Title: Improvements in or relating to the manufacture of artificial staple fibres
IPC: D01D5/26
Filed: 1933-11-01
Abstract: <PICT:0428368/IV/1> <PICT:0428368/IV/2> <PICT:0428368/IV/3> Artificial staple fibres are produced by interrupting the solution fed to the extrusion nozzle, increased pressure being applied to the interrupted solution intermittently, so that the solution is extruded as separated staple fibres.  Interruption of the solution is preferably effected by a valve.  The spinning solution enters passages 9 and passes to a series of holes 8 covered by a sleeve 10. The latter is reciprocated by a cam actuated lever 11, so allowing the solution to flow intermittently to the spinneret 12.  A non-return valve 14 communicating with the atmosphere is fitted in the piston 13, so as to prevent the coagulating material from being sucked back through the spinneret. Fig. 3 shows the whole apparatus, the nozzle being disposed within the constraining device 18, described in Specification 394,049, to which coagulating liquid is fed from the trough 23.  The pump 20 forces the spinning solution through the filter 22 and the nozzle to the centrifugal pot 24.  Cams 19 actuate the levers 11, 16 of the nozzle.  In a modification, Fig. 5, the frame 32 carrying the nozzle 27, filter 22, cam drive 19 &c. is reciprocated vertically by the crank 33.  Coagulating liquid from troughs 23 overflows into contact with the staple fibres as they issue from the nozzle 27; the staple fibres are fed by rollers 28 on to the travelling perforated rubber band 29, carried on rollers 30.

Filed: 1932-10-29
Abstract: 394,220. Knotting-apparatus. COOK & CO. MANCHESTER, Ltd. and COOK, N., 18, Exchange Street, Manchester. Oct. 29, 1932, No. 30367. [Class 112.] Hand apparatus for tying weavers' knots is provided with two slots on each side, each slot having a clipping or holding member working in conjunction with the knotting bill, so that the strands are held and released during the knotting operation, avoiding the necessity for the operator to hold the strands. The knotter is secured to the left hand, the left thumb being placed on the trigger 11 and the two strands to be knotted being laid across. The back strand is passed into the slot 50, across the device behind the arm 35 and down the slots 34, 32 of the slider 28 and fixed side arm 30 respectively. The front strand is passed into the slot 47 and into the slots 33, 31 in the slider and fixed side respectively. As it is pulled down into these two slots it is carried over the hood 39 and thus passes under the hood and across the knotting bill spindle just behind the bill. In passing from this position to the slots 33, 31 it is guided into the slot of the cutter 41 at the edge of the swinging arm 36. When the two strands are placed in this position they will both lie at the bottom of the slots and also will lie across the knotting bill spindle uncrossed, the front strand lying nearer to the knotting bill than the back strand. When the trigger is depressed, the knotting bill rotates in a counterclockwise direction and simultaneously the bellcrank lever arm 26 engaging the fork 27 moves the slider forward. At the same time the lever 53 is lifted and presses the pin 51 upward moving the slider 45 on the inside of the swing- ing arm and pressing the spring 49 against the spring 48 to nip the strand lying in the slot 50. The other strand in the slot 47 is nipped between the projecting portion 46 of the slider and the front face of the swinging arm. As the tying is completed, continued downward movement of the trigger brings the horn 23 into co-operation with'the downwardly extending part 52 of the slider 45, so forcing the swinging arm outwardly to draw the knot off the bill and actuate the cutter.

A device for maintaining pressure in an accumulator A. C. between two predetermined limits, the accumulator being supplied through a non-return valve S and having an outlet 7, comprises two slide valves T1, T2 subjected to accumulator pressure and loaded by springs R1, R2 in chambers E1, E2. The spring R1 is calibrated to balance the lower pressure and the spring R2 the upper pressure. The valve T1 controls the connection of the supply A to a drain passage Z while the valve T2 controls the connection of a passage H from the chamber E1 to drain passage D or a passage L which is in constant communication with the supply A. With the valves T1, T2 in the position shown, the supply is feeding the accumulator. When the accumulator pressure reaches the upper limit, the valve T2 is lowered to connect the chamber E1 to drain whereupon the valve T1 moves downward to connect the supply A to drain. As soon as the accumulator pressure falls, the valve T2 moves upwards but since the supply is connected to drain, the pressure in chamber E1 remains at drain pressure and the valve T1 does not move upwards under the action of spring R1 until the accumulator pressure has fallen to the lower limit, after which the supply then feeds the accumulator.

Abstract: 709,901. Code telegraphy. STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE, OBERMAN, R. M. M., and SNIJDERS, A. Nov. 29, 1949, No. 30638/49. Class 40 (3) A telegraph repeater includes an impulse generator (B2a and B2b) which, on receiving a start signal generates equally spaced sampiing pulses at approximately the middle of received signal elements, a start and stop device (B1a and B1b) wh'ch maintains the generator in operation for the whole duration of a received signal, and a transmitting device (B3a and B3b) which transmits signal elements whose times of occurrence and spacing corresponds to those of the sampling pulses, and means including a resistance capacity time constant circuit are provided in the impulse generator for preventing the generation of a second train of sampling pulses until the stop element of a preceding signal as re-transmitted shall have endured for at least a fixed minimum time. This latter feature prevents messages being run together owing to distortion. The various devices as shown are pairs of valves connected together as multivibrators. The condenser C5 in conjunction with resistance R20 holds the grid of valve B2a negative for 10 m. sec. and thereby serves to stop the generation of sampling pulses for a desired minimum time. The start-stop device is arranged to operate after a desired time interval by time constant circuit C1, R6, and adjustable resistance R5. A relay A in the start-stop device through its contact "a," maintains the impulse generator in operation irrespectively of the sign of the received signal elements. This relay is provided with a short circuited winding rendering it slow to respond to start signals to avoid clicks affecting the messages. Relay O receives the messages, and relay Z retransm:ts them.
