  • Patent number: 10032601
    Abstract: A platen support structure adapted to thermally insulate a heated platen portion from a cold base plate while providing substantially leak-free gas transport therebetween and while allowing thermal expansion and contraction of the platen portion. Various examples provide of the support structure provide a tubular flexure having an internal gas conduit, a platen portion mounting tab connected to the flexure and having an internal gas input slot that is in fluid communication with the internal gas conduit of the flexure, the platen portion mounting tab being adapted for connection to a platen portion of a platen, and a base plate mounting tab connected to the flexure and having an internal gas output slot that is in fluid communication with the internal gas conduit of the flexure, the base plate mounting tab being adapted for connection to a base plate of the platen.
