Title: Improvements in thread storing, thread advancing reels
IPC: D01D10/04
Filed: 1946-01-16
Abstract: <PICT:0608781/IV(a)/1> During the continuous spinning of artificial filaments, yarns are laid on a liquid-treatment reel by a quickly rotating whirler tube 11 and after being advanced to the other end of the reel by pairs of rocking bars (see Group IX), are removed from the reel by another whirler tube 12.  The reel may be of sufficient length to allow all the treatment operations required in the production of viscose or cuprammonium rayon yarn to be effected upon it and may be used for tows of 60,000 denier or more.  Treatment liquids are applied at or near the top of the reel in zones spaced apart to prevent commingling.  Scraper blades 150, situated beneath and close to the yarn on the reel, make contact with drops of liquid formed on the bottom of the reel to effect their removal into liquid collecting troughs 10.  Specifications 2643/57, [Class 2], 3831/11, [Class 2 (ii)], 413,413 and 413,414, [Group IX], are referred to.

[Class 38 (v).] A set of switches for controlling a number of circuits are arranged so that only one circuit can be closed at a time. In the form shown, three circuits are arranged to be controlled by keys 1, 2, 3 which actuate contact mechanism not shown. On depression of a key, its lower end enters between a row of balls 10 in a trough 9 displacing them against the action of springs 11, 12 and thus preventing the depression of any other key. The operated key is retained in its depressed position against the action of its return spring 5 by the engagement of a notch 15 with the edge of a common locking bar 13 pivoted at 19 and controlled by a spring 14. A release key 4 which does not control any contact is provided with a smooth flange 18 which, on depression, moves the locking bar without being locked itself, and releases the operated key.

[Class 38 (v)] In a multipolar automatic circuitbreaker composed of single - pole switches, each operated by a pair of toggle levers k, l, the separate switches are provided with levers g which are positively connected together and embrace, by arms h, i, the pivot pin e or other part moving positively with the toggle levers, so that when one of the switches is tripped, the embraced part e strikes against the arm i of the corresponding lever g, whereby all the levers g are moved and the arms h trip the toggles of the remaining switches. In the arrangement shown, two switches a, b are provided, with operating levers d connected together by a cross-bar t carrying a handle v. On rotating the handle in a clockwise direction, a lever r in each switch is rotated in the opposite direction about a pivot s, and the extended toggle levers k, l, which are pivoted respectively to the lever r and to the'contact lever m, move the contact lever to the closed position against the action of a spring f. On overload in either switch, an armature w moves upwards and breaks the toggle, whereupon the switch opens, and towards the end of the opening movement, the pivot pin e of the toggle strikes the arm i of the lever g, and rotates this and thereby the corresponding lever in the other switch, the two levers being connected together by an insulating tube p. The arm h of the second lever g breaks the toggle in the second switch, which thereupon opens and allows the handle v to return to the open position under the action of a spring q.

The plates 27 of adjacent elements 23 overlap to reduce friction when the craft is under way. The gaps formed between adjacent elements 23 when passing round the bow and stern of the hull 9 is maintained closed to prevent ingress of rubbish by plates projecting from one element underlapping the buoyant sections of the adjacent element 23. A rudder 21 for steering and screw propellers (not shown) for additional propulsion are also provided.

The metallic components (electrode grids and electrical connections made of lead antimony alloy) and the inactive materials (ebonite containers, sealing material and partitions made of wood, fibre glass or synthetic resin) Which, together with paste or active material (lead oxide and lead sulphate), form the main constituents of scrap storage batteries are separated from one another by treating fragments of the batteries with an aqueous suspension of separated paste, the suspension having a density intermediate that of the metallic components and that of the inactive materials, and then separating the inactive materials which float in the suspension from the metallic components which sinks in it. The fragments are preferably free of paste which, for example, may be separated in a dry powdery condition in a process which includes the crushing of the batteries into fragments. In the separating plant shown, fragments of batteries (arrow A) and an aqueous suspension of paste (from a tank 14) are fed to the inlet 6 of a separator 1 comprising a revolving drum in which a spiral 2 conveys the metallic components towards an outlet 3 through which they are discharged by means of paddles 4 via a chute 5. The inactive materials floating on the suspension are removed therewith via the inlet end of the separator 1 and conveyed to an inclined, perforated revolving drum 7 from which the suspension is discharged via a funnel 18 into the tank 14 and the inactive materials are discharged (arrow D) after being washed with water pumped from a tank 13 via perforated pipes 10. The metallic components fall from the chute 5 on to a screen 11 and after being washed with water recycled from tank 13 and with fresh water (arrow B) are discharged (arrow C). Wash water from screen 11 and drum 7 is directed to a settling tank 11, the overflow being led to tank 13 and the underflow, i.e. thickened paste suspension, being pumped into tank 14. Excess paste may be removed (arrow E) by filtering. The drum 1 instead of having a conveyor screw 2 may be inclined to the horizontal or may be furnished internally along its whole length with paddles to lift the metallic components and drop them on to a conveyer. The drum 7 may be replaced by screens.
