Dans la forme de réalisation préférée le dispositif est constitué de matrices polymères biodégradables bien que les réservoirs puissent également être formulés à partir de polymères non biodégradables ou de réservoirs connectés à des pompes à perfusion implantées. Les dispositifs sont implantés dans les tumeurs ou immédiatement à côté des tumeurs à traiter ou du site où elles se trouvaient avant leur élimination par chirurgie. Les exemples démontrent l'efficacité du paclitaxel, de la camptothécine et du carboplatine libérés dans des implants polymères préparés par moulage par compression de polymères biodégradables et non biodégradables, respectivement. Les résultats sont profondément significatifs du point de vue statistique.

Granted: 2001-04-10
Abstract: A binder solution for providing an electrode suitable for use in non-aqueous-type electrochemical devices, such as a battery and an electric double layer capacitor, is formed by dissolving a vinylidene fluoride polymer having an inherent viscosity (and thus a polymerization degree) higher than a conventional level in an organic solvent.  An electrode-forming composition is formed by dispersing powdery electrode material in the binder solution and is applied onto an electroconductive substrate while avoiding the gelation of the polymer, followed by drying, to form a composite electrode layer, which retains the powdery electrode material at a smaller amount of vinylidene fluoride polymer than a conventional level and is well resistant to a non-aqueous electrolytic solution.

Title: Signal processing
Inventor: MCEWEN ROBERT KENNEDY
IPC: H04N5/365
Filed: 1995-11-24
Granted: 2005-07-05
Abstract: A signal processor (10) receives both open and closed field values for elements of a detector (11) and corrects for non-uniformities in offset response between the elements prior to converting the signal to a digital signal via an A to D converter (15). The corrected signal is then digitally processed to compensate for linear and higher order non-uniformities in the response of the element. The invention enables the A to D converter to have relatively low resolution for a given output radiation.

Title: Disk for the skis of a snowmobile
Inventor: LEMAY SERGE
IPC: B62B17/02
Filed: 1998-11-04
Granted: 2000-10-31
Abstract: A front ski assembly for mounting on a steering column of a snowmobile is provided. The front ski assembly includes a ski, a disk-shaped rigid wheel and a bearing assembly to mount the wheel on the steering column. A slit is made in the ski along its longitudinal direction, beside the lower portion of the steering column. A runner shoe is fixed on the bottom surface of the ski and projects from the same. The wheel is sized so it partially extends in the slit when mounted on the steering column, and projects from the bottom surface of the ski further than the runner shoe. The wheel therefore allows to better control the snowmobile when circulating on hard surfaces. The invention also concerns a snowmobile provided with two such front ski assemblies and a kit to allow manufacturers, resellers or owners to install a wheel assembly on a snowmobile.
