PROVISIONAL SPECIFICATION.
Improvements in Manufacturing Nickel Alloys.
I, LUDWIG MOND, of Winnington Hall, Northwich, in the County of Cheshire,
Manufacturing Chemist, do hereby declare the nature of this invention to be as
follows:-
This invention consists in the manufacture of nickel alloys such as nickel steel,
German silver, etc., etc., by means of a compound of nickel with carbonic oxide
called nickel-carbon-oxide.
This compound is a colourless liquid at ordinary temperatures, boils already at
43° C. and is very readily volatile at ordinary temperatures in a current of other
gases. It is also soluble in a large number of other bodies such as petroleum oils,
tar oils, etc.
In order to produce alloys of nickel the metal or metals to be alloyed with
nickel are melted, and nickel-carbon-oxide is then introduced into the molten
metal or metals, when the compound is immediately decomposed, carbonic oxide
escapes, and the nickel combines with the fused metal or metals forming the
desired alloy.
The nickel-carbon-oxide may be employed in the gaseous state, either pure or
mixed with other non-deleterious gases, such as it can be obtained direct from
nickel ores or other substances containing nickel by acting upon these with carbonic
oxide gas, or the substance may be employed in the form of the pure liquid or in
the form of a solution of this liquid as hereinbefore mentioned.
Dated this 11th day of May 1891.

COMPLETE SPECIFICATION.
Improvements in Manufacturing Nickel Alloys.
I, LUDWIG MOND of Winnington Hall, Northwich in the County of Chester,
Manufacturing Chemist, 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 :-
In my Specification No. 12626 of 1890, I set forth a method of manufacturing
metallic nickel by means of a compound of nickel and carbonic oxide called nickel
carbon oxide.'
The present application is for a variation of this method by which metallic
nickel is obtained in combination or alloy with other metals.
In order to produce the alloys of nickel, the metal or metals to be alloyed with
the nickel are melted and nickel carbon oxide is then introduced into the molten
metal, is passed over it or otherwise brought into contact with it. The nickel
carbon oxide is thereby immediately decomposed. The carbonic oxide escapes,
and the nickel combines with the fused metal, and at once forms the desired alloy.
In cases where there are two or more metals alloyed with the nickel, I may melt
one of these, pass the nickel carbon oxide through it, and afterwards add the
remaining metal or metals.
In carrying out my invention, I employ the nickel carbon oxide in the gaseous
state and preferably mixed with other non-deleterious gases. In practice it is
most advantageous to make direct use of the gases as they are obtained in extracting
го

carbonic oxide under my before mentioned Patent No. 12626 of 1890.
I either pass these gases over the surface of the molten metal or metals con-
tained in a suitable vessel or I introduce them under the surface of the molten
metal in the well known way in which air is introduced into a Bessemer converter,
or by suitable tubes or tuyères. These tubes or tuyères must be kept cool by
water or other means, to prevent the formation of a deposit of nickel in them,
which might block them up.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is--
The manufacture of alloys of nickel with other metals by bringing nickel carbon
oxide into intimate contact with the molten metal or metals.
