Title: Sanding tool
Inventor: PANFILI LOUIS
IPC: B24D99/00
Filed: 2002-11-01
Granted: 2011-01-18
Abstract: A sanding tool having a plate with opposite sanding and supporting sides, a handle mounted onto the supporting side of the plate, and at least one fastening device operatively connected to the supporting side of the plate for fastening a sandpaper onto the sanding tool in such a manner that most of the sandpaper rests against the sanding side of the plate. Each fastening device has a clamping device and a guiding device. The clamping device is movable with respect to the supporting side of the plate between a first position where the clamping device is away from the supporting side and a second position where the clamping device rests operatively against the supporting side. The guiding device is used for guiding movement of the clamping device along a predetermined path between the first and second positions. In operation, a portion of the sandpaper is removably clamped between the supporting side of the plate and the clamping device when the latter is in the second position. The improved fastening device enables a sandpaper to be mounted onto the sanding toot in a quicker, easier, and simpler manner.

Filed: 2001-05-18
Granted: 2006-12-19
Abstract: The invention discloses a signal-to-interference ratio (SIR) measurement method. The method measures interference power (I) of a single-path signal after the received signal is demodulated by the single-path demodulators of multipath receiving device at the receiving end. The total interference power is obtained by equipartition combining with the measured interference power of each single-path signal. The signal power (S) is obtained by measuring after maximum ratio combination of each single-path signal. The SIR of the received signal is the division of the signal power and the total interference power. An apparatus, implementing mentioned method, sets the interference power measurement-device in the RAKE combiner and the signal power measurement-device after the RAKE combiner. In this way, the interference measurement can effectively provide more information and can more really response to the channel variation.

Title: Joint amovible elastomere, thermoplastique, essentiellement impermeable au gaz
Inventor: VARMA RAJESH KUMAR
IPC: B65D39/00
Filed: 2002-02-12
Granted: 2008-04-22
Abstract: L'invention porte sur un élastomère thermoplastique ("TPE") qui est perméable à l'oxygène et présente d'excellentes propriétés barrières à l'oxygène par mélange par fusion avec un plastifiant huileux de polybutène liquide dans une quantité insuffisante de façon à rendre l'élastomère plastifié collant. S'il est collant, on utilise une quantité suffisante d'un anti-adhésif pour pouvoir transformer le produit en un joint hermétique amovible. Le TPE peut être un vulcanisat thermoplastique traditionnel ou un copolymère séquencé d'un composé vinylaromatique, généralement le styrène, et un diène conjugué, généralement un butadiène ou isoprène, ou des mélanges de ceux-ci; la séquence peut être une diséquence, une triséquence ou une séquence supérieure, mais le copolymère polyséquencé préféré est formé par une triséquence comportant comme séquences terminales le styrène et comme séquence médiane butadiène/isoprène. De préférence, la séquence médiane diénique est hydrogénée de façon à produire une séquence médiane de poly monooléfine inférieure. Lorsque le TPE est un vulcanisat thermoplastique (TPV), une partie ou la totalité de l'huile minérale utilisée pour pourvoir traiter le TPV peut être également substituée par le plastifiant de polybutène. Le produit élastomère est notamment utile pour étanchéifier des éléments pour réceptacles dans lesquels peuvent être conservés, sur une longue durée des aliments, des boissons et des produits médicaux.

Granted: 2013-12-03
Abstract: A method is provided for tuning (i.e. modifying, changing) the impedance of semiconductor components or devices using a focused heating source. The method may be exploited for finely tuning the impedance of semiconductor components or devices, by modifying the dopant profile of a region of low dopant concentration (i.e.  increasing the dopant concentration) by diffusion of dopants from adjacent regions of higher dopant concentration through the melting action of a focused heating source, for example a laser. The present invention is in particular directed to the use of lasers in relation to circuits for the creation of conductive links and pathways where none existed before. The present invention more particularly relates to a means wherein impedance modification (i.e. trimming or tuning) may advantageously be carried out as a function of the location of one or more conductive bridge(s) along the length of a gap region.

Abstract: Système de protection destiné à un dispositif artificiel de levage artificiel qui comprend, sans toutefois s'y limiter, une pompe électrique submersible (ESP) et une pompe à cavité progressive submersible électrique (ESPCP). Le dispositif artificiel de levage est suspendu sur une colonne de tubage dans un puits de forage dans lequel le dispositif artificiel de levage entre en contact avec des fluides de puits. Le dispositif artificiel de levage est pourvu d'une barrière telle qu'une barrière d'admission ou d'une barrière de sortie qui empêche l'entrée de fluides de puits dans le dispositif artificiel de levage. En conséquence, le dispositif artificiel de levage peut rester inactif et submergé dans des fluides de puits pour une période prolongée sans que les éléments internes du dispositif artificiel de levage ne subissent une dégradation. La barrière d'admission peut comprendre un bouchon, une disque d'éclatement, un matériau soluble, une barrière sélectivement ouvrable tel qu'un manchon ou un élément sollicité par ressort ou un autre élément qui est capable d'assurer une barrière appropriée. On peut enlever la barrière une fois que le dispositif artificiel de levage est prêt à fonctionner. Le dispositif artificiel de levage peut être rempli d'un fluide protecteur. On peut prévoir un capteur de pression facultatif qui est en communication avec l'intérieur de l'unité d'appoint pour communiquer avec un compresseur pouvant être activé afin de maintenir une pression positive dans le dispositif artificiel de levage pour empêcher les fluides de puits de pénétrer dans l'unité. Le système de protection de l'invention est souhaitable pour la protection d'un dispositif artificiel de levage au repos, notamment lorsque le dispositif artificiel de levage est une unité d'appoint dans un déploiement de multiples dispositifs artificiels de levage.
