Title: Improvements in stop motion and yarn tensioning arrangements for textile twisting and winding machines
IPC: B65H63/02
Filed: 1945-10-01
Abstract: 621,201. Winding yarns. DEHN, F. B. (U.S. Textile Machine Co.). Oct. 1, 1945, No. 25445. [Class 120 (ii)] A textile machine, such as an "up-twister," having winding units comprising a yarn package: driven by a friction drum and yarn breakage detector: means adapted to move an element between the drum and the package to discontinue the drive on yarn breakage, has a manually, actuated member arranged to move and hold the yarn breakage detector means in inoperative position, so as to prevent insertion of the element between the drum and the package. The yam Y normally supports a detector wire 42, Fig. 12, connected to bell-crank levers 32, 33 (33 not shown) between which a plate 39 is supported. Yarn failure allows the wire 42 to swing back causing insertion of the plate 39 between the package 22 and the drum 23. A rod 43, Figs. 6 and 12, is brought to bear on the wire 42 by means of a manually rotatable crank 53, Fig. 6, so as to support the wire when the yarn is slack. Rotation of the crank 53 effects a simultaneous support of the detector wires of each winding unit on each side of the machine. The yarn Y is tensioned by passing through an adjustable eyelet 24, over a rod 63, secured at each end in an adjustable plate 55 pivoted at 45, and under an eyelet 42a of the wire 42.

Patent GB-356922-A (GB)
Title: Apparatus for relaying the indications of measuring instruments, more particularly for giving larger scale indications by light-band for long distance observation
IPC: G01R1/08
Filed: 1930-08-26
Abstract: 356,922. Mechanical relay devices. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Aug. 26, 1930, No. 25501. Convention date, April 7. [Class 118 (ii).] In apparatus for relaying or indicating on a large scale the deflection of a measuring instrument pointer, in which a dropping bracket periodically holds the pointer the throw of which is displayed on a larger motor adjusted indicator, a contact device for switching in the latter is rotated by the motor to follow the movements of the pointer and is actuated by the dropping bracket according to the deflection of the pointer. The pointer a of the measuring instrument b is adapted to move between plates c1, c2 and a dropping bracket o which periodically, for example by means of clockwork actuating a contact s of an electromagnet p, descends to force the pointer a, if deflected, against plate c1 or c2, thereby closing contacts f1, g1 or f2, g2 causing a motor h to rotate. Operation. Normally, with the pointer a undeflected, Fig. 1, contacts f1, g1, f2, g2 are not closed on descent of the bracket o. Should the pointer be thrown, Fig. 2 (when the bracket o is released), contacts f1, g1 will be closed on the next descent of bracket o. The motor h is thereby rotated, and through gearing i drives a disc e, carrying the discs c1, c2 on springs d1, d2, until the gap between said discs comes underneath the pointer a, when the circuit of the motor is broken. The motor also drives, through gearing k, a drum on which is wound an obscuring band l, the length of a light strip, consisting of an illuminated channel m, uncovered by the band l being proportional to the throw of the pointer a. This indication may be read off on a scale n consisting of illuminated slots. For all movements of the pointer a the motor h will be rotated in an appropriate direction to move the discs c1, c2 to the position in which no further circuit for the motor is made, the uncovered light strip in all cases representing the deflection of the pointer. The contacts s are maintained closed for a time sufficient to enable the motor h to move the disc e until the pointer a is between the plates c1, c2. Other means of transmitting the pointer deflection may be used. Thus, the member regulating the resistance in the circuit of a remote measuring instrument may be geared to the motor shaft, or a current impulse transmitter may be geared with it which sends impulses at a rate proportional to the deflection. Also means may be connected to the disc e for recording the deflection of the pointer a.

Title: Process for spinning viscose
IPC: C22B1/10
Filed: 1934-09-10
Abstract: Viscose is used for spinning purposes which has a degree of ripeness corresponding to a salt point of 0,1-0,2 or lower. Spinning may be initiated or completed in a spinning funnel using water or a very dilute electrolyte solution as coagulant, and the ripening process may be accelerated by an increase in temperature. The silk produced is stated to be similar in "feel" dyeing capacity, cross-section, and tensile strength to copper silk.  In an example, viscose containing 7,5 per cent of cellulose is stored for a further 3 days at 20 DEG C. after it has attained a salt point of 0.1.  It is then spun at a pressure of 8,5 atmospheres through a head with 92 spinning holes each about 0,8 mm. in diameter) into a slow stream of water in a spinning funnel, whence it is passed over a guide to a trough through which a solution containing 3,5 per cent of sulphuric acid and 6 per cent of sodium sulphate is flowing, and is finally reeled at \ba1/2\be to 1 metre from the trough.  The speed of draft is 80 m. per minute and the spun material has a titre of 140 deniers.  In a second example, viscose composed and ripened as in the first example is coagulated at 16 DEG  C. in a spinning funnel with an aqueous solution containing 0,5 per cent sodium sulphate and 0,025 per cent sulphuric acid.  The thread is then passed through a bath containing 10 per cent of sulphuric acid and 3 per cent of sodium sulphate.  The conditions are arranged to produce an individual titre of 1,3.  The dried product has a tensile strength of 203 grams/100 deniers and an extension of 14,6 per cent.

Abstract: 1395535 Fuel injection pumps MASCHINENFABRIK AUGSBURG-NURNBERG AG 2 June 1972 [4 June 1971] 25987/72 Headings F1A and F1K In a fuel injection pump wherein the delivery is adjusted by a rack 4 meshing with a pinion 3, the rack 4 being displaceable by control linkage connected to a rod 5 to effect relative rotation between a pumping piston 2 and its cylinder, the fuel delivery can be reduced independently of the fuel control linkage. The independent reduction of the delivery is initiated by an engine speed or temperature responsive control circuit 32 operable to control a valve 31. When the valve is opened fluid from a source 21 is admitted to a cylinder space 18 thereby to displace a piston 17. The piston 17 acts through a rod 12 and a spring 14 to move a further rack 11 in a direction which drives the pinion 3 towards its zero delivery position. Movement of the pinion 3 is permitted, even if the control linkage is jammed, by compression of a spring 6 disposed between the rack 4 and the rod 5. The valve 31 may control the supply of fluid to further cylinders 28-30 for simultaneously reducing the delivery from additional pumping cylinders. A bolt 33 may be screwed into the rack 11 to prevent the latter from moving to a position corresponding to maximum delivery.

The blank 2 is mounted on a mandrel 1, Fig. 7, which is connected to a hydraulic ram 41 working within a second ram 19, the hydraulic cylinder 20 being mounted so as to be partially rotated during the feeding of the mandrel. The hydraulic feed cylinder is mounted in bearings on a slide 21 which is initially positioned by a ram 25 operated by elastic fluid to absorb shock. The slide carries a shaft 35 geared at 38, 37 to the feed cylinder and splined within a skew-wheel 34 intermittently rotated through ratchet mechanism 27, 28, Fig. 5, actuated by the roll driving shaft. The pawl may be loaded &c. as at 32 to remain inoperative except when thrown into engagement by a hydraulic cylinder 31. Power to operate the feed rams is supplied through a swivel socket 39 mounted on the end of the hvdraulic cylinder. The fluid pressure acting behind the rams 44, 19 first moves the mandrel and its guide 18 as one unit, till the guide is arrested by the shoulder 18<a> contacting with the cylinder bearing 23 after which the mandrel proceeds alone to permit the end of the blank to be rolled. The mandrel passes through a universal socket 16<a> and is connected to a block 17 on the ram 41 so that it may be readily disconnected and withdrawn rearwardly sideways when renewal or exchange of the mandrel is required. A pair of cylinders 26 mav be used instead of a single one and the shaft 35 may be axially stationary, in which case the driving gear for the hydraulic feed cylinder is splined thereon. One of the Provisional Specifications describes the use of a spring cushioning device for absorbing shock resulting from the action of the dies on the blank.
