Patent CA-2394614-A1 (CA)
Inventor: CIBELLI JOSE
IPC: C12N15/09
Filed: 2000-05-10
Abstract: L'invention concerne une méthode de transfert nucléaire qui consiste à transplanter des noyaux de cellules donneuses différentiées dans des ovocytes énucléés d'une espèce différente de celle de la cellule donneuse, conjointement avec de l'ADN cytoplasmique et/ou mitochondrien compatible (de la même espèce que le donneur). Les unités de transfert nucléaire résultantes sont utiles pour la production de cellules souches embryonnaires isogènes, notamment de cellules souches ou embryonnaires isogènes humaines. Ces cellules embryonnaires ou souches sont utiles pour la production de cellules différentiées voulues et pour l'introduction, le retrait ou la modification de gènes voulus, par exemple dans des sites spécifiques du génome desdites cellules par recombinaison homologue. Lesdites cellules, qui peuvent contenir un gène hétérologue, sont particulièrement utiles dans les thérapies de transplantation cellulaire et pour l'étude in vitro de la différentiation cellulaire. L'efficacité du transfert nucléaire est accrue par l'introduction d'ADN cytoplasmique ou mitochondrien compatible (de même espèce ou similaire à la cellule donneuse ou au noyau donneur). Par ailleurs, l'efficacité du transfert nucléaire peut être encore éventuellement améliorée par la modification génétique des cellules donneuses pour l'inhibition de l'apoptose, par la sélection pour un cycle cellulaire spécifique et/ou par la mise en culture dans des conditions augmentant la croissance et le développement embryonnaire.

Title: Laser cutting method and apparatus for optical fibres or waveguides
Inventor: OSBORNE MICHAEL R
IPC: B23K26/40
Filed: 2001-10-25
Abstract: A cutting method and apparatus are provided to cut a portion of an optical fibre or waveguide with a laser beam. The proposed cutting action takes advantage of the sharp cutting edge of a laser beam generated so as to have a predetermined asymmetric intensity distribution. In operation, a prescribed amount of the beam distribution is impinged on the fibre or waveguide portion and causes the portion to ablate or vaporise so as to effect a cut at the portion in dependence upon the impingement. No translation of the laser beam across the fibre or waveguide is effected during cutting. The proposed cutting action bears definite advantages over conventional cutting techniques and finds utility for many optical fibre or waveguide applications. For example, the proposed cutting action can produce a substantially flat optical fibre or waveguide surface or a lens of enhanced quality at the end of the fibre or waveguide portion.

Inventor: BROWN STEPHEN JOHN
IPC: B29C41/00
Filed: 2003-07-24
Abstract: The cycle time for a rotomolding process is improved through the use of a molding material comprising a blend of at least two polyethylenes having narrow molecular weight distributions and homogeneous comonomer distributions. Alternatively, the molding temperature may be reduced to conserve energy and reduce energy costs. The polyethylene blend also has a narrow molecular weight distribution of less than 3 and a density of from 0.930 to 0.950 g/cc. Rotomolded parts prepared from the blend composition have excellent impact resistance and are also resistant to warpage. A preferred process employs a blend composition which contains a blend component having a higher molecular weight and a lower density than another blend component - this blend may be used to prepare rotomolded parts with warpage resistance and improved environmental stress crack resistance (ESCR). A highly preferred process uses a blend composition which further contains a minor amount (from 0.5 to 10 weight %) of a third ethylene blend component which has a higher molecular weight and density - this highly preferred composition may be used to prepare rotomolded parts having warpage resistance, very good ESCR and comparatively high modulus (or stiffness).
