Abstract: A method has been developed for surface modifications of high temperature resistant alloys, such as FeCrAl alloys, in order to increase their resistance to corrosion at high temperatures. Coating it with a Ca-containing compound before heat-treating builds a continuous uniform and adherent layer on the surface of the alloy, that the aluminum depletion of the FeCrAl alloy is reduced under cyclic thermal stress. By this surface modification the resistance to high temperature corrosion of the FeCrAl alloy and its lifetime are significantly increased.

Abstract: A threaded rock drill element for percussive rock drilling includes a body forming a center axis and having a hardened thread. The thread includes thread crests and thread bottoms and a hardened zone having increased hardness. The hardened zone includes first and second hardened areas extending radially from a crest and bottom (valley), respectively, of the thread, to a boundary curve of the hardened zone. The boundary curve has convex portions extending along the thread crests, and concave portions extending along the thread bottoms.

Abstract: A device for towing a train of carriages of a sorting machine includes a pair of wheels driven by respective motors, which wheels engage a blade arranged below the carriages. Each towing wheel is movable toward and away from the blade relative to its respective motor, whereby the inertia of the member that has to be moved in response to a misalignment of the blade is low.

Abstract: A rotary tool for chip removing machining, for example a milling cutter or a drill, includes a shaft, a holder, and a cutting part. The shaft has a conical seating arranged in its front end. The holder has a slightly conical recess, whose cross-sectional dimension decreases toward the open end of the recess. The cutting part has a slightly conical pin designed to be received in the recess and has a cross-sectional dimension which increases in the direction of the free end of the pin. The recess is formed by a wall which is elastically flexible in a radial direction. When the holder is drawn axially into the seating, the wall is flexed radially inwardly, causing the conical surface of the recess to tightly grip the conical surface of the pin and create an interference fit of the pin in the recess.

Abstract: The pipe coupling of the invention is characterized in that the channel, formed by opposed grooves provided on opposed faces of flanges on the ends of two pieces of pipe to be coupled, is composed of at least one essentially triangular groove in the contact face of each of the flanges; in addition, the channel has at least one radially directed groove whose cross-sectional area is essentially rectangular or trapezoidal. The groove is so shaped that at least one edge directed towards the sealing ring is formed between the last-mentioned groove and the other part of the channel.

Abstract: A drilling tool comprising a drill head fixed to a rotatable drill shaft is provided with a special guide device consisting essentially of roller bodies (balls or rollers) retained in bearing rings positioned on the drill shaft adjacent to the drill head. The position of the roller bodies can be adjusted so that they bear with selected pressure against the surface of a drill hole thereby plastically working such surface.
