Title: Improvements in or relating to ornamentation of fabrics
Inventor: PARKER CHARLES SCHWABE
IPC: D06C23/04
Filed: 1952-11-15
Abstract: 763,933. Ornamenting fabrics and paper. BLEACHERS' ASSOCIATION, Ltd., and BRADFORD DYERS' ASSOCIATION, Ltd. Nov. 13, 1953 [Nov. 15, 1952], No. 28885/52. Drawings to Specification. Classes 42 (1) and 96. [Also in Group XV] Fabrics which are capable of being extended, such as textile fabrics, paper, leather and those composed wholly or partly of fibrous or plastic materials, are ornamented by subjecting at least one region of the fabric to stretching, other adjacent regions being continuously or intermittently permitted some freedom from stretching whereby the stretched or extended region or regions becomes or become raised from their normal state of flat alignment, and ruffles, ribs, frills or like variations of shape are produced. The stretching may be effected by operating a compressive shrinking machine in reverse ; the machines disclosed in U.S.A. Specification 2,021,975, when adapted as disclosed in Specification 752,191 are suitable. The selective extension may be fixed by the application of heat, 'in the case of thermoplastic fabrics, by pre-treatment with resins or other fixing agents which are set by heat during or after the extending process, or by treatment with chemical reagents. Textile fabrics composed wholly or mainly of cellulose acetate may be pre-treated with aqueous solutions of swelling or plasticizing substances, dried after removal of excess solution, submitted to the ornamenting process at a suitable temperature, and washed to remove the. swelling or plasticizing substance. Certain fabrics may be shrunk to below their normal length before subjecting them to localized stretching. Fabrics may be coloured during ornamentation by applying a paste containing colouring matter to the belt, roller, shoe or plate of the machine, or suspensions of dyes may be applied to the fabrics and caused to be absorbed by contact with heated surfaces during ornamentation. Specifications 359,759, 371,976, 372,803, 402,087 and 529,579 are referred to in the Provisional Specification.

Title: Apparatus for Contactless Measurement of the Cross-Sections of Continuously Moving Elongated Material.
IPC: G01B11/10
Filed: 1967-06-22
Abstract: 1,192,206. Photo-electric diameter measurement. EXATEST-MESSTECHNIK G.m.b.H. June 22, 1967 [June 29, 1966], No.28946/67. Heading G1A. The diameter of a continuously moving filament 1, e.g. a wire, is measured by one or more pairs of photo-electric detectors 10, 11, the detectors of the or each pair being diametrically opposite one another relative to the ideal axis of the filament 1, and across each detector is scanned simultaneously an image of the crosssection of the filament formed by one or more pairs of lenses 3, 4 which are mounted upon a rotating ring 6, the lenses by the or each pair also being diametrically opposite one another relative to the filament ideal axis. The mean value of the sum of the length of pulses connected by detectors 10 and 11 is a measure of the diameter of the filament and is independent of whether the filament moves nearer to one detector than the other. To this end each detector drives a counter for the periods they are illuminated by the scan, the sum of the rates at which the counters are driven indicates the diameter. If the filament strays to the right or left as seen in Fig. 1a, one detector is illuminated by the scan before the other; this time lag is used as a correction to the measured diameter. The detectors may also be mounted upon a ring which rotates either continuously or oscillates, enabling the diameter to be measured in different directions. Alternatively this may be achieved by many pairs of detectors spaced around the filament. Several pairs of lenses may be mounted upon ring 6 to increase the frequency of measurement. Lamps 14 and 15 mounted on the rotating ring 6 illuminate the filament, although they are unnecessary if the filament is sufficiently luminous e.g. a hot wire.

Patent GB-748018-A (GB)
Title: A method for the chemical purification of natural graphite
IPC: G21C5/12
Filed: 1952-11-17
Abstract: Natural graphite is purified by passing a stream of chlorine or phosgene mixed with carbon tetrachloride or carbon monoxide through a reaction zone containing the impure natural graphite. Alternatively the impure graphite may be mixed with sodium chloride and the chlorine or phosgene used alone.  A suitable quantity of carbon tetrachloride is 1 per cent by volume of the chlorine or phosgene and of sodium chloride is 1 per cent by weight of the impure graphite. After completion of the above process, which may take place at an elevated temperature, e.g. 1000 DEG C., obtained by passing an electric current through the graphite, any remaining chlorine or phosgene may be removed whilst the graphite is heated to 7-800 DEG C. by a stream of air or by evacuation.  The Specification refers to silicates, mica, felspar, quartz and iron compounds, e.g. ferrous sulphide as ome impurities, and to the treatment of an impure graphite having a particle size of 0.1-0.5 mm.  Suitable apparatus includes rotary furnaces lined with lead or magnesite and shaft furnaces which may be continuously or intermittently charged, e.g. by means of a bucket wheel.
