Patent GB-766360-A (GB)
Title: Improvements in or relating to a method for insolubilising artificial filaments, threads, fibres and the like obtained by the spinning of solutions of proteins
Inventor: DAVIDSON WALTER LAMB
IPC: D01F4/00
Filed: 1954-05-05
Abstract: A process for insolubilizing bundles of coagulated protein filaments comprises subjecting the filaments to the action of a soluble alkali metal polymetaphosphate before subjecting them to a formaldehyde harding treatment, and thereafter impregnating the hardened filaments with an acidified solution of formaldehyde; the bundle is then stretched and, while stretched, is heat-dried until there is no further tendency to shrink, whereupon the bundle is further heated to such a temperature and for such a time as to effect insolubilization. The polymetaphosphate, which may, if desired, be incorporated in the spinning solution, has 4-70 or more phosphate units in the chain (up to molecular weights of the order of 2 million), and the treatment with this solution is best carried out at 50-90 DEG  C.  If desired, the hardening treatment may be carried out in two stages, in which case the first hardening solution, which may be of aluminium sulphate or sodium zirconyl sulphate, is used before the polymetaphosphate treatment, which is then followed, as before, by the formaldehyde hardening treatment. The acid formaldehyde solution is preferably salt-free and at pH 1-4.  The degree of stretch imparted to the filaments may be of 50-500 per cent, preferably 100-400 per cent, and the drying of the filaments is carried out at 0-160 DEG  C.; the subsequent insolubilization is accomplished at 120-180 DEG  C., preferably 140-180 DEG  C.  If desired, pigments may be incorporated in the spinning solution from which the filaments are obtained. Specifications 513,910, 533,952, 597,497, [all in Group IV], 605,830, 623,460 and 642,359 are referred to.

Abstract: 778,169. Washing-machines ; wringers; ironing-machines. HOOVER, Ltd. April 26, 1955 [May 7, 1954], No. 13402/54. Class 138 (2). [Also in Group XXIV] A washing machine including a washing liquid container 10 having a washing impeller 12 therein, and a driving motor 13 mounted under the container and connected to drive the impeller, is characterized by a flexible drive 39 connected to the motor 13 through a free-wheel or unidirectional clutch 35 and terminating adjacent the top of the container in a vertical shaft connected to a power-driven wringer or ironer, or an upwardly facing power take-off 40 for driving such a wringer 31 or ironer, and means 41 for reversing the motor at will. The impeller 12 is driven through a free-wheel or unidirectional clutch 17 so that rotation of the motor in one direction drives the impeller and not the wringer or ironer, whilst rotation in the other direction drives the wringer or ironer and not the impeller. Fig. 4 shows the clutch 17 in position for transmitting drive from the shaft 19 of the motor 13 through a driving member 18 and coupling member 22 to a clutch plate 25 keyed to a pulley 16 free to rotate on the shaft 19. The coupling member 22 is pivoted at 23 to the driving member 18 and is adapted to rotate so as to engage one of six dogs 27 on the clutch plate 25 when the shaft 19 is rotating in a clockwise direction as viewed in Fig. 4. A stop 30 on the driving member prevents engagement of the coupling member 22 with the dogs 27 when the shaft is rotating in the opposite direction. The pulley 16 is connected by a belt 15 to a pulley 14 on the impeller shaft. The clutch 35 is similar to the clutch 17 and is adapted to drive a free pulley 34 connected by a belt 36 to a pulley 37 on a shaft 38 connected to the flexible drive 39. A cooling fan 42 is keyed to the motor shaft and carries a flange 43 which transmits drive to a friction wheel 44 on the shaft of a pump 45 for emptying the container 10. The wringer may be pivoted through 90 degrees from the position shown in Fig. 1 so as to deliver clothes to instead of receiving them from the container 10. The wringer may have further positions projecting over the side of the machine. In a modification the emptying pump may serve as a counter-shaft to which the end of the flexible drive is attached so as to be driven by the same belt and pulleys whenever the wringer is being driven. Specification 701,977 is referred to.
