Abstract: This invention relates to an automatic apparatus and method for coupling a workpiece to a specified position along a continuous length of line and then cutting the line to a predetermined length. A length of the line is clamped adjacent a leading section thereof and tensioned over the workpiece to which it is to be fastened. The tension is then regulated for providing slack in the line. Loop sections are then folded into the line and stuffed through one or more one way apertures in the workpiece. Additional tension is provided for unfolding the line within the apertures, thereby coupling the line to the workpiece. The length of line is then moved to another work area for being cut to the predetermined length. An apparatus in accordance with this method is also provided.

Abstract: The method includes the use of a conveyor table mounting press assemblies above and below the table respectively. Coils of connector plate stock having prepunched integrally extending teeth feed upper and lower press platens of the press assemblies, the platens being movable toward one another to substantially simultaneously cut the connector stock to predetermined lengths to form connector plates and embed the teeth of the connector plates on opposite sides of a joint formed by a pair of wooden frame members disposed in end-to-end butting relation on the conveyor between the press assemblies. To join a pair of wooden members end to end in butting relation, the members are displaced forwardly along the conveyor table with the trailing member offset laterally from the leading member until the offset member butts a stop which locates the butt joint in accurate registration between the press platens. Clamp cylinders displace both members against a fence to longitudinally align the members.

Abstract: A method of forming a composite structure having precision surface openings, such as an air foil through which air can be drawn in for boundary layer control. A metallic face sheet is bonded to a base member that is formed with elongate channels which are to serve as air plenums. A protective metal strip is inserted into each channel, and a high velocity water jet is directed against the face sheet at the area of each channel to form a through slot opening. The protective strip protects the base material from the inpact of the water after it passes through the slot being formed.

Abstract: A method for forming an electrical equipment cover, whose temperature will not appreciably increase when used in an environment of high-strength, time-varying magnetic fields, is provided. The cover is formed from a strong, relatively inexpensive magnetic steel which would ordinarily become heated in such an environment by hysteresis and eddy current losses. In order to prevent this heating, a circular blank or disk of this steel is determined and cut. Selected segments of the blank are removed to form slots in a polygonal pattern concentric with the disk and to form slots along a diameter of the disk or circular blank. All of the slots are filled with strips of a non-magnetic metal, preferably of low electrical resistance, which are then welded to the disk or circular blank. The welds are then ground to smooth the surface of the circular blank. Openings for current-carrying bushings are established in the blank to connect ends of adjacent slots.

Abstract: A method of making a multi-V-grooved sheet metal pulley from a flat sheet metal strip. The strip is passed through forming rolls which preform a plurality of generally V-shaped, transversely spaced, longitudinally extending grooves in a portion of the strip, and a generally flat hub wall flange in a transversely adjacent second portion of the strip. The hub wall flange portion of the strip then is notched to preshape the flange prior to circular forming the bottom hub wall of a pulley therefrom. The preformed grooved and notched strip then is severed into individual strips, each of which provides the material for a cup-shaped sheet metal pulley. Each strip then is passed between a pair of wrapping rolls which form the strip into a circular, preferably cylindrical configuration with the strip ends located adjacent to each other. The adjacent ends of the strip then are abutted and welded together, forming a cup-shaped pulley.

Abstract: An improved method for transferring electrical components from a breadboard to a printed circuit board and mounting the components thereon is disclosed, as well as an apparatus for facilitating such transfer and mounting. In a preferred case, the breadboard comprises a solderless breadboard socket. A printed circuit board having a drilled hole pattern and circuit pattern matching that of a solderless breadboard socket is placed over the solderless breadboard socket so that the holes in each are aligned. Breadboarding is done by pushing the leads of various components through the printed circuit board and into the solderless breadboard socket. When the desired circuit is completed, the composite is utilized as one side of a container with the component side forming an inner surface thereof. Particles smaller than the components, such as polymer pellets, are introduced into the container to surround and cover the components and hold the components in place.

Abstract: An improved method for manufacturing an electrical heating device including the steps of placing an electric heating element comprising an electrical resistor, electrical insulation material, and a metallic jacket within a cladding tube, filling the remaining space in the cladding tube with a metal powder having a high thermal conductivity, densifying the powder after the powder is placed in the cladding tube, and subsequently sintering the powder. The improvement of the invention comprises the steps of mixing the metal powder, prior to the step of filling, from grain sizes which produce a high filling density in the cladding tube. The metal powder is then additionally densified, subsequent to the step of densifying previously carried out but prior to the step of sintering, by reducing the diameter of the cladding tube. The diameter of the cladding tube is then further reduced to compensate for shrinkage of the metal powder during the step of sintering.
