Title: Improvements in and relating to fluid filters and the like
IPC: B01D29/01
Filed: 1959-04-04
Abstract: 944,696. Moulding supports for filters. R. H. EATON-WILLIAMS, and D. A. G. MARSHALL. July 1, 1960 [April 4, 1959; June 15, 1959; Nov. 27, 1959], Nos. 7545/59, 20404/59 and 40489/59. Heading B5A. A fluid filter is produced by locating a cylindrical wad 33 of filter media, e.g. a felt of bonded polythene, or polyamide &c. fibres, between core members 22, 23 having cylindrical parts 29 and stems 30 and outer mould parts 20, 21 having flanges 28, with the ends of the felt projecting through the gaps 32 between the parts 29 and the flanges 28 into cavities 31 closed by end plates 24, 25. Polythene or polyamide &c. is then injected into the cavities and bonds to the ends of the felt to form support rings for the filter. The support rings may include metal or plastic reinforcement and a filler such as fibreglass. The co-operating parts of members 28, 29 and the surfaces of recesses 27 may be corrugated. In the embodiment of Figs. 1-3 (not shown), a substantially planar filter is provided with triangular &c. means for supporting metal reinforcing bars in an outer moulded support frame. One electrically conducting reinforcement in a moulded support frame may be connected to a high voltage source so that the filter may be used as an electrostatic charged-media unit. The filter support may alternatively be of polyvinyl chloride, polystyrene, polypropylene or of a polyester resin. The filter media may alternatively be of cellulose acetate, polyvinyl chloride, polystyrene or a polyester resin.

Abstract: 771,395. Induction heating. DEUTSCHE EDELSTAHLWERKE AKT.-GES. March 16, 1955 [March 29, 1954], No. 7700/55. Class 39(3) [Also in Group XII]  In a continuous induction-heated furnace, workpieces 1 are conveyed longitudinally through the heating coil 2 step-by-step on a conveyer system comprising stationary rails 6 on a frame 5, and movable rails 8 on a frame 7 given an upwards, forwards, downwards and backwards movement by an eccentric 9. During the backward movement the workpieces rest on the stationary rails. In a modification, Figs. 3 and 4 (not shown), the frame 5 is also oscillated by an eccentric, the two movements being co-ordinated to give continuous movement of the workpieces. Another modification, Fig. 5 (riot shown), has two induction furnaces arranged in sequence. The rail systems are made of non-magnetic, heat-resisting material and the eccentrics may be replaced by cams or by hydraulic or pneumatic actuating means. The conveyer system may be operated in reverse if necessary.

Rail joints.-The wear between rail ends and fishplates is taken up by packing-plates having portions of different thickness. The plates are placed between the fishplate 2, Figs. 1, 16, and the head 1 or flange 10 of the rail and have parts 17, 18 of unequal length or thickness for use in the different positions or with different sizes of rail or inverted. The plates 3 may taper from the centre to the ends, and one side 67, Fig. 21, may be thicker than the other side 68. The parts may be grooved or waved to receive lubricant or allow for swelling caused by punching the bolt holes. The outer edge 5, Fig. 17, of the plate may be upturned to receive the lubricant. The plate may comprise upper and lower parts 23, 25, Fig. 10, joined by a web 29. The web 29 may be narrower than the remainder, or the fishing-angles may have central openings. For use with oneway tracks ,the shims may have a one-way taper 65, 66, Fig. 20, and engage only the receiving rail.

Title: Method of and apparatus for treating molten metals
IPC: C22B9/10
Filed: 1965-02-26
Abstract: <PICT:1076456/C6-C7/1> Molten metal, particularly steel, is treated while flowing through a chamber by introducing the melt to be treated, e.g. from a ladle 1 provided with a stopper 27, through an inlet 17 into the chamber 10, dividing it into two portions one providing a marginal flow along the chamber wall and the other a central stream spaced from the marginal flow both towards the chamber outlet 18, introducing refining materials such as deoxidizing and degassing agents into the central stream prior to it reaching the outlet e.g. feeding magnesium wire 8 by rollers 7 through openings 9 on one side of the chamber and injecting a mixture of CCl4 and TiCl4 (to give a TiC addition to the melt) through a nozzle 26 on the other side from a container 6 by means of pressurized gas in steel container 23, to cause the melt to be atomized and thrown against the portion flowing along the chamber wall for admixture therewith, and withdrawing the mixed portions through the outlet 18. The dividing is preferably effected by a frustoconical body 14 placed in the upper section of the chamber and having passages 16 for the marginal flow and a bore 15 coaxial with the inlet 17 for the central stream.  The passages 16 may define a spiral path for imparting a twist to the melt. Below the main treatment chamber 10 a second chamber 11 may be provided interconnected therewith via the outlet 18 into which further alloying material may be introduced through an opening 28, e.g. granulated CaSi 19 fed in from a container 4 by a conveyer worm 5.  The lower portion of the chamber 11 may be restricted by a closure body 21 for accumulating the melt prior to discharge through outlet 24 which may be surrounded by a cylindrical body 34 immersed in the melt of the collecting ladle 2 for the protection thereof. Other halides may be used as the refining agent, e.g. NbCl5, introduced through the nozzle 26, and the CaSi fed through the conveyer worm 5 may additionally contain sodium borate and lime. Gases used in the treatment may include A, He or N2.
