PEDKBAL REPORTED.
The patented process provides for the treatment of beer when it is in the Kraueaen stage by holding it under automatically controllable pressure of carbonic acid gas by appropriate mechanical devices. When this stage ends the process is fully accomplished, and, in the understanding of the trade, the Krauesen stage terminates when the casksc6ntaining the liquid are Qunged. , Now, although it is admitted', that the respondents use the Guth patented bung, by means of which the complainant's process may be practiced, yet it iR satisfactorily shown by all the evidence that it is not used as long as the beer works out,of the bung-hole of the shavin,gs cask{l, but only when the are bunged, and,so when the patented process is, by its express)irp.itation, inapplicable. And this bung is not;8ven to produce any result contemplated, by the complainant's process, but only off the beer from the llhavings casks, and ,as a means of relieving them frqm I!-n excessive pressure of carbo,nio acid gas. Weare, therefore, of opinion that the respondent is, not ShOWIl to have used the complainant's proclils8, and so to have infringed iis patent, a:Q,(i that the bill must be dismissed, with costa.

solution of camphor in any thing which would dissolve it, would be a solvent of xyloidine. Of the eight ,mixtures mentioned as solvents of xyloidine, camphor is in only' five. The discovery is that the· mixtures named are the solvents. If the wood alcohol used by the defendant is of itself a solvent of xyloidine, and is the same thing known as a solvent of it, under the name of wood naphtha, at the date of Parke's patent No. 1,313, the defendant ,may use it in con· junction with' camphor, because such use is made known in No. 1,313. If such wood alcohol is a new article, discovered since the plaintiff's invention, it may be used by the defendant, because the patent covers only the use of alcohol or spirits of wine with camphor; . and such new article is not alcohol or spirits of wine, and is not within the claim. The claim· does not cover anything which may be discovered subsequently to effect, in conjunction with camphor, as good a result in dissolving xyloidine as the use of alcohol or spirits of wine in conjunction with camphor. And even though the defend. ant's wood alcohol be methyl alcohol, and an article known by that name before the plaintiff's invention, it cannot be held that the plaintiff discovered the usefulness of it in conjunction with camphor to dissolve xyloidine, because his patent is expressly limited to that alcohol which is spirits of wine, and that is not methyl alcohol. The motion is denied, with costs.
