Abstract

Disclosed is an apparatus for destroying the contents of a safe when the safe is moved beyond a certain position. The safe has a device which is supplied with power independently of the mains supply and which detects when safe is moved beyond a particular position. On occurence of such a movement, the contents of the safe are sprayed with a fluid such as ink or with a chemically active compound to either mark or destroy the value documents inside the safe.

Apparatus for Destroying the Contents of a Safe

      Disclosed is an apparatus for destroying the contents of a safe
when the safe is moved beyond a certain position.  The safe has a
device which is supplied with power independently of the mains supply
and which detects when safe is moved beyond a particular position.
On occurence of such a movement, the contents of the safe are sprayed
with a fluid such as ink or with a chemically active compound to
either mark or destroy the value documents inside the safe.

      Fig. 1 shows an overview of the apparatus of this disclosure.
It shows a glass tube 10 which is filled with a gas under pressure
and protrudes into the safe 20.  The fluid container 30 contains the
fluid which is to be sprayed into the safe 20.  Fig. 2 shows a valve
80 positioned at the head of the glass tube 10.  A piston 90 within
the valve 80 is held in position between a spring 50 and a membrane
70.  The membrane 70 is pushed against the piston 90 because of the
higher gas pressure in the glass tube 10.  When, however, the glass
tube 10 is broken, for example because of the movement of the safe 30
by more than a few millimeters, the glass tube 10 is broken and the
gas pressure within it falls.  As a result, the piston 90 is no
longer held in place by the membrane 70 and it is pushed by the force
of the spring 50 in the direction of the glass tube 10 as is
indicated by an arrow in Fig. 2.  An opening 95 within the piston 90
switches the press...
