Filed: 2014-07-25
Abstract: L'invention concerne un système d'outil qui est adapté pour être utilisé avec une machine-outil, notamment portatif, qui comporte un dispositif d'entraînement mobile, notamment oscillant, sur un axe d'entraînement. Le système d'outil comprend un dispositif de raccordement au moyen duquel il peut être fixé à une machine-outil de telle sorte que l'axe d'entraînement de celle-ci et un axe de rotation de l'outil coïncident sensiblement. Pour absorber une force d'entraînement, le dispositif de raccordement comporte au moins deux zones de surface d'entraînement qui sont disposées à distance de cet axe de rotation de l'outil et qui possèdent chacune une pluralité de points de surface. Les plans tangents à ces points de surface sont alors inclinés par rapport à un plan axial qui inclut l'axe de rotation de l'outil. En outre, ces plans tangents sont inclinés par rapport à un plan radial qui s'étend perpendiculairement à l'axe de rotation de l'outil. Le couple appliqué par la machine-outil au système d'outil par le biais du dispositif d'entraînement est ainsi absorbé de manière fiable.

Filed: 2016-02-25
Abstract: A bioreactor has a biofilm supporting bed with at least two types of media. An upper media is relatively porous, preferably porous enough to admit particles of a lower media. In use, wastewater flows downwards through the bed. Soluble nitrogen is reduced in the upper media and converted into nitrogen gas. Nitrogen gas bubbles rise through the upper media and escape from the bed. Selenium is reduced in the lower media and converted into elemental selenium. The elemental selenium is released periodically by backwashing the bed, which may cause fluidization or other expansion of the lower media into the upper media.

Abstract: Fracture imaging modules having one or more 3-component sensors, are incorporated into a tool comprising two or more of the modules for detecting microseismic events in a formation from the same wellbore as is being stimulated.  The modules are locked together in a compact mode to permit injection into the wellbore through a conventional lubricator which has a fixed length. Once injected into the wellbore, the modules are spaced from one another in an extended mode to form an axially spaced sensor array which increases the measurement window in the wellbore compared to sensor arrays conventionally injected through a fixed length lubricator Following the operation, the modules are actuated to return to the compact mode for pulling out of the hole through the lubricator.
