5 Claims. (Cl. 250-34)
Our invention relates to Roentgen apparatus former wherein the ring-like secondary winding
and is more speci?cally concerned with a novel
and improved unitary vstructure wherein the
is taped and the iron core grounded in usual
manner causes difficulties because one pole of
Roentgen tube, the high tension transformer
the high tension transformer must be electrically
,6 and the heating transformer, which is spaced
therefrom and connected to high tension, are
provided in a common housing and wherein the
secondary winding of these separately placed and
spaced transformers are united by a common in10 sulating means to form a unitary and common
structure.
A brief review of the reasoning underlying our
invention with reference to the prior art is
rendered below so that its various objects and
advantages will be readily understood.
It is the aim in structures such as noted above,
namely, in Roentgen apparatus wherein the
Roentgen tube, the high tension transformer and
also the heating transformer connected to high
20 tension are provided in a common housing, to
connected with the heating winding. This con- .
C31
nection as such would have to be taped also.
According to the invention, the resulting dif?
culties, as intimated above, can be greatly re
duced and the taping can be considerably simpli
?ed by connecting through a common insulating if’
bandage or tape the secondary winding of the
heating transformer, and at least that part of
its iron core surrounded thereby, with the sec
ondary winding of the separately disposed high
tension transformer to form a unitary structure i=1?
therewith. Inasmuch as the high tension
carrying taped part of the heating transformer
forms then a unit with the secondary winding
of the high tension transformer through the
common taping, we obtain the same advantage ".0
keep the weight and the dimensions of the ap-
that results in apparatus wherein the heating
paratus as small as possible. In order to realize
winding is provided directly upon the iron core
this aim, the secondary" winding of the high
of the high tension transformer. The Roentgen
tension transformer is provided with an insulat25 ing means, e. g., a suitable bandage or taping,
and the conductor means leading from the high
tube tension and current can also be separately
regulated.
The invention will be better understood from .%'
tension transformer to the Roentgen tube, and
in certain instances parts of the tube, are also
insulated against‘ the grounded wall of the hous30 ing by ‘an insulating provision which may be
a bandage consisting of paper tape.
It may be mentioned at this point that the
terms “insulating bandage” or “insulating tape
or taping"- and equivalent language, as used
35 herein, are intended to convey insulating means
the detailed description which is rendered below
with reference to the accompanying drawing,
wherein
Fig. 1 shows one embodiment of our invention ‘30
in schematic representation; and
Fig. 2 illustrates a modi?cation.
Like parts are designated by like reference nu
merals throughout the drawing.

wrapped around or provided on the respective
parts in a suitable manner so as to form thereon
the grounded housing or casing containing the
Roentgen tube 2 with its anode grounded as
'
an insulating layer or layers or an insulating
covering of a sort which is suitable for the purpose in view. These terms are, therefore, not
used to indicate undue limitations. In their
broadest sense they should be construed simply
as denoting “insulating means”, regardless of the
speci?c material of which this means consists
and- the manner in which it is applied. Paper
is mentioned herein for an insulating material,
but other materials may be used if desired.
The heating transformer is generally accommodated in such apparatus by disposing the
heating winding directly upon the iron core of
the high tension transformer. This is, however,
impossible, for example, in apparatus of considerable output, wherein a separate regulation
of the Roentgen tube tension and current is required. The placing of aseparate heating trans~
shown, the high tension transformer with its
primary winding 3, secondary winding 4 and
the iron core 5. The secondary winding 4 is in— 40
sulated by means of paper taping 6 which also
surrounds the conductor means 1 leading to the
Roentgen tube 2. The secondary winding 8 of
the separately placed open core heating trans
former is included in the common taping 6 to- .45
gether with its iron core 9 which is electrically
connected with the secondary winding 8. The
primary winding ID of the heating transformer
is slipped over the taped part of the structure.
If required, the iron core 9 may be continued 50
outside of the taping, resulting in a heating
transformer with an almost closed iron core.
In the embodiment shown in Fig. 2 the taped
part of the heating transformer forms a pro
tuberance on the common insulating taping 6 55
