Title: Improvements introduced into patent of invention No 9200325, by improvements in the process for manufacturing service desks and their parts
Inventor: CUBERO PINTEL JOSE ANTONIO
IPC: H05K3/34
Filed: 1997-05-09
Abstract: Improvements introduced into patent of invention No 9200325 by improvements in the processors for manufacturing service desks and their parts. In order to achieve an improvement in the soldering, especially for the through components, soldered to both faces of a printed circuit, soldering processes with different characteristics are stipulated, at each one of the ends of the components, in such a way that the two soldering operations do not substantially affect each other. In order to avoid the consequences, a solution has been developed consisting in using soldering alloys with different melting points for each of the faces of the component, with the object of avoiding re-melting during the second soldering operation, which continues to be carried out with the lead/tin alloy whose melting point is 183 degree C.

IPC: H01Q15/00
Filed: 1999-06-07
Abstract: The invention relates to a printed circuit technology multilayer planar reflector reflecting the electromagnetic field from a feed (110) forming a collimated or conformal beam by performing adjustments in the reflection coefficient phases.

Title: Formulations medicamenteuses a enrobage enterique et leur fabrication
Inventor: GUO HONGXIA
IPC: A61K9/22
Filed: 2001-12-17
Abstract: La présente invention concerne des formulations médicamenteuses pour administration entérique comprenant une pastille enrobée dans un film avec une dispersion entérique aqueuse de latex ou de pseudolatex, ou bien une solution de polymères sensibles au pH. Ces granules sphériques (pastilles) à enrobage entérique sont de préférence préparées à partir d'un mélange en poudre granuleuse humide de cellulose microcristalline et d'amylopectine tirée de l'amidon de maïs. La pastille qui renferme de l'amylopectine comme co-excipient présente une perméabilité prématurée extrêmement faible, même à un agent actif fortement hydrosoluble dans le milieu acide du suc gastrique simulé. Une libération sure et efficace du médicament se produit dans l'environnement à pH élevé du fluide intestinal simulé. Utilisée comme matériau de sous-couche dans les pastilles à enrobage entérique, l'amylopectine améliore également les propriétés  de résistance aux acides desdites pastilles dans le suc gastrique simulé.

Abstract: Method and device in multi-cylinder dryers of a paper machine, which said dryers comprise two lines of drying cylinders (10, 11), in whose connection twin-wire draw is applied, by means of whose drying wires (F1, F2) a closed draw is obtained in the transfer of the paper web (W) from one cylinder line onto the other. In the closed draw, the guide rolls (12/13) of the drying wires (F1/F2) are placed at the proximity of the run of the other wire (F2/F1) on which the drying wire runs from its drying cylinder (11/10) to its guide roll (13/12). For the purpose of ventilation of the pockets (T1, T2) defined by the drying wires (F1, F2) and by the free faces of the drying cylinders (10, 11), an air jet or air jets (S1) are blown against the drying wires (F1, F2) within the area in which the drying wire (F1/F2) contacts the said guide roll (13/12) of the other drying wire (F2/F1). As the said blowings, drying air is passed through a widening wedge space (N) defined by the said drying wire (F1/F2) and by the guide roll (13/12) into the said pocket (T2/T1) so as to ventilate the pocket. The air jet (S1) or jets are preferably directed perpendicularly to the face of the drying wire (F1/F2) that is opposite relative the web (W) at a location facing the guide roll (13/12) of the other drying wire (F2/F1).

Filed: 1995-11-28
Abstract: L'invention se rapporte à un récepteur et à un procédé de transmission de données dans un système dans lequel on utilise un procédé d'accès AMDC (accès multiple par répartition de code) et chaque signal de données (30) à transmettre est multiplié par un code pseudo-aléatoire (40) d'une certaine longueur et dont le débit binaire est supérieur à celui du signal de données devant être transmis. Afin d'assurer une réception rapide et peu coûteuse, on applique au signal multiplié par le code pseudo-aléatoire une modulation ultérieure par un groupe de formes d'onde (f1 .. fN) dont le nombre équivaut au nombre de bits dans le code pseudo-aléatoire, la fréquence de chaque forme d'onde étant comprise dans le domaine de fréquence donné. Selon ce procédé, le signal est converti dans le récepteur sous une forme numérique et multiplié par le code pseudo-aléatoire qui a été soumis à une transformation de Fourier inverse, après quoi le signal multiplié est soumis à une transformation de Fourier.
