Tubes 12 are welded to a tube plate 10 by weld surfacing substantially the whole of one face of the plate 10, the surfacing connecting the tubes 12 and the plate 10. The tubes 12 may project from, be flush with, or be slightly withdrawn from the surfaced face of the plate 10. During surfacing the ends of the tubes are blocked by plugs 14 which project from or are flush with the ends of the tubes. The plugs 14 may be cylindrical, conical or flanged and of weldable metal or non-weldable material, e.g. copper, tungsten, sand quartz or glass. The plugs are removed by boring or destroyed by impact. The plugs may be tightly fitted or supported by circlips or may consist of flux or other powder supported on slugs held by circlips. The whole face of the plate may be surfaced by submerged are welding overlapping parallel beads using, e.g., twin oscillating wires or a strip as filler material. Alternatively, as shown in Fig. 4, beads may be deposited in two overlapping directions to cover the face of the plate and all or part of the ends of the plugs. In a modification the plate 10, Fig. 8, is disposed vertically and an iron bar 28 is welded to one side of the plate. Adjacent vertical beads 16 are deposited by electroslag welding using an L- sectioned water-cooled copper shoe 26 and a consumable guide 18 consisting of a web joining tubes guiding electrode wires, the guide being located by a zig-zag ribbon or by pads of asbestos. Alternatively consumable guide tubes insulated by asbestos, glass wool or flux may be used. After the plate has been surfaced, the surfacing is machined or bored to expose the plugs. In a further modification the tubes 12, Fig. 12, terminate at a counter-plate 30 spaced from the plate 10 and the space is filled by electroslag welding using electrodes 34 fed through consumable guide tubes 32. Surfacing may also be effected by vertical submerged arc welding.

Abstract: 872,811. Bi-focal lenses. COMBINED OPTICAL INDUSTRIES Ltd. April 9, 1958 [Jan. 9, 1957], No. 851/57. Class 97(1) A process for making a bi-focal lens from a transparent synthetic resin material, comprises deforming a disc so that a convexity corresponding to the near-sight addition is formed on a first side of the disc and a corresponding concavity is formed on the second side of the disc, and machining the second side to a curvature corresponding to the far-sight component. One method of producing a bi-focal meniscus from an intermediate co-polymer of methyl methacrylate and diethylene glycol bis (allyl carbonate) comprises cutting a circular disc from a cast sheet of the material, machining flat a first side of the disc with a diamond tool mounted in a spherical generator, placing the disc between dies 12, 13 (Fig. 1A) with the first side in contact with the die 13, applying heat and pressure to deform the disc, removing the disc from the mould and machining a convex spherical surface on the second side of the disc so that this side has a spherical curve corresponding to the far-sight component while the first side includes the necessary near-sight addition, and finally placing the disc in a second mould with the second side in contact with a concave die and the first side facing a convex die, the latter having a part opposite the near-sight addition of greater radius of curvature than the remainder of its surface. In order to make a bi-focal toric lens, after forming a convex curve on the second side of the disc, the latter is placed in a mould, having a concave die 19 with curvatures 20, 21 corresponding to the far-sight and nearsight components respectively, and having a flat-surfaced upper die 17. The machined convex surface of the disc is placed in contact with the concave die, and heat and pressure are applied, and after removal from the mould, the first surface is machined to cylindrical form. An example is also given of forming a bi-focal meniscus from polymethyl methacrylate, in which, after convexity has been formed on the first side of the disc by moulding, the second side is machined flat, the disc is placed with its first side in contact with a flat plate in an oven, whereby this first side becomes flat, and the near-sight addition is transferred to the second side, and finally the first side is machined to a convex spherical surface corresponding to the farsight component, In order to form a bi-focal toric lens from polymethyl methacrylate, a disc which has been moulded to have a concave surface on its second side and a convex surface on its first side, has its second side machined to a convex spherical curve, and is then placed with its first side on a flat plate in an oven, so that the near-sight addition is transferred to the second side, the first side then being machined to a cylindrical surface:
