Patent EP-0039150-B1 (EP)
IPC: H04L7/04
Filed: 1981-04-07
Granted: 1984-07-11
Abstract: Frame information is recovered from a stream of binary data formed at a transmitter (1) from a block of m xn information bits comprising m groups of n bits plus m parity bits, one for each said group of n bits, these parity bits having then been scrambled by performing an exclusive-OR operation in a gate (5) on each parity bit with a respective bit of an m-bit parity scrambling code, said block of bits together with the scrambled parity bits forming a frame for transmission over a transmission link (3). At a receiver (2) new parity bits are produced in a parity bit generator (9) at the incoming bit rate from the incoming stream of binary data by forming a new parity bit from each successive moving group of n +1 incoming bits. The new parity bits are cyclically distributed to n + 1 m-bit shift registers (10,11,12,13), and a framing signal is produced when one of the shift registers (10,11,12,13) holdsm bits substantially corresponding to the m bits of the parity scrambling code.

Abstract: The invention provides a die assembly comprising a nozzle and at least one mandrel which defines with the nozzle an annular die orifice. The nozzle has a longitudinally extending stem terminating in the sleeve, the mandrel being located coaxially within the sleeve and coupled to the stem of the nozzle by an axially extending screw threaded coupling. The mandrel includes an internal flow passage having an inlet positioned to receive thermoplastic material from a supply passage extending along the nozzle and an outlet positioned to deliver the material to an annular distribution chamber defined by the opposing surfaces of the mandrel and the sleeve. The distribution chamber provides an uninterrupted annular flow path extending from the outlet to the die orifice, thereby avoiding the disadvantage of imperfect material distribution. For the production of multiple-walled tubing, a plurality of die stages coupled together in coaxial relationships are provided, the die components being so coupled by axially extending screw threaded couplings so positioned as not to interfere with the flow of plastic materials.

Abstract: In order to provide higher efficiency of security in sync suppression scrambling of subscription TV signals, the signals are encoded with a timing pulse having a selected time delay relationship with the suppressed horizontal sync intervals of the TV signals. The timing can be implemented digitally by selecting a plurality (e.g., 12) of different timings. The timing can also be dynamically varied. The TV signals are descrambled by restoring the sync pulses at only those receiving stations authorized to receive the premium subscription programming which have circuits for generating restoring pulses with the selected time relationship upon reception of the timing signals. Accordingly, the use of unauthorized descramblers, which are insensitive to the timing signals or do not provide the restoring pulses in proper time relationship, is discouraged.
