Abstract: A device for control of lighting fixtures, especially in indoor lighting systems intended for installation over the area to be illuminated. A light detector (16) is connected to an electronic circuit (27-29) for control of this. A shield (17) is designed to limit incoming light on the detector so that it comes from an eligible area of measurement. An optical filter (18) placed in front of the detector (16) is found, which primarily transmits light in an area of the spectrum where the relationship between the inherent optical signal and the main optical signal is at a minimum. The detector (16) is preferably constructed of a material with high spectral sensitivity in the area where the relationship between the inherent optical signal and the main optical signal is at a minimum. Moreover, the electronic circuit (29) is designed to calculate a main signal that corresponds to the main optical signal on the basis of the variation in the illumination that is registered during a period of alternating current. This main signal is used as the basis for control of the fixture.

Abstract: In order to be able to mount a suspended ceiling in places where the space between the ceiling and the overlying structure exceeds 40 mm there is according to the invention used a generally known metal suspension element (2, 3) with a T-iron (4,5). On these T-irons (4,5) there are mounted plaster boards (6) in that on the back of the boards there are glued two metal strips (7,8), i.e. one with a backwardly bent edge (8) overlapping one of the flanges (5) and a metal strip (7) abutting on the flange (5) in the mounted position of the board. It is thereby possible to place the boards loosely and to take them down according to requirements without any need of tools. The structure will allow the mounting of an additional insulation layer on top of the boards (6). At the same time the structure will appear as plane ceiling surface i.e. with concealed support profiles (4,5). This simplifies maintenance. With a view to being able to stack the boards (6) the strips (7,8) are so short that the strips are clear of each other and the boards, back to back, are turned 90 DEG  in relation to each other since the strips will then support the boards (6) evenly.

Abstract: The invention relates to a method for preparing particles of gel-forming polysaccharides which can be used as gel matrices for separating different biomolecules, such as proteins or nucleic acids. The gel particles are prepared by dissolving the polysaccharide in water at a temperature above its dissolving temperature, and emulsifying the solution in an organic solvent to form a water-in-oil emulsion, whereupon the emulsion is cooled such that the polysaccharide solidifies and is separated from the solvent. To obtain particles having a very narrow particle size distribution, the emulsification is carried out according to the invention in the presence of an inorganic hydrophobic protective colloid.
