Abstract

30,297. Compagnie pour la Fabrication des Compteurs et MatÚriel d'Usines Ó Gaz. May 2, [Convention date]. Mercury motor meters; temperature errors, compensating for. - Magnetic shunts S made of steel containing a considerable proportion of nickel, the permeability of which steel diminishes with a rise of temperature, a r e placed between the poles of the permanent field magnet of a mercury motor meter, to compensate for the increase in resistance of the rotor C, and consequent diminution of braking effect, caused by a rise of temperature. The rotor is in the form of an inverted bell, the edges of which are amalgamated, and the rest of the surface varnished. The mercury reservoir E is made of moulded insulating material. One pole of the magnet extends into the bell so that the flux crosses the rotor only once. The jewels for the rotor spindle are mounted on springs, and a plug G is provided for closing the mercury reservoir during transit.
