Abstract

894,341. Peltier cooling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 14, 1960 [July 20, 1959], No. 24853/59. Class 37. [Also in Groups XIII and XL (a)] A holder for a specimen in an electron microscope is located in aligned apertures in two adjacent blocks 1, 2 of semi-conductor material, e.g. bismuth telluride, of opposite conductivity type so as to be thermally insulated therefrom. The blocks 1, 2 are electrically connected, e.g. by means of metal cylinder 5, and a direct current is passed through them in such a direction as to reduce the temperature of the junction between the blocks. The specimen holder may be supported in a grid of thermally-insulating material located in cylinder 5 so that contaminating material in the electron microscope is deposited on the cooled surface of cylinder 5 rather than on the specimen. As shown, the edges of the blocks 1, 2 are nickelplated and soldered to cylinder 5 and to terminal rings 7, 8 which are spaced by insulation 9 and secured together by nylon screws 11. According to the Provisional Specification the cooling device may be used in apparatus other than electron microscopes.
