Title: Forked optical light guide branch mfr. - by glow discharge butt welding of reduced branch cross=section
Inventor: KOESTLER GUENTER ING GRAD
IPC: G02B6/28
Filed: 1977-04-20
Abstract: Forked branches of optical light guides are produced by welding by reducing the end faces of the branch fibres through a ground inclined flat. The remaining end faces are butt-joined to the end face of the trunk fibre where they are fixed to each other in a T-joint. The ends of the branch lines of the optical light guides are reduced in dia. by etching, followed by grinding a flat at an angle of 5 degrees so that they fit stepless to the end face of the incoming optical light guide. The reduction of the end face areas of the branches causes a stepless fusion of the fibres, particularly if a welding method based on a glow discharge gap is used.

Inventor: LEHR GUENTER DR
IPC: C08G63/78
Filed: 1977-08-03
Abstract: A continuous process is described for the prepn. of polybutylene terephthalates (PBT) of intrinsic viscosity n 0.2-1.4 dl/g (0.5 wt.% soln. in 50:50 phenol-tetrachloroethane at 25 degrees C). A molten mixt. of mono- and/or bishydroxybutyl esters of terephthalic acid or of PBT oligomers of low viscosity at 160-300 degrees C is transported, together with a heated inert gas, as a two-phase annular current across a helical reaction tube, externally heated, of dia. 3-100 mm (esp. 40-50 mm) and dia./length ratio of 1:400 to 1:2000. During the process, a pressure difference is maintained between the entry and exit of the reaction tube, the absolute pressure at the entry being 1-100 bars (pref. 1-30 bars). The viscosity of the annular current (determined at the temp. of reaction) is 1-104 poise. A circular current is set up between the surface of the molten mass and the wall of the tube due to the effect of the curvature of the tube and a gas flow of 20-300 m/s. Reaction process in the liq. phase and/or at the interface of the molten mass and the gas. Dwell time in reactor is reduced, which reduces the formation of tetrahydrofuran and of degradn. prodn. of PBT of high COOH content (inhibiting the polycondensation reaction) and other by-prods. of reduced heat stability.
