Claims44
An apparatus for use in processing molten glass, the apparatus comprising
- a shank having at least one tube which is composed, at least in part, of an oxide dispersion-strengthened PGM material;
- an actuating device arranged on the shank;
- and
- a tubular device, wherein
- said actuating device includes a hollow portion,
- said shank includes at least one thickened portion at a location where the actuating device is connected to the shank,
- said tubular device extends into the hollow portion of the actuating device,
- said actuating device is adapted for contacting molten glass,
- the shank includes a sleeve for strengthening the shank against evaporation that results from being placed in contact with molten glass, and
- the shank includes an orifice, and there is arranged a clearance between the shank and the sleeve, at a location adjacent to a weld seam of a blade element, for venting air located in a region of the weld seam into an interior of the shank.
