Patent number: 7921900Abstract: A process for forming an article includes locating a container containing a charge of semi-solid metal alloy in a passage in front of a plunger arranged to travel relative to the passage to force the charge of semi-solid metal alloy into a desired shape, and displacing the charge of semi-solid metal alloy from the container and forming it into the desired shape by causing relative travel between the plunger and the passage. The plunger can push a displaceable closure member to displace the closure member and the charge of semi-solid metal alloy along an interior volume of the container from a first opening proximal the plunger and closed by the closure member towards a second opening remote from the first opening.Type: GrantFiled: June 22, 2010Date of Patent: April 12, 2011Assignee: CSIRInventors: Hristov Lillian Ivanchev, Daniel Jeremias Wilkins

Patent number: 7730822Abstract: A body and any occupant of a land vehicle (10) is protected against effects of a landmine explosion, by conducting shock waves laterally outwardly by means of one or more shock wave guide members (16, 18) of a material having high acoustic velocity, and located proximate a ground engaging element (12) of the vehicle. The material may be glass, ceramic or the like having an acoustic velocity of about 6000 m/sec or more, i.e. higher than other materials of other components of the land vehicle. Shock waves encounter less resistance in high-acoustic velocity materials and are thus conducted laterally outwardly, i.e. away from the body. The shock wave guide members may be located immediately above bottom runs of tracks (12) and annularly within wells of bogey wheels (14) of track vehicles; and annularly around hubs or within tyres of wheels of wheeled vehicles.Type: GrantFiled: May 26, 2004Date of Patent: June 8, 2010Assignee: CSIRInventor: Vernon P.

Publication number: 20090263902Abstract: A method for regulating expression of a virulence gene of Agrobacterium is described. The method comprises the steps of stimulating cereal cells, such as sorghum, so as to produce an active, typically phenolic, compound and exposing the Agrobacterium to this compound.
