Abstract
Abstract The present invention relates to a system for the vehicular transportation of a lock-equipped cassette (1) for valuable documents between a first station, e.g. a bank or a post office, to a second station. The cassette (1) is intended to be kept in a cassette holder or rack (2) in the first station and the second station, and also in the transporting vehicle. The cassette is provided with an electronic circuit (R1,22) which is characteristic to the cassette concerned and which is arranged to co-act with a controlling activating circuit (M1). When the cassette (1) is lifted from its cassette holder or rack a clock circuit located in the cassette is activated and, unless the cassette is replaced in a cassette holder within a predetermined time, causes an alarm to be activated, this alarm being an acoustic alarm, a device for generating smoke within the cassette, releasing a dye onto the valuable documents contained in the cassette, etc.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
167 words
A system for transporting a cassette (1) equipped with a lock and containing valuable documents between a first station and a second station by vehicle, characterized in that the cassette (1) is provided with an electronic circuit which is characteristic to the particular cassette in question; in that the first station, the second station and the transporting vehicle are each provided with a cassette holder or rack (2) which incorporates activating means (M1-M13) which control the electronic circuit (22) and an alarm circuit (A) incorporated in the cassette, the arrangement being such that said alarm circuit is activated when the activating means fail to activate the electronic circuit within a given time interval which exceeds a time interval determined by a timing device (C) incorporated in the electronic circuit, said timing device (C) being arranged to start a count when the cassette (1) is removed from its holder and to produce a control signal for activation of the alarm circuit (A) upon termination of said time interval.
Claim 2
Independent Claim
167 words
A system for transporting a cassette (1) equipped with a lock and containing valuable documents between a first station and a second station by vehicle, characterized in that the cassette (1) is provided with an electronic circuit which is characteristic to the particular cassette in question; in that the first station, the second station and the transporting vehicle are each provided with a cassette holder or rack (2) which incorporates activating means (M1-M13) which control the electronic circuit (22) and an alarm circuit (A) incorporated in the cassette, the arrangement being such that said alarm circuit is activated when the activating means fail to activate the electronic circuit within a given time interval which exceeds a time interval determined by a timing device (C) incorporated in the electronic circuit, said timing device (C) being arranged to start a count when the cassette (1) is removed from its holder and to produce a control signal for activation of the alarm circuit (A) upon termination of said time interval.
Claim 3
Dependent Claim
108 words
A system according to claim 1, characterized in that in addition to the aforesaid activating means the cassette holder or rack (2) in said vehicle also incorporates an activating device (M10) which is characteristic to the vehicle concerned and which co-acts with an electronic identification circuit (R10) in the cassette (1) and with a switch means (31) controlled by the cassette lock (15,16,10,11), the arrangement being such that in the event of the cassette's (1) being unlocked in the vehicle said switch (31) is activated to close an electric circuit, via the electronic identification circuit (R10), to produce said control signal for activation of the alarm circuit (A).
Claim 4
Dependent Claim
85 words
A system according to claim 2, characterized in that the electronic circuit of the cassette (1) incorporates a plurality of magnetically actuatable reed relays (R1-R13) which individually (R4) or in a number of mutual combinations (R1, R2) form said electronic circuit characteristic to the cassette concerned or said electronic identification circuit (R10); and in that the cassette holder (2) is provided with permanent magnets (M1-M13) in positions corresponding to the characteristic electronic circuit or circuits, or the reed relays incorporated in the electronic identification circuit.
Claim 5
Dependent Claim
84 words
A system according to claim 1, characterized in that the electronic circuit of the cassette (1) incorporates a plurality of magnetically actuable reed relays (R1-R13) which individually (R4) or in a number of mutual combinations (R1,R2) form said electronic circuit characteristic to the cassette concerned or said electronic identification circuit (R10); and in that the cassette holder (2) is provided with permanent magnets (M1-M13) in positions corresponding to the characteristic electronic circuit or circuits, or the reed relays incorporated in the electronic identification circuit.
Claim 6
Dependent Claim
61 words
A system according to claim 4, characterized in that those reed relays included in the aforesaid plurality of reed relays but not forming part of the characteristic electronic circuit or the electronic identification circuit are arranged, when influenced by means of a magnet, to close an electric circuit so as to produce said control signal for activating the alarm circuit (A).
