| 20090275818 | APPARATUS AND SYSTEM FOR INSERTION OF AN IMPLANT - The present invention provides an apparatus for insertion of a flexible implant into a body section of an implant recipient, the apparatus comprising an elongate guiding section having a longitudinal axis and an inner volume for removably receiving the implant, an elongate first receiving member connected at its first end to a first actuator arranged for moving the first receiving member within the guiding section in parallel to the axis of the guiding section, a first control device for controlling the actuation of the first actuator, wherein first receiving member at its second end opposite its first end carries a gripping unit for releasably gripping a proximal end of the implant, a second actuator for controlling the configuration of the implant, and a second control device for controlling the actuation of the second actuator. | 11-05-2009 |
| 20090258870 | NOVEL ANSAMITOCIN DERIVATIVES - Provided are among other things ansamitocin derivatives, pharmaceutical compositions comprising these novel ansamitocin derivatives, methods for the production of the ansamitocin derivatives and their use for the treatment of cancer. | 10-15-2009 |
| 20090201967 | LASER DEVICE COMPRISING A DIFFRACTION GRATING AND COUPLED LASER RESONATORS - The present invention provides a laser device wherein one diffraction grating and at least two reflectors are arranged such that two coupled resonators are formed for the light path. This laser device is an arrangement forming a first optical resonator comprising a first and a second reflector including in its light path the diffraction by the grating. The second reflector is arranged perpendicularly to an order of diffraction of the grating. Coupled with the first resonator (A), there is provided a second mirror-reflective resonator between a mirror-reflective surface of the grating and the second reflector. In the case of the grating having an even number of ports, the second resonator needs completion by a third reflector arranged to reflect light from specular reflection by the grating back to the grating. For gratings having an odd number of ports, the second reflector is arranged in parallel to the grating. The laser medium is preferably arranged between the first reflector and the grating. | 08-13-2009 |
| 20090108239 | COMPOSITE MEMBRANE - The present invention relates to composite ceramic membranes for use in chemical processes such as the separation of molecules, sometimes referred to as molecular sieving, preferably in combination with chemical conversion of molecules selected from a composition of different molecules, e.g. the selective partial or full oxidation. The composite membrane of the invention offers a combination of molecular sieving and oxygen transport that makes the composite membrane suitable for the selective oxidation of hydrocarbons from a feed comprising a mixture hydrocarbons. The composite membrane of the invention comprises a first layer containing an oxygen transporting material (OTM), e.g. perovskite, and, in association with the first layer, a second layer, containing a molecular sieve layer, e.g. a zeolite. | 04-30-2009 |
