Abstract: PROCESS FOR THE TREATMENT OF SULFUR CONTAINING GASES     ABSTRACT     Process of treating sulfur containing gas streams by the Claus reaction in which a recycle stream containing a reactive component is employed in a negative feedback mode to maintain the sulfur producing Claus reaction at approximately equilibrium conditions.  The feedstream may contain hydrogen sulfide or sulfur dioxide in a minor amount in an inert gas background.  In one embodiment the feedstream to the reaction zone contains a stoichiometrically excess amount of sulfur dioxide for the Claus reaction.  Effluent from the reaction zone is passed to a hydrogenation zone where the sulfur dioxide is converted to hydrogen sulfide.          Hydrogen sulfide is extracted from the hydrogenation zone effluent and recycled to the Claus reaction zone.  In another embodiment the feedsteam may contain a stoichiometrically excess amount of hydrogen sulfide.  Effluent from the reaction zone is treated to produce a hydrogen sulfide containing recycle stream which is then subject to at least partial oxidation to produce a converted stream containing sulfur dioxide.  The converted stream is recycled to the reaction zone. The invention may be employed in the high pressure processing of hydrocarbon gases containing sulfur.

Abstract: ABSTRACT OF THE DISCLOSURE    A tool  to dewire  a bale  of dry  pulp, waste  paper or the like. The tool grabs the wire, cuts it and  retains the cut wire.          The same sequence of operation is repeated for other wires.   The tool then coils the cut wires and discharges the coils  as waste.          The tool comprises a support casing in which is rotatably mounted a vertical cylindrical tube.   This  tube includes  at its bottom end a  pair of  opposite slots  having a lower portion spiralling for about a quarter of a turn, and an upper portion which extends longitudinally  of  the  tube.    A  grabber  arm,  operated by a hydraulic cylinders, is mounted  within the  tube for up-and-down movement.    Wire  bending  elements  and a cutter blade are also mounted  within  the  tube.    In  operation  the  tool  tube  is positioned over  a selected  wire and  applied on  the bale.  The tube is rotated about one-quarter of a turn  to pick  up the wire in its spiral slots and raise the wire off the bale.  The grabber arm then hooks the wire and pulls the same up.  The wire is bent, is cut  and its  bent end is retained in the tube.  Several wires can be  cut and  retained in  the same  manner. The  tube is then rotated several  turns, to  be used  as a  mandrel in association with a coil-forming shoe, so as to wind  the wires  into compact coil.    Then  the  shoe  extracts  the  coil from  the tube for discharge into a bin.

Title: Gaswell dehydrate valve
Inventor: KLATT WAYNE
IPC: E21B43/12
Filed: 1988-06-16
Granted: 1992-06-02
Abstract: ABSTRACT   A threaded sleeve valve to facilitate the removal of water from gas wells having two or more gas productive zones disposed vertically along their bore. The valve is adapted to form a connection between a segregation packer and a well tubing string.  In use, the valve and the segregation packer are sunk in the well to a position intermediate an upper gas productive zone and a lower gas productive zone.  During normal gas production, the valve is closed and gas is collected from both zones, the gas from the lower zone passing through a vertical passage defined by the valve and continuous with the interior of the well tubing.  Incidental water accumulated above the segregation packer can be removed by opening the valve and using the gas pressure of the lower productive zone to force the accumulated water upwards to the wellhead and out of the well.  Once the well bore has been purged of incidental water, the valve is re-closed and normal production resumes.  The valve is operated from the surface by turning the well tubing string in the required direction.

Granted: 1992-04-07
Abstract: Abstract of the Disclosure:       In an arrangement which is for use in an electronic circuit controllably put into operation by a battery (20) and which is for indicating a consumption status of the battery, a measuring circuit (22) measures a total time interval of operation of the electronic circuit.  A processing circuit (21, 27) processes the total time interval into a calculated status for the battery.  An indicator (32) indicates the consumption status based on the calculated status.  The processing circuit may comprise a memory (21) for memorizing various current rates which are used in the electronic circuit and on which an arithmetic circuit (27) calculates the calculated status.  Alternatively, first and second measuring circuits (25, 26) may be used with first and second current rates memorized in the memory for the first and the second measuring circuits.          Instead of the measuring circuits, a summing circuit may be supplied with a succession of the current rates repeatedly read out of the memory to sum up a total amount of consumed current consumed by the electric circuit.  As a further alternative, a counter counts down to obtain the total time interval in response to a pulse sequence of a pulse repetition period variable in proportion to a varying level of electric current supplied from the battery to the electronic circuit.

Abstract: Le dispositif d'asservissement d'un signal en fréquence et en phase à celle d'un signal imposé, est du type à boucle de verrouillage de phase. Il comporte un modulateur mélangeant un signal dont la fréquence est proportionnelle à celle d'un signal issu d'un oscillateur Vco et un autre signal dont la fréquence est proportionnelle à celle d'un signal de référence issu d'un oscillateur. La composante de basse fréquence du signal combiné (isolée par un intégrateur) est appliquée en permanence à l'oscillateur sur une entrée à sensibilité relativement faible, pour les corrections fines, et à une boucle rapide comportant un élément de mémorisation et un amplificateur, par l'intermédiaire d'un commutateur commandé par un comparateur à fenêtre. La boucle rapide est connectée à une entrée à sensibilité plus élevée. La boucle rapide n'agit que durant la période de calage, pour amener la tension de commande de l'oscillateur au voisinage de la tension optimale, l'optimisation étant effectuée par la boucle permanente. La présente invention peut être appliquée au verrouillage rapide de la fréquence d'émission d'un émetteur FM par exemple où encore à la récupération d'un signal d'horloge rythmant une transmission de signal.
