Abstract: Abstract The present invention relates to a method and apparatus for facilitating the discharge of a mass tower or the like and treating pulp in said space. The problem with the prior art technique has been in the transfer of high consistency (8 to 25%) pulp, arriving from the thickeners or the like, from a drop leg or the like further on. Pulp has easily formed arching in the drop leg,whereby the pump has not received pulp. Said problem has been solved by arranging according to the invention a rotor (10) in a drop leg, mass tower or the like (2), which rotor (10) breaks pulp planks (7) and homogenizes the pulp, whereby it flows more easily to the impeller of pump (5).

Abstract: CARD COUNTER AND METHOD OF USING SAME                ABSTRACT OF THE DISCLOSURE    A card counter (10) prints card inventory information locally and communicates with a remote computer (43) for permanent storage and retrieval of inventory information.  A microprocessor controller detects a counting error in response to the actual count failing to match a preset count, failing to match a precount information machine read from a machine readable precount label (130) attached to the cards (18), in the event of a phase error from a pair of parallel scanning card sensor circuits (58, 59) or if the final counts of the two card sensor circuits (58, 59) do not match.  In the event of detection of a counting error, an error indication is provided and entry of the count into an accumulator memory is inhibited.  The preset number is entered into memory by selectively entering an actual count into the preset memory.  A pair of separate accumulators are provided for concurrently accumulating totals of two different groups of cards (18).  The card sensor circuits (58, 59) are digitally filtered by the microprocessor (44) which also automatically performs self diagnostics to reduce counting errors due to malfunction.  Malfunction of a scan drive motor (61) 18 reduced through provision of a slip clutch (Figs. 10A and 10B).

Abstract: A process and device for selectively separating particles from a suspension is disclosed. The process involves: introducing the suspension into a rotating separation chamber in which the flow is regulated so that the angular velocity of the suspension is maintained slightly higher than the angular velocity of the wall of the chamber. The bulk of the flow of the suspension treated is removed from the separation chamber from a peripheral area. The following fractions are removed separately, simultaneously, and if necessary continuously. The heavy fraction is removed from a zone near of the sidewall; the light fraction is removed from a zone nearer of the longitudinal axis of the chamber, than the heavy fraction outlet and if desired, an intermediate fraction may be removed from at least one separate intermediate zone between the light fraction outlet and the heavy fraction outlet. The apparatus comprises a separation chamber having a longitudinal axis, sidewalls and two ends; inlets through the first end for introducing suspension and auxiliary fluid; rotating means for deviating suspension and auxiliary fluid towards the sidewalls outlets for the heavy and the intermediate fractions in the second end of the separation zone; rotating means to collect the effluents from areas nearer the sidewalls to their respective outlets; and a light fraction outlet is provided in the first end of the separation chamber and is colinearly aligned with the longitudinal axis. Rotating means are provided to rotate the separation chamber around its longitudinal axis. Numerous alternative embodiments are described.
