Title: Broadcasting encrypted signals
Inventor: SERPELL STEPHEN CHARLES
IPC: H04K1/02
Filed: 1983-04-14
Granted: 1985-11-07
Abstract: Binary signals for broadcasting are encrypted by a pseudorandom bit-stream generated from a secret key and an initialisation bit-stream. The initialisation stream is multiplexed, broadcast, recovered at the receiver and used to regenerate the pseuodorandom stream for decrypting. The multiplexing ensures synchronisation. Each pseudorandomiser, at transmitter and receiver, has a ciphering engine 11 containing the key 10. 64-bit words are pseudorandomised and fed back from output register 13, and the pseudorandomised words are sent bit-by-bit on line 15 as the encryption stream. Random number generator 16 produces an initialisation stream which is formed into words by initialisation register 17 and periodically transferred to input register 12 by control codes from unit 22. Control codes, on line 17, and initialisation stream, on line 18, are multiplexed and broadcast. Each receiver separates the control pulses and initialisation stream whereby register 17 obtains initialisation words and microprocessor 11 regenerates the description stream.

Title: Cable joint protection
Inventor: POKOJNY RUDOLF
IPC: H02G15/18
Filed: 1983-05-03
Granted: 1989-02-23
Abstract: This invention relates to the mechanical and environmental protection of cable joints, especially in power or other current-carrying cables. Disclosed is a recoverable sleeve which conforms closely to the cable joint, and a liner which bridges the joint and comprises a plurality of elongate elements assembled into a sheet. Flexible means is provided for holding the elements in a side-by-side arrangement and allowing the separation between the elements to vary to allow the liner to conform to the profile of the cable joint. Such flexible means may extend across the element and provide a water vapour barrier. Disclosed also is a method of protecting a cable joint utilizing the sleeve and liner. Where the cables to be jointed have metal armor, screen and/or shielding, the elements may be fabricated from metal or metal alloy and may then provide both armoring and a fault current path across the joint. Use of these more closely conforming joint case assemblies improves heat transfer and reduces the overall size of the joint.
Patent DE-3382100-D1 (DE)
Inventor: RUTA JOSEPH W
IPC: H02H3/44
Filed: 1983-10-03
Granted: 1991-02-07
Abstract: A control circuit is provided for operating a circuit interrupter in response to overcurrent in an alternating-current line in which the circuit interrupter is located. The control circuit includes a transducer for producing output current proportional to the current in the line. A time-current trip signal generator circuit responds to output current representative of moderate overcurrent in the line by producing a trip signal after the passage of a time period that is inversely related to the overcurrent. An instantaneous trip signal generator circuit produces a trip signal after a predetermined time interval in response to output current between a minimum and maximum magnitude and increasing at a rate greater than a selected rate, which conditions indicate the presence of high overcurrent in the line. In the preferred arrangement, the predetermined time interval is measured from the time that the rate of change of the current exceeds a predetermined rate. Accordingly, when the onset of high overcurrent is detected, the current is interrupted with a minimum possible delay while substantially reducing undesired response to noise and false signals.
