Abstract: Connectors for optical cables in ribbon form and a process for making such connectors in which metal plates for the enclosing the cable ends are made by cold, plastic flow forming of grooves in the plates with a punch having ridges produced by a process which produces grooves which hold the positions of the optical fibers between the plates within narrow tolerances. In the process, a punch body with partially formed ridges is mounted on a head rotatable about the axis of the body and movable toward a grinding wheel which is movable in a path perpendicular to the direction of movement of the head toward the grinding wheel. After two opposite passes of the grinding wheel along the side of a ridge, the punch body is rotated 180 degrees, and the side of a corresponding ridge on the opposite side of the punch body axis is ground. The process is repeated with movement of the head toward the grinding wheel, which is measured, until the sides of all ridges are ground.

Abstract: The present invention is directed to the determination of the force imposed on a terminal being crimped onto a wire. The crimping mechanism includes a cantilevered member which is deflected an amount that is proportional to the crimping force imposed on the terminal by the crimping bar. The amount of this deflection is sensed by four strain gages which are coupled to the cantilevered member and are electrically interconnected to form a Wheatstone bridge. The output of the Wheatstone bridge is then translated into actual force being imposed upon the terminal.

Abstract: In order to stress relieve exposed portions of plastic welds, and thereby reduce susceptibility of such welds to solvent-induced crazing and cracking, the welded parts are formed with flanges extending outwardly therefrom. These flanges are at least partially joined during welding, their adjoining surfaces providing at least a portion of the welded joint. After welding, the flanges are compressed in a direction transverse to their adjoining welded surfaces, the compression being of sufficient magnitude to exceed the yield strength of the flanges, thereby relieving stresses in the exposed portion of the welds. The flanges may be sheared, as by a blade which provides both transverse compressive forces and compressive forces in the direction of the adjoining welded surfaces. The flanges may be sheared through, so as to enable the sheared off end to be removed, or the shearing may penetrate only through the weld zone, providing a notch, but leaving the flanges in place.

Abstract: A cold metal working process gradually changes the cross-section of a copper band to a wider band having one or more sections of reduced thickness. A hammering tool having a chevron-like protrusion, formed by two convergent elongate ridges with long and narrow flat crests, performs a succession of elemental hammered compressions on the band. The metal band, between blows of the hammering tool, is advanced toward the wider part of the chevron-like protrusion and enables the reduced thickness section to be progressively widened by hammering, with the long flat crests of the two ridges, on narrow strips of the portions of the band adjacent to the reduced thickness section. The material displaced from the hammered indentation at each elemental compression of the narrow strip is displaced substantially laterally and results in a widening of the band without an appreciable increase in the initial thickness of the other portions of the band's cross-section.

Abstract: In a method of manufacturing a rack for a variable ratio rack and pinion steering gear, having a preforming process for preparing a rack blank having a plurality of teeth which are formed to a shape corresponding approximately to the shape desired in the finished rack and a finishing process for converting the teeth to the finished shape by cold forming in a die having a shape which is the exact counterpart of the finished shape, the preformed rack teeth are shaped to have top lands which are level with those in the finished shape and bottom lands that are deeper than those of same. The rack teeth in the preformed shape are all wider at the top areas than in the finished shape, and the ratio of the widths at the root areas of the rack teeth in the preformed shape to those in the finished shape varies in proportion to the variation of the steering ratio such that a rack tooth for a higher steering ratio is given the above-mentioned ratio that is larger.

Abstract: A pipe press having a main press section and at least one end press section aligned with the main section for movement with and independently of the main section. The press is designed to accommodate elongate heavy gauge steel pipe blanks having lengths varying between the length of the main section and the combined composite length of the main and end sections. Because of the independence of the end section relative to the main section, the main section is loaded uniformly, even though a blank may be of a length less than the combined composite length of the press. The end press section is free to move axially relative to the main press section to accommodate elongation of a blank during operation of the press. Actuating cylinders for the press are arranged in paired sets extending transversely of the press dies to provide increased load capacity, without resorting to the use of extraordinarily large cylinders.

Abstract: A procelain on steel printed circuit board includes apertures whose edges are rounded. An aperture is formed by first punching or otherwise making an aperture in the uncoated steel of somewhat larger size than desired, then employing a pair of dies, each with rounded shoulders and a center region of smaller area than the aperture. When the board is placed between the dies with the center region of the latter aligned with an aperture, and pressure is applied to the dies, they engage and round the edges of the aperture. The excess displaced material is forced into space between the original peripheral edge of the aperture and the center region of the dies, thereby decreasing the size of the aperture to the desired size and forming a relatively smooth tapered transition region between opposite surfaces of the board and the outer circumference of the aperture of reduced size. The steel is coated with porcelain after the finished apertures are formed.
