  • Patent number: 6311621
    Abstract: A shock-resistant electronic circuit assembly (10) is provided in which an electronic circuit is encased in an encapsulation (14) that engages a surrounding enclosure (18) in shock-dispersing contact therewith. The encapsulation may have a plurality of edges (16, 16a, 16b), fins (24) or bosses (70) that bear against the enclosure. The encapsulation may include a shock-absorbing material (14f) disposed against the enclosure to protect the circuit against vibrations and a structural support material such as a casing (14e) to protect the circuit against stress. The circuit assembly (10) may be part of a sheathed initiator assembly (55) that includes a transfer member (58) for converting shock wave energy into electrical energy for the electronic circuit, and the released energy may be converted into a detonation initiation signal. Assembly (55) may be part of a detonator (100) that receives a non-electric initiation signal and detonates following the delay determined by the electronic circuit.

  • Patent number: 6125762
    Abstract: A flat-form separation device (12) is made of two half-section members (22, 22') which are fastened together by a series of fasteners (38) to define therebetween a receiving channel within which an expansion device (40) is received. Aside from the receiving channel and any apertures which are to receive mechanical fasteners, the separation device (12) is solid throughout and free of other channels or cavities. The device (12) includes a pair of joinder flanges formed by mating half-flange segments (28a and 28b), which contain apertures (32 and 34) by which the flat-form separation device (12) may be secured to structures (48, 50) which are to be temporarily joined by the device (12). Because of the cross-sectional profile of the half-section members (22, 22'), they may be made by manufacturing techniques, such as machining, which enable the use of alloys or metals which are much tougher and stronger than those which can be extraded to form prior art hollow-form separation devices (14).

The circuit assembly (10) may contain a capacitor (34) for storing an electrical signal and timing circuitry for releasing the stored energy after a predetermined delay. The circuit assembly (10) may be part of a transducer-circuit assembly (55) that includes a transducer module (58) for converting shock wave energy into electrical energy for the electronic circuit, and the released energy may be converted into a detonation initiation signal.

  • Patent number: 6021715
    Abstract: A manifold (130) is configured to have a body portion (131) having at least one initiation port (132) for receiving an initiation device and at least one tapered boss (138) mounted on the body portion (131). The boss (138) has an elliptical cross-sectional configuration and a boss bore (140) for receiving a fuse or linear explosive charge (16) and it communicates with the initiation port (132). There is a clamp member (160) having an aperture (164) dimensioned and configured to generally conform to the boss (138), and tension means such as a set of bolts (166) for urging the clamp member (160) towards the manifold (130). There may be a bushing material (121) on the boss. The manifold (130) may be coupled to a separation device (23) that includes a frangible joint (24) through which is disposed an expansion member (110).
