Abstract
1,161,604. Selective perforating. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 28 July, 1966 [13 July, 1965], No. 33962/66. Heading B4B. [Also in Division B6] An electrode assembly for generating pressure waves in sequentially operated perforating devices comprises a series of closely adjacent spark gaps in which all the spark gaps are electrically connected in parallel and have a common discharge circuit, and including sequentially operable ignition electrodes 31- 40 (not all shown) for the individual spark gaps which are electrically isolated and spacially separated from each other. The ignition electrodes, e.g. 36, Fig. 4, are fitted between insulators 65, 66 and the tip is flush in a chamber FK. Common main electrodes 1, 2, are rod shaped and fitted into copper blocks 61, 62. The discharge may be along the surface of the insulators or through the air, in which case the electrodes 1, 2 project slightly into the chambers FK. Wear of the insulators may be reduced by using liquid insulation means. In a modification, Fig. 6, the main electrodes 1<SP>1</SP>, 2<SP>1</SP> extend through the blocks 65, 66 and are mounted in the copperblocks 61, 62. Discharge occurs in the direction of the sequence of the separate spark gap. The main electrodes 1 and 2 are connected to a capacitor C, charged immediately after discharge through an inductor L and a diode D to a voltage 2U B and discharges the required energy to cause a pressure wave to effect the perforation. The ignition electrodes 31 &c. are connected to an ignition distributer 2G whose distributing contact 5 is mechanically connected to a scanning device A.
