PORCELAIN INSULATORS. The R. Thomas & Sons Company, East Liverpool, Ohio. -- An attractive catalogue describing and illustrating high-grade porcelain insulators for high-tensions power transmission and electric light, street railway, third rail, underground trolley, and telephone and telegraph lines. The insulators are made by the "glaze-filling" process which, it is claimed, results in their being thoroughly vitrified. The catalogue also contains a few suggestions as to the line-working voltage of the various types of insulators it describes.
