Abstract: A method for maintaining and using a high concentration of dissolved copper on a surface of a useful article by providing a copper surface without coatings thereon which increase the wetting angle and which isolate the copper surface and which has a surface roughness between 2 and 50 micro inches Ra, so as to kill microbes thereon.

Abstract: A method for preventing or arresting the development and propagation of cracks in the material surrounding a fastener. The method includes introducing compressive residual stresses in the material surrounding the fastener. The compressive residual stresses offset the high residual tensile and applied stresses which the material may be subjected to in operation and thereby prevent or arrest the development of cracks. Using the output of a sensor, the surface treatment apparatus is positioned relative to a fastener. A compression tool is impinged against the surface of the material adjacent to the fastener and rotated around the perimeter of the fastener thereby inducing a zone of compressive residual stress.

Abstract: Hollow decorative tubing fabricated from thin walled metallic stock material, the stock material preferably being stock tubing. Tubing is cold worked to impart any desired design such as simulated bamboo having realistic culm and node characteristics. The tubing is preferably formed into serial or repeating sections, each characterized by the desired design. For simulated bamboo, a realistic node is worked into the tubing between adjacent sections. The invention may be regarded as a method for manufacturing the resultant elongate hollow decorative tubing or, alternatively, an article of manufacture such as a chair incorporating the resultant elongate simulated bamboo article.

Abstract: The embodiment relates generally to a stamping or draw die used for forming a workpiece into a part or component using a first die shoe, a second die shoe and a punch wherein the punch draws the material into a cavity located in the second die shoe. The force is generated during the forming operation are often unbalanced which generates an uneven stress distribution on the component of the die assembly. By varying the position and angle of the guide surfaces located on the punch, first die shoe and second die shoe the stress can be distributed across a greater area of the respective die assembly component to reduce stress concentrations in a localized area and correspondingly reduce the potential for die failure.

Abstract: A tool for deburring cut edges on workpieces has a pressure body in the form of a rolling body, by means of which, as relative longitudinal movement of rolling body and workpiece takes place, pressure can be applied to the burr on the relevant cut edge in the direction towards the workpiece while the rolling body rolls along the cut edge. A machine for deburring cut edges on workpieces is provided with a tool of the above-mentioned kind. In the course of a process for deburring cut edges on workpieces, a rolling body is moved along the relevant cut edge with a rolling motion. In that movement, pressure is applied by means of the rolling body to the burr on the cut edge in the direction towards the workpiece.
