Abstract: The umbrella-type clothes drier (1) possesses four supporting arms (3) fastened in an articulated manner to a supporting sleeve (4) which is displaceable along a vertical mast (2). The clothes drier (1) can be folded together as a result of the displacement of the supporting sleeve (4) in cooperation with a strut (8) assigned to each arm (3). The clothesline portions (7') extending between the supporting arms (3) hang down loosely when the clothes drier (1) is in the folded-together state. So that the umbrella-type clothes drier (1) does not have to be extended every time for individual articles or for small articles, a part (7a) of the clothesline (7) can be pulled out. So that the pulled-out part (7a) does not sag, the associated arm (3) can be locked and is equipped with a blocking device (11) for the pulled-out part (7a) of the clothesline. If appropriate, there can be a pull-back device (16) which pulls the released part (7a) of the clothesline into the folded-together clothes drier (1). <IMAGE>

Abstract: L'invention a pour objet une matrice d'éléments photosensibles, dans laquelle chaque élément photosensible se réduit à l'association d'une diode (D) et d'une capacité (C). Son procédé de fabrication est donc facile notamment à partir de silicium amorphe. Son procédé de lecture met en oeuvre une lecture multiplexée des colonnes : les n colonnes sont réparties en groupe de ? colonnes successives commandés simultanément par M registres à décalage horizontaux (RH1,...RHM), chacun associé à un intégrateur de lecture (A1,...AM). Pour assurer une lecture correcte des signaux utiles, quel que soit leur niveau, une remise à niveau de la tension (VP-VA) aux bornes des diodes des éléments photosensibles est effectuée afin que la tension de départ (VA0) au début de chaque impulsion de lecture appliqué à une ligne soit telle que seule, et même avec un signal d'éclairement utile maximum, cette impulsion ne puisse polariser la diode en direct, et que avec une impulsion d'adressage de colonne, la diode soit polarisée en direct même en l'absence de signal utile. Application, notamment, à la prise de vue d'images radiologiques.

Title: Biodegradable superparamagnetic materials used in clinical applications.
Inventor: GROMAN ERNEST V
IPC: C08G18/18
Filed: 1987-07-01
Abstract: This invention relates to materials exhibiting certain magnetic and biological properties which make them uniquely suitable for use as magnetic resonance imaging (MRI) agents to enhance MR images of animal organs and tissues. More particularly, the invention relates to the in vivo use of biologically degradable and metabolizable superparamagnetic metal oxides as MR contrast agents. Depending on their preparation, these metal oxides are in the form of superparamagnetic particle dispersoids or superparamagnetic fluids where the suspending medium is a physiologically-acceptable carrier, and may be uncoated or surrounded by a polymeric coating to which biological molecules can be attached. These materials are administered to animals, including humans, by a variety of routes and the metal oxides therein collect in specific target organs to be imaged; in the case of coated particles, the biological molecules can be chosen to target specific organs or tissues. The biodistribution of the metal oxides in target organs or tissues results in a more detailed image of such organs or tissues because the metal oxides, due to their superparamagnetic properties, exert profound effects on the hydrogen nuclei responsible for the MR image. In addition, the dispersoids and fluids are quite stable and, in the case of the fluids, can even be subjected to autoclaving without impairing their utility. Furthermore, the materials are biodegradable and, in the case of iron oxide compounds, can eventually be incorporated into the subject's hemoglobin, making them useful in treating anemia. Thus, the materials are well-suited for in vivo use.
