Title: Improvements connected with carpets or other woven pile fabrics and the means of manufacturing them
IPC: D03D27/00
Filed: 1949-09-21
Abstract: 670,127. Weaving warp pile fabrics; pile wires. CARPET TRADES, Ltd., and DAVIES, R. Sept. 15, 1950 [Sept. 21, 1949], No. 24220/49. Classes 142(ii) and 142(iv) Relief patterns are produced by a series of pile wires having depressions 21 at the places where pile of reduced height is required; the ends 22 of all the wires are of full height and may carry cutters 25. A normal wire (of full height), is inserted first, producing a row of uniform loops, followed by the series of pattern wires, producing low loops on the depressions 21 and full loops elsewhere. As each pattern wire is subsequently withdrawn, its end 22 brings all the loops on the wire to the full height, the extra yarn needed to convert low loops into full loops being robbed from the preceeding row of loops; the uniform loops of the preceeding row are thus changed into a replica of the loops on the wire just withdrawn; consequently, the relief pattern of two heights of loop formed over the wires is displaced one row for wards in the fabric.

Filed: 1945-09-21
Abstract: 598,098. Frequency modulation. BRITISH BROADCASTING CORPORATION, and GOURIET, G. G. Sept. 21, 1945, No. 24564. [Class 40 (v)] [Also in Groups XXXV and XXXVI] An oscillator V1, Fig. 1, has its frequency stabilized by a reactance valve V2 to whose anode are applied the oscillations from V1, and to whose grid is applied a voltage in phase quadrature with that on the anode and varying in sign and magnitude with the deviations of the frequency from V1. The oscillations are applied over an amplifier 10 to a bridge comprising three resistive arms R and a reactive arm C1, L1 tuned to the desired frequency so that the bridge is balanced. A deviation of frequency produces an out-of-balance voltage that is proportional in sign and magnitude to the direction and extent of deviation. When the capacity C is varied for frequency modulation, the arrangement provides negative feedback to obviate frequency drift and produce linear modulation, Fig. 2 (not shown).
