Abstract

251,964. Schumacher'sche Fabrik Ges. May 8, 1925, [Convention date]. Porous artificial stones for filtering and other purposes are obtained by mixing a suitable mineral aggregate with a synthetic resin, moulding the mixture under pressure, and heating it to 100- 200‹ C. The porosity is controlled either by selection of a suitable size of the granular material or by the addition of volatile substances, e.g. heavy mineral oil, paraffin, earth wax, &c. Acid- and alkali-proof stones are obtainable by the use of suitable aggregates, e.g. fluorspar, coke, and quartz. Specification 156,675, [Class 22, Cements &c.], is referred to.
