    Abstract: Disclosed is a method and fixture for applying a thin layer of polymer material to a piece of wavy sheet metal, so that the layer may function as a backer during electron beam drilling. The sheet is drawn to the smooth surface of a fixture using a vacuum, and polymer is flowed across the surface using a curved leveling board, which produces a generally uniform thickness molding. The edges of the backer are molded with a bevel edge by shaped side rails, to provide a relief around the edge of the backer layer. Thus a raised up portion usually occuring at the edge rail will not interfere with the precise spacing which the backer is intended to produce between the sheet and the workpiece holder during electron beam drilling.

    Abstract: An improved method for manufacturing a heat transfer assembly particularly useful as a component of a radiator used to remove heat from the coolant of an internal combustion engine. The heat transfer assembly includes a plurality of louvered fin strips having fold edges that are in heat transfer contact, through solder joints, with flat-sided tubes designed to carry the fluid to be cooled by a flow of air contacting both the exterior surfaces of the tubes and the fin strip surfaces. The improved method involves the application of beads of solder to the fold edges of the fin strips, rather than to the tubes as in the prior art, before assembly of the fin strips and the tubes. The improved method reduces the amount of solder required and thereby reduces manufacturing cost.

    Abstract: 740,474. Making clad plates. CHICAGO BRIDGE & IRON CO. March 17, 1953, No. 7304/53. Classes 83 (2) and 83 (4). Brazing; welding.-In the cladding of a metal plate 20 with another plate 24, the two plates are superposed with a layer of brazing material 23 between them, and the space between the plates is sealed and is then evacuated through a connection 27, and whilst maintaining the vacuum, the plates are heated to the fusion temperature of the brazing material, thereby causing the latter to melt and effect a seal. The edges of the plates are sealed such as by a weld 26. The base-plate 20 is preferably mild steel and the cladding plate 24 is a corrosion or heat-resistant metal or alloy, e.g. stainless or chromium steels, nickel, nickel alloys or aluminium. A stainless steel base-plate may be clad with copper or a mild steel base-plate may be clad with another mild steel plate. The brazing material may be copper, bronze, or alloys of copper and silicon or copper and phosphorus; for cladding steel with aluminium a copper-aluminium-silicon alloy is used. This brazing material may be in the form of powder, film or foil, ribbons or rods or preferably in the form of a foraminous screen. The mating surfaces of the two plates are cleaned by sandblasting and preferably also by washing with hydrochloric acid. The surfaces of the brazing material are cleaned in a similar manner or, in the case of copper, with methyl alcohol. The plates are heated in a gas furnace and the vacuum is continued until the assembly has cooled below the solidification temperature of the brazing material. Slow cooling of the plates causes them to be annealed. Due to the weld 26, the plates 20, 24 will be spaced further apart near the edges when the cladding is completed. This margin may later be trimmed off. The connection part 22 may be plugged or eliminated by trimming. In another embodiment, Fig. 4, the edges of the two plates 30, 32 are sealed by a flexible metal plate 37 welded to the edges of the two plates. A connection 34 leads to a vacuum pump and a second connection 36 may also lead to a vacuum pump or preferably it is connected to a source of non- oxidizing gas such as argon, helium or hydrogen. In this embodiment the plates 30, 32 will be spaced a smaller distance apart at their edges. Two sets of plates may be clad simultaneously, Fig. 6 (not shown). Clad plates may be welded together at their edges, Fig. 7 (not shown), different weld metals 73 and 74 respectively being used for the base metal and cladding metal. In another embodiment, Fig. 8 (not shown), the cladding plate is not welded at its edge to the mild steel base-plate but is covered by another mild steel plate which is edge-welded to the base-plate. Specific examples are given of the cladding process for various metals of various dimensions including the temperatures used for melting the brazing metal.

    Abstract: 675,564. Soldering and brazing. BRITISH THOMSON-HOUSTON CO., Ltd. May 9,1949 [May 11, 1948], No. 12330/49. Class 83 (iv). Metal parts are clamped together prior to brazing by clamps made wholly of brazing metal and the assembly is heated to fuse the brazing metal and effect brazing. Clampshaped pieces 3 of brazing material are fixed to the sheet 2 by spot-welding, for example, thus holding the tubing 1 in place. The assembly is heated to fuse the pieces 3 and fillets 7 and 8 thus braze the tubing 1 to the sheet 2. The pieces 3 may be of any length and the brazing operation may be carried out without a flux if a reducing atmosphere is used.
