Abstract: To simplify fitting, securing and cleaning of a water trap to/from a washbasin or sink, there is provided a washbasin valve which has a water trap integral therewith and which forms a unit that can be inserted into and secured to the bottom of a washbasin, therewith a water drainage system can be connected directly to the valve. The washbasin valve is fitted by pushing the valve into a hole in the bottom of the basin and securing the valve therein, whereafter the valve is connected directly to a drain pipe. In cleaning the water trap, the seal is drawn-up out of the valve with the water drainage system still connected. No water will be spilled unnecessarily onto the floor beneath the washbasin in so doing.

Abstract: A device for the combustion of solid fuels so as to provide complete combustion from the start and thereby reduce environmental influence and the generation of carcinogens, includes two chambers interconnected by a ceramic filter, which chambers have one or more heat sources, one chamber being adapted for drying and degasification of the fuel and the other chamber being adapted for combustion of the gas generated on degasification. The heat sources are mainly connected with the solid-fuel device to act at an initial stage until combustion takes place in a normal way so that complete combustion may be achieved from the start.

Abstract: A building construction in which a floor story of the building rests on a foundation which, in turn, lies on the ground. An insulated and separate service space has been created beneath the floor story of the living accommodation, with room for accommodating heating, ventilation, and water supply systems as well as electrical systems. The insulated service space is formed mainly by the floor story of the building, a ground insulating layer, and a surrounding foundation wall. A gap is provided between the insulated service space and the first story with the gap extending along the inside of each foundation wall. A heating source is provided within the service space and exhausts heated air directly into the service space with the heated air flowing upwardly through the gap into the first story area.
