Abstract: An optical fiber connector comprising a manipulator 11 in the form a cylindrical tube having a throughbore 12 which receives a carrier 13 in the form a cylindrical tube having a throughbore 14. The carrier 13 receives an optical fiber assembly 15 which is to be coupled to another optical component by means of the connector. The manipulator 11 has two pairs of adjustment screws 18a, 18b and 19a, 19b, which can be used to displace the carrier and optical fiber assembly within the manipulator. The manipulator also includes two adjustable spring plungers 22 for applying a variable resilient biassing force to urge the carrier against the contact points of the adjustment means when it is inserted into the manipulator. The carrier 13 includes plural pads 24, which have flat, planar surfaces 25 and protruding studs 26 mounted therein. The pads are arranged in holes 27 in the carrier body such that their flat surfaces form part of the outer surface of the carrier.

Abstract: Colloidal compositions based on fillers, sol oxides, poly silicates, and, optionally, pigmenting agents, and their method of production the solid disperse phase not only operates to cross-link but also as an overmatrix incorporating macroparticles therein. The dispersant is finally chemically set with excess setting agent so that the preliminary product can be finalized to the desired material. For this purpose a matrix-like substance of filler-like macroparticles and sol oxide (crosslinling substance) and a buffer are brought together for assisting the formation of the overmatrix and are processed. This substance is pigmentable by introducing a variation mixture into the substance, so that a wide range of characteristics can be obtained. The substance directed at the desired material, namely a hydration and balancing process stage and a subsequent setting and stabilizing process stage.
