Filed: 1996-11-21
Granted: 2003-02-25
Abstract: A bidirectional disappearing plug member and plug assembly is capable of blocking pressurized fluid flow from opposing axial directions in a flowbore. In a preferred embodiment, the plug member, which blocks flow through the flowbore, may be readily and at least partially dissolved through the application of at least one pressurization and depressurization within a tubing string above the plug assembly. Construction of the plug assembly permits the plug member to be conveniently emplaced in a fluid-filled wellbore by permitting fluid flow around the plug member during the emplacement process. The plug member may then be secured within the plug assembly to block fluid flow from either axial direction. Operation of a plug rupture sleeve or mandrel, for at least partially dissolving the plug member, may be controlled by a ratchet assembly or linear indexing apparatus requiring multiple pressurizations and depressurizations before the plug member is exposed to wellbore fluids and thereby at least partially dissolved.

Abstract: The present invention is a method and apparatus for vacuuming toner waste from a toner sump in a xerographic printing machine. A xerographic module in the machine contains a photoconductor, charging devices, a cleaning unit and the toner sump.  When the toner sump approaches a full condition, the toner waste must be removed in order to prevent failure of the xerographic module seals. This is accomplished by removing the xerographic module from the machine, opening a sealed toner sump port and attaching a vacuum source to the toner sump port so that the toner waste can be removed with the vacuum source. A disposal adaptor tool sealingly engages the vacuum source to the toner sump at the toner sump port, allowing the toner to removed in a clean glove environment. Once the toner waste is removed from the toner sump, a new toner seal is placed over the toner sump port and the xerographic module is returned to the machine for further use.

Abstract: Cette invention se rapporte en général à des procédés de diagnostic et de traitement thérapeutique de la maladie de Friedreich. La maladie de Friedreich (FRDA) est une maladie dégénérative autosomique récessive qui touche le système nerveux central et périphérique et le coeur. Un gène, le gène X25, a été identifié dans la région critique du locus de FRDA sur le chromosome 9q13. Le gène code une protéine de 210 acides aminés, la frataxine, qui possède des homologues dans des espèces éloignées telles que C. elegans et la levure. Quelques patients atteints de FRDA se sont avérés présenter des mutations ponctuelles dans le gène X25, mais la grande majorité sont homozygotes sur un développement trinucléotidique GAA variable, instable dans le premier intron de X25. L'ARNm du gène mature X25 a été strictement et considérablement réduit chez des individus atteints de FRDA. Les porteurs et les individus risquant de développer FRDA peuvent être déterminés par les procédés de cette invention. De plus, les procédés de cette invention peuvent assurer un traitement à ces patients atteints de FRDA.
