| 20080268758 | Height adjustable drive arrangement for a floor care machine - A floor care machine such as a floor polisher includes a machine frame carrying a motor coupled through a drive arrangement to a rotationally driven head on which a floor care disc such as a polishing pad is mounted. The drive arrangement includes a drive element rotationally driven by the motor, and a driven element that is connected to the driven head and is automatically height adjustable. The drive element includes a bearing hub, an outer ring and four uniformly rotationally offset spokes that carry first rolling guides extending along helical paths about the rotation axis. The driven element includes upper and lower partial elements that receive the spokes therebetween and carry second rolling guides arranged facing the first rolling guides along the helical paths, and roller bodies are interposed therebetween. Relative rotation between the drive element and the driven element causes an axial height adjustment of the driven head. | 10-30-2008 |
| 20100125966 | Floor care disk - A floor care disk for a floor care machine such as a floor polishing machine includes a floor care pad mounted on a drive plate. The drive plate includes a stiff disk element and tongue-like tabs connected flexibly to a radially outer portion or rim of the disk element, and extending radially inwardly toward a radially inner portion or hub of the disk element. The radially inner free ends of the tongue-like tabs are free to flexibly deflect away from the plane of the disk element. The pad is mounted on the tabs and on the radially outer portion of the disk element. During rotational operation of the floor care disk, due to the arising centrifugal force acting on the center of mass of the rotating pad and tongue-like tabs, the pad and the tongue-like tabs are flexibly deflected away from the disk element and toward the floor surface, thereby deflecting the pad into osculating contact with the floor surface. | 05-27-2010 |
| 20110232024 | Arrangement of a Motor Protection Filter in a Vacuum Cleaner - A vacuum cleaner has a lid that selectively opens or closes a filter bag compartment. A secondary motor protection filter is removably mounted in the lid by a frame of an elastic material that simultaneously seals the secondary filter element to the lid and seals the lid onto the bag compartment. An air passage flows between the secondary filter and the lid through a duct to the suction motor compartment. A perimeter groove in the lid receives a spline of the elastic frame of the filter element in a removable manner, while the opposite surface of the frame forms the seal surface relative to a housing rim around the bag compartment. | 09-29-2011 |
| 20110232025 | Arrangement for Positioning and Holding a Filter Bag in a Vacuum Cleaner - A filter bag of a vacuum cleaner has a filter mounting plate that includes a generally strap-shaped securing element with pivot members on an end thereof. A housing of the vacuum cleaner defines a filter bag compartment therein and has pivot receivers into which the pivot members can be substantially vertically inserted. Then the filter mounting plate can be pivoted into a substantially horizontal installed position as the filter bag is inserted into the filter bag compartment. In the installed position, a first stop member of the filter mounting plate contacts and is stopped by a second stop member of the housing so as to prevent further pivoting and so as to properly position and hold the filter mounting plate. | 09-29-2011 |

| 20100318472 | BETA-TARGETED INVESTMENT FUND - A beta-targeted portfolio is managed by receiving historical beta information regarding a plurality of stocks, and transforming the historical beta information regarding the plurality of stocks into a purchasing decision regarding at least one of the plurality of stocks based on the at least one stock's anticipated future beta. Selected stocks having approximately a desired anticipated future beta matching a desired beta of the portfolio are purchased to form a beta-targeted portfolio. | 12-16-2010 |

| 20110288703 | METHOD FOR OPERATING A HYBRID DRIVE DEVICE OF A MOTOR VEHICLE AND HYBRID DRIVE DEVICE AND ELECTRONIC CONTROL UNIT - In a method for operating a hybrid drive device of a motor vehicle, which has at least two different drive assemblies, especially an electric machine and an internal combustion engine, that are able to be connected to at least two drive trains of the motor vehicle, during the reconnecting of one of the drive assemblies, particularly from a first to a second of the drive trains, or from the second to the first drive train, and/or during a synchronization, a replacement torque substantially corresponding to the torque produced by the one drive assembly is able to be provided by an additional one of the drive assemblies by the at least partial closing of a clutch. | 11-24-2011 |

| 20090098660 | Method for the Purification of Antibodies - A method for the purification of immunoglobulins by ion exchange chromatography is described. The chromatographic method uses a weak ion exchange resin and a single step elution process for the purification of an immunoglobulin. Additionally a method for the determination of the salt concentration for the single step elution of an immunoglobulin from an ion exchange resin is described. | 04-16-2009 |
| 20090143288 | Peptide-complement conjugates - The current invention reports a polypeptide conjugate, wherein the conjugate comprises a first polypeptide selected from the group of polypeptides comprising SEQ ID NO: 01 and fragments thereof, and a second polypeptide selected from the group of antifusogenic peptides. | 06-04-2009 |
| 20110034672 | PURIFICATION OF NOT-GLYCOSYLATED POLYPEPTIDES - The current invention reports a method for the purification of a not-glycosylated, heterologous polypeptide, which has been recombinantly produced in a prokaryotic cell, wherein the method comprises three chromatography steps of which the first chromatography step selected from i) hydrophobic charge induction chromatography, or ii) hydrophobic interaction chromatography, or iii) affinity chromatography, or iv) ion exchange chromatography, the second chromatography step is selected from i) anion exchange chromatography, or ii) cation exchange chromatography, or iii) hydroxylapatite chromatography, or iv) hydrophobic interaction chromatography, and the a third chromatography step is selected from i) hydrophobic charge induction chromatography, or ii) anion exchange chromatography, or iii) cation exchange chromatography, or iv) hydrophobic interaction chromatography, whereby the first chromatography step is an affinity chromatography in case of polypeptides capable of interacting with metal ligands, the second chromatography step is not a hydroxylapatite chromatography step in case of polypeptides with an isoelectric point below 6.0, and the third chromatography step can be performed in flow-through mode with polypeptides having a low or high isoelectric point. | 02-10-2011 |
