To the Editor
In the article by J. E. Bates and I. V. Runyan, which appeared in the July, 1949, issue of the JOURNAL, the regeneration of Ansco Color bleach solutions by the use of liquid bromine is disclosed (pp. 16-17). We believe it is only fair to your readers to inform them of the legal situation regarding the use of liquid bromine in bleach regeneration. The method is the subject of a patent application assignable to Pavelle Color Incorporated. (Tne term liquid bromine is stressed to distinguish from bromine water which had been tried by others and discarded because of bath dilution.) Before anyone spends time and money installing this process, he should know that its use may not be entirely free.
We have delayed publishing our data and experience on bleach regeneration pending patent-office action on our application, but will prepare a paper in the near future.
The article by A. H. Brunner, Jr., P. B. Means, Jr., and R. H. Zappert in the same issue contains a statement which we believe to be incorrect. They state on page 30 that the colorimetric method of Varden and Seary (/. Soc. Mot. Pict. Eng., vol. 47, pp. 450-453; December, 1946) for ferrocyanide determination is not sufficiently accurate for bromine regeneration. For over three years we have controlled the regeneration of thousands of gallons of bleach by the colorimetric method. Even with the crude apparatus described in our article, it is easy to determine the ferrocyanide concentration within an accuracy of plus or minus 0.03 per cent. We have found this to be entirely adequate.
