Abstract: An electroacoustic device includes at least one precursor wave transducer. The at least one precursor wave transducer includes a piezoelectric substrate, and first and second electrodes of inverse polarity arranged on the substrate and configured to generate in the substrate a precursor ultrasonic surface wave which is unfocused. When a fluid medium is acoustically coupled with the electroacoustic device, the precursor ultrasonic surface wave propagates as a volume acoustic wave into the bulk of the fluid medium and focuses therein.

Abstract: The invention relates to a device and a method of applying a coating on a workpiece by electrodeposition. A vessel is provided that is suitable for filling with a bath of electrolyte, anode-forming conductor means being placed in the vessel and connected to a current generator, a cathode-forming workpiece mounted on the mandrel of a lathe, and guidance and movement means for guiding and moving the vessel relative to the lathe, the guidance and movement means enabling the workpiece to be immersed in full or in part in the bath of electrolyte.

Abstract: The invention relates to a device and a method of applying a coating on a workpiece by electrodeposition. In the method, a workpiece is mounted on the mandrel of a lathe. A vessel, connected to a current generator and containing a bath of electrolyte and a conductor forming an anode, is placed beneath the workpiece. All or part of the workpiece is immersed in the bath by moving the vessel into a first position. The workpiece is turned by the lathe so that the entire surface of the workpiece is immersed at least once in the bath while a material is electrodeposited on the workpiece. The vessel is moved into a second position to break contact between the workpiece and the bath of electrolyte.

Abstract: A monophasic method of achieving contraception in a human female comprising orally administering to the human female a composition comprising 1.5 mg of 17-beta-estradiol and 2.5 mg of nomegestrol acetate for 24 days followed by a hormone-free period of 4 days.

Abstract: The present invention relates to the area of chemotherapy and more especially to the development of new galenic forms for application to the skin. It relates more particularly to a topical hormonal composition with systemic action for the correction of progesterone deficiency in premenopausal women and for hormone replacement in menopausal women, characterized in that it contains, as the active principle, a progestogen derived from 19-nor progesterone, a vehicle permitting systemic passage of the said active principle chosen from the group comprising a solubilizing agent, an absorption promoter, a film-forming agent, a gelling agent or their mixtures, combined with or mixed with suitable excipients for production of a pharmaceutical form as a gel and/or a film.

Abstract: A method of achieving contraception in a woman which comprises administering orally to said woman an estroprogestative composition comprising nomegestrol acetate and an estrogen is provided.

Abstract: The invention concerns a method for focusing acoustic waves useful for obtaining an image of a field to be observed in a dissipative heterogeneous medium (2, 3) around which acoustic transducers (T1–Tn, T?1–T?m) forming an imaging network and a target network. The method consists in following a training step during which pulse responses from the medium are measured between each transducer (Ti) of the imaging network (5) and several transducers (Tj) of the target network (6); deducing therefrom reference signals to be emitted by the transducers of the imaging network to produce a focused acoustic pulse in each transducer of the target network, then cumulatively, in determining reference signals to be emitted to focus an acoustic pulse on predetermined points in the medium. Said reference signals are stored and used subsequently to generate an acoustic image of the medium.

Abstract: The present invention relates to the field of therapeutic chemistry and more especially to the realization of new galenic forms intended to be applied on the skin. More particularly it relates to a topical hormonal composition with a systemic effect for the hormonal treatment of the perimenopause and of the menopause as well as for the treatment of the ovarian hormonal deficiencies in women with amenorrhea, characterized in that it comprises, as active ingredients, a progestogen derived from 19-nor progesterone and estradiol or one of its derivatives, a vehicle which allows the systemic passage of said active ingredients, chosen from the group constituted by a solubilizing agent, an absorption promoting agent, a film-forming agent, a gelling agent and their mixtures, in combination or in a mixture with suitable excipients for the realization of a gelled and/or film-forming pharmaceutical form.

Abstract: A method of generating photons by sonoluminescence, from a gas bubble trapped in a liquid reservoir (2) by a standing ultrasound wave. An ultrasound impulse emitted by high-frequency transducers (T1–T8) is superposed on the standing wave, the high-frequency transducers being pre-focused onto the gas bubble and pre-synchronized with the light emissions from the gas bubble during an initial training stage in which said focusing and said synchronization are optimized.

Abstract: The invention concerns a method for focusing acoustic waves useful for obtaining an image of a field to be observed in a dissipative heterogeneous medium (2, 3) around which acoustic transducers (T1-Tn, T′1-T′m) forming an imaging network and a target network. The method consists in following a training step during which pulse responses from the medium are measured between each transducer (Ti) of the imaging network (5) and several transducers (Tj) of the target network (6); deducing therefrom reference signals to be emitted by the transducers of the imaging network to produce a focused acoustic pulse in each transducer of the target network, then cumulatively, in determining reference signals to be emitted to focus an acoustic pulse on predetermined points in the medium.
