Abstract: Telecommunication line circuit includes two line driver feedback amplifier circuits (OA1, OA2) connected to first and second conductors of a telecommunication line (L) and fed via a gating circuit (PC) by a common variable line length dependent (DC) supply voltage provided by a line loop current control circuit sensing the voltage drop across the line loop resistors (RLI, RL2) and thus sensing the line length. Each line driver amplifier (OA1, OA2) circuit is a differential amplifier circuit including a differential-to-single-ended stage (S1), an intermediate stage (S2) and an output stage (S3). The differential-to-single-ended stage (S1) has a low input impedance and includes a slew rate circuit with two cross-coupled cascode circuits (Q29-Q32) providing a high output impedance. The output stage (S3) is a class B emitter follower stage including a current deviation circuit (38, 39) which decreases the power consumption when the line loop is open. In this case the gating circuit (PC) only connects the supply voltage (D+, D-) to the output stage.

Abstract: The machine for forming cylindrical bales of hay or stray has a fixed housing (2) with a hinged door (6). The bales are formed by a system of belts and pulley, with a pressure being exerted on the bale by a swinging arm (14).

Le dispositif de contact provoque la reconfiguration de toute partie affaissée ou décalée du tube et permet au tube (31) d'avoir un axe central longitudinal qui est une ligne droite s'étendant entre les supports d'un tour qui maintiennent les extrémités du tube. Le dispositif de contact (101, 102) peut également être utilisé pour donner au tube une configuration prédéterminée sur sa longueur. La position du dispositif de contact par rapport à la température maximum à l'intérieur de la zone mobile de chaleur pour chaque incrément de longueur du tube de verre permet de modifier la forme du tube et de maintenir cette forme.
