Title: Ga4 dna, protein and methods of use
Inventor: CHIANG HUI-HWA
IPC: A01H5/00
Filed: 1995-08-15
Abstract: The invention relates to the DNA and protein encoded by the GA4 locus. This protein is believed to be a member of the family of enzymes involved in the biosynthesis of the gibberellin family (GA) of plan growth hormones which promote various growth and developmental processes in higher plants, such as seed germination, stem elongation, flowering and fruiting. More specifically, the protein encoded by the GA4 locus is an hydroxylase. The invention also relates to vectors containing the DNA and the expression of the protein encoded by the DNA of the invention in a host cell. Additional aspects of the invention are drawn to host cells transformed with the DNA or antisense sequence of the invention, the use of such host cells for the maintenance, or expression or inhibition of expression of the DNA of the invention and to transgenic plants containing DNA of the invention. Finally, the invention also relates to the use of the protein encoded by the GA4 locus to alter aspects of plant growth.

Patent CA-2199202-A1 (CA)
Inventor: BERDAN KARL
IPC: B29L9/00
Filed: 1997-03-05
Abstract: The invention relates to a process for the reworking of molded pieces made of thermoplastic material, which are coated over part of their surface with a film and which have a margin of the film extending beyond the molded piece. Because cutting of the edge margin along the parting line can cause it to become detached or loosened, it is proposed according to the invention to laminate at least a portion of the film margin against an as yet surface portion of the molded piece. This is carried out in a reworking apparatus in which the film margin is folded by guide rolls, then if necessary is cut to a predetermined width in a cutting apparatus, then is pressed by pressure rolls against the surface region, then together with the latter is warmed in a laminating apparatus, in order to weld the film margin to the surface region, whereupon the warmed region of the molded piece is again cooled in a cooling apparatus.

Patent CA-2203037-A1 (CA)
Inventor: CHAN JOHN ABRAHAM YUK WAH
IPC: B62J27/00
Filed: 1997-04-18
Abstract: A body based air bag is a light-weight air bag module that attached to, or mounted to the vehicle occupant such that when the air bag deploys, its base will stay in contact with the human body as a support to expand outward. The impulsive reaction force due to air bag inflation, being act at opposite direction of the inertial body movement, will retard the human body before the air bag is functioned as a protective cushion. As a result, the requirement for an instant inflation is minimized so that the damages caused by the air bag is substantially reduced. Since the air bag is body based, it is customized to fit vehicle occupants according to their age, gender, height and weight. The body based air bag module is easily removable and replaceable. It can protect vehicle occupants from all types of accidents regardless of their seating position.
