Abstract: A method and apparatus for removing TDI from a gas in which the gas containing the TDI is forced through a scrubber tank. A first water spray is in fluid communication with the gas flowing through an inlet pipe and initially reacts the TDI in the gas with water. The gas is directed against a water surface at the bottom of the tank and thereafter, flows up an interior side wall of the tank. Deflectors mounted on the side wall disrupt the laminar flow of the gas and redirect it in a turbulent manner through a second water spray prior to the gas exiting the scrubber tank.

Abstract: A method of forming foam buns including the steps of pouring foam in a liquid state onto a fall plate, preventing the forming of skin on upper and lower surfaces of the foam during a creaming state thereof as the foam advances along the fall plate and onto and along a conveyor, removing the formed bun from the conveyor, and causing a cooling gas to be forced through upper and lower surfaces of the bun and through the bun to effectuate rapid cooling of the bun. To prevent a skin from forming on the lower surface the fall plate is insulated to prevent heat transfer from the lower surface to the fall plate and the consequent forming of a skin on the lower surface of the bun which would normally result.

Abstract: An improved paperboard shipping container having a relatively gas impervious lining or layer located exteriorly to an insulated cold or hot storage compartment comprised of sized panels of open-celled, non-rigid foamatious insulating material enclosing substantially all of the cold or hot storage compartment.
