A medium-fast bowler with one of the better hitting eyes in
the game, Richard Petrie flashed over the cricket horizon in the summer of 1990-91 playing 12 one-day internationals. And from that point until he retired from first-class cricket in 1999-00, that was the only time he played international cricket. A bowler capable of extracting disconcerting lift, Petrie's aspirations were dealt a severe blow when he suffered an Achilles tendon injury. It reduced his speed considerably and he reverted to more guile to secure his wickets. His hitting ability made him an invaluable prospect in one-day cricket, a point utilised by Wellington after his transfer there from Canterbury in 1993-94. While he achieved a first-class century, his highest score in one-day games was 85, but there was no doubtinto a front chamber and a rear chamber, and may include at least one fluid passageway. A portion of the plates is disposed in the front chamber and a portion of the plates is disposed in the rear chamber. The adjuster plate may include a moveable member adapted to adjust the cross-sectional area of fluid passageway and thus the cross-sectional area of fluid communication between the front and rear chambers. The apparatus may include a collector-separator to collect gases from the reaction chamber and separate any remaining water from the gases. The separated water is returned to the reaction chamber, and the hydrogen and oxygen gases are transmitted to a bubbler assembly which functions to prevent any flashback from igniting the gases in the reaction chamber or collector-separator.
