Title: Adjustment of three roll assembly defining common calibre opening - involves using triangular and hexagonal patterns to ensure a common focal point for each roll, allowing rapid and accurate adjustment
Inventor: HOLTHOFF HELMUT
IPC: B21B31/16
Filed: 1991-11-14
Abstract: Adjusting the radial positions of three rolls forming a common calibre opening defined by their concave work surfaces, involves using a triangular pattern (11) which can be rotated and moved linerly via the operation of a parallelogramme guide. The patterns of the three rolls are projected onto the pattern (11) and using one roll the pattern (11) is rotated until it achieves a position whereby the roll can be moved axially without its deepest position moving away from a side of the triangle. The pattern is then rotationally locked in position before being linearly moved until the gaps between each deep position and a side of a triangle is the same. The final adjustment is achieved using a six sided pattern whose every alternate corner is aligned with the corner of a triangle. The rolls are then moved in turn until the gaps between the work surfaces and the sides of the hexagon are equal, thereby ensuring a common focal point of the concave work surfaces. ADVANTAGE - Adjustment is rapid and accurate.

Title: Cooling polymer chips in silo - in which air is blown in near bottom of silo while it is being filled or emptied
Inventor: BIEGER EBERHARD
IPC: F26B9/06
Filed: 1992-05-22
Abstract: Polymer chips are cooled in a storage blending silo by blowing gas or vapour through them. The cooling medium is pref. introduced at the bottom of the silo and is blown through while the silo is being filled or emptied. The cooling medium can be conditioned or contain reagents for treating the polymer. Alternatively it can be air. More specifically the exit of a silo has an annular channel which is supplied with air from a fan via a heat exchanger. While the silo is being filled, air at about 40 deg.C enters through a grid and flows in counterflow up through the polymer chips. The polymer enters the silo at about 80 deg.C and the air leaves at 78 deg.C. When compared with a fluidised bed, the air consumption is reduced from 83300 kg/hr to 33000 kg/hr and the power consumption from 82 - 54 kW. USE/ADVANTAGE - Cooling is simpler than using a fluidised bed and consumes less powe
