Title: Improvements in or relating to the manufacture of artificial filaments, threads, films and the like
IPC: D01F2/28
Filed: 1932-07-19
Abstract: Filaments, yarns, fabrics, and the like, having a reduced liability to fading of colourations produced thereon, contain organic derivatives of cellulose which are insoluble in dilute caustic alkali and have amino groups in substituent radicles in such proportions that the nitrogen content of the materials in the form of such amino groups is not in excess of 1 per cent of the weight of the materials. In the case of filaments &c. having a basis of an organic derivative of cellulose, the amino groups may be introduced by way of the spinning solution, for example, a mixed cellulose ester or ether containing both unsubstituted ester or ether groups and amino-substituted ester or ether groups in the desired proportion may be dissolved and extruded in the usual manner.  Alternatively a spinning solution may be made up containing both unsubstituted cellulose esters or ethers, and also cellulose esters or ethers having amino groups in the substituent groups.  In the case of natural textile materials as well as artificial materials, filaments, yarns, fabrics, and the like may be impregnated with a solution containing the organic derivative of cellulose containing amino groups.  The impregnation may take place by immersing the materials in, or by passing them through solutions of the amino-substituted cellulose derivatives, or it may take place by spraying, or contacting with wicks, rollers, or the like.  Suitable amino-substituted organic derivatives of cellulose which may be used are those of Specifications 320,842, [Class 2 (ii), Cellulose &c.], 344,420, 344,480, 344,488, 346,806, and 394,722.  In an example, a spinning solution containing cellulose acetate and also the nitrogen-containing derivative of Example 6 of Specification 320,842 such that the nitrogen content is about 0.2 per cent of the total cellulose derivative present, is spun by a dry-spinning process.  The produce may be dyed with 1.amino - 4.methyl - amino - anthraquinone. In another example, cellulose acetate and the product of Example 1 of Specification 344,480 are dissolved to form a spinning solution containing 0.9 to 1 per cent of nitrogen based on the total weight of cellulose derivative.  Materials obtained therefrom may be dyed with 1.4-dimethyl-amino-anthraquinone.  According to the Provisional Specification, the nitrogen content of the materials, in the form of amino-substituted derivatives of cellulose, may be up to 3 or 5 per cent of the total weight of the materials.  Specifications 243,841, [Class 15 (ii), Dyeing, Processes &c. for], 340,541, 340,572, 355,726, 361,362, 361,381, and 373,628 also are referred to.

Title: Improvements in or relating to starting and reversing devices for multi-cylinder internal combustion engines
IPC: F01L13/00
Filed: 1927-08-08
Abstract: 289,304. Thege, E. O. P. Aug. 8, 1927. Starting; reversing.- In a pneumatic device for actuating the starting-air valves 8 of multicylinder engines for starting or reversing, a power accumulating device such as a spring 23 is provided between the valve and the piston 26 of the pneumatic device and a fixed abutment limits the working stroke of the piston 26, the tension thus imparted to the spring being such that the spring will open the valve when the pressure of the gases in the engine cylinder 7 has become equal to or smaller than the pressure of the starting air. As shown in Fig. 3, the starting valve 8 is normally closed by a spring 9 and compressed air is supplied from a receiver through a hand-actuated valve and a pipe 10. A gas-tight sleeve 18, movable longitudinally in a guide in the valve casing 6, is fixed between a flange 19 on the valve stem 17 and a sleeve 20 screwed to the spindle. Bearing on the sleeve 18 is the flange 22 of a sleeve 21 enclosing the spring 23, which bears at its upper end against a member 24 in which the stem 17 is slidable. The member 24 is retained by a cover 25 secured to the sleeve 21. On the admission of compressed air to the cylinder 27, the piston 26 and member 24 are forced downwards, compressing the spring 23 to such a tension that it opens the valve 8 when the pressure in the engine cylinder is equal to or less than that of the starting air. Compressed air is supplied to the cylinders 27 of the pneumatic devices through pipes 29, 40 - - 42 from a rotary distributing valve 44, Figs. 4 and 5, by which each cylinder in turn is connected alternately to the compressed-air supply and to the atmosphere. The valve rotates in a lining 31 in a casing 30, in which is a chamber 32 connected by a pipe 33 to the compressed-air supply and by ports 46 in the lining to a recess 45 in the valve 44. The outer end of the lining is open at 54 to the atmosphere, and intermediate openings in the lining lead through distributing channels 34 - - 37 to the pipes 29, 40- - 42. Inlet chambers 49, 50 in the valve are connected by passages 47 48 to the recess 45 for the admission of compressed-air to the channels 34 - - - 37 in turn, and outlet chambers 51, 52 are connected by passages 53 to the oulet 54 for the escape of compressed air. In the position of the valve shown, the chambers 49, 51 are in use; reversal is effected by shifting the valve axially to bring the chambers 50. 52 into use. The valve is driven from the engine shaft through toothed gearing.
