Abstract: On décrit un système destiné à produire des images représentant la répartition de la dose de rayonnement de manière à vérifier la dose de rayonnement appliquée sur une zone cible, et dans lequel on utilise un ensemble fantôme réalisé dans un matériau qui est l'équivalent radiologique d'un tissu vivant. Cet ensemble fantôme possède des fentes dans lesquelles on peut insérer un film (28) sensible aux rayonnements et peut comprendre un canal destiné à l'insertion d'un dispositif de production de rayonnements. La dose de traitement est ensuite appliquée à l'ensemble fantôme et le film sensible aux rayonnements enregistre la dose. On utilise ensuite un microdensitomètre doté d'une caméra (20) à CCD afin de lire le film qui a été exposé. Ce microdensitomètre à CCD comprend un système (60) informatique qui traite l'image afin d'enlever les artéfacts et produit des contours isodoses pour le traitement aux rayonnements appliqué. En outre, plusieurs parties dudit film situées dans différents plans peuvent être exposées et traitées de manière à produire des images tridimensionnelles de la répartition de la dose de rayonnement.

Title: Hydrostatic self-loading controlled deflection roll
Inventor: BROWN DALE A
IPC: D21G1/02
Filed: 1995-08-10
Abstract: A hydrostatic self-loading controlled deflection roll has a central, hydraulically operated shoe which extends substantially the entire cross-machine width of the rotating roll shell (1), and two outboard shoes (24, 26, 28, 30) disposed, in the cross-machine direction, outside of the nip loading zone. The use of the outboard shoes (24, 26, 28, 30) permits the use of a single, full-length nip shoe (3) within the nip loading zone, which simplifies control and provides for more uniform temperature distribution. The outboard shoes (24, 26, 28,30) also provide better crown control. The outboard shoes (24, 26, 28, 30) are preferably disposed within a head flange (17, 18) area of the roll, at the location where spherical bearings would normally be present in a conventional roll. A bearing ring is disposed axially outside of the head flange (17, 18) and around a portion of a bearing box at either end of the roll for rotatably supporting the roll shell about bearings in the bearing box. A barrier seal is disposed between the stationary roll shaft and the roll shell (1) intermediate the bearings and outboard shoes (24, 26, 28, 30).

An air/fuel mixture inlet aperture (14) as well as an exhaust aperture (15) are located in the wall of the second cylinder (8) and are opened or closed by the movement of the second piston (7). There is a further exhaust sealing valve (17) such as a rotary disc valve which opens or closes an exhaust port (16) connecting the exhaust aperture (15) to the outside (or exhaust system), the sealing valve (17) closing the exhaust port (16) so as to prevent exhaust gases from reentering the combustion chamber (12) when the engine is in its intake stroke and when the exhaust aperture (15) is not covered by the second piston (7). The air/fuel mixture enters the combustion chamber (12) through a one-way valve (13), usually a reed valve.

Patent CA-2209367-A1 (CA)
Inventor: LARY BANNING GRAY
IPC: A61B17/22
Filed: 1997-07-03
Abstract: The present invention is a device and a method for boring a perfusion channel into the myocardial tissue of a patient. Structurally, the present invention includes a positioning catheter and a cutting catheter. The positioning catheter is formed with an inflation lumen and a deployment lumen and has an inflatable balloon mounted at its distal end. The cutting catheter has a sharpened distal end and is advanceable through the deployment lumen of the positioning catheter. Advancement of the cutting catheter through the deployment lumen causes the distal end of the cutting catheter to be directed radially outward from the positioning catheter. In use, the positioning catheter is positioned within a target vessel. The inflatable balloon is then expanded to anchor the distal end of the positioning catheter.      The cutting catheter is then advanced through the deployment lumen, projecting the distal end of the cutting catheter radially outward from the positioning catheter, boring a perfusion channel in the tissue adjacent to the target vessel.

Title: A process for preparing epirubicin or acid addition salts thereof from daunorubicin
Inventor: SCHEEREN JOHAN WILHELM
IPC: C07H15/252
Filed: 1997-12-15
Abstract: This invention relates to a novel method for the chemical preparation of epirubicin or acid addition salts thereof, in particular the HCl salt, from daunorubicin. This process avoids the disadvantages of the prior art. First daunorubicin is methanolized to obtain daunomycinone and dauriosamine methyl ether in very high yields. Daunomycinone is converted to 14-acetoxy daunomycinone by bromination and acetoxylation, while daunosamine methyl ether is converted into an N-protected 4'-epi daunosamirie. The choice of the protecting group of the amino group of the daunosamine methyl ether is important because it has to be removed after coupling the sugar with the aglycone without causing side reactions of the aglycone. Two protecting groups were selected: the trifluoroacetyl group and the allyloxycarbonyl group. After coupling the 14-acetoxy daunomycinone with the N-protected 4'-epi daunosamine, the obtained compound was converted to epirubicin; for the latter conversion two routes were developed, depending on the amino-protecting group.
