Patent SE-8304481-D0 (SE)
Inventor: SAALASTI TAPIO
IPC: B01D36/02
Filed: 1983-08-18
Abstract: The invention is concerned with the clarification of waters that contain usable sludge, fibres or equivalent. The objective is to recover the usable material, e.g., as fuel and at the same time to prevent pollution of waters. According to the invention, the separation of the solids, such as fibres and any other utilizable material, from the water takes place so that the water containing solid material is fed into or onto a mobile and utilizable layer of material placed on a perforated moving base, e.g. a wire-bottom conveyor (5), so that this material layer functions as a filter. The invention is in particular suitable for the wood processing industry, wherein the water coming from the barking drum (1) is passed into a clarifier tank (7), from which the water containing fibres is pumped onto a layer of bark material carried on a wire-bottom conveyor (5), whereby the bark layer filters the water passing through the bark layer. Likewise, water containing solids can be pumped from a waterway or clarifying basin into or onto a bark layer placed on a wire-bottom or equivalent conveyor to be filtered there, whereat the solids in the water remain in the bark material and pass along with the bark material, e.g. into a dewatering drum, and the water filtered through the bark layer passes back into the waterway or clarifying tank. The filtered warm "circulating water" collected in the upper part of the clarifying tank (7) is pumped back into the barking drum (1).

Abstract: From a mineral fibre strip supplied in roll form, portions (L) are cut off, the length of which corresponds to the width of a rafter area between rafters plus an oversize designed to produce a clamping effect. Formed in this way, the mineral fibre panels are so inserted into the rafter area that the lateral edges of the mineral fibre strip form the top edge and the bottom edge of the panels. In this way, it is possible to achieve virtually completely wastage-free roof insulation even when the distances between the roof rafters vary considerably, and it is possible to work with material of one uniform and considerable width which is supplied in the form of rolls. By reason of the considerable width of the mineral fibre strip, insulation of one rafter area over its entire length requires only a few mineral fibre panels, with few joints being produced. To facilitate guidance of the cut for separating the portions (L), it is possible to provide on one side of the mineral fiber strip marking lines which can, during production, be generated by a co-rotating roller having linear heated zones.

Abstract: During the administration of NO to a patient, NO reacts with oxygen in the respiratory gas to form NO2. Since NO2 is a toxic gas, minimizing the formation of this gas is important. A previously unknown property of NO has been discovered which means that an initial amount of NO2 is formed when NO and O2 mix. But when NO is added at a plurality of mixing points, the total initial amount of NO2 formed can be reduced. The invention is directed to this new method and to a device (4) for carrying out the mixing method. The device (4) contains a flow regulator (20) for regulating the gas, containing NO, which is to be supplied and a flow divider (24) for distributing the flow and sending sub-flows to the various mixing points (26A-26D). <IMAGE>
