Abstract

921,672. Magnetic switches. MATHER & PLATT Ltd. Jan. 17, 1962 [April 26, 1961], No.15106/61. Class 38 (5). [Also in Group XXIX] A liquid flow-detector and alarm device incorporates a flap a which turns about a spindle axis in a large-base water-pipe b shaped, at c, to conform with the flap so that when water flow occurs it is restricted until the flap has swung through an angle of, say, 30 degrees on either side of its central position, a small central drain-furrow being provided to prevent accumulation of a pool of water upstream of the flap. A magnet on the spindle (not shown) operates a microswitch in the circuit of an indicating instrument.
