Title: Joining optical (e.g. glass) fibres - by inserting the two ends in a glass tube which is heated and crimped
Inventor: POHL KURT
IPC: G02B6/38
Filed: 1973-12-21
Abstract: Optical waveguides, e.g. glass fibres, are joined to each other or to appts. such as a transmitter or receiver, using a small tube metal, glass or plastic, with a bore dia. smaller than twice the dia. of the glass fibre. The two optical fibres are fed into the tube, one from each end, until the two meet at the middle of the tube, and pressure is then exerted on the outside of the tube at three places around th dia., i.e. at intervals of 120 degrees, thus forming three flats on the outside surface of the tube and pressing it onto the two fibres; if required, heat can be applied to the glass tube during this operation. A non-detachable connection is thus obtd. with the lowest possible attenuation of transmission.

Patent DE-2447331-A1 (DE)
Title: Plate pressure filter with rotatable pack - having intermeshing teeth on hub between plates with gaps to allow filtrate passage
Inventor: WINNICHNER HERMANN
IPC: B01D29/41
Filed: 1974-10-03
Abstract: Pressure filter arrangement, esp. a pressure plate filter, has pressure housing with a plate package mounted inside it. Adjoining plates are mounted together to form a central hub, intermeshing with teeth, with gaps at the crown of each tooth to form a passage for filtrate. The ratio of tooth crown wt. to tooth foot wt. in the intermeshing teeth compared to the tooth crown surface form these passages. The intermeshing teeth can be in spiral form. The arrangement is of use with pressure disc filters where the filter plates are cleaned by rotating the bundle of them. On conventional arrangements, the passages for the filtrate form a significant part of the cross section, and thus weaken its ability to take a rotational moment. Also the flow direction is changed, thus increasing pressure drop and reducing the effective loading.
