A support stand is operable to receive the downhole sampling chamber. A magnetic field generator is operably associated with the downhole sampling chamber such that when the magnetic field generator generates a magnetic field, the mixing element moves through the formation fluid sample responsive to the magnetic field, thereby mixing the formation fluid sample.

Abstract: A subsea safety system (50) for use during a well treatment operation. The subsea safety system (50) includes a tubular string having an inner flow passage (112). At least one valve assembly (116, 134) is positioned within the tubular string. The valve assembly (116, 134) is operable between open and closed positioned to selectively permit and prevent fluid flow therethrough. A frangible liner (134) is disposed within the valve assembly (116, 134). The frangible liner (134) has a close fitting but not fluid tight relationship with the valve assembly (116, 134). The frangible liner (134) is operable to protect the valve assembly (116, 134) from particle flow during the well treatment operation. In addition, the frangible liner (134) is operable to shatter responsive to closure of the valve assembly (116, 134), thereby allowing full operation of the valve assembly (116, 134).

Abstract: A system for the laser beam deflection for optical measuring systems includes an optical element for the deflection of an incident laser beam and a driving unit for generating a rotational movement between the optical element and the incident laser beam in order to deflect the laser beam in different successive directions. The optical element includes at least two segments for the deflection of the incident laser beam by one fixed deflection angle respectively. During the rotational movement, the laser beam successively impinges on the different segments.

In the case of a method for the laser beam deflection, a laser beam impinging in an offset manner with respect to the axis of rotation is deflected during a time period by each segment into precisely one defined direction.
