Abstract: A method and an apparatus for treating workpieces with a fluid, in particular for cleaning metallic workpieces prior to a subsequent heat treatment are disclosed. The workpieces are positioned in an air-tight washing vessel. The vessel is filled with an immersion bath substantially covering the workpieces and having a temperature of between 50 DEG  C. and 90 DEG  C. After closing the washing vessel it is evacuated down to a vacuum having a pressure being below the saturation vapor pressure of the fluid at the prevailing temperature. Thus, the fluid starts to boil although its temperature is substantially below the boiling temperature of the fluid at atmospheric pressure. After a certain period of time of maintaining the vacuum and the boiling, the vacuum is relieved and the bath is discharged.

Title: Process for transmitting digitised, block-coded audio signal using scale factors
Inventor: BIJE DETREF
IPC: G10L19/02
Filed: 1991-06-27
Granted: 1996-09-12
Abstract: A method of transmitting digitized block coded audio signals includes forming scale factors of the digitized audio signals. The n(k-1) differences are formed from k successively in-time scale factors for each frequency sub-band or for a group of spectral values of the audio signal. The n(k-1) differences are grouped into at least two value classes. New scale factors are selected for each of the n sub-bands or spectral value groups based on a sequence of n(k-1) value classes. Identifying information, including the control information indicating at which locations in the sequence of n(k-1) value classes the selected new scale factors are disposed, is associated with each sequence of n(k-1) value classes. The associated selected new scale factors are assigned to each sequence of the sampled signal values and to the identifying information associated with each sequence of sampled signal values. A transmission pattern of new scale factors is determined separately for each of the n sub-bands or spectral value groups. Lastly, audio signals are regenerated from the sampled signal values and from the assigned selected new scale factors.
