Title: Optical beam divider for e.g .fibre optic system - has glass or quartz-glass fibre fused into capillary of similar material with pair ground and polished after curving
Inventor: GUTTMANN JOACHIM
IPC: G02B6/28
Filed: 1980-02-15
Abstract: The beam divider is constructed by first removing the plastic protective layer from a glass or quartz glass light conductor, which is then fused into a glass or quartz glass capillary, which being of an identical material to the fibre, ensures a relatively small difference in the coefficients of expansion of the two components, which are thus almost stress free and ageing resistant. The fibre is longer than the capillary and the finished rod is bent with a defined curve, by heating and laying over a graphite tube with a pre-determined diameter. Subsequently the glass rod is worked on from above by grinding and polishing, until the fibre cross section, in the centre of the ground surface, is semi-circular. Two finished fibres can be brought together so that the fibre cores lie in close proximity, allowing light from one fibre to be coupled into the other one.

Title: Process for the production of shuttles and shuttles produced by this process
IPC: D05C11/18
Filed: 1981-03-10
Abstract: The production of shuttles for embroidering or quilting machines requires a large number of operations. Hitherto, each individual shuttle was produced from a piece of sheet metal, a blank being produced in a number of deep-drawing operations. In this process, it was transferred from one workstation to the next by hand. The upsetting at the tip required a separate operation. If this last operation is omitted, the blank of the shuttle can be produced in a largely automatic progressive deep-drawing process. A multiple die is supplied with a sheet-metal strip in which, first of all, notches (1, 11) are cut to allow the material to flow or be drawn in more easily during the various deep-drawing stages (TZ1-TZ4). Finally, the shuttle blank is punched out of the strip in a final stage (ST2) and then finished. <IMAGE>
