Abstract: It has now been shown that it is possible to produce, at low cost, water for house-hold use from saline raw water with the aid of a system which provides water with at least two different salt contents. Saline raw water is transported to a pre-desalination unit which reduces the salt content down to a predetermined level, but not to the low level required for drinking water. This utility water can be used as it is, for flush toilets, washing, dishwashing, watering, etc. A portion of the utility water is transported to a fine desalination unit for production of drinking water. A portion of used utility water and drinking water can also be returned to the pre-desalination unit for production of new utility water.

Abstract: The present invention relates to a method of producing an impregnated wooden product from a wooden article. The article is pressed isostatically with a pressure exceeding 1,000 bars in a first method step. The wooden article is then placed in a bath containing a liquid-impregnating agent in a second method step and allowed to swell so that at least a part of the impregnating agent is absorbed by the article. The method may optionally be supplemented with a third method step in which the article is pressed isostatically with a pressure exceeding 1,000 bars, so as to form a hard element. The third method step may alternatively be applied to a conventionally pressure-impregnated article.

Abstract: An air filtering unit for preparing highly purified air comprising: a) an inert separation filter for removing solid particular matter, b) a filter element comprising solids adsorbing molecules by using van der Waal forces; c) a filter element comprising molecular sieves; and optionally d) a filter element having the ability of binding polar, acid or basic molecules.

Abstract: A method for producing hard elements from wood provides that at least one wood piece is inserted into a press together with a liquid absorbing material after which an isostatic pressure higher than 800 bar is applied on the wood piece and the liquid absorbing material, the pressure is released and the resulting hard element and the liquid absorbing material, which during the press operation has taken up liquid pressed out from the wood piece, are picked out from the press.

Abstract: An autoclavable multi-layer film formed of thermoplastic materials capable of being processed into hollow shapes and useful for packaging oxygen sensitive materials. The film includes sequential layers A--B--C--D--C--B'--A', wherein the film may optionally not include layer A or A' and the corresponding layer B or B'. A and A' are layers substantially water and water vapor resistant, wherein at least one of the layers A and A' is made of polyolefins, polyethylene terephthalates, or co-polymers of polyethylene terephthalates. B and B' are layers adhesively bonding layers A and A' with layers C. C is a layer of a moisture absorbing polymer substantially impermeable to oxygen. The polymer is selected from the group consisting of aromatic polyamides and co-polymers of aromatic polyamides. D is a layer of a polyethylene-vinyl alcohol with a molar ethylene concentration between 0% and 80%.

Abstract: A method of producing hard wooden elements by compressing wooden blanks at an isostatic pressure greater than 800 bars, preferably greater than 1000 bars.
