Title: Decorating glass ceramic surfaces - using current to heat surface to above glass transition temp. and change the surface structure to allow the subsequent decoration to sink into the surface
Inventor: NAS PETER DR
IPC: B44F1/06
Filed: 1992-08-14
Abstract: Method of producing decorative glass ceramic articles consists of connecting the glass material as an anode and allowing a current to flow through the surface at a temp. of between the glass transformation (Tg) and Tg+100 deg.C.

The current is delivered by electrodes (1) and conductive coating (4), pref. of graphite foil. The current is produced by a corona discharge between the wire tip (5) and the surface of the ceramic (3). The corona discharge has an applied voltage of 1-10 KV. USE/ADVANTAGE - Making high temp. resistance ceramic articles such as crockery, oven and chimney view windows, fine protection glass, hot plates and fireplace tiles. Enables the decoration to sink into the surface of the glass ceramic thereby avoiding future attack from cleaning fluids, etc. which tend to wear away the prior art decorations which are in relief above the ceramic surface.

Abstract: The object of the invention is to subject thermoplastic film webs (5) to a defined shrinkage, within the biaxial stretching process, with the application of small adjustment forces for changing the division and position of the clip chain and tenter clip (2) and to provide a device for carrying out the process. According to the process, this is carried out essentially in that   1. in the inlet region and/or heating region of the stretching machine, the division of the clip chain is varied in a manner known per se so as to reduce the spacing between the individual clip bodies and simultaneously a positional variation of the tenter means (18,19) receiving the film web edge is carried out to take up the material excess resulting from the spacing reduction,   2. the films are transversely stretched, 3. the positional variation of the tenter means in the fixing region is cancelled and, 4. after the film web edges are released, the shrinkage division is cancelled.   A device for this purpose consists of a clip chain whose tenter clips (2) are equipped with means, known per se, for divisional variation and the tenter clips are designed as pivot clips or at least the tenter means (18,19) within the clip are positionally variable. <IMAGE>
