Abstract: An Automatic Soundtrack Generator permits merger of a sound track that is independent of the external sound source, while either recording or playing a video sequence. The Automatic Soundtrack Generator integrates in a video recorder or player a module that generates music or other sounds which either can be mixed with the originally recorded sound (sound mixing), or can replace the originally recorded sound (sound dubbing). This sound mixing or dubbing can be performed either at video/audio record time or at play back time.

Abstract: This invention relates to an optical interconnection system in a microelectronic circuit made on an SOI substrate (30), in other words a substrate with a silicon film (13, 33, 53) supported by a layer of electrically insulating material (32), the microelectronic circuit comprising at least one function block to be connected made in the silicon film. The system comprises at least one optical microguide composed of a strip (40) delimited in the silicon film by lateral confinement areas (41, 42) to connect the function block.

Abstract: Systems and methods for creating, modifying, interacting with and playing music are provided, particularly systems and methods employing a top-down process, where the user is provided with a musical composition that may be modified and interacted with and played and/or stored (for later play). The system preferably is provided in a handheld form factor, and a graphical display is provided to display status information, graphical representations of musical lanes or components which preferably vary in shape as musical parameters and the like are changed for particular instruments or musical components such as a microphone input or audio samples.

Abstract: An apparatus for manufacturing a hollow turbomachine blade made from a titanium alloy of the TA6V type includes a hot twisting step in which an element of the blade is twisted progressively at a temperature above 700° C. by a plurality of bars which are rotated about the twist axis and act on collars previously fixed to the element, the distribution and number of collars being determined according to the desired twist to be imparted and such as to obtain a linear twist development between each collar.

Abstract: A process for manufacturing a hollow turbomachine blade made from a type TA6V titanium alloy includes a hot forming step in which an element of the blade is isothermally shaped in a press at a temperature between 700° C. and 940° C. under the action of at least two stamps and a holding-clamp which press the blade element on a shaping die, while ensuring a controlled deformation rate so as to obtain a lengthening of the fibers, that is to say the elongation of the different fibers of the element, with a controlled distribution on both sides of the central fiber. A multiple-action furnace-press designed for carrying out the process is also described.

Abstract: The process comprises introducing the tubes in the form of horizontal layers (the generator can be positioned horizontally for this purpose), installing anti-vibratory bars on the layers, placing weights on the bars and checking the clearances between the tubes and the bars, so that the tubes falling outside the accepted tolerances can be replaced. This is followed by the installation of the layer of tubes immediately above it. This procedure is repeated until all the layers have been installed. The invention is used in the steam generators of nuclear power stations.

Abstract: A method of continuous welding of a series of tubes to a tube sheet, in which the torch current is decreased to produce partial fading of the arc after completion of the first welding bead, and the torch is then moved to a starting position on a second contour to be welded. A stationary preheat is then effected, and a second weld bead is made by following the second contour to be welded. The process continues until the last bead has been made, whereupon the arc is switched off.
