Title: Improvements in the manufacture of artificial silk or artificial spinning threads
IPC: D01F4/00
Filed: 1934-09-20
Abstract: In the manufacture of artificial silk or artificial spinning threads of wool-like character from alkaline cellulose solutions, particularly viscose, by the wet spinning process, wherein an albuminous substance of vegetable or animal origin is added, this substance is added to the solution shortly before spinning in order to avoid material decomposition of the albuminous substance. The substance may, for example, be added immediately before or during the de-aeration of the spinning solution, or may be intermixed continuously as the spinning solution passes from the spinning tank to the spinning machine, mixing devices of known type being employed to ensure thorough mixing without aeration. Suitable substances are albumin and casein, or other albuminous substance of sufficiently high molecular weight to be insoluble in the spinning solution. Substances which aid the albuminous substance to produce in the cellulose fibres the capacity for being dyed with acid wool-dyestuffs, e.g. the sulphate of zinc, magnesium, or aluminium may be added to the spinning bath.  The spun fibres may be after treated with formaldehyde.  In an example a viscose solution containing 7,5 per cent of cellulose and 6--7 per cent of alkali is mixed with a 5 per cent aqueous albumin solution shortly before spinning and while avoiding access of air so that the solution contains about 10 parts of albumin per 100 parts of cellulose.  The mixture is then spun, e.g. into a bath containing 13 per cent H2SO4 and 30 per cent Na2SO4.  Metal salts, e.g. 0,5 per cent of zinc sulphate may be added to the spinning bath especially when spinning fine threads.

Title: Siloxane molding compositions
IPC: C08L83/04
Filed: 1957-09-03
Abstract: A quick curing moulding composition comprises a filler, a curing catalyst and a siloxane of the average general formula <FORM:0822859/IV (a)/1> wherein b has an average value from 0.1 to 0.6, c has an average value from 0.95 to 1.3 and the R's are alkyl and aryl radicals, the molar ratio of alkyl to aryl radicals being between 1 : 1 and 5 : 1.  The siloxane is made by hydrolysing the required silanes under conditions minimizing concurrent intermolecular condensation and partially condensing the hydrolysates with a weak N-containing base, e.g. ammonia or an amine, and grinding or dicing the resulting solid polymer.  The hydrolysis is conducted below 65 DEG  C. and if the starting silanes are chlorosilanes, the hydrolysis is effected in a large excess of water containing an acid acceptor, e.g. an alkali or alkaline earth metal carbonate. The compositions may be made by dry or wet blending of the pulverized siloxanol, e.g. in amount of 20 to 50 parts (by weight), 50 to 80 parts of a filler, 0.1 to 2 parts of curing catalyst, 0.5 to 3 parts of lubricant and optionally pigments or colourants.  Fillers specified are silica, clay, mica, glass fibres, asbestos, metal fibres or powder, cellulosic fibres, synthetic fibres and ion oxide. Curing catalysts specified are Ca and Zn stearates, triethanolamine, diethylamine and the adduct of ethylenediamine and formaldehyde, with or without catalyst accelerators, e.g. Ca(OH)2, BaO, MgO, ethylenediamine - benzaldehyde adduct, diphenylguanidine, and Pb and Al stearates. Lubricants specified are stearic, palmitic and oleic acids, their Ca, Al and Zn salts and natural and synthetic waxes.  In a typical process Example (1) a mixture of dimethyldichloro-, methyltrichloro- and phenyltrichloro-silane was added slowly to a slurry of NaHCO3 in acetone containing 1% of water, the temperature being kept at 30 DEG  C.; after the addition of 4 ccs. of distilled water and stirring for 40 minutes the mixture was filtered and the filtrate was mixed with a toluene solution of triisopropanolamine and concentrated by heating under reduced pressure to give a molten residue which was discharged into a cooling pan.  The resulting clear, white, grindable resin had a gel time of over 600 secs. at 150 DEG  C., which was reduced to 29 secs. by the addition of ethylenediamine-formaldehyde adduct.  In a typical composition, Example (28) the siloxanol of (1) was ball-milled with ethylenediamineformaldehyde adduct, Ca stearate, diatomaceous earth, heated on rolls at 100 DEG  to 150 DEG  C. to form a smooth sheet which, after cooling, was granulated and then moulded under pressure at 150 DEG  to 185 DEG  C.

Abstract: 603,502. Making collapsable tubes. BOGOSLOWSKY, B. Oct. 22, 1945, No. 27729. [Class 83 (ii)] [Also in Groups V and XVII] A collapsable tube is made from a preformed blank 25 having an integral shoulder 26 and an elongated neck part, by first subjecting the neck part to a longitudinal pressure and then to an internal radial pressure further to compress the neck material and, when the neck is to be screw - threaded, force it into the screw-thread part of a hinged two-part die 6. The tube is mounted on a mandrel 1 which has an internal plunger 15, having parts of varying diameter, that can be moved vertically by a rack and pinion 17, 18. The die 6 has an upper cavity, in which the mandrel fits, and a lower cavity in which a bushing 10, fixed to a platen 8, slides. The bushing 10 has a bore in which the thinnest part of the mandrel slides. To apply the longitudinal pressure, platens 8, 8<SP>1</SP> are brought together causing the mandrel to move down into the die and grip the shoulder 26, and the bushing 10 moves up to compress the neck material. Stiff springs 9 are provided between the platen 8<SP>1</SP> and the die to ensure that the shoulder 26 is gripped before the longitudinal pressure is applied. A final forming pressure is applied to the shoulder by the platens after the springs 9 are fully compressed. To apply the radial pressure, the plunger 15 is lowered, causing the part 15b to move into the neck of the tube and expand it radially. A rubber gasket 4 is provided on the mandrel to prevent damage to the shoulder of the tube. The plunger and die may have heating and cooling means. The blank 25 is made according to the method and of any of the materials described in Specification 587,018. The materials include metal foil.
