Abstract: Il est connu que, pour établir un réseau de radiodiffusion interactif, il faut non seulement une voie de transmission entre l'émetteur et le récepteur mais également une voie de transmission entre le récepteur et l'émetteur. Le nouveau procédé de création d'une voie de retour de données du récepteur à l'émetteur est mis en oeuvre dans un réseau à fréquence commune et implique l'utilisation d'un procédé de transmission conforme à la norme DAB. A chaque récepteur ou utilisateur est alloué un élément d'identification qui est transmis sur des fréquences réservées à cet effet pour demander une capacité de transmission dans la voie de retour de données. Un ordinateur affecte alors une capacité de transmission au récepteur. A des fins de synchronisation de l'unité d'émission du récepteur, les signaux reçus dans la voie d'aller sont évalués au moyen des symboles de synchronisation qu'ils contiennent. Le nouveau procédé peut être mis en oeuvre dans tous les réseaux à fréquence commune dans lesquels la transmission de données se fait conformément à la norme DAB, et il permet une synchronisation particulièrement économique dans le récepteur.

Title: Recycling process of a cross-linked polymeric material, in particular from electric cable coating materials
Inventor: PRIGENT MADELEINE
IPC: B29C48/06
Filed: 1998-08-11
Granted: 2005-08-09
Abstract: A process for dereticulating a cross-linked polymeric material, such as cross-linked polyethylene from scraps of electric cable coatings or from unused cable coatings through a mechanical mixing cycle, wherein the cross-linked material is subjected to a specific power per mass unit such as to induce shear stresses in the material itself and temperatures higher than pre-established minimum levels. At the end of this cycle the material goes back to a thermoplastic state that may be substantially regarded as thermoplastic; then, following granulation, cooling, drying and sacking, the material will be ready for re-use, either alone or mixed with virgin polymers, according to usual operating technologies for thermoplastic materials.      Eventually, the mechanical mixing cycle may be preceeded by a preliminary crushing cycle of the cross-linked polymeric materials to be treated.  Preferably, the mixing cycle is carried out in a twin-screw extruder with special screw and temperature profiles.

Granted: 2003-09-09
Abstract: In the embodiments of the simplified ink jet head described in the specification, a carbon body is formed with ink passages, such as internal passages (19, 21, 25) extending through a carbon plate (26), pressure chambers (2) on one side of a carbon plate (26), flow-through passages (24) on the other side of the same plate and ink supply passages (19, 25), and a piezoelectric plate (23) is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive.  The piezoelectric plate (23) may have a conductive coating on one side which is photo-etched to produce an electrode pattern corresponding to the pattern of the pressure chambers in the carbon plate.  An orifice plate (13) may have specially profiled orifice openings (12) to assure axial projection of drops and may be affixed by a thin layer of epoxy adhesive to a carbon plate (26) having orifice passages (21) supplying ink from the pressure chambers (20) to the orifices (12).  Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate (23) and, to assure grounding of the piezoelectric plate, a conductive epoxy adhesive may be used to bond the piezoelectric plate to the carbon plate.  Moreover, since the carbon plate is porous, it can provide a communication path (76) between a vacuum source (77) and an air-permeable, ink-impermeable layer (75) on the ink passages to remove dissolved air from the ink in the passages.  In one alternative embodiment, an ink jet head assembly contains two separate carbon pressure chamber plates, a carbon manifold plate and a carbon collar to retain the carbon plates in an assembly.
