Total.-....--. 1,382 Disclaimers 1,410,49.--Aladar Paco, Cleveland, Ohio. METAL AND ITS MANUFACTURE. Patent dated March 21, 1922. Dis- claimer filed November 10, 1933, by the assignee, General Electric Company. Therefore enters this disclaimer to so much of the statement on lines 52 to 59 of page 2 of the printed patent specification as might imply or tend to imply that by adding a solution of boric acid to chemically pure WOs, evaporating, drying, Igniting and reducing alone, it Is possible to produce commercially useful non-sagging and non-offsetting tungsten filaments. 1,796,431.-Arthur 0. Austin, near Barberton, Ohio. MEANS FOR DIVERTING ENERGY FROM HIGH POTENTIAL CONDUCTORs. Patent dated March 17, 1931. Dis- claimer filed November 8, 1933, by the assignee, The Ohio Brass Company. Hereby enters this disclaimer to that part of the claims in said specification which is in the following words, to wit, 2. The combination with a current transformer, of a corrective winding for said transformer, and means for energizing said corrective winding comprising a conductor having current therein out of phase with the current In the primary of said current transformer. 13. The combination with a current transformer, of a corrective winding for said transformer, and means for energizing said corrective winding comprising a conductor and a source supplying voltage to said conductor out of phase with the voltage Impressed on the primary winding of said current transformer but having a definite phase relation therewith. 1,835,118.-John W. Marden and Ernest A. Lederer, East Orange, N. J. ALKALI METAL TUBE. Patent dated December 8, 1931. Disclaimer filed November 4, 1933, by the assignee, Westinghouse Lamp Company. Therefore, enters this disclaimer to that part of said specification and claims which are in the following words, to wit: 1. The steps in the method of producing a thermionic discharge device employing a caesiated cathode which comprises Introducing into the device a mixture of a re- ducible compound of caesium and a compound of another alkali metal of lower atomic weight with a reducing agent and heating the mixture to liberate the alkali metals in the device. 2. The method of activating a metallic cathode for electron emission purposes and cleaning up residual gases and vapors in an electron discharge device of the caesiated cathode type, comprising heating to reaction temperatures in the device a mixture of a compound of caesium and a compound of potassium with a reducing agent to liberate these metals in the device. 3. The steps in the method of producing a thermionic discharge device employing a caesiated cathode which com- prises liberating in the device from chemical compounds of which they are elements a quantity of caesium and another alkali metal which forms more stable compounds with hydrogen than does the caesium. 4. The steps in the method of producine a thermionic discharge device employing a caeslated cathode which com- prises liberating in the device from chemical compounds of which they are elements a quantity of caesium and potassium. 8. A getter for electron discharge devices employing caesium therein, comprising a mixture of a compound of caesium and a compound of another alkali metal of lower atomic weight mixed with a reducing agent. 9. A getter for electron discharge devices employing caesium therein, comprising a mixture of a compound of caesium and a compound of potassium mixed with a re- ducing agent. 1,836,d31.-Hakon H. Hagland, Flushing, N. Y. Con- RECToR SYSTEM FOR SYNCHRONOUS TELEGRAPH APPA- RATUS. Patent dated May 3, 1932. Disclaimer filed November 2, 1933, by the patentee, assignee, The Western Union Telegraph Company, assenting. Hereby enters a disclaimer to that part of the subject- matter of his said Patent No. 1,856,331, defined in claims 1, 2, and 5 thereof. 1
