Title: Optical waveguide where core is covered by a winding - of separate fibres with a lower refractive index than the core
Inventor: OESTREICH ULRICH DIPL ING
IPC: A61B18/22
Filed: 1975-05-13
Abstract: Multilayer optical transmission element surrounded by a protective sleeve and consisting of >=1 core and >=1 jacket, where the material used to make the jacket has a smaller refractive index than that of the core. The novelty is that the core is covered or wound with fibres made of the jacket material. The core may consist of a thin-walled hollow cylinder which is filled with a material possessing a lower refractive index than that of the thin wall, and the core may itself consist of a bundle of fibres but using a different lay to that employed in twisting the jacket fibres round the core. The core and jacket fibres may be drawn simultaneously and the jacket fibres wound round the core, e.g. using a rotating die for the jacket fibres. Used for example in optical waveguides with low attenuation. The cores can be joined together without the influence of the fibres in the jacket and, if a jacket fibre breaks it has no effect on the core; the overall mechanical reliability of the optical cables is also increased.

Title: Pneumatic conveyor for tunnel packing - uses bunker gate seals which operate when no material is flowing
Inventor: HOELTER HEINZ
IPC: B65G53/66
Filed: 1975-12-27
Abstract: The pneumatic conveying system is used where continuous flow is required, e.g. in tunnels where packing or stopping material has to be supplied fast and continuously over lengthy periods to ensure successful packing or sealing. The seals (5) at the top and bottom of the filling bunker are switched in a sequence, which ensures that they always operate when no material is in flow and thus are not exposed to wear. The switching sequence starts with the top gate open, and the filling screw feeds material into the bunker until the level gauge signals full. The screw is halted, the gate closed and the control valve opened. This operates the bottom gate seal (5) and the screw feeder (6) to fill the surge or buffer bunker (7), and thence via screw (8) into the blow-line (9). Compressed air is supplied (10) when the feeder screw (8) starts, and the bunker is emptied down to the lower gauge (4).
