Abstract
25,732. JaffÚ, J. Nov. 22. Lithographic stones, artificial.-Relates to the manufacture of artificial stone, from Sorel and like cement, particularly that used for lithographic purposes, and comprises means for preventing excessive heating of the stone in the process of setting. For this purpose, the mould b, Fig. 1, which contains the moulding-material 6, is placed in a container a through which cold water is circulated. The mould is lined with parchment paper &c. before the moulding material, mixed in vacuo, is poured into it. Fig. 3 shows a mould closed by a cover f and wholly immersed in water. The mould is connected by a pipe g with the mixing and charging device, so that the whole operation of preparing the composition and charging the mould can take place in vacuo.
