  • Patent number: 10076784
    Abstract: A liquid containing receptacle having a filter is disclosed that in one form includes a nozzle. The filter includes a passage having a portion with a size that restricts the flow of a liquid there through unless sufficient pressure is applied to overcome a liquid and filter property such as surface tension. The pressure in the liquid at the filter can be varied by changing a gas overpressure above a surface of the liquid, changing a head height of the liquid, and/or changing the liquid and filter property, among possible others. In one embodiment the liquid containing receptacle can be used to contain a molten metal that is used in an investment casting mold. The molten metal can be selectively poured into a mold by selectively changing pressure of the molten metal at the filter or by changing the pressure at which molten metal flows through the filter.

  • Patent number: 9963788
    Abstract: The underlying invention consists in an acidic aqueous concentrate that is based on a mixture of water-soluble compounds of the elements Zr and/or Ti, organosilanes and dispersed silicates suitable for the preparation of a conversion treatment solution. The invention thereby establishes a shelf stable (1K) product useful for the surface treatment industry. Such a (1K) product has not only the advantage of being easily converted into a working composition through dilution with water, but the working compositions themselves that originate from the (1K) product do confer superior corrosion resistance to metal substrates when used in a process for the conversion coating treatment. A conversion treatment solution obtainable from the acidic aqueous concentrate as well as a process for the corrosion-resistant treatment of metal surfaces are thus further objects of this invention.

  • Patent number: 9915006
    Abstract: A production method of a member having a surface provided thereon with a chemical conversion coating includes a contacting step and a washing step. The contacting step causes a reactive-type chemical conversion treating acidic composition to contact with a base material having a metal-based surface thereby forming a chemical conversion coating on the metal-based surface of the base material. The washing step washes the base material having been subjected to the contacting step to obtain a member having a surface provided thereon with the chemical conversion coating. The reactive-type chemical conversion treating acidic composition contains a water-soluble trivalent chromium-containing substance, a water-soluble titanium-containing substance, and a carboxylic acid compound. The acidic composition is free from a water-soluble cobalt-containing substance.
