Patent CA-2309469-A1 (CA)
Inventor: HANNA EMMANUEL A
IPC: A47K5/12
Filed: 2000-05-25
Abstract: A system for dispensing liquids, particularly a system for dispensing liquid soap through at least one hand-operated pump. The system includes a pump, a main reservoir for holding a first quantity of the fluid to be dispensed, and an auxiliary reservoir for holding a second and generally smaller quantity of fluid. The main reservoir, auxiliary reservoir, and pump are in fluid communication with one another through a coupling. The system and coupling are configured so that the fluid is drawn preferentially from the main reservoir, with fluid being drawn from the auxiliary reservoir only when the main reservoir is substantially emptied of fluid.  Additionally, any fluid that is drawn from the auxiliary reservoir will be replenished automatically by fluid in the main reservoir as long as any fluid is present in the main reservoir.

Title: Fitment having removable membrane
Inventor: ADAMS BRIAN M
IPC: B31B1/84
Filed: 1999-03-31
Abstract: A fitment (16) for use as a pour spout has a flange which is secured around a hole in a container.  The spout projects outwardly from the container and has a removable interior membrane (32). A horizontal pull ring (39) is attached to the membrane. Pulling the ring removes the membrane by fracturing the tear line (36) at the juncture of the the membrane and the spout. A screw-threaded cap snaps over the spout.

Inventor: FLINN BARRY
IPC: C12N15/82
Filed: 1999-09-15
Abstract: Methods for producing genetically modified plants, particularly woody plants, and most particularly plants of the Eucapyptus and Pinus species, involve transformation of target plant material with a desired genetic construct and regeneration of the transformed plant material using an adventitious shoot bud system. The methods provide a high transformation efficiency and substantially reduce the duration of the transformation and regeneration protocols. Stem segments of a target plant are transformed using Agrobacterium-mediated techniques, and adventitious shoot buds are regenerated from the Agrobacterium-infected stem segments. Preferred culture media, including selection media, and improved plant culture techniques are disclosed.
