Title: Improvements in the treatment of filaments, fabrics, films and other materials having a basis of cellulose esters
IPC: D01F2/28
Filed: 1935-03-08
Abstract: Cellulose organic ester materials, particularly filaments, threads, ribbons, films, fabrics, and like materials, are subjected to saponification by means of a nitrogenous organic base having a swelling action on the cellulose ester, in presence of an aqueous solution of a substance which is not a saponifying agent but which diminishes the swelling of the cellulose ester.  The process is applicable to materials of cellulose acetate, formate, propionate, butyrate, or other organic ester or ether-ester of cellulose.  The additional substance may be sodium, potassium, or ammonium phosphate, acetate, tartrate, citrate, lactate, sulphate, thiosulphate, and sulphite, or barium, strontium, calcium, magnesium, or zinc acetate, citrate, tartrate, and lactate, or sodium, potassium, or ammonium oxalate, and formate, or sodium and ammonium chloride, or ammonium bromide, iodide, nitrate, and perchlorate, or cane sugar, glucose, fructose, mannitol, and sorbitol.  Salts of soap forming acids, and tri-sodium and tri-potassium phosphates are excluded.  The nitrogenous base may be methyl, ethyl, propyl, iso-propyl, amyl, di-iso-amyl, or an ethanol-amine.  It may be ethylene, propylene, or trimethylene-diamine, or piperidine, piperazine, cyclohexylamine, or other poly-methylene amine.  Water soluble bases in which each carbon atom directly attached to nitrogen is directly attached to three other carbon atoms, aliphatic amines containing up to six carbon atoms, or dimaines in which the two nitrogen atoms are separated by up to four carbons may be used.  The treatment may be carried out at high temperatures and with high concentrations of organic bases. Yarns may be treated in hanks or while travelling. Treatment may be carried out at raised pressure.  For this treatment the threads may enter and leave a closed vessel containing saponifying liquid, through perforated end plates, and may be guided beneath the liquid by rollers.  The materials may be under stretching tension or may be allowed to shrink during treatment, or they may have been stretched or shrunk prior to the treatment.  Saponification may be sufficient to impart affinity for cotton dyes, to increase tenacity, or to produce regenerated cellulose materials.  Specifications 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 378,858, 417,220, 429,103, 435,806, 438,584, 438,585, 438,586, and 438,587 are referred to.

Abstract: 773,837. Moulding blocks of plastic material on wires. WESTERN ELECTRIC CO., Inc. July 1, 1955 [July 7, 1954], No. 19084/55. Class 87(2). Parallel wires 29, Fig. 1, which are advanced in steps from left to right, blocks 28 of plastic material being moulded upon them between dies 17, 20 (e.g. to form components of wire-spring multi-contact electromagnetic relays such as those described in Specification 731,486 [Group XXXVII], are kept in their properly-spacedapart position by two guides 30, 31, supported by a vertically-movable knockout plate 34. The guide 30 is disposed on the wire input side of the dies. The guide 31 is disposed on the wire output side of the dies and is so constructed as to allow the moulded-on blocks to pass therethrough. This special construction of guide is shown in Fig. 6 (side sectional elevation). The guide comprises a base plate 80 and a top plate 87, both having slots 93, 100 between which the wires pass and cam surfaces 94, 103. As the wires with their blocks enter the guide from the left the blocks (which, of course, cannot pass through the slots with the wires) ride up the cam surface 94 (to the raised position shown in full lines) and then drop onto the base plate 80 (broken line position) : if they do not drop they are forced down by the cam surface 103. Fig. 4 is an end-on view of the guide, which is shown as a dual one having a central gap G through which passes the sprue and runners attached to a double line of the (injection-moulded) blocks. The sprue and runners are trimmed from the blocks by a punch and die 47, 48. Material is fed to the dies from an injection chamber 24 by a plunger 25. The upper die 17 is supported by a stationary platen 16 and the lower die 20 by a vertically-movable ram-operated composite platen 18, 19. When after moulding, the platen descends, downward movement of knockout plate 34 is arrested by stationary pins 35 and as die 20 drops (a) the wire guides 30, 31 hold the wires up and (b) knockout pins 39 eject the blocks from the lower die. The wires are then pulled along by a one-step pneumaticallyoperated pawl 41 which engages behind the blocks. Specification 747,370 also is referred to.
