Abstract: Nickel-iron-cobalt based alloys are disclosed having sufficient castability for centrifugal casting essentially free from casting defects, cracking, and microstructure variability, and coefficients of thermal expansion up to about 9×10?6/° C. for about 100-400° C. and increasing from about 400-500° C. to up to about 10×10?6/° C., or up to about 6×10?6/° C. between about 100-300° C. and increasing from about 300-500° C. to up to about 10×10?6/° C. Articles are disclosed including unitary cast structures free of internal welds, brazing, and bolting, essentially annular conformations, diameters of at least about 500 mm, cross-sectional wall areas of at least about 2,000 mm2, and compositions including nickel-iron-cobalt based alloys. Methods for forming the articles are disclosed including rotating centrifugal molds with the compositions in molten states, forming the articles in near net shape.

Abstract: 1. An apparatus for treating a measuring probe has a treatment chamber (104) with a chamber inlet (106) and a chamber outlet (108). A conveyor device (110) selectively conveys one of a plurality of treatment media (G, W, R, E, Z) from its respective supply port (118a, 118b, 118c, 118d, 118e) to the chamber inlet (106) and into the treatment chamber (104). The conveyor device (110) has a collector conduit (120) and a conveyor pump (122), the latter arranged between the collector conduit (120) and the chamber inlet (106). Each of the supply ports (118a, 118b, 118c, 118d, 118e) has its own shutter device (124a, 124b, 124c, 124d, 124e) arranged directly at the collector conduit (120).
