Appeal No. 1999-2845 Page 7
Application No. 08/495,471
Held's invention relates to receptacles such as tanks,
cans or similar containers for combustible liquids, such as
petrol, benzole, ethylether or the like, having a low boiling
point and forming explosive vapors, and more particularly to
tanks of vehicles, such as motor cars, airplanes and the like
(column 1, lines 1-7). Held's object was to develop a tank
which offers maximum safety against explosions (column 1,
lines 8-11). As shown in Figure 1, Held teaches (column 2,
lines 1-38) the use of a tank 1 having a charging and
discharging opening 2, which may be closed by a lid 3. In the
interior of the tank 1 there is arranged a number of vertical
and horizontal partitions 4 which consist of wire cloth,
perforated sheets, etc., which are well permeable to the
liquid but which have the necessary strength in order to keep
a glass wool filling in proper position and to prevent the
glass wool filling from being upset and sticking together.
The space between the partitions 4 is filled up with loose
glass wool 8 in such a manner that preferably the whole
interior of the tank, except for a small space 9 underneath
the inlet 2 which is provided with a perforated cylindrical
body 10, is filled with glass wool.
