Opinion

PARTRIDGE, District Judge.

The patents in suit here are for an improvement in the art of manufacturing illuminating and heating gas from crude oil and steam. The earliest gas, of course, was made from coal. A bed of bituminous coal was placed in a retort, and heated from below; the resultant gas passing off above. The first use of water seems to have been to force steam over the incandescent bed of coals; the water being decomposed and the result being hydrogen, as H2, and carbon monoxide. This was known as the “blue water gas,” from the color of its flame, and was of little or no use for illuminating purposes, although of great calorific (235 B. T. U.).

The next step was the invention of Prof. T. S. C. Lowe, the father of the plaintiff in this suit. See Guarantee Trust & Safe Deposit Co. v. New Haven Gaslight Co. (C. C.) 39 Fed. 268. His apparatus consisted of two vertical chambers, connected by a throat at the top. The second chamber was nearly filled with refractory brick, arranged in checkerboard formation. The first chamber was filled with coal, and, by means of an air blast, this coal was heated to incandescence. The gases thus produced passed through the throat, and thence into the second chamber, heating the checker brick to incandescence and then passing through a stack. When this has been accomplished, the outlet to the stack is closed. Steam is then admitted into the first chamber, and in passing through the incandescent coal, the following reaction ensues: C+2H20=2H2+C02.

Then the inert CO 2 is broken up as follows: C+C02=2C0. Oil is sprayed into the second chamber, coming in contact with the blue water gas from the first chamber, and down through the checker brick. In addition to the free hydrogen and the carbon monoxide, the luminous quality is largely imparted by the formation of various carbohydrates, such as ethan (C2H0), ethylene (C2H4), acetylene (C2H2), benzine (CeHo), methane (CHi), and their homologues. This method, however, was suitable only for the lighter oü; if the heavier were used, excessive heat was required, and the consequence was free carbon in such quantities as to clog the apparatus.

The next step, then, was the invention of the plaintiff. He devised a single chamber, containing checker brick. Oil, air, and steam were admitted at an intake at the bottom of the chamber, and fired. The heat and gases passed upward and were discharged at the top, until the brick were heated to incandescence. Then this lower intake and the outlet were closed, and steam and oil admitted at the top, passing down through the brick, and the resultant gases discharged at the bottom. Plaintiff then further modified this single chamber apparatus by a cylinder, having two series of checker brick, one above the other. Steam was admitted at the top of the upper series (thus acting as a superheater) and steam and oil at the top of the lower series of brick. From this the transition was easy to a two-chamber apparatus, both chambers being filled with the checker brick.

The plaintiff had patents covering these various improvements. On October 1, 1902, he granted to the predecessors of defendant licenses to use his machines in different territory. This method thus came into quite general use, and was quite generally successful. In large plants, however, there was a great objection to it, because it produced excessive quantities of lampblack. That resulted from the fact that the oil and the gases, having to pass the whole distance through the checker brick, were decomposed to the extent that the amount of free carbon was greater than could be taken up in [159]*159combination. Accordingly the plaintiff, in the latter part of 1903 or early in 1904, seems to have conceived the idea that he could obviate this difficulty by an intermediate outlet for the gas, so that it would be made in two directions. In December, 1904, one Jones, then in the employ of a predecessor of defendant, constructed two plants embodying this intermediate outlet, one at Sacramento and one at Fresno, both in California. Plaintiff applied for his patent on this improvement in August, 1905.

The plaintiff filed his hill in the usual form for infringement. The defendant answered, denying the allegations of the bill, except as to the issuance of the patents, and alleging:

(a) Lack of invention in view of the pri- or state of the art.

(b) Lack of utility and inherent inoperativeness.

(e) That Lowe was not the inventor of any substantial or material part of the thing patented.

(d) That if defendant’s practices constitute infringement, then plaintiff’s patents are invalid because defendant’s predecessors, including the California Gas & Electric Corporation, were doing the identical things now charged to infringe, prior to plaintiff’s alleged inventions, or either of them.

(e) That whatever Lowe sought to patent in his patents in suit was obtained surreptitiously from E. C. Jones, as gas engineer for the California Gas & Electric Corporation, who had been using reasonable diligence in adapting and perfecting the same. Section 4920, U. S. Rev. Stats. (Comp. St. § 9466).

(f) That defendant’s predecessor had in successful commercial and public use at Fresno, Sacramento, and "Woodland, as early as December, 1904 (some nine months earlier than Lowe’s dates of application), and at Vallejo, San Jose, Bedwood City, and Chico prior to said dates, apparatuses and processes involving the simultaneous making of gas in opposite directions and the use of a central outlet. Furthermore, defendant’s predecessor had a number of additional like plants in course of erection and concerning- which plaintiff must have had knowledge.

The ease was referred to a master, against the protest of the plaintiff, “to take the testimony and report the same to the court with his findings and conclusions thereon; the same to be subject to the full consideration of the court.” Evidence, amounting to nearly 4,000 pages, was taken, and the questions at issue were elaborately argued and briefed before the master. On the 15th of March, 1924, the master made his report, recommending decree for the defendant, upon the ground that plaintiff had not used reasonable diligence to perfect his invention, and that between the time of plaintiff’s conception of the intermediate outlet and his application for a patent the defendant’s predecessor (through Mr. Jones) had conceived the same thing and put it to practical use. The master, in view ,o£ this conclusion, deemed it unnecessary to consider the other defenses, such as lack of invention, no infringement, laches, and estoppel. Under the form of the reference, and the report, therefore, it has been necessary for the court to examine the whole matter as if it were submitted on depositions. Holt Manufacturing Co. v. Best Gas Traction Co. (D. C.) 245 Fed. 354. However, the main exceptions to the master’s report, and the burden of the oral argument and the briefs on exceptions, concern the real ground of the master’s decision as indicated above.

As bearing upon this, the basis of the master’s decision, there is a great conflict in the evidence. Plaintiff testifies, and the master found, that he conceived the idea of an intermediate outlet, with the gas “made” in two directions, late in 1903 or early in 1904. He says that he had a drawing made of his design; this drawing was not produced, the explanation being that it was burned in the great fire of April 18, 1906.
