A playhouse is provided that includes an outer structure and a roof supported by and positioned atop the outer structure. An identification of the IVR unit is captured within a supplemental interface device coupled to the user telephone device and to a computer data network. The method for producing the bodies includes the steps of providing pre-selected amounts of electric arc furnace dust, water, cement and aggregate. This reduces the number of file s that need to be considered when performing an index update. In another example, the radial adsorption bed surrounds a storage tank. Current in coils wound on the field poles provide selectable magnetic fields that interact with magnet flux in flux interaction regions to provide torque to the shaft.
