Abstract: There is disclosed a technique for tightening threaded fasteners in which values of offset torque, initial tension rate relative to angle, final tension rate relative to angle and other joint related factors are empirically determined by instrumenting a plurality of fasteners of the type ultimately to be tightened. In one embodiment, torque and angle are monitored during tightening. Calculations are conducted, while tightening, to determine the tension prevailing in the bolt at a particular angle of advance. By using the calculated tension value and the particular angle of advance, an instantaneous position of threading advance on the tension-angle curve of the fastener is established. From this instantaneous position, it is determined how much greater angle of advance or how much torque is required to tighten the fasteners to a final desired tension value. The same technique may also be used merely to monitor tightening which is terminated by a different tightening strategy.

Abstract: A method for manufacturing a contoured die wherein a workpiece is formed with depressions extending across the top surface of the workpiece from front to back thereof. The depressions are formed spaced apart from one another to retain flat top surface portions therebetween. Smoothly contoured edge surfaces are then formed on the workpiece in the regions of intersection of the top surface with the front and back surfaces, to produce a die with ridge projections surrounded by top surface portions having a concave elevational contour as viewed in a vertical plane perpendicular to the side surfaces of the workpiece.

Abstract: The plant includes quenching apparatus having cooling means for directing cooling liquid onto a rolled product passing through the quenching apparatus from a rolling mill. The cooling liquid is removed from the rolled product, by a liquid, and optionally, by scraping or brushing. The quenched product is cut up, e.g. by shears, before passing to a still-air cooling area.

Abstract: A metal product, such as a steel strip or a mill roll, is cooled by spraying a coolant towards a surface of the product travelling along a given path, by means of cooling apparatus comprising two hollow caissons arranged one inside the other and rigidly connected together to constitute a unit. The unit is located adjacent the product surface and extends across the path of the product surface. Each caisson has a plurality of holes in a wall which is to face the product surface, each hole of the outer caisson being paired with a coaxially aligned hole of the inner caisson. A coolant sprayer is fixed in each pair of holes. Preferably, the sprayers are supplied with air from the inner caisson and water from the outer caisson, the water being atomized by the air.

Abstract: A hollow drive spindle is rotatably mounted on a base and carries a self-opening threading die; and the spindle is driven by a suitable electric drive motor. An air operated collet chuck is mounted on a carriage, for reciprocating the chuck in longitudinal alignment with the threading die. The apparatus is semi-automatic in operation including an electric control circuit and actuator mechanisms operated in response to movement of the carriage. When the carriage reaches its rear limit position the chuck is opened to release the rod and the threading die is closed. When a rod is inserted in the chuck at the beginning of a cycle, it engages a stop arm so that further forward force on a rod also moves the carriage toward the die. With initial forward movement of the carriage, the chuck is closed on the rod and the stop arm is moved out of interference position.

Abstract: This invention relates to a new and useful continuous rotary and work process apparatus. The apparatus comprises one or more annular turrets arranged on a common axis coacting mechanically in unison and performing a variety of assembly, packaging, or other processes or mechanical functions. The apparatus incorporates an internal cam system incorporating means for performing a multiplicity of mechanical actions within the outer perimeter fo the annular turret or annulus.

Abstract: An efficient and reliable means is provided for removing fastener elements or scoops from the tape-edge cords of a slide fastener chain to form the so-called space section without injuring the cords and beads, wherein carrier tape is held between a pair of holder members in a manner such that the ends of the bifurcated leg portions of fastener chain element are in contact with the ends of the holder members; each fastener chain element is cut and divided at the head portion by a wedge-like cutter blade into two pieces with simultaneous opening of the holder members whereby the bifurcated leg portions are outstretched and the scraping of element debris off the carrier tape is facilitated; and the tape-edge cord is withdrawn into between the two holder members before it is contacted by the edge of the downward cutter blade.

Abstract: A swaging tool assembly for also bending, cutting and flaring tubing which includes a tubing holding block connected to a tool support by a sliding stabilizer bar and a main bar rotated by a speed bar handle. The block has a cutter wheel cooperating with tube guides on the tool support. On the upper part of the support is rotatably mounted a head from which project a plurality of conically configurated flaring ends for flaring by swaging a tube held at one end in a seat on the block. A bending lever with telescopic handle is pivoted eccentrically to the lower end of the support which has tube bending means.

Abstract: A method and apparatus of manufacturing wire rod having a content of silicon and manganese greater than 1.5% is described, wherein the average final rolling temperature in processing the rod is from 870.degree. C. to 970.degree. C. and the rod is cooled in an extended position. The composition of steels utilized in the method is also described.

Abstract: A vehicle-repair apparatus has a floor-mounted generally rectangular track having two long and two short sides that are spaced apart sufficiently to accept a vehicle within the sides. A long portal having a pair of upright leg members and a cross member spans the track between the short sides and a similar short portal spans it between the long sides. These portals can be moved perpendicularly to each other along the respective sides. It is possible to lock each of the legs at the respective side to the track, and to lock the cross members of the portals together. A support can be secured to any of the legs or cross members and a jack in turn can be secured to it to pull or push out a dent in a vehicle standing within the track.

Abstract: A corrugated metal sheet is incrementally bent perpendicularly with respect to its corrugations, by repeatedly transversely indenting upwardly the bottoms of the corrugation valleys so that the indentations extend in lines transversely across the sheet and extend into the corrugation sides which interconnect the valleys and ridges of the sheet. Each line of indentation causes the sheet to bend to some degree without detrimental stretching or drawing of the sheet.

Abstract: Two movable members are selectable positioned to form a passageway for handling dual in-line packages. A wheel, comprising resilient material, and a spreader member are selectable positioned in correspondence with the movable members to engage the leads on either side of the package and vertically straighten them. Lateral straightness of the leads, as well as various other package anomalies, are detected by optical scanning.

Abstract: The inventive method and apparatus make a backout stop for a caulker cartridge having a cylindrical barrel of resin material. The backout stop is formed at the rear end of the barrel as an inwardly oriented hook that has a generally triangular cross-sectional shape. The two exposed sides of the hook are an inclined surface sloping radially inward so a plunger can slide over the backout stop into the rear of the barrel and an abrupt edge extending radially inward to prevent the plunger from backing out of the barrel. The apparatus includes a tool with a socket that fits over the rear end of the barrel and has a resin-forming edge protruding obliquely into the socket to extend along the inclined surface of the hook when the tool is seated on the rear end of the barrel. The barrel and tool are supported on a common axis, are moved into axial engagement, and are rotated relative to each other while pressed together so that the edge plows along the inclined surface and forms the resin material into the hook.
