Title: Systeme d'alimentation electrique a ondulateurs monophases ou multiphases fonctionnant en parallele
Inventor: OLIVEIRA MARCOS PEGO DE
IPC: H02M7/493
Filed: 2003-12-23
Abstract: L'invention concerne un système d'alimentation électrique constitués d'ondulateurs (105, 110, 115) reliés en parallèle applicable principalement dans des blocs d'alimentation électrique sans interruption (UPS). Le parallélisme offre la capacité d'augmenter la puissance par le biais de la connexion au système de nouveaux ondulateurs ; ainsi que la fiabilité, les ondulateurs défectueux pouvant être retirés du système sans que l'alimentation électrique soit interrompue, car la capacité totale des ondulateurs restants n'est pas inférieure à celle requise par les charges. Dans un scénario de parallélisme, un des ondulateurs assure le rôle de maître, fonctionnant comme source de tension, les autres ondulateurs faisant office d'esclaves, fonctionnant comme sources de courant. Le maître informe les esclaves du courant de référence de chaque phase par le biais d'un bus de communication (150) entre les ondulateurs (105, 110, 115). La référence est informée comme valeur relative par rapport à la puissance nominale du maître, ce qui permet l'utilisation d'ondulateurs de puissance différente dans un système et une distribution de charges proportionnelle à la puissance nominale  de chaque ondulateur (105,110, 115).

Title: Commande de la quantite d'air permettant une commutation reguliere dans un moteur a injection directe de carburant
Inventor: LEE KI-HO
IPC: F02B27/02
Filed: 2000-10-05
Abstract: La présente invention concerne un moteur à injection directe de carburant qui est pourvu d'une conduite d'alimentation en air de dérivation. Ladite conduite de dérivation est sélectivement ouverte, afin de permettre l'arrivée d'un flux supplémentaire d'air dans la chambre du moteur pendant une phase de transition. Normalement, l'air s'écoule dans une conduite principale d'alimentation en air à travers un plénum. Cependant, lors d'une transition entre une phase d'injection précoce d'un faible volume d'air et une phase d'injection tardive d'un volume d'air relativement grand, la soupape est ouverte, afin de fournir un flux supplémentaire dans la conduite de dérivation. Ainsi, l'air peut être délivré plus rapidement à la chambre du moteur.

Title: Amplificateur de frequence radio de circuit integre a filtre coupe-bande
Inventor: ROGERS JOHN WILLIAM MITCHELL
IPC: H03F3/191
Filed: 2002-04-25
Abstract: L'invention concerne un récepteur radio superhétérodyne de circuit intégré, comprenant un filtre coupe-bande connecté à un amplificateur permettant d'amplifier des signaux de fréquence radio (RF) d'amplification afin d'améliorer un rejet de signal d'image. Le filtre coupe-bande comprend un premier circuit oscillant comportant un circuit oscillant final présentant une fréquence résonante correspondant audit signal de fréquence d'image non voulue. Un circuit de commande comprend un second circuit oscillant, un circuit polarisé maître et un circuit polarisé asservi. Le second circuit oscillant est sensiblement similaire au premier circuit oscillant. Le circuit polarisé maître réagit à une amplitude de signaux oscillatoires du second circuit oscillant pour limiter un courant fonctionnant par le biais d'un flux, de sorte que le second circuit oscillant est limité à un fonctionnement en état oscillatoire marginal. Un circuit polarisé asservi réagit par rapport au circuit polarisé maître pour, de manière similaire, limiter un flux de courant, pour faire fonctionner le premier circuit oscillant. Un transformateur de couplage est connecté entre l'amplificateur et le premier circuit oscillant pour échanger des énergies de signal entre le premier circuit oscillant et l'amplificateur, de sorte à ce que le premier circuit oscillant est réduit à un état de fonctionnement marginalement au repos, bien que chargé par l'amplificateur. Une impédance d'entrée de l'amplificateur est ainsi élevée à des fréquences proches de la fréquence de signal d'image, permettant ainsi d'améliorer le rejet de signal d'image.

Title: Partition structures and frame elements therefor
Inventor: SYKES CHRISTOPHER C
IPC: E04B2/74
Filed: 1989-10-13
Abstract: ABSTRACT            Partition structure has a rigid rectangular frame and rigid rectangular panels received in openings on opposite sides of the frame, with a small clearance between the edges of the panel and the frame.  One panel edge is pivotally connected to the frame.   The opposite edge of  the panel  is held securely on the frame by a resilient U-shaped catch received in a slot in a lip on the frame extending rearwardly of the panel.   The tongue can be deflected inwardly to free the shoulder from the lip by introducing a thin-bladed tool through the clearance between the panel edge and the frame, so that the panel can then be rocked outwardly about the pivotal connection to an open position.  A secure engagement of the panels on the frame is obtained, so that cables or other electrical equipment are securely housed within the partition.  By using a small clearance between the panel at the frame,  the tongues holding the panels  in place are practically indiscernible and the panel securing arrangement is rendered tamper proof.   There are also disclosed frame elements and partition structures arranged for stacking of modular frame elements one on another,  for connection of structures at angles to form corner units, for support of electrical cables within the frame elements, for attachment of the upper end of a partition to a ceiling,  and for levelling of a frame element on an uneven floor.

Filed: 1990-02-12
Abstract: An absorbent pad (1) such as an incontinence pad comprises a liquid-impervious back sheet (3) with spaced islands (4) of absorbent material thereon. A liquid-pervious cover sheet (7) has pockets (5) formed therein, in which the islands (4) of absorbent material are disposed. The cover sheet is secured, either adhesively or by heat sealing, directly to the impervious sheet (3) along lines that separate the islands of absorbent material and the pockets that contain them. The pad is formed by applying a strip of cover sheet material to a rotating multi-perforate drum and forming the pockets in the cover sheet material either mechanically, or by drawing hot air inwardly through the holes in the drum in the case of a heat-deformable material such as polypropylene fibers. The drum then rotates past a pocket-filling station, where absorbent material such as cellulose fluff is drawn into the pockets by vacuum applied internally of the drum. The cover sheet is then applied to the composite of cover sheet and absorbent material, and is firmly bonded to lines of cover sheet material that are free from absorbent material between the pockets, overlying the bridges that separate the holes through the drum. The composite is then removed from the drum and cut to size.

Abstract: The present invention is directed to a high-performance PVA fiber and its production. Each filament of the PVA fiber of the present invention has a structure comprising an aggregate of substantially innumerable fibrils, the fiber has high strength, elastic modulus, and resistance to fatigue, hot water and chemicals and can be pulpified while maintaining its excellent features, e.g. high strength. The PVA fiber of the present invention cannot, even drawn to a high ratio, be readily whitened by virtue of its fibril-aggregate structure, and can hence be made still higher in performances. The PVA fiber can be obtained by adding to a PVA solution a relatively large amount of surface active agent, and wet or dry-jet-wet spinning the thus prepared dope solution into an aqueous alkaline coagulating bath.

Title: Emergency rescue system
Inventor: BEACHAM ALLAN
IPC: G01S3/40
Filed: 1990-01-18
Abstract: The system is characterised by a personal transmitter (1) designed to be actuated in an emergency to emit a signal, an antenna (2A, 3) for receiving said signal, and a receiver (2) for receiving the signal from the antenna to activate an alarm, said receiver including a detector circuit (2B to 2K) which responds to variations in signal strength from the antenna for producing an audible (2Q) or visual (20) indication of said strength. Thus, when the receiver alarm is activated by said signal, the rescuer can assess the direction of the signal transmission by said variations in signal strength. In one arrangement, two antennae (9, 10) are provided for fixing to the masthead so that they are spaced apart to port and starboard, any signal received from a personal transmitter (1) being amplified by the receiver (2) to activate a boat alarm and thereby enable the helmsman to initiate man-overboard procedures. Thereafter, for locating the direction of the signal, said two fixed antennae (9, 10) are phased to provide left/right signal information for said receiver (2), which latter includes a display of the appropriate signal strength. In another arrangement, one fixed omni-directional antenna (2A) is provided for fixing to the masthead to pick up a signal from a personal transmitter (1) and operate a boat alarm. For locating the direction of the signal, a second, portable, directional antenna (3) is provided which is connected to said receiver (2) and, in use, is handheld and swept around the vessel to obtain a reading (6) of greatest signal strength. A test facility is built in to the system where at any time a transmitter and a receiver can be operated to test their function without causing alarms to other users.
