COMPLETE SPECIFICATION.
Improvements in or relating to Disinfecting Apparatus.
I, WILHELM LOEBINGER, of 15, Claudinstrasse, N.W., Berlin, in the Empire of
Germany, Merchant, 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;-
-
This invention relates to improvements in disinfecting apparatus of the character
described in the Specification of British Patent No. 8020 of 1898 in which the vessel b
serves for the reception of one or more porous plates impregnated with a solution of
formaldehyde. The inventor has discovered by experiments that the apparatus
serves the purpose quite as well if the solution of formaldehyde is introduced
directly into the vessel 6 (Fig. 1), the use of porous plates p not being necessary.
In this case owing to the heat applied formaldehyde vapours are generated in
the same manner as with the apparatus described. The steam passes through
the pipe d into chamber b where it mixes with the formaldehyde vapours, generated
from the solution, and escapes through the pipe e, being the heating device.
し
Another modification, of the apparatus described in that specification, consists
in the formaldehyde chamber being heated, not from the lower one, that is to
say indirectly, but directly, in which case it is advisable to arrange the two
chambers side by side, instead of one over the other (see Fig. 2). The formalde-
hyde chamber and the water chamber may be also each provided with a separate
supply of heat (see Fig. 3). The condition to be fulfilled is that steam from the
water chamber a should be directed into the formaldehyde chamber b, and escape
from the latter mixed or impregnated with vapours of formaldehyde. When the
formaldehyde chamber is thus directly heated as described, it may either contain
the porous plates p, as in the prior Specification No. 8020 of 1898, or the solu-
tion of formaldehyde as herein before stated. It is also possible to mix or bring
together the formaldehyde vapours and steam, not in the water chamber, but in
a common discharge pipe, h, from which the mixed vapours are led away (see
Fig. 4). The formaldehyde may be also mixed with other liquids, such as for
instance glycerine etc. and then vapourised.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. A modification of the apparatus described in the Specification of Patent
No. 8020 of 1898 for disinfecting purposes by means of formaldehyde, consisting in
the porous plates being suppressed and the solution of formaldehyde introduced
directly into the upper chamber heated from the water chamber substantially as
described.
2. A modification of the apparatus described consisting in the chamber for the
formaldehyde, being heated directly by the source of heat used for the water
chamber or by a separate heater, substantially as described.
