Title: Improvements in or relating to methods of producing flat surfaces more particularly in the construction of electrodes for electric discharge tubes
IPC: H01J21/36
Filed: 1936-06-25
Abstract: 479,024. Making cathode -ray tubes; mica. HOLMAN, H. E. June 25, 1936, No. 17646. [Classes 83 (ii) and 83 (iv)] [Also in Groups V and XL] Jointing.-A method of flattening a piece of material, such as a piece of metal mesh or mica used in the production of electrodes, or base supporting or separating members in cathode-ray oscillograph tubes, thermionic valves, light-sensitive cells, and the like, comprises stretching said material while connected to a temporary supporting framework through a cementing material which permits relative movement at a position where excess stress occurs, securing the material to a final framework, and severing the portion so secured from that connected to the temporary framework. A stretching device comprises a base 1 having bars 2 movable thereon by means of screw- and-nut adjustment devices 3. The base 1 and bars 2 are formed from the material sold under the Registered Trade Mark " Paxolin." In the manufacture of a nickel mesh electrode, a portion of mesh is secured to the bars 2 by gold size or other adhesive of which examples are given in the Specification, or by non- drying rubber grease assisted by clamping pressure. The tension is progressively increased as the gold size hardens by movement of the bars 2, the tension being limited by the viscosity of the adhesive. A permanent framework 7, preferably of a low expansion metal such as the steel sold under the Registered Trade Mark " Invar," is then raised by screws 6, and electroplating is effected through the interstices of the edge of the mesh, while the central part is blocked off by varnish, to secure the framework to the mesh. The part attached to the framework is then severed from the surrounding portion. The frame may be secured by soldering. A mica plate, Fig. 4 (Prov.), is fixed in a similar manner, being formed with holes 10 to facilitate hardening of the gold size, holes 11 through which the securing by electrodeposition is effected, and holes 12 to facilitate the final severing. In a modification, a mica sheet 14 is held flat on a flat plate 15 by a block 16 and is heated to 150‹ C., and a temporary frame 13 of low expansion metal having a coating of a wax composition which melts at about 150‹ C. is applied thereto. On cooling, the mica sheet is under tension, and a permanent framework is secured as above. Instead of perforating the edge of a mica sheet, strips of metal mesh may be employed to bridge the edges of the sheet and the temporary framework.
