Abstract: This patent publication discloses a pneumatically operated roll stop particularly for paper rolls (1) and a method for controlling said roll stop. The invention is based on the concept of providing the outlet line (9) from the work chamber (8) of a pneumatic cylinder ( 7), which is connected to the stop arm (3) of the roll stop, at that side of the cylinder actuated during the braking of the roll (1) motion with a pulse-controlled valve (13) suitable for controlling the outlet flow rate from said work chamber (8) of the cylinder (7). Such a roll stop comprises a frame (2), at least one stop arm (3) adapted to said frame (2) with the help of a pivotal joint (5), said stop arm (3) having a member (4) adapted to its distal end, capable of making contact with said roll (1) to be stopped, further two pneumatic cylinders (7a, 7b) connected by their one ends to said frame (2) and by the other ends to said stop arm (3), and at least one control valve (12), connected by air lines (9, 11) to said cylinder (7), for the control of the function of the cylinder (7). The air line (9) exiting from the work chamber (8) of the pneumatic cylinder (7) is provided with a valve (13) between the cylinder (7) and the air discharge point, said valve (13) being capable of controlling air outflow from the line (9) by way of pulsed open and closed operation of the valve (13).

Abstract: In a method of bleaching medium consistency pulp with ozone using a mixer (12), ozone containing gas and about 6-15% consistency pulp are fed (from 22) to the mixer, and then discharged in a first, preferably vertical, path (14, 16). The mixture of pulp and ozone moves in a first part of the vertical path a time period of about 1-5 seconds at a velocity of about 1-5 m/s so that the gas and pulp do not separate during movement in this first part, and the vast majority of the pulp brightening reaction between the ozone and pulp takes place. This is preferably accomplished by passing the mixture upwardly in a small diameter conduit (14) having a height of about 3-20 meters. Then the velocity of the pulp is slowed while still moving in the first path, preferably by feeding it directly to a much larger diameter (e. g. 1.5-10 times) conduit (16), so the height of the unit may be kept under 100 feet. The pulp flows in the large diameter conduit for about 0.5-5 minutes so that residual reactions take place. The pulp then flows into a second path (27) distinctly different from the first path. <IMAGE>

Abstract: The brewing device comprises a brewing cylinder (9) having a cylindrical bore (10) in which a lower plunger (8) is arranged so as to be freely movable and longitudinally displaceable. An upper plunger (7) is firmly connected to a frame (1). Parallel to the vertically arranged brewing cylinder (9) there is a drive spindle (6) which has guiding means (23). A carrier member (24) connected to the brewing cylinder has further guiding means (25) which are engaged with those of the drive spindle (6). By rotating the drive spindle (6) in one direction or the other, the brewing cylinder is moved upwards or downwards. The brewing cylinder is filled with ground coffee via a funnel (12) which can be pivoted out. In order to determine the quantity of ground coffee contained, the brewing cylinder is moved upwards under time control, at least until a counter force produced by the upper plunger (7) over the compressed ground coffee is as great as the driving force of the spindle. In order to allow the preferred brewing of loose ground coffee, the brewing chamber formed between the two plungers (7, 8) is slightly enlarged again before the actual brewing operation. The device is distinguished particularly by its simple construction with few parts subject to wear, the simple construction being enhanced by the omission of limiting switches as a result of the complete time control of the drive spindle. <IMAGE>
