Abstract: A multilayer flooring panel for flooring and the like has a cementitious top surface, a lower density intermediate layer preferably incorporating expanded polymeric beads mixed with cement, and a lower layer reinforced by tension-bearing fibers embedded therein. The interface between the top and middle layers may be upwardly domed to reduce the tendency for cracks to form in the bottom surface of the top layer. Channels formed along the edges of such tiles allow insertion of heat transfer tubing to provide a hydronic floor surface. A flooring panel may have cementitious top and bottom surfaces with an intermediate lower density layer there between. Such intermediate layer may be divided into two portions by a water impervious layer that serves as a binder and vapor barrier.

The interface between the top and middle insulative layers may be upwardly domed to reduce the tendency for cracks to form in the bottom surface of the top layer. Channels formed along the edges of such tiles allow insertion of heat transfer tubing to provide a hydronic floor surface. A composite tile may have cementitious top and bottom surfaces with an intermediate lower density layer there between. Such intermediate layer may be divided into two portions by a water impervious layer that serves as a binder and vapor barrier.

Abstract: Method and apparatus for erecting carton blanks having preformed fold lines in which flat carton blanks are pressed into a pair of hollow forming shafts by a plunger assembly of complementary configuration to form hingedly connected lid and tray portions.The plunger assembly comprises a pair of movable plunger members which undergo synchronized translational and rotational movement and in cooperation with a swingable plate to erect hingedly connected sidewalls of the tray and lid portions. When the side panels of the lid and tray portions of the carton are erected, they are held by the plunger assembly against stationary bottom portions of the shafts. Finger assemblies undergo rotational and reciprocating motion to fold glue bearing edge flaps of the lid and tray portion into their assembled position to maintain associated side panels in their erected position to enable the glued portions to "set". A novel carton blank which is provided with "biasing tabs" is also described.
