Title: Improvements in hydraulic controlling means for spring hammers
IPC: B21J7/12
Filed: 1949-10-03
Abstract: 665,722. Power hammers. ROUCKA, E. Oct. 3, 1949 [Oct. 22, 1948], No. 25396/49. Class 83 (iv). Hydraulic controlling means for a spring hammer in which a strokeadjusting member 7 is subjected, when in operation, to varying reaction forces from a hammer-driving rod and lever mechanism comprises a hydraulic servomotor 10 fed from a store of liquid under pressure in a vessel 30 by a pipe'19 equipped with a non-return valve 20, the servomotor being so dimensioned that the force exerted by it is less than the maximum value of said reaction forces. The hammer driving mechanism shown is identical with that described in Specification 665,717, and the hammer stroke is adjusted by moving the member 7 by means of a pedal 27 and linkage 24, 25, 26. When a slide-valve 18 is in position to close the connection between the pipe 19 and the servomotor 10 the latter acts as a hydraulic brake and the reaction forces exerted by the movement mechanism are insufficient to move it. On depressing the pedal 27 the slide valve 18 is moved to the right and liquid is admitted to the right of the servopiston 9 from the pressure vessel 30, to exert a pressure less than the maximum counterpressure exerted by the reaction forces of the movement mechanism, so.that the piston 9 and the adjusting member 7 are moved to the left in a series of movements, during the intervals when the liquid pressure can overcome the said counter-pressure, until the valve 18 is returned to its original cut-off position. During the periods when the maximum counter-pressure is exerted the piston 9 is prevented from moving to the right by the closing of the non-return valve 20.

Title: Improvements in colouring cellulose ester or ether textile materials
IPC: D06P1/22
Filed: 1947-09-26
Abstract: Textile materials of cellulose esters or ethers are mechanically impregnated with an aqueous suspension of an indigoid vat dyestuff, then impregnated with an aqueous solution of a formaldehyde sulphoxylate made alkaline with a hydroxy aliphatic amine, steamed to reduce the dyestuff to the leuco form and the latter is finally oxidized back to the parent dyestuff on the fibre.  The dyestuff is made up into an aqueous suspension, preferably with a dispersing agent of the alkyl sulphate type, and applied to the material by padding or other mechanical means. The material is then preferably dried, and treated with aqueous sulphoxylate (e.g. sodium formaldehyde sulphoxylate in 2-15 per cent w/w) containing the hydroxy amine (2-15 per cent w/w); this treatment may also be by padding.  Diethanolamine is the preferred amine, but mono-or tri-ethanolamine may also be used, or triisopropanolamine.  After steaming to reduce the dyestuff to the leuco form and fix the latter on the fibre, re-oxidation may be effected with an acid oxidizing agent such as sodium dichromate and acetic acid; sodium perborate or hydrogen peroxide may be used instead.  The material is then soaped, rinsed, dried and finished in the usual way.  The dyeings are stated to be fast to light, gas, rubbing and washing.  The process is applicable to fabrics, yarn or staple fibre of cellulose acetate or other ester or ether.  Suitable dyestuffs are mentioned.  An example is given of the treatment of cellulose acetate according to the process of the invention.
