  • Patent number: 10807896
    Abstract: A process and apparatus for manufacturing glass. A mixture of solid glass-forming materials comprising at least one fining agent are introduced into a doghouse located upstream of an elongated tank. The glass-forming materials are melted in the doghouse at a temperature at or above a fining-onset temperature of the at least one fining agent by application of heat from one or more submerged combustion burners. The resulting molten glass is relatively foamy and may comprise greater than 25 vol. % gas bubbles. The molten glass is directed from the doghouse into an upstream end of the tank where it is refined to produce molten glass having on average less than 20 seeds per ounce.

  • Patent number: 10626047
    Abstract: A process for forming coating on an interior surface of a glass container. A glass preform is formed at blank molding station from a gob of molten glass. Thereafter, a glass container is formed at a blow molding station from the glass preform. A coating material comprising a suspension of nanoparticles in a liquid medium is introduced into an interior of the glass preform or the glass container while the glass is still hot from being formed. Heat from the glass is transferred to the liquid medium to vaporize the liquid medium and form a coating on an interior surface of the glass preform or the glass container. Thereafter, the glass container is annealed.

  • Patent number: 10367392
    Abstract: A rotary magnetic transmission structure that can achieve stable transmission is provided. Two magnetic members having radial magnetic fields are fixed on each shaft of two parallel shafts A and B; the radial magnetic fields of the two co-axial magnetic members both spread at an angle greater than 60 degrees and less than 90 degrees; using the first magnetic members of each shaft A and B as references, the direction of opening of the angle between the radial magnetic field of the second magnetic member and the radial magnetic field of the co-axial first magnetic member on the same shaft is opposite to that on the other shaft. This structure can obviously reduce the peak effect at the two poles of the magnetic fields of the magnetic members between the two shafts, so that the transmission is stable during non-contact rotary transmission.

  • Publication number: 20190168916
    Abstract: A glass container and a process for forming an inorganic silica coating on an exterior surface of the glass container to improve one or more surface characteristics of the glass container. A sol-gel solution including a polysilazane and an organic solvent is applied to the exterior surface of the glass container to form a sol-gel coating thereon. The glass container and the sol-gel coating are then exposed to a water vapor-containing environment and heated at a temperature of between 150 degrees Celsius and 600 degrees Celsius to transform the sol-gel coating into an inorganic silica coating. The as-formed silica coating has a hardness of greater than 8.5 GPa and is bonded to the exterior surface of the glass container through a plurality of siloxane bonds.

  • Patent number: 9272949
    Abstract: Certain example embodiments of this invention relate to the development of temperable UV blocking coatings having enhanced UV blocking efficiency and aesthetic appearance on stock sheets of glass substrates using large-scale wet coating manufacturing methods. A glass substrate is provided. A base coat is curtain coated on the glass substrate from a oxide precursor material including zinc, cerium, titanium, and silicon precursor materials. The base coat is cured. A top coat is roll coated, directly or indirectly, on the base coat, with the top coat being a sacrificial cross-linked organic polymer-based layer. The substrate is heat treated with the base coat and the top coat thereon. The base coat and the top coat are substantially uniform in thickness, and the heat treating removes substantially all of the top coat while causing substantially no cracking in the base coat.
