IPC: C02F11/12
Filed: 1998-02-20
Abstract: Pre-thickened raw or foul sludge is heated to 180 deg C, changing the inner structure and the biological components. The solid substances are subjected to a high-pressure dewatering process without further additives and are dewatered to a high level.

Title: Steel-framed building for earthquake zones
IPC: E04H9/02
Filed: 1998-07-22
Abstract: The steel frame uprights (a,b,c) are anchored in concrete piles to allow both partial movement (upright (a)) and otherwise rigidity (uprights (b) and (c)) so the rigid uprights (b and c) change shape via the fitted struts (4) during horizontal ground movements of the movable uprights (a).  The movable upright (a) securement takes the form of a ball joint whose hemispherical ball is firmly welded to a fixing. The joint is screwed to the building frame and also screwed to the pile so the piles participate in horizontal ground movement without tearing the house apart. Upright (a) movably anchored by the struts is held to the main frame by a holder, the struts only bolted to the holder so as to take part in vertical movement of the uprights without breaking up the main frame. The double shell outside walls are hung movably on the frame structure so as to move with this in ground movement and so prevent wall cracks and masonry falls. Security hooks on the struts are pre-assembled to carry the outer beams to which the outer wall of the house is fixed, with the beams fixed to two superposed struts in each case to allow for both vertical and lateral movement. A series-produced ascending shaft leading to the communal building shaft contains all electrical etc. service lines and can be extended per storey on a plug-in basis.
