I ALEXANDER LOUIS DUSSEK of Verney Road, Canal Bridge, Old Kent Road in.
the County of Surrey 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:--
My invention relates to improvements in the production of antiseptics and
disinfectants. The methods for their preparation are as is hereinafter stated.
I provide as a base any vegetable Tar, such as Stockholm Archangel, or
American Tar, of which substance I place 16 barrels equivalent to about
400 gallons in a copper still, designated for convenience sake No 1. I heat
the mass to boiling point by means of super-heated steam or fire, and I then
distil the acids, spirits, and oils (about 120 gallons) thereof through a suitable.
copper worm or condenser. This portion contains all the extracts of Tar most
suitable for antiseptic and disinfecting purposes. I separate the acids and treat
them as is hereinafter mentioned. The spirits and oils I place in another copper
still (No 2) and I add to them about the same quantity of Turpentine. I bring.
this mixture to boiling point by means of super-heated steam, or ordinary fire, and
then distil about one third, or 40 gallons, thereof through a copper worm or
condenser. The residuum in still No 2, contains the principal extracts of Tar, and
Turpentine. Next, I place in an open copper boiling-pan, designated No 1, two
parts of the prepared fluid (or residuum) from still No 2, and one part of gum-
arabic, or rosin, and I carefully heat them by means of gas until the gum-arabic,
or rosin is dissolved. I then place the solution so prepared in a copper cooling-pan
until said solution is thoroughly cold, after which it is conducted to another copper
boiling-pan, No 2, in which last mentioned pan, a solution of caustic-soda, and
water has been prepared (or alkali without water may be used) and the mixture is
gradually heated until the caustic-soda, or the aforesaid substitute therefor is
dissolved. The solution so obtained is then discharged into a copper cooling-pan
in which it is allowed to remain, so that, the sediment may separate, and the clear
extract be drawn off into clean vessels. This extract is the strong and powerful
antiseptic and disinfectant which I call "Sano,"

page_text: My invention further consists in the production, of a cheaper and less powerful
description of "Sano", which I obtain as follows.
I take the acids, or spirits, or oils hereinbefore respectively mentioned from
still No 1, either separately or mixed, in their crude conditions and in a convenient
proportion. I place them in an open copper-boiling pan, No 1, and add to them
one part of gum-arabic, or rosin. This mixture is carefully heated by means of
gas until the gum-arabic or rosin is dissolved; it is then poured into a copper
cooling-pan in which it is allowed to remain until it is thoroughly cool. It is then
conducted to a copper boiling-pan, No. 2, in which a solution of caustic-soda and
water has been prepared, (or alkali without water may be used) and again
gradually heated until the caustic-soda, or its aforesaid substitute is dissolved.
It is lastly placed in a copper cooling-pan so that, the sediment may separate, and
the clear extract be drawn off into clean vessels.
My invention lastly consists in the production of a disinfecting powder which
I call "Sano," and which is made either with the strong and powerful fluid herein-
before first mentioned, or with the Turpentine, Spirits of Tar, Tar Oils, or acids
hereinbefore mentioned either separately or mixed in about equal proportions, and
the other constituents hereinafter mentioned. I take 5 cwt Burnt Chalk, Grey
Stone Lime, or Barytes either separately, or mixed, or other suitable basis, and
pass the mass through a grinding mill to which are attached two sieves one of
which is above the other. The lower sieve is of a finer mesh than the upper sieve,
and in consequence thereof the chalk, or lime, or Barytes, or the mixture thereof is
reduced to a fine powder. This powder is spread out on a concrete floor in a
powder-shed and saturated with 4 gallons of the strong fluid "Sano" first herein-
before mentioned, or 6 gallons of the weaker fluid "Sano" secondly herein before
mentioned, or a larger quantity according to the strength of the powder required,
and then allowed to dry. The drying process takes a considerable time, during
which the powder is occasionally turned over so that the fluid may be well
incorporated with it. The powder lastly is again subjected to the grinding and
sifting process herein before described after which it is ready for use.
For the production of a superior quality of the powder I use the liquid "Sano
first herein before described, and for a common quality I use the crude Turpentine
or the Tar products hereinbefore mentioned either separately or in combination.
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-
1. The preparation or treatment of the constituents first herein before mentioned
and their employment in a state of combination or mixed substantially as and for
the purposes hereinbefore mentioned.
2. The preparation or treatment of the constituents set forth under the second
head of the foregoing specification and their employment in a state of combination
or mixed substantially as and for the purposes herein before mentioned.
3. The preparation or treatment of the constituents set forth under the third
head of the foregoing specification and their employment in a state of combina-
tion or mixed substantially as and for the purposes herein before mentioned.
