Title: Wire coil layer speed control - by speed increase in synchronism with drive rolls speed
Inventor: DELLING HEINZ DIPL ING
IPC: B21C47/26
Filed: 1980-06-21
Abstract: In a wire rolling mill, the speeds of the drive rolls and of the wire coil layer are increased in synchronism and in the same ratio. The summing point of the speed control circuit for driver and layer receives, apart from the desired value and the actual value, an additional desired value which raises the current limitation of both circuits for the duration of the boost. This eliminates the risk of the wire sticking in the layer and applies enough kinetic energy to the wire for the coils to be laid in uniform diameters.

Patent DE-3036965-A1 (DE)
IPC: C02F3/00
Filed: 1980-10-01
Abstract: In the purification of waste water using activated sludge, two conditions must be fulfilled for the development of bacteria and are substantially independent of the time the waste water stays in the aeration tank and of the age of the activated sludge:   - the aerobic portion of the activated sludge in the aeration tank must have an activity which is only such that its oxygen consumption per unit volume and time does not exceed a certain value, and - the amount returned from the final clarification tank must be sufficiently large to compensate by cell division for the proportion of the bacteria lost in the aeration tank with the purified water in the final clarification.   The oxygen activity is adjusted by controlling the density of the activated sludge and the periodic cessation of aeration.
