  • Patent number: 6814783
    Abstract: Inorganic, porous particles filter a substance or substances from a flow of fluid such as a gas. The particles can be arranged into a bed to filter a substance (filtrate substance) from a fluid. The filtrate substance can collect on or within the pores of the inorganic particles. Collection of the filtrate substance within the pores of the particles rather than within the interstices of the bed enhances the filtering capacity and does not impede the flow of fluid through the bed of particles. Furthermore, the inorganic particles are re-usable, in that they can be subjected to harsh filtrate-separation techniques, e.g., heat treatment, solvent extraction, detergent washing, and centrifugal separation, yet retain their desired properties.

  • Patent number: 6814788
    Abstract: Vacuum cleaner with water filter constituted by an aspirator connected to an air inlet conduit controllable by an operator, and by a filtering chamber interposed between the conduit and the aspirator. The filtering chamber has in its own lower portion a tank for containing the water and dirt. Above the maximum level of filling of the containment tank the filtering chamber also has a first air inlet section connected to the inlet conduit, and an air outlet section connected to the aspirator. The filtering chamber further comprise at least a second air inlet section. The aspirator is also provided with first means for spraying the water contained in the containment tank towards the main path of the air that goes from the first inlet section to the outlet section, associated to the first inlet section, and second means for spraying the water contained in the containment onto the air flowing along the main path, and operatively connected to the second inlet section.

  • Patent number: 6814794
    Abstract: Temporary dental cements used to temporarily affix a dental prosthesis or appliance to a tooth or other dental substrate includes one or more soothing agent to prevent or reduce tooth sensitivity. The temporary dental cement includes a mixture of an ion leaching agent, polycarboxylic acid, a soothing agent and water. The soothing agent (e.g., 2-ethoxybenzoic acid and 2-methoxy-4-methylphenol) is added in an amount so as to reduce or eliminate tooth sensitivity associated with the reaction between the polycarboxylic and the ion leaching agent (base). The temporary cement composition is sufficiently hydrophilic that it can be readily removed from the tooth when it is desired to permanently restore the tooth.

  • Patent number: 6814801
    Abstract: A method is disclosed for producing high quality semi-insulating silicon carbide crystals in the absence of relevant amounts of deep level trapping elements. The invention includes the steps of heating a silicon carbide crystal having a first concentration of point defect related deep level states to a temperature above the temperatures required for CVD growth of silicon carbide from source gases, but less than the sublimation temperature of silicon carbide under the ambient conditions to thereby thermodynamically increase the number of point defects and resulting states in the crystal, and then cooling the heated crystal to approach room temperature at a sufficiently rapid rate to maintain a concentration of point defects in the cooled crystal that remains greater than the first concentration.
