Abstract: A method and a device for optical examination of transparent bodies made of plastic, glass, or glass ceramic are provided. The examination is carried out by contactless detection and measurement of the body using optical imaging devices. For this purpose, a plurality of individual images are taken of the body during the examination in different positions relative to the imaging device, which are subsequently analyzed.

Abstract: For removing halo formation, which often occurs on glass-ceramic articles decorated with a ceramic color, a layer of SiO.sub.2 is applied to the glass-ceramic article after the glass-ceramic color has been burnt-in. The layer is preferably 40-200 nm thick. The layer can contain up to 66.5% by weight of oxides, which change the refractive index so that the layer is invisible, the layer being, for example, 85-93% by weight of SiO.sub.2 and 7-15% by weight of TiO.sub.2.

Abstract: Fireproofing gels based on amine salts of acid phosphates are characterised in that they comprise an aluminium component, a phosphorus component, an amine component and if appropriate water in proportions such that, at 5 to 30.degree. C. for more than 24 hours, they form a mixture which is capable of flow, and on heating to temperatures above 45.degree. C. they change into a transparent gel in less than 24 hours. In addition to other uses, such fireproofing gels are particularly suitable for the production of laminated glass constructions having a-fire protection action.

Abstract: Process for the production of decorative glass ceramic articles, the design being sunk entirely or partially into the surface of the glass ceramic, wherein the surface, to be decorated, of the not-yet ceramed base glass is connected as the anode of the region of its glass transition temperature Tg up to Tg+100.degree. C. and a current is allowed to flow evoking an alteration of the surface of the base glass, and wherein the current is permitted to flow until the surface has been altered to a desired depth.

Abstract: A glazing panel which is transparent and fire-resistant, including at least one vitreous structural ply including at least one rough-faced ply composed of vitreous material having a mean coefficient of linear thermal expansion over a temperature range of 20.degree. C. to 300.degree. C. which is not greater than 7.5.times.10.sup.-6 K.sup.-1 and having a rough face for which roughness, R.sub.tm, is not less than 0.1 .mu.m; and at least one layer of intumescent material directly bonded to and in contact with the rough face of the at least one rough-faced ply.

Abstract: The invention offers a simple and economical mounting possibility for gas burners in molded parts made of a brittle-friable material, such as glass, glass-ceramic or ceramic, by means of which gas burners can be mounted without stresses, in a leakage-proof and gastight fashion in cooking surfaces of such a material without having to impose a restriction as to a special appliance and/or a specific burner type. The molded part which is made of the brittle-friable material, is the sole support for the gas burners, however, if the molded part breaks, the gas burners will drop onto a lower metal support so that the gas feed lines do not rupture.

Abstract: A process for producing decorated glass-ceramic articles is described in which an article of crystallizable glass, prior to being decorated with a ceramic color and then converted into a glass-ceramic article by heat treatment with simultaneous burning-in of the ceramic color, is pre-heat treated with a Bronsted acid at temperatures between 50.degree. and 800.degree. C. until the surface layer of the glass article is modified so that the layer of ceramic color sinks into the surface of the article during burning-in/ceramicizing, thereby permitting if desired, a thicker layer of ceramic color to be applied and the production of decorated glass-ceramic articles in which the decoration is flush with the surface of the article to be produced, thereby reducing its susceptibility to damage and wear.

Abstract: A flame-resistant, hardenable polyorganosiloxane compound is described with a content of 2 to 40 weight % hollow glass balls with an outside diameter of up to 200 .mu.m and 3 to 50 weight % of an inorganic intumescent compound which expands at a temperature from 80.degree. to 250.degree. C. The preferred intumescent compound is expandable graphite. The compound can replace the previous compounds provided with polyhalogenated diphenyl compounds in fireproof windows.

Abstract: A fire-retardant glazing is disclosed wherein, especially in case of a fire, a wedge is displaced on a counter bevel in parallel to the pane by means of an intumescent material and thereby generates an extensively permanent contact pressure on the pane in the pane channel.
