Abstract: A concrete weldment has a central plate with shear force reinforcing members at both ends of the central plate. There is a pair of outstanding arms extending out from each of the ends of the shear reinforcing members. The shear reinforcing members are twisted approximately 45° so that the outstanding arms are rotated substantially 45°. This rotation preserves the vertical and horizontal shear capacity of the weldment as well as to keep the slab reinforcement means well protected with proper concrete coverage. Each of the outstanding arms has a 90 degree bend at the ends for providing increased pull out tensile capacity of the weldment.

Abstract: Method and apparatus for forming aluminum ingot having shaped ends to avoid alligatoring during rolling.

Abstract: A bonded structure including one or more substrates bonded together with a tackified amorphous poly-alpha-olefin adhesive composition. One method of making such a bonded structure is carried out by applying a tackified amorphous poly-alpha-olefin adhesive composition to one or more substrates at a temperature of about 170 degrees Celsius or lower, and joining the substrates to themselves or to one another. The bonded structure has a dynamic peel strength between about 400 and about 1000 grams per 25 millimeters. The bonding efficiency of the bonded structure renders the bonded structure suitable for incorporation into a variety of articles, including personal care products, health/medical products, and household/industrial product, for example.

Abstract: A partially manufactured contiguous metal joist hanger is provided for field fabrication into the likeness and function of a contiguous joist hanger of a desired shape. The contiguous metal joist hanger comprises vertical flanged mounting brackets and a horizontal supporting seat positionable integral flange bracket for securing wood framing members at an intersecting joint.

Abstract: An improved silicon steel sheet has two lateral ends each having a side edge narrower than the width of the silicon sheet. The side edge has two end points linking respectively to two lateral sides of the silicon steel sheet to form two symmetrical slant edges for reducing tension area of the silicon steel sheet at the side edge. The slant edges and the side edges form two solder zones to anchor the silicon steel sheet for soldering at the initial winding stage and after the winding is completed.

Abstract: A method of producing an elongated member having a main body portion and terminal portions extending form ends thereof includes bending an elongated strip between circumferential faces of first forming rolls and second forming rolls having parallel central rotational axes. The circumferential faces of the first forming rolls include annular main body portion bending sections that form the main body portion in the strip and adjacent transition portion bending sections that form adjacent transition portions in the strip, thereby forming an intermediate stage elongated member. The transition portions have a cross-section that changes continuously from the annular cross-section of the main body portion to a different cross-section of the terminal portions.

Abstract: A method is disclosed of making a billet comprising a mass of compressed swarf jacketed in a tubular jacket. A number of similar indentations are formed in the ends of the jacket. The indentations are symmetrically disposed about the axis of the billet. The indentations terminate at terminal positions spaced from the ends of the billet and increase in depth from the terminal positions to the ends of the billet. Jackets of various materials are envisaged, in particular of stainless steel and mild steel. Where the jacket is of stainless steel tubular end pieces of mild steel in which the indentations are formed may be welded thereon.

Abstract: A mold for the casting of aluminum sow ingots includes a mold box having a bottom wall and side walls that define a generally rectangular mold cavity. The bottom wall includes a central raised longitudinally extending protrusion and side longitudinally extending protrusions adapted to define corresponding depressions in the ingot bottom. The side depressions establish ledges for receiving a pair of fork lift blades or tines entering the ledges from either transverse side of the ingot perpendicular to the ledges. A pair of transversely extending protrusions in the mold bottom wall establish corresponding transverse depressions in the mold bottom that are perpendicular to the central longitudinal depression and equispaced from the central transverse axis by a distance enabling the pair of fork lift blades to enter the transverse depressions from a direction perpendicular to either of the longitudinally extending ingot sides to provide a dual entry feature for ease of handling.

Abstract: An ingot formed as an elongate structure characterized by a rectangular center body and reduced section handle structures on the ends of the body each provided with recesses for receipt of manipulative tools. The rectangular center body moreover, includes performations proximate each handle structure which are useful in storage and for the control of heat transfer for partial melting.

Abstract: An improved process is disclosed for splicing metal shafts, in which a pair of shafts (10, 12 or 44, 46) having transverse end surfaces (30, 32 or 54, 56) preferably substantially normal to the axes of the shafts, are positioned coaxially with an insert (34, 48) positioned between and abutted to the end surfaces. The insert is tapered or wedge-shaped at either end to define transverse contact surfaces (18) which abut the end surfaces of the shafts. The angle (.beta.) of the taper on the insert permits insertion of a consumable arc welding electrode (20) into the convergent space defined between the end surfaces of the shafts and the tapered surfaces of the insert and is large enough to allow the arc welding electrode to be positioned at locations not only sufficiently spaced from both the tapered surfaces and the end surfaces but also sufficiently close to the area of abutment between the contact and end surfaces, to ensure proper welding penetration into the base metals.

Abstract: This disclosure is directed to the cutting of steel pipes and tubes by utilization of a special flexible metal guide in conjunction with a cutting torch. Use of the special flexible metal guide improves the steadiness of the torch, thereby producing a more precise cut.

Abstract: A blank for a stone setting comprising a base and prongs extending radially therefrom, said blank having a planar lower side and a notched upper side, the notches at the upper side defining at the junctions of the prongs with the base hinges which enable bending the prongs upwardly relative to the base to form a stone cage and at the distal ends thereof a seat for the stone and tangs for fixing the stone against the seat. A method of making a setting including making the blank by striking it from malleable sheet metal, removing parts of the sheet metal from around the bank, stripping the blank from the sheet metal, using a punch to force it into a die for bending the prongs and tangs at their notched areas to shape it into a cage. A further method of setting a stone by seating a stone against the seat at the top of the cage and bending the tangs against the stone.

Abstract: An improved self-tapping or thread-forming screw where the thread configuration on the screw end swages or forms the thread in an object to be threaded rather than cutting and removing a portion of the material of the object. The screw is provided with a threaded shank terminating in a tapered thread-forming end having four equi-spaced flattened surfaces separated by four threaded lobes or corners, and each corner is provided with a leading flattened surface in place of a portion of the radius to provide a partially threaded relief area in addition to the full relief areas formed by the flattened sides.

Abstract: Rolled stock of a relatively nonductile material and a powder metallurgical method for its production. A precompact is formed including a body of powder of said nonductile material with generally parallel borders of a ductile metal powder compatible with the nonductile material along two side edges thereof. The precompact is compressed to form a compact of said nonductile metal with borders of said ductile metal and having two generally parallel faces extending between the outside edges thereof. The compact is sintered to form a bordered ingot which is then rolled in a direction parallel to its borders by applying rolling force to its faces. Initiation of edge cracks during the rolling operation is thereby inhibited.
