Show FLOTATION DECISION IS FAR-REACHING The decision of the court of appeals in San Francisco in the case of Minerals Separation vs. Butte & Superior, reversing revers-ing Judge Bourquin's decision at Butte, is a serious blow to the pretensions of the plaintiff. We must defer extended comment com-ment upon this until the full text is received. re-ceived. This was the case in which Butte & Superior, bowing to the decision of the supreme court as to the limitation of the patents to the use of less than 1 per cent of oil, altered its process so as to use more than 1 per cent; whereupon Minerals Min-erals Separation claimed that to be merely mere-ly an evasion, alleging that the excess of oil played no useful part, and was upheld in that contention by Judge Bourquin. According to the telegraphed reports, the San Francisco court has construed the decision of the supreme court so as to limit the Minerals Separation patents to not more than 0.5 per cent of oil. If this be reported correctly, it will make the flotation process more free in the matter of oil admixture, besides which the matter of the Callow process remains open, at least so far.
