Title: Apparatus for the automatic changing of silver cans in machines for preparing fibres for spinning
IPC: B65H67/04
Filed: 1962-01-31
Abstract: 937,518. Coiling sliver. ZINSER TEXTILMASCHINEN G.m.b.H. Jan. 31, 1962 [Feb. 4, 1961], No. 3585/62. Addition to 937,517. Class 120 (3). In a sliver-can changing apparatus according to the parent Specification, the movements of the full deposit and reserve cans out of and into the working position are effected by two transport levers which are pivotably mounted in one or two segments movable along an arcuate path, the axis of pivoting allowing the levers to move between vertical and horizontal positions. As shown, a reversible motor 5 drives, through gears 7, a segment 3 from a position 3<SP>1</SP> to a forward position 3<SP>11</SP> so that a lever 10 moves a full can 1 to a position 1<SP>1</SP> on a conveyer 41 or 42 which is then advanced sufficient distance to permit reception of the next full can. During the return of segment 3 to its initial position, lever 10 is pivoted into vertical position by a cam or electromagnetic device. Simultaneously, with such return, a reversible motor 6, through gears 8, moves a segment 4 from rest position 4<SP>1</SP> to position 4<SP>11</SP> so that a lever 9 moves the empty reserve can 2 from waiting to working position, and is then also pivoted into vertical position during its return. Movement of the empty can releases a contact 16 and thereby causes advance of conveyer 31, 32 or 33 to bring another empty can into the waiting position, as permitted by operation of another contact by lever 9 reaching the vertical position, Fig. 6 (not shown). Movement of the segments may be effected by friction wheels (not shown). Conveyer 41 may be replaced by a circular conveyer (not shown), the can being positioned by grippers controlled from contact 16, or by an overhead magazine (not shown) from which empty reserve cans are released to slide into position. The transport of the cans may be effected by only one segment on which both transport levers are mounted.

Abstract: 371,968. Lifting-jacks. REID & SIGRIST, Ltd. and REID, G. H., Canbury Park Road, Kingston-on- Thames. Feb. 5, 1931, No. 3726. [Class 78 (iii).] Mechanism, particularly adapted for lifting purposes, comprises an arm 19 supported on a pin 20 'by a pair of arms 22, pivoted at 25, on bent angle irons spaced widely apart at the outer ends, where they are supported on a pair of rollers 16, the other end of the base member 12 formed by such angle irons being supported by a roller 18. A pin 28 on the arm 19 engages a slot 27 in the base member and is connected to a pair of chains 40, which pass round sprockets 36 on levers 30 and are secured to sprockets 42. The levers 30 are pivoted to the base member on pins 32 and normally engage the pin 20. In order to lift a load, e.g. the tail portion of an aircraft, on the end 50 of the arm 19, a handle 48, mounted on a shaft 46 connected to the spindle 43 of the sprockets 42 by worm gearing, is rotated so that the chains 40 draw the pin 28 along the slot 27 and raise the arm 19. The initial movement of the arm 19 is assisted by the levers 30 which are rotated in an anticlockwise direction and raise the pin 20, but after a predetermined lift of the arm 19 these levers become inoperative. The chains 40 are connected to the pin 28 by a pair of spring or gravity-controlled members 38 provided with pawls 38a which engage racks 52 when the chains 40 break, to prevent the arm 19 falling. The end 50 of the arm 19 may be provided with a detachable member capable of readily engaging a particular load. When it is desired to maintain the angular position of a loadengaging member substantially constant during lifting, e.g. when placing heavy bombs in holders at the underside of the fuselage of an aircraft, an arm is pivoted at one end to the arms 22, in such a position as to maintain substantially vertical a support for, or integral with, the load-engaging member, the said support being pivoted to the other end of the said arm and; to the end 50 of the arm 19. The mechanism may be moved as a whole on the) rollers 16, 18 by a handle 49, but the other traversing means such as endless tracks may be provided on the base member 12.

Patent GB-438023-A (GB)
Title: Improvements in processes for the manufacture of alloy steels and irons
IPC: C21C7/00
Filed: 1934-02-06
Abstract: Alloy steels and irons with low carbon content and containing a high content of alloying metals such as one or more of the metals chromium, nickel, copper, tungsten, titanium, vanadium, and molybdenum, are made by melting iron or steel in an electric arc furnace having carbon electrodes, removing all but a thin layer of the slag, charging upon the remainder of the slag a mixture of a reducing agent such as ferrosilicon and an excess of a reducible ore of the alloying metal or metals in an amount sufficient to provide a stiff thick slag, and then charging at a point remote from the electrodes scrap metal having a high content of the alloying metal or metals, preferably scrap having approximately the same composition as the steel or iron alloy which is required as the final product.  The amount of scrap added may be up to about 50 per cent by weight of the final tapped product. Preferably the scrap and the mixture of ore and reducing agent are divided into batches, a batch of ore and reducing agent being followed by a batch of scrap and all but a thin layer of the resulting slag being removed before the addition of the next batch of ore and reducing agent.  When the last batch of scrap has been incorporated in the bath the slag is removed and a finishing slag, e.g. a slag of burnt lime, fluorspar, and ferro-silicon, is added. In order to prevent the absorption of hydrogen produced by the decomposition of moisture the furnace may be vented or a reducing agent may be employed which will dissociate and combine with any hydrogen present.  Calcium silicide, i.e. an alloy containing 20-35 per cent of calcium, 50-70 per cent of silicon, and the balance mainly iron, may be used but preferably a mixture of this substance and ferro-silicon is employed.  The use of calcium silicide is also stated to prevent contamination of the metal by phosphorus which is present in the slag.  Alternatively, to prevent hydrogen absorption, sodium chloride, calcium chloride, potassium chloride, calcium hypochlorite, or metallic calcium or sodium may be added to the bath or the slag.  The preferred substance is calcium hypochlorite, this substance being mixed with the ore and reducing agent.  A mixture of calcium hypochlorite and the reducible ore is also added to the bath prior to the addition of each batch of the mixture of reducible ore, reducing agent, and calcium hypochlorite.  If desired, calcium hypochlorite may also be added during the finishing treatment.  The production of an iron-chromium alloy having a carbon content of less than 0,1 per cent and a chromium content of 17-18 per cent is described, the alloy scrap added containing 0,12 per cent of carbon and 18 per cent of chromium.  Prior to tapping, manganese, ferromanganese, titanium, &c. may be added to the bath as deoxidants or alloying ingredients.  The Provisional Specifications describe the methods of preventing hydrogen absorption set out above applied generally to any process of manufacturing alloy irons or steels by direct reduction.
