IPC: B60B3/00
Filed: 1983-05-20
Abstract: A description is given of a method for forming and machining or finishing a disc wheel and of a device for carrying out this method. The disc wheel is formed by welding together a rim and a disc. An upper and a lower clamping mandrel are imparted a shape which corresponds to the shape of the rim shoulder and flange portions on both sides of the rim; these clamping mandrels are brought into contact with the rim shoulder and flange portions while upper and lower spinning rollers are pressed against the outer circumferential portions of the rim shoulder and flange portions in order to shape the latter by carrying out a spinning process involving stabilisation; a hub-receiving hole formed in the disc is furthermore finished by means of a cutting tool (by the removal of material, for example) which is arranged concentrically with respect to the upper and to the lower clamping mandrel. In this way, very high accuracy in forming and finishing of the disc wheel is achieved.

Patent DE-3433410-A1 (DE)
Title: Controller with PI behaviour and with a device for improving the starting-up behaviour
Inventor: PROELS HANS DIPL ING
IPC: G05B11/42
Filed: 1984-09-12
Abstract: In order to improve the starting-up behaviour of a controller with PI behaviour, in addition a D portion is connected to the I portion of the controller as long as the size of the control deviation multiplied by the amplification factor of the P portion is greater than a predetermined value. The control deviation or the control variable serves as input signal for the D portion. The counteracting control of the D portion which is connected to the I portion during starting up is dependent on the speed of change of the control variable. In this way, in the case of relatively large values, the control variable reaches the set value without unnecessary delay and without overshooting. In addition, a limiting device for the control variable of the controller is provided which, when predeterminable limit values are exceeded, feeds a correction signal to the I portion which returns the control variable to the range limited by the limit values.

Patent DE-3502419-A1 (DE)
Title: Rotating float seal
Inventor: WARSCHKE WERNER
IPC: F04D29/14
Filed: 1985-01-25
Abstract: When using so-called motor-driven submerged pumps to deal with flooded cellars or to remove groundwater below the water table, the requirement of a sealing device at the shaft passage between the motor chamber and the rotor chamber functioning satisfactorily is met by disposing around the drive shaft a so-called float which, when the machine is at a standstill, is buoyed up by the water pressure and thus closes the shaft passage located above the float and which, during operation, co-rotates with the rotor, a pressure force which, by virtue of the shape of the float and the casing surrounding it, builds up between the outer float surface and the inner casing surface as a result of the centrifugal force caused by the rotation, preventing water from penetrating as far as the shaft passage. The device does not contain any parts subject to wear and is therefore unlikely to require repair.
