Abstract: 1,231,838. Aerating liquids. A. SCHREIBER. 19 Nov., 1968 [20 Nov., 1967], No. 54934/68. Heading B1C. [Also in Division Cl] Sewage is aerated in an aeration space into which air is introduced by a plurality of rotating diffusers near the bottom of the space, rotation of the body of sewage therein being braked by the introduction of sewage taking place near the bottom of the aerating space and discharge near the top, or vice versa, so that the air bubbles rise obliquely. In Figure 1 the diffusers 6 rotate in an aerating space 3 defined by a wall 4 spaced both from the bottom 1 and the liquid surface; the wall 4 may be telescopic being supported by floats 16 and having guide vanes 13. In another embodiment, Figures 3 and 4, the aerating device may cause circulation between two elongated tanks 7 through ports 9, 10, the boundary wall 2 of the tanks and that 4 of the aerating space being coincident for about half the periphery of the latter. The central dividing wall 12 may be continued to the diffuser support 8 by partition 11, 11' having a slot 15 for passage of the air supply pipe. These may be fixed diffusers (14) in the tanks 7 (see Figure 7, not shown); the speed of circulation prevents sludge settling in the tanks 7. The diffusers may be oval in cross-section to reduce resistance, or to convey the sewage upwardly or downwardly when angled to the horizontal, and there may be diffusers at more than one level.

Abstract: 1,257,216. Gripper axminster looms. FIELD CREST MILLS Inc. 14 Feb., 1969 [15 Feb., 1968], No. 8260/69. Heading D1E. A gripper Axminster loom has grippers with a very small stroke which remain between the dents of the reed at all times. Operation of grippers: In Figure 3 a tuck wire 38 has moved to hold clear previously inserted tufts and the grippers 35a, 35b have pulled out lengths of tuft material P. The fell of the fabric is then moved to position B and a needle 26 inserts a loop of weft yarn. The shed then changes, a cutter 37 severs the tufts and a reed 24 beats up the weft with the tufts still held by the grippers (Fig. 4, not shown). As the reed retracts the grippers move towards the selectors 36 taking with them the legs of the tufts and the position of release of the tufts determines whether or not the legs of the tufts have equal length. Whilst the grippers are again closing over the selected tufts the tuck wire 38 again moves (Fig. 2, not shown) to hold clear the released tufts. The cycle reccommences.  Beat-up motion: The reed dents 24 (Fig. 13) are attached to a sley 66 that is part of a pivoted crank 65 driven by links 63, 62, 60 and a follower and cam 57, 56 on the main shaft 50 of the loom. Pile yarn selectors: The pile yarn selectors 36 (Fig. 13) are mounted on a frame 73 that is adjustable both horizontally and vertically to bring the selectors the correct distance from the breast beam 70 (Fig. 3) and in the correct alignment with the gripps 35a, 35b. The selectors 36 have yarn passages 92 with springs 93 and are operated by cords 95a (Fig. 13) from a jacquard 95 driven by a chain 96 (Fig. 11, not shown) from the main shaft 50 of the loom.  Warp let-off, shedding: The warp 6 comes from beams 100, 101 at the front of the loom and passes backwardly over whip rolls 110, 111 (Fig. 13) and a fell shifting roll 120 to the heald frames 27 operated by links 130, 131 from a lever 13 pivoted by a cam 142 (Fig. 18) on a shaft 51.  Take-up; Fell shifting: Normal take up (Figs. 14, 16) is by way of a spiked roll 150 at the top of the loom driven by a crank 180 on the reed shaft 64 and a ratchet gear mechanism 167, 171, 172 which engages a stub shaft 197 on a further ratchet wheel 166 to advance the roll 150. To advance the fell to the position B (Fig. 3) to allow for gripper movement the further ratchet wheel 166 is advanced by a crank operated lever 193 that also operates the fell shifting roll 120. The cloth advances over the front of the loom to a friction driven cloth beam 160 (Fig. 9). Pile cutting: The pile cutter 37 (Fig. 22) is moved upwardly so that serrations 300 engage the tufts. A plurality of knives 301 then reciprocate to sever the tufts. Framework: A walkway 107 (Fig. 9) is provided between the sidewalls of the loom and supports 105 are provided for the warp beams and stanchions 157 for the cloth beam. (For Figures see next page)

Abstract: 1,265,375. Printed circuits; semi-conductor integrated circuits. WESTINGHOUSE ELECTRIC CORP. 1 May, 1969 [31 May, 1968], No. 22228/69. Headings H1K and H1R. In a micro-electronic component, e.g. an integrated circuit, overlapping portions of conductive patterns on a substrate are spaced solely by an air gap, certain of which portions form tabs, at least one of which is bent to join adjacent patterns. In a preferred method of forming conductive patterns on a substrate, a semi-conductor integrated circuit substrate 80, Figs. 8 and 9, of silicon having an insulating layer 81 of silicon dioxide has deposited thereon by spluttering (or vacuum evaporation) a first metal layer of chromium covered by gold. A first photo-resist mask is then applied and a first conductive pattern 84 of gold is plated (or electroplated) on layer 82, the mask then being removed. These steps are repeated for a spacer layer 86 of nickel and a second conductive pattern 88 of gold. Finally, the spacer layer 86 is etched away to form the air gap between the conductor cross-overs, and any exposed portions of the layer 82 are etched away. Selected ones of the cross-overs may be broken, thus forming a pair of tabs either or both of which may be bonded to the lower conductive pattern by cold bonding, electron beam; or electrostatic attraction. In alternatives, the insulating layer 81 may be formed of successive layers of silicon dioxide and silicon nitride, the chromium in layer 82 may be replaced by titanium, zirconium, or aluminium, and the spacer layer 86 may be of tin, copper, silver, cadmium, lead, alloys of these metals or metal oxides deposited by spluttering or evaporation. Further, the layer 88 may be of aluminium, silver, copper or palladium, or may be a foil with portions removed to form the desired pattern. The layer 88 may further be a resistive layer of nickel-iron alloys. For highly accurate configurations, a thin flash of gold is deposited on the spacer layer 86 and a thin layer of nickel is overplated on the layer 88. In Figs. 1 and 2, the substrate is a semi-conductor integrated circuit protected by an insulating layer 14, a conductor 26 is provided between contacts 21, 22 and two tabs 33, 34 extend from contacts 23, 24 over conductor 26, tab 33 making contact with conductor 26. A microwave transmission line may also be formed, Fig. 5 (not shown).
