Improvements in Size.
A communication from abroad by ALPHONSE KRIZEK and ROBERT ESCHÉ, both
of Geneva, in the Republic of Switzerland, Chemical Analysts.
I JOB SHEPHERD of 16 Dayton Grove Peckham in the County of Surrey do
hereby declare the nature of this invention to be as follows :-
This invention relates to a mineral size which can be used for whitewashing
painting and all other purposes in which animal size is now usually employed.
To make this mineral size I employ the following ingredients which (taking the
total quantity as 100 kilos.) I use in the proportions hereinafter mentioned.
I take kilos. 4.375 of amidon and kilos. 93-875 of water and moisten the amidon
with part of the water. I then add kilos. 0.100 of acid of salicylicum to which I
add in small quantities (stirring the mixture at the same time) kilos. 1-375 of natrum
hydricum causticum (hydrate of caustic soda) I then add little by little the rest of
the water at the same time stirring the mixture. 1 then add kilos. 0.150 of
chrysoiden & when this is well mixed with the other ingredients I further add to
the mixture kilos. 0.125 of ether (spiritus aetherus). The whole of the ingredients
are used cold and the mixture can be made by the means of an ordinary mixing
machine or in any other suitable manner.
Dated this 21st day of July 1891.
Improvements in size.
A communication from ALPHONSE KRIZEK and ROBERT ESCHE, both of Geneva,
in the Republic of Switzerland, Chemical Analysts.
I, JOB SHEPHERD of 16 Dayton Grove, Peckham in the County of Surrey, do
bereby 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 a size which can be used for whitewashing, painting,
and all other purposes in which animal size is now usually employed, a single coat
of the new size producing the same effect as 2 to 4 coats of the animal size.
To make this size 1 employ the following ingredients which (taking the total
quantity as 100 kilos.) I use in the proportions hereinafter mentioned.
I take kilos. 4-375 of amidin and kilos. 93-875 of water and moisten the amidin
with part of the water. I then add kilos. 0.100 of acid of salicylicum to which I
add in small quantities (stirring the mixture at the same time) kilos 1-375 of
natrum hydricum (hydrate of soda) I then add little by little the rest of the water
at the same time stirring the mixture. I then add kilos. 0-150 of chrysoidin and
when this is well mixed with the other ingredients I further add to the mixture
kilos. 0.125 of ether (spiritus aetheras). The whole of the ingredients are used
cold and the mixture can be made by the means of an ordinary mixing machine or
in any other suitable manner.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondents, and in what manner
the same is to be performed, I declare that what I claim is :-
:-
The size made in the manner and of the ingredients and in the proportions
substantially as specified.
