IPC: H01M14/00
Filed: 2003-01-14
Abstract: The invention relates to a titanium oxide-based polymer composition. The inventive composition comprises a TiOx(OH)y(H2O)z(x+y−+z=3) titanium oxide-based polymer in the form of a gel or sol. Said polymer, which has a one-dimensional (1D) structure, is made from concentrically-wound fibers having a periodicity which is deduced from the spacing between said fibers, of between 3.5 Å and 4 Å. Each fiber comprises TiO6octahedrons and each TiO6octahedron shares two opposite edges with two adjacent octahedrons (2.times.2.92 Å) in order to form infinite chains which develop along the axis of a fiber. According to the invention, two adjacent chains form double lines as a result of the shared edges (2.times.3.27 Å). The inventive polymer is suitable for use as a photosensitive element in a photovoltaic cell, such as a sunscreen for a window.

IPC: B65D5/42
Filed: 2003-02-07
Abstract: A carton of the wrap-around type has a pair of overlapped base panels (12,20). One of the bases panels (12) which carries a locking tab (38) overlies a tongue (42) protruding from the end edge of the other base panel (20). The protruding tongue (42) is formed with a complementary locking aperture (40) engaged by the locking tab (38) to secure the overlapped panels (12, 20) together. On either side of the locking tab (38), the said one base panel (12) has a hinged tab (50, 52) protruding from the end edge of that panel. Each of the hinged tabs underlies the end edge (44,46) of the other base panel (20), one on each side of the protruding tongue (42). This `over and under' arrangement presents less of an externally overlapped edge than is the case of a simple complete overlap and thus mitigates against the base panels being skewed or prized apart leading to tearing and/or dislodgment of the locking means.
