Abstract

1299303 Preventing theft H J ROBESON and J L BIRCHFIELD 15 Feb 1971 4637/71 Heading E2X A robbery protection device for temporarily disabling or marking a robber comprises a dummy packet of currency having concealed within a disabling or marking agent and means for detecting an external electromagnetic field and activating said agent. A transmitter Fig. 6, providing the triggering electromagnetic field, is located in the escape path of the robber. The protection device detects the electromagnetic field through a sensor S', Fig. 5, which sends a signal through an amplifier B and time delay circuit H to an ignition device I which activates the agent, e.g. coloured smoke or tear gas powder.
