Title: Forming single crystal silicon ribbons - by pulling at small angle over edge of meniscus attachment member
IPC: C30B15/06
Filed: 1981-09-14
Abstract: Crystalline ribbon (14) is formed by heating a melt in a rimmed crucible (10), placing a seed crystal (34) on the melt surface and pulling the seed from the melt at a low positive acute angle relative the melt surface at a speed commensurate with the longitudinal growth of the ribbon. Separate site of attachment (20) is provided inwardly of the crucible rim for a meniscus formed by the melt from the lower face of the ribbon as it leaves the surface of the melt to reduce spillage and freezing. The growth rate of the ribbon is passively adjusted to changes in the speed of movement of the ribbon by drawing the growing end of the ribbon from the surface of the melt above sub surface stabiliser (22) having an uppermost forward portion arranged closer to the melt surface than the lowermost rearward portion thereof, the crystal growing portion of the melt is thermally isolated from the remaining portion. Produces a high quality semiconductor ribbon of uniform dimensions without any cutting and waste of material, at a high rate of production.

Title: Bituminous covering layer for insulating roofing sheets - obtd. by coating fibrous web contg. absorbent material with hot bitumen and rolling
IPC: D06N5/00
Filed: 1982-09-16
Abstract: Finishing material for heat insulating panels comprises a synthetic fibre felt in which the interstices in the felt are virtually completely filled with a bitumen-absorbing substance (I) and the felt is then coated with a hot bitumen mixt. rolled in the hot state and gradually cooled so that the bitumen is absorbed by the (I). Pref. (I) are cellulose fibres or asbestos fibres, the synthetic fibre felt contains ca. 20 wt.% (I) and weighs 35-100 g/m2. The bitumen mixt. is pref. applied in an amt. of 50-150 g/m2, the coated felt is rolled on a heated cylindrical roll and the rolled material is cooled in the covered state for 10-24 hrs. Pref. the finished material weighs ca. 200 g/m2. The bitumen is gradually absorbed by the (I) whilst the material is stored in the hot rolled state, so that after cooling the individual layers in the roll do not stick to each other. This avoids the necessity e.g. of strewing sand on the surface of the bitumen to prevent sticking as with previous bitumen coated materials, and saves considerable wt. The materials can be made in the form of long rolls contg. 500-1500 m of material as opposed to only 100-300 m in rolls of prior art material.
