摘要： This invention relates to heat treating furnaces which employ electric resistance heating elements and, in particular, to improved processes for repairing such furnaces and heating elements particularly useful in such repair. A typical vacuum furnace employing this invention provides a hot zone that is made for heavy duty heat treating applications. The furnace has a series of banks of axial-spaced electrical resistance heating elements suspended from an inner wall of its hot zone chamber by a series of support rods. Repeated furnace use can result in heating element fractures, which necessitate replacement of the heating elements. The replacement in accordance with this invention is with an element having a thicker and narrower cross section than previously existed in the furnace. The specially designed width-to-thickness aspect ratio heating elements according to this invention enables the elements to have a longer life between replacements.

摘要： A device for separating interconnected transport boats that are movable in a first plane in an intended direction of motion includes a substantially oval, non-circular separation disk aligned parallel to the first plane and connected to a rotary drive and a lifting device via a drive shaft. The separation disk is movable by means of the lifting device in the direction of the transport boats to be separated in order to engage with a corresponding total recess in the transport boats to be separated. In addition, the separation disk is rotatably movable in, and/or parallel to, the first plane by means of the rotary drive in order to separate the transport boats to be separated from each other by rotating the separation disk.
