Abstract: A screen for the screening of pulp suspensions is disclosed, including a screen basket, a rotor for providing pressure and suction pulses in the suspension to be screened along the screen basket, and a dilution liquid header for supplying dilution liquid to counteract thickening of the suspension during operation. The header forms a tubular channel, which divides the screen basket into at least two parts, extends around the basket, and is provided with a plurality of dilution ejection nozzles. Each ejection nozzle forms a channel including at least two channel sections; namely, an entrance channel section that opens into the channel of the header, and an exit channel section downstream of the entrance channel section, wherein the entrance channel section is substantially wider than the exit channel section.

Abstract: Method and apparatus for displaying an electronic calendar in a scrollable cross-point navigation image having two bars, each containing panels corresponding to a separate folder or entry of the calendar's hierarchy of folders and entries. At the intersection of the bars is displayed the current lowest level and the next upper level, if any. In one embodiment, the next higher level is shown in an adjoining panel on a first bar, the next higher level in a next adjoining panel on that bar, until there are no further higher levels to display, at which point the remaining upper-most level folders are displayed. The second bar displays sub-folders or calendar entries within the folder in the focus panel. Moving in the folder hierarchy causes the panels in the first bar to shift to display all intervening levels through the top level.
