Abstract

392,755. Pyrometers. UGINE-INFRA, 21, Rue du Drac, Grenoble, Isere, France. June 23, 1932, No. 17804. Convention date, Sept. 9, 1931. Drawings to Specification. [Class 97 (iii).] In a pyrometer which utilizes the property of magnetic bodies of variation of permeability over certain temperature ranges, the magnetic body comprises removable elements which may be replaced by similar elements of different magnetic material so as to vary the temperature range over which indication occurs.
