Patent DE-4141086-A1 (DE)
Inventor: KUEMMERLING ROLF
IPC: B21B37/78
Filed: 1991-12-10
Abstract: The invention concerns a method for the automatic monitoring of continuous tube rolling mills, in which parameters governing the rolling process are measured and compared with predetermined reference values to produce process-control signals. In order to improve prior art monitoring methods for continuous tube rolling mills, with the aim of ensuring high manufacturing reliability, with only small variations in the thickness of the tube wall over the length of the tube and more constant wall thickness round the tube circumference, the invention proposes that all process parameters which can be measured directly or predetermined are used to adjust the speed range and/or screw-down setting directly while the indirect measurement of the forces occuring between the mill stands is used as an indication of the non-measurable frictional behaviour.

IPC: B65D45/30
Filed: 1991-12-23
Abstract: The closure for blow-moulded wide-necked plastic drums (2) uses a collar-type solid plastic closure ring (9) which rests against the underside of a solid border (10) which projects radially outwards from the drum wall with spacing below the drum opening, and a counter-ring (11) which is likewise made of plastic and rests on a flange (12) moulded onto the outer edge (4) of the lid at the bottom. Moulded onto the closure rings (9, 11) are retaining sleeves (13, 14) which are distributed over the circumference and engage in corresponding bores (15, 16) in the drum border (10) and in the lid flange (12). The closure rings (9, 11) and the retaining sleeves (13, 14) moulded thereon have conical through-bores (17, 18). To close the lid (1) fitted onto the wide-necked drum (2), tensioning bolts (19) made of plastic or metal are pressed from above by means of a pressing tool into the congruently aligned conical bores (18, 17) of the two closure rings (11, 9), the closure ring (9) resting against the drum border (10) being supported by an appropriate device. By means of the tensioning force exerted by the tensioning bolts (19), the lid seal (8) is pressed against the opening edge of the drum neck (3). <IMAGE>

Title: Method and arrangement for locating metal parts
Inventor: HETTNER HORST
IPC: G01V3/11
Filed: 1993-07-19
Abstract: The invention relates to a method and an arrangement for locating metal parts in the conveyed flow of belt conveyors (band conveyors) by means of a metal detecting device. The object is to determine the position of the metal parts in the conveyed flow with a low outlay and a quite high accuracy. This is achieved by virtue of the fact that after the metal detecting device responds the belt drive is shut down, its start up is blocked and the overtravel of the conveyor belt until it comes to rest is measured by counting pulses generated by the conveyor belt in a manner proportional to the travel; pulse marking is undertaken on the belt conveyor downstream of the metal detecting device as a function of travel; the number of the pulses after the belt has stopped is counted; the location found is determined using the number of pulses with the aid of the pulse marking on the belt conveyor; and the block on the belt drive is lifted after removal of the metal part.
