Method for manufacturing a compound pipe the wall of which comprises an inner layer (23) of a first material and an outer layer (24) of a second material. Powders (13,14) of the two materials are isostatically hot pressed to form a cylindrical tubular blank (15) in which the first material (13) forms an inner layer and the second material (14) forms an outer layer, the blank after heating to a sui...

Method in reconstructing blades and vanes in steam turbines at existing erosion damages. After removal of the portion of the blade or vane having erosion damages, a replacement portion of a material that can be easily melt or dissolved, is built up on the blade or vane, said portion replacing the original profile of the blade or vane. Around the blade or vane thus reconstructed a graphite mold is ...

In the manufacture of a multilayer polymer film, the thickness and degree of orientation are simultaneously measured. A beam of infrared radiation having predetermined wavelengths is either transmitted through or reflected by the polymer film to be measured and received by a photodetector. The photodetector provides an electrical output signal which can be analyzed to determine the thickness and d...

The present invention is directed to a continuous process for the production of aqueous polyurethane dispersions by continuously mixing solutions of polyurethanes or isocyanate prepolymers dissolved in an organic solvent with water and subsequently continuously removing at least a portion of the solvent using a circulation-type evaporator. The present invention is also directed to the production o...
