Andreas Graichen, Norrkoping SE
| Patent application number | Description | Published |
|---|---|---|
| 20090134136 | Apparatus and method to machine holes - The present invention relates to an apparatus for machining holes, especially to machine holes in a surface of a coated gas turbine airfoil, which apparatus comprises a laser device for laser drilling and an electrode for electrical discharge machining. Further the invention relates to a method to machine a hole into a coated surface with an apparatus of the incipiently mentioned type. Known methods make use of a machine with separate machine heads for laser drilling and electrical discharge machining. By combining these two devices in one machine head the invention gives the possibility to save time and obtain very accurate results. | 05-28-2009 |
| 20100287754 | Repair of a stationary rotor seal - A method and an apparatus for mobile repair of a stationary rotor seals of a turbo machine is provided. The method includes the following steps, 3D-scanning of the stationary seal, generation of 3D-model of the stationary seal, removing of the damaged spots of the seal using laser cutting, and generating a new seal at the repair spot by use of a second process head, which generates the seal by laser powder cladding. The apparatus includes a 3D-scanner, a cutting tool, and a first process head and a second process head. | 11-18-2010 |

| 20090202498 | DIRECT DIFFERENTIATION OF CARDIOMYOCYTES FROM HUMAN EMBRYONIC STEM CELLS - The present invention relates to the induction of differentiation in stem cells to cardiomyocytes and factors such as prostaglandin alone or in combination with other factors including essential minerals selected from the group including transferrin and selenium, small molecules selected from the group including a p38 MAPK inhibitor such as SB203580 and protein growth factors of the FGF, IGF and BMP families such as but not limited to IGF1, FGF2, BMP2, BMP4 and BMP6. and insulin that influence the process of differentiation to cardiomyocytes. Media that is appropriate for the induction of differentiation of cardiomyocytes from stem cells is also provided wherein the media contains these factors. The use of cardiomyocytes and cardiac progenitors produced by the directed differentiation in transplantation and screening for cardiac compounds is also provided. | 08-13-2009 |
