Patent EP-0277978-A4 (EP)
IPC: H03G3/32
Filed: 1987-08-12
Abstract: Un amplificateur à commande de gain adaptable (12) est décrit en relation avec un système audio, afin de permettre le réglage du volume de sortie d'un haut parleur (16) automatiquement en réponse à un signal d'interférence (21) tel qu'un bruit de fond. Ledit amplificateur comporte un circuit diviseur (30) qui calcule le rapport d'une moyenne de temps d'un signal altéré (20, 21) qui résulte de la combinaison entre un signal de sortie régulé (20) et le signal d'interface (21), afin de produire une tension de commande qui commande le gain de l'amplificateur. Afin de réduire la gamme dynamique du quotient dudit rapport, on incorpore dans le circuit diviseur (30) un circuit à rapport logarithmique. Les circuits de l'amplificateur comprennent ''un canal détecteur'' et ''un canal de référence'', afin de permettre l'extraction desdites moyennes respectivement du signal altéré et du signal de sortie régulé. Un procédé est également revendiqué.

Title: Venous cuff applicator, cartridge and cuff.
Inventor: KOHLER WOLFGANG WERNER
IPC: A61B17/12
Filed: 1988-02-10
Abstract: An applicator for applying a strap around a vein at the site of a defective venous valve includes a handle portion (11) and a removable cartridge (13). One end of the strap is anchored on the anvil (60) of the cartridge (13) and the free end is looped around the vein and passed through an opening (71) in the cartridge adjacent to the anvil (60) to overlie the anchored end. The free end of the strap is connected to a strap puller within the cartridge which is coupled to a strap puller extension within the handle (11) when the cartridge (13) is inserted in the handle (11). The perimeter of the loop is adjusted by moving the tensioner (17) on the handle (11). When the perimeter of the loop is at its desired value, the triggers (18) on the handle (11) are pressed to drive a staple through the overlying portion of the strap. A knife within the cartridge (13) cuts excess strap from the loop.

Patent EP-0549719-A4 (EP)
Title: Positive seal coupling internal joining press
IPC: B25B27/02
Filed: 1991-09-18
Abstract: This invention is a new apparatus for installing press fit couplings about steel pipeline sections. Conventional apparatuses are extremely large, usually requiring extensive mounting equipment, and are incapable of being used in the confined spaces of a pipe trench. This invention solves the problem with a small, compact pipe coupling apparatus which is easily maneuvrable in tight spaces. The apparatus (10) fits within two pipes (1, 2) to be joined, with a coupling (3) disposed between them. Two hydraulically actuated grippers (6, 7) grip the insides of both pipes (1, 2), respectively, and a hydraulically actuated cylinder (5) is operated to pull the pipes (1, 2) together, press fitting the coupling (3) about them. The entire apparatus is controlled using only two hydraulic lines (8). The grippers (6, 7) can be retracted and the apparatus moved within the pipeline from one joint to the next. The invention is also applicable in joining two sections of pipe without the use of a coupling.

IPC: A61B5/028
Filed: 1992-02-07
Abstract: Cathéter de thermodilution (100) pourvu d'un filament chauffant (400) suffisamment fin et flexible pour éviter tout contact avec le sang du patient. Le filament chauffant est soit inséré dans une lumière de cathéter préformée, soit incorporé à une paroi du corps du cathéter, soit enroulé autour de la paroi du corps de cathéter et protégé par une gaine (404). Généralement, l'enveloppe du filament chauffant est aussi fine que possible de manière à permettre le transfert de la chaleur dégagée par le filament chauffant (400) dans le sang environnant, et d'augmenter le moins possible la section totale de l'ensemble. Etant donné que le filament chauffant (400) ne touche pas directement le sang du patient, sa surface extérieure peut être rendue lisse afin d'empêcher la formation de caillots de sang. De plus, il est possible de maintenir le filament chauffant (400) à une température sûre au moyen d'un élément chauffant fabriqué dans une matière flexible présentant un haut coefficient de résistance à la chaleur, une faible chaleur spécifique et une conductivité thermique élevée.

Title: Multi-stage drug delivery system
Inventor: AMIDON GORDON L
IPC: A61K9/48
Filed: 1993-04-20
Abstract: A drug delivery system (10) includes a first capsule half (12) having an inner chamber (16) for containing a drug (18) therein. A plug (28) is disposed in a passageway (26) of the capsule half (12) for plugging the opening (24) thereof. The plug (28) is releasable from the passageway opening (24) upon the application of pressure from within the inner chamber (16).  A pump mechanism, reactive with the external environment of the capsule half (12), causes an increase in pressure within the inner chamber (16) and forces the plug (28) out of the passageway (26) to release the drug (18) from the inner chamber (16) and out of the passageway (26). Thusly, after initial release of drug from a second capsule half (14) releasably mounted on the first capsule half (12), the first capsule half (12) provides a second pulse of drug release at a predetermined time after initial ingestion of the capsule. The invention further provides a method of manufacturing the drug delivery system (10) and method by which the drug delivery system (10) provides the drug to a body.

Abstract: L'utilisateur d'une serrure à combinaison électronique auto-alimentée fait tourner un cadran extérieur (101) afin que des générateurs génèrent de l'énergie qui sera stockée dans une banque de condensateurs. L'utilisateur fait ensuite tourner un cadran intérieur (102) afin qu'un microprocesseur affiche en séquence des combinaisons de chiffres, et appuie sur le cadran intérieur (102) pour sélectionner un nombre affiché. Un microcontrôleur détermine le sens et l'ampleur du mouvement du cadran intérieur par la réception de signaux dérivés de capteurs Wiegand placés à proximité d'un disque aimanté qui tourne solidairement du cadran intérieur, et il commande en conséquence l'affichage de chiffres sur un affichage à cristaux liquides. Lorsque le microcontrôleur détermine qu'une combinaison correcte a été entrée, il active un moteur (201) qui déplace une came (205) de moteur de telle sorte qu'elle agisse directement sur un levier de verrouillage (213) pour que ce dernier puisse se mettre en prise avec une came d'entraînement (218) reliée d'un seul tenant au cadran intérieur, afin que le cadran intérieur puisse retirer le pêne de la serrure.

Title: Method of air filtration for fire fighter emergency smoke inhalation protection
Inventor: SMITH DENNIS
IPC: A62B23/02
Filed: 1995-08-31
Abstract: A method of emergency smoke inhalation protection of fire fighters in imminent life-threatening situations includes configuring a canister containing a filter medium to evidence use. The canister has an opening through which air enters and has a coupling for attachment to the mask of a standard self contained breathing apparatus in place of a connection to an air tank. When so connected, air drawn into the mask passes through the filter medium within said canister. A use-evidencing mechanism is operatively connected to the canister to indicate use of the air filtering system. This mechanism can be non-reusable covers applied over the opening and coupling, or a sealed package containing the air filtering system. Such devices provide an indication of previous use of the filtering system and inhibit a fire fighter from using the system in an unauthorized manner.
