Patent CA-2480399-A1 (CA)
Title: Method for polymerisation of olefins with indeno-indolyl catalysts
Inventor: MACK MARK P
IPC: C08F110/02
Filed: 2003-03-18
Abstract: A method for making ethylene polymers and copolymers is disclosed. The metho d uses a catalyst system comprising a low level of an aluminum-containing activator, a bridged indenoindolyl transition metal complex, and a treated silica support. The method enables economical preparation of ethylene copolymers having very low density. The silica-supported, bridged complexes incorporate comonomers efficiently and are valuable for a commercial slurry loop process. Use of a bridged indeno[2,1-b]indolyl complex provides exceptionally efficient comonomer incorporation, and gives polymers with a substantial and controlled level of long-chain branching. The method facilitates the production of a wide variety of polyolefins, from HDPE to plastomers.

Title: Method for manufacturing barber scissors, and barber scissors
Inventor: BECK CHRISTIAN
IPC: B26B13/06
Filed: 2003-10-15
Abstract: The invention relates to a method for manufacturing barber scissors (1), wherein the scissor blades (23,33) are pre-shaped from blanks by a predetermined degree of curvature in the direction facing away from the edge. This is followed by welding on a hard metal material in the form of a welding bead on respective mutually facing faces of the scissor blades (23,33) to form the edges (24,34), wherein the preliminary curvature of the scissor blades (23,33) is neutralized owing to the influence of heat during the welding process. Subsequently the welding beads are ground so as to form the edges (24,34), and the scissor halves (2,3) are pre-set and hardened. Then the barber scissors (1) are hard-set in the assembled condition. The invention further relates to barber scissors (1) having such a configuration, where repeated frequent re-grinding or re-setting of the barber scissors (1) is possible without loss of functionality.
