Abstract
Official abstract text for this publication.
A wireless detonator initiating arrangement ( 10 ) which includes a first housing ( 20 ) which contains a receiver ( 24 ) and a signal processor ( 28 ), a second housing ( 36 ) which contains an explosive ( 38 ), a casing ( 52 ) which contains an initiator ( 16 ) which is responsive to the signal processor ( 28 ) to ignite the explosive ( 38 ) and a third housing ( 46 ) which contains a power source ( 50 ) to power the signal processor ( 28 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A wireless detonator initiating arrangement ( 10 ) which includes a first module ( 12 ) comprising a first housing ( 20 ) which includes contacts ( 58 ) and in which is mounted a signal processing assembly ( 24 , 28 ), a second module ( 14 ) comprising a second housing ( 36 ) which is engageable with the first housing ( 20 ) and which contains an explosive material ( 38 ), and an initiator ( 16 ) which is engageable with at least the first housing ( 20 ) characterised in that the initiator ( 16 ) includes a first end ( 16 A) which is locatable in a first recess ( 30 ) in the first housing ( 20 ) and a second end ( 16 B) which is locatable in a second recess ( 40 ) in the second housing ( 36 ), in that the wireless detonator initiator arrangement ( 10 ) further includes a third housing ( 46 ), with contacts ( 56 ), which contains a power source ( 50 ) and which is engageable with the first housing ( 20 ) whereby the contacts ( 56 ) are connected to the contacts ( 58 ) to enable the power source ( 50 ) to power the signal processing assembly ( 24 , 28 ), and in that the first module ( 12 ) includes a switch ( 54 ) which is actuable manually or electrically to control the connection of the power source ( 50 ) to the signal processing assembly ( 24 , 28 ). 2. A wireless detonator initiating arrangement ( 10 ) according to claim 1 wherein the initiator ( 16 ) is mounted inside a casing ( 52 ). 3. A wireless detonator initiating arrangement ( 10 ) according to claim 1 which includes a capacitor ( 108 ) in at least one of the signal processing assembly ( 24 , 28 ) and the initiator ( 16 ) to enable a firing sequence to be executed independently of the power source once a fire signal has been received by the receiver ( 24 ).
