Abstract: A transcatheter occluding intracardiac defect device comprizes a folding poly-urethane foam(16) with Teflon coated wire skeleton(12), introducible into a long vascular sheath sheath(40) and automatically unfolded upon delivery in the distal to the defect cardiac chamber. A two mm string loop(14) is attached to the center of the occluder(10), while the loop is closed by 1 mm knot(18). A loading wire (28) comprizes a Teflon hollow wire(30) and a double mono-filament thread which carries the occluder on one end and is tied on the other end. An occluder holder(20) comprizes a rhomboid poly-urethane foam with Teflon coated wire skeleton and a "rubber" piece(24) sutured in the center. The occluder-holder(20) is advanced over the the loading wire(28) axis and through the long sheath(40) in the proximal to the defect cardiac chamber and is pushed against the occluder(10) till it is securely buttoned. The distal end of the loading wire(36) is cut and the hollow wire (30) is pulled out over the double thread. The thread is pulled as a single strand and therefore the device is released.

Abstract: Le procédé décrit, qui sert à fabriquer du tantalate de scandium de plomb de pérovskite, consiste à faire subir une pré-réaction à des oxydes de scandium et de tantale à des températures comprises entre 1000°C et 1400°C pour produire du tantalate de scandium. Le tantalate de scandium est ensuite mis en réaction avec de l'oxyde de plomb pour former le tantalate de scandium de plomb en phase perovskite désiré. Dans un mode de réalisation, la présente invention décrit un procédé de dépôt de films de tantalate de scandium de plomb de pérovskite à partir de précurseurs organo-métalliques. La possibilité d'utiliser des précurseurs organo-métalliques permet le dépôt de couches minces directement à partir d'une solution ou par des techniques MOCVD (dépôt en phase gazeuse par procédé chimique de type organo-métallique). Un matériau de ce type, le tantalate de scandium de plomb Pb(Sc0,5Ta0,5)O3, est en particulier décrit. Les caractéristiques principales de la présente invention sont le dépôt de constituants de scandium et de tantale à partir d'une solution ou par MOCVD sur le substrat requis. Ces constituants sont ensuite mis en pré-réaction pour produire du tantalate de scandium. Un film ou de la vapeur contenant du plomb est ensuite mis en réaction avec le tantalate de scandium pour former le tantalate de scandium en phase pérovskite.

Abstract: Procédé permettant d'enlever en une seule étape deux ou plusieurs contaminants d'un substrat, qui consiste à mettre en contact le substrat à nettoyer avec un gaz à phase dense à une pression égale ou supérieure à sa pression critique, à faire varier ensuite la phase du gaz à phase dense entre l'état liquide et l'état surcritique en modifiant par une série d'étapes la température du fluide dense entre une température supérieure et une température inférieure à la température critique du fluide dense. Après chaque variation de température, cette dernière est maintenue ainsi pendant un laps de temps prédéterminé pour permettre le contact avec le substrat et les contaminants et permettre l'élimination de ceux-ci. A chaque variation de température, le gaz à phase dense présente différentes densités d'énergie cohésive ou propriétés de solubilité. Grâce aux changement de phases du fluide dense, on peut ainsi enlever une pluralité de contaminants du substrat sans devoir utiliser différents solvants. Dans d'autres modes de réalisation, on peut également recourir au traitement par les radiations ultraviolettes, à l'énergie ultrasonique, à un gaz réactif à phase dense ou à des additifs.

Abstract: In the transfer sections 1 of a chairlift having a circulating conveying rope 2, the deceleration and acceleration sections 4 and the exit and entrance sections 12 are provided with friction wheels 6 and 10 which together define a travel path 20 for the in-coming and out-going chair 50. The chairs 50 are supported on this travel path with in each case one U-shaped running rail 80 which is downwardly open and contains a concave friction surface 88. Each running rail 80 is rigidly connected to the running gear element of the associated chair. The friction wheels 6 and 10 which are constructed as wheels with pneumatic tyres have guide edges which interact with guide surfaces of the running rails and ensure that the chairs move in a straight line. 
<??>In the sections provided with the friction wheels, fixed travel rails for supporting the chairs are thus superfluous. The running gears of the latter can be of very compact design. (Fig. 1).

Date Jul. 26, 1990.The invention relates to a motor-driven control valve for a liquid, in which a control member (31) effects a rotatory and/or linear motion. In order to achieve an improved torsion moment and controllability, the motion of the control member is produced by means of an ultrasonic motor. In one embodiment, the rotating plate acting as a control member (31) forms directly a mobile part of the ultrasonic motor. An oscillating body (36) is in contact with this part, the oscillations of the body being produced by piezoelectric elements (37). The oscillating body (36) with the piezoelectric elements (37) can be annular, thus surrounding e.g. the material flowing in the pipe. Owing to the invention, a compact and simple solution is provided, and the actuating of the plate does not require as many transmission elements as when usual electric motors are being used.

Title: A moderated spun fibrous system and method of manuacture.
Inventor: FUISZ RICHARD C
IPC: A61K9/70
Filed: 1990-02-22
Abstract: A spun product from a combination of a saccharide and a hydrophobic ingredient is hydrophilic with low concentrations of such ingredient but becomes increasingly hydrophobic as the concentration of the hydrophobic ingredient is increased, although the end product nevertheless acts hydrophilically when the water temperature is elevated. Larger ratios of hydrophobic substance-to-saccharide yields a spun fibrous product that has increased stability. Similar stabilization can be attained by adding either beeswax or a petrolatum to the saccharide either in the presence of or absence of a separate active ingredient. Examples are given for masking the taste of unpalatable medicaments or other ingestible substances. Delayed release burn or wound dressings are also described. Control with beeswax can also provide a time release tablet or the like when swallowed.

Abstract: Un capteur contenant au moins un transducteur piézoélectrique (1) est exploité par une seule ligne commune de signaux (2) dans ses deux modes possibles de fonctionnement. Dans le cas de basses fréquences, il sert d'élément de mesure d'une grandeur mécanique, au moyen de l'effet piézoélectrique direct, et dans le cas de fréquences plus élevées, il sert de résonateur piézoélectrique, utilise l'effet piézoélectrique inverse pour exciter électriquement des vibrations mécaniques et l'effet piézoélectrique direct pour générer une rétroaction piézoélectrique. Un signal de haute fréquence (uHF, uF) qui décrit la caractéristique de résonance et un signal de basse fréquence (uNF, uQ) qui décrit l'effet mécanique sont générés à partir du signal de mesure transmis par la ligne de signaux (2). On peut ainsi par exemple contrôler directement pendant une opération de mesure effectuée à l'aide du capteur son fonctionnement ainsi que celui de l'amplificateur correspondant de mesure, ou mesurer en même temps deux grandeurs différentes.
