20090212188 | SUSPENSION SYSTEM FOR A CEILING MOUNT OF A SURGICAL MICROSCOPE - A suspension system for a ceiling mount of a medical device is suggested, comprising an attachment device provided at a ceiling and a console arranged between the attachment device and the ceiling mount for movement of the ceiling mount parallel to the ceiling. Said console comprises a support plate connected to the attachment device and a carriage that is movable with respect to the support plate and is connected to the ceiling mount. This allows movement of the medical device to the greatest extent possible to all positions in the surgical area without colliding with alternately usable operating lights. | 08-27-2009 |
20090218455 | BALANCING APPARATUS FOR A SURGICAL MICROSCOPE - A balancing apparatus for a surgical microscope is suggested balancing an optics carrier with and without a microscope holder holding the surgical microscope and with and without add-on units. The optics carrier is connected via a pivot support to a stand and rotatable around a first rotational axis in relation to the pivot support. The balancing apparatus comprises a Y displacement unit comprising a first slide for displacement of the optics carrier in a Y direction; and a Z displacement unit comprising a second slide for displacement of the optics carrier in a Z direction. The weight of the second slide acts as a compensation weight for compensating the weight of the optics carrier with and without the microscope holder holding the surgical microscope and with and without the add-on units. | 09-03-2009 |
20090218456 | STAND FOR A SURGICAL MICROSCOPE - A stand for a surgical microscope is suggested, comprising a vertical support, at least one horizontal support, a first vertical articulation unit that is connected the horizontal support, a second articulation unit determining an oblique pivot axis, a displacement unit that is attached to the second articulation unit and has multiple degrees of freedom for displacement and balancing of an optics carrier carrying the surgical microscope, at least one pivot support encompassed by the displacement unit, and means for displacing the optics carrier in an X direction extending horizontally and transversely to the oblique pivot axis. The pivot support comprises a pivotable parallelogram support and a holding arm that is attached to the pivotable parallelogram support and is configured such that it simultaneously serves as a means for displacing the optics carrier in the X direction. | 09-03-2009 |
20110147563 | VIBRATION DAMPING OF A CEILING MOUNT CARRYING A SURGICAL MICROSCOPE - The present invention relates to a ceiling mount for a surgical microscope, including at least two load-bearing sections joined together by a damping interface, said interface including at least two damping layers which are made of damping material and are separated from each other by a bracket plate made of non-damping material. In order to damp a wider spectrum of mechanical disturbances even more efficiently, the material of one damping layer has other elastic properties than the material of the other damping layer. | 06-23-2011 |
20110290960 | STAND FOR A SURGICAL MICROSCOPE WITH A PARALLELOGRAM SUPPORT AND A DISPLACEMENT SCREW - A stand for a surgical microscope is suggested that is provided with vertical and horizontal supports, articulation units and a displacer for displacing the optics carrier in an X direction extending horizontally and transversely to an oblique pivot axis. The displacer has a pivot support provided with a pivotable parallelogram support and a holding arm that is attached to the pivotable parallelogram support and is configured such that it simultaneously serves as a displacer for displacing the optics carrier in the X direction. The pivot support is provided with an additional displacement unit that determines the position of the parallelogram support with reference to the second articulation unit and the additional displacement unit contains a displacement screw that protrudes through the parallelogram support and is connected in an articulated fashion at one of its ends to a displacement element mounted to the parallelogram support. | 12-01-2011 |
20110297800 | STAND FOR A SURGICAL MICROSCOPE WITH A PARALLELOGRAM SUPPORT DRIVEN BY AN ENERGY STORING DEVICE - A stand for a surgical microscope is suggested that is provided with vertical and horizontal supports; articulation units; and a displacement unit that is attached to one of the articulation units. At least one pivot support is provided and encompassed by the displacement unit. A displacer is provided at the pivot support. The pivot support has a pivotable parallelogram support that is provided with a spring or a gas damper as energy storing device that interconnects and supports movement of the movable parts in the interior of the parallelogram support assisting with a stored force in a displacement movement. A holding arm is attached to the pivotable parallelogram support and simultaneously serves for displacing the optics carrier in the X direction. | 12-08-2011 |

20090069594 | Process and Catalyst for Oxidizing Aromatic Compounds - Catalytic compositions for conversion of substituted aromatic feed materials to oxidized products comprising aromatic carboxylic acid derivatives of the substituted aromatic feed materials comprise at least two metal or metalloid elements, at least one of which is palladium, platinum, vanadium or titanium, and at least one of which is a Group 5, 6, 14 or 15 metal or metalloid. A process for oxidizing substituted aromatic feed materials comprises contacting the feed material with oxygen in the presence of such a catalytic composition in a liquid reaction mixture. | 03-12-2009 |
20090088585 | Process and Catalyst for Oxidizing Aromatic Compounds - Catalytic compositions for conversion of substituted aromatic feed materials to oxidized products comprising aromatic carboxylic acid derivatives of the substituted aromatic feed materials comprise a combination comprising a palladium component, an antimony component and/or a bismuth component, and one or more Group 4, 5, 6 or 14 metal or metalloid components. A process for oxidizing substituted aromatic feed materials comprises contacting the feed material with oxygen in the presence of such a catalytic composition in a liquid reaction mixture. | 04-02-2009 |
20090118536 | Process for the Production of Aromatic Carboxylic Acids in Water - A process is disclosed for producing at least one aromatic carboxylic acid by contacting a liquid reaction mixture comprising an aromatic feedstock and water with oxygen in the presence of a bromine-free metal catalyst composition wherein the metal catalyst composition has activity in the absence of bromine for oxidation of the aromatic feedstock with at least 80% conversion to oxidized aromatic derivatives of the aromatic feedstock and with at least 80% selectivity to the aromatic carboxylic acid. This process operates in water without the use of bromine at temperatures and residence times substantially the same as conventional processes for aromatic carboxylic acid manufacture, as well as with less total burning and with yields to product equivalent or higher than conventional processes. | 05-07-2009 |
