Abstract: An articulated assembly for pipelines, including: two articulated sections; wherein one of the two articulated sections engages into another one of the two articulated sections; and a locking body that engages at least in areas between the articulated sections and cooperates with a locking contour on one of the articulated sections and with a locking section of the other articulated section such that a relative movement between the articulated sections is limited; wherein a guide means is provided on the articulated sections such that the two articulated sections can be joined together in a defined rotational position in relation to one another.

Abstract: A crushing segment forming part of a crushing roll of a roll crusher, the segment including a main body to mount at least one crushing tooth. A filler material is interposed between respective first and second mount faces provided at the tooth and main body so as to provide enhanced surface area contact between the tooth and segment and increase the capability of the tooth and segment assembly to withstand significantly high loading forces during use.

Abstract: The invention relates to a coupling arrangement (10) for pipelines, with a female coupling section (20) and a male coupling section (40) as well as a locking element (60) which at least in regions engages between the coupling sections (20, 40) and is secured on a coupling section (20), one of the coupling sections (20) comprising a locking contour (34) which cooperates with a locking contour (64) of the locking element (60), and the locking element (60) having a blocking section (62) which cooperates with a blocking section (52) of the other coupling section (40) such that a lateral movement between the coupling sections (20, 40) can be restricted.

Abstract: A wear resistant component for comminution of particulate material includes a steel body and a leading portion of cemented carbide attached to a front portion of the steel body. The wear resistant component includes a wear resistant coating of a metal matrix composite attached to at least one face of the steel body connected to the leading portion.

Abstract: The present invention relates to a cutting insert for a rock drill bit. The rock drill bit includes a tool body (10) having a front surface (13), and a number of cutting inserts (14), each having a generally cylindrical shank portion. The cutting insert (14) is provided with increased volume portions in its parts being most subjected to wear. The invention also relates to the rock drill bit.

Abstract: There is now provided a roll for hot rolling comprising 70-95 weight %, preferably 85-94 weight %, WC in a binder phase consisting of only cobalt or alternatively a Co--Ni--Cr alloy containing 20-35 weight % Ni and up to 10 weight % Cr, possibly with small additions of molybdenum. The WC grains are rounded with an average grain size between 3-10 .mu.m, preferably 4-8 .mu.m. The maximum grain size should not exceed 2 times the average grain size and no more than 2% of the grains be less than half of the average grain size.

Abstract: The present invention relates to a cutting insert for a rock drill bit and a rock drill bit including such a cutting insert. It has the object of increasing the wear resistance of the cemented carbide cutting insert. The inserts are formed with a generally cylindrical shank portion and a convexly formed outer portion. In one embodiment of the invention, the cemented carbide of the insert includes a number of zones and the border between two adjacent zones describes a non-symmetrical path seen both in a cross-sectional side view and in a cross-sectional top view. In a further embodiment, the inserts are also provided with increased volume portions in the parts of the insert being most subjected to wear.

Abstract: A process for the extrusion of plastic plates with very finely structured surface using an extrusion system which is equipped with an extruder and a three roll polishing stack containing a roller with the structuring surface. The system is designed for coextrusion and the plastic plates are produced via two extruders as a coextrudate CX from a highly viscous basic molding compound BF and a low viscosity molding compound NF which is extruded on BF. The surface of said plates is structured via the three roll polishing stack. Fresnel lenses produced by the process may be used in solar collectors.

Abstract: There is now provided a cemented carbide button for rock drilling comprising a core and a surface zone surrounding the core whereby both the surface zone and the core contains WC (.alpha.-phase) and a binder phase based on at least one of cobalt, nickel or iron and that the core in addition contains .eta.-phase. In addition, in the inner part of the surface zone situated close to the core, the cobalt content is higher than the nominal content of cobalt and the cobalt content in the outermost part of the surface zone is lower than the nominal and increases in the direction towards the core, up to a maximum usually at the .eta.-phase core. The grain size distribution of the hard constituent in the zone with high cobalt content and in the .eta.-phase core is narrow in contrast to a button of the prior art in which the grain size distribution of the hard constituent in the zone with high cobalt content and the .eta.-phase core is wide.

Abstract: A method wherein one or more metal salts of at least one iron group metal containing organic groups are dissolved and complex bound in at least one polar solvent with at least one complex former comprising functional groups in the form of OH or NR.sub.3, (RH.dbd.H or alkyl). Hard constituent powder and, optionally, a soluble carbon source are added to the solution. The solvent is evaporated and the remaining powder is heat treated in an inert and/or reducing atmosphere. As a result, coated hard constituent powder is obtained which after addition of a pressing agent can be compacted and sintered according to standard practice to a body containing hard constituents in a binder phase.
