handle is hein.usfed/usatoemre0010 and id is 1 raw text is: May 29, 1956 Vol. VI No. 3 The following U. S. Letters Patent owned by the United States Atomic Energy Commission have been made available for licensing by the Commission. Licenses will be granted to applicants on a non-exclusive, royalty-free basis. Applicants for licenses should apply to the Chief, Patent Branch, Office of the General Counsel, U. S. Atomic Energy Commission, Washington 25, D. C., identifying the subject matter by patent number and title. Patent No.: 2,737,779 Title: Condensable Vapor Extraction Apparatus Issued: March 13, 1956 Inventor: E. 0. Lawrence This patent relates to a device for obtaining a very high vacuum in a large tank. The pumping out operation is considerably ex- pedited when the vacuum pump is augmented by a condensable vapor extrac- tion trap. This trap, containing a coolant such as liquid air or liquid nitrogen, located in the tank condenses out much of the contained vapor, thereby substantially halving the time required for pumping out. Here- tofore, these traps containing the condensed vapors have remained in the tank necessitating the constant addition of coolant to keep the vapors condensed. This device permits the removal of such a trap after the desired vacuum has been obtained and seals the opening after removal thus eliminating the need of constantly adding the expensive coolant during the period the vacuum is maintained, which may be many days. Patent No.: 2,738,346 Title- Method for the Separation of Flavonoid Compounds Issued: March 13, 1956 Inventors: S. H. Wender, C. H. Ice This patent relates to an improved method of separating closely related flavonoid compounds. The method comprises passing a solution of the compounds, such as a mixture of xanthorhamnin, rutin, and quercetin dissolved in a low molecular weight anhydrous aliphatic organic solvent, such as acetone, through a column of comminuted hydrous magnesium silicate adsorbent, then chromatographically eluting the resulting adsorbed compounds from the silicate material by means of an aqueous relatively low molecular weight organic solvent, such as an ethyl acetate solution saturated with water and containing a trace of acetic acid, and separately collecting the resulting individual flavonoid compounds.
