Title: Process for the manufacture of improved artificial silk, in particular cellulose acetate silk
IPC: D01F2/28
Filed: 1929-04-12
Abstract: 309,558. I. G. Farbenindustrie Akt.- Ges. April 12, 1928, [Convention date]. Right to Patent relinquished. Yarns, treating with liquids.-Artificial silk prepared from organic acid esters of cellulose, for example acetate silk, is improved by charging the finished silk with acetic acid, subjecting it to stretching and removing the acid while maintaining and increasing the tension. Threads treated in this manner possess greatly increased dry and wet tenacities. The treatment can be applied to twisted or untwisted skeins or finished fabrics. In an example, a skein of acetate silk made by the dry spinning process is impregnated with 40 per cent acetic acid; stretched to three times its original length; washed, whilst maintaining or increasing the tension, with acetic acid of increasing dilution, and finally with water, and then dried in the customary manner. Specification 277,089 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers to combining the process with the spinning process, and also to the employment of other organic acids, for example formic or propionic acids or mixtures of such organic acids. This subject-matter does not appear in the Specification as accepted.

Title: Explosives
IPC: C06B21/00
Filed: 1940-07-11
Abstract: 543,298. Explosives. WILLIAMS, W. P. (Western Cartridge Co.). July 11, 1940, No. 11578. [Class 9 (ii)] Propellant powder grains are produced by the autogenous adhesion of fine particles of gelatinized nitrocellulose dust which is effected by agitating and heating the particles in a water slurry to which is added, as by spraying, a solvent or plasticizer not miscible with the water. Volatile solvent is subsequently removed by evaporation ; but, non-volatile, explosive plasticizers such as nitroglycerine, dinitrotoluene, or trinitrotoluene may be used, in which case the grains are submitted to a centrifugal or wring- ing treatment. The degree of agglomeration as well as the dimensions and physical characteristics of the grains may be controlled by the extent of agitation and emulsification. Before final drying, the grains may be given a coating, comprising, e.g. nitrocellulose, to modify the burning characteristic, and to render the powder non-hydroscopic. A deterrent such as dibutylphthalate may be embodied in the coating. Partially deteriorated cannon powder may be submitted to the process by first reducing to the required dust form and then treating in a slurry with a solvent such as ethyl acetate and suitable deterrents. A neutralizer, such as calcium carbonate, may also be added. Specification 5865/93, [Class 9], is referred to.

Title: Automatic adjustment and safety device for hydraulic brake system
IPC: B61H15/00
Filed: 1953-04-28
Abstract: 720,935. Hydraulic brakes. TECNO TRADE ANSTALT. April 28, 1953 [July 23, 1952], No. 11764/53. Class 103 (1). A device for insertion in a hydraulic braking system for vehicles between the master cylinder 1 and the wheel cylinder 11 whereby the brake shoe release clearance is automatically adjusted and a faulty pipe line may be isolated, comprises a cylinder 6 within which is a differential piston 17 subject on its left hand side to pressure from the master cylinder 1. When the master cylinder is actuated the piston 17 and its integral piston rod 17 are moved to the right compressing liquid in a chamber 20 which is forced through passages 43 and 44 in the piston rod and conduit 7 to the brake cylinders. If the shoe clearance was initially correct and equal to a distance "a" the abutment 37 on the piston rod would meet a spring-loaded washer 28 and a passage 36 leading to a spring loaded valve 33 would just reach the sealing sleeve 24 at the same time as the shoes engage with the brake drum. If the brake shoe clearance was initially greater than the distance "a ", after the shoes have engaged the drum, increased pressure applied to space 20 will be released past the ball valve 33 to chamber 18 on its other side. If the brake shoe clearance was initially greater than distance "a" the abutment 37 will engage and carry with it the washer 28 compressing spring 25. The pressure in chamber 18 to the left of piston 17 therefore rises to a value at which liquid is transferred past the sealing sleeve 21 to chamber 20. In each case when the master cylinder pressure is released, the pressure in the brake cylinder is also released as soon as the piston 17 has moved back sufficiently to uncover port 36 so that the brake shoes are always at a clearance " a." If a leak should occur in a pipe line between the device and a brake cylinder, the loss of pressure in chamber 20 enables spring 26 to force members 22, 24 to the left sealing off port 43 and thus the defective lines. 'An application of the device to tractor-trailer units is described.
