Title: Process of manufacture of artificial silk and of artificial threads or filaments andapparatus therefor
IPC: D01F2/30
Filed: 1925-01-24
Abstract: 238,842. Soc. pour la Fabrication de la Soie Rhodiaseta. Aug. 22, 1924, [Convention date]. Apparatus for making filaments; cellulose solutions, processes for making filaments from. - In the dry spinning of artificial silk &c. from solutions of cellulose esters, ethers or other cellulose derivatives, in particular cellulose acetate solutions, the gaseous medium introduced into the cells is already richly laden with the vapours of the solvent whereby filaments of a circular or almost circular cross section are obtained. Bv such an adjustment, the formation of an initial hard layer on the exterior of the filaments is prevented, so permitting a free passage of solvent from the interior and facilitating the drying process; in addition the solvents can be readily recovered by direct condensation. Conveniently, spinning takes place in a closed system constituted by the cell a, condenser g, propelling-device e, and re-heater j; the spinning solution is supplied to the spinning-head b through a pipe c jacketed for heating, and the filaments leave the cell through a small opening d; a branch n connected to aspirating and solventrecovery apparatus enables gas to be withdrawn so as to create within the cell a depression sufficient to prevent the escape of solvent vapours through the outlet d. Alternatively, a system employing natural circulation may be used, the evaporative gases being supplied to the upper part of the cells and after being laden with solvent, falling by gravity. To obviate explosions, it is convenient to employ an inert gas as the medium in circulation. The apparatus may be otherwise arranged and constructed as described in Specification 233,384. The Specification as open to inspection under Sect. 91 (3) (a) refers to the manufacture of artificial silk of cross-sections other than circular, by suitably varying the proportion of solvent vapours in the gaseous medium introduced into the cells. This subject-matter does not appear in the Specification as accepted.

Jan. 25, 1932, Nos. 2268 and 13201. [Class 98 (i).] In a film-pack casing of the type comprising two shells formed as plates with marginal flanges, the end flange of one shell being removed to permit of endwise sliding assembly, the marginal flanges are provided with means for interfitting engagement throughout their length to act as guides during assembly, to prevent separation of the assembled shells and to form a light trap. The engaging means may be in the form of grooves, and co-operating parts may be formed in them to provide a catch. In the form shown, the casing consists of two shells 10, 11 having grooves 14 in the side flanges, a break being formed in the grooves at 35 to provide a catch for retaining the shells in assembled position. The front shell 10 has the usual exposure window and at the upper end the side and end flanges are cut away to about one half the thickness, the cut portions being turned inwards as at 18. A cap of metal 21 fits over the reduced end flanges and projects into the case, providing a short internal wall over which.a V-shaped strip of cardboard 32 is fitted, the outer end of which is faced with plush to form a light trap with a similar piece of plush on the rear wall of the shell 11. The pressure plate comprises a flat sheet of metal having a rib formed on the rear surface to engage spring tongues 27, Fig. 3, pressed out of a plate 24. A second set of tongues 28 engage the.lower end of the pressure plate. The plate 24 has a rounded edge 29 at the bottom to facilitate the passage of the films from the front to the rear compartment, and two wings 30 to space it from the back wall of the case, the upper end being in engagement with the short internal wall. The two parts of the casing may be slid apart a short distance to enable the films to be completely withdrawn from the case. In another form the catch is constituted by a pin-and-hole connection. Alternatively, tongues formed on the outer shell may be turned inwards over the flaps 18 to retain the shells in assembled position. Specification 367,095 is referred to.
