Year: 1883

page_text: LETTERS PATENT to Astley Paston Price of 47 Lincolns Inn Fields in the
County of Middlesex, Gentleman for an Invention of "IMPROVEMENTS IN THE
MANUFACTURE AND PRODUCTION OF OXIDE OF ZINC"
PROVISIONAL SPECIFICATION left by the said Astley Paston Price at the
Office of the Commissioners of Patents on the 21st November 1883.
ASTLEY PASTON PRICE of 47 Lincolns Inn Fields in the County of Middlesex,
Gentleman, "IMPROVEMENTS IN THE MANUFACTURE AND PRODUCTION OF OXIDE
OF ZINO"
This Invention relates to the manufacture and production of Oxide.of Zinc and
consists: Firstly, in submitting to the action of a Blast Furnace Cupola or other
suitable furnace, ores, compounds or products containing zinc, in order that, during
their passage through such or similar furnaces, the zinc contained therein may be
volatilized therefrom, and its separation be effected either in the manner as
described in the Provisional Specification applied for by me for Improvements in
the manufacture and production of Zinc dated 16th November 1883 or otherwise
and then converting the metallic zinc thus obtained by calcination and oxidation
in a suitable furnace into oxide of zinc. Secondly, in effecting the combustion and
oxidation of the volatilized zinc contained in and mixed with the products of
combustion and the combustible gases by causing such products and gases to be
conducted into suitable combustion chambers in which their combustion and
oxidation may be effected and so constructed as that the oxide of zinc thus formed
may be conducted by an exhaust or otherwise into properly constructed chambers
in order that the oxide of zinc thus formed may be collected and the gaseous
products of combustion be allowed to escape.
The oxide of zinc resulting and obtained by either of these methods may be
employed as a pigment or for other purposes useful in the arts.

ASTLEY PASTON PRICE of 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman "IMPROVEMENTS IN THE MANUFACTURE AND PRODUCTION OF OXIDE
OF ZINO"
This Invention relates to the manufacture and production of Oxide of Zinc and
consists in firstly submitting to the action of a blast furnace cupola or other suitable
furnace ores compounds or products containing zinc either before or after calcination
in order that during their passage through and treatment in such or similar furnaces
the zinc contained therein may be volatilized therefrom and its separation be
effected either in the manner as described in the Specification of Letters Patent
Number Five thousand four hundred and sixteen granted to me for "Improvements
in the manufacture and production of Zine" dated sixteenth November One
thousand eight hundred and eighty three or otherwise and then effecting the
combustion and oxidation of the volatilized zinc contained in and mixed with the
gaseous products of combustion by causing such products to be conducted into
suitably arranged and constructed combustion chambers in which their combustion
and oxidation may be effected and such combustion chambers being so constructed
as that the Oxide of Zinc thus formed may be conducted by an exhaust or otherwise
into properly constructed chambers or collectors in order that the Oxide of Zinc
thus formed may be collected and the gaseous products of combustion be allowed
to escape.
The Oxide of Zinc thus resulting and obtained may be employed as a pigment
or for other purposes useful in the arts.

Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the Invention secured to me by the hereinbefore în part
recited Letters Patent is :-
The manufacture and production of Oxide of Zinc by effecting the combustion
and oxidation of metallic zinc contained in the combustible and other gaseous
products arising from the treatment of Ores compounds or products containing Zinc
in the manner as herein before referred to.
In witness whereof I the said Astley Paston Price have to this my Specification
set my hand and seal this twentieth day of May One thousand eight hundred and
eighty four,
