Abstract: An upper ring for an induction furnace. The upper ring is cast as one piece in a holder off of the furnace. The precast upper ring may be used as a replacement for the cast in place upper rings present on previously installed furnaces or may be used in the construction of new furnaces. The electromagnetic induction coil of the furnace may be modified to include cooling turns at its upper end when the holder with the one piece cast upper ring is installed on the furnace.

Abstract: A trowel comprises a flat, elongated rectangular blade having lateral edges and end edges. A pair of handles are pivotally mounted on the rectangular blade along the longitudinal centerline of the blade and adjacent each end of the blade. Each handle can pivot through at least 180.degree. from a first position extending substantially perpendicular to the material handling surface of the blade to a second generally opposite position extending substantially perpendicular to the material handling surface of the blade. This enables the laborer, holding the handles in the first position extending upward from the material handling surface of the trowel blade, to scoop up mud, stucco, plaster, mortar or other surfacing material from a pile with the trowel and then, by pivoting the handles from the first position to their opposite position, to apply the surfacing material directly to the wall being surfaced.
