Title: Improvements relating to the manufacture of artificial threads, bands, films or the like
IPC: D01F2/08
Filed: 1929-03-12
Abstract: 307,758. I. G. Farbenindustrie Akt.- Ges. March 12, 1928, [Convention date]. Grant of Patent opposed. Apparatus for making filaments and films.- Spinning solutions to be used in the manufacture of artificial fibres, films, bands, &c.. are conveyed from the place of their manufacture to the place of coagulation solely by mechanical means, such as pumps, suitable heads, &c.. and without the use of compressed air. The removal of air or the prevention of the entry of air into the spinning solution may be assisted where possible by suitable control of the temperature of the liquid. In the apparatus shown, the cellulose is saturated with caustic soda lye in an immersion press, and subsequently pressed. The pressed alkali cellulose is then delivered to a disintegrator 2 and the comminuted material directly or after a maturing period is charged through a funnel 3 into the sulphiding drum 4. The finished xanthate falls from the open drum through the funnel' 5 into the dissolving vessel 6, where the xanthate is dissolved in dilute caustic soda lye and transformed into viscose. The discharge outlet of the dissolving vessel 6 is placed quite near to the pump 7, for instance a toothed wheel pump, which is fed with the viscose by gravity. The discharge pipe of the pump is connected directly with the filter press 8 but since the latter becomes less permeable in the course of filtration owing to the dirt, which it removes, the pump 7 is fitted with a bye-pass pipe 12 between the pressure side and the suction side and a pressure regulating valve 13, which maintains the pressure of the pump at constant level. From the filter press, the viscose passes through the pipe 14 into the spinning vessel 9, where the viscose is subjected to reduced pressure in order to remove emulsified or dissolved air and then, after the reduced pressure has been removed or while it is wholly or partly maintained, the viscose is forwarded by the pump 10, provided with a bye-pass pipe 15 and pressure regulator 17 anologous to those provided for the pump 7, to the spinning machine 11.

Filed: 1916-06-14
Abstract: 100,787. Ljusne-Woxna Aktiebolag. June 29, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Centrifugal governors.-In a centrifugal governor adapted for several speeds, each weight is connected to the muff 13 by two or more springs 1, 6 corresponding to the number of speeds, and each spring operates within a separate range of speed. The spring 1 is connected by a hook 2 to the weight and is screwed on to a cylinder 4 at the other end, so that by turning the cylinder, the tension of the spring is varied. The inner spring 6 is mounted on a sleeve 11 and its tension is adjusted by means of a nut 7 and screwed rod 8 connected to the muff. The nut 7 abuts against the sleeve 11 when the maximum speed corresponding to the spring 6 is reached. If the speed increases further, the spring 1 comes into action. The muff may be connected to the valve &c. to be controlled by links 14, 15, 16 comprising a movable pivot controlled by a hand-lever 17. When the lever 17 and links 15, 16 are moved from the stop position I to the position II, the valve is moved from the closed position B to the open position A, and the governor balls begin to rise, compressing the spring 6 and turning the link system about the movable pivot and gradually closing the valve. When the balls reach the highest position II at the minimum speed of the machine, the link system is in the position II<b> and the valve is closed. If a greater speed is to be used, the lever 17 is moved to position III and the links to position III<a>, in which the valve is open. As the speed increases, the balls rise above position II, tensioning the spring 1 and turning the link system about the movable pivot so as to close the valve gradually. When the balls reach the highest position III at the maximum speed of the machine, the valve is closed. The springs need not be placed one inside the other.
