Title: Improvements to joints for multi-stranded anchoring cables
Inventor: FUENTE CARLOS DE LA
IPC: E04C5/08
Filed: 1984-09-20
Abstract: The invention relates to an anchoring cable having n strands 5, n being a whole number greater than 1, characterised in that it comprises n elementary joints 7 each linking up two strand ends 5 belonging respectively to the two lengths of cable to be joined, each of these elementary joints being designed in such a way that it may be broken by simply applying, between its two ends, a tension which is greater than that which this elementary joint is intended to normally be subjected to in service, but which is lower than the breaking tension of the corresponding strand. Such joints are advantageously used on cables intended for the temporary anchoring of structures to solid blocks.

Title: Video signal noise-removal circuit
Inventor: GILLET CLAUDE
IPC: H04N5/21
Filed: 1984-09-25
Abstract: It enables the noise to be reduced by acting on the high-frequency spectrum of the video signal. It comprises a first path 1 allowing through only the low-frequency component of the input signal VE, and a second path 2A, 2B allowing through only the high-frequency component of the input signal whose voltage does not lie between two specified values + VA, - VB, preferably centred around the zero volt potential. The second path comprises voltage selection means 3A, 3B which only transmit the high-frequency component above the positive value of adjustment threshold + VA and below the negative value of adjustment threshold - VB. The outputs of the two paths are summed to form the output signal VS of the circuit which is thus ridded of a large part of the high-frequency parasitic signals.
