Title: Nuclear blast detector
IPC: G01T7/12
Filed: 1963-12-20
Abstract: 1,067,200. Nuclear explosion detection. STANDARD TELEPHONES & CABLES Ltd. Dec.20, 1963 [Jan.2, 1963], No.50402/63. Heading G1A. An arrangement for detecting a nuclear explosion comprises means responsive to a characteristic single cycle of electromagnetic wave which is a phenomenon of such an explosion. A testing device is provided which includes timing means for initiating periodically a test sequence which comprises disconnection of the sensor and the load circuit and injection of a signal which simulates that developed in the sensor by a nuclear explosion. The arrangement preferably includes a duplication of the circuitry tested so that a monitoring watch can be maintained during the period of the test. An infrared sensor comprises a photo-cell, enclosed within a hexagonal parallelepiped of filter glass transparent to an optical bandwidth of 7000-9000 Angstroms mounted on an aluminium base, and surrounded by a transparent housing which screws into the base. An incandescent lamp is included within the filter to provide a dummy testing signal. The sensor output is applied to a low-pass filter which rejects signals developed by lightning and thence via a condenser, which rejects slow changes such as from sunlight, to a Schmidt trigger which responds to the fast rise time pulse of the first energy peak, and relaxes on its termination. A slow trigger circuit is connected in parallel with the fast circuit at the filter circuit and includes an 'and' and an 'or' gate. The two trigger circuits control respective ones of a pair of relays through a flip-flop circuit, and thus a shelter door closing mechanism. The channel to be tested is selected by a switch, and the testing is controlled by cams operating micro-switches or by a manual push button. The arrangement, Fig. 10 (not shown) for detecting the cycle of electromagnetic wave includes a hardened antennae of wrought steel in a concrete pedestal and comprises a filter capable of accepting the characteristic signal, Fig. 11 (not shown). The negative and positive half cycles produce respectively a negative pulse, and a positive pulse followed by a negative pulse, the three appearing' in sequence at point P(1) and being applied to a logic circuit arrangement (265) including a Schmidt trigger (264), Fig. 12 (not shown) feeding an and gate (269) and a 200 us one-shot multivibrator (268) the latter being triggered by the trailing edge of the first negative half cycle, and the gate providing an output when a second negative halfcycle is received while the multivibrator is triggered. Automatic testing is initiated by the closing of motorized contacts (284) and duplicate equipment is provided to maintain the watch during testing. The simulated signal for testing is provided by a monocycle oscillator (293).
