  • Patent number: 10717104
    Abstract: A coating system and related method for coating a part. The coating system having a process tank filled with a fluid coating material to a fluid coating level and an inert gas blanket formed above the fluid coating level. The coating system also having a process tank conveyor to support a part to be coated. The process tank conveyor having a submerge section which transfers the part through the inert gas blanket and below the fluid coating level, a coating residence section which maintains the part submerged below the fluid coating level for a coating period, a coating removal section which raises the part above the fluid coating level but below the inert gas blanket level, and an inert gas blanket residence section which maintains the part within the inert gas blanket level but above the fluid coating level for a drying period.

  • Patent number: 10556749
    Abstract: A conveyor system is disclosed and includes a plurality of conveyor sections, a lift assembly, and a telescoping joint. The conveyor sections define a conveying path extending from an upstream conveyor section to a downstream conveyor section with a translatable section disposed therebetween. Further, the translatable section includes a declined section, an inclined section, and an intermediate section. The lift assembly is operationally connected to the translatable section and includes a fully lifted position, a fully lowered position, and a plurality of intermediate positions therebetween. The telescoping joint is operationally connected to and positioned between two of the conveyor sections of the translatable section and is configured to contract in a linear direction as the lift assembly is actuated toward the fully raised position and is configured to expand in the linear direction as the lift assembly is actuated towards the fully lowered position.
