Title: Improvements in method of obtaining spinning fibre from unretted plant stalks and articles obtained thereby
IPC: D01C1/02
Filed: 1931-09-03
Abstract: 379,515. Degumming fibres. LOWRY, G. A., 79, East 130th Street, New York, U.S.A. Sept. 3, 1931, No. 24798. [Class 120 (i).] Fibres are obtained from plants by separating the woody core and then treating with a watery solution of glycerine for 10-20 minutes to disintegrate the gums. The core of the unretted plant stalks is preferably first broken into short lengths ; the fibres are then separated from the woody core and treated with a 6-12¢ per cent solution of glycerine, preferably in soft water. The fibres are freed from excess solution, e.g. by centrifuging, and then air dried.

Abstract: 937,266. Moulding thermoplastic floor tiles. JOHN-MANVILLE CORPORATION. July 10, 1961 [April 4, 1961], No. 24824/61. Class 87(2). Vinyl, vinyl-asbestos or asphalt tiles are decoratively patterned, throughout the thickness by heating and calendering a layer of cut chips or particles into a coherent form. The chips are cut from one or more sheets 86 each of a different colour produced from a conventional mixer 1, heated mill rolls 4, 5, heated calender rolls 9, 10 and 13, 14 and cooler 18. The chip former 19 may comprise a hammer mill for irregular shapes or heater, extruder and cutter for more regular geometric shapes, e.g. discs, squares, cubes, tubes, spaghetti like particles &c. Different coloured and shaped chips are uniformly blended in mixer 20 and a uniform heated layer 21a is sheeted through heated rolls 25 and 26, with negligible residence time at the nip 27, and then calendered through heated rolls 31, 32 and 36, 37 to final thickness and surface. A cooler 41 is followed by cutter 42 which produces the final dimensions. Directional effects arising from the various rollers may virtually be eliminated by cutting and rotating sheet 21b through 90 degrees. One of the effects obtainable, Fig. 4, comprises a plurality of stripes 71, 72 intermeshed in a haphazard manner, the particles forming the layer 21a are comprised of rolls approximately “ inch diameter and of irregular lengths of from ¢ inch to 3-4 inches. Other effects are illustrated in Figs. 2, 3 and 5 (not shown).

Title: Improvements in or relating to methods of detecting surface discontinuities in articles
Inventor: FOREST TABER DE
IPC: G01N21/91
Filed: 1956-08-14
Abstract: 819,925. Detecting surface flaws. SWITZER BROS. Inc. July 9, 1957 [Aug. 14, 1956], No. 24834/56. Class 106 (2). [Also in Group XL (a)] A method of testing the surface of an article for the presence of a surface discontinuity comprises forming on the surface of the article an adherent film of a liquid penetrant containing a colouring matter susceptible to fading on exposure to ultra-violet light, exposing the surface to ultra-violet light for sufficient time to substantially destroy any colour in the penetrant on the surface, but not in that lodged in a surface discontinuity and then inspecting the surface in a light which will render contrastingly visible any colouring matter remaining in a surface discontinuity. Suitable penetrants are stated to include kerosene, mineral spirits and light fuel oils. Less suitable penetrants include benzene, toluene, xylene, methyl ethyl ketone, isophorine, butyl acetate, amyl acetate and acids such as acrylic acid. Some of these latter are soluble in water and care must be taken, if a water wash is used to remove excess penetrant before leaving the films, not to use too vigorous a wash. Suitable dyes include that sold under the Registered Trade Mark " Fluorol 5GA," perylene and celliton brilliant yellow FFA, all of which fluoresce and are soluble in the above mentioned penetrants. The mixture may be applied in any suitable way, either to leave a thin film or else to leave an excess of liquid which may be removed by wiping or hosing with water. The inspection may be made under ultra-violet light, or a developer such as french talc may be applied to the surface which is then inspected under visible light.

Title: A method of obtaining aromatic and olefinic hydrocarbons
Inventor: EISENLOHR KARL HEINZ
IPC: C07C15/00
Filed: 1962-06-28
Abstract: Aromatic hydrocarbons are separated from feedstocks also containing olefins, but from which more unsaturated hydrocarbons have been removed, by solvent extraction with pyrrolidone or a derivative thereof.  The feed may be a cracked gasoline or low temperature carbonization gasoline.  The highly unsaturated materials are removed by fuller's earth, polymerization catalysts or, preferably, mild hydrogenation, e.g. using a nickel or palladium catalyst at below 100 DEG  C.  The solvent employed may be pyrrolidone or an N-alkyl, N-hydroxyalkyl or N-acyl derivative in amounts of 5-20 vols. per vol. of aromatics in the feed and the solvent may contain 15-30% of water. An anti-solvent is preferably used, e.g. a hydrocarbon fraction boiling below 60 DEG  C. the volume ratio of aromatics to anti-solvent being between 1.2 and 0.5 and/or an extract reflux may be used.

The bowl is divided by concentric cylindrical walls C, D, E into a number of compartments with openings F, G. H arranged so that the liquid travels in opposite directions in adjoining compartments. The liquid for treatment is supplied to the central pipe A, and as it passes outwards, light impurities are deposited on the exterior surfaces of the walls C, D, E and the heavy impurities are deposited on the interior surfaces. The purified liquid is led towards the axis through passages formed between the top plate J and the cover I, the flow being assisted by wings K and the liquid being discharged from the opening L. In a modification the liquid for treatment is supplied to the outermost compartment and the drum has a conical top plate ; the walls C, D, E may be of prismatic or conical shape and are arranged to fit between projections on the base of the drum. The channels U, V, Fig. 5, between the components are arranged to connect the mid points of the radial sections, so that the cleanest portion of the liquid passes on from each compartment.
