Title: Circuit de veille et dispositif de transmission de donnees muni d'un tel circuit
Inventor: STEERS MICHEL
IPC: H04B10/43
Filed: 1989-04-18
Abstract: Circuit de veille comprenant un thyristor et un circuit en boucle formé d'une self et d'un générateur d'énergie électrique produite par un événement lumineux. La boucle contrôle l'état de conduction - blocage du thyristor par le fait que la gâchette du thyristor est reliée à la borne du générateur dont la polarité bloque le thyristor lorsque le générateur est dans un état stationnaire d'éclairement. Le thyristor est débloqué par la rupture brusque de l'événement lumineux grâce à l'énergie restituée par la self. Ce circuit de veille est utilisé pour contrôler la mise en fonctionnement d'un badge alimenté par une source électrique autonome.

Title: Partial sealing device for electrodes of electric arc furnaces - comprising refractory ring placed on outer surface of vaulted roof axial to opening
Inventor: THIERRY BERNET
IPC: F27D99/00
Filed: 1992-06-17
Abstract: A device is claimed for partially sealing the electrodes (10) of an electric arc furnace incorporating a vaulted roof (2,6) provided with at least one opening (4) for the passage of an electrode (10). It consists of a refractory ring (20) placed on the outer surface (8) of the vaulted roof (2,6) axial to the opening (4). The refractory ring (20) can move with respect to the vaulted roof (2,6) and incorporates an annular cavity (22) for the injection of a gas and, on its periphery, a cooled metal sheathing (24). This cooled metal sheathing (24) is formed by a series of tubes (24a) connected to a cooling fluid feed circuit or may be in the form of a triangular section with its base resting on the furnace roof and incorporating an internal network for the circulation of cooling fluid. USE/ADVANTAGE - The device is used to partially seal the electrodes of an electric arc furnace, notably for steelmaking operations where the electrodes are mounted to move longitudinally through passages. It ensures partial sealing around the electrode whilst being of relatively simple structure tht is easy to put into service. Since the electrode does not come into direct contact with the walls of the opening in the furnace roof, is is subjected to less deteriroation or breakage. The injection of a neutral gas around the electrode considerably reduces the exchange of gases between the inside and outside of the furnace.
