摘要： An apparatus is disclosed, which serves to contact with a flowing gas two mutually opposite, substantially flat and substantially circular annular surfaces of an annular cylindrical workpiece having an inside diameter not in excess of a predetermined maximum inside diameter. The apparatus comprises an oven housing, which contains two mutually opposite plenum chambers, which are defined by respective side walls which are spaced apart in an axial direction and define between them an oven chamber adapted to accommodate said workpiece in a position in which each of said side walls faces one of said surfaces of said workpiece, each of said side walls being formed with orifice slot means, and a fan for supplying a gas to said plenum chambers. In order to ensure that the said surfaces of said workpiece will be uniformly supplied with said gas, said orifice slot means in each of said side walls consist of a circular annular slot, which is concentric to said circular annular slot in the other of said side walls, and the inside diameter of each of said circular annular slots exceeds the inside diameter of said annular workpiece, whereby said annular workpiece is adapted to be positioned in said oven chamber in a position in which said circular annular slots are concentric to said substantially circular surfaces of said workpiece.

摘要： A leveling apparatus for leveling a surface of refractory bed comprised of refractory pebbles. The leveling apparatus is comprised of a disk having a level bottom surface suitable for positioning upon the surface of the refractory bed. A plurality of spaced apart, downwardly extending tooth members project beneath the level, bottom surface of the disk, and into the refractory bed. Rotation of the disk causes the plurality of tooth members to displace the refractory pebbles in a rake-like manner to thereby level the surface of the refractory bed by causing the refractory pebbles to conform to the level bottom surface of the disk.

摘要： This invention relates to an apparatus and method for retaining the configuration of an aperture formed through a coil when the coil is supported on a saddle. The saddle has a pair of spaced apart upstanding legs. The apparatus includes a first and a second member, with the second member having a length sufficient to span the legs of the saddle. A pair of arms are pivotably attached to the first member and the arms are joined to the second member by a pair of links. The links enable the arms to move between a first position in which the arms are spaced inward and apart from the perimeter of the aperture when the second member is not in contact with the legs of the saddle and a second position in which the arms cooperate with the first member to support the weight of the coil when the second member is in contact with the legs of the saddle. The apparatus is particularly useful for supporting a coil during a heat treatment operation.
