Title: Tool chuck
Inventor: NAKAMURA DAIJIRO
IPC: B23B31/173
Filed: 1990-10-18
Granted: 1996-07-09
Abstract: A tool chuck according to this invention com-prises a locking device disposed between a chuck body and chuck claws slidable by screw feeding.  The lock-ing device presses and locks to the chuck body by a reaction force occurring when the chuck claws clamp a tool.  The tool chuck further comprises a torque amplifying device disposed between the locking device and a control ring rotatably mounted on the chuck body.  When the locking device is locked to the chuck body, the torque amplifying device reduces rotation of the control ring to output an amplified torque to a screw ring which screw-feeds the chuck claws.  The chuck claws are slidable fast until the chuck claws clamp a tool inserted in position to realize a quick clamping action.  When the chuck claws contact and hold the tool, the chuck claws are slidable with an increased torque, thereby holding the tool with a strong clamping force.

Patent CA-2049355-C (CA)
Title: Drill stem test tools
Inventor: BUCHANAN ROBERT DONALD
IPC: E21B34/10
Filed: 1990-03-27
Granted: 1997-12-02
Abstract: Once a new oil well has been drilled and cased, a test string is set in place for the purpose of evaluating the production potential of the chosen formation. One way of controlling the operation of the various tools included in the downhole test string, including the opening and closing of the downhole valve itself, is by changes in the pressure differential between the tubing and the annular space which surrounds it in the well, but this requires the provision and maintenance of a fixed "reference" pressure within the tool, and a convenient such pressure is the hydrostatic (annulus) pressure experienced by the string after it has been lowered down the well bore and set into the packer. The invention proposes that reference pressure within the test string be trapped by a novel mechanism wherein a valve (4) drivable into a closed position by a first piston (3) open (at 5) to annulus pressure first defines, and then defines and closes, the open-to-tubing-pressure entrance (6) to a passageway (30, 19) leading to a reference-gas-containing chamber (22) via a second piston (20) therewithin. The invention also proposes a new mechanism by which compensation can be made for the effect of downhole temperature changes on the gas in a reference pressure chamber, in which mechanism there is a hydraulic-liquid-containing chamber (27) which is connected at one end, via a piston (25) thereat, to a vent (24) to annulus and at the other end to two "one-way" passageways (28,29) linking it to the reference-gas-containing chamber (22) via a chamber-contained second piston (23).

Filed: 1991-12-27
Granted: 1996-12-10
Abstract: The present invention provides a water piping system wherein when a predetermined time elapses after the flow of the water in a hose has stopped, the water is drawn out of the hose, thereby preventing proliferation of various bacteria in the water standing stagnant in the hose and when the temperature of the water drops, the water is completely drawn out of the hose, thereby preventing a water pipe from rupturing or cracking in the wintertime.           The water pipe including a reducing valve which is at a position higher than a waterstop valve is connected with a hose through a first electromagnetic valve. The required number of second electromagnetic valves are located intermediate on the hose. When a predetermined time elapses after the flow of the water through the hose has stopped, the first valve is temporality closed while the second valves are opened. When a water-temperature sensor incorporated into one of the second valves senses that the temperature of the water has dropped to a predetermined lever, the first valve is closed while the second valves are put open.

Abstract: On décrit un système de tomographie à plusieurs trajets qui permet de visionner en séquence différentes régions d'un objet (14) sans qu'un mouvement mécanique de l'objet soit requis. L'objet est placé entre une source de rayons-X rotative (32) et un détecteur rotatif synchronisé (16). Un plan focal (74) à l'intérieur de l'objet est représenté par image sur le détecteur (16) de sorte qu'une image en coupe transversale de l'objet est produite. La source de rayons-X est généralement produite par la déflexion d'un faisceau d'électrons (30) sur une anode cible à transmission plane (24). L'anode cible (24) émet un rayonnement de rayons-X (34) à l'endroit opposé de celui où les électrons sont incidents sur la cible. Le faisceau d'électrons est produit par un canon à électrons (18) qui comprend des bobines de déflexion X et Y (22) servant à déflechir le faisceau d'électrons (30) vers des directions X et Y correspondantes. Des signaux de tension de déflexion (60, 62) sont appliqués aux bobines de déflexion X et Y (22) et font tourner la source de rayons-X sur un trajet circulaire. Une tension continue appliquée à la bobine de déflexion X (22) provoquera le déplacement du trajet circulaire, tracé par la source de rayons-X (32) dans la direction X et par une distance proportionnelle à l'intensité de la tension continue. Ceci, à son tour, amènera un différent champ de vision (70, 72), qui est déplacé dans la direction X par rapport à la région précédemment mise en image, à être représenté par image dans le même plan focal (74) de l'objet. Une tension continue appliquée à la bobine de déflexion Y (22) déplacera le trajet circulaire tracé par la source de rayons-X (32) dans la direction Y par une distance proportionnelle à l'intensité de la tension continue. Ceci à son tour amènera un champ de vision différent (70, 77), qui est déplacé dans la direction Y par rapport à la région précédemment mise en images, à être représenté par image dans le même plan focal (74) de l'objet (14). Des changements identiques dans les intensités des signaux de tension appliqués aux bobines de déflexion X et Y changeront le rayon du trajet de la source de rayons-X, ce qui résulte en un changement dans le niveau Z du plan focal représenté par image (74).
