Patents by Inventor Erik Meyer

Erik Meyer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9909118
    Abstract: This invention provides compositions and methods for rapid separation, isolation and purification of nucleic acids from biological samples using anionic exchange media. The method can utilize commercially available strong or weak anion exchanger materials with selected solutions of known ionic strength for adsorption and elution. The instant method is particularly advantageous as it permits the purification and identification of shorter fragments of nucleic acids from bodily fluids which, until now, had not been identified.
    Type: Grant

  • Patent number: 9644688
    Abstract: A clutch for an automatic transmission for a motor vehicle includes a clutch housing and a retaining ring. In an inner circumferential surface of the clutch housing concentrically at a central axis (M) of the cylinder jacket-shaped inner circumferential surface, a ring groove that is open radially inward is formed, within which the retaining ring is arranged. The retaining ring is thereby open and features two spaced ends. In the area of the ring groove, at least one stop is formed, whereas a distance between the ends from each other or the position of the stop is selected in such a manner that, in the assembled state, only one end of the retaining ring may come into contact with a stop, while the other end is spaced from this stop or an additional stop.

  • Patent number: 9163229
    Abstract: This invention provides compositions and methods for rapid isolation and purification of nucleopolymers from biological samples using anionic exchange media. The method of this invention can utilize commercially available anion exchanger materials with selected solutions of known ionic strength for absorption and elution. The medium/nucleoprotein bound complex may be optionally stored or transported, and is subsequently treated with eluents to remove undesirable proteins and inorganic salts. The partially purified complex may also be stored or transported. This method is particularly advantageous since it allows rapid isolation and purification of soluble nucleic acids from a large volume of biological fluids with easy handling and storage, stabilizing the samples against degradation prior to analysis. It also permits the purification and identification of shorter fragments of nucleic acids from bodily fluids which, until now, had not been identified.

  • Publication number: 20080139801
    Abstract: This invention provides compositions and methods for rapid separation, isolation and purification of nucleopolymers, especially nucleic acids, from biological samples using anionic exchange media. The method of the present invention can utilize commercially available strong or weak anion exchanger materials with selected solutions of known ionic strength for adsorption and elution. The medium/nucleoprotein bound complex may be optionally stored or transported, but is subsequently treated with appropriate eluents to remove any undesirable proteins, including destabilizing enzymes, and inorganic salts and the like. The partially purified complex may also be stored or transported prior to further processing.

  • Patent number: 6793581
    Abstract: A constant velocity joint for use with an automotive vehicle. The constant velocity joint includes an outer race and an inner race supported within the outer race. The constant velocity joint includes a cover, wherein that cover creates a barrier between a lubricant and the atmosphere. The constant velocity joint also includes a permeable membrane adjacent to the cover.
