Title: Method and system for handling radio signals in a radio base station
Inventor: KARLSSON JONAS
IPC: H04W16/28
Filed: 1999-03-30
Abstract: A radiocommunication system is described wherein a flexible transceiver (400) is provided that can be switchably connected to different antenna structures (450, 460). Switching matrices (490) are provided between the antenna elements and the receive processing circuitry (420) which, under the control of the central processing unit (430), allows the transceiver to handle the different antenna structures.

Title: Stretch wrap film
Inventor: GENNESSON PATRICK
IPC: B29C55/06
Filed: 2001-02-06
Abstract: A method of making a plastics stretch film comprises the steps of taking a cast or blown film of LLDPE at a temperature of between 50°C and 100°C, stretching it in two successive stretching steps, the first step having a stretch ratio higher than that of the second step, to cause both plastic and elastic deformation of the film. The film is then relaxed to substantially release all of the elastic deformation and winding the substantially relaxed film into rolls. Preferably, the first stretch ratio is in the range 1:1.70 to 1:1.80 and the second stretch ratio is in the range 1:1.85 to 1:1.95, and there is a reduction ratio of substantially 1:0.85 between the speed of the film during the second stretch rolling step and the speed of the film during wind-up.

Title: Method for treatment of .beta.-hemoglobinopathies
Inventor: BOHMER RALPH M
IPC: A61K35/18
Filed: 2000-08-18
Abstract: The present invention provides a method for ameliorating .beta.-globin disorders in a mammal. In one aspect of the invention, the treatment involves ex vivo treatment of early erythroid progenitor cells that leads to an increase in the relative amounts of cells subsequently expressing and accumulating HbF. The cell treatment is to be followed by transplantation of the modified cells. In another aspect of the invention, the same modification of progenitor cells occurs in vivo. Both treatments are based on the novel discovery that the modification can be performed very early in the erythroid maturation process, without disturbance of the subsequent proliferation and maturation of the erythroid precursor. The present invention also provides a procedure for the monitoring of .beta.-globinopathies and the response of a patient to treatment. In this aspect of the invention, erythropoiesis of a patient is studied (in vivo or in vitro) by generating profiles of correlated contents of different types of hemoglobin present in nucleated red cells.
