[Also in Division D1] A wear resistant non-porous rollable film used in the production of laminates is produced by impregnating a stable fleece of fibres substantially all of which are at least 1 cm. long in which the fibres of the fleece are either not bonded together or are bonded together by an impregnated bonding agent, with an uncured or incompletely cured urea-, phenol- or melamine-formaldehyde resin in an amount such that the fibre resin ratio by weight is 1 : 0À4 to 1À2 and then heating the impregnated fleece under pressure to cure the resin and compress the impregnated fleece to render it non-porous, its final thickness being 0À1-0À3 mm. The fibres of the fleece may substantially all be continuous or may substantially all be staple fibres or mixtures thereof may be used, and may be of hair, cotton or synthetic polyamide or polyester fibres. If the fleece, which may have a fibre weight of 30-200 gms. per square metre, is composed of continuous filaments it may be adequately stable although it may be bonded with a thermosetting resin but fleeces of staple fibres are normally bonded with a thermosetting resin, e.g. a polyacrylate, prior to impregnation with the urea-, phenol- or melamine-formaldehyde resin, the amount of bonding agent used preferably being 0À5-1 part by weight per part by weight of fibre in the fleece. After impregnation, e.g. with an aqueous dispersion of the resin the fleece may be dried at a temperature below the curing temperature of the resin and then heated at 120-160‹ C. under a pressure of 200 Kg./cm.<SP>2</SP> between a belt and hot rotating drum against which the belt is pressed. The fleece may be rendered decorative by printing it with a suitable pattern or a decorative layer, e.g. printed on paper, may be laminated with the fleece in the rollable film. may be bonded directly to a smooth wooden or other support surface after the resin has been cured.

Title: Improvements in or relating to the manufacture of organic solvent soluble cellulose ethers
IPC: C08B11/00
Filed: 1945-04-09
Abstract: Organic solvent soluble cellulose ethers are prepared by etherifying alkali cellulose with an etherification agent in the presence of a liquid paraffinic hydrocarbon diluent which has been purified so as to be substantially free from aromatic and unsaturated constituents and which is present in an amount sufficient to ensure that the fibrous form of the alkali cellulose is maintained throughout its conversion to cellulose ether. Examples of paraffinic hydrocarbons are kerosene and ligroin.  The resulting fibrous cellulose ether is separated and washed.  It may be bleached in an aqueous medium such that its fibrous condition is preserved throughout.  In an example, fibrous alkali cellulose is treated with ethyl chloride in the presence of a purified paraffin fraction (b.p. 200 DEG  C.) in an autoclave at 130 DEG  C. for 4 hours, separated, washed with water and bleached with an aqueous solution of sodium hypochlorite.  The product is insoluble in hot and cold water, but soluble in 80 per cent toluene with 20 per cent butanol.

Title: Filamentary material inspection apparatus
IPC: G01N33/36
Filed: 1963-03-05
Abstract: 1,037,302. Testing yarns. BORG-WARNER CORPORATION. March 5, 1963 [March 14, 1962], No. 8810/63. Heading D1F. [Also in Division G1] An apparatus for inspecting filamentary material 5 such as a moving yarn, comprises optical means 1 which forms in a beam of radiation such as infrared radiation, a shadow image of a length of the filamentary material 5 and a shadow image of a reference element 6, the images being generally parallel and spaced from each other, detector means such as a lead sulphide photo-cell 21, and means 10 for alternately projecting at regular time intervals each said shadow image on to the photo-cell 21 whereby the output of the photo-cell 21 is related to the ratio of the respective diameters of the filamentary material 5 and the reference element 6. As shown infrared radiation from a resistance element 2 is directed on to the yarn 5 and the reference element 6 by a collimating lens 3 and the resulting shadow images are focussed in the region of a mirror 11 which oscillates under the action of a C-shaped magnetic core which is energized by an A.C. coil 15 thus causing permanent magnets 13 to oscillate and so move the mirror 11. The shadow images are thus alternately scanned across a sensitive portion 21a of the photo-cell 21. The apparatus is initially adjusted so that the total area of the sensitive portion covered by each of the shadow images is constant when the diameter of the yarn 5 equals that of the reference element 6. The detector 21 is connected as shown in a bridge circuit 20 fed by a constant D.C. source 24 and the circuit is initially balanced to null by adjustment of a resistor 23. As the mirror 11 oscillates any difference in the diameters of the yarn 5 and the reference element results in one of the shadow images striking the sensitive portion 21a of the photo-cell 21 being larger than the other thus causing an A.C. signal to appear at the output of the bridge 20. This signal is fed through an amplifier 25 to a phase sensitive demodulator 26 whose output is connected to a meter 27 which indicates whether the yarn 5 is larger or smaller than the reference element 6. To increase ease of adjustment of the system the photo-cell may have means to mask the corners of its sensitive area to provide a triangular sensitive area (Fig. 4, not shown). In a further embodiment (Fig. 3, not shown) the reference element is placed between the focussing lens 4 and the mirror 11. In this last embodiment the reference element may take the form of a wire or as shown in Fig. 5, a thin flat ribbon 71 suspended between the ends 70 of a support means so that by rotating the support means the width of the shadow image produced by the ribbon may be adjusted for example from W 1  to W 2 . The output from the demodulator may also be connected to a chart recorder 28 and an audible or visual alarm which operates if the yarn breaks.
