Abstract: Radioactive grafts or cuffs are made by incorporating radioactive elements into a pliable material such as ePTFE. The radioactive grafts or cuffs are placed into the body to prevent the proliferation of malignant cells. For example, a graft or cuff may be used in an occluded lumen after it has been opened to prevent subsequent restenosis. While the grafts are used primarily  for implantation inside a body lumen, the cuffs can be used in a variety of locations including being wrapped around the outside of an affected vessel. Some embodiments of the present invention incorporate radioactive seeds into  ePTFE grafts. The radioisotopes comprising the seeds are chosen according to  their radioactive properties and are mixed with the PTFE prior to extrusion.  Following extrusion, the PTFE is expanded and sintered to yield a final product.

Title: Transgenic trees exhibiting increased growth, biomass production and xylem fibre length, and methods for their production
Inventor: MORITZ THOMAS
IPC: C12N5/10
Filed: 2001-03-02
Abstract: Important aims in nearly all tree-breeding programs around the world are to produce plants with increased growth rates and stem volumes, and shorter rotation times. Such trees would yield more biomass per area unit. Here the present inventors have shown that when over-expressing a key regulatory gene in the biosynthesis of the plant hormone gibberellin (GA) in hybrid aspen (Populus tremula x P. tremuloides), improvements in valuable traits such as growth rate and biomass are obtained. In addition, these trees also have longer xylem fibers than unmodified wild type plants.  Long fibres are very desirable in the production of strong paper, but it has not (as yet) proved possible to influence this trait by traditional breeding techniques. A further advantage of the present invention is that it may reduce or eliminate the use of growth influencing chemicals in forestry.

Title: Stabilizer for cantilevered tire building drum
Inventor: CORNET FRANCIS
IPC: B29D30/00
Filed: 2002-09-16
Abstract: Method and apparatus for stabilizing a tire building drum (120, 220, 320), wherein the tire building drum has two ends, is permanently supported at a single cantilever support end (125), and the remaining end is a free end (123, 223). The method comprises providing a free end support (140, 240, 340) engaged with the free end to stabilize the tire building drum by restricting lateral movement of the free end; and freeing the free end by temporarily retracting the free end support when desired, e.g., to enable application of annular tire components on the tire building drum (120, 220, 320), or to enable removal of a built tire from the tire building drum. Preferably, the free end support allows rotation of the tire building drum while the free end support is engaged with the free end. A preferred embodiment uses overtravel of actuator linkages stopped against an extension stop to lock the free end support in place, engaged with the free end, to stabilize the tire building drum without requiring continued power input.

Filed: 2002-09-30
Abstract: In order to carry out actions such as setting up a call from an entity in the address roalm of one middlebox to an entity in the address realm of another middlebox, then a middlebox control node such as a call server is used. Previously, the middlebox control node has needed to have pre-configured information about all the previously and which address roalms they are associated with. The present invention provides one or mere middlebox-identity-providing nodes which are separate from the middlebox control node, and which more directly connected to the end users of the service than the middlebox control nude. This provides greater flexibility in network design and removes the need for middlebox information to be pre-configured at the middlebox control node. Instead, this information is sent to the middlebox control node, as part of signalling messages, from middlebox-identity-providing nodes.
