Patent GB-348625-A (GB)
IPC: D01F2/28
Filed: 1929-11-09
Abstract: Artificial filaments, yarns, bristles, straw, ribbons, films, &c., are prepared by extruding a solution of cellulose acetate or other organic derivative of cellulose in a volatile solvent, which solution also contains a non-solvent or precipitant for the organic derivative of cellulose.  The process is carried out by dry or wet spinning methods.  Suitable non-solvents or precipitants include fatty acids such as stearic or oleic acid; waxes, glycerides of fatty acids such as olein or stearin; petroleum hydrocarbons such as petrol, petroleum, paraffin, mineral lubricating oils, petroleum, or petroleum jelly or paraffin wax; aromatic hydrocarbons such as benzene, toluene or xylene; ethyl or methyl alcohol; water; polyhydric alcohols such as glycerine or ethylene glycol.  Mixtures of two or more non-solvents may be used.  An addition of 2 1/2 -10 per cent on the weight of the cellulose derivative is preferred.  The added substances may remain in the yarns or may be removed therefrom. Yarns may be reduced in lustre by treatment with hot water, the extent of such reduction depending upon the nature and quantity of the added substance.  Wet spinning may be conducted in water, kerosene, &c.  Suitable solvents include acetone, acetone and methyl or ethyl alcohol, chloroform, ethylene dichloride or methylene chloride and ethyl or methyl alcohol. Filaments &c. so produced are tough and pliable.  Yarns may be more highly twisted and more closely knitted than prior yarns; yarns and bristles may be formed into stronger knots; and straws and ribbons have improved plaiting qualities.  Examples are given of spinning solutions of cellulose acetate in (1) aqueous acetone with an addition of petroleum jelly, (2) ethylene dichloride-methyl alcohol with an addition of xylene, and (3) pure acetone with an addition of paraffin or petrol.

Abstract: 809,119. Artificial legs. HANGER & CO. Ltd., J. E., and DADSON, A. J. S. June 15, 1955 [Dec. 9, 1953], No. 34318/53. Class 81 (2). An artificial leg has a pelvic socket pivotally connected to a thigh portion by a side joint, the axis of the pivotal connection approximating to that of the natural hip joint, and means for preventing separation of the socket and thigh portion over a predetermined range of angular positions of the one relative to the other. An arm 3 of a bracket 2 secured on the outer surface of a metal pelvic socket 1 is pivoted to an arm 5 of a bracket 6 secured on the surface of the lateral aspect of an artificial thigh-piece 4. The arms 3, 5 forming the joint have aligned apertures which receive a sleeve 7, which threadedly engages the arm 5 attached to the thigh-piece 4 and is provided with a flange 8 to keep the arms 3, 5 together. Graphite impregnated discs 10 are arranged between the moving surfaces of the joint. A tuber plate 11 on the pelvic socket 1 bears against a leather covered track plate arranged across the upper end of the thigh-piece 4. A lever 13 attached to the arm 5 secured to the thigh-piece 4 is spring urged to engage a shoulder (not shown) on the periphery of the arm 3 in order to lock the joint against pivotal movement. When the wearer desires to sit, lifting of the lever 13 permits the joint to be unlocked. A stop 17 is provided on the arm 5 secured to the thighpiece 4 to engage a " flat " (not shown) in order to limit pivotal movement of the thigh-piece 4 in a rearward direction. The head 19 of a stud 20 attached to the track plate 12 engages a slot in the tuber plate 11. The slot is wider towards the rear so that when the wearer sits the head 19 is disengaged from the slot 18. According to the Provisional Specification, the tuber plate may be in the form of a leather strip.

[Also in Division B6] An apparatus designed to aid teaching in reading or improve reading speed, comprises a web supply roll 108, and an advance roll 101 driven by a hand-wound spring motor 90 which draws the web past an observation station, and over a platen 233 formed with rounded side guides 235 and rounded ends 232. The spring motor 90 is connected by gears 16, 98 to the advance roller. A clutch 110 on the motor shaft 94 free-wheels during a winding action, but when the motor is driving, the clutch connects it to a speed control governor which can be set to give various speeds of travel of the web. The web may be wound back to the supply spool 108 by a handle 50, an automatic disengaging clutch 68, 70, 72 and gears 66, 82. The observation window above the platen has a reading guide line which is sloping a few degrees to allow for the travel of the web during reading from left to right. To compensate for the additional speed developed because of a full advance spool the lines may become progressively shorter or spaced further apart.

Abstract: The invention comprises azo dyestuffs of the formula <FORM:1101364/C4-C5/1> wherein R is an aromatic or heterocyclic radical in which the N atoms of the triazole group are in o-position to each other, R1 is an aromatic radical which is free of OH groups, the azo group and -N(R2)- being in p-position to each other, R2 is H or a substituent one X is an SO3H radical, the other X is hydrogen or SO3H, Z is an acyl radical, and n is a whole number.  The may be obtained by condensing an aminoazo dyestuff of the formula <FORM:1101364/C4-C5/2> with a mono- or polyfunctional acylating agent. Specified acylating agents include acetic anhydride, acetyl chloride, propionyl chloride maleic anhydride benzoyl chloride, phenyl isocyanate phosgene, fumaric acid dichloride terephthalic acid dichloride, benzene sulphonyl halides, and those which contain halide substituents after acylation, for example 2,3-dichloroquinoxaline-6-carboxylic acid halides or-sulphonic acid halo fatty acid halides, derivatives of unsaturated aliphatic carboxylic or sulphonic acids, 1-(sulpho- or carboxy-aryl or-alkyl)-4,5-dihalo-6-pyridazones, 2,6-dichloropyrimidine-4-or-5-carboxylic (or-sulphonic)acid halides, triazine halides and derivatives thereof, and pyrimidine tri- and tetrahalides when the acylating agent contains a nitro group this may be reduced and subjected to further acylation.
