Title: Method and circuit arrangement for safeguarded data transmission
IPC: H04L1/00
Filed: 1973-10-15
Abstract: 1424919 Data transmission; error correction LICENTIA PATENT VERWALTUNGS GmbH 15 Oct 1973 [13 Oct 1972] 47962/73 Heading H4P A forward error detecting and correcting arrangement has two stages of redundant operation on an original message. In the embodiment described check bits ml are derived from and added to the data K1, the whole being subjected to polynomial division generating a remainder which is also transmitted, after K1+m1.  At the transmitter data source 1 is connected to a first coder which computes ml redundant bits which added to K1 information bits forms blocks nl which are passed to a second coder 3 providing protection against statistically distributed errors. Blocks n1 are divided into sections K2 and the second coder calculates a remainder m2 which when added to K2 provides blocks n2 which are modulated into analogue form and transmitted. At the receiver a reverse process takes place in unit 7-9 and additionally a disturbance detector 11, described in greater detail with respect to Fig. 5 (not shown) has thresholds for weak and heavily disturbed incoming signals and emits bit wise disturbance reports to unit 12 for heavily disturbed signals. Unit 11 judges quality of analogue signals received and may operate on a bit or block basis. Unit 12 evaluates distrubances 7, 11 and controls units 7, 8 or inhibits 8, 9 if data blocks are uncorrectable. However if errors are in groups the data sync. 10 may be fed with those parts of received characters which are received without error or are correctable. In an alternative arrangement, where emission of data is always desired, output gates are not inhibited but the data sink is arranged to identify erroneous data.

In an hydraulic brake master cylinder comprising a piston axially slidable in a cylinder having a first port communicating with the brake system and a second port communicating with a reservoir, application of braking pressure causes a valve to close the second port and any residual pressure after braking causes the piston to move towards a stop member in which position the second port is opened to relieve the said residual pressure. As shown a tandem master cylinder 10 has pistons 13, 14 and ports 34, 36 communicating with first and second reservoirs, a sealing cup 27 on piston 13 forming a valve member to close the port 34 when the piston is moved forwardly and a valve 37 interrupting communication between the secondary hydraulic chamber 31 and the second reservoir. When pressure on the pedal is released piston 14 moves until a shoulder 21 engages a stopper bolt 50 and valve 37 opens communication with the reservoir to release residual pressure.
