Abstract: 1298003 Depositing fibre strands in rectangular containers BREMER WOLL-KAEMMEREI 5 May 1970 [8 May 1969] 21650/70 Heading D1F A process for depositing fibre strands in rectangular undivided containers in which the fibre strand is deposited in helical windings which are progressively deposited in layers in the container by moving the container relative to the strand is characterised in that the strand in each layer is deposited in a zig-zag manner. In a preferred embodiment, the strand deposited in an oblique direction between the longer side walls whereby the pitch of the zig-zag shaped paths is such that at the end of the layer, an incline extends into one corner of the container and the winding is led along the end wall to reach the starting position of a new zig-zag layer, the inclines of which cross the inclines of the lower layer and has the same pitch angle, the process being repeated until the container is filled. In an alternative process, the windings are first deposited adjacent and parallel to a short end wall of the container, and then along a longer side wall by a length equal to the diameter of the winding, the windings are then deposited parallel to the end walls and adjacent the previous layer, the process being repeated until the other end wall is reacted, and the container is filled in this manner. The apparatus comprises an undivided rectangular container 2 mounted on a platform 41 which is movable via wheels 411 on a lower platform 42. The lower platform 42 is movable on wheels 423 in a direction at right angles to the movement of the upper platform 41.

Abstract: 1327204 Semi-conductor devices ASSOCIATED ELECTRICAL INDUSTRIES Ltd 24 Jan 1972 [17 Feb 1971] 4828/71 Heading H1K A thyristor comprises (Fig. 1) a Si semi-conductor body 1 having PNP-layers 2, 3, 4 of alternate conductivity types; N-layer 5 extending from the outer face into P-layer 2. Conducting electrode layers 6, 7 are formed on the respective outer faces of layers 5, 4 and layer 6 also overlaps the exposed surface of layer 2 surrounding layer 5; while conducting layer 8 constitutes a trigger and contacts layer 2. Gold is introduced into layer 3 as a lifetime reducing impurity for minority carriers in restricted regions 9 also extending through layer 4; so as to improve recovery. In manufacture (Figs. 2, 3) the body containing layers 2, 3, 4, 5 and before deposition of layers 6, 7, 8 is strongly heating in nitrogen in a quartz furnace tube; and oxygen is introduced after bubbling through phosphorus oxychloride; to deposit a vitreous surface layer 10 of phosphorus silicate. Further heating in absence of oxygen forms an underlying phosphorus doped silicon layer 11. Slow cooling getters fast diffusing impurities by trapping in layers 10, 11, which are selectively removed by wax masking and etching first in HF and then in HNO 3  + HF. After removal of wax and washing, a layer 12 of Au is deposited (Fig. 3) by immersion in dilute chlorauric acid. Thereafter, heating in N 2  diffuses Au through gaps 13 to form regions 9, and the gettering layer 10, 11 inhibits deposition of Au except in the gaps. Layers 10, 11 and corresponding Au layers are etched off and electrode layers 6, 5 are deposited. Layers 10, 11 may be formed by using O 2  mixed with gaseous phosphines or P 2 O 5  vapour. The process is applicable to other semi-conductor devices.
