DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an apparatus for dispersing a dye over securities kept in a closed space, at attempts to break open such a space, e.g. a trunk or a safe-deposit box, and of the kind where a pipe system containing the dye is adapted, at unwarranted attempts at opening, to be activated by a release mechanism to release pressure energy for dispersing the dye over the securities.
Trunks for transportation of bank notes are known, wherein a built-in pipe system with apertures for dispersal of the dye can be activated by a release mechanism connecting a pressure container with propelling charge and dye to the pipe system or releasing the propelling charge in a pressure container for forcing dye from a separate dye container out into the pipe system.
It is the object of the invention to provide an apparatus of the kind in question comprising a pipe system which is simpler and cheaper in construction than those hitherto known and which, besides, is more reliable in operation and easier to renovate.
The apparatus according to the invention is characteristic in that each of the pipes of the pipe system comprises a pressure rail constituting a portion of the wall of an oblong chamber, said wall portion being displaceable at release of pressure energy, and said chamber containing a tubular bag with a dye, the wall of said chamber situated opposite to the pressure rail being perforated by one or more longitudinal slots.
The pipes of the system can be produced in a cheap and easy manner as extruded profiles, and the direct influence exerted on the bags with dye immediately under the slot through which the ejection of dye is to be performed, ensures an effective ejection from the entire system without any risk of clogging up or weaker ejection in certain parts of the system because of pressure drop in a pipe system. Besides, the pipe system is easy to clean and renovate by insertion of new bags with dye.
By arranging, according to the invention, knife members at the slot in the chamber containing the bag with dye, it is ensured that the bag will burst only immediately opposite to the slot, which permits a correct control of the dye jets.
By the embodiment described in claim 3 a practically simultaneous ejection from the entire system, a first strong pressure generation in the space between the supporting walls for cutting the bag open, and a subsequent uniform distribution of the pressure in the larger space under the T-rail involving a quiet and uniform compression of the bag with dye, are obtained. The rupture indications under the explosive charge ensure a controllable location of rupture and a practically simultaneous explosion all over the bottom of the body containing the explosive material.
A further security that the bag is simultaneously compressed all over is obtained by using a pivotally hinged pressure rail as described in claim 4. In this case as well, a two-stage explosion may be obtained by constructing the apparatus as described in claim 5, which involves a first strong pressure generation making the rupture indications in the wall of the chamber containing the explosive charge burst and causing the dye bag to be cut open along the slot, and a subsequent pressure distribution blowing the entire pipe system clean of dye at uniform compression.
By the subject matter of claim 6 it is obtained that the pressure rail keeps the bag in compressed condition so that reflux of the dye fluid is prevented, and by the embodiment according to claim 7 it is secured that the bag remains in the chamber during the explosion and the subsequent compression.
A safe control of the dye jets so as to be directed to stacked bank notes, securities, coins or other articles of value is obtained by arranging the pipe system in a tray as described in claim 8.
To prevent an unintended outflow of dye at leakage of the bag, the slot may be covered, as referred to in claim 9, by a penetrable seal.
As stated in claim 10, the pipe system may be built of several independent units, thereby obtaining a further security that th
