1. In battery paste making equipment for mixing selected quantities of lead oxide, sulfuric acid and water to form a viscous mixture, control apparatus comprising:

  • temperature sensing means for determining the temperature of the mixture;

    viscosity sensing means for determining the viscosity of the mixture;

    valve means for admitting water to the mixture;

    coincidence means responsive to said temperature sensing means determining the temperature of the mixture to be a minimum temperature or above and to said viscosity sensing means determining the viscosity of the mixture to be at or above a maximum acceptable value of viscosity, for activating said valve means to admit water to the mixture until the viscosity thereof is reduced to a value below the maximum acceptable value, whereupon said viscosity sensing means disables said coincidence means, thereby de-activating said valve means.
