Abstract: Sealing system of a device for allowing the passage of a medium, in particular in the high pressure range, is provided with a housing that has a bore hole, a component mounted within the housing such as to oscillate and/or rotate and with a pressure chamber formed within the bore hole. A sealing element surrounding the component adjoins this pressure chamber which can be charged with the medium. An additional metal seal is formed here by the housing and a pressure disc surrounding the component. The outer region is thus tightly closed after the sealing element. In this way, the sealing element is completely tightly encapsulated on the outside.

Abstract: The disclosed device disperses a substance in a liquid. The device has at least one dispersing chamber, which has at least one liquid inlet, at least one substance inlet, and at least one outlet. At least one driving means is placed inside the dispersing chamber while serving to set the liquid inside the dispersing chamber in motion so that at least one cavity with varying volume forms in the liquid for drawing in the substance through the substance inlet and forcing the substance made wet with liquid through the outlet.

Abstract: This invention relates to a method for the mechanically protective production of finely dispersed micro-/nanoemulsions with narrow droplet size distribution, whereby drops are produced on the surface of a membrane or of a filter fabric, and the drops are detached from the membrane or filter fabric surface by motion of the membrane or of the filter fabric in a first immiscible liquid phase in which pronounced stretching flow components in particular, besides shear flow components, bring about the detachment of the drops formed on the membrane surface especially efficiently and protectively. The invention also relates to a device for implementing the method according to the invention with a membrane or filter unit that is positioned to move, in particular to be able to rotate, in a housing with a gap that may be eccentric toward the inner wall of the housing and/or provided with flow baffles that produce stretching flow components.

Abstract: A tensioning device for a sliding gate on the nozzle of a metallurgical vessel includes for the spring mounting of the tensioning device between a gate housing and a housing cover by means of clamping units that connect such two members and that are hinged, to the housing and cross under housing cover 30 bending springs as hinging shafts for clamping units. This results in a simple construction of the tensioning device due to the two modes of operation of the bending springs.

Abstract: A pivot assembly for pivoting a cover member to a housing of a sliding closure unit includes a pivot shaft supported by the housing and connected to the cover member with play therebetween, such that upon pressing the cover member toward refractory plates of the sliding closure unit, respective sliding surfaces of the refractory plates are free of binding and are maintained substantially in uniform surface-to-surface contact. An auxiliary pivot is formed on the cover member to define a pivot axis parallel to the axis of the pivot shaft. Control members connect the pivot shaft to the auxiliary pivot to maintain a constant spacing between the pivot axis and the axis of the pivot shaft in directions parallel to the direction of movement of a movable refractory plate of the sliding closure unit. As a result, displacement of the cover member relative to the housing due to friction between the sliding surfaces of the refractory plates is prevented.

Abstract: A sliding closure unit includes at least one stationary plate having therethrough a discharge opening, and a movable plate mounted in sliding contact with the stationary plate, the movable plate having therethrough first and second discharge openings and including a closing area. Guides define alternative first and second paths of movement of the movable plate in directions along respective first and second tracks extending between the closing area and the first and second discharge openings of the movable plate. A single drive is connected to the movable plate for moving the movable plate along a selected such path between a closed position whereat the closing area is aligned with the discharge opening of the stationary plate and a selected open position wherein one of the discharge openings of the movable plate is aligned with the discharge opening of the stationary plate.
