Coatings, which act as barrier layers to inhibit migration of alkali metal ions from a glass surface and/or act as colour suppressing underlayers for overlying infra-red reflecting or electrically conducting layers, are deposited by pyrolysis of a gaseous mixture of a silane, an unsaturated hydrocarbon and carbon dioxide on a hot glass surface at a temperature of 600 DEG C to 750 DEG C.

The invention relates to a control and arrangement for continuous laser-welding of sheet or strip. Control means and an arrangement are described, by means of which sheets coated on one or both sides and having the same or different thicknesses and different or identical geometries (reflection) can be welded up at high weld quality, such as is applicable, for example, in car body construction. The...

Process for the preparation of vinyl chloride homo- and copolymers in powder form capable of yielding plastisols. A spray-drying operation is carried out on a vinyl chloride homo- or copolymer latex. The operation is carried out so that the processing temperature of the said latex to be subjected to the spray-drying operation is at least 40 DEG C and lower than the temperature of onset of deg...

Reinforced gypsum boards are produced from gypsum (semi-hydrate), if appropriate reinforcing materials, preferably cellulose particles, polyisocyanates being admixed during the manufacture of gypsum boards and/or being applied to the surface of the gypsum boards. The invention also relates to polyurea-modified reinforced gypsum boards of gypsum (semi-hydrate), if appropriate reinforcing mater...

CASE: FR-6387-A FLAME-RETARDED ABS FORMULATIONS WITH HIGH IMPACT STRENGTH The impact strength of articles made from a flame-retarded formulated ABS resin containing an impact modifier is increased by forming a concentrate or masterbatch containing the flame retardant and impact modifier, blending the concentrate with ABS resin and extruding the resultant blend.

The invention relates to a simplified and reliably functioning drill tool for a sinker drill for drilling in loose earth, such as when reinforcing the foundations in connection with building. The drill tool according to the present invention is in two parts and consists of an upper cylindrical transition piece (1), its central axis coinciding with the rotary axis of the drill tool, and provided wi...

The invention relates to a process and an apparatus for blow moulding a hollow article from thermoplastic material, with a flange ring projecting outwards from the peripheral wall of the hollow article, the blow mould having an annular recess for producing the flange ring of the hollow article, which recess is designed such that it can be varied with respect to a fixed blow mould part by means of ...

In an apparatus for removing portions of identical materials (4) in the form of pieces by means of a sliding part which is encased in a dispensing container and operated from the outside and whose dispensing sector (5) is filled from inside the container and can be emptied outward, the sliding part is in the form of a tube section (1) which has one or more dispensing sectors (5) and is fed through...

The invention relates to a formed piece which includes a continuous matrix which comprises A) inorganic solid silicondioxide powder particles whose size is approx. 50 A - 0.5 μm, and B) solid particles whose size is 0.5 - 100 μm and which are at least an order of size larger than the corresponding particles mentioned under A), with the proviso that at least 20% by weight of the B particles are Por...

The present invention is directed to an artificial joint for reproducing human joints in particular, consisting of at least two joint parts with spherical functional surfaces that move relative to each other, where the curvatures of the functional surfaces having a circular cross-sectional contour are convex/concave relative to each other, so their centers of rotation are located inside the joint ...
