Title: Catheter device and filter for vena cava
Inventor: LUCIEN GUELFI
IPC: A61M25/04
Filed: 1989-09-27
Abstract: The invention relates to a filter device with a central passage for positioning in the vena cava. It consists of a filter-holding catheter (4) inside which there slides a filter/cable/rod assembly comprising a rigid proximal interconnected section (5), a flexible section (7), an intermediate rigid interconnected section (8), a filter with multiple strands (9) and a rigid distal interconnected section (10); inside the filter/cable/rod assembly (5, 7, 8, 9, 10) there is formed a central passage in which a micro-catheter (11) can be mounted. The proximal section (5) of the multi-part device is pushed in order to force the filter (9) and the micro-catheter (11) out. When the filter-holding catheter (4) has been pushed out, the filter (9) is opened out and the distal end of the micro-catheter is positioned distally at the end of the rigid distal section (10) of the multi-part device. The invention applies to the prevention of pulmonary embolisms.

Title: Methode pour la determination de la profondeur d'une zone de fracture hydraulique dans la terre
Inventor: MAHRER KENNETH D
IPC: E21B47/00
Filed: 1989-11-29
Abstract: La profondeur d'une zone de fracture hydraulique est déterminée par la détection et l'enregistrement de mouvements sismiques ondulatoires en une série de points espacés les uns des autres en profondeur dans une partie d'un trou foré 10 soumis à la pression de fracture durant une période d'obturation après l'application d'une pression pendant que la zone de fracture est encore instable, et par l'analyse desdits enregistrements de mouvements permettant de séparer et d'éliminer les composantes non attribuables à la fracture des composantes discrètes d'origine sismique attribuables à la fracture pour déterminer un niveau moyen de base des composantes verticale et horizontale et comparer le niveau moyen de base des composantes horizontales du mouvement à la composante verticale du mouvement afin d'obtenir une indication sur la présence ou l'absence de fracture à chacune des profondeurs considérées.

Title: Dispositif et procede pour la commande de la vitesse des helices d'un avion
Inventor: SUN MICHAEL JOHN
IPC: F02C9/58
Filed: 1989-12-06
Abstract: La présente invention concerne une commande 123 pour une hélice d'avion. Pendant la marche avec le pas correspondant à une inversion de la poussée, comme cela se produit lors d'une manoeuvre d'atterrissage, on commande la vitesse de l'hélice par le réglage 128 de son pas, de manière à éviter les sur-vitesses. En outre, pendant la période de transition au cours de laquelle l'hélice voit son pas passer pour une poussée vers l'avant à une inversion de la poussée, l'hélice présente une charge légère pour le moteur. A ce moment-là, le débit du carburant du moteur est limité de manière à restreindre la fourniture d'énergie à hélice, là encore dans le but d'éviter les sur-vitesses. Application aux systèmes d'avion propulsés par des hélices.

Patent FR-2670531-A1 (FR)
Inventor: HUBERT FAY
IPC: G01P3/64
Filed: 1990-12-12
Abstract: The method involves using signal emission means (5) and at least two reception units (8, 10) at two different locations along the well equipment (2). Each unit produces an image or signature of the well portions passing it. The images produced by the unit (8) in the lowest position when the equipment (2) is descending are stored for the necessary time period so that, when the equipment has penetrated further, the other unit (10) receives signals from the same portion of wall and also produces an image. By comparing (e.g. by correlation) images from each of the two units, it is possible to identify the common portion of the wall which has produced the two images being compared. The time period between the formation of the two matched images is measured, and the rate of penetration calculated. The invention may be applied to measuring the true rate of penetration of a well tool or measuring probe.
