Abstract: The invention concerns micro-organism strains, in particular of lactic acid bacteria, having a glycosylation modulating effect of intestinal cell surface. The invention also concerns a method for selecting micro-organism strains, in particular of lactic acid bacteria, which consists in measuring the average fluorescence intensity variation of HT29-MTX cells incubated in the presence of a lectin coupled with a fluorochrome after being in contact with the supernatant of the strain concerned. Said lactic acid bacteria strains can be used, optionally in the form of their active fraction, for preparing food compositions or medicines or food supplements, modulating glycosylation of glycoproteins of intestinal epithelial cells.

Abstract: The invention relates to a valve device including a built-in expansion valve and a flow selector. The valve function is provided by a blocker mounted so as to be inverted. The expansion valve is arranged laterally and communicates with a high-pressure chamber immediately downstream from the blocker and with a low-pressure chamber via a side passage. A device for mechanically controlling the blocker is provided in a chamber sealingly separated from the high-pressure chamber and from the low-pressure chamber. A flow selector in the form of a disc with a calibrated opening is provided in the low-pressure chamber, the disc engaging with a passage directly linked to the outlet of the device. The mechanical control device engages with a control pin of the disc.

Abstract: An alternating current motor may include a rotor configured to rotate about a longitudinal axis, the rotor comprising a diametrically magnetized permanent magnet. Furthermore, the alternating current motor may include stationary coils having a magnetic axis substantially perpendicular to the rotor's longitudinal axis, the stationary coils adapted to the rotor's outer periphery and being substantially coaxial with the rotor's longitudinal axis. In addition, the alternating current motor may include a stator adapted to the stationary coils' outer periphery and being substantially coaxial with the rotor's longitudinal axis, wherein the diametrically magnetized permanent magnet is configured to cause the rotor's oscillation angle to vary no more than 30% between the rotor's oscillation angle at a beginning value of a frequency range of an alternating current in the stationary coil and the rotor's oscillation angle at an ending value of the frequency range of the alternating current in the stationary coil.

Abstract: This axial mounting of the bottoms (5) of fan blades provides two levels of flexibility, and features rather low stiffness after using up a predetermined clearance (35) between two stop parts (32, 34), which then imposes a significant increase in stiffness; however significant energy was able to be absorbed through the elastic deformation of certain parts (7, 30) located between the blade and the disc (2), which enables the blade to withstand rather significant momentary forces, for example if a neighboring blade breaks and strikes it.

Abstract: A hydraulic apparatus is provided which comprises a liquid-pulse generator, and hydraulic motor connected to said generator by a flexible pipe. The motor is driven by liquid pulses provided by the generator via the pipe. The pulses form standing waves within the pipes with a certain wavelength. In order to insure an efficient energy transfer, the length of the pipe is an odd multiple of the quarter-wavelength.

Abstract: An electrically driven hand-held apparatus for body care, such as a toothbrush, operates by means of a rotating motor. An eccentric pin is driven by the motor and engages in a longitudinal slot defined by a fork which is secured to an instrument holder and in this manner sets the instrument holder supporting the treatment instrument such as the toothbrush in oscillatory motion about its longitudinal axis. In order to permit the oscillation amplitude to be adjusted without alteration of the oscillation frequency, the eccentric pin is fixed on a support inclined to its axis of rotation, the support being set in rotary motion by the motor shaft and the support being set in rotary motion by the motor shaft and the support being axially displaceable on its axis of rotation by means of an external operating knob. The effective eccentricity, that is to say the radial distance of the location of engagement in the longitudinal slot, of the eccentric pin from the axis of rotation of the support is thus variable.
