ELECTRICAL DISCHARGE DEVICE

Application January 23, 1936, Serial No. 61496
23 Claims. (Cl. ‘176-122)
This invention relates to improvements in elec
trical discharge devices of the kind commonly
used for illuminated signs and other purposes‘,
consisting of a closed glass tube containing a- gas
5 or vapor, or both, through which a high tension
electrical discharge is passed to produce a lumi
nous e?ect. In my application, Serial Number
691,551, ?led September 29, 1933, I have shown
surface of the tube, a capacity circuit is- con
structed, the wall of the tube acting as the di
electric and the outer conducting-material and
the electri?ed gas forming the two conducting
mediums of a condenser. The external capacity 5
circuit a?ects the electrical charge present in the
area to which it is applied, while the current is
flowing.

. In the accompanying drawing, I have shown
such a, device in which a part of the tube contains
10 a ?ller of insulating material which causes the
discharge to take a tortuous course through the
tube and a?ords a plurality of paths for the dis
discharge tubes with the external electrically c‘on- 10
ductive medium variously arranged, for the pur
charge, and in the operation of that device the
course of the discharge through that part of the
15 tube containing the ?ller constantly shifts, owing
to changes-inthe resistance of the gas due to
heating, the current taking the course of least -_
vice containing a ?ller and having relatively small 15
areas at the ends of the portion of‘the tube con
pose of illustration.
The present invention applies to tubes of the
2Q kind referred to in the aforesaid application and
embodies means external to- the tube for control

in the tube, this means consisting of what might
be termed an external capacity circuit which af
