Title: Oil and crease contg. wastes - treated by two=stage acidic flotation and final neutralisation
Inventor: POEPEL FRANZ PROF DR ING
IPC: C02F1/52
Filed: 1978-10-09
Abstract: Industrial alkaline wastes with an oil and/or grease content are treated with demulsifiers and acids (pH-value of 4-5). The oil and/or grease is removed in a first flotation stage as froth. In the second flotation stage, surfactants and detergents are turned into floats and are recycled to the first stage. The water outflow from the second stage is finally neutralised by adding an alkaline soln. This system produces oil and grease with little moisture content so that they can be processed immediately in refineries or burned in combustion chambers. The expenditure for chemicals as well as for power is low.

Patent DE-3002018-A1 (DE)
Inventor: PLOHN GERHARD DIPL ING
IPC: G05B9/03
Filed: 1980-01-21
Abstract: A system for selecting a signal having a median frequency from a plurality of periodic signals of different frequencies. In one embodiment, three such periodic signals are converted into corresponding pulse sequences, each having a duty cycle of approximately unity and a frequency which corresponds to the frequency of its associated periodic signal. An output signal is generated which assumes a first logic state when a positive signal slope of a first pulse sequence, which places the first pulse sequence in a first logic state and occurs while the output signal is in a second logic state, is followed by a further positive signal slope of a second pulse sequence, while the first pulse sequence is in its first logic state. The output signal assumes a second logic state when successively negative pulse sequence slopes occur.

Title: Material folder with brake for material roll - controlled by weight or material
Inventor: WIENEN WALTER
IPC: B65H45/103
Filed: 1980-03-25
Abstract: There is at least one bearing for the axis of the roll of material of fabric, film or the like, with a brake controlled by the loading on the bearing. Specifically, the bearing components are pressed down by the weight of the roll of material against return spring pressure. The roller axis is moved between the brake and a counter piece which are therefore moved apart according to the weight of material. The bearing is at least one roller to support the axis, on a swing axis to allow displacement together with the brake according to material weight. The design prevents material unrolling when the folder is stopped, with only a small surplus coming from the roll.
