Title: Process for producing electrolytic or galvano-plastic deposits
IPC: C25D1/20
Filed: 1933-08-08
Abstract: 428,440. Electrodeposition of metals. KELSEN SPECIAL SHEET HOLDING SOC. ANON., 33, Konigsring, Luxemburg. Aug. 8, 1933, No. 22217. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 9, 1934]. [Class 41] Detachable deposits are produced without the application to the cathode of a parting layer such as the thin layer of wax, silver iodide, metal sulphide, molybdenum oxides or arsenic hitherto employed ; this is accomplished in part by a suitable selection of the material of the cathode, but suitable adjustment of the working conditions such as temperature, acidity, currentdensity and circulation of the electrolyte are also necessary. Suitable materials for the cathode are those which are not readily corroded when immersed in the electrolyte without passage of current; examples of such are pure tin, pure chromium, alloys of tin or lead with antimony or arsenic, bismuth, lead, chromium steels containing tungsten and vanadium. Cathodes of the alloys known under the Registered Trade Marks " Silumin " and " Duralumin " may be used in sulphate solutions but not in chloride solutions. An alloy of 80 per cent tin and 20 per cent lead may be used as cathode for iron deposits. In an example a detachable deposit of iron is produced on a highly polished cathode of nickelchromium steel at a bath temperature of 76-90‹ C., initial current density at least 1 and preferably 5 amps. per sq. dcm. and pH greater than 3À0.

[Class 95] [Also in Group XVII] A method of wrapping articles, in an automatic machine, includes the step of applying solvent to cellulose derivative wrapping material by directing the solvent in the form of a fine spray to the desired portions of the wrapping material in such manner that the particles of the solvent are made very minute and are spread uniformly over the area. Apparatus described, for carrying out the above method,. comprises a conveyer 12 with pushers 13 which remove articles from a magazine 14 and move them into engagement with a severed web of cellulose derivative wrapping material from the reel 15. Portions of this web are. folded to produce side folds 18, on to each of which is sprayed a stripe 25 of solvent, transverse to the the direction of movement of the blank, by the spray guns 24 which are moved bodily through an arc, in timed relationship with the conveyer 12. Folders 22 then fold the portions 23 into overlapping engagement with the folds 18. In continued movement upwardly of the blank, the side flaps 30 are turned upwardly by folders 26, and receive horizontal stripes 28 of solvent from fixed spray guns 27. Further movement of the packet causes the side flaps 30 to be brought into overlapping engagement with the flaps 23, by means of the folders 29, and the open end of the wrapper is thereafter partly closed by tucking mechanism 31, and finally closed as the wrapped articles move into the stacker 32. Opposed to each fixed spray gun 27 is a container 35 with a hole 36 to receive sprayed solvent when no wrapper blank is passing. Solvent may be supplied to each spray gun from the tank 33, or the movable guns 24 may be supplied from the solvent accumulated in the containers 35. The fixed guns 27 are preferably operated continuously, but the movable guns 24 may be operated, by the cam 47, only when a blank is passing. Various forms of spray nozzles are described.

In the moulding of preferably non-circular section e.g. hexagonal, octagonal or elliptical, tubular objects from glass fibre reinforced polyester resin e.g. road lighting columns, sign posts, signal posts or beacons, the glass fibre reinforcement 19 is applied as one or more mattings or layers adjacent the interior surface of a vertical mould 11 which is provided with external steam or electrical heating coils 20 and to the lower end 11a of which is connected an inflatable tube 12 e.g. of rubber, and into which lower end e.g. via an inlet 18, a synthetic resin is admitted whereby, with a pressure difference created between the inflatable tube 12 and the interior of the mould 11, the inflatable tube 12 is caused to progressively inflate into the interior of the mould 11 by feeding the pinched end thereof through rolls 25 into the mould, to press the resin upwardly into the reinforcement. The pressure difference is created by a vacuum connection 15 into the upper end of the mould 11 or, alternatively or in addition thereto, pressure may be applied to the interior of the inflatable tube 12 inside the mould, via a casing 16 enclosing the lower part of the mould and the rolls 25. The resin may be admitted to the interior of the mould before, during or after the pressure difference is applied, either by means of the vacuum in the mould, and/or it may be pumped in. Preferably the pressure difference is maintained until the resin has hardened or cured, which may be effected by the heating coils 20. Preferably a thin tubular protective sleeve 21 e.g. of p.v.c., is inserted between the inflatable tube 12 and the mould and is connected at its other end on a tube 22 to the vacuum connection 15; a hole 23 in the tube 22 balances the pressure on both sides of the sleeve 21 and connects the interior of the mould to the vacuum connection 15. The sleeve may be drawn through and secured in the mould 11 after the reinforcement has been placed in the mould or, alternatively, the reinforcement may be applied about the sleeve 21 supported on a temporary mandrel which is withdrawn after the sleeve 21 has been secured at its upper end to the tube 22. Longitudinally extending metal reinforcing bars 24 may be located in the mould e.g. between two layers of glass fibre. The mould 11 is preferably provided with an overflow 26 at its uppermost end to receive excess resin.
