Title: Method and apparatus for encoded messages transmission
IPC: H04L9/12
Filed: 1971-12-07
Abstract: 1379740 Digital transmission; ciphering systems GRETAG AG 7 Dec 1971 [8 Dec 1970] 56849/71 Heading H4P A message is ciphered by mixing clear text with the output from a ciphered pulse generator and a term derived from date and time. An identical generator is provided at the receiver for deciphering. As the initial state of the pulse generator is continually reset the commencing position of the generator is independent of any data supplied earlier. In a preferred embodiment a clock oscillator is used as the derived term source and synchronizing is performed between transmitter and receiver. A non- secret supplementary code is envisaged but is not particularly described in the Specification. An information source, e.g. a teleprinter 9, is connected to a transmission link 148, 148<SP>1</SP> through a mixer 8 which dependent on direction of transmission, adds/subtracts cipher sequences from generator 5 which has a long cycle and may comprise a number of storage units connectible in dependence on a secret code. Generator 5 is connected to a sync. stage 6 and has inputs from a date-time store 1, further store 2, and a mod-2 mixer 18, receiving in turn, output from a cipher store 3. The date-time store provides an output for example once per second representative of, say, date and time, and store 2 provides individual subscribers' addresses where a number of stations are connected into a system. Store 1 may additionally include a pseudorandom generator (16), Fig. 2 (not shown), providing a supplementary code which may also be supplied to mixer 18. In order to maintain sync. it is necessary for the sequence to be interrupted once per cycle for this to be effected. Sync. stage 6 comprises time comparison means 61, time difference store 62 and OR 63 connected through a time correcting means 4 feeding into date-time store 1. The time difference between a received signal and signals produced by generator 5 or a signal produced by the date-time store is measurable at 61 through a switch 23. The time difference may be utilised for resetting a receiver's own clock from unit 61 and this value may be stored in 62 which is cancelled at the end of a message. Store 3 may comprise a random access memory and/or may be connected to store 1 or 2 for further varying the cipher arrangement. The mixer 18 output is dependent on a secret code, date-time code, plus possible supplementary code, hence another subscriber having an identical generator commencing at the same position can decipher messages by means of a similar mixer 8. A suitable cipher generator is described in Specification 1,364,518. The timing clock which is incorporated in unit 1 may embrace a crystal oscillator and frequency divider which provides date-time information. Information from stores 1, 2 is supplied serially which necessitates serial/parallel conversion in (22), (26), Fig. 2, not shown. A separate synchronizing sequence sent at bit rate may be checked at a receiver by a generator which runs at a multiple of bit rate.

Title: Disc-brake, especially for industrial use
IPC: F16D65/18
Filed: 1967-12-28
Abstract: 1,208,317. Disc brakes. SOC. ANON. FRANCAISE DU FERODO. 28 Dec., 1967 [29 Dec.; 1966], No. 58926/67. Heading F2E. A spring-applied, electromagnetically released, disc brake having automatic adjustment for lining wear comprises a disc 10 (Figs. 1 and 2) between a pair of brake shoes 14A, 14B, each shoe being pivotally supported by a respective pair of parallel plates 22 constituting levers 21A, 21B. The levers are each medially supported at swivel joints 102 (Fig. 3), by a pillar 101A or 101B attached to a sole plate 16, the pillars being urged toward one another by a spring 40 comprising a stack of Belleville washers to apply the brake, and are movable apart by the energizing of an electromagnet 29. A yoke 28 of the magnet is fixed to the pillar 101B and hence to the sole plate 16, while the armature 30 is fixed via a rod 112 and a swivel joint 111 to the pillar 101A. A lug 131 (Fig. 5) of each shoe is pivotal, with play, on a rod 115, which is attached to a lug fixed to the sole plate. To automatically adjust for wear in the brake linings 11A, 11B there is provided a trapezoid or wedge-shaped block 46 (shown dotted in Fig. 2), which is freely supported between two parallel rods 25A, 25B, each of which is fixed between a respective pair of plates 22 of the levers, and the block is slidable by its own weight between the levers 21A, 21B. A freewheel or ratchet 45 (Fig. 1) is mounted coaxially on a shaft 23B (Figs. 1 and 2) its inner cage being fixed on this shaft, for movement with lever 21B also clamped to the shaft. The outer cage is rigidly fixed to two arms 117 connected together by a sleeve 118. The sleeve is connected by a tie-rod 119 to a cross-member 120 (Fig. 2) joining the end-plates 22 of the other lever 21A. During movement of armature 30 to release the disc 10, the levers 21A, 21B fixed to the inner and outer cage of the freewheel respectively, pivot about shafts 23A, 23B and liberate the block 46 which slides due to its weight on the surface of end-plates 22 in order to maintain contact with the shafts 25A, 25B. Thus the levers 21A, 21B are maintained wider apart at their lower ends and closer at their upper ends, their change in spacing corresponding automatically to wear in the linings recorded during the previous braking operation. The brake lining is bonded to a base-plate held in the brake shoe housing 130 by magnetic studs.

Abstract: 1329839 Substation equipment PIONEER ELECTRONIC CORP 29 Dec 1970 [29 Dec 1969] 61593/70 Heading H4K A telephone answering machine is exclusively connected to any one of a plurality of telephone lines in response to the occurrence of ringing current thereon by means of a first relay and the other lines are then prevented from accessing the machine by means of a second relay. As shown ringing current on say line L1 is rectified and caused to build up a charge on capacitor C3 until Zener diode D1 breaks-down so turning-on thyristor D2. A first relay Y1 comes up over its "a" winding to connect the line L1 to the answering machine AF and to open the priority relay contact chain y13, y23, y33 thereby causing second relay X2 to fall back. In so doing, it opens contacts x21 and similar contacts associated with the other lines so as to render ineffective any subsequent ringing current on these other lines and also opens contact x20. Consequently timing capacitor C5 commences to charge thus temporarily (e.g. for 10 secs.) maintaining transistor Tr2 conductive and thereby causing Y1 to hold over its "b" winding. Within this ten seconds timing period AF should respond, to loop the line and so bring up X1 which then provides an alternative holding path for Y1 "b" via x11. When C5 is fully charged Tr1 turns-on and Tr2 turns-off. At the end of the answering period (about 1 minute) the line is unlooped by AF to drop X1 and simultaneously therewith Y1. Consequently at the end of the charging period of C4, Tr2 switches-on again, Tr1 turns-off, X2 comes up and the apparatus is ready to receive a new call. In the event of simultaneous calls, priority goes to whichever Y relay is the first to operate.
