    Abstract: A detector module for use in a gas monitor assembly to measure changes in electron flow resulting from absorption of electrons in an electron capture gas includes an internal housing for containing a radioactive source and electrodes suitably spaced apart to permit gas flow therepast. The internal housing along with couplings for interconnection with a gas flow source, a gas receiver and suitable electronic receiver means are disposed within a detector housing having integrally attachable closure means, the detector housing and closure means providing shielding for the radioactive source while being adapted in combination to prevent operating access to the couplings in order to prevent accidental or undesired exposure of the internal housing and radioactive source.

    Abstract: A reliable delay detonator device is disclosed which is thermally and chemically stable and which is also insensitive to mechanical shock and electrostatic charge. The device can be made with differing time delays and can be interconnected with other detonator devices for achieving multiple delay characteristics. A modification of the device is particularly suited to high temperature use. None of the devices contain any primary explosives, the device relying upon pyrotechnic delay materials and secondary explosives.
