Patent CA-2383410-A1 (CA)
Inventor: MARTI HEINRICH A
IPC: B22D11/11
Filed: 2000-08-16
Abstract: The invention relates to strip casting machines comprised of two parallel casting rollers (1,2) whose bearing journals (8,9) are supported on a stand (3). Cooled roll barrels of the casting rollers (1,2) and narrow lateral parts (5) delimit a casting gap (6). The aim of the invention is to obtain an optimal ratio between the width of the casting machine and the maximally castable strip width, to provide for a simple stand construction both for changing rollers as well as for exchanging narrow lateral parts, and to attain an improved protection against oxidation. To these ends, the invention provides that the cooled roll barrels are constructed as cylindrical casings (4). The casing (4) should be supported on a stationary axle, which is fixed on the stand (3), via the concentric support rings which project inside the casing (4) on both sides and which are connected to the same.

Title: Treatment of dermal tumors, warts, and viral infections using heat-killed p. acnes
Inventor: VAN KAMPEN KENT R
IPC: A61K35/74
Filed: 2000-10-13
Abstract: Heat-killed, terminally sterilized saline suspensions of Propionibacterum acnes, Propionibacterium avidum, Propionibacterium lymphophylum, Propionibacterium granulosum, Cornynebacterium parvum, and Arachnia propioni ca are effective in treating viral infections of the respiratory tract in human s, and to induce the regression of dermal tumors and warts in humans. The poten cy of a saline suspension of heat-killed, terminally sterilized saline suspensi on of Propionibacterium acnes (P. acnes) was demonstrated through a laboratory animal challenge model. The P. acnes product is administered orally for the purpose of preventing or treating viral infections of the respiratory tract in man. The P. acnes preparation is intralesionally administered into dermal tumors, warts such as plantar warts, or other warts in people caused by the human papilloma virus, to cause regression of such dermal tumors and warts. The subcutaneous route of administration of the P. acnes product causes a systemic reaction that causes long-term warts to completely regress. Anesthetics such a Lidocaine may be added to the P. acnes product to prevent  pain upon injection of this immune modulating preparation, while retaining t he potency of the P. acnes product. Dose ranges have been established for the oral administration of the P. acnes product to treat viral infections, and f or the subcutaneous and intralesional administration of the P. acnes product to  treat dermal tumors and warts.

Patent CA-2389950-A1 (CA)
Inventor: GAGNON ROBERT
IPC: C10G1/00
Filed: 2002-06-28
Abstract: The invention provides a process for producing synthetic crude petroleum from carbon compounds-organic wastes in virtue of hydrogenation using two natural catalysts instead of one or many costly industrial catalysts. The process recreates in industry natural conditions of petroleum formation as they existed millions of years ago. Using two natural catalysts, conversion of heterogeneous organic wastes is now not only possible but also profitable because production efficiency of synthetic crude is improved by more than 50%. While recycling unwanted heterogeneous organic wastes, the process has the advantage of producing a valuable product. Doing so, petrolisation is a permanent solution to organic waste problems and a permanent source of valuable crude.

Title: Method for the improvement of islet signaling in diabetes mellitus and for its prevention
Inventor: GLUND KONRAD
IPC: A61K38/00
Filed: 2001-04-02
Abstract: The present invention discloses a method for therapeutically treating mammals, including but not limited to humans, to increase the relative insulin producing performance of endogenous pancreatic .beta.-cells and to cause differentiation of pancreatic epithelial cells into insulin producing .beta.-cells. Oral administration of a DP IV inhibitor causes the active form of GLP-1 to be preserved longer under physiological conditions. The extended presence of GLP-1, in particular in the pancreatic tissue facilitates differentiation and regeneration of the .beta.-cells already present that are in need of repair. These repaired insulin producing cells can contribute to the correction and maintenance of normal physiological glycemic levels.
