Abstract: A steam generator comprising a vessel having an inlet and an outlet, and in use a primary fluid flow enters the vessel through the inlet and exits the vessel through the outlet. A plurality of modules are connected in series and at least partially housed within the vessel, and each module comprises at least one tube. The modules are arranged such that at least one tube of one module is coaxial with at least one tube of an adjacent module so as to define a conduit through which a secondary fluid can flow from one module to an adjacent module.

Abstract: The present invention relates generally to a pancake mold article. More particularly, the invention encompasses a process for manufacturing a flexible, thin-walled, hollow pancake mold article. The present invention is also directed to novel non-metallic pancake mold articles. The present invention also encompasses a product made via the inventive process. The process for manufacturing the flexible, thin-walled, hollow pancake mold article comprises of at least one first vulcanization phase and at least one second vulcanization phase. Between the first and the second vulcanization phase the mold article can optionally be trimmed. The mold article can be wiped and cleaned after the second vulcanization phase. Preferably the mold article material is a food grade silicone, and optionally having at least one color.
