A foamed plastic and a method for its production are described. Tne foamed plastic has cavities which consist of open cells or pores. In at least a portion of the cavities, particles of water-insoluble hydrophilic polymer are homogeneously distributed, the particles being swellable to a gel in water. Examples of such polymer particles are granules of cross-linked dextran. The polymer particles are...

The invention relates to a process for making pressed straw briquettes by mixing the unpressed straw with an aqueous slurry containing organic materials. Part of the water in the slurry will evaporate due to the evolution of a large amount of heat during the compression of the straw. As a result, the slurry is extensively sterilized, so that the briquettes can be used without any risk of contamina...

A method of drilling long and straight holes in rocks is based on the use of a drill rig which may be aligned by means of a laser beam and which comprises a hollow drill stem with a pressure device for guiding the drill stem in a correct direction on applying pressure against the wall of the drilled hole. The laser beam is sent into the hollow drill stem towards an optical detecting unit placed in...
