Each of said nozzle assemblies (30) including a generally cylindrical body (36) having a centerline disposed in generally perpendicular relationship to said support (14), each of said cylindrical bodies (36) including a plurality of heads (38) extending generally radially therefrom at an axial extremity thereof remote from said support (14). Each of said nozzle assemblies (30) has four heads (38), whereby each head (38) of each cylindrical body (36) is at the same distance from adjacent heads (38) about the circumference of each of the of the cylindrical bodies (36), each head (38) of each cylindrical body (36) is of cylindrical shape and has its centerline
