To aZZ 'whom traag Concern.' 'Y l Be it known that I, HARLAN L. TRUMBULL `citizen ofthe United States, residin at Seattle, in the county of King and tate of Washington, have invented certainne'w and useful Improvements in Processes of Producing Alkalis from Kelp, of which the following is a specification'll Myfinvention relatesto a process for the production'of alkalis from kelp by the employmenty of a method known as. electrical endosmose and 'has for its object to vaiford a processwhereby the referred to alkalis mayy befobtained more expeditiously and 1.5; cheaply thanu hitherto. ,A further object is `to furnish compounds of potassium more valuable than those commonly derived from kelp.
The invention consists in the novel process herein-after describedand claimed.`
The apparatus by which myinventionis attained, is illustratedfin the accompanyingl drawings, in which-Figure lis a plan view, Vand Fig 2`is atransverse vertical section through 1- 1 of Fig. 1. f
