Abstract

563,129. Magnetic switches. CIANCHI, A. L. Oct. 28, 1942. No. 15130. [Class 38 (v)] [Also in Group XXII] Two magnets 8, 9 must move before an armature 5 moves to close a circuit 2 3. The circuit 2, 3 may control a motor for operating a too for machining mag nesium, and car only be completec after two or more conditions are satis fied, for example (1) after a fan 14 drawing the magnesium-dust-laden air through water in a tank 12 is operating and (2) after the water in the tank has reached a certain height. The draught of air from the fan impinges on a vane 13 tilting a lever 9a and so removing out of effective influence the magnet 9 which embraces a tube 1 and holds an armature 5 in its upper position. The rising of the water level raises the magnet 8 which embraces the bottom 'of the tube 1 till it is able, provided the magnet 9 is removed, to pull down the armature and allow mercury to flow through holes in the float carrying the armature to complete a circuit between leads 2, 3. Specifications 485,259 and 493,355 are referred to.
