Title: Polyamide-imide solutions and their preparation process
IPC: C08G18/08
Filed: 1989-09-14
Granted: 1993-06-09
Abstract: The present invention relates to spinnable and mouldable polyamide-imide solutions as well as the process for their preparation. They contain 4 to 35% of a polyamide-imide having a polydispersity index</=2.1 in a solvent mixture containing 45-100% by weight of DMEU and 0-55% of an aprotic polar solvent. They are obtained by the reaction, in dimethylethyleneurea of pH</=7 as polycondensation solvent, of a diisocyanate, an aromatic acid anhydride, optionally an alkali or alkaline earth dicarboxybenzene sulphonate and optionally another aromatic dicarboxylic acid, the polyamide-imide concentration therefore being from 4 to 35%, then by dilution in a polar solvent at a temperature of between 120 DEG  and 200 DEG  C. The solutions thus obtained are limpid at ambient temperature, capable of being stored and have an improved color.

Abstract: The present invention relates to an automatic gain control circuit (AGC) in a receiver for a digital radio telephone. Most of the total gain control of the received signal is accomplished in the base band frequency sections, in the I and Q branches whereof the signal amplification is controlled step by step, and only a minor part of the total gain control is performed in the RF stage. High amplification steps are formed by means of amplifiers (9a, 10a, 11a, 12a; 9b, 10b, 11b, 12b), of which the desired amplifier is activated by means of a digitally controlled (A, B) multiplexer (13a, 13b), and low amplification steps are formed by means of a resistance attenuator (14a, 14b), in which a signal of desired level is selected by means of a digitally controlled (C, D, E) multiplexer (15a, 15b). In addition, the RF amplifier (2) has two amplification levels, of which the desired amplification is selected by means of a digital control (F). By means of different digital control combinations (A, B, C, D, E, F) the entire gain control range required of the receiver can be covered.
