Abstract: Methods for manufacturing highly insulating connector rods and highly insulating composite wall structures using such connector rods. The connector rods are highly insulating and are injection molded in a single step from an appropriate resinous material or moldable plastic. Discontinuous fibers may be impregnated within the resinous material or other moldable plastic. The single-step molding method yields connector rods having pointed ends for facilitating entry through an insulating layer and a first structural layer not yet cured, and also an enlarged head for receiving an impact from a hammer or mallet or for facilitating gripping by the installer. The enlarged head also provides an anchoring effect within a second structural layer upon curing. The connector rods are manufactured to include a ridge or flange to limit the depth of penetration by the connector rod when inserted into the insulating material when forming the composite wall structure.

Abstract: A selectively hardened nail includes a nail head, an elongated shank, and a tip. A portion of the nail shank is made harder than the remainder by selectively heat treating that portion, and cooling it. The nail has controlled bending properties. The selectively hardened portion does not significantly bend when the nail is fired at a surface using a power driving tool, or during use of the nailed object.

Abstract: A nail for fixing a shoe to a hoof includes a head, and a shank extending from the head generally along a centerline and terminating in a tip. A reaction region is formed in the shank adjacent the tip and has a flattened profile having front and rear surfaces interconnected by respective edge surfaces. In the reaction region the front surface is convexly curved to incline the front surface relative to the centreline of tho shark The edge surfaces converge relative to each other towards the tip, whereby, on forcing the nail into the hoof, the reaction region is adapted to produce a resultant force on the nail. The resultant force is caused by engagement of the reaction with the hoof. The resultant force is adapted to predispose the nail to bend about the rear surface of the reaction region Also disclosed are processes for forming a horseshoe nail.

Abstract: A fastener comprising a shaft having a preselected length for use in fastening at least two materials together. A head extends radially around the shaft at one end. The shaft is provided with an enlarged shaft portion located in proximity to the head. The enlarged shaft portion has a pair of opposite ends, a cylindrical center portion and a pair of frusto-conical tapered portions. Each of the frusto-conical tapered portions extends from the center portion to one of the ends. The enlarged shaft portion has a length less than the length of the shaft.

Abstract: Highly insulating and substantially pointed connector rods used in making highly insulative composite wall structures. At least a substantial portion of the connector rod is injection molded in a single step from an appropriate resinous material or moldable plastic. The connector rod has a first substantially pointed end in a penetrating segment for facilitating entry through an insulating layer and for making abutting contact with a form sidewall when manufacturing a composite wall structure using a cast-in-place method. The opposite end, or trailing segment, also includes a substantially pointed end that makes abutting contact with another form sidewall. A middle or mesial segment resides within the insulating layer, which is sandwiched between two structural layers of a hardenable material, such as concrete. A first ridge or flange at the intersection between the mesial and trailing segments limits the depth of penetration of the connector rod when inserted through the insulating material.

Abstract: Highly insulating connectors used in making highly insulative composite wall structures. At least a substantial portion of the connector is injection molded in a single step from an appropriate resinous material or moldable plastic. The connector has a substantially pointed end in a penetrating segment for facilitating penetration of the connector through an insulating layer and a yet unhardened structural material, such as concrete, that will harden into a first structural layer. The opposite end, or gripping segment, includes arcuate wings for facilitating gripping of the connector during placement in the insulating layer and first unhardened structural layer, and also for anchoring the connectors upon hardening of a second structural layer. A middle or mesial segment resides within the insulating layer, which is sandwiched between the first and second structural layer.

Abstract: A corrosion-resistant, headed fastener, such as a nail for exterior applications, is made from a carbon steel wire pre-coated with a protective, metallic layer having corrosion-resistant properties, the protective, metallic layer being discontinuous at a region on a leading end of the pre-coated wire. After at least part of a protective, metallic cap having corrosion-resistant properties is disposed near the leading end of the pre-coated wire, at least part of the protective, metallic cap is welded to the leading end of the pre-coated wire, so as to cover the region where the protective, metallic layer is discontinuous, by impact welding, as the fastener is formed from the precoated wire in such a manner that the fastener is formed with a shank and with a head, which is formed by deformation of the leading end of the pre-coated wire.

Abstract: Highly insulating connector rods used in making highly insulative composite wall structures are disclosed. The high R-value connector is injection molded in a single step from an appropriate resinous material or moldable plastic. Discontinuous fibers may be impregnated within the resinous material or other plastic. The connector rod has a pointed end for facilitating entry through an insulating layer and a first structural layer and an enlarged head for receiving an impact from a hammer or mallet. The enlarged head also provides an anchoring effect within a second structural layer. A ridge or flange helps to orient the connector rod when inserted into the insulating material and also helps to prevent the collapse of the second structural layer toward the first structural layer.

Abstract: A surgical apparatus is disclosed for attaching adjacent end portions of cutaneous body tissue wherein a pair of opposed jaws have means for moving the jaws toward and away from each other. Body tissue engaging means in the form of sharp tip members extend from each jaw and toward the other so as to engage the opposed portions of cutaneous tissue when the jaws are positioned thereagainst and moved toward each other. The jaws and the tips are arranged to cause the cutaneous tissue to assume an irregular shape at the interface whereby an elongated rod-like member, preferably rectangular in cross section, may be directed generally medially of the interface of the tissue to attach the opposed portions to thereby permit healing. The elongated member may have indentations to improve retention within the tissue. A tapered distal end of the elongated member has a pointed tip to facilitate penetration into the tissue.

Abstract: A fastener comprising an elongate shank having a workpiece engaging end and a driving end. The shank is provided with at least one protrusion characterized by having a leading edge and a trailing edge. The leading edge is oriented in a direction non-parallel to any plane containing the longitudinal axis of the shank. The angle subtended between the leading edge and the longitudinal axis towards the driving end is less than 90 degrees and chosen such that, in use, the fastener may be driven into the workpiece, the angle subtended between the trailing edge and the longitudinal axis towards the driving end being such that the trailing edge resists removal of the fixing member from the workpiece. Preferably the protrusion is welded to the shank.

Abstract: A fastener for use particularly to temporarily secure wood strip members to a concrete substrate includes an upper cylindrical head overlying a first cylindrical shank, with a truncated conical further head coaxially aligned with the cylindrical head, with a second shank positioned between the further head and an elliptical, deformable anchor portion including a third shank underlying the anchor portion. The anchor portion is deformable to enhance securement of the fastener within the concrete substrate, and wherein further the cylindrical head and the further head define a gap therebetween to enable removal of the fastener by application of a tool to the first shank.

Abstract: A hanger adapted to be driven into a wooden frame member includes a one-piece stamped metal member having a head and a flat elongate symmetrical shank with a series of lands and grooves disposed on opposite sides of the longitudinal axis of the shank between its tip and a pair of laterally extending shoulders on its head. Inclined camming surfaces extend between the lands and grooves and cooperate therewith to compress the wood fibers laterally of the shank as it is driven into the wood. A lateral gripping surface behind each land surface engages the wood fibers which expand into the distally adjacent groove to provide a positive gripping action which resists disengagement.

Abstract: Nail-type fastener, comprising an elongated shank (1) with a head at one end, and a point at the other end. The nail shank has three symmetrically placed, longitudinal grooves (4) separated by longitudinal ridges (8) with a cross-sectionally arcuate outer side (9). The grooves have flat, concave or cross-sectionally V-shaped bottom surfaces (27;17;7) and usually side flank surfaces (5) arranged obliquely thereto which connect to the bottom surface via individual corners (6) of small radius of curvature. The cross-sectional shape selected provides a nail with high flexural rigidity and high pull grip with comparatively low weight. The fastener or nail is produced starting from a cross-sectionally circular nail wire stock which is profiled in two coldrolling steps. In the first step, the nail wire passes through a first roller trio, the section rollers of which roll cross-sectionally arcuate guide grooves into the nail wire stock.

Abstract: A nail having a shank and head including one or more spaced grooves formed in the shank about its periphery, such that the nail can be fractured.The groove may comprise any one of several configurations, e.g. rectangular, V-shaped, concave, etc. in cross-section. The essence of the invention is to provide the nail shank with a reduced circumference at one or more locations along its length so that the nail portion above the reduced portion nearest the head will break off on impact from the side, thus leaving the remainder of the nail shank in place.
