    Abstract: 1,102,745. Making beams; welding by pressure. AMERICAN MACHINE & FOUNDRY CO. 16 July, 1965 [4 Aug., 1964], No. 30371/65. Headings B3A and B3R. Forming a metal beam includes advancing a web strip and a flange strip past a weld point with a V-shaped gap therebetween, applying high-frequency current flow on the edges of the gap, applying pressure to bring the strips into welded engagement at the weld point and guiding the flange strip in a curved path prior to the weld point so that its trailing end is constrained to follow the curved path to prevent premature closing of the V-shaped gap. A weld strip 10, Fig. 1, is pushed by rollers past a weld point w and a succession of flange forming strips of finite length 11, lla are pushed by rollers through a stationary U-shaped curved guide channel 20 to meet the web strip at the weld point where rollers 12, 13 press the members together. Current of a frequency of 50 kc. per sec. or possible 300 or 400 kc. per sec. is applied by contacts 15, 16 to the web and flange members to flow along the V-shaped gap between them to the weld point. In a modification the web strip is drawn from a coil, the flange forming strips are engaged on their top and possibly also lower edges by rollers in the U-shaped guide member and guide rollers are provided in advance of the guide member. In another embodiment the web is also formed by strips 10a, 10b, Fig. 3, of finite length which are guided by rollers 42 and closely adjacent the weld area by a guide member 43. A guide means may engage the flange beyond the weld point. In another embodiment flanges may be welded simultaneously to both sides of a web, the flanges being of finite or continuous length and the web being of a continuous length. The welded beam may be cut into lengths by a saw &c. The ends of the flange pieces may be shaped to engage only at the middle and the ends of web finite length pieces are shaped to engage only at the ends. To ensure that the very ends of the web and flange are welded lugs are welded thereto and after welding cut off and re-used. A modified flange guide member employs rollers 97, Fig. 10, incorporated therein to project a small amount therefrom. Reference has been directed by the Comptroller to Specification 857,197.

    Abstract: A semi-automated beam cutting machine simultaneously cuts with two torches the flanges of the beam in a presettable plane in each of two axis. The web of the beam is cut with a further torch in response to a template, to obtain two rat holes and the inset web edge. Independent angular reorientation in a third plane of each of the flange cutting torches accommodates for lack of perpendicularity between each flange and the web to obtain a true edge and a constant width angle cut. The ends of two beams formed from a single beam can be cut in a single operation with appropriate adjustments to the machine. A method for performing various end cuts of a beam is disclosed.

    Abstract: A process for connecting flat, film-like components to a printed circuit board includes providing the printed circuit board with through-plated holes whose plating includes a fusible material and extends to contacts on the printed circuit board, positioning the flat, film-like components on the board so that the junctions of the components touch but do not extend into the holes and contacting the printed circuit board on the side opposite to the side with the components with liquid solder which rises in the holes, heats the plating and the junctions and bonds the components to the printed circuit board.

    Abstract: 1,137,165. Making flanged beams; welding by pressure; angular bending. NIPPON KOKAN K.K. 15 April, 1966 [15 April, 1965], No. 16729/66. Headings B3A, B3E and B3R. An apparatus for rolling I-shaped beams comprises rollers 2 which feed and straighten a main metal strip A and two narrower strips BB 1 from separate coils in overlapping relationship past rotary electrodes 3 which weld the strips together after which the strip assembly is fed past opposed pairs of flanged rolls 4, successive pairs having thicker flanges which serve to separate the strips along their outside edges. The upper feed rollers 2 each have a pair of flanges 29, which position the strips relative to each other. After the strips have been welded together at a position spaced from the edges, the edges open slightly leavng a gap therebetween as a result of thermal deformation. The pairs of flanged rolls successively open the gap further. The strip assembly then passes through an I-shaped pass between a pair of vertical rolls (6 1 ), Fig. 9 (not shown), and a pair of horizontal rolls (5 1 ), (5 11 ). Each pair of flanged rolls 4 has a pair of rolls 5 co-operating with them to ensure the strip is fed uniformly. The position of the rolls 4 is adjustable laterally for various sizes of strip and the number of pairs of flanged rolls may be varied. One or more of the rolls 5 may be driven.
