Inventor: BOSSELMANN THOMAS DR
IPC: G01R15/24
Filed: 1995-02-22
Abstract: Two light signals (L1', L2') run in opposite directions through a series circuit a first optical fibre (4), a first polariser (5), a Faraday sensor (3), a second polariser (6) and a second optical fibre (7). In order to adjust the working point, the polarisation planes of both light signals are further rotated by rotation means (8) between both polarisers in opposite directions over a predetermined angle of rotation. A measurement signal (M) that is independent from vibrations and flexural influences in the optical fibres is derived from the luminous intensity (I1, I2) of both light signals (L1, L2) after they run through the series circuit.

Patent DE-19511592-A1 (DE)
Inventor: BUECHNER OLIVER DIPL ING
IPC: C03C25/143
Filed: 1995-03-29
Abstract: A method of coating an optical cable/wire or light-wave conductor with powder in a tubular chamber is disclosed. By sucking off air at outlet 11 as the cable moves through the chamber, an underpressure is created sucking in powder 5. At the same time, the underpressure also creates an air current which flows along the cable causing powder to be deposited along and around its length. Alternatively, the flow of air may be in the opposite direction to the movement of the cable through the chamber. In both cases, the thickness of the coating layer is controlled by regulating devices and the powder may be electrically charged to enhance coating. The air inlet can take the form of an annular nozzle arranged around the cable.
