Abstract

172,272. Straatman, J. F. Dec 3, 1920, [Convention date]. No Patent granted (Sealing fee not paid). Purifying liquids.-In a process for decolorizing liquids by the use of an adsorbent and a reducing agent in conjunction, the adsorbent is allowed to remain in contact with the material while the reducing agent is applied. Examples are given of the treatment of sugar solution with bone charcoal and sodium hydrosulphite. Sulphur dioxide may also be employed. The Specification as open to inspection under Sect. 91 (3) (a) states that the reducing agent may be applied first, or some adsorbent may be applied first and filtered off and the reducing agent may be applied, followed by more adsorbent. This subject-matter does not appear in the Specification as accepted.
