Title: Web Formation
IPC: D04H3/04
Filed: 1979-09-20
Abstract: Forming a coherent web of fibrous strands by feeding an array of strands, e.g. woollen yarns, 10 side by side into the nip of a pair of rollers 16, 18 one of which 16 has a series of parallel V shaped grooves 20 and applying adhesive to the array, e.g. from a trough 22 and supporting the web 24 so-formed until the adhesive cures or is cured. Compression of the strands in the V shaped grooves 20 prevents or reduces strike-through of the adhesive to the upper face of the web. A second pair of nip rollers 26, 28 may be provided with the roller 26 having grooves aligned with roller 16 to provide a first curing zone 25. If desired a backing sheet 32 from a roll 34 may be fed into the second nip where it will laminate to the web 24. A second curing zone 31 completes the curing and the finished web is wound on to a take-up roller. The web produced is a decorative fabric which may be used for a variety of products, such as lampshades and wall coverings. <IMAGE>

Title: Field effect semiconductor devices
IPC: H01L21/8236
Filed: 1979-11-07
Abstract: In the fabrication of a field- effect semiconductor device, prior to formation of a doped region 103 to which electric contact via a metal contact 107 is to be made in the completed device, a portion of the substrate is doped with impurity material so that when said region 103 is subsequently formed a portion of said region 103 is deeper than the remainder of said region 103, and said metal contact 107 is formed so as to contact said region 103 only over an area overlying said deeper portion. By this means the junction is locally deepened beneath the contact and the possibility of junction spiking is reduced. <IMAGE>

Title: Recovery of iron and titanium metal values
IPC: C22B34/12
Filed: 1979-11-21
Abstract: The metal values are recovered from iron- and titanium-bearing sources such as an ilmenite ore by crushing the source, subjecting it to a reductive roast, then leaching it by treatment with an aqueous solution of a halogen-containing compound to form dissolved titanium halides and iron halides. Thereafter the soluble titanium halide is precipitated as titanium dioxide by treatment with iron oxide and the titanium dioxide is separated and recovered. The soluble iron halide is then crystallized and one portion of the crystals is subjected to a reduction step to form metallic iron. A second portion of the iron halide crystals is oxidized to form iron oxide which is recycled to precipitate the titanium dioxide. <IMAGE>
