To (LZZ whom it may concern:

it known that I, CARI, Aunu vox Wins- Bxon, a subject of the 'l lmperor of Austria, rcsiding at \"icnna,in the Empire ofAustriallungary, have invented new and useful Improvements in Incandescent Burners for Gas, (for which I have obtained patents in l ranceulated November-4, 1885, No. 172,064; Belgium, dated November 4, 1885, No. 70,789; Italy, dated February 23, 1886, Vol. XXXVIII, No. 310; France, Certificate of Addition, dated April 22, 1886, No. 172,064; Belgium, Certificate of Addition, dated September 9, 1886, No. 74,502; Spain, dated Augustl 0, 1886,1fl'o. 9, 031/ 5,858; Italy, Certificate of Addition, dated October 13, 1886, Vol. XL, No. 415; Finland, dated July 10, 1886, No. 261; Norway, dated August 25, 1886, No. 88; Victoria, dated March 17, 1886, No, 4,472; New South Wales, dated llay 11, 1886, No. 1,829/2; Tasmania, dated March 24, 1886, No. 898/9; Queensland, dated June 28, 1886, No. 106; New Zealand, dated June 11, 1886, No. 1,863; Cape of Good Hope, dated March 4, 1886, No. 6/205; India, dated September 2, 1886, No. 40/ 1,145; South Australia, dated May 3, 1886, No. 678; Great Britain, dated Novemberat, 1885,No. 13,3162 and December 12, 1885, No. 15,286, and Great Britain by application for patent dated March 18, 1886, No. 3,592,) of which the following is a specification.

It has heretofore been proposed to use refractory earth and platinum or other wires or filaments made of infnsible n1aterialsuch as magnesia in the manufacture of devices adapted to be heated to incandesccnce by the name from a gasbnrner, such devices being now known in the art as incandescent burners, for the purpose of increasing the illuminating-power of gas.

My invention has for its object to provide a novel compound for making durable and efficientincandescent burners for gas; and to such end it consists in the combined properties of oxide of lanthanum, oxide of yetrium, and oxide of zirconium, which I have discovered to be very valuable as an illuminant when rcndered incandescent by the flame from a gasburncr. The combined properties of these oxides in a finely-divided condition produce the following results: First, if heated by the flame from any ordinary gas-burner, ahighlyintense, almost white, light is obtained; second, the substances are incombnstible and infusiblc, and do not volatilize; third, the suit stances do not produce scale or ash after burniug several hundreds of hours, nor do they evince any decrease of power of oinitlance, but remain altogether perfect; fourth, the substances can without any change be exposed for any length of time to the influence of atmospheric air so long as the latter is in a condition for inhalation.

The proportions of the oxides may be varied; but I have found the following to give very satisfactory results where all three of the oxides are employed, to Wit: oxide of zirconium, sixty per cent.; oxide of lanthanum, twenty per cent; oxide of yctrium, twenty per cent.

The combined substances may be employed in connection with gas-burnersin various Ways. For example, the burner may be composed of a tubular skeleton hood, cap, or frame suspended over the flame of the gasbnrner, so as to become heated by such flame to incandcs cence, causing it to give out great and brilliant light. The hood may be made of light net-work fabric or threads-such as cotton impregnated with a solution of the salts of the combined substances named and then exposed to heat,

It is hereby certified that in Letters Patent No. 359,524, granted March 15,1887,

upon the application of Carl Auer von Welshach, of Vienna, Austria-Hungary, for an improvement in Gaslncandescent, errors appear in the printed specification requiring correction, as follows: On page 1, in lines 44 and 68, and on page 2, 1iues 10 and 15,

the word yetriutn should read yttrium and that the Letters Patent should be read with these corrections therein that the same may conform to the record of the ease in the Patent Oflice.
