Title: Improvements in or relating to the treatment of textile materials consisting of or comprising organic derivatives of cellulose
IPC: D01F11/02
Filed: 1931-04-15
Abstract: Filaments, threads, yarns, and the like consisting of or comprising cellulose acetate or other organic derivatives of cellulose, are subjected to treatment with a preparation consisting of or containing alkylolamines and/or their salts or soaps of aliphatic acids, but not containing fats or fatty oils. The alkylolamines employed may be the simple alkylolamines such as mono-, di-, or tri-ethanolamine or propanolamine, or substituted alkylolamines such as hydroxyethylaniline.  Suitable salts or soaps specified are those of higher fatty acids, e.g. capric, lauric, myristic, oleic, and stearic acids.  The alkylolamines and/or their salts or soaps of aliphatic acids may be applied to the textiles in solution or suspension in water or organic solvents, and particularly useful are solutions of about 20 to 35 per cent strength in mineral oils, especially paraffin oils.  The preparation may be applied to filaments or the like continuously with their preparation by dry or wet spinning processes, by passing the filaments over wicks &c., or by spraying with the preparation prior to winding or during winding from one package to another.  Alternatively, or in addition, in wet spinning processes, the preparation may be added to the coagulating bath. Similarly, the preparation may be applied to yarns during knitting, weaving, or other textile operation.  The process may also be applied to the treatment of staple fibres.  In examples, yarns of cellulose acetate or other organic esters of cellulose are treated with preparations comprising (1) a 20 per cent solution of triethanolamine oleate in American kerosene or paraffin, the triethanolamine oleate containing 2 per cent free oleic acid, (2) a 20 per cent solution of triethanolamine oleate in light Russian paraffin, and containing a slight excess of the alkylolamine, (3) a solution as in (1), but of 35 per cent strength.  In a further example, a cellulose acetate solution is extruded into a coagulating bath containing 5 per cent triethanolamine.  Specification 355,466 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) refers generally to processes for incorporating alkylolamines and/or their salts or soaps in or upon filaments, threads, yarns, and the like, and contains an example in which commercial triethanolamine is added to a cellulose acetate spinning solution. This subject-matter does not appear in the Specification as accepted.

Title: Improved method of grinding or crushing
IPC: B02C19/06
Filed: 1926-05-03
Abstract: 251,665. Barthelmess, E. May 2, 1925, [Convention date]. Mills and apparatus.-In grinding and crushing materials by pneumatic or hydraulic means, the materials in a container are subjected by means of air or liquid under high pressure to a rapid circular movement so that they are ground by centrifugal impact with the container walls. The fluid may be directed longitudinally into the grinding-chamber, and pieces of harder material such as flint stones may be added to the materials under treatment to increase the grinding action. Fig. 1 shows a pneumatic apparatus in which the air blast from a blower d is introduced longitudinally into the grinding-chamber b by a pipe p into which the materials to be ground are fed continuously at c. The air and finer particles pass through a sorting-device e surmounting the chamber b and through a pipe q into a cyclone separator f,from whence the air is returned by a pipe r to the blower. The size of the particles entering the pipe q is regulated by means of adjustable flaps h, and the coarser particles are returned to the chamber b through a central funnel s fitted with pivoted flaps q. Fig. 2 shows an hydraulic device in which liquid is fed tangentially into the grinding-chamber b by means of a pump i, the materials to be ground being fed directly into the chamber at c<1>. The overflowing sludge is received in a surrounding tray t from which a pipe q<1> leads to the upper part of a closed separator f<1> fitted with a series of superposed conical settling-rings m, The pump i draws its supply from the separator, and the ground materials which settle in the separator are discharged at l. In a modification, Fig. 3, suitable for the reduction of ores, the grinder is fitted with a bell mouth u, whence the sludge overflows on to a baffled settling-bed o where the ground ores are separated off.
