Title: Improvements in or relating to a device for obtaining a purer ingot in ingot casting
IPC: B22D7/12
Filed: 1960-12-06
Abstract: 906,845. Casting processes. DAUSSAN, H. J. Dec. 6, 1960 [Dec. 7, 1959], No. 41902/60. Class 83 (1). A device for concentrating impurities introduced by the pouring jet in the head of a ferrous metal ingot comprises two concentric layers A, B which form a system of vertical channels, the layers having different degrees of resistance to destruction by the molten metal. The device may be formed of corrugated cardboard fireproofed with sodium silicate, the layer A being of less resistance by reason of its larger channels. A rebate 6 is thereby formed which is stated to trap the impurities, the effect being assisted by the passage of gases f through the vertical channels. The rebate may be in part preformed, and the layer B may be inside the layer A.

Abstract: 997,242. Knitting. SCHUBERT & SALZER MASCHINENFABRIK A.G. Nov. 27, 1961 [March 10, 1961], No. 42278/61. Headings D1C and D1K. [Also in Division F2] A two or more feeder circular knitting machine has means for varying the stitch length smoothly in both the wale and weft directions over part of the circumference of a knitted article e.g.: to form a heel bulge. As shown, stitch cams I, II, III and IV biased upwardly by springs F have bolts 83 which engage levers 82 connected to levers 8 carrying rollers R which engage cam 1. The angles between the radii connecting the stitch cams to the cylinder axis are equal to the angles between the lines joining the corresponding rollers R to the axis of rotation of cam 1 which is keyed on shaft 11 rotated synchronously with the needle cylinder. Cam 1 is slid on shaft 11 between positions A and B by a fork 13 having a groove 13 engaged by a crank pin 15 on a wheel 14. Rotation of wheel 14 to adjust cam 1 and hence to vary the stitch length progressively is controlled by the pattern chain through a ratchet and pawl and gearing. Cam 1 is shaped so that its action through rollers R on the stitch cams produces the variation in stitchlength in the wale and weft directions. The cam 1 may have, Fig. 5, a portion 2 which is adjusted by screw 21 and locked by screws 23 mounted in slots. The cam followers may be moved instead of the cam.

Abstract: 1355107 Active filters WESTERN ELECTRIC CO Inc 17 Sept 1971 [21 Dec 1970] 43504/71 Heading H3U A digital filter for performing p successive digital filtering operations, each of order m, on digitally coded signal samples from each of a sources, comprises a store 112 feeding m cascaded shift registers, e.g. 132, 142 and an arithmetic unit 192 which sequentially receives signals from the store and registers, and which provides an output which is fed back to the store input. Input signal samples are stored in store 112, the output I from which feeds the two registers 132, 142 to produce delayed signal samples X, Y, and a further store 122 produces an output J. The four signals I, X, Y, J are then sequentially fed by gates 114, 134, 144, 124 to arithmetic unit 192 where they are multiplied by predetermined constants and added. Signal X is first multiplied by a constant E, and the product is stored in accumulator 156. Next, the value I is added to the stored product, and the resulting store sum EX + I is transferred to store 112. The signal Y is then similarly multiplied by a constant D, the signal I is added to it, and the resulting signal DY + I transferred from the accumulator to stores 112, 122. Signals CX + J and BY + J, where B, C are further constants, are similarly produced and are stored in 122. Registers 132 and 142 are now shifted, signal J multiplied by a further constant A and the product AJ transferred from accumulator 156 to register 112. The described arrangement is used with series data, but may be modified for parallel data, Fig. 7 (not shown). The various gating signals are derived from a memory unit, Fig. 2 (not shown) and the circuit is equivalent to a second order direct filter, Fig. 1 (not shown).
