Title: Lapped welding of metal edge portions
IPC: B23K13/04
Filed: 1964-08-04
Abstract: 1,028,150. Welding by pressure. AMERICAN MACHINE & FOUNDRY CO. Aug. 4, 1964 [July 26, 1963], No. 30810/64. Heading B3R. In a method of forming a weld between edge portions of metal strip, the edge portions are heated by H.F. electric currents, the frequency being greater than 50 kc./s. and preferably in the range 300-500 kc./s., while moving them along predetermined spaced paths which keep the edges in spaced non-overlapping relation, and the heated edges are brought into overlapping relation at a position shortly in advance of a weld point at which the overlapped edges are pressed together. In an apparatus for performing the method the strip is formed to substantially tubular shape in a mill including a roller 51 and then passes over a carriage 18 which is supported by rollers 19 engaging the inside surface of the tube. Secured to the carriage is a curved tapered shoe 21 which forces the edge portions 13 and 14, Fig. 2 (not shown) outwards so that they are in tension not only in advance of the shoe but between the shoe 21 and the weld point W. The shoe also supports the tube so that fluid cooled electrodes 23 and 24 connected to the H.F. source can be applied with substantial pressure. The radius r of the leading edge of the shoe is 10% greater than the radius m of the formed tube and is 20% greater than the radius of the finished tube 10. The taper of the shoe is such that the edges 13 and 14 are in spaced-apart relation at the heating point and are overlapped shortly in advance of the welding point W where rollers 16 and 17 co-operate to produce a diagonal mash weld. The shoe 21 is made of steatite, alumina ceramic or fired lava. The object of the method is to confine the heating of the tube to narrow bands substantially the width of the opposing surfaces which are brought into overlapping relation. In a modification the shoe 21a, Fig. 9 (not shown), has a step 36 so that the edges 13 and 14 instead of being maintained in the preferred edge-to-edge relationship prior to the point 15, are on opposite sides of a plane 35 extending along the weld seam, and the edge B is raised above the edge 14. In a further modification, Fig. 4 (not shown), the tube is encircled and heated by an induction coil.

Title: Improvements in the manufacture and laying of a bituminous road material
IPC: E01C7/18
Filed: 1933-11-06
Abstract: A loose bituminized stone material for road making is made by coating hot broken stone, chippings &c. with hot bituminous material, preferably a hard bitumen, and after the mass has cooled to approximately the drop point of the bituminous material adding a separating material, e.g. flue dust.  Only a small quantity of separating material, e.g. 3 per cent, is required.  The laying of the material is effected by treating it, preferably in a mixer, with a solvent, comprising, for instance, a solution of two parts of bitumen or tar in one part of benzene, which not only softens the bituminous coating but also bituminizes the separating material.  The drop point is determined by Ubbelohde's method and corresponds to the temperature at which a drop falls out of a small copper vessel.  It usually lies 15-30 DEG  C. above the softening point determined by the Krämer-Sarnow method.
