20090240020	Polyether ketone, its monomer and its phenolate - A process for the preparation of an alkali metal salt of 4-chloro-4′-hydroxy benzophenone including the steps of (a) preparing purified 4-chloro-4′-hydroxy benzophenone by a process including distilling under reduced pressure a liquid containing 4-chloro-4′-hydroxy benzophenone and a solvent selected from diphenyl sulphone, diphenylene sulphone, benzophenone and dichlorobenzophenone, and then (b) preparing the alkali metal salt of thus purified 4-chloro-4′-hydroxy benzophenone by the reaction of the purified 4-chloro-4′-hydroxy benzophenone with a stoichiometric excess of at least one alkali metal base. There is also described a polymerization process using the alkali metal salt to yield PEK with high inherent viscosity and improved mechanical and thermal properties.	09-24-2009

20110230812	METHOD AND DEVICE FOR RECOGNITION OF PARAVASAL BLEEDING - A method and a device for recognition of paravasal bleeding upon a supplying of blood to a vascular access via a line and/or upon the removal of blood from a vascular access via a line, particularly paravasal bleeding during extra-corporeal blood treatment, such as for hemodialysis, hemofiltration or hemodiafiltration is provided. A device for extra-corporeal blood treatment, particularly for hemodialysis, hemofiltration or hemodiafiltration, comprising a device for recognition of paravasal bleeding is also provided. The method and the device are based on the change of arterial pressure in the arterial branch or the venous pressure in the venous branch of the extra-corporeal circuit being registered during the extra-corporeal blood treatment. If paravasal bleeding occurs during the blood treatment, the positive dynamic pressure on the line leading to the vascular access rises on the venous cannula during the extra-corporeal blood treatment, or the suction pressure on the line leaving the vascular access, such as the arterial cannula during extra-corporeal blood treatment, rises; that is, the suction pressure becomes more negative. The pressure rise begins moderately at first and then becomes increasingly greater. Decisive for the method and the device, therefore, is that pressure changes that come from a pressure level exhibiting a large difference from the reference value find stronger consideration than those that come from a pressure level that exhibits only a minor difference from the reference value.	09-22-2011
