'.'ear Johnson: I an in receipt of your Letter of July 17th relative to future negotiations with the A. ifilhelm Oonpsny and ''r. 1. i. 'ira.ul relative to the production of basic lend acetate solution and lead chromate in the Sperry cell. , In reply tot he second to the last paragraph of your letter, I think you are under a nisapprehonsioa where you say " pre 3unably l`r.

Personally, I do not think wa should try to induce pea.ple to use tho Sperry process for any oarpose. If they want to use it, I think we should let them do so if they will agree to nay us a reaaonable royalty either aa a lump sun or otherwise, but I don't think we should iaoortuna sn7 concern to use either process nor to take the initiative In any such negoti ations. In my opinion, me will never get the returns in royalties to commensurate with the amount of trouble we will haro to go to. An a c o n d a Le a d Pr o d u c t s Co mp a n y Ka s t Ch ic a g o ,In d ia n a July 17th, 1936 Mr. Frederick Lai3t, Vice-President, Anaconda Lead Products Conpaay, Room 1720 - 25 Broadway, New York, N. Y. Dear Mr. Lai at:- I am enclosing copy of a letter of June 29th from Mr. H. E. Graul of the A. Wilhelm Company, which is in reply to ny letters of June 15th and 17th, copies of which I forwarded to your office at the time they ware mailed to Mr. Graul. We are very much surprised at the thoughts expressed by Mr. Graul in the first paragraph of his letter, in Milch he emphasizes the interest of their company in the Sperry cell for the production of a basic lead acetate solution. The ohly guess I can make as to reasons for insisting that we further consider the possibility of the Sperry cell for the production of a basic lead acetate solution is that they are accustomed to reasoning only along chemical precipitation lines and not on electrochemical methods of precipitation. With this line of reasoning, they may feel that unless we can supply them with a basic lead acetate solution, which by precipitation will produce a satisfactory grads and color of lead chromate, that the Sperry cell would not be satisfactory for lead ehrcmate production. Therefore, in reply to the questions asked in the first paragraph of this letter, we might well point out to them that our Research Department contend that the Sperry cell would be a more expensive method of producing a lead acetate from pig lead and acetic acid than it would be by chemical reaction between metallic lead and acetic acid. This statement is undoubtedly correct, except for the possibility that in our recent developments at the White Lead Plant there is indicated the possibility that an unrefined lead anode might be used as a source of lead, and there by result in a cheaper eource of lead acetate. However, we would he very reluctant at this time to reveel to the Wilhelm Company the real possibilities of the Sperry cell for using impure metals. The.second paragraph of Mr. Graul*s letter is very pleasing to us, since he - defi nit ely states that they will be interested in the possibility of the Sperry cell producing chrome yellows direct* This acknowledgment of their intereat, after being advised that we have filed application far patent and have actually produced chrome yellows in the Sperry cell, should dispose of the question of their having made application for a patent on the electrolytic production of chromates. N11461.01 An a c o n d a Le a d Pr o d u c t s Co mp a n y Ka s t (Iu ic a o o .In d ia n a Sheet 2 - Mr. Frederick Laist July i 7th, 1936 In going over this particular phase of Mr. Graul'a letter with Mr. Stockdala, we feel that we are not quite prepared to completely reveal and discuss with the Wilhelm Company the information wo have obtained on the cell control for the production of lead chromates. Our reason for this attitude is the fact that we find we can quite readily produce the yellow and orange lead chromates, but we are still working out the cell control for the production of the so-called deep orange lead chromates. It is quite likely that the real interest of the Wilhelm Company in electrolytic lead chromate production is in its possibility of satisfactorily making the deep orange lead chromates rather than the yellow and orange chrcmates, .which latter two are easier to produce by chemical precipitation methods. In view of this situation, naturally we cannot definitely predict just when we will develop the cell control necessary to`completely reveal the process to Uie Wilhelm Company, and therefore some plan should be devised to allow us sufficient additional time to perfect the process. In the third paragraph of his letter, mention is made of the interest of Mr. Craul and Mr. Hirsch in a visit to our laboratories, with presumably the thought in mind that they could ascertain, by a visit, how much work we had done in the Sperry cell on the production of lead chromates. Obviously, with the information I have given in the preceding paragraph on the status of our cell experiments for the production of lead chromates, it would not be advisable for Mr. Hirsch and Mr. Graul to visit us until we are prepared to show them the cell in operation, producing all commercial grades of lead chromate. We are of the opinion that when we have perfected the cell control for the production of lead chromates and are able to show them the experimental cell producing the commercial grades of lend chromate that they will lose interest in the lead acetate question. In the thoughts expressed in thls latter, I have attempted to analyze the situation covering each specific question by Mr. Graul, and our position with reference to each of these questions acked by -him. It is apparent to U3 that we.noed additional time before proceeding very much further with the negotiations, which ultimately, we understand, will lead to a non-exclu3ive license to the Wilhelm Company. A method of gaining additional time would be to have our Research Department prepare synthetic basic lead acetate solutions Ka s t Ciu o a o o ,In d ia n a Sheet $3 - Mr. Frederick Laist July 17th, 1936 of an approximate composition indicated in pant correspondence with Mr. Graul, which we would forward to him with the understanding that these synthetic baaio load acetate solutions were prepared merely with the thought of establishing definitely the basicity of the lead acetate which was necessary for the satisfactory production of basic 'load chromates by the process as now used at Reading. This plan has the advantage that we could frankly advise them that we were not particularly impressed by the commercial possibilities of the Sperry cell for the production of a basic lead acetate, and yet wa would co-operate with them to the extent of possibly clearing up some other questions that they apparently have in mind, and which we are at a leas to understand. In addition to the reasons I have given above for additional time to complete our investigation, it is my under standing that before any definite steps are taken toward negotiations for a non-exclusive license to the Wilhelm Company, someone in the Anaconda organisation, presumably Mr. Glass, was to approach the Sherwin-Williams Company to determine whether they were interested in a non-exclusive license for the production of lead chromates by the Sperry cell. As far as wo know, nothing ha3 been dona toward approaching tie Sherwin-Williams. Company on their possible interest, and again it may be that we are not quite ready to fuily divulge to Sherwin-Williams the extent of our development work at this time. I would very grsatly appreciate your comments and suggestions on this dlacn33ion of the enclosed letter from Mr. Graul, and particularly the forte of reply to his letter which might bs satisfactory to Mr. Dwyer and yourself. Very truly yours, GEj/s ce- Mr.R.S.Dwyer Mr .0. Glass Mr.?.0.Case Manager. THE A. WILHELM COMPANY READING, PENNSYLVANIA June 29, 1936 Mr. G. E.

Laist: In view of the recent inquiry of Mr. Case concerning patents of The New Jersey Zinc Company, relating to processes of the type of the Wetherlll process, which are about to empire, I consulted the available records and noted a number of patents which probably will be of interest to him. In addition to patent No. 1,322,142 which expires next November and about which Mr. Case inquired specifically, I noted the following patents which relate to the same subject matter and which also expire next November: Patent Number Date of Issue 1.322.088 1.322.089 1.322.090 1.322.091 -1,322,142 1,322,143 November 18, 1919 tt ft ff ff Date of Expiration November 18, ff ff n ff rt 1936 I was unable to find any later patent granted on an application relat ing back to the applications on which the aforementioned patents were granted and providing additional protection for the inventions N11461.05 Mr. Frederick Laist -2 covered by those patents. It appears, therefore, that upon the expiration of these patents, the processes described therein will be open to use by the public ar.d may be used without infringing any later issued patent. Similar processes are described in the following patents which already have expired: Patent Number Date of Issue Date of Expiration 1.112.853 1.112.854 1,257,136 October 6, 1914 Tt February 19, 1918 October 6, 1931 rt February 19, 1935 The following are unexpired patents describing processes carried out in traveling grate furnaces; Date of Patent Number Issue Date of Expiration 1,450,704 1,670,169 - Acril 3, 1923 May 15, 1928 April 3, 1940 May 15, 1945 The above-listed patents are the more important of those owned by The New Jersey Zinc Company and covering operations carried out in traveling grate furnaces. I have not taken the time to coirsider all of the later patents of The New Jersey Zinc Company which might have sane bearing on such operations, but I shall be glad to do so and obtain copies of all other pertinent patents for Mr. Case if he is interested.

Frederick Laist, Vice-President, Anaconda Lead Fro diets Company, Room 1720 - 25 Broadway, Hew York, N. Y. June 22nd, 1936 Dear Mr. Laist About a year ago the local management of the Crasselli Chemical Company requested permission to have two of their men from the Cleveland plant visit our operations, particularly the electrolytic white lead operations. We were advised at-'that time that these engineers were making a study of electrochemical process in general, and since the Sperry process was unique in this line of work they would like to acquaint themselves with the theory and the operation of the cell. The local plant has been very courteous in exchanging information with us in the past, and we therefore advised them that this would be entirely sat isfactory to us. On Friday of laBt week Mr. C. W. Bower, one of the officials of the local plant of Crasselli, telephoned me to inquire whether one of their research men could visit our White Lead Plant. The Individual in question is Mr. O'Brien, who is the son of a former general superintendent of the East Chicago plant. Mr. Bower advised that Mr. O'Brien was one of the men who visited the plant about a year ago, and was making a study of electrolytic processes in general. He also advised that we should only give Mr. O'Brien information which was within the limits allowed by our company policy. Mr. O'Brien called at the office Friday afternoon end advised Mr. Knox, to whom he had been referred, that the Crasselli Company was producing lead arsenate at East Chicago at the rate of about 20 to 25 tons per day for approximately 8 months per year. They have apparently been studying the possibility of making lead arsenate by the electrolytic process as possibly offering some advantages in a lower cost, and also possibly a little more flexibility in making the different grades of lead arsenate as regards physical characteristics. Apparently their investigation had proceeded to the point idle re they were more Interested in cost at operation and maintenance, having- presumably-decided that the fundamental characteristics of the Speny cell were satisfactory for the production of lead arsenate. They were also particularly interested in the cell voltage, and had assumed four volts per cell. 1873 N11461 Mr. Knox advised them that their voltage figure was very likely high for the production of lead arsenate, but beyond this, advised Mr. O'Brien that he was not in a position to estimate cost or give him cost figures without approval from our New York office. Mr. Knox suggested to Mr. O'Brien that if their company was considering the electrolytic production of lead araenate by the Sperry cell that it might be advisable to make some arrangements between the Grasselli Chemical Company and our company, looking toward an exchange of information which might help them decide the posaibilitiea of the 3peri7 cell. We were surprised to know that the Grasselli Chemical Company had been seriously studying the Sperry cell far this purpose, and apparently Mr. O'Brien had a great deal of c031 data on the possibilities of the Sperry cell for this purpose. This fact, coupled with the Interest of the Wilhelm Company and the admit ted interest of the Eagle Pioher Lead Company on the date on which the basic Sperry patents expire, and other incidents that have come to our attention in the past several years, indicates that the chemical end pigment industry are interested in the future possibilities of the Sperry cell. Mr. Knox gathered the impression that Mr. O'Brien was rather of the opinion that their company could proceed with the installation of a Sperry process for lead arsenate without any Interference on the part of the Anaconda Lead Products Company, or at least that the Anaconda Lead Praiucts Company was not interested in this type of process because of the danger of arsine to our workmen. Mr. Case and I talked over the Grasselli Company's interest in lead arsenate, and we both felt that we should advise you and Ur. Dwyer of this new interest, with the thought that ycu could advise us on how to proceed with them to avoid patent complications sad also, if we are interested in helping them develop a lead araenate process, how the necessary steps to keep in touch with them might be arranged. We wculd greatly appreciate your comments and suggestions.

Y. Bear Mr. Laist:- I wish to thank you for your letter of June Sth with reference to the interest of the Reading plant of the (Hidden Company concerning lead chromate. I cm glad to have your opinion on the letter as I prepared it. In accordance with your suggestion, I have drafted the enclosed letter to Mr. Graul which is, with the exception of two minor revisions, the letter which you suggest be written to Mr. Craul. I believe these two changes will not in any way change the thought in the letter nor its intent. I have also gone over the question and your letter with Mr. Case, and he is agreeable to your suggestions. I rather imagine Mr. Graul, upon receiving the enclosed letter, will probably have to give the matter same thought, then he probably will take it up with the executive officers of the Glldden Company to determine whether they are interested in the electrolytic produstlon of lead chranates. Frcaa the thoughts expressed by Mr. Graul on lead chromate during my visit at Reading, I am somewhat inclined to believe that ha will feel that since we will obtain a patent cm the production of electrolytic lead chromate that we plan to produce lead chromate, and therefore their interest- in using the Sperry cell will cease. I presume there would be no objection to having such a situation develop. However, in our correspondence on this question, there are indications that we migit be interested in giving SherwinVillimas and the Glldden Company a non-exclusive license to produce electrolytic chromate. Therefore, I am somewhat uncertain whether it is your thought that the matter should be closed at this time with tto Glldden Company, or whether we should attempt to keep the question open long enough to have the decision of the SherwinVillisms Company as to their interest. g et /s enel. ce-Mr.R.S.Dwyer Mr.C.Glass Mr.7.0.

I E..i in accord with the contents and suggestions in these letters with the possible exception of the licensing of the Glidden Company to use our patents for the production of lead chromate. Personally, I have no objection to the Glidden Company having these but from the standpoint of the Anaconda organization I seriously question the advisability of licensing, or suggesting a license, to Glidden until after the Sherwin tuns has had an opportunity to get the same privilege. The Sherwin "'lllieias Company compete with Glidden in the sale of dry colors including lead chromate and we have every reason to believe that the-Glidden Company would be in a very advantageous position on lead chromate if they made it by. our patents. This would undoubtedly cause more trouble far us from Sherwin '."illie.ms than for us to manufacture lead chromate ourselves. . In fact, Sherwin "llliaas probably would view the latter with a certain ai.ount of complacency.

Daar Mr. Laist The following information briefly reviews my conversation of April 7th with representatives of The A. '.Vilhelm Company, Reading, Pennsylvania, concerning their interest in lead acetate and lead chromate production by the Sperry process. Upon my arrival at Reading I met with Mr. H. E. Graul, Production Manager; Mr. Hersch, Re3eerch Engineer and Mr. Whitman, Production Superintendent. In opening the conference, Mr. Graul stated that he wanted definitely to make clear two things; one, the Glidden Company dco3 not want to make white lead by the Sperry process; and two, that the request for information on the Sperry process was made by him without the knowledge of his superior officers, and he did not know whether they would approve or disapprove of his action. Since I did not know just what form the conference might teles, particularly as regards patent situations, I advised Mr. Graul that I was not authorized to speak on the question of patent or patent rights, and as far as I was concerned I would be glad to discuss his Interest in the Sperry process only as a basis for arriving at some satisfactory understanding of what they desired, and at some later time, depending on what circumstances might develop, the question of the legal and patent rights would have to be handled by the officers of the Anaconda Lead Products Company and their company. Their primary interest is obtaining a lead acetate solution which can be satisfactorily used for the production of chrome yellows, principally lead chranate. At the present time, they are making their lead acetate for this purpose from litharge produced by the Glidden Company, presumably the Metals Refining Company at Hammond, and acetic acid which is purchased locally. They are not satisfied with the -product produced by these materials, and believe that their difficulties are due to lack of control of the basicity of the lead acetate produced. . As nearly as I could determine, they are interested in producing at their- plant at Reading about 1,000 pounds per day of a suitable basic lead acetate. They were of the opinion that the Sperry cell would give them definite control of the basicity of the lead acetate produced-, and understood that in our white lead'process we 181 PNVC00008889 N11461.24 An a c o n d a Le a d Pr o d u c t s Co mp a n y Ka s t Ch ic a g o ',In d ia n a Sheet g-Z - Sir. i'rederialc Laist, Viee-?resLder.t May 29th, 192s first produced a basis lead acetate .and later precipitated the basic carbonate whits lead as a separate operation. With this understanding of the Sperry process, they had in mind the construction of a small experimental cell at Reading in which they could develop the operating conditions to produce particularly the lead acetate they desirei. They had the impression that an electrolytic cell for 1,000 pounds a day would create a very substantial power demand that might be prohibitive ae regards their limited power equipment, end also the economic factor of power cost. In discussing these factors with them I pointed out to them, Just as an illustration, that one of our white lead cells produces about 1,000 pounds per day of basic carbonate white lead, and the power requirements would be about 200 X.W.H. per cell. I also indicated to them the relative small dimensions of the cell, and they were impressed by the reasonable power requirements and the small floor space required for the cell. I attempted to obtain definite information as to the composition of the lead acetate solution desired, but they were either reluctant to give me this information or did not know definitely what composition wa3 best for their purposes. However, I suggested that if they preferred, they could study ^he question further and then if they thought it advisable give this information in a letter which could ce used by our Research Department to determine whether the"Sperry cell was adapted for this purpose. During practically all of the conference the discussion was limited to basic lead acetate, but in the latter part of the conference I brought out the point that the Sperry call would greatly simplify the sequence of step3 in the production of lead chromate, since the lead chromate could be made direct from metallic lead with a simple subsequent washing and drying operation. I brought out this possibility of the Sperry cell to anticipate the possibility that the Glidden Company might file an application for a patent to produce lead chromate by an electrolytic process which would he very similar to the Sperry cell. When 1 mentioned this possibility of producing lead chromate, Mr. Graul seemed very much surprised that the Sperry cell could do this as simply as indicated. Mr. H-oraah, their Research Engineer, however immediately realized the possibility and stated that that would be very simple, simply substitute the chromates for the carbonate salts used in the Sperry process and the product would be lead chromate. After a few moments Mr. -Graul saict "Well, if that is the case I nrat, in all fairness, ask if the Anaconda Lead Products Company can produce, with the Sperry call, lead chrcmate and it may be that your company would Ha s t Ch ic a g o ,In d ia n a Sheet ff5 - Mr. Frederick Lalst, Vice-President May 2Stn, 1936 want to go into the business of producing and selling lead chromates." I told him I could not answer that question because such a decision could only be made by the directors and not by myself. At that point I mentioned that the Sperry patents covered in general the production of any insoluble salt of metals, and presumably had anticipated a number of products such as lead chromate that might be made by this process. After leaving the conference and upon my return to Ea3fc Chicago, in reviewing the situation it was not exactly clear to me just where either the GllideD Company or the Anaconda Lead Products Company stood in this matter. As nearly as I could determine the interest of the staff at Reading was in producing a better grade of lead chromate. Mr. Graul's interest in asking about information on the Sperry process had in mind that this might be a far more satis factory method of eliminating their lead chromate troubles than attempting to proceed along the older and more established lines of chemical process methods. This plan would have the advantage that it could be investigated by the Reading staff, and if the results did not Justify further investigation the matter could be dropped without advising their superior officers. If, however, the possibilities appeared attractive they would be in a position to recommend the adoption of the Sperry process for this purpose. After my return to East Chicago I wa3 rather expecting a letter from Mr. Graul but X did not hear from him until I received the enclosed letter of May 1st in which Mr. Graul outlines in substance the thoughts I discussed with him while at Reading. You will note in this letter he makes no mention of the possibility of producing lead chromate which would to U3 he the most attractive use of the Sperry cell. There is considerable question whether a basic lead acetate solution can be produced in the Sperry cell because fundamentally it is designed for an insoluble salt production. There should he no advantage in the Sperry cell in producing lead acetate since the raw materials, that is, the lead and acetic acid presumably would have to be purchased at the same prices for the Sperry cell as -for any other chemical process. There might be a possibility of making lead acetate in the Sperry cell by the use'of calcium acetate in an absorption or reaction tower as a source of acetic acid, provided the residue of calcium hydroxide can be readily removed by filtration. This possibility would require some changes in the Sperry cell to adapt it for this purpose. The enclosed copy of letter from Mr. Graul gives more definite information on their requirements for basic lead acetate than 1 was able to obtain while at Reading. Ax a c o m)a Li;a d Pr o d u c t s Co mp a n y Ea s t Ch ic a g o ,In d ia n a Sheet jri - Mr. Frederick Laist,- Vic o-Fracident May 29th, 1936 I do not tel ieve it v.ould be advisable to advice the i'.'ilhela Company at this tine that the Sperry cell is not adapted for the production of lead acetate. I believe the staff at Reading is interested enough in the possibilities cf either the production of an electrolytic lead chromate or basic lead acetate to make some experiments alone this line, i'.'e are preparing a patent application for the production of lead chromate by the Sperry cell, and therefore it would be advisable to avoid any definite decision with the Wilhelm. Company until our patent application has been filed. In the interval, we are recovering a substantial amount of lead acetate from our slime plant operations, and as soon as our Research Department has the time available we plan to determine the percentage of basic lead acetate present and the possibilities of preparing some samples of basic lead acetate, which we might- forward to the Wilhelm Company in order to clearly establish for our information the proper basicity of their solution for lead chromate production. This work would he a step in the right direction if we have any further interest in the possible production of lead chromate, and would also assist us in understanding the problems of our white lead customers who use white lead for the production of lead chromate and other color materials.

Since this question has been called to our attention, we have been thinking over the possibilities of using the Sperry cell for the production of lead acetate.
