  • Patent number: RE47092
    Abstract: An oxygen emitter which is an electrolytic cell is disclosed. When the anode and cathode are separated by a critical distance, very small microbubbles and nanobubbles of oxygen are generated. The very small oxygen bubbles remain in suspension, forming a solution supersaturated in oxygen. A flow-through model for oxygenating flowing water is disclosed. The use of supersaturated water for enhancing the growth of plants is disclosed. Methods for applying supersaturated water to plants manually, by drip irrigation or in hydroponic culture are described. The treatment of waste water by raising the dissolved oxygen with the use of an oxygen emitter is disclosed.

  • Patent number: RE47174
    Abstract: The invention relates to a filter unit for filtering gaseous fluids, comprising a filter insert part with a filter medium and a sealing element, said element being clamped between sealing struts on parts of the filter housing. The clamping force produced by the sealing struts that lie opposite one another runs at least approximately perpendicularly to the mounting direction of the housing parts.

  • Patent number: RE47483
    Abstract: A nanoimprint lithography template including, inter alia, a body having first and second opposed sides with a first surface disposed on the first side, the second side having a recess disposed therein, the body having first and second regions with the second region surrounding the first region and the recess in superimposition with the first region, with a portion of the first surface in superimposition with the first region being spaced-apart from the second side a first distance and a portion of the first surface in superimposition with the second region being spaced-apart from the second side a second distance, with the second distance being greater than the first distance; and a mold disposed on the first side of the body in superimposition a portion of the first region.

  • Patent number: RE47582
    Abstract: A free radical sterilization system having a chamber defining a region, and a generator for generating free radical reach effluent from a free radical electric generator and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the electric generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The free-radical sterilization system is used in sterilizing items in the chamber and, with an open-bottomed wound chamber, in treating wounds on a body.

  • Patent number: RE47630
    Abstract: An approach for forming a semiconductor device is provided. In general, the device is formed by providing a metal layer, a cap layer over the metal layer, and an ultra low k layer over the cap layer. A via is then formed through the ultra low k layer and the cap layer. Once the via is formed, a barrier layer (e.g., cobalt (Co), tantalum (Ta), cobalt-tungsten-phosphide (CoWP), or other metal capable of acting as a copper (CU) diffusion barrier) is selectively applied to a bottom surface of the via. A liner layer (e.g., manganese (MN) or aluminum (AL)) is then applied to a set of sidewalls of the via. The via may then be filled with a subsequent metal layer (with or without a seed layer), and the device may the then be further processed (e.g., annealed).
