Abstract: A crib shield system includes one or more panels to be used with crib. The panels are formed, at least in part, of a mesh-type material (e.g., an integrated padded mesh material) that includes openings too small to permit an infant to insert a finger or toe therethrough. Further, the integrated padded mesh material may be used with one or more other apparatus (e.g., a blanket, a toy, etc.).

Abstract: A gas conveying duct-type heat exchanger is shown and described having two gases passing therethrough, preferably in counterflow relationship. An easily assembled, sectioned gas separator is provided to divide the duct into separate gas conduits. The separator sections are designed to fit with each other and to support heat pipes extending between adjacent conduits for transferring heat from one conduit to the next. The structure is adapted for ready on-site assembly and modification, thus providing facility in relating the constructed device to the heat load in a given installation and permitting shipment of a unit in disassembled condition.

Abstract: Structural support assembly for use in arctic and subarctic (permafrost) areas or in any areas where the upper ground layer is subject to a severe annual freeze-thaw cycle, including the cooperative combination of a support structure and a heat pipe element installed in generally frozen soil. The heat pipe is of a suitably complementary configuration and/or disposition with respect to the support structure to provide appropriate stabilization of the surrounding frozen soil. In one embodiment, the heat pipe element is disposed externally of the support structure and, in another embodiment, it is disposed internally of (and integrally combined with) such structure. The external embodiment further includes one version employing a linear (straight) heat pipe element and another version employing an angular (helical) element.
