Abstract: A spider for a rotary molding process is provided. The spider includes an upper mold enclosure, a lower mold enclosure, and a clamping assembly. The lower mold enclosure is configured to selectively cooperate with the upper mold enclosure to facilitate retention of a mold housing therebetween. The clamping assembly comprises a collar, a plurality of brace members, and a clamping member. Each brace member is coupled with each of the collar and the upper mold enclosure. The clamping member is rotatably coupled with the lower mold enclosure and is rotatable about an axis in a clamping and unclamping direction. The axis extends through the collar. The collar is spaced from the upper mold enclosure along the axis. Rotation of the clamping member in the clamping direction facilitates translation of the collar towards the lower mold enclosure to facilitate urging of the upper mold enclosure and the lower mold enclosure together.

Abstract: Provided is an assembly for insulating substantially vertical runs of cooled surfaces that are continuously or periodically exposed to air or another gas that has a dewpoint temperature above that of the cooled surface, thereby resulting in condensation water vapor on or adjacent the cooled surface. One embodiment of the insulating assembly provides a wicking material layer adjacent the cooled surface that, in combination with transporting and evaporating structures, removes the condensate from the vicinity of the cooled surface and allows for its evaporation into the ambient gas surrounding the exterior surface of the insulating assembly. Another embodiment provides for exposing the condensate to an internal conditioned gas stream to provide for evaporation that does not necessarily utilize an exterior surface. Both embodiments remove condensate from the insulating structure and thereby tend to avoid any substantial condensate accumulation and maintain the insulating performance.

Abstract: An insulation product includes an elongated batt of fibrous insulation material, and a facing adhered to a major surface of the batt, wherein the facing is a coextruded polymer film of barrier and bonding layers, with the bonding layer having a softening point lower than the softening point of the barrier layer, with the bonding layer being one or more materials of the group consisting of ethylene N-butyl acrylate, ethylene methyl acrylate and ethylene ethyl acrylate, and wherein the facing has been heated to a temperature above the softening point of the bonding layer, but below the softening point of the barrier layer, whereby the facing is adhered to the batt by the attachment of the bonding layer to the fibers in the batt due to the softening of the bonding layer.
