    Abstract: A watercraft body includes a hull made of an aluminum-based material and a separately fabricated superstructure that is mounted on the hull via adjoining flange plates. To fabricate the hull, frame elements are spot-welded onto the inner surface of initially-flat hull plates or plank elements, which are then curved according to the required hull contour and assembled onto the flange plate. The frame elements are screwed together via gusset plates and transverse beams to form transverse frames, and then longitudinal seams between plank elements are continuously welded from the outside. Additionally, the longitudinal seams may be welded from the inside, for example by temporarily removing gusset plates to allow continuous access to the longitudinal seams. Additionally, stand-offs may form a spacing gap between the frame elements and the plank elements, and an adhesive may fill this spacing gap to adhesively bond the framework to the hull plating.

    Abstract: A method of aligning and duplicating alignment includes welding a washer over a larger opening in a hinge once in an aligned position relative to a vehicle door. The door is mounted into an alignment fixture and the hinges are installed over threaded studs extending from the door. The washer is placed onto the threaded stud and tightened against the hinge, covering the larger opening in the hinge. The larger opening in the hinge allows movement of the hinge relative to the door for alignment. The washer defines an opening with a smaller opening sized to provide relatively little clearance for the threaded stud, and thereby maintain alignment between the door and hinge. The washer is permanently attached by a welding operation to allow duplication of door hinge alignment during reassembly.

The fastener is rotated about its central axis and is axially advanced at a predetermined advance rate into engagement with the workpieces so as to cause plasticization of the workpieces at the interface with the fastener, and to cause the fastener to axially penetrate through substantially the entire thickness of the workpieces. The rotation of the fastener is then stopped, and the plastic zone which surrounds the fastener cools to form a metallurgical bond with the fastener. The resulting fastened joint is mechanically superior to conventional mechanically fastened joints made by rivets and the like.

    Abstract: This invention relates to a method for producing bi-metallic tubing wherein a layer (3,31) of a first metal is metallurgically bonded to the exterior surface of a core component (1,29) of a second metal incompatible for solid state bonding with the first metal by processes other than explosive bonding, the resulting cylindrical bonded composite (15,25) is placed within the bore of a thick-walled tube (33) of a metal compatible for solid state bonding with the first metal and the assembly (39) is heated and expanded by passing it over a profiled mandrel (43). In passing over the mandrel sufficient pressure is developed at the interface between the bonded composite and the thick-walled tube to form a metallurgical bond at the interface. When the first metal is the same as the metal of the thick-walled tube the interface is eliminated and a bi-metallic tube consisting of a single outer layer of the first metal with a bonded lining of the second metal is produced.

The pressure-sensitive adhesive consists essentially of a resinous material having a dynamic modulus of elasticity in the range of from 10.sup.4 to 10.sup.9 dyne/cm.sup.2 as measured at the soldering temperature of the electronic devices with a frequency of applied vibrations of 10 Hz. Preferably, the resinous material has a dynamic modulus of elasticity in the range of from 10.sup.4 to 10.sup.7 dyne/cm.sup.2 and a value for tan .delta. of greater than 0.2 as measured under the above conditions. In this case, the pressure-sensitive adhesive exhibits a self-aligning effect whereby electronic devices mounted out of position on the board are forced to move toward the proper positions by the action of the surface tension of a molten solder.

  • Patent number: 4132342
    Abstract: In a method for producing a hot strip by hot rough rolling, a steel slab heated to a rolling temperature to obtain a steel band, and hot finishing rolling the steel band in a continuous manner, the improvements comprising overlapping a forward end portion of a steel band which is being rolled by the rough hot rolling over a finishing end portion of a similarly rolled preceding steel band before or during the hot finishing rolling step, with insertion between the overlapped portions of the both hot bands of an oxide scale-fusing agent which reacts with the oxide scale present on the opposing surfaces of the overlapped portions by the heat of the overlapped portions and forms a low-melting point substance, fixing temporarily the overlapped portions by means of a metallic nail-like member driven into the overlapped portions, bonding the overlapped portions by reduction, and subjecting the steel bands thus bonded to the hot finishing rolling continuously.

  • Patent number: 4131302
    Abstract: A seal-welded pipe joint mechanically braced by a clamp for preferred use in handling toxic and radioactive materials is disclosed together with a process for joining the same. The joint comprises a pair of abutted male frustroconical skirts, each attached integrally to the pipe segments to be joined and confronting each other at opposed mating and finished surfaces which define a sunken ridge at their periphery. A uniform continuous seal weld of relatively slight penetration seals the opposed mating and finished surfaces at the ridge. The pipe joint is physically secured by a plurality of, for example, three female frustroconical segments forming a circumscribing collet which is circumferentially clamped to the skirt by a plurality of, for example, three tangentially disposed bolts. The abutted frustroconical skirts taper from a broad cross section adjacent the pipe wall radially outwardly to a narrower cross section.

  • Patent number: 4013117
    Abstract: A multi-start involute regenerator matrix disk and method for assembling the same, the matrix disk including a hub mandrel with a plurality of matrix elements, each preferably including a matrix strip and a separator strip, in series orientation, endwise abutment against the hub mandrel and mechanically secured to the hub mandrel by a pair of annular pinch rings pressed into the opposite side edges of the matrix elements with the pinch rings positioned to encircle the hub mandrel radially outward thereof whereby to effect wedging of portions of the matrix elements against the outer peripheral surface of the hub mandrel, the matrix elements spirally encircling the hub mandrel in an involute configuration and bonded together to form a rigid elastic matrix structure.

  • Patent number: 3985279
    Abstract: The invention relates to a method of joining together the ends of tubular metal members by explosive welding and to a permanent, self-aligning backing mandrel for use in the method. The mandrel is in the form of a tubular member having an outer face defining a cylindrical portion and an axially adjacent tapered portion, the maximum diameter of the tapered portion being greater than the diameter of the cylindrical portion. An annular shoulder extends outwardly between the cylindrical portion and the maximum diameter end of the tapered portion, which tapers inwardly away from the shoulder. One pipe end is outwardly flared and fits over the tapered portion of the mandrel and the other pipe end is non-flared and fits over the cylindrical portion, abutting the shoulder. The outer end of the flared pipe end overlaps the non-flared pipe, defining therewith an annular wedge-shaped outwardly-opening space. An explosive is located around this outer overlapping end and is detonated to weld the ends together.
