Fluid-powered linear motor with rotary pistons and motion rectifier and synthetic diamond bearing assemblies
A fluid-powered linear motor with rotary pistons is disclosed. An application is for a downhole motor but it could be used in other applications. Rotational pistons provide increased torque generation as the torque generated is proportional to motor length. Since downhole drills are long (generally up to a maximum length of 30 ft.), a high-torque motor can be produced using this method. A pressurized fluid is used to drive the piston assemblies to produce bit shaft power. This concept employs rotary pistons and a mechanical rectifier to convert the rotational reciprocation produced by a reciprocating rotational piston into continuous rotary motion. Integration of synthetic diamond bearing assemblies into the motor allows for reduced friction and abrasive drilling fluid compatibility. |

Seal condition monitoring
A method of seal condition monitoring may determine the state of the annular seal, the state of one or more sealing elements, take actions to maintain the annular seal as one or more sealing elements transition from new to worn, and provide advance notice of the impending failure of one or more sealing elements so as to avoid a catastrophic annular seal failure while the marine riser is pressurized. Advantageously, operations may be conducted proactively rather than reactively, and one or more sealing elements may be replaced well in advance of failure, but potentially later than a conventional maintenance schedule would dictate. The one or more failing sealing elements may be proactively replaced without depressurizing the marine riser, prior to seal failure or replacement may be planned well in advance and coordinated with other rig operations to improve efficiency and maintain the safety of the drilling rig and personnel. |

Method for the manufacture of highly purified 68Ge material for radiopharmaceutical purposes
A method for the manufacture of highly purified 68Ge material for radiopharmaceutical purposes. The invention particularly concerns the production of 68Ge-API (API=Active Pharmaceutical Ingredient) solution complying with the Guidelines for good manufacturing practices (GMP). Starting material for the method of the present invention can be a 68Ge stock solution of commercial or other origin as raw material. Such 68Ge containing raw solutions are purified from potential metal and organic impurities originating from production processes. The radiochemical method disclosed is based on a twofold separation of 68Ge from organic and metallic impurities with two different adsorbent materials. During the first separation phase 68Ge is purified from both organic and metallic impurities by adsorption in germanium tetrachloride form, after which hydrolyzed 68Ge is purified from remaining metallic impurities by cation exchange. The final 68Ge-API-product e.g. fulfills the regulatory requirements for specifications of the GMP production of 68Ge/68Ga generators. |
