Title: Multi-system circular knitting machine
IPC: D04B1/24
Filed: 1971-10-19
Abstract: 1350778 Knitting-machines E MAYER [trading as MAYER & C1E] 19 Oct 1971 [20 Nov 1970] 48492/71 Heading D1C A cylinder and dial machine for knitting several flat fashioned blanks has, associated with each knitting region and rotatable with the needle beds, two displaceable carriages carrying instruments for activating needles. The carriages e.g. 11, 12 in the cylinder and 13 14 in dial are associated with the margin of each blank, and move along fixed tracks, e.g. 23, 33. The carriages are initially set at a minimum spacing a corresponding to the narrowest width of the blank. As knitting proceeds they are moved further apart to a spacing b. Each carriage is provided with a star-wheel 63 which is indexed by a projecting cam 61 or 97 and drives a spiral track 103. The spiral is in engagement with pins 92 on the corresponding fixed track, 33. Rotation of the spirals thus moves associated carriages further apart along the tracks. Each carriage carries two spaced lifters 48-dial, 74-cylinder influenced by a closed cam track 78 see Fig. 7 for the cylinder (the dial needles and jacks are similarly controlled-Fig. 3 not shown). The jacks 66 of the fashioning needles carry a high butt 69 which normally moves in the inactive track 75. When a lifter 74 is moved in a position below a fashioning jack, the rise of track 78 lifts lifter 74 so that butt 69 moves through the passage 76 into the active track. The shape of track 78 ensures that the corresponding needles knit at once, whatever the pattern mechanism has dictated. At subsequent systems the fashioning jacks are influenced by pattern slides 65 in common with the knitting jacks. The carriages moved to activate further jacks at alternate knitting systems. At the end of each blank the fashioning needles and jacks can be returned to the inactive tracks by cams 79, 80 (see also cam 55 in the dial - Fig. 3). A thread change in the yarn feed mechanism 84 can be initiated by cam 99 acting via a link 101. A pawl (123 Figs. 16, 17 not shown) at the top of the link turns a ratchet (124) provided a detent (120) has been released by an eleotromagnetically held catch (121). The lower part of the needle cylinder may be stepped at 150 to provide a fulcrum for the jacks.

Title: Apparatus for creating protective coatings on carbon articles
IPC: B05B13/02
Filed: 1971-10-22
Abstract: 1378384 Coating carbon articles BRITISH STEEL CORP 20 Oct 1972. [22 Oct 1971] 49261/71 Headings B2E and B2L A protective coating is applied to the surface of a carbon article in a single operation by spraying aluminium in molten state on to the surface and immediately spraying a refractory material on to the aluminium coating so formed. The two materials may be applied from spray heads located alongside each other and moved relatively to the carbon surface, the distance apart of the spray heads being sufficient to ensure that there is no interference with the two sprays and that heat from the molten aluminium does not dry out the refractory material before it reaches the surface of the carbon article. Preferably the refractory spray is a pneumatic spray and a thickening agent such as sodium carboxymethyl cellulose is preferably present in the refractory coating composition. A typical refractory material comprises aluminium powder, titanium dioxide, silicon metal powder, silicon carbide, boric acid, ferrochrome, bichromium trioxide and a zirconium silicate. In an apparatus described the carbon electrode 10 to be sprayed is supported in a lathe and grooves 12 are formed on the electrode in a preparing process. After spraying, the aluminium and refractory may be fused by electric arc and a further applicator made. After fusing again an appliction of aluminium and graphite may be applied. The electrode surface is then sprayed with aluminium by an electric arc process in which aluminium rods 13 are fed into the gap 14 between the arc electrodes 15 and atomised, the. aluminium being blown by air jet 16 on to the carbon electrodes surface. The refractory is delivered through spray 17. During spraying the electrode is slowly rotated and a band of aluminium about one inch wide is sprayed to form a continuous spiral coating of aluminium on the electrode surface. The distances both vertical and horizontal separating the two sprays are variable and dependent upon the rate at which the spray operates. The aluminium spray and refractory spray heads are mounted on a carriage 20 supported on a rail 21 and by a wheel 22 running in another rail 23. The carriage is traversed automatically by a lead screw 24. The refractory spray is provided with a pneumatic spray gun having heads 17 and pipes 18 for the supply of air and 19 for the supply of refractory.

According to the invention, the receiver also includes an envelope detector 123; the output from this only includes a positive noise pulse 60, Fig. 2c and this is extracted by a threshold detector 125 and applied to a blanking circuit 127 which, for a period of the noise pulse, clamps the output from the synchronous detector 109 to a predetermined value, e.g. black or grey level (Figs. 2e, 2f, 2g, not shown). The sound recovery circuits 121 may, as shown, be fed from the envelope detector 123, or alternatively from the output of the blanking circuit 127, which may also feed the sync separator 111; as shown, the latter is fed directly from the synchronous detector 109. Detector circuits.-The video signal is fed from the I.F. amplifier to a bandpass filter 201, Fig. 3, having a balanced output feeding into the emitter-followers 203, 205. Emitter-followers 203, 205 feed via amplifiers 209, 211 a sharplytuned circuit 213 which extracts the carrier frequency and feeds it via cascaded emitterfollowers 215, 219 and 217, 221 respectively to one pair of inputs of the synchronous detector 225: the modulated signal is fed to the other pair of inputs from the emitter-followers 203, 205. The blanced output at terminals 227, 229 from the synchronous detector 225 are fed to the two inputs of an amplifier 231 which produces an unbalanced output via emitterfollower 233 which is fed via resistor 261 and emitter-follower 263 to the video output terminal. I.F. signal from emitter-follower 205 is also fed via an amplifier 235 to transistor 239 which constitutes the envelope detector: the output from this is applied via emitter-follower 245 to threshold circuit 250. Threshold circuit 250 is so adjusted that its output comprises noise pulses and these are fed to transistor 260 which, during the noise pulses, clamps the base of emitter-follower 263 to a predetermined potential.
