Abstract: The diameter of the supporting-tube of the preform (TQ) can be kept constant by this method, notwithstanding the tube tendency to collapse owing to the high-temperature necessary to reactant synthesis reaction and raw-material deposition. 
<??>The diameter is controlled by generating between the internal and the external tube surface a pressure difference variable in a way inversely proportional to the diameter of the tube itself and to the total gas flow at the input. 
<??>The device (GP) allows the generation of the required pressure loss at the output and the separation of raw-material solid particles from residual gases.

Abstract: In a speech recognition arrangement (Fig. 1), a plurality of reference templates (130) are stored. Each template comprises a time frame sequence of feature signals of a prescribed reference pattern. A time frame sequence of feature signals representative of an unknown speech pattern is produced (115). Responsive to the feature signals of the speech pattern and the reference pattern templates, a set of signals representative of the similarity between the speech pattern and the reference templates is formed (135). The speech pattern is identified (170) as the one of the reference patterns responsive to the similarity signals. The similarity signal generation includes producing a plurality of signals for each frame of the speech pattern, each signal being representative to the correspondence of predetermined type speech pattern features and the same predetermined type features of the reference pattern. The similarity signal for the template is formed responsive to the plurality of predetermined type correspondence signals.
