Improvements relating to the Treatment of Peat.
I, EDOUARD RISCHGITZ, of Cambridge Lodge Studios, Linden Gardens, Bayswater,
in the County of Middlesex, Artist Painter, do hereby declare the nature of
this invention to be as follows:-
As described in my Complete Specification No. 10452 A.D. 1891, I have
hitherto used hydrate of lime in clear solution for making peat fuel, but I have
found in practice that this necessitates too much water being used as the percentage
of lime taken up by the water is comparatively small & the drying process is
much too prolonged.
Now my improvements consist in using the hydrate of barium, or the hydrate
of strontium in solution with water, two alkalis which make a much stronger
solution than hydrate of lime in clear solution, thus requiring much less water
to be used & the fuel is consequently dried much quicker & the commercial
results more simply obtained, & the density & petrification
hydrate of lime.

Improvements relating to the Treatment of Peat.
I, EDOUARD RISCHGITZ, of Cambridge Lodge Studios, Linden Gardens, Lon-
don, W., Artist Painter, 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 process for the treatment of peat I make use of a solution of hydrate of
strontium, or hydrate of barium, separately or in combination mixed with freshly
extracted peat, after or during the process of disintegration. By preference I
only use enough of the solution, or solutions to bring the disintegrated peat
into a semi-plastic condition so as to facilitate its removal for drying purposes,
either naturally or artificially. Where the peat has more than the ordinary
proportion of impurities I may use a clear solution of carbonate of calcium &
carbonic acid & water.
In countries where there is enough heat to induce rapid evaporation or by
artificial means, I sometimes use a strong solution of hydrate of calcium &
saccharine & water enabling a thicker mixture to be made. The proportions of
the solutions to be mixed with the peat varies according to the quality of the
Price Sd1

page_text: peat from an ounce per pound of peat to 5-10 times or even more than
that quantity depending on the climatic & local conditions.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The mixing of 4 solution of hydrate of strontium or of hydrate of barium,
either separately, or in combination, mixed with disintegrated peat.
2. For inferior peats requiring greater binding of the particles, using a clear
solution of carbonate of calcium, & carbonic acid & water.
3. In some cases to facilitate the binding of the particles using hydrate of
calcium mixed with saccharine & water.
4. In some cases for the convenience of freely distributing the peat in a liquid
state over the drying ground, mixing with the solution of hydrate of strontium,
a clear solution of hydrate of calcium in any quantity required.
Dated this 24th day of February 1899.
