An improved extruded polypropylene sheet that contains a high level of beta crystallinity and a process for making such sheets are disclosed herein. The polypropylene sheet contains at least one layer of a resinous polymer of propylene and an effective amount of beta spherulites. The beta spherulites in the sheet are produced by the incorporation of a beta nucleating agent in the polymer. The presence of the beta spherulites in the sheet facilitates the process of post-stretching the perforated sheet to produce a uniaxially or biaxially oriented mesh structure, and also broadens the temperature range over which this stretching can be performed. The final mesh has a lower density than a polypropylene mesh without beta spherulites. The perforated beta nucleated sheet also exhibits different stretching characteristics during the orientation steps such that more resinous polymer is drawn out of the node junction region between the machine direction and transverse direction oriented strands and a greater percentage of the web area has a solid polymer structure. This altered stretching behavior results in an oriented web that has higher strength and torsional rigidity characteristics. Thus lighter weight mesh structures which meet all of the physical property requirements for end-use applications, such as reinforcing grids to stabilize concrete and soil in civil engineering and landfill applications, are produced. The lighter weight extruded beta nucleated sheet can also be stretched at higher line speeds, thereby reducing the manufacturing costs.

An improved pocketed bed sheet is provided that avoids inadvertent placement of objects in a pocket, better controls placement and removal of objects from within its pocket, and deters babies and toddlers from accessing such pocket, all without the need for engagement or disengagement of a fastening member. The improved pocketed bed sheet includes a fabric body configured to substantially cover a mattress and a pocket provided on the fabric body. The pocket includes a wall configured to hold objects in the pocket and a diagonal fabric edge that defines a diagonal opening for predetermined angular ingress and egress into the pocket for controlling the placement and removal of objects within the pocket. The diagonal fabric edge is disposed at an angle relative to an edge of the fabric body.

Improved extruded polypropylene sheets containing a high level of beta crystallinity and A process for making such sheets are disclosed herein. The polypropylene sheets comprise a resinous polymer of propylene and an effective amount of beta spherulites. Uniaxially or biaxially oriented mesh structures produced from the disclosed sheets exhibit lower density, higher strength, and higher torsional rigidity than polypropylene meshes without beta spherulites. Thus, lighter weight mesh structures which meet all of the physical property requirements for end-use applications, such as reinforcing grids to stabilize concrete and soil in civil engineering and landfill applications, are produced. The lighter weight extruded beta-nucleated sheet can also be stretched at higher line speeds, thereby reducing manufacturing costs.

A heat exchange chamber includes an inlet, an outlet and a plurality of walls defining a chamber interior. The inlet receives a heat exchange medium flowing in a first flow direction in an initial line of flow. Disposed within the chamber interior is a medium directing member, having an inclined surface, which diverts the medium from the initial flow direction so that it disperses within the chamber interior. The medium exits the chamber, via the outlet, in the initial line of flow. The chambers are interconnected by tubes to form assemblies. Plural sets of chamber and tube assemblies are arranged between manifolds to provide a heat exchanger.
