Abstract: 1,202,882. Coating apparatus. O. A. BECKER. 8 Sept., 1967 [21 Sept., 1966; 11 Nov., 1966; 7 Jan., 1967], No. 41049/67. Heading B2L. [Also in Division B3] Insulating material forming a coating on sheet metal members is removed in circular or elongated areas by milling, rasping or grinding to permit resistance welding of the members and subsequent to welding the areas are re-coated. A machine for applying adhesive tape to the bare welded edges 192a, 193a Fig. 51 of a workpiece comprises a casing 305 having inclined slots in which are mounted the shafts 195a, 195b or rollers 190a, 190b urged together by springs 194. A plate attached to the casing carries a reel for adhesive tape 191 which is led over a grooved roller and past the rollers 190a, 190b to a tensioning means, tape cutters being arranged on each side of the casing. In operation the edges 192a, 193a are pushed between the rollers 190a 190b, the tape being thus folded over the edges and the machine is moved relatively to the edges. In another use of re-coating strip, a folded strip is placed over the bare edges and a device having rollers pressed together is moved along the edges. An apparatus for re-coating circular bare areas comprises a cylindrical reservoir (322a) Fig. 55 (not shown) containing a pasty substance pressed by a piston into a distribution chamber. The welded edges having the bare areas are pressed into a slot in the chamber between spring pressed sliders to be re-coated, the sliders scraping off excess pasty substance in withdrawal of the edges. The substance may be dried by a heated air flow. An apparatus for spraying lacquer on the bale areas comprise a motor driven trolley mounted by rollers 920, Fig. 57, on a rail 919 and carrying on a pivot 925 a reservoir 921 and a spray nozzle 933 supplied with compressed air. A V-shaped scraper 928 is mounted on the trolley to scrape lacquer into the areas to be coated. In one modification, instead of a spray nozzle, a broad nozzle for pasty materials is employed and in another modification a sponge is used. In a device for applying an adhesive tape of coating material a reel 943, Fig. 63, is provided on one end of a lever having a presser roller 944 on its other end, the roller being urged away from the work by a spring and towards the work by a pneumatic cylinder 946.

Abstract: 1514039 Delay measuring by correlation THOMSON-CSF 7 Oct 1976 [10 Oct 1975] 41827/76 Heading G1U A system of the type in which the phase lag # between a received cyclically recurring pulse-coded signal S2, Fig. 1, (for example, an echo signal in a radar system) and a transmitted signal S 1 of which the received signal is ideally a perfect copy, is determined by correlating 4, 5, the received signal with two locally generated signals S3, S4, each of which is a copy of the transmitted signal but shifted in phase therefrom by lags of #1 and #2, where #2-#1 is constant, by subtracting 6 the resulting correlation signals to produce a difference signal S5 having an amplitude-lag characteristic as shown in Fig. 2, in which the amplitude axis is drawn through the value #3 of # and not at the origin of # which is on the far left, and by adjusting the lags #1 and #2 so that the difference signal S5 is maintained zero, which means that the unknown phase lag # has the value #3 as shown, given by #3 = #1 + ¢ (#2-#1) is characterized in that this lag is determined by producing 9 a reference pulse S6 at a particular position within each cycle of the transmitted signal and a data pulse S7 at the same position within the locally generated signal S3 (which is phase-locked to the received signal S2), delaying 12 the data pulse S7 by an amount equal to half the constant difference #2-#1, and measuring the time between the reference pulse S6 and the delayed data pulse S8 by counting 11 relatively high frequency clockpulses. As described a 15-bit pseudo-random signal (S1), Fig. 3a (not shown), is repeatedly produced and transmitted by a generator 1 driven by clockpulses (HE, Fig. 3a). The received signal (S2), Fig. 3f (not shown), which lags the transmitted signal S1 by # is correlated 4, 5, with two signals S3, S4 produced by a generator 7 driven by clockpulses (HR), Fig. 3c (not shown). The clockpulses HR are controlled by the difference signal S6 so that the lag # of the received signal S2 always lies between the lags #1 and #2 of signals S3 and S4 as shown in Figs. 3d and 3e (not shown) respectively. At a particular time within each cycle of the transmitted signal S 1 and the locally generated signal (S3), pulses (S6) and (S7), Figs. 3g and 3h (not shown), respectively, are produced, the pulses S7 are delayed to give pulses (S8) Fig. 3i (not shown), and the phase lag between pulses S6 and S8 is measured by counting clockpulses Fig. 3j (not shown). The clockpulse generator 8 may include means e.g. Fig. 5 (not shown) to effect the initial acquisition of the received signal S2 to bring its lag # into the operative portion of the characteristic shown in Fig. 2.
