Abstract: Abstract of the Disclosure A plurality of vertically extending guide means is carried by the structure of a jack-up type mobile offshore platform.  The guide means is spaced about each of the vertically extending legs which engage the floor of a water-covered area and enable the hull, forming part of the structure, to be elevated and supported in position above the water in the water-covered area.  A first pair of wedges form a first wedge means that is movable vertically in each of the guide means, and a second pair of wedges form a second wedge means that is spaced vertically in each of the guide means relative to the first wedge means.  The first and second wedge means is also movable verti-cally in the guide means.  Means interconnect the pair of wedges which form each the first and second wedge means so that one of the wedges of each pair may be moved to engage a vertical leg chord and thereby lock the legs to the structure and distribute loads and more particularly horizontal loads applied to the structure at joints of the vertically extending leg chords, that is, at the intersection of the vertical leg chords with the respective laterally extending braces between the leg chords.

Abstract: ABSTRACT            In order to avoid producing any secondary waste in the pro-duction of a fibrous and a granular material from house-hold,  agricultural,  forestry waste,  organic waste of the manufacturing and/or service industries, the primary waste first undergoes an opening treatment in an opening unit and then, after removal of any metallic components by mag-netic separation units,  is divided into three fractions.          Such division is effected by a fractionating unit into (a) a fine fraction not exceeding the required final product particle size, (b) a coarse fraction easy to process mecha-nically, and (c) a coarse fraction difficult to process me-chanically. The two coarse fractions are then separately reduced to the required final product particle size in re-ducing units  optimally  suited  to the particular  coarse fraction. Then all three fractions are dried to a specific maximum residual moisture content and sterilized in a dry-ing unit by heating and extraction of the resultant steam, are re-united and jointly fractionated by a further frac-tionating unit and air separators into a heavy fraction consisting chiefly of inorganic granulate,  a light frac-tion consisting chiefly of organic fibres, and a dust frac-tion consisting chiefly of organic dust particles.
