Title: Resin section-dividers for a gas-filled communications cable - can harden only after the resin has penetrated fully
Inventor: SCHOENEBECK KARL-HEINZ
IPC: H01B13/30
Filed: 1976-09-04
Abstract: The gas-filled, paper-insulated communications cable is divided into sections by resin plugs, the resin being poured in through temporary openings made in the sheathing. A resin is to be used which hardens only on the application of external heat; the heat is not to be applied until the resin has had time to soak through all the layers of paper and has reached the centre of the cable. This prevents the resin from hardening before it has soaked through all the layers of paper, ensuring that the plug is gas-tight.

Title: Crystallographic analyser for geological investigations - has laser optical system lowered into borehole to test reflection characteristics of rock under investigation
Inventor: STEINMANN CARL RUPRECHT
IPC: G01N21/55
Filed: 1977-01-21
Abstract: The crystallographic analyser for geological investigations comprises a capsule (11) which is lowered into a bore-hole, the capsule containing a tunable infra-red laser (16). The wavelength of the laser emission is selected to match the reflection characteristics of the rock under investigation. The laser beam is split (18) and reflected onto the wall of the bore-hole through a window (13). The reflected ray is split, part being focused onto an optical detector (41). A direct reference beam (21) is reflected back by a series of mirrors (22, 23) through a lens (20) to the detector. Both measuring beam and reference beam are chopped by a motor-driven disc (24) so that both are modulated. The separate electrical signals from the detector lock-in amplifier are fed to a ratio meter so that the absolute value of the amplitude of the laser beam can be eliminated. The intensity of the beam, which varies with the frequency then has no effect on the result.
