Abstract
1324982 DTA device L OERTLING Ltd 27 July 1970 [14 May 1969] 24702/169 Heading H1K Apparatus for differential thermal analysis comprises an enclosure 3 in which are supported aluminium crucibles 4, 5 on separate nickel platforms 6, 7 in a hole or recess in each of which the bead of a thermocouple 8, 9, respectively, is welded, the crucibles containing a sample material and a reference material respectively. The bead is inserted into a conical hole (12) Fig. 2 (not shown) or a blind recess, Fig. 4 (not shown), prior to welding. In alternative embodiments the platforms are both of copper or silver, brass, aluminium, gold, stainless steel, platinum, rhodium-platinum, chromium-nickel, aluminium-nickel; "Chromel", "Alumel" or "Inconel" (Registered Trade Marks). The crucibles may be silver, platinum, platinumrhodium or "Inconel". Suitable metals for the thermocouple junctions are: chromium-nickel : aluminium-nickel; iron : constantan; copper : constanton; iridium - platinum : palladiumgold; iron-gold : chromium-nickel; gold-palladium-platinum : palladium-gold; and platinum: rhodium-platinum. The following abridgments are included in this series since the Specificataons were through an error, not allotted to this group. References to them will be found in the name index to this volume.
