Title: Extraits de cartilage de requin
Inventor: DUPONT ERIC
IPC: A61K33/14
Filed: 1996-08-07
Granted: 2002-07-30
Abstract: L'invention concerne des extraits de cartilage de requin et un procédé amélioré pour les produire. Ce procédé permet d'obtenir des extraits de cartilage de requin ayant des propriétés anti-angiogéniques, antitumorales, anti-inflammatoires et anticollagénolytiques. Ce procédé consiste à obtenir un homogénat de cartilage dans une solution aqueuse et à fractionner cet homogénat pour obtenir une fraction solide et une fraction liquide, cette dernière subissant un autre fractionnement permettant d'obtenir un extrait liquide présentant des molécules ayant un poids moléculaire compris entre 0 et 500 kDa. La composition de l'extrait liquide a été étudiée de différentes manières. Un fractionnement plus poussé de cet extrait a permis une caractérisation préliminaire de certains de ses composants actifs. Compte tenu de la multiplicité des effets biologiques observés avec l'extrait liquide total, celui-ci peut être utilisé pour traiter de nombreuses maladies ou de nombreux états, comme par exemple la prolifération de tumeurs, l'angiogénèse, les inflammations et la collagénolyse. Plusieurs applications cosmétiques découlant de la capacité de l'extrait liquide à améliorer les propriétés de barrière de la peau sont également du domaine de l'invention. Ces extraits n'ont aucun effet néfaste sur les fonctions normales du corps. Dans ces conditions, ces extraits de cartilage de requin sont très prometteurs pour des applications thérapeutiques. Le procédé d'obtention des extraits de cartilage de requin est simple et efficace. Ce procédé permettant d'obtenir des produits possédant des propriétés exceptionnelles, est original et novateur.

Title: Electric current switching apparatus with arc spinning extinguisher
Inventor: KRSTIC SLOBODAN
IPC: H01H33/08
Filed: 1998-07-02
Granted: 2005-02-01
Abstract: An electric arc extinguishing mechanism is provided for an electric current switching apparatus of the type having a pair of contacts which selectively engage to complete an electric circuit. The mechanism includes a plurality of splitter plates located adjacent to the contacts and formed of electrically conductive material. Each splitter plate has a body of electrically conductive material, and a casing with a pair of planar portions on opposite sides of the body and connected by the curved edge portion. The edge portion is adjacent the contacts with the planar portions extending from the edge portion in an open loop having a gap. Any arc introduced between adjacent splitter plates moves around the open loop before being extinguished thereby not residing in one spot long enough to cause gross melting and associated erosion of the splitter plate.

Abstract: A process for producing substantially impurity-free Bi-213 cations is disclosed. An aqueous acid feed solution containing Ac-225 cations is contacted with an ion exchange medium to bind the Ac-225 cations and form an Ac-225-laden ion exchange medium. The bound Ac-225 incubates on the ion exchange medium to form Bi-213 cations by radioactive decay. The Bi-213 cations are then recovered from the Ac-225-laden ion exchange medium to form a substantially impurity-free aqueous Bi-213 cation acid solution. An apparatus for carrying out this process is also disclosed.

La modification du catalyseur mise en oeuvre selon la présente invention permet de réduire les coûts de production et de produire une activité de catalyseur hautement fiable.
Patent CA-2309738-C (CA)
Inventor: POLANYI JOHN C
IPC: G03F1/00
Filed: 1998-11-06
Granted: 2010-01-26
Abstract: A method for mask-free molecular or atomic patterning of surfaces of reactive solids is disclosed. A molecular-scale pattern of adsorbate molecules is used in place of the conventional macroscopic "mask". Molecules adsorb at surfaces in patterns, governed by the structure of the surface, the chemical nature of the adsorbate, and the adsorbate coverage at the surface. The surface is patterned and then marked or imprinted with the pattern by inducing localised chemical reaction between adsorbate molecules and the surface of the solid, resulting in an imprint being formed in the vicinity of the adsorbate molecules. In one aspect of the invention, photoinduced or electron-induced reaction of the patterned adsorbate leads to patterned reaction with the surface. The reaction can take the form of patterned attachment to the surface (patterned "writing" or "doping") or patterned removal of atoms from the surface ("etching" which takes place in the initial reaction or through subsequent irradiation of the patterned surface). The adsorbate when irradiated with light, electrons or ions imprints a pattern on the substrate by localised reaction. The new method is exemplified by the case of a silicon substrate and chlorobenzene molecules which first adsorb in a pattern on a silicon crystal, and which when irradiated with light or electrons chlorinates the crystal in a similar pattern to that of the adsorbate. The presence of localised chemical reaction is demonstrated most directly by inducing reaction at a restricted locale and showing that this irradiaton-induced reaction occurs primarily at that same locale. The method is suitable for the writing, doping or etching of molecular-scale features.
