Date Mar. 14, 1985.A method for automatically controlling the thickness of product emerging from a rolling mill. Signals indicative of total roll force (F), rollgap position (S), angular position of one mill roll (v) and downstream product thickness (h) are utilized to obtain an output signal indicative of roll eccentricity affecting the true instantaneous rollgap position as a function of the measured mill roll angular position. The output signal may be use to compensate an estimate of instantaneous thickness of the product for the purpose of controlling the gap between work rolls. If preferred the output signal may be further processed to obtain an output signal indicative of the periodic roll eccentricity of a set of rolls having a common period of rotation or of a plurality of such sets.

Date Mar. 24, 1988.Method for cleansing gas from solid, liquid and/or gaseous contaminants, by bubbling the gas through a liquid bath (32), and by introducing the incoming gas into a distribution means (14) and causing the gas to pass in part-streams through a multiple of inlet orifices (64) located at progressively increasing depths beneath the surface (34) of the liquid (32). With increasing inlet pressure an increasing number of inlet orifices (64) are utilized for an increasing number of part-streams. The gas flow is passed from respective inlet orifices (64) through connecting means (24, 26, 28) to outlet orifices (31) located at a considerably higher height level (h) than corresponding inlet orifices (64). The gas flow is caused to flow out through venturi nozzles (28) and/or to strike against impinger or striking surfaces (39) with a minimum pressure drop corresponding to said height differential (h). In this way full operational pressure is immediately achieved, as soon as gas is passed out through any of the inlet orifices (64), and an intense mixing of gas and liquid as well as a high cleansing efficiency are guaranteed.

The oscillator comprises a frequency  to  voltage converter (10) for converting the received frequency to voltage, a frequency discriminator (20) for  comparing  the  voltage  with  a reference voltage to discriminate the  input  frequency,  a  drive unit (30) drived according  to  the  discriminated  logic  of  the frequency  discriminator  (20),  a  frequency  selector  (40)  for selecting the oscillator frequency according to  oscillation  time constant, and a  vertical  oscillator  unit  (50)  for  generating vertical frequency according to the selected frequency.
