Title: Improvements relating to the manufacture from continuous filaments of a continuous product containing staple fibre
IPC: D01G1/10
Filed: 1935-03-06
Abstract: 453,433. Stapling continuous filaments. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and TAYLOR, W. I., c/o British Celanese, Ltd., Spondon, near Derby. March 6, 1935, No. 7073. [Class 120 (iii)] A continuous product containing staple fibres is produced by passing a bundle of continuous filaments 14 between a pair of rollers 1, 2, Fig. 1, in pressure contact one at least of the rollers having a cutting surface and one roller being positively driven while a braking force is applied to the other so as to cause it to rotate at a lower peripheral speed than the positively driven roller. The bundle of filaments 14 is drawn through the rollers 1, 2 by the rollers 3, 4 the roller 3 being grooved and driven at a higher speed than the roller 1. The latter is formed with sharpedged flutes which convert the continuous filaments into staple fibres. The bundle of staple fibres may then be twisted and.wound on to a package 18 by a cap spinning device 17. The roller 2 rests upon and is driven by frictional engagement with the roller 1. It is braked so as to rotate at a slower speed by a cord 22 passing over a brake drum 21 and weighted at 25 the run of the cord being such that it does not increase the pressure between the rollers 1, 2. In a modification springs 26, 27, Fig. 2, are pressed approximately horizontally against the friction drum 21 by adjustable screws 31 or a brake shoe is pressed against the drum by a pivoted lever weighted at its end. In other modifications in which the braking means directly affects the pressure between the rollers 1, 2, weights 42 may be added above a carrier weight 41 engaging the roller spindle 40, Fig. 4, or a presser member 43, Fig. 5, carrying weights 44 is provided in contact with the roller 2. Alternatively the roller 2 is engaged by a roller 47, Fig. 6, carried by a lever 48 which is loaded at 51. Rotation of the roller 47 is controlled by a check spring 53. Specifications 424,683 and 424,830 are referred to.

Filed: 1977-02-22
Abstract: Process for the preparation of d,l-5-methyltetrahydrofolic acid and its salts of the formula 1 in which X is hydrogen, an alkali metal or the equivalent of an alkaline earth metal, by reduction of folic acid with NaBH4 and methylation of the tetrahydrofolic acid obtained with aqueous solutions of formaldehyde and sodium borohydride in an inert gas atmosphere. The process is simple and can be carried out without separation of intermediates while carrying out the process steps successively in the same reaction vessel. The final products are obtained in a yield of more than 80%, relative to folic acid employed, in a purity of more than 99%. The compounds of the formula I obtained are non-toxic, stable at physiological pH and suitable for the preparation of liquid or solid pharmaceutical compositions for any type of application in human therapy. Such compositions exhibit haematopoietic action, hepatoprotective and antineoplastic action. <IMAGE>

[Classes 51 (ii) and 55 (i).] A vertical carbonization retort has carbonization, intermediate, and cooling zones A, B, C respectively, Fig. 4, steam inlets r, s being provided to the cooling zone in which is a coke discharge chamber D equal in capacity to one half, or other aliquot part, of the cooling zone which is proportioned to hold the coke from a complete charge in the carbonization zone. It thus takes two or more emptyings of the discharge chamber D to discharge the cooling zone, and allow the whole of the charge in the carbonization zone to occupy the cooling zone, Fig. 7. The contents of the intermediate zone B are at the bottom of the coke discharge chamber and resting on the discharge door p, which is never unduly heated, when hot coke falls into the intermediate zone from which a supply of water gas is always ensured. The discharging means comprises a gate d attached to a hinged wall e, and operated by a rack and pinion g, f, gastight casings i, j being provided. A discharge door k has a curved surface n on which rests a protector plate p. During discharge, Fig. 4, the wall e is swung aside, and the door k rotated to allow the plate p to drop. In a modification, the capacity of the coke discharge chamber is varied by the provision of walls adjustable towards or away from the opposite wall, or the wall e may have a pivot at h, Fig. 11, which is adjusted by a screw h<1>.
