Title: Looper control regulates looper angle and tension between roll stands - using current or speed control to compensate for variations in roller process characteristics and thereby improve rolling quality
Inventor: SEKI YOSHIRO
IPC: B21B37/50
Filed: 1990-02-06
Abstract: Looper control unit to regulate the looper angle and tension between roll stands in a continuous rolling mill has a looper speed control unit (1) acting on the armature current (1) and another control to regulate the rotational speed of the main motor (5) for powering a roller on a roller stand next to the looper. A section of the control unit integrates the corresponding deviat-ion between the determined actual value and ideal value in relation to the tension and looper angle. A proportioning operation is applied to the corresponding deviations between the tension, the looper operating angle and the rotational speed of the looper motor at the time when the control process starts as well as at the time of current control in order to combine the obtd valuves and to supply the looper current control unit or the looper control unit. A control section effects an integration and a proportioning similar to the aforementioned section, for the purpose of combin-ing the obtained values and outputting the same to the main motor-speed control unit. An optmum gain adjusting unit corrects the proportional gain value in relation to the speed of the main motor. Of two design variations for the control system, one uses a looper current control unit (1), the other a looper speed control unit.

Patent DE-4009146-A1 (DE)
Inventor: LYSEN HEINRICH DIPL ING
IPC: G01B11/27
Filed: 1990-03-21
Abstract: A process for verifying the parallelism of axes of bodies can be carried out simply using low-cost auxiliary apparatus while still yielding highly accurate results. In the process, a measurement beam (L), preferably a laser beam, is emitted perpendicular to the axis of each body (1, 2). When said beams are rotated in succession about the axis of the bodies, they fall on at least three detectors (4a, 4b, 4c, 4d, 4e). Each detector then emits a signal indicating the position of the point of coincidence on a detector axis (5) of the corresponding detector. The spatial position of the axis of each body relative to a reference axis is calculated from the detector signals and the relative position, which may be measured separately, of points of intersection of the body axes and the detector axes with a surface defined by a measurement beam. A device which is particularly suitable for carrying out the process is also indicated.

Title: Method for filling bottles with beverages - involves microwave radiation of bottles prior to filling
Inventor: KRONSEDER HERMANN
IPC: B65B55/10
Filed: 1990-06-06
Abstract: Prior to or during radiation with microwaves, water is sprayed into the bottles, on to their mouth, and over their external surfaces. The water used is sterile, and heated. While the radiation process is in force, each bottle is pressed in a gastight fashion against a filler unit, and is then evacuated, prior to being filled with inert gas. Very little water is used, and for only a few seconds, but the process causes an adequate development of steam for eradication of germs. USE/ADVANTAGE - To sterilise bottles prior to being filled with beverages.

Filed: 1991-02-01
Abstract: In a process for the hydrostatic shaping of hollow bodies (17) of coldworkable metal inside a shaping chamber (16) of a swage (11) and in a device for implementing the process, pressurised liquid is fed from outside into the hollow body (17) and thus the wall of the hollow body is pressed against the engraving of the shaping chamber (17) under relative movement. A simple and rapid method of operation is obtained in that the hollow body (17) is floatingly held substantially without axial force outside its shaping region and shaped solely by the pressurised liquid, which is fed into the hollow body (17) initially in a filling stage at increasing pressure, immediately whereafter it is fed into the hollow body (17) at increasing shaping pressure during a shaping stage. Here, the maximum shaping pressure is a multiple of the maximum filling pressure. During the filling stage the quantity of pressurised liquid fed in per unit time is a multiple of that during the shaping stage. Fig 1

Abstract: The invention concerns a process for dressing brown coal for combined gas and steam processes in heat-generating installations. The aim of the invention is to achieve substantial reduction of the CO2 emission per useful effect unit by reduced use of fossil energy carriers; the devices for drying raw brown coal are to be connected to the heat-generating installation in such a manner that the energy of the exhaust vapours is fully utilized. To this end, raw brown coal is dried and dried brown coal is pyrolysed in two separate filled shaft reactors, but in direct succession; the drying reactor is heated indirectly with saturated steam and the pyrolysis reactor is heated indirectly with live steam (> 130 bar, > 500  DEG C) from a steam boiler with a pressurized-fluidized bed combustor; the coke is conveyed from the pyrolysis reactor into the same steam boiler and the pyrolysis gas, from which the dust is removed in the reactor, is conveyed from the same steam boiler into an additional burner which raises the temperature of the fluidized bed exhaust gases.
