Title: Improvements in or relating to the electroplating of metallic wire
IPC: C25D7/06
Filed: 1947-03-18
Abstract: 645,834. Electroplating coiled metallic material. KENMORE METALS CORPORATION. March 18, 1947, No. 7465. Convention date, March 13, 1946. [Class 41] [Also in Group XXII] A method of electro. plating a coil of metallic material comprises supporting the coil in the form of a helix and advancing it along a helical path by means of a driven roller, holding the helix against the roller by the application of pressure during advancement through one or more electro-plating baths, and determining and maintaining uniform the size of the turns of the helix fed to the driven roller, by means including grooved rollers driven in synchronism with the driven roller. As shown, wire 12 is fed at a high speed between grooved rollers 61, 62 and below an adjustable grooved roller 67 before passing in helical form over a roller 10 against which it is passed by an adjustable roller 15. The wire passes through several baths, such as rinsing baths and acid baths, before passing through an electroplating bath 33. Partitions between the baths are offset and tapered to facilitate passage of the coil from one bath to the other. The wire may be maintained in position in the bath 33 by rods 42, 43 and spacers 41. Two wires may be plated simultaneously, the wires being spaced apart and each wire having its own set of rollers for forming the helix. Steel wire may be plated first with copper and then with zinc, and the platings then annealed to form a brass-like coating on the wire. The wire can then be drawn down to a smaller size, for use, for example, in the formation of screens. A bronzelike plating may similarly be formed, tin being used instead of zinc. Specification 601,994 is referred to.

Title: Improvements in or relating to methods of preventing scaling of a hollow metal article during heating operations
IPC: C21D1/70
Filed: 1945-03-26
Abstract: A method of preventing scaling of a hollow metal article during heating operations comprises applying to the interior surface of the article while relatively cold and free from scale, an aqueous suspension of a frit having a fusion point below the temperature to which the article is to be heated, preliminarily heating the article to dry the frit coating and subsequently heating the article to fuse the frit so as to form a protective coating on the interior surface during the heating operation.  The invention is described as applied to the manufacture of a hollow poppet valve for aircraft engines.  An open-ended blank from which the valve is to be formed is given an internal coating of an aqueous suspension of frit and is then heated to about 200 DEG  F. so that the coating dries and forms a hard and adherent layer.  The blank is then subjected to a number of forging operations at a temperature of about 1800 DEG  to 2100 DEG  F., before which the coating fuses and forms a coherent protective layer. The valve is finally immersed for a few minutes in a bath of molten caustic at about 1000 DEG  F. to remove the coating, leaving a clear, oxide-free inner surface.

[Class 38 (v)] [Also in Group XL] A signal acuating mechanism for use in apparatus for training pilots comprises a number of independently rotatable concentric members, one of which is axially slidable relative to the others, all sliding and rotary movements being effected by one hand and all actuating separate signals. A panel 12 carries a support 11 and a bush 13 through which pass three concentric tubes 31, 36, 42 and 'a shaft 14 all capable of independent rotation. The shaft 14 has a handle 27, and tube 42 has a handle 43 which partially embrace knurled finger pieces 32, 37 on tubes 31, 36 respectively. The three tubes must therefore slide together, and through members 53 and 55, rotate a shaft 56 to operate flight signal control contacts 57. The three tubes 31, 36, 42, when rotated, control the moving contacts 34, 39, 45 respectively of volume control rheostat 35 in marker beacon circuits, of rheostat 40 in the beam signal circuit, and of a rheostat 46 which controls the " left or right " indication of the beam signal. Separate axial sliding of the shaft 14 against a contact spring 20 opens contacts 28, 29 in the beam circuit and closes contacts 28, 29 in a telephone circuit, while rotation of the shaft 14 against a contact spring 18 in one direction closes left-hand contacts 23, 24 and in the other direction closes righthand contacts 23, 24, thus operating inner and outer marker beacon circuits respectively. A pointer on handle 43 co-operates with a dial 47 on the panel 12, and handle 27 co-operates with markings on the handle 43. With this switch an instructor seated either in an aeroplane or at the desk of a link trainer can control signals to be observed by a pupil in the aeroplane.
