  • Patent number: 7730822
    Abstract: 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.

  • Patent number: 7700335
    Abstract: A process for producing enzymes structures includes providing an emulsion of droplets of a first liquid phase dispersed in a second liquid phase. The one liquid phase is a hydrophilic phase, while the other liquid phase is a hydrophobic phase which is immiscible with the hydrophilic phase. Enzyme molecules are located at or within interfacial boundaries of the droplets and the second liquid phase. The enzyme molecules of the respective droplets are cross-linked so that individual enzyme structures, which are stable and in which the enzymes are immobilized with a majority of active sites of the enzymes being orientated either internally or externally, are formed from individual droplets.

  • Patent number: 7641917
    Abstract: The invention provides a method of encapsulating an active substance in an interpolymer complex, to make an encapsulated product in particulate form. The method comprises forming a mixture of a supercritical fluid, an interpolymer complex and an active substance and then causing or allowing the interpolymer complex to encapsulate the active substance. The encapsulated product is then separated from the supercritical fluid and, if necessary, the product is subjected to size reduction to ontain particles in which the active substance is encapsulated by the interpolymer complex.

  • Publication number: 20090263902
    Abstract: 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. The compound induces expression of the virulence gene of the Agrobacterium, effecting T-DNA transfer from the Agrobacterium to the cereal cells, which are thereby transformed.

  • Publication number: 20090214302
    Abstract: One aspect of the invention concerns a method of controlling a flow of slurry pumped through a non-vertical pipeline (10) by a pump (54). In the method, at least one sensor (12) is provided. This has a sensing face (42), and the sensor is mounted at a predetermined position along the length of the pipeline such that the sensing face is flush with the invert of the pipeline at that position. The sensor is calibrated to provide output signals related to the velocity of the slurry at the invert. The operation of the pump and/or the density of the slurry are then controlled in response to the output signals from the sensor. Other aspects of the invention relate to the apparatus and to a slurry pipeline control system incorporating the apparatus and in which the method is implemented.
