Abstract: An apparatus for processing a liquid or a paste, particularly a highly viscous or sticky liquid or paste, includes two or more cylindrical storage chambers, and at least one interconnecting conduit interconnecting the storage chambers. The liquid or paste is processed in the interconnecting conduit by a suitable processing device or mechanism that is operably associated with the interconnecting conduit. A piston displaces the liquid or paste from one cylindrical storage chamber to another through the interconnecting conduit, such that the liquid or paste is processed by the processing device or mechanism during its displacement.

Abstract: A heat exchanger for viscous fluids includes a pair of frustum-shaped bodies (1) and (2) providing the heat-transmitting surfaces. The outer body is confined by gate-flanges (3) and (4) through which is inserted a bearing-and-seal housing (5). The inner body has a hollow center shaft (6) extending through the housing (5). The inner and outer bodies have one or more surface grooves (7). The outer body includes a jacket chamber (8) for a secondary, heat transfer fluid. The inner body is hollow, with channels to improve heat transfer, and the secondary fluid enters and exits through the hollow shaft (6). The angular movement of the inner body is also transferred through the shaft from an outside lever (9). The width of the grooves may exceed that of the scraper, allowing for relative radial movement of the scraper inside the groove. An axial force can be applied to increase the surface pressure of the scrapers.

Abstract: A method and apparatus for stir-frying discrete pieces or particles of one or more foodstuffs by heating a surface (14) and bringing discrete pieces into contact with the heated surface through an inlet means (22), transporting said discrete pieces across the heated surface (14) by means of a mechanically driven stirring means and scraping means in the form of a helix (4), the discrete pieces being stirred such that the orientation of same with respect to the heated surface (14) is altered such that the various surface portions of the discrete pieces are brought into heat conducting contact with the heated surface (14), at the same time scraping the heated surface (14) by means of the rim of the helix or by means of special scraping and stirring elements (27) arranged along the rim of the helix such that the entire area of the heated surface contacted by the discrete pieces is scraped mechanically so as to remove any layer of material originating from the foodstuffs and adhering to the heated surface (14) and

Abstract: A choke valve specially used for regulating the flow volume and with it the back pressure of liquids or gas while drilling through shallow gas bearing formations from an off-shore drilling platform. The valve comprises a flexible cylindrical valve element (8) positioned in the valve housing (1) flow passage and where the valve is so designed that the valve element's (8) flow area can be reduced by a radial reduction of the valve element. The flow area of the valve element (8) is equal to or larger than the remaining flow area of the valve. The valve has devices (10;22) for constricting the end of the valve element (8) being nearest to the outlet opening (3) of the valve. The valve element (8) is so long that it is possible to compensate for the wear to which the end is exposed by sliding the valve element against the constricting devices (10:22) or by moving the latter along the valve element as the wear proceeds.
