Patent GB-596999-A (GB)
Title: A new or improved device for checking and cleaning threads from a spinning or twisting operation
IPC: B65H63/06
Filed: 1945-07-19
Abstract: 596,999. Thread-clearing apparatus. DOLL, J. E. July 19, 1945, No. 18531. Convention date, April 7, 1944. [Class 120 (ii)] A device for checking and cleaning threads from a spinning or twisting operation, designed to stop slubs but to allow knots to pass, comprises a stopping member through or below which the thread to be checked passes, and a plate arranged obliquely in the path of travel of the thread in advance of the stopping member, the said plate having a slot of width slightly less than the anticipated minimum diameter of a knot and terminating in an open end disposed laterally of the stopping members. As shown in Figs. 1 and 2, a thread 1 passes through a slot 3 in a plate 4 arranged obliquely in front of the stopping member which is constituted by a slot cleaner 6 arranged at right angles to the thread 1. Knots slide up plate 4 and by-pass the stopping member, while slubs which are wider than slot 3 gain therein, and slubs narrower than slot 3 but wider than slot 5 are stopped by slot cleaner 6. Instead of a slot cleaner, the stopping member may comprise a feeler 7, Fig. 4, which when lifted by a suitably thick slub releases a spring-loaded flap 13 to trap the thread. In another embodiment, Fig. 7, the stopping member is arranged to pass slubs which exceed the critical width but which have a length less than a predetermined dimension d. A slub longer than d raises feeler 34 and causes finger 37 to depress arm 24 so as to close gap 21 between blades 23 and 27. Block 28 carrying blade 27, stop 26a, pivot 33 and finger 37 are all adjustable according to the critical dimensions of the slubs to be stopped or passed. It is possible for a soft slub of more than the allowable width to be forced through gap 21 without being stopped. This is guarded against by a modification, Fig. 8, in which the thread passes beneath two feelers 42, 47 spaced apart by the distance d, the simultaneous raising of both feelers or the excessive raising of feeler 47 alone, serving to release a spring-loaded flap 59 to trap the thread. Base piece 40, stop 44a, pivot 45 and finger 53 are all adjustable to vary the critical slub dimensions.. In a further modification, the flap 59 is arranged in advance of the feelers. Pig-tail or other guides 2, Figs. 1 and 4, may be provided with any of the embodiments. In order to prevent a long slub which has passed through slot 3 by being flattened, from passing through the stopping member, the thread may be turned through an acute angle around a guide, such as a cylindrical roller or a porcelain finger, arranged between plate 4 and the stopping member. In order to limit the sizes of knots which are passed, there may be arranged before or after the device a further cleaner, for example a slot cleaner, capable of stopping knots of a diameter greater than that which is acceptable.

Title: An apparatus for manufacturing metal grains, such as pellets, shot and the like
IPC: B22F9/08
Filed: 1945-07-20
Abstract: 605,953. Granulating metals. MORANE, R., and MARTINET, R. July 20, 1945, No. 18650. Convention date, Aug. 4, 1943. [Class 82(ii)] A machine for making metal grains, shot, &c., has a manually adjustable valve 2 and an automatic stop valve 9 between the melting pot 1 and a ladle 5 which has means to distribute the molten metal evenly over the bottom of one or more sieves 12. The valve 2 is adjusted to deliver faster than the sieves discharge so that the ladle tends to fill but it is carried by a vertically movable and counterbalanced support 6 so that, when full enough, it moves down and a trip 28 operates a switch 29, in circuit with a solenoid 8, to close the valve 9. When the level of metal in the ladle falls this rises again and reverses the switch 29 and opens the valve 9. Instead of an electric a pneumatic, hydraulic, &c. control may be used. The ladle has a calibrated nozzle 10 for each sieve 12 to keep a constant depth of metal therein. The sieves are rotated, at a speed sufficient to prevent the formation of double grains, by a motor 14, reducing gearing in a box 20 and a carrier 15. Each nozzle 10 delivers to a pivoted shoot 11 which may have heating means b, Fig. 3, and which is oscillated, to distribute the metal over the bottom of the sieve, by a cam thereon engaging a roller 30 connected to said shoot by a crank 30a &c. A spring hammer 22, pivoted at 24, is associated with each carrier 15 and is raised by projections 39 thereon to strike the sieve it carries thus preventing the holes in it from becoming clogged. The molten metal in the pot and ladle may be covered with charcoal to prevent oxidation.

INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) June 29, 1931, No. 18770. Convention date, June 28, 1930. [Class 38 (v).] In an earth-leakage protective system employing a neutral-point resistance and a series overcurrent or wattmeter relay, the setting of the relay is kept low by using an iron strip resistance of high positive temperaturecoefficient so that, with high neutral-point voltage, the current through the relay is lower than it otherwise would be. A suitable resistance is made in strip form of soft Siemens- Martin iron. To deal with momentary peak currents, the resistance may be connected in the secondary circuit of a transformer having a high voltage and its primary connected between the neutral point and earth. The secondary-may also serve to supply the voltage coil of the wattmeter relay.
