I EMILE SERVAIS, Weilerbach, Grand duchy of Luxembourg do hereby declare the
nature of this invention to be as follows :-
This invention relates to improvements in ellipsoidal or similar converters. For the
purpose of keeping the molten metal at a sufficiently high temperature without much
loss of metal and to burn the metalloids or non metallic elements at the same time, the
blast pipes are arranged in several rows one above the other.
The form or shape of the converter may be very nearly the form of a rotation
ellipsoid formed by the rotation of an ellipse round its smaller axis. The circular
form of the two sides can also be flattened a little so as to give them an elliptic form.
The converter turns round a horizontal axis one of the trunnions being hollow to
introduce the blast into the tube and the blast box and thence through blast pipes or
holes into the interior of the converter. These blast pipes are arranged alternately
opposite each other in the sides of the converter and in consequence of a fan like
direction or arrangement the blast will reach every part of the molten metal.
The blast pipes can also be arranged in several rows above each other which
arrangement has the double advantage to burn the metalloids at the same time in the
whole of the molten metal diminishing thereby the waste and materially increasing
the temperature. Instead of in the flat sides the blast pipes may be arranged in the
cylindrical part of the converter.

page_text: 1, EMILE SERVAIS, Weilerbach, Grand duchy of Luxembourg, do hereby declare
the nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to improvements in ellipsoidal or similar converters. For the
purpose of keeping the molten metal at a sufficiently high temperature without much
loss of metal and to burn the metalloids or non-metallic clements at the same time the
blast pipes are arranged in several rows one above the other.
Fig. 1 and 2 in the accompanying drawings represent a vertical section and side
elevation of an ellipsoidal converter.
Fig. 3 is a horizontal section showing the peculiar position of the blast pipes.
Fig. 4 represents another arrangement of the blast pipes.
The form or shape of the converter A represented in Figs. 1 and 2 may be very
nearly the form of a rotation ellipsoid formed by the rotation of an ellipse round its
smaller axis. The circular form of the two sides can also be flattened a little so as to
give them an elliptic form as in Fig. 4.
The converter turns round a horizontal axis B one of the trunnions being hollow to
introduce the blast into the tube V and the blast box W and from thence through the
blast pipes or holes W¹ (Fig. 3) into the interior of the converter. These blast pipes
are arranged alternately opposite each other in the sides of the converter and in
consequence of a fan like direction or arrangement the blast will reach every part of
the molten metal.
The blast pipes can also be arranged in several rows above each other as shown in
Fig. 4 which arrangement has the double advantage to burn the metalloids at the
same time in the whole of the molten metal diminishing thereby the waste and
materially increasing the temperature. Instead of in the flat sides the blast pipes
may be arranged in the cylindrical part of the converter.
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same may be performed I declare that what I claim is ;-
1. A converter, the form or shape of which is formed by the rotation of an ellipse
or a similar curve around its smaller axis or being an ellipsoidal with 3 axes
substantially as specified.
2. In a converter the arrangement of the blast pipes in the sides in several rows
one above the other for the purpose of burning all the metalloids in the converter
simultaneously.
