Abstract
Abstract The safety box or the like, is, in particular, suitable for transportation, has imbedded in its side wall a number of randomly arranged electrically isolated detector loops which, when cut or otherwise destroyed, trip an alarm or trigger destruction of the contents of the safety box. These randomly arranged closed conductor loops can be associated with adjacent conductors, with a voltage being applied between each loop and the adjacent conductor. A timing circuit may be provided to operate, in case of a breaking in of the box, to trip destruction of the box quicker than the box can be broken into. A temperature supervising device is provided to assure a reliable operation of all the detector devices and current sources, and can also respond in case the box is attempted to be cut open by a torch.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
134 words
In a portAble safety box for transporting valuables, of the type including intrusion-resistant closure walls having incorporated therewith externally invisible electric conductor supervisory loops, connected in a closed circuit with a source of potential and an intrusion responsive device, operable, when a conductor is interrupted, to activate the intrusion responsive device, the improvement comprising, in combination, plural irregularly and randomly arranged conductor loops incorporated with each wall of said box and arranged closely adjacent each other, and each forming a closed circuit with a source of potential and said device; whereby said device is activated responsive to interruption of any one of said loops; and means operatively associated with said device and operable, responsive to activation of said device, to at least substantially modify the contents of said safety box in a lasting manner.
Claim 2
Dependent Claim
134 words
In a portAble safety box for transporting valuables, of the type including intrusion-resistant closure walls having incorporated therewith externally invisible electric conductor supervisory loops, connected in a closed circuit with a source of potential and an intrusion responsive device, operable, when a conductor is interrupted, to activate the intrusion responsive device, the improvement comprising, in combination, plural irregularly and randomly arranged conductor loops incorporated with each wall of said box and arranged closely adjacent each other, and each forming a closed circuit with a source of potential and said device; whereby said device is activated responsive to interruption of any one of said loops; and means operatively associated with said device and operable, responsive to activation of said device, to at least substantially modify the contents of said safety box in a lasting manner.
Claim 3
Dependent Claim
60 words
In a portable safety box for transporting valuables, the improvement claimed in claim 1, further including, in incorporation with each wall, plural irregularly and randomly arranged open conductors forming open conductor loops and each arranged closely adjacent a respective closed conductor loop; and a source of electric potential connected to said open loop conductors to apply an electric potential thereto.
Claim 4
Dependent Claim
39 words
In a portable safety box for transporting valuables, the improvement claimed in claim 1, in which said electric conductors are imbedded in a plastic material foil adhered to the inner surface of the associated wall of said safety box.
Claim 5
Dependent Claim
26 words
In a portable safety box for transporting valuables, the improvement claimed in claim 3, in which said electric conductors are evaporated onto said plastic material foil.
Claim 6
Dependent Claim
26 words
In a portable safety box for transporting valuables, the improvement claimed in claim 3, in which said electric conductors are etched onto said plastic material foil.
Claim 7
Dependent Claim
30 words
In a portable safety box for transporting valuables, the improvement claimed in claim 3, in which said electric conductors are imbedded between superposed plastic material foils adhered to each other.
Claim 8
Dependent Claim
67 words
In a portable safety box for transporting valuables, the improvement claimed in claim 6, including a first adhesive adhering the superposed layers of plastic material foil to each other, and a second adhesive adhering said electric conductors to said plastic material foils; said second adhesive being stronger than said first adhesive; whereby, upon tearing of said layers of plastic material foils apart, said conductors will be broken.
Claim 9
Dependent Claim
49 words
In a portable safety box for transporting valuables, the improvement claimed in claim 3, in which said electric conductors are evaporated onto both surfaces of said plastic material foil, whereby variations in the capacity between the two electric conductor layers may be utilized in addition to activate said device.
Claim 10
Dependent Claim
41 words
In a portable safety box for transporting valuables, the improvement claimed in claim 3, wherein said electric conductors are insulated, with the dielectric properties of the insulation of said electric conductors and of said plastic material foils differing from each other.
Claim 11
Dependent Claim
40 words
In a portable safety box for transporting valuables, the improvement claimed in claim 3, wherein said electric conductors are insulated, the temperature properties of the insulation of said electric conductors and of said plastic material foil differing from each other.
Claim 12
Dependent Claim
37 words
In a portable safety box for transporting valuables, the improvement claimed in claim 3, wherein said electric conductors are insulated; the insulation of said electric conductors having the same resistance to acid as said plastic material foil.
Claim 13
Dependent Claim
72 words
In a portable safety box for transporting valuables, the improvement claimed in claim 1, including a timing circuit operatively associated with said device and with said last named means and set to activate said last named means to at least substantially modify the contents of said safety box in a lasting manner, at a rate sufficient to effeCt such modification before an unauthorized intrusion into said safety box can be completely effected.
Claim 14
Dependent Claim
29 words
In a portable safety box for transporting valuables, the improvement claimed in claim 1, in which said last named means effects destruction of the contents of said safety box.
