Title: Speech encoding and decoding capable of improving a speech quality
Inventor: TAGUCHI TETSU
IPC: G10L19/00
Filed: 1992-12-15
Abstract: In an encoding/decoding device operable in response to an input speech signal by means of an adaptive transform coding to produce an output encoded speech signal, the input speech signal is encoded by a speech analyzer section into encoded speech signal data by means of an adaptive orthogonal transformation, and the encoded speech signal data is decoded into an output speech signal by a speech synthesis section.

Abstract: A method is proposed of processing packaging containing reactive residues. The packaging (13) is fed into a cold zone (2), cooled to a temperature at which the residues contained therein solidify and then shredded while in that cooled state (4). The shredded packaging material (13) is then divided into one fraction containing the reactive residues and at least one other fraction; the fraction containing the reactive residues is fed into a mixing zone (6) into which simultaneously an agent capable of reacting with the residues is also introduced, with a catalyst if appropriate, and the temperature in the mixing zone (6) is maintained at a level below the softening temperature of the residues and of the reactive agent. The resulting mixture of residue-containing fraction, reactive agent and (where appropriate) catalyst is conveyed to a reaction zone (7) at a temperature sufficiently high to allow a reaction and is there allowed to react.
