The lighting device (1a, 1b, 1c) comprises a diffuse light source (2), a screening device (8) screening off part of the light radiating from the light source (2), and an opening in the lighting device (1a, 1b, 1c), through which the light is allowed to radiate. The lighting device (1a, 1b, 1c) furthermore comprises a lamella device (4) having at least two light absorbing and/or reflecting lamellae...

Marine lifejacket auto-control self igniting guiding light system that only ignites at night and bad visibility once the person or the ring buoy gets into water in a marine accident. It works automatically without chemical reaction between the seawater and the battery contents or by manual button, as currently is the case with other light systems.

The invention concerns a method for the production of nitrate containing products (fertilizers, technical products) from undercooling melts, wherein a XN-water solution is evaporated up to a content of 50-99.8 weight % XN, where X is one or more selected from Ca, Mg, NH, Na and K, and N means nitrate. The preferred range of XN is 70-99.5 weight %. The melt is cooled down to and kept at a temperatu...

The invention relates to a gas chromatograph for the analysis of gas samples. It has a feed arrangement for feeding the sample, an open tubular capillary column for separating the components of the sample, temperature control means for controlling the temperature of the column, and a detector for detecting the separated components of the sample. The efficiency has been improved and a convenient ha...

A permanently connected heat exchanger for receiving three media and composed of two plate types is intended to be used in a boiler. The heat exchanger is designed to counteract and prevent the occurrence of lime deposition (scaling) during the production of hot domestic hot water. The plates of the heat exchanger together constitute cassettes which are stacked on one another. The first plate type...

The present invention concerns a method of producing a lightning diverter for conducting a lightning-induced electrical current, which is to be placed on structures such as wings on wind turbines, aircraft components, radomes and the like with the purpose of lightning protection. The method comprises the steps of making a plurality of holes in a plate of an electrically conductive material, fillin...

An absorbent article for feminine hygiene, comprising: a body contacting layer; a garment contacting layer; and an absorbent core disposed between the body contacting layer and the garment contacting layer. The absorbent core has a core edge. The core edge defines a core region within the core edge and an outer region outside the core region. The body contacting layer and the garment contacting la...

A method of assembling a blade arrangement of a refiner surface of a dis k refiner. A refiner surface (6, 7) or refiner surface block (23, 24) is composed of the blade segments (10) in such a manner that a dimension (B) of the diamete r of the refiner surface or refiner surface block is smaller than the diameter (A) of an assembly opening (12) in the frame (2) of the refiner at least at some point...
