Definitions

• This invention relates to the protection of valuables and more particularly, but not exclusively, to valuables such as banknotes in a cassette of an automatic teller machine (hereinafter "ATM").
• ATM automatic teller machine
• ATM includes an automatic teller machine, a conventional safe, a protected enclosure, a safe, a cashbox, a strongroom, a cubicle or any equivalent device used for the safeguarding of valuables.

• active system i.e. a so-called "active system”.
• pressurised gas into the container to cause it to burst and thereby release its contents, ie. the dye.
• a small explosive charge inside the container could also be ignited. Pressure inside the container builds up rapidly and this causes the container to break. It is important that, when the container breaks, the dye in the container should be dispersed so that effectively each banknote is marked with the dye over a substantial part of the surface area of the banknote.
• An object of the present invention is to address the aforementioned situation.
• the invention provides a protective mechanism for use in an ATM which includes a holder in which a plurality of banknotes are stacked, one against the other, each banknote lying generally in a vertical plane, and a cover which is engageable with the holder and which includes a lower surface which is spaced from and which opposes upper edges of the stacked banknotes, the protective mechanism including a container, a banknote traceability substance inside the container and an explosive device, inside the container, which, in response to a detected signal indicating an attack on the ATM, is ignited and which then causes the container to fracture at a plurality of spaced apart locations or along an elongate path.
• the explosive device includes two or more explosive charges which are positioned spaced apart from each other inside the container and which are, in use, simultaneously initiated.
• the explosive device includes an elongate sleeve or can which may be in the nature of a tube and which contains a charge assembly distributed over at least a substantial part of its length.
• an objective with the explosive device is to ensure that, upon initiation (ignition) thereof, a high pressure is established inside the container at a plurality of spaced-apart locations or along one or more elongate paths so that when the container bursts it fractures essentially over its length or at a plurality of closely spaced locations and not only at a single position.
• the explosive device may extend inside the container from a filling spout.
• the explosive device may be engaged with and be secured to the cover and may be positioned between the lower surface of the cover and upper edges of the banknotes.
• the container is preferably formed, during a plastics moulding process, with one or more rupture lines along which the container is induced to fracture when it is pressurised internally to a suitable level.
• the container may be substantially rectangular with a filling spout close to a corner of the rectangle. Viewed from one side the container may be rectangular but elongate i.e. with a width which is substantially less than the width of the container in plan.
• the filling spout for the container may be adjacent a small dimensioned side of the container.
• the explosive device is preferably positioned extending from the filling spout into the container adjacent the small size side. As noted the explosive device may include an elongate sleeve which contains an explosive charge.

• the mouth of the sleeve is preferably engaged in a sealing manner with an opposing inner surface of a wall of the spout of the container.

• the function of each rupture line is such as to concentrate stresses on the line which cause the material from which the container is moulded to fracture and create a tear which is propagated along the line due to the increase in pressure inside the container.
• the explosive charge also referred to as a pyrotechnic charge
• a pyrotechnic charge is fitted into the sleeve after the container has been filled with the dye.
• the pyrotechnic charge will normally not be classified as a Class 1 product in respect of the relevant regulations relating to the storage, transport and use of dangerous goods.

• the container may be of any appropriate type and preferably is of the kind described in the specification of South African patent No.2013/08221 , the content of which is hereby incorporated into this specification.
• the container may be of a so-called "passive" type, ie. the container is designed to fracture under the effect of a Shockwave which is generated by an external attack on a structure (an ATM) in which the holder is positioned.
• the banknote traceability substance may be of any appropriate kind and preferably is liquid and is in the nature of an indelible dye. As the container is positioned between the banknotes and the cover and is above the banknotes a highly effective dispersal of the banknote traceability substance over the length of the container results.

• Figure 1 of the accompanying drawings illustrates an inner surface 10 of a cassette lid 12 which, in use, is positioned over and engaged with a holder 16 which, in use, is stacked with a plurality of bank notes 20 - see Figure 7.
• the containers 22 are positioned side by side and parallel to each other, slightly spaced apart and abutting the surface 10. Located between the containers is a monitoring and triggering system 26.
• Each container 22 is generally of the type described in the specification of South African patent No. 2013/08221 the content of which is hereby incorporated into this specification. Although this is a preferred form of construction for the container 22 it, nonetheless, is exemplary and is non-limiting.
• the container 22 thus has a body 26 which is of the so-called "passive type” i.e. it fractures under the effect of a Shockwave in excess of a predetermined magnitude produced when an explosive attack is launched on a structure (an ATM) inside of which the holder 16 is positioned.
• a passive type i.e. it fractures under the effect of a Shockwave in excess of a predetermined magnitude produced when an explosive attack is launched on a structure (an ATM) inside of which the holder 16 is positioned.
• the container 22 in plan, is generally rectangular and has a fairly large width 28 while, viewed from one side - see Figure 6 - the container is also rectangular but has a height 30 which is the width of a side wall 32. The height 30 is substantially less than the width 26 of the broad side 28.
• the body 26 has various formations 36 which are designed to facilitate mounting of the container inside the cover 12 and a number of surface formations 38 which are provided to ensure that the container fractures as desired under the effect of a Shockwave produced by an explosive attack on an ATM in which the container is located i.e. to ensure that the container functions as a passive device.
• each rupture line 40 is defined by creating, during the moulding of the body 26, a sharp corner 42 which is such that stresses in the material of the body are concentrated on the rupture line when the body is internally pressurized. Provided the pressurization level is sufficiently high the rupture line, which essentially is a point of weakness designed for the purpose, fractures and the fracture is then be propagated with a tearing action along the line due to the internal pressurization level.
• Figure 3 illustrates an upper rupture line 40 and a lower rupture line 42 on one side of the body 26 i.e. essentially at a junction of the small side wall 32 and the large size sides 28. According to requirement additional fracture lines can be provided as necessary on the opposing small size side or even on the large size side 28.
• the body 26 has a filling spout 54 and a cap 56 is engaged with the spout.
• the body is filled with a banknote traceability substance such as a liquid indelible dye 60.
• An elongate sleeve 64 is placed into an interior 56 of the body after the body has been filled with liquid dye 60 - Figure 4.
• the sleeve 64 has a neck 68 which is shaped and sized to fit closely inside the spout 54 and, in this way, the sleeve 64 is held inside the body 26 generally parallel to elongate opposed walls 32 and 32A of the body 26 and abutting or otherwise close to an inner surface 76 of the wall 32.
• FIG. 5 illustrates in cross section the sleeve with the charge assembly 80.
• the charge assembly 80 includes a pyrotechnic charge 82, stemming 84 in the form of fine-grained silica and a glue plug 86.
• a seal 88 is located between the charge 82 and the stemming 84.
• An initiating element 90 is mounted to the seal and extends into the charge 82.
• the initiator 90 is connected via leads 94 which pass through the stemming and the plug to two conductors 96 which project from the neck 68 which defines a shaped mouth 98 of the sleeve.
• the pyrotechnic charge 82 is confined within the sleeve by means of the stemming 84 which also acts as an absorbent of moisture that possibly could adversely affect the performance of the pyrotechnic charge 82.
• the stemming 84 in turn is held in position by means of the glue plug 86.
• the conductors 96 are threaded through a hermetic seal 106 which provides a gas-tight interface between the conductors and a cap 108 which is threadedly engaged with the filling spout after the assembly process has been completed.
• Figure 7 schematically depicts the mounting and triggering system 26, which is electronically based.
• the system 26 is responsive to a range of different types of attack on the structure which houses the holder 16 into which the banknotes 20 are placed.
• the system includes a sensor 130 which is responsive to noise, a sensor 132 which is responsive to vibration, a sensor 134 which is responsive to an elevated temperature, and the like.
• These parameters are given by way of example and are non-limiting.
• the parameter is associated with a particular type of attack on the ATM housing or structure, e.g. an attack based on the use of an angle grinder, an attack based on the use of an oxyacetylene cutting torch or the like.
• the system 26 also includes an energy source 140 in the form of a battery, and a logic unit 142.
• a signal is transmitted to the logic unit 142 which causes the battery 140 to be connected via the conductors 96 to the initiator 90.
• the pyrotechnic charge assembly 82 is then ignited and an explosive force is generated along a length of the container 22.
• the charge 82 is designed to deflagrate at a very high temperature, of the order of 4000° Kelvin, and not to detonate.
• the deflagration process almost instantly causes the charge 82 to decompose and produce a secondary gas-generating mixture that builds up pressure through confinement.
• the sleeve 64 is fractured by the gas which releases kinetic energy into the dye-filled container 22. A rapid pressure rise inside the container causes the container 22 to fracture.
• liquid dye is essentially incompressible and that the pressurization effect produced inside the sleeve is effectively transferred to the interior of the container which is completely filled with the dye i.e. there is no volume inside the container which does not contain the liquid dye.
• the body 26 is thereby ruptured effectively along all or a major part of the length of the wall 32 and the indelible dye 40 is automatically released, moving under a force generated by the shock of the exploding charge assembly and by gravity action, onto the upper edges of the banknotes 20 inside the holder 16.
• the elongate sleeve 64 is preferred. It is possible for the sleeve to extend along the full interior of the body 26 although generally it has been found that an adequate dispersal of dye results if the sleeve has a length which is at least half the length of the body.
• FIG. 8 depicts four spaced discrete charges 190, 192, 194 and 196 which are mounted to an appropriate carrier 198 and which are interconnected by means of leads 200 which extend to conductors 202 which are similar to the conductors 96.
• the charges 190 to 196 are simultaneously initiated and in a manner similar to that which has been described the body 26 of the (container) is burst open at a plurality of locations along its length, an action which is enhanced by the inclusion of rupture lines in the body.
• the manner in which this occurs is such as to ensure that the body effectively splits along its length and the dye inside the container is thus forced into staining contact with the stacked banknotes 20 below the container.
• the explosive substance or charge may be ignited or detonated and the indelible fluid container ruptures without breaking the lid of the cartridge and preferably also not without breaking the seals the charge to the container.
• the system may be used with an active system or with the passive system. In other words, in case of an explosive attack even if a signal to ignite or detonated the charge fails, the indelible fluid container or rupture as a result of the Shockwave created by explosive attack.
