Title: Manufacture of channelled ceramic elements
IPC: G02B6/28
Filed: 1981-07-17
Abstract: A channelled ceramic element 1, in particular for forming an optical fibre termination or connector, is produced by embedding one or more lengths of silica fibre, preferably coated with resin, in a body of powdered ceramic material which is non-silica-based, in a suitably shaped die, pressing the powder, and sintering the pressed compact: during sintering, the resin coating of the fibre or fibres (if present) is burnt off, and the silica of each fibre reacts with or is absorbed by the surrounding ceramic material, to leave a smooth-walled channel into which an optical fibre to be terminated, or pairs of optical fibres 6,7 to be spliced can be inserted. Suitable ceramic materials are alkaline earth metal titanates and zirconates. Methods for manufacturing a rectangular connector block for a plurality of pairs of fibres, a ferrule for terminating a single fibre, and connectors for coupling single fibres end-to-end and laterally, are described. <IMAGE>

Title: Printing process and printing press
Inventor: HAMILTON CLIFFORD HORNE
IPC: B41F17/00
Filed: 1981-10-14
Abstract: Distinct sequences of different groups of characters are repetitively printed and juxtaposed, the repetition periods also being different so that large numbers of separate combinations can be produced, e.g. for bingo cards. For example paper web (2) passes successively through four printing stations (3, 4, 6, 7), each having a respective printing cylinder (8, 11, 14, 17). Each printing cylinder carriers different groups of characters arranged in rows, and the different printing cylinders have different circumferences and different numbers of rows. As the web passes through the printing stations, matter is successively over printed at the printing stations to produce sets of characters. Because the different printing cylinders carry different numbers of rows of characters, different permutations of characters from the printing cylinders are produced, to give a succession of sets of characters having different combinations of characters therein. <IMAGE>
