Abstract: A speaker system such as a sound bar assembly having a plurality of speaker units and improved sound quality is provided. Opposing mating portions of front and back panels of the assembly or system are fused or welded together to form outer boundary and interior joints where the front and back panels are welded together. The front and back panels are spaced apart at their first and second ends to define first and second speaker compartments, respectively, separated by a central compartment. A speaker unit is positioned in each of the speaker compartments. The speaker compartments are acoustically isolated from one another by the interior joints to improve the sound quality.

Abstract: A method of determining conditions for machining a part so as to avoid vibration appearing during the machining. A machining stage is simulated by provisionally setting parameters of a function for modulating cutting speed, by deducing a corresponding surface state, by modifying parameters iteratively with the machining stage being simulated each time until the surface state reaches an acceptable value, and by performing the machining stage by causing the cutting speed to vary in application of the corresponding modulation function.

Abstract: The invention relates to a tool for machining hard materials such as metal-matrix or organic-matrix composite materials, comprising a cylindrical sonotrode (22) connected, along the axis (A) of said cylinder, to an assembly vibrating at a predetermined ultrasonic frequency and rotated about said axis, and at least one nozzle (3), on the surface to be machined and at the terminal end (24) of the sonotrode, for ejecting a liquid in which abrasive particles are suspended, said particles being vibrated at said ultrasonic frequency by the sonotrode so as to form a drilling head along the axis (A) of the cylinder, characterized in that the circumference (23) of the sonotrode is covered with particles of a so-called superhard material in order to form a milling head capable of moving in a plane that is substantially perpendicular to said vibratory axis (A).

Abstract: The abrasion machining method according to the invention, for abrading a part that cannot be machined by conventional means, comprises the following steps: a pin is placed at a certain distance from the part to be machined, so that there is no contact between the part and the pin; the pin is driven so as to rotate; an abrasive liquid is injected between the rotating pin and the part in order to abrade the latter; and the pin is moved translationally along the part. Thanks to the method, the part may be machined precisely and reproducibly.

Abstract: An anti-idiotypic monoclonal antibody that is specific against the N-glycolyl residues of gangliosides, particularly those expressed by cancer cells. The monoclonal antibody is useful as an immunomodulator for cancer treatment. Specifically, the anti-Id monoclonal antibody of the present invention is capable of inducing a predominant anti-idiotypic response in xenogeneic models. The anti-idiotypic monoclonal antibody also exerts a protective effect against malignant tumors in animals.
