Abstract: ABSTRACT      A thread structure for use in coupling percussion drill-ing extension rods minimizes the torque necessary to disconnect such extension rods.  This is accomplished by beveling the crest portions of the cooperating thread structures.  The direc-tion of the bevel is such that the greatest intrusion of the crest portions into the complementary portions of the cooperat-ing thread structure occurs immediately adjacent the abutting flanks thereof.  The abutting flanks then wear in such a way that wedging is substantially avoided.  Additionally, the root portions are defined by a continuously curved surface that smoothly extends into a flat surface defining the thread flanks so that fatigue stresses are minimized.

Abstract: A B S T R A C T                  The invention relates to a method and device for cutting a bundle of tubes containing a nuclear fuel into pieces having a preset length so that the fuel can be dissolved in a suitable solution.                The bundle of tubes is introduced into a guide tube in a sheering machine and is clamped by two side clamps within the tube so as to limit the width of the bundle to the diameter of one tube of the bundle. The side clamps subject the bundle to a sideways thrust so that the tubes in the bundle are maintained contiguous without any excessive curvature.  The bundle of tubes is then submitted to a cutting operation at right angles to its major dimension and after the blade has been returned to its i.operative position a safety plate is positioned near the cut section at a distance slightly greater than the forward movement of the bundle between two seccessive cutting operations.  The side clamps are then withdrawn by a limited amount so that the resilience of the tubes causes them to remain in contact with the clamps.      The bundle of tubes is then pushed forwardly after which the bundle is again clamped by the two side clamps prior to the next cutting operation.

Abstract: The apparatus and method of the invention employ a gas torch which has the feature of selective addition of metal powder to the gas flow, in a cyclical pattern of metal-spraying and non-spraying (fusing) utilization of the same torch.  The torch is caused to make short and relatively rapid transverse oscillations of sweep across the width of a swath along the workpiece, the swath developing in the course of a relatively slow feed (e.g., a longitudinal feed) of the torch with respect to the workpiece.  The rate of torch feed and the duty cycle of metal application (vs. non-spraying) are related to the effective width of the metal "bead" thus sprayed, so as to assure (1) overlapping of adjacent beads and (2) fusing of adjacent beads to each other and to the workpiece.  The embodiment which is describe in detail has the almost universal capability of developing such torch-application along a swath of virtually any prescribed course from straight longitudinal (single rectilineal component), to complex curvilinear (combination of rectilineal and rotational components), as for example to apply coating metal to what will become the cutting edge of a helical auger blade.
