摘要:
A string for musical instrument is disclosed, the string formed from precipitation hardening stainless steel, where Ti has been added to improve the precipitation hardening properties. The string has a superior resistance to relaxation and is corrosion resistant, thus improving its tuning stability and maintaining its tone quality, thus prolonging its service life.

The present invention relates to pharmaceutical formulations comprising a betablocker, in a maintenance dose lower than 50 mg, particularly in the range of 25 to 47 mg, optionally containing a cholesterol lowering agent, in admixture with a pharmaceutically acceptable adjuvant, diluent or carrier, as well as a method of treatment and use of the formulations for the treatment of atherosclerosis and related diseases.
摘要:
A device for use when hardening includes fixture parts (1, 4, 6) between which a workpiece is fixed during hardening. The device's fixture parts (1, 4, 6) are three or more so that two or more workpieces are fixed simultaneously in the device.

A coupling connects a valve structure to a container for enclosing pure gas under high pressure. The neck of the container and the valve structure include cooperating contact surfaces. One of the contact surfaces is convexly curved, or alternatively is of frusto-conical shape. The other of the contact surfaces is of convex spherical shape. A sealing ring is compressed between those contact surfaces. The inner surface of the container is polished to achieve a high degree of smoothness. The container is formed of a top part, and a bottom portion welded to an intermediate mantle.

A recuperator for furnaces includes a set of tubes, which are installed in a secondary chamber (1) which is located behind a main combustion chamber of the furnace and through which hot fumes can pass from the main combustion chamber towards an outlet. The task of the tubes is to recuperate thermal energy from the fumes by bringing a combustion gas to pass through the tubes on its way to burners in the main combustion chamber. The different tubes of the tube set are designed as individual units (8) each one of which is removably inserted in the secondary chamber (1) through holes in the walls (4) thereof. In the mounted condition each tube has a closed portion projecting into the secondary chamber as well as a portion projecting from the outside of the walls of the secondary chamber, the latter portion having inlets and outlets for cold and preheated combustion gas respectively.
摘要:
A stabilizer (1) used in a vehicle is provided by a tubular element (2) with a middle section (3) and two end sections (4a and 4b), where the end sections (4a and 4b) is bent at an angle relative the middle section (3) so that the stabilizer (1) attains a U-shape. Section surfaces perpendicular to the longitudinal/center axes (A3 and/or A4) of the tubular element at the middle section (3) and/or the end sections (4a and 4b) are of a shape where one of two vectors (V1 and V2) in the plane of a section surface is longer than the other, both vectors originating from the center of gravity of the section surface (P), extending to the periphery of the tubular element and being at an angle relative to each other. A method of manufacturing a stabilizer is also disclosed.

A duplex stainless steel alloy has been provided which contains in % by weight:--C max. 0.05--Si max. 0.8--Mn 0.3-4--Cr 28-35--Ni 3-10--Mo 1.0-4.0--N 0.2-0.6--Cu max. 1.0--W max. 2.0--S max 0.010--Ce 0-0.2the remainder being Fe and normally occurring impurities and additives. The ferrite content is 30-70% by volume, balance austenite. The steel alloy is very suitable in the environments that exist at the production of urea, in which it may advantageously replace the austenitic steels used so far.
摘要:
A thin walled tube is disclosed consisting essentially of a precipitation hardenable stainless steel and having a ratio, defined as outer tube circumference C divided by π times the square of the tube wall thickness w, of 90-350. The thin walled tube is highly suitable for use in sport appliance or furniture where weight and mechanical properties are of high importance.
摘要:
A stainless steel, which after nitriding exhibits a hardened surface layer with a hardness of at least 1200 Hv is disclosed. The stainless steel can be in the form of wire, plate, strip, tube and pipe and other geometries, especially complex geometries, particularly useful in applications with high demands on a combination of high strength and/or toughness and wear resistance and as a substrate for coating.
