Opinion

RAY, District Judge.

The Stauf patent, on which the complainant mainly relied on the argument (patent to Stauf, No. 666,711, of January 29, 1901, for method of desiccating blood, etc.), has been the subject of judicial examination and determination in Merrell-Soule Co. v. Powdered Milk Co. of America (D. C.) 215 Fed. 922, Hazel, District Judge, who arrived at the conclusion that the patent is valid and had been infringed by the defendant there. That case is now on appeal, and, as there was a supersedeas, no injunction is now in force. I would content myself with a reference to and an approval of that decision, but for the fact that the defendant now brings forward and urges the patent to Williams (British),' No. 22,655, applied for December 29, 1891, and issued October 29, 1892, as a complete anticipation, or as demonstrating that, in view of the prior art, the Stauf patent shows no invention and is void. Stauf, in his patent says:

“I * * * have invented certain new and useful improvements in methods of obtaining the solid constituents contained in liquid — such as blood, milk, and the like — in the form of dry powder.”

His process in substance is to eject the milk through very fine spray nozzles upwardly and laterally into a chamber (and the milk may be made quite warm before being sprayed, but must not be cooked in the slightest degree then or thereafter while undergoing the process) having and maintaining a predetermined temperature, “because if the proper temperature should be exceeded the dried powder might readily be decomposed,” .says the patent. Here conies in one of defendant’s criticisms. It urges that the patent fails to disclose the proper temperature, or'any temperature, to which the milk may or should be subjected in [579]*579bringing about the desired result without decomposing the solids of the milk or changing their chemical properties, and that, therefore, no disclosure is made which will enable a person reasonably skilled in the art to practice the invention. But I think it is expressed and understood that the heat must be such, and kept under such control, that the milk will not be scalded or cooked in the slightest degree, and that this temperature is easily determined or well known. .

At the bottom of this chamber into which the milk is ejected in this fine spray is a heating device, and its draught may be regulated by the admission of more or less air as desired. Hot air rises, but this rising of the heated air into which the milk is sprayed or thrown is made more acute or forcible by means of a pipe which supplies air under pressure to the spray nozzles carrying and ejecting the milk. It follows that the milk in the form of fine spray comes in contact and mixes with the rising heated air and is carried upwardly, and if the contact is long enough and the heat sufficient it will continue to rise and spread, if facilities for its spread be provided, and provision is made for the escape of the air at the top. At the top of this chamber or tower is another chamber of much greater lateral dimensions, and by suitable means this current of hot air is divided or diverted outwardly away from the mouth of the first chamber mentioned, and over a pit or pits which receives the dried milk or solids of the milk as it falls. The moisture passes out of this upper chamber into the outside v/orld through a sort of web, such as cheese cloth or the like, which retains any particles of the solids still floating and causes them to drop into the pits.

We have a new structure for carrying out this process, but I see nothing patentable in the structure itself as a mere structure. But the process itself was new and novel and useful. Cooked milk, or partly cooked milk — scalded milk — with the solids partly or wholly chemically changed, and with the water evaporated, was old. For the first time in this art Stauf separated the solids contained in fresh or new milk from the water and retained the solids in such form (a powder) and in such unchanged condition that on mixing this powdered milk (so called) with water he had again fresh, sweet milk, with the same properties as before it underwent the process. His means for carrying out the process were new in combination and in application. There was no new element, except, perhaps, in mere shapes and forms, but his combination of these elements was new. Stauf, therefore, invented a new and a useful process of great value to mankind, and he also provided means for carrying it out, and taught the world how to use it, unless Williams (British patent, No. 22,655, of 1891) was ahead.

It will be noted and remembered that Stauf’s process provides heat for heating the air, mainly all, if not all, supplied at the' bottom of the drying chamber, and it is forced, and partly, perhaps, drawn upward. In its upward course it overtakes and comes into contact and mingles with the fine sprays of milk, also having a tendency to rise, and which is ejected upwardly from the spray nozzles, and mixed with air introduced from nozzles at the same time at the same place upwardly. Thus we have two ascending currents, one of air and sprayed milk mixed, and another of hot air coming from below, but all commingling in the upper part of the chamber.' The arrangement and draught and process [580]*580■is such that the dried particles do not drop down on the heating apparatus, and the heat is so controlled and graduated that there is no scalding or burning of the milk when in vapor form or in the form of dried particles — powdered milk.

Now, turning to the Williams patent, we find that his is a process and an apparatus for “recovering salt from brine.” His claims read as follows:

“1. As means for the recovery of salt from brine, or alkali, alum, or other salts from liquids, the employment of towers or upright hollow shafts into the upper end of which the brine or liquid is forced and sprayed, either with or without the aid of an air blast, the said falling spray being met by a current or currents of hot air introduced at the foot of the tower or shaft, and of a temperature sufficiently high to evaporate the brine or liquid, and separate the contained salt or matter, substantially by the means and in the manner hereinbefore described and shown.
“2. The arrangement, construction, and combination of parts comprising my improved apparatus or means for recovering salts from brine solutions or liquids arranged and operating substantially as hereinbefore described and illustrated.”

The mode of operation is thus described:

“The mode of operating my invention is as follows: The air-heating portions of the apparatus having been brought to the required temperature, the exhauster in connection with the conduit e is set in motion, so as to draw hot air through the tower and thoroughly heat it. I then admit the brine current leading to the pipes f and at the same time turn on the cold air blast delivered by the blast pipes h. The cold air blows the brine in a fine spray from the delivery nozzles of the pipes f, and this spray showering down in the towers meets the ascending currents of highly heated air. The air‘is so hot that it completely evaporates the spray .before it can reach the bottom of the towers, and thus separates the contained salts or other recoverable matters in the brine, the said separated salts or matters falling to the bottom of the towers and being ejected by the revolving valves r r which direct it to the pit s, from which it is removed in any convenient manner.
