Title: Paper web take=up for drying section of paper mfg. machine - by using suction roller inner chambers with stepless control to set suction action to catch end of web at leader sides
Inventor: PINTER REINHARD DIPL ING DR
IPC: F26B13/16
Filed: 1992-12-09
Abstract: The roller applies a different suction action to the web at the centre of the roller and on continuous working, spreads the suction action over the whole roller width between its opposite ends. The leader, on feeding to the roller, is caught directly at one section(s) of the roller mantle (2) by the narrow strips by suction through the interior of the suction roller (1). The suction action is pref. controlled steplessly. The suction air distribution, in at least the central zone (4') of a single-mantle suction roller (1), is determined by computer control of the vacuum pump drive.

Both end sections (4,4'') of the roller are pref. connected to dedicated vacuum sources for a direct application to the inner side of the roller mantle (2), with controlled blocks to set the suction zone at ends w.r.t. the remainder, and esp. isolate it from the rest of the roller. The control blocks (5,5',11,11') are fitted so each roller end (4,4'') has one of them. ADVANTAGE - The system takes up the leading end of the web cleanly and firmly, and prevents shrinkage by fixing the side zones in place.

Title: Stacking method for loose goods, e.g. coal, onto tip
Inventor: HERKENRATH KARL
IPC: B65G65/28
Filed: 1992-12-19
Abstract: The coal tip is built up in straight lines by moving the jib-arm (3) between an inner (4) and outer (5) point. The height of the lines on which the material is being tipped (8,11,12) is controlled by the speed with which the jib-arm moves.In the case of a continuous flow beginning near the inner or outer point, a slower speed of movement is achieved, and, if the angle of movement is increased, a faster speed of movement, so that the tip-height per line is more evenly regulated. When one level of material is laid, it is compacted, followed by a parallel next level carried out by the jib-arm.
