摘要： A stabilizing fin assembly for use with a watercraft includes a mounting structure, a stabilizing fin structure, and a releasable securement structure. The mounting structure is fixedly attached to a side portion of a hull of a watercraft. The stabilizing fin structure is removably mounted to the mounting structure. When the mounting structure is fixedly attached to the hull, the stabilizing fin structure is disposed externally of the hull and adjacent the side portion of the hull in an operative position wherein at least a portion of the stabilizing fin structure extends into a body of water while the watercraft is in a normal operative position. The releasable securement structure is disposed in a releasably secured position on the hull. The stabilizing fin structure facilitates removal and replacement of the stabilizing fin structure without requiring access to the interior of the watercraft.

摘要： The apparatus (10) is used for determining the consistency index (k) and the power law index (n) of a Newtonian fluid or non-Newtonian power law fluid. A method is also disclosed. Accordingly, the fluid flows in a laminar manner through a first (12) and a second static mixer (14) successively connected together by means of an intermediary pipe (18). A first pressure differential (&Dgr;P1) corresponding to a pressure drop of the fluid through the first static mixer (12) is measured. Similarly, a second pressure differential (&Dgr;P2) corresponding to a pressure drop of the fluid through the second static mixer (14) is measured. Finally, the consistency index (k) and the power law index (n) are calculated using the Metzner and Otto concept generalized to static mixers. The apparent viscosity may also be calculated. This invention may be mounted directly on a main supply pipe (16) and allows the rheological properties of the fluid to be known in real time. It also improves the mixing of the fluid and maintains its homogeneity.

摘要： A vectorial magnetometer (1), measures the components of a magnetic field in three directions (Oxyz) using a scalar magnetometer (2). The field is periodically modulated in each of the directions by generators (Gx, Gy, Gz) which have a specific frequency for each direction and that power coils (Ex, Ey, Ez). Synchronous demodulation of the of the output signal of the scalar magnetometer (2) for each of the three frequencies permits the relative continuous component of each axis to be found. The vectorial magnetometer (1) is characterized in that it has means (Dx D′x, Dy D′y, Dz D′z) that can carry out a double demodulation for phase and quadrature for each of the frequencies and processing means (70) that use the continuous component modules for phase and quadrature to calculate a transfer function of the scalar magnetometer at the frequency in question, and to apply this function to the correction of the components.
