摘要： Sheet piling and like steel shapes are made in a caliber rolling mill having upper and lower rolls of suitable contour. One of the rolls is axially fixed and the other can be shifted axially in opposite directions so that shoulders of the rolls engage and these positions are stored along with a relationship of axial force and spring constants of the mill frame. The rolling then takes these stored values into consideration.

摘要： A flooring system comprises a preformed composite panel having a first sheet (2), a second sheet (3) and a core of insulating material between the first and second sheets (2, 3). In one case the sheet (2) is a generally flat top sheet and the sheet (3) is a profiled bottom sheet. A floor such as a wood effect floor (5) is laid over the flat top sheet (2). An acoustic barrier layer 6 is located between the floor (5) and the sheet (2). The profiling of the sheet (3) defines channels (7) for location of service ducts/conduits (11). A planar facing (8) is applied over the profiled sheet, bridging the channels (7).

摘要： Rolling mill with computer programmed for absolute lock-on AGC control rolls material having absolute aim gage without using an active thickness gage in the control loop. Computer is programmed to calculate; (a) lock-on length of rolled material, (b) mill stretch using a simplified subroutine, (c) calibration-corrected roll gap, (d) a lock-on thickness error relative to aim gage, (e) a corrected roll gap reference signal as a function of a constant lock-on thickness error and other variable thickness errors caused by changes in mill stretch and roll gap occurring after lock-on, and (f) a rate-sensitive variable gain of the corrected roll gap reference signal to reduce thickness errors to substantially zero as rapidly as possible.

摘要： A ROLLING MILL CONTROL SYSTEM, WHICH USES A LOAD CELL SIGNAL TO DETERMINE THE STRETCH OF THE MILL UNDER LOAD, IS PERIODICALLY RECALIBRATED TO CORRECT FOR DRIFT BY MOVING THE WORK ROLLS INTO CONTACT TO ESTABLISH THE TRUE ZERO SETTING THAT SERVES AS THE BASIS IN THE SYSTEM FOR DETERMINING THE CORRECT GAGE OF STRIP SUBSEQUENTLY ROLLED. A BIASING SIGNAL IS PROVIDED DURING RECALIBRATION TO RELATE, IN A STRAIGHT LINE RELATIONSHIP, THE STRETCH OF THE MILL STRUCTURE TO THE LOAD DETECTED BY THE LOAD CELL IN ORDER TO ENABLE THE RECALIBRATION TO BE ACCOMPLISHED QUICKLY AND WITHOUT HUNTING IN THE SYSTEM AT ANY INDICATED BELOW FACE POSITION OF THE ROLLS.
