A mesh () is placed around a bundle () of fused glass fibers. The bundle is then immersed in a leaching bath (). The ends of the bundle are protected from the bath fluid by furrules (). Some of the glass of the bundle is leached out, so as to provide a flexible fiber bundle.

A method of mounting electro-optical devices on an optical element using an auxiliary substrate is provided herein. Electro-optical fiber optic assemblies are also described herein.

Method of mounting optoelectronic devices on an optical element and article

A method of protecting a glass substrate, especially a display glass or a hard disk blank made from a glass or a glass-ceramic, from unacceptable surface damage and scratches, often leading to glass breakage, during processing and transport, is described. This protective method includes applying a removable protective coating made of at least one polymer layer, or at least one polyvinyl alcohol layer, to the glass substrates by spraying or rolling the polyvinyl alcohol or a polymer solution of the polymer to be applied in a polar organic solvent, onto the glass substrate, or dipping the substrate into it. Then when the substrate is ready for its end use, the protective coating is removed by washing in water or polar organic solution so that a residue does not remain on it. The glass substrates, protected in this manner have outstanding surface quality and improved hard disk blanks can be economically produced from them.

Method of protecting glass substrate surfaces

A method of protecting a surface of a display glass or a hard disk substrate during processing arid transport includes applying at least one polyvinyl alcohol or other polymer protective layer on the surface, which is soluble in polarorganic solvents, so that the layer can be removed after processing and transport by washing in heated water or a polar organic solvent without leaving residues on the surface. The polyvinyl alcohol used to make the protective coating has an average molecular weight of &gE; about 60,000 g/mol and a hydrolysis degree of &gE;95% and the at least one polyvinyl alcohol layer is dried by heating at temperatures of about 150&deg; C. or less to form the protective coating after applying the polyvinyl alcohol layer. The other polymers are less soluble in water than polyvinyl alcohol but are easily removed with organic solvent.
