Patent DE-19747096-A1 (DE)
Title: Flat lamp with compact optical fiber disc arrangement
Inventor: WILLING ACHIM DR ING
IPC: G09F9/33
Filed: 1997-10-24
Abstract: A flat lamp has a compact optical fiber disc arrangement with side light entry edges into which the light of a number of LEDs is fed. There are measures interrupting total reflection for deflecting the light towards one or both sides of the disc arrangement in a flat region provided for this for the illumination or rear lighting of pictograms, especially safety signs. At least between the light entry edges for supplying the LEDs and the surface provided for the light radiation, an edge zone is provided in which the light is guided but not radiated into the outer space. The edge zone is dimensioned so large that the fed-in light can mix sufficiently in its region in order to effect a sufficiently uniform light radiation on the light-radiating surface.

Patent DE-19755940-A1 (DE)
Inventor: ALIPAS MARKUS
IPC: B29C44/06
Filed: 1997-12-16
Abstract: Initially, a first mixture of raw materials and rubber is expanded and calendered in order to produce a thermally insulating plate-shaped article made of expanded elastomer cellular rubber. At the same time, a second mixture of raw materials is extruded and calendered. The material strips thus obtained have different ranges of properties and their surfaces are pressed together. The two material strips whose surfaces are joined together by means of interpenetrating chains of molecules in the micro range are first supplied with heat for initial vulcanisation in order to produce a resistant composite strip for containment of the gases that are formed in a subsequent expansion. The composite strip is then supplied with further heat so that vulcanisation can continue in order to produce a strong surface bond by means of chemical cross-linking and to produce expansion by means of foaming agents in order to obtain a combined product made of expanded elastomer cellular rubber for further processing into said plate-shaped article.
