Abstract: The invention relates to a screen cylinder including a screen plate (12) having contoured grooves along an inflow side and a backing cylinder (14) having a plurality of openings (28) therethrough and disposed on the outflow side of the screening cylinder. The contoured grooves are elongated in the axial direction and are closely circumferentially spaced one from the other about the screen plate (12). In one embodiment circumferentially extending grooves (22) are formed along the outflow side of the screen plate (12) whereby pulp flows through the contoured grooves (22) into recesses and then through the openings (28) of the backing cylinder (14). In another embodiment, the recesses are formed on the inflow side of the backing cylinder (14), the screen plate (12) being provided with elongated slots along its outflow side in registry with the contoured slots. In this manner, increased flow capacity is provided. Additionally, the screen plate (12) is removable when worn for replacement by a fresh screen plate (12) which may then be secured to the backing cylinder (14).

Abstract: A refinery slurry (1) containing water, oil and a solid fraction, is brought into contact with carbon dioxide gas (2) in order to adjust the pH value of said slurry at an acidic value and, in that way, improve the separation, by mechanical means, of a first water phase (4) and a first oil phase (5), from a sludge. The latter is submitted to an extraction with carbon dioxide, under supercritic conditions, in order to separate a second water phase (8) and a second oil phase from a residual sludge (9), which is disposed of. 
     The process makes it possible most water, and, in particular, most oil contained in said slurry to be removed and a sludge to be disposed of, which shows a reduced propensity to the elution of the residual oil.

Abstract: The rotary motion of a driving cam (3) driven by a driving motor (1) is converted into both the upward and downward movement of a deck member (7) and the forward and backward movement of a tray (5), so that the deck memger (7) and the tray (5) can be driven by a single motor. Further, the conversion into the upward and downward movement of the deck member (7) and the forward and backward movement of the tray (5) is performed by the engagement of a pin (3b) of the driving cam (3) with a straight groove (4c) and a circular groove (4d) of a driving lever (4). Since the straight groove (4c) is extended in the tangential direction of the driving cam (3), when the pin (3b) engages with the straight groove (4c), the driving lever (4) receive a force to slow down the opening and closing speed of the tray (5) at the beginning and end of the movement, thereby improving the quality of the loading operation.

Date Apr. 16, 1992.The measurement of electrokinetic potential is of importance in paper-making. A measuring cell (12) for a specific potential known as streaming potential of the kind disclosed in EP B1 0 079 726 is now provided with measuring electrodes (40, 42) of a metal which forms a reversible electrochemical reaction with pure water to oxidize the metal. The electrodes (40, 42) used in the measurement mode in the cell have a film comprising an oxide of the metal electrochemically formed thereover. Such electrodes are found to give more stable and consistent measurement than the stainless steel electrodes used previously. Silver, lead, copper and alloys such as lead and silver are preferred. The measuring electrodes (40, 42) are regenerated within the cell (12) through electrochemical reduction to bare metal, followed by oxidation to re-form the film. This is performed with the aid of auxiliary electrodes (60, 62) in the cell. A control system (50) for the measurement and regeneration mode is described. Excess excursions of the measurement mode voltage are monitored to indicate that the regeneration procedure is to be entered. The measuring electrode (42) in the cell compartment (22) in which the measurement pad is formed is provided with a shroud (13) to protect it during the flushing of the pad from the mesh (14) in the cell.

Abstract: A method of washing an upflow filter between service runs employs a filter bed having a non-buoyant particulate filter layer through which influent to be filtered is directed in an upward direction, and through which liquid employed in the washing operation is directed in an upflow direction. A two-stage washing operation includes the steps of first directing a combination of air and liquid in an upflow direction through the filter layer with the velocity of the liquid being less than the minimum fluidization velocity of the filter layer, for disrupting only some floc retained in the filter layer during a previous service run, and thereafter directing only liquid in an upflow direction through the filter layer at a velocity less than the minimum fluidization velocity of the filter layer for removing disrupted floc from the filter layer while leaving some floc attached to said particulate media of the filter layer. The process most preferably is carried out with a filter bed including a coarse, particulate media flocculation layer for distributing the flow of influent and promoting flocculation.
