Title: Improved treatment of natural and artificial fibres
IPC: C08L89/00
Filed: 1938-01-26
Abstract: 509,852. Artificial silk &c. ; treatment of natural and artificial bands, fibres etc.; dyeing; resinous condensation products. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.). Jan. 26, 1938, No. 2513. [Classes 2 (ii), 2 (iii), and 15 (ii)] Natural and artificial fibres or threads, artificial bands or the like are given a woollike character by incorporating in the fibres a resinous product prepared by causing an aromatic isocyanate or isothiocyanate to react with a mixture of a protein and a nitrogenous base or with a product of the reaction between a protein and a nitrogenous base. This resinous product may be incorporated with the fibres by producing it on the fibres or by impregnating the fibres with a solution or emulsion of the product. Artificial fibrescontaining casein require treatment only with the nitrogenous base and the aromatic isocyanate or insothiocyanate. Instead of being incorporated in already-made artificial fibres, those of the resinous products which are derived from a protein, an aromatic isocyanate or isothiocyanate and a nitrogenous base other than ethylene imine, a homologue thereof or a polymer of any of these imines may be dispersed, in finely pulverized form or in the form of a solution in an organic solvent, in the spinning solution from which the artificial threads are to be spun. The modified fibres, etc., obtained according to the process of the invention can be dyed, with wool dyestuffs, colours of very good fastness. In examples, (a) casein fibres are treated in turn with ethylene imine, and phenyl isocyanate, (b) various resinous products of the type referred to above are incorporated in viscose or cuprammonium spinning solutions. Specifications 501,653 and 505,976 are referred to.

Abstract: 620,945. Paper-bag machines. ROBINSON, Ltd., E. S. & A. DAVIES, K. W., and NICHOLAS, J. Feb. 3, 1947, No. 3218. [Class 94(ii)] A machine for making block bottom bags is provided with a nose-piece 33, for forming the bottom, having a table 62, facing the approaching bag tube, a vertical pillar 64 which has at least a portion displaced to one side of the centre of the line of bag approach, and two fingers 68, 69 which rotate on an axis or axes lying parallel to the line of approach of the bag tube. The fingers are placed one on each side of the nose-piece and are angularly displaced to press downwards two flaps 76, 77 of the bag bottom so that the edge of one overlaps the other, to which it is stuck. The rear edge 66 of the nose-piece is bent outwards to help the overlapping of the flaps 76, 77. Rolls 24, 25 have die and punch means to form a horse-shoe shaped cut in the web 23, drawn from a roll 22. This causes the bag to have a tongue 39, which is secured to the bag bottom, and a thumb notch 47 at the top of a bag to facilitate opening. The web is folded into a tube around a former 29 and a reciprocating bar 37 turns over the tongue 39 which has been forced up by a spring 40. The tube then passes between a cutting roll 32 and a fixed knife 44 where it is severed into bag lengths. The shape of the cut may be varied in different bags. Means to open the leading edge of a bag comprises a bar 48 with tongues 60, 61 which guide the bottom part of the tube under the nose-piece 33 and the upper part over the top of the table 62. The bar is reciprocated by linkage 55, 56 so that it is drawn backwards to clear the cutters 44, 45 during the tube-severing operation. A creasing bar 73 is reciprocated above the tube and below the nose-piece to cause the diamond-shaped bag bottom to fold over.

Filed: 1927-02-07
Abstract: 265,624. K. G. Farbenindustrie Akt.- Ges. Feb. 8, 1926, [Convention date]. Right to Patent relinquished. Respirators.- In respirators in which carbon monoxide is oxidized with the use of catalysts such as mixtures of metallic oxides, the deterioration of the catalyst through absorption of water is prevented by drying the gas by means of adsorptive substances in gel form. These substances eliminate also other impurities, such as hydrogen sulphide and iron carbonyl, which may injure the catalyst or be otherwise undesirable. Suitable substances are gels of silica, alumina, and stannic acid, and mixed gels or mixtures of gels may also be used. The adsorptive substance and the catalyst may be arranged in alternate layers, and the gas may be passed also through a layer of active charcoal. The catalyst may be revivified, if necessary, and the absorptive substance regenerated, by a current of gas, such as warm, air, applied in situ.
