ELECTRIC VAPOR-LAMP AND THE LIKE.
Specification of Letters latent.
Application filed September 25, 1914. Serial No. 863,565.
. lowing is a specification.
This invention relates to electric vapor lamps and the like.
It is well known that for certain purposes the electric arcs in such apparatus have to be electromagnetically controlled, see for instance my application Serial No. 854457. This can readily be efi'ected in the case of lamps or the like in glass vessels but not so when the are contained in metal vessels, because e dy currents will be introduced in the metal wall and in other ways the magnetic flux will be prevented from influencing the are.
The present invention has for its object to provide an apparatus for magnetically infiuencing an electric arc in a metal vacuum vessel wherein the aforesaid injurious effects will not take place.
The invention consists in so constructing and disposing the magnet that penetration of the metal wall by lines of force is almost Wholly avoided, for example, byarranging' the blowing magnet entirely inside the metal vessel.
In the accompanying diagrammatic drawings: Figure 1 shows a sectional elevation of one form of the present invention; Fig. 2 is a section on the line 2-2 of Fig. 1 looking in the direction of the arrows; Fig. 3 is a sectional plan of a modification (on the line 3-3 of Fig. 4), and Fig. I is a sectional elevation corresponding thereto. Fig. 5 is a section on the line 55 of Fig. 4. Fig. 6 is a sectional elevation of a iurther modification. Fig. 7 is a sectional plan of Fig. 6 on the line 7-7, and Fig. 8 is a section on the line 88 of Fig. 6.
In Figs. 1 and 2 the magnet m is arranged wholly inside the vessel g. Thus the flux of the magnet does not pass through the metal wall so that the aforesaid injurious efi'ects do not take place. In this form the electric arc is led through a glass, porcelain or like electrically non-conducting tube m for the purpose of keeping theelectric arc and the mercury vapors away from the winding of the magnet, which winding is preferably formed of enameled wire. Then the electric arc is led through a glass tube or the like,
this by concentration will be favorable to the action of the magnet. The glass tube will not be exposed toa one-sided pressure, because there is a vacuum both inside the tube and in the space surrounding said tube.
WVhile any connections or arrangements may be used for producing the light arc indicated by Zit only being necessary for the present invention to assume that such are is there-the arrangement referred to above is applied in an apparatus as shown in Fig. 3 of my copending application No. 854457. In this case the arc is produced between mercury electrodes 9 in the glass cell :0 containing mercury vapor under diminished pressure. The electrodes are connected to a battery e and primary of a transformer "3 The winding "L0 is excited by the alternator Z. The apparatus of Figs. 3 to 5 comprises a metal vessel 9 containing in its interior a sheet partition 8 and of a further vessel d which carries two mercury electrodes 9, q, and the electromagnet m including the poles 79 p and the winding w. By the action of the magnet the electric arc is blown against the edge of the partition 8 and into the space a, c.
In Figs. 5 and 6 the yoke and the winding w of the magnet m are situated outside the metal vessel, and only the poles are brought into the interior of the vessel. In order however, to prevent the occurrence of eddy currents in the metal wall g, it is formed with a slot at between the arms of the magnet. The aperture is closed by means of a nonconducting material. The resulting field in the aperture of the metal wall thus formed is then m'l.
A. partition .9 as shown in Fig. i may be used in other forms, for example, that shown in Figs. 5 and 6.
