Abstract: Method of manufacturing optical couplers from polymers, the coupler structure being produced with the aid of an injection-moulding process and amorphous polymers, in particular PMMA, polystyrenes, polycarbonates, polyolefins, polyesters, polysulphones, polyethersulphones, polyetherimides, polyacrylates, polyamides or polyestercarbonates being used with preference as polymers. The coupler element is solid and may be coated with a polymer which has a lower refractive index than the coupler, so that the diversion takes place in the coupler itself.

Abstract: HOE 90/F 095 Process for the production of optical couplers from polymers A process for the production of optical couplers from polymers in which the coupler structure is produced by injection molding and the polymers employed are preferably amorphous polymers, in particular PMMA, polystyrenes, polycarbonates, polyolefins, polyesters, polysulfones, polyether sulfones, polyether imides, polyarylates, polyamides or polyester carbonates. The coupler element is solid and may be coated with a polymer which has a lower refractive index than the coupler, so that the light propagation takes place in the coupler itself.

Abstract: A novel light detecting device consists of a plate-like light- absorbing body and at least one optical waveguide connected thereto. Both parts of the light detecting device contain a fluorescent dye, whereby the irradiated light is converted into a fluorescent radiation. This radiation is passed by total reflection to a light- sensitive semiconductor element and measured there. The light detecting device is suitable as a light barrier, optical fibre rotary speed measuring device or UV detector. … …

Abstract: The fibre optics luminous sign according to the invention essentially comprises a luminous body, a light source and a system of optical waveguides which connects the luminous body and the light source. The luminous body is a plate-shaped structure made of thermoplastic and provided with a multiplicity of holes in which the optical waveguides end directly. The luminous sign is simple to manufacture and is characterised by a shallow installation depth. It can be used in particular as a rear light for a motor vehicle.

Abstract: A thermoplastic molding compound consisting of units of 2,3-difluoroacrylic acid esters or their deuterated derivatives, or containing units of these esters, is distinguished by a high glass transition temperature and a high transparency. It is therefore suitable for the manufacture of beam waveguides for long transmission distances and high continuous use temperatures.

Abstract: Described are electret fibres with improved charge stability (stabilisation) which consist of a material which predominantly contains a fibre-forming addition or condensation polymer and 0.01 to 30% by weight (preferably 0.01 to 10, in particular 0.1 to 5, % by weight), based on the weight of the material, of organic or organometallic charge control agents, as is contained in toners for electrophotographic processes, and a process for the production thereof. Also described are textile materials containing these electret fibres.

Abstract: High-performance optical couplers for polymer light guides are obtained if light guides are grouped together by means of a piece of plastic shrink-fit tubing and fused. The shrink-fit tubing is thereby heated above the shrinking temperature. The method is simple and inexpensive.
