Abstract: The invention relates to a digital loop sharing telephone system and also to a digital telephone for connection into such a system. The loop (L) may be for a parallel telephone system or a party-line system. Each telephone instrument (10) is adapted to transmit data in an upstream direction on the loop that is towards an exchange of the system, which data may originate from the telephone instrument itself or a further telephone instrument downstream thereof. Each telephone instrument includes code detector circuitry (CD1, CD3) and logic circuitry (G2, G3) whereby if the telephone instrument is the first to change to an off-hook or active condition it "seizes" the loop for exclusive data transmission to the exchange. In the case of a parallel telephone system, any telephone instrument going off-hook can receive incoming data from the exchange but only the first telephone instrument to go off-hook can send data. In the case of a party-line system only the telephone which seizes the loop can receive data.

Abstract: Le produit à sécher est mis en contact avec un fluide de séchage caloporteur lorsqu'il parcourt la chambre de séchage. Le fluide de séchage humide est relâché dans l'atmosphère libre directement ou après récupération partielle de la chaleur; le produit séché libéré au degré désiré de son humidité est évacué vers un traitement ultérieur ou vers le lieu de sa consommation. Le fluide de séchage chaud et relativement sec qui sort d'une section de la chambre de séchage est recirculé vers l'entrée de la chambre de séchage. Le degré d'humidité du produit humide entrant dans la chambre de séchage et du produit séché sortant de cette chambre est mesuré et le signal différentiel analogique ainsi obtenu sert à la commande de la vitesse d'avancement du produit à sécher et éventuellement du chauffage du fluide de séchage. Le dispositif comprend une chambre de séchage munie d'une entrée pour le produit humide et d'une ouverture d'évacuation, un ventilateur à pression relié par un conduit d'entrée et éventuellement un ventilateur d'aspiration de fluide de séchage relié par un conduit d'évacuation. Un dispositif de chauffage du fluide de séchage est disposé avant ou après le ventilateur à pression. La chambre de séchage est divisée en une section de préchauffage et de séchage intensif, en une section de transport de l'humidité fixée et en une section de refroidissement. La section de transport de l'humidité fixée est reliée avec la section de préchauffage et de séchage intensif par un conduit de transfert et les signaux émis par les détecteurs d'humidité situés à l'entrée du produit humide et près de l'ouverture d'évacuation sont transmis à l'unité de commande de la grandeur du taux d'évacuation du produit séché.
