Abstract: A method for applying a polymer to a substrate having a first surface and a second surface (such as an inside surface and outside surface). One or more apertures are provided through the substrate, with the apertures linking the first and second surfaces. A polymer coating is applied to the first and second surfaces, with some of the polymer coating flowing into and remaining within the aperture(s). The polymer coating within the aperture(s) serves to link the polymer coating covering the first surface and the polymer coating covering the second surface. The invention also encompasses coated objects made using the inventive method.

A mounting base is positioned so it extends proximate to the upper and lower deck portions and the deck transition portion. A foot operated trolling motor controller is carried by the mounting base and held at a desired orientation.

Abstract: Sections 1 and 2 each in the form of a welded pipe (square pipe) are provided. The sections 1 and 2 are brought into abutment with each other so that the respective end faces 3a and 3b abut each other at a predetermined angle .beta. between each section and its axial direction. The sections 1 and 2 are arranged symmetrically with respect to each other. Acute end portions of the abutted portion are chamfered to from a plane part. Corners of the sections 1 and 2 are rounded. In such a combined state of both sections, the abutted portion is welded in the circumferential direction to form a weld bead. As a result, penetration of weld metal to the section 1 and that to the section 2 become equal to each other. Thus, it becomes possible to fabricate a welded structure having a uniform weld bead and having improved strength and reliability of welded portions.

Abstract: A method of forming lengths of pipe for assembly together to form fluid flow conduits includes the steps of providing a pipe having a first inner diameter and a central longitudinal axis, providing a ferrule which has an annular first end, having an inner diameter equal to the pipe inner diameter and having a second end formed into a flange adapted to form a flange coupling when abutted against and connected to another similar flange. The flanges have end faces countersunk approximately 1.degree. to 5.degree.. The first end of each ferrule is welded to an end of a pipe, whereby the end face of the flange assumes an orientation wherein the end face is substantially normal to the central longitudinal axis.

Abstract: A method of superplastically forming a metal article and an article formed by such a method are provided. The method includes the steps of placing sheet material including at least one sheet of superplastically formable material (2, 3) and a sheet of reinforcing material (10) adjacent a said sheet (2) of superplastically formable material within a mold tool having a male former (18) protruding from the tool surface positioned to contact the sheet of reinforcing material during forming and causing the at least one superplastically formable sheet (2, 3) adjacent the reinforcing sheet (10) to be superplastically formed into conformation with the surface (28) of the mold tool and simultaneously to urge the sheet of reinforcing material (10) against the male former (18).

Abstract: A process for making a metal wall enclosure of a package for housing an electronic element. An elongated strip, to be formed as the metal sidewall of the enclosure, and a bottom plate, for closing an open end of the metal sidewall, are formed from a sheet of metal stock. At least one aperture is selectively provided in at least one of the bottom plate and the planar metal strip. The strip is prepared for folding, such as by transverse grooves formed in the strip along predetermined fold lines corresponding to corners of the metal sidewall, to facilitate folding of the strip into the desired configuration of the metal sidewall and with the opposite ends of the strip, as folded to form the metal sidewall, in abutting relationship.

Abstract: A method is disclosed for easy and inexpensive fabrication of fold-up frames having diverse geometric configurations for flat packs (metal packages) for housing discrete and integrated circuit chips. The method includes a first step of cutting a piece of flat metallic stock to predetermined length and width consistent with the number of fold-up frames and the perimeter required for the specific fold-up frame configuration to be fabricated, respectively. The flat stock is then milled to form a plurality of grooves of predetermined angle lengthwise in at least one major surface thereof to define the number of sidewall members in the final configuration of the fold-up frame. The milled flat stock may then be sliced to form a plurality of individual milled frames each having the predetermined height required by the specific configuration fold-up frame. Apertures are formed in the milled frame by punching or piercing all sidewall members simultaneously in a single operation.

Abstract: A sheet material assembly for forming a fascia assembly, raised roof edge assembly, coping assembly, or other such building component assembly, is disclosed. Such assembly includes at least a longitudinally-extending generally vertical outer face member, and frequently a longitudinally-extending, generally vertical inner face member spaced laterally away from the outer face member with an intermediate member disposed between the spaced-apart inner and outer face members to interconnect the inner and outer face members. Preferably, both or at least one of the face members has a flange portion located generally at an upper edge, with the intermediate member or an adjacent portion of the face member being secured to the flange portion. Such an assembly facilitates the forming of an angulated configuration, or a curved arcuate configuration, in order to form a "corner" portion of the assembly.

Abstract: A connection arrangement with profiled parts contains, in at least one hollow chamber in a profiled part, a connecting element by means of which a connection with the other profile part is effected. The purpose of the invention is to provide, at low manufacturing cost, a reliable connection and to eliminate any after-treatment of surfaces in the vicinity of the connection. It is proposed that the connecting element be secured to the web of the first profiled part and that a length thereof projects, prior to welding, beyond the front surface; and that, after welding, the weld-zone be arranged in the hollow-chamber in the second profiled part and be at a distance from the adjacent front surfaces of the profiled parts.

Abstract: An improved housing structure for a large-size free-standing cabinet, and a method of making same. The housing structure employs an upright U-shaped side wall structure joined between top and bottom walls. The side wall structure employs a U-shaped metal skin which is formed in one piece so that the back and side walls are integrally joined together through rounded rear corners, with the front edges of the side walls also being rounded to form front integral edge strips which define the opposite sides of the front opening of the cabinet.

Abstract: In a metal enclosure having a left side wall, a top wall, a right side wall and a bottom wall, at least two adjacent walls among these four walls are formed by folding a single plate as a starting material along predetermined folding lines and closed U-shaped ribs extending substantially perpendicular to said folding lines are formed by folding said walls. Each of said ribs has two rib walls extending in the longitudinal direction of said rib and one of the two rib walls at said front end of each of the two ribs extending toward said folding line is formed longer than the other. One rib wall thus extending longer than the other of said two front ends are fitted together. The connection of said two ribs is accomplished by spot welding said fitted rib walls.

Abstract: An improved mitered joint construction for connecting together mitered ends of two tubular members. One leg of an angled insert having two legs is welded to the interior of one of the tubular members and the other insert leg is trimmed and pressed into the other tubular member to hold the members at a desired angle. The members are then welded together only along the inside edge of the joint. For tubular members having a square cross section, two of the inserts hold the members together at the joint.

Abstract: In each arm of a profiled part a notch is made. The notch has two convergent edges forming an angle substantially equal to the angle to be made with the profiled parts. The notch is designed of such a size that the bending can be easily made by applying a compression stress combined with a folding stress in order to reduce at a minimum the extension of lengthening during the folding without reaching the breaking limit of the material constituting the profiled part.
