- specification.
My invention relates to the class of electric lamps in which the light emitting element or member is a non-conductor at ordinary temperatures and which may be made conductive by subjecting it to a relatively high degree of heat.
The object of my invention is to provide a light emitting member or glower of such composition of materials as shall speicially adapt it for eflicient service and long ife. I have found that a glower formed of as mixture of certain materials will become conductive at a lower temperature and be more durable'in service than aglower made of a single material, provided the materials are thoroughly powdered and mixed together, then combined with a suitable binding material, and formed into the proper shape and thoroughly baked, suitable terminals of conducting material being attached to the ends of the glower in order to facilitate connecting it in circuit for operation.
My invention contemplates the employment of any one of a considerable variety of mixtures of materials, but mixtures of two or more of the oxids of zirconium, yttrium, thorium, beryllium, and magnesium will generally be found most desirable. ll may, however, combine one of these oxids, such, for example, as the oxid of magnesium, with a small percentage of boric acid, chlorid of calcium, tungstic acid, or the like.
When a glower formed of a proper mixture of two or more of the materials above specified is connected in an electric circuit cium and oxyg and heated to its conducting temperature, the heat developed in itself by the passage of a current therethrough will serve to maintain it in a conducting condition and cause it to yield light in a very eficient manner.
As an illustration of my invention, 1 show, in the accompanying drawing, a glower 1 which is a non-conductor at ordinary temperature. As a simple means for raising the glower to conducting tempera: tures, I show a torch 2 supported upon a suitable base 3.
llt is to be understood that the illustration is in no sense restrictive,,as regards either the form or dimensions of the glower or the means employed for heating it to conducting temperature.
This ap lication is a division of my application filed December 19th, 1906, Serial Number 348,567, issued as Patent, Number 1,071,649, August 26, 1913, which is a division of iny application March 29th, 1898, Serial Number 675,603, issued October 6th, 1908, as Patent 900,416 and another division thereof is application filed September 10th, 1908, Serial Number 452,485.
I claim as my invention:
' 1. A homogeneous conductor for electric lamps containing intimately mixed calcium and tungsten in the form of compounds.
2. A light giving body for electric lamps, comprising intimately mixed tungsten, cal- 3. A radiant body comprising intimately mixed calcium and a metal and oxygen.
4.. An illuminant for electric li hting comprising intimately mixed the oxlds of calcium and tungsten.
Signed at Berlin, Germany this 17 day of March, A. D. 1913.
