Title: Marteau piqueur pneumatique
Inventor: LISTER WILLIAM
IPC: E21B4/14
Filed: 1987-10-26
Abstract: Un marteau piqueur pneumatique comprend une enveloppe (10), un carter supérieur (23) relié au tube extérieur d'une tige de forage à deux tubes, un tuyau d'amenée d'air (19) s'étendant depuis le carter supérieur (23) de façon coaxiale dans l'enveloppe et autour d'un tuyau de refoulement d'air (21) relié par son extrémité supérieure au tube intérieur de la tige de forage, son extrémité inférieur coulissant dans un passage d'air (38) qui traverse une mèche (31) dont la queue (32) coulisse dans un carter d'actionnement (33) au niveau de l'extrémité inférieure de l'enveloppe et est surmonté par une enclume (35), ainsi qu'un passage (43) comportant des conduits (39, 44) s'étendant à l'extérieur de la mèche (31). Un piston tubulaire (27), qui coulisse dans l'enveloppe (10) de façon coaxiale autour du tuyau de refoulement d'air (21), s'engage, lorsqu'il descend sur l'enclume (35), dans un tube (37) montant depuis le passage (38) à travers la mèche, la queue et l'enclume. Des chambres annulaires (11, 12, 13) sont formées à l'intérieur de l'enveloppe (10) et le passage axial du piston est divisé en des passages supérieur et inférieur (29, 30). Le piston (27) est pourvu d'orifices (45, 46, 47, 48) destinés à servir de soupape pour permettre un mouvement de va-et-vient, de sorte que le piston heurte l'enclume (35) lors de ses courses descendantes; mais, si l'enveloppe (10) est surélevée de façon à faire monter la mèche (31) par rapport à sa face d'attaque, l'enclume (35) et le piston (27) descendent, de sorte que le marteau se trouve en position d'équilibre et s'arrête automatiquement de fonctionner.

Title: Commande automatique de generateurs de vapeur a faible puissance
Inventor: SINGH GURDIP
IPC: G21D3/10
Filed: 1989-03-13
Abstract: Le niveau d'eau d'un générateur de vapeur, la température de l'eau d'alimentation, et la puissance du réacteur sont mesurés en continu et un signal de niveau (76), un signal de température (78), et un signal de puissance (80) en rapport avec ces mesures sont respectivement générés. A partir du signal de puissance et du signal de température est généré un signal d'écoulement théorique (84) correspondant au débit de l'eau d'alimentation qui donnerait au générateur de vapeur un niveau d'eau stable dans les conditions de stabilité du signal de puissance et du signal de température. Le signal de niveau est comparé à une valeur de consigne (54) et un signal d'erreur de niveau résultant (86) est généré. Le signal d'erreur de niveau est pondéré par un facteur de gain (88) qui est fonction du signal de température et permet d'obtenir un signal d'erreur de niveau pondéré (90). L'écoulement de l'eau d'alimentation par la soupape de dérivation est alors régulé en fonction du signal d'écoulement théorique (84') et du signal d'erreur de niveau pondéré. Dans un mode préféré de réalisation de l'invention, la transition entre la commande à faible puissance au moyen de la soupape de dérivation et la commande à puissance élevée au moyen de la soupape principale d'eau d'alimentation s'effectue par la production d'un signal de position de soupape principale (118), et par la production d'un signal de validation (124) lorsque le signal de puissance se situe dans une plage de puissance de transition désirée. Lorsque la puissance se situe dans la plage de transition, l'écoulement de l'eau d'alimentation par la soupape de dérivation est diminué ou augmenté progressivement en fonction du signal d'écoulement théorique, du signal d'erreur de niveau pondéré, et du signal de position de la soupape principale, à mesure que le flux principal d'eau d'alimentation augmente ou diminue.
