace (or vice versa) conversion of television signals wherein each block comprises one or more lines, comprises a plurality of storage devices (e.g. line stores) connected in cascade between input and output terminals and associated with switches S 0 -S 5  controlled to selectively connect each storage device either to the adjacent device or to one of the terminals (e.g. the input terminal) or with its input coupled to its output in a recirculating mode. With five line stores as shown in Fig. 1 a sequentially scanned eleven line television signal may be converted into an interlaced scanned signal. The line stores may comprise shift-registers or recirculating delay lines. For a 625-line picture since only 576 active lines need storage 288 line stores suffice for the sequential-interlace conversion. Alternatively since 576=2<SP>6</SP>.3<SP>2</SP> the conversion may comprise 6+2 operations in cascade which reduces the number of storage devices required i.e. the total storage of 288 active lines may be effected in ten storage devices namely 2 of 1, 1 of 2, 1 of 4, 1 of 8, 1 of 16, 2 of 32 and 2 of 96 active lines. Two basic operations are effected namely a P2n permutation (1 2 3 4) to (1 3 2 4) on four blocks of data each containing n lines and a P3n permutation (1 2 3 4 5 6) to (1 3 5 2 4 6) or (1 4 2 5 3 6) on six blocks of data each containing n lines. The first permutation of four blocks may be effected using one n-line store and the switching arrangement shown in Figs. 2 and 3, and the second permutation on six blocks may be effected using two n-line stores and a switching arrangement as shown in Fig. 4. A 625-line conversion is described from sequential-to-interlace by cascading eight stages in the sequence P2 1 , P2 2 , P2 4 , P2 8 , P2 16 , P3 32 , P3 96  and P2 1 .

[Also in Division H4] In a system for electrically firing an explosive charge below a volume of liquid to generate seismic energy, the charge is located in the nose portion of a cartridge body having nose and head terminations, that end of the charge closer to the cartridge head is connected to a conducting element enclosed by the cartridge body part comprised between the head and the charge, the other end of the charge is connected through a second conducting element, at least partly external to the cartridge, to a third conducting element, and a current source is connected indirectly to the first and third conducting elements. In the Fig. 3 system the cartridge comprises electrically insulating body 7 with a head 8 which seats against member 2 to position the cartridge in relation to loading tube 1. The charge is contained in an insulating tube 11 with conducting end members 13, 14 which are linked by wire 12. Body 7 is provided with an external conductive coating 16 at the nose and encloses a tube 17 having a conductive coating 18. The firing circuit for exploding wire 12 to detonate the charge comprises electrode 3, water inside loading tube 1, coating 18, end member 13, wire 12, end member 14, coating 16, water surrounding the cartridge, and a return electrode (not shown). Modifications are described in which (a) tube 17 and coating 18 are replaced by an internal conductive coating on body 7, which coating may or may not make direct electrical contact with an extension of electrode 3; and (b) a conducting charge is used so that wire 12 is not required. In the Fig. 6 system the charge comprises a stable pulverulent component 23 (e.g. ammonium nitrate and/or aluminium powder) and a glass or plastic encapsulated stable liquid component 24 (e.g. nitrobenzene or dinitrotoluene). Water pressure forces the cartridge through the loading tube and then causes spiked sliding member 27 to break the capsule 24. The firing circuit comprises electrode 3, water in the loading tube, conductive coating 15, a pair of wires 25 which link coating 15 to a stud 26 traversing the cartridge nose, stud 26, and a yoke-shaped return electrode 33. Instead of pulverulent charge component 23, one or more encapsulated liquid components may be used.
