Abstract

974,201. Direction of revolution Indicators. P. A. GUINARD. Jan. 3, 1963 [July 12, 1962; Sept. 18, 1962], No. 405/63. Heading G1K. [Also in Division H2] In order to determine the direction of rotation of a carried electric motor used to drive a circulating pump in a central heating installation an annular magnet 46 is secured to the free end of the shaft so that a piece of ferromagnetic material placed in the recess in cover 22 will rotate with the motor rotor. In a further modification a bar magnet may be held in a slot formed in the end of the shaft, Fig. 3 (not shown). .
