To all whom it may concern: Be it known that I, GUITHOLD EPHRAIM'.
*WnRrHnnane, a subject of the Emperor of Austria, and a declarant of the United States of America, having applied for first papers in March, 1917, residing at 531 First avenue, Astoria, borough of Queens, in the county of Queens and State of New York, have invented certain new and useful Improved Solutions or Baths for Use in Electrically Preparing Stencillates, D 1e-' Plates, and the like, of which the follovvmg is a specification,
This invention relates to a composition of matter adapted to be used as the solution or bath in connection with a process of preparing metallic stencil plates or dle plates or blocks or like articles, involving the erosion or eating away of certain parts of such plates by the use of electric current in conjunction with said solution or bath.
The object of the present invention is-to de a solution or bath which will enable e expeditiously applied to toned metals, such as steel, or die plates or blocks h annealed or hardened metals oduced at a low cost and ails producing a uniform was on the remaining poror I he improved solution or bath according to the present invention comprises a mixture of sulfuric and nitric acids, ammonium IiEHlOVE chlorid and water, with a small proportion -39 of acetic acid. Elhese ingredients are preferably employed in the proportions of eighty parts of sulfuric acid twenty parts of nitric acid, two hundred parts of ammonium chlorid, two parts of acetic acid and six hundred and ninety eight parts 0 Water.
In preparing the solution, granulated ammonium chlorid is firstly dissolved in Water, at approximately the boiling point in substantially the proportion of one pound of ammonium chlorid to one gallon of Water. By' this means a saturated solution of ammonium chlorid is obtained. The other ingredients are mixed together in substantially the proportions stated, the solution of ammonium chlorid prepared as described, in substantially the proportion given above is added thereto, the entire mixture being thoroughly stirred to secure an intimate admixture of the various ingredients.
The resulting solution is then preferably heated to a temperature of approximately eighty-three degrees Fahrenhcit and main" tamed at about that temperature during the operation of the process, by any suitable electrical or other means. The solution may, of course, be cold but is found that the best results are obtained when the same is kept at the temperature mentioned while the process is in operation.
The accompanying drawing diagrammatically indicates the manner in which the solution may be used in the treatment of a metallic plate or block from which a stencil plate or die plate is to be prepared.
The metallic plate or block 1 be operated on is immersed the solu or bath 2 contained in a su 3 and an electric cunt is passed through the p as an anode and tlirou suitable cathode 1, parts of the plate a resisting coating oi suit-ab rapidly eroded or cut y. have been made with to the temper l i using an elect. volts about to been found possible to out hardened steel to a depth hree sixtyfourths of an inch in one hour over an desired configuration. The great utili'y or this solution or bath for the purpose sated Will thus be readily reco 'niaed.
l have found that i of the acetic acid to the other ingredients of the solution tends to reduce the erratic action of the solution on the metal and to increase the uniformity and smoothness of the surfaces produced thereon.
