Abstract: Improved method of attaching sleeve-like fittings to a wrapped wire well screen by welding is faster and stronger than prior methods, provides better mechanical sealing, and eliminates changes in the width of the screen slots. The fitting is axially slotted where it is intended to telescopically overlie several wraps of the well screen. The application of weld beads in the axially directed slots causes the fitting to shrink into tight mechanical contact with the well screen and prevents the enlargement of the slots in the well screen which is possible when a circumferentially oriented weld bead is applied.

Abstract: A bracket of generally U-shaped cross-section comprising spaced-apart legs terminating in edges having projections thereon is joined to a cylindrical steel wall by a method that comprises the steps of: (a) locating the bracket so that said edges extend along the length of the cylindrical steel wall and said projections contact the external surface of the wall, (b) projection-welding the bracket to the wall by an operation that collapses the projections, locates the edges closely adjacent the external surface of the steel wall, and provides a gap of V-shaped cross-section between each edge and the external surface of the wall, and (c) then fillet-welding the bracket to the wall by applying a welding fillet to the external surface of the wall and the outer surface of each leg of the bracket in the region of the V-shaped gap.

Abstract: An anode for an electron beam laser is formed by a thin metallic foil which functions both as a laser cavity wall having an airtight seal, and as a window which permits the passage of electrons therethrough into the laser cavity. This foil anode is supported on a frame structure in a manner such that the foil presents a smooth surface for the laser gas flow and the frame structure provides cooling for the anode to dissipate the heat generated by the electron flow. This frame structure includes a plurality of similar side-by-side, longitudinal, substantially flat, web elements which are separated from each other by gaps through which the electrons can pass. The web elements have cooling tubes welded to each of the opposite edges thereof, one of the tubes being capped with a flat strip which provides a flat surface against which the foil anode can be supported.

In one embodiment of the invention, the coupling members are mounted in combination with a pair of tubes, each of the tubes has a radially enlarged ring near one end thereof, which end is butt welded to one of the pipe ends.

Abstract: A wheel for industrial use is constructed of five parts welded together to form a unitary piece. Specifically, the wheel includes a rim defined by a central cylindrical part having flanges welded to its opposite ends and cooperating therewith to define a single deep well. A pair of disks cooperate together to form a drive disk structure of the wheel. These disks are located within the central cylindrical part of the wheel and have convoluted peripheries welded to the cylindrical part. The periphery of one of the disks is located such that it crisscrosses the weld seam between one of the flanges and one end of the cylindrical part and is also welded to the last mentioned flange.

Abstract: A method and apparatus are provided for soldering abutting ends of links of chains of precious metals. The soldering is accomplished by applying solder to the abutting ends, continuously feeding the chain onto a rotating surface such as a rotating table, heating the chain to melt the solder, and removing the chain from the table. The chain is fed at a slightly higher rate than the rational speed of the table to cause the links to be pushed into each other to avoid tensions from developing in said links during the heating step.

Abstract: A method of manufacturing a body of conglomerated particles has a primary step of coating the particles with very fine polycrystalline metal whiskers, which are sintered in place. The coated particles are then mixed with other filaments, of slightly larger size, which form a matrix. This is made coherent by metallic bonding of the filaments together and to the embedded coated particles. The resultant porous body may be compressed to reduce the porosity.
