Abstract: A broad uniform source (e.g. LED or laser) (1) is coupled to two fibres (2,2') having similarly temp.-dependent properties.  These fibres feed respective sensors (8,8') terminated in mirrors (9,9') from which the reflections are diverted (17,17') to a receiver (14) with a sliding slit (18) for exposing the photodetector selectively to the sensor under test (8) or the reference sensor (8'). As the latter is not connected mechanically to the sensor under test, although close to it, the temp. response is compensated by virtue of the similarity of properties of the two fibres.  Likewise variations of transmitter power or receiver sensitivity with time can be compensated.

Abstract: A continuous casting furnace (10) of modular design. In one embodiment the furnace is made of a crucible section (16), a feed section (18) and a die section (12). Each of these various sections are separable from the other parts, and each of these parts is in turn made up of various individual components. Thus, the crucible section includes a refractory liner (24) made of a non-carbon containing material which may be disposed within a monolithic graphite crucible (22). The graphite crucible is provided with a cylindrical aperture at its bottom which receives a feed tube (30), there being a soft seal (32) between the bottom of the liner (24) and the top of the feed tube (30). The feed section and the die section are generally formed in the same manner in that there is a non-carbon containing refractory tubular member (48, 64) disposed within a graphite member (50, 62). Between the feed section (18) and the die section (12) is a soft seal (66). In another embodiment the crucible section and feed section are integrated, there being a monolithic graphite crucible and feed housing (100), which housing supports a crucible liner (24) and a feed tube system (102) formed of sintered alumina rammed cement. The soft seals (34, 66) are formed of a soft felt or the like fabricated from aluminum oxide, zirconium oxide or other suitable fibers which may be impregnated with a boron nitride slurry. The various parts are held together using conventional fastening means.
