APPEAL FROM THE CIRCUIT COURT OF TIIE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK.delivered the opinion of the court.
This is a suit in equity, brought in the Circuit Court of the United States for the Southern District of New York, by Charles Marchand against Frederick Emken, to recover for the infringement of letters patent No. 273,569, granted to the
The specification says: “This invention has reference to the manufacture of hydrogen peroxide, or oxygenated water, by addition of barium, or calcium binoxide to an acid (sulphuric, nitric, acetic, oxalic, hydrochloric, hydrofluoric, hydrofluosilic, and the like), the binoxide having been ■ mixed with water. Heretofore hydrogen peroxide has been made by adding, the barium or calcium binoxide, mixed with water, to the diluted acid, the binoxide being added from .time to time in small quantities, the vessel in which the operation is conducted being set in a refrigerating medium, and the liquid being agitated or stirred to facilitate the reaction. The stirring has'been performed by hand. The present invention is based on the fact or discovery that the reduction of the barium or calcium binoxide takes place under conditions ranch more favorable in point of rapidity and yield when the acid to be neutralized is given a movement of rotation, both vertically and horizontally, by a screw or other suitable means, which at the same time creates both constant and ever-changing eddies, th§-said movement of rotation being imparted continuously during the addition of the binoxide. The present invention ■consists, therefore, first, in imparting to the acid a movement of rotation, the time required for the chemical reaction being thereby lessened, while the reaction itself is more complete.”
The specification gives a description of the apparatus which it says is preferably to be employed and forms part of the invention, in substance, as follows: There is a receptacle for the acid, and a jacketing vessel, in which the receptacle rests, for containing the refrigerant or cooling medium. There is a rotating screw and a vertical power-shaft. The acid receptacle need not be of any particular size, but- a good capacity is from five hundred to one thousand gallons. It is preferably hemispherical, but may be cylindrical, frustoconical, or of other suitable form; and it is made of or lined with material adapted to resist the action of the acid. For use with hydrofluoric acid, a sheet-iron or, better, a copper vessel lined with lead may be used, or one of platinum, gold, or silver, or one
Only the first claim of the patent is involved in this suit. That claim reads as follows: “ 1. The method of making hydrogen peroxide by cooling the acid solution, imparting thereto a continuous movement of rotation, as well in vertical as in horizontal planes •— such, for example, as imparted by a revolving screw in a receptacle — and adding to said acid' solution the binoxide in small quantities, while maintaining the low temperature and the rotary or eddying movements, substantially as described.”
The answer, sets up, among other defences, that the alleged invention and patent do not contain any patentable subject matter. After a replication, proofs were taken, and, on a hearing, the court, held by Judge Coxe, entered a decree dismissing the bill with costs. From this decree the plaintiff has appealed. The opinion of the court is found in 23 Blatchford, 435, and 26 Fed. Rep. 629 .
It appears from the record that the first claim was three times rejected by the Patent Office, and was then, on appeal, allowed by the examiners-in-chief, who said in their decision: “ In the present case, the essence of the invention resides in imparting to the liquid, while making hydrogen peroxide as above, a peculiar motion — one which cannot be given by hand — a continuous movement of rotation, horizontally in opposite directions from the centre, or radially and vertically, or nearly so, according to the shape of the vessel, a vortical motion designated in German as wirbetbewegimg, the movement of a smoke ring, making what may be. termed a ring vortex.” They suggested an amendment to the specification, to make it clear that the invention was “ no more than in this particular art, all the other steps being .old,, imparting to the liquid undergoing chemical change this old motion, this motion produced, for example by the, egg-beater.’’
The opinion of the Circuit Court says: “ It is not pretended that the complainant discovered hydrogen peroxide, or the
A careful consideration of the evidence and of the arguments on the part of the appellant (no brief having been submitted on the part of the appellee) induces us to concur in the views of the Circuit Court.
Decree affirmed.
