Abstract: A surface, e.g., a concrete surface, is worked by guiding a lance (23) which comprises a water jet mouthpiece (27) coupled to the high-pressure water over the surface in a working path and at the same oscillating the lance transversely to the working path. The oscillation is driven by an eccentric mechanism (30, 31) and has a stable eccentric position when the mechanism is rotated in the one direction and a stable eccentric position when it is rotated in the other direction. The two positions have a different eccentricity and impart different widths to the working. The working depth and the working width can be changed by changing the direction of rotation.

Abstract: An electric fence has a series of posts connected by an elastically-stretchable, electrically-conductive string to form an enclosure for animals. The string has a unique structure which is comprised of electrically conductive and electrically nonconductive threads intertwined around a rubber core material. The threads are braided in such a way that the string may be substantially stretched without the braided threads severing. The elastically-stretchable construction prevents the string from breaking when moving animals collide with the electrified string.

Abstract: Particles which enclose cavities can be produced by adding a water-insoluble solid, liquid or gaseous cavity generating compound to an aqueous solution of matrix material. Subsequent to forming particles by dispersion in a water-insoluble dispersion medium, the matrix is rendered insoluble in water by cooling, by covalent cross-linking or by polymerization. The cavity generating compound is washed out, whereafter the particles can be used as ion exchangers in gel filtration processes, in hydrophobic chromatography or in affinity chromatography, optionally subsequent to derivatizing the particles. The particles can also be used to advantage as microcarriers in the cultivation of anchorage-dependent cells.

Abstract: Viable biomaterial such as animal cells, plant cells, bacteria, algae or fungi are immobilized with retained ability of growth by encapsulation in polymer beads. Encapsulation is carried out by adding the biomaterial to an aqueous solution of a polymer such as agar, agarose, carrageenan, chitosan, gelatin, collagen or fibrinogen, dispersing the solution in a water-insoluble dispersion medium such as soybean oil, tri-n-butylphosphate, liquid silicone, paraffin oil or phthalic acid dibutylester and allowing the polymer to gel.

Abstract: A high pressure apparatus for the manufacture of diamonds includes a pressure chamber formed of holes in annular, disc-like members arranged one after the other and a pair of opposed pressure-exerting members movable into the chamber formed by the holes with compressible gaskets arranged between adjacent disc-like members. The pressure exerting members are frusto-conical and the ends of the holes adjacent these members are similarly shaped.
