Abstract

502,557. Magnetic tests. UNGER, F., and HILPERT, R. S. June 16, 1937, No. 2393/38. Void. Convention date, June 17, 1936. Divided out of 497,095 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 18, 1937. [Class 37] Magnetic figures to indicate the disposition of magnetic fields are produced by a whirling of ferromagnetic powder in a gas, for example, air, contained in a vessel. The whirling powder may be caused to flow through the vessel.
