Patent CA-2301506-A1 (CA)
Inventor: ANDERSEN SOREN
IPC: F03D1/06
Filed: 1998-09-04
Abstract: With conventional windmills the wing blades used have a certain resilient flexability which, in connection with "front runners", implies that the wings in strong wind are bent inwardly towards the mill tower, i.e. the wing rotor should be placed with a required safety spacing from the mill tower. An associated forward displacement of the entire rotor involves high costs and has already been avoided in various unsuccessful manners. The invention provides for an improved solution of the problem in disclosing that the wing blades, per se, are designated with such a forwardly curved configuration that the wing tips, when the wings are mounted in a conventional manner on the wing hub, will be located with increased spacing from the side of the tower.

Title: Method for inverting the convex configuration of a liquid-product storage-tank bottom
Inventor: WITTER ALDYR
IPC: B65D88/08
Filed: 1998-09-08
Abstract: This invention relates to a method for inverting the convex configuration of a liquid-product storage-tank bottom with a view to providing greater efficiency in the operations of removing the undesirable materials which normally accumulate in the tank bottom (5). A layer of material having, plastic properties, is placed over the conventional tank bottom (7), except for one part from the centre of the tank base to the edges. The material with plastic properties hardens over time, thus producing a new bottom (7) whose centre (11) is at a level below the level of the edges. The part over which material having plastic properties was not placed forms a flow gutter (9) which leads the liquids and sediments which have to be drained off to the edges.

Title: Ifnar2/ifn complex
Inventor: CUNNINGHAM MARK
IPC: C12P21/04
Filed: 1998-12-18
Abstract: The in vivo effect of Type I interferon (IFN) can be prolonged by administering the interferon in the form of a complex with an IFN binding chain of the human interferon .alpha./.beta. receptor (IFNAR).  Such a complex also improves the stability of the IFN and enhances the potency of the IFN. The complex may be a non-covalent complex or one in which the IFN and the IFNAR are bound by a covalent bond or a peptide. When bound by a peptide bond in the form of a fusion protein, the IFN may be separated from the IFNAR by means of a peptide linker. Such a fusion protein may be produced by recombinant DNA  technology. Storing IFN in the form of such a complex improves the storage life of the IFN and permits storage under milder conditions than would otherwise be possible.
