Abstract: A valve device (4) for controlling fluid flow comprises a hollow body (2) bounding a flow path through the valve device (4), a valve obturating member (10) in the flow path and movable between a fully obturating position and a less obturating position for permitting lesser and greater flows of fluid along the path, which flows urge the member (10) in the sense from the more obturating position to the less obturating position, the valve obturating member (10) including magnetic portions (18), and at least one electrically energizable inductor (22) fixed relative to the body (2) and serving to act upon the valve obturating member (10) to urge the valve obturating member (10) in the sense from the less obturating position to the fully obturating position.

Abstract: A system for subjecting articles and containers to microbiocidal radiation and for attaching the articles to the containers comprises a source (6) of microbiocidal radiation, a first conveying device (26) for advancing pour spout fitments (21) along a first path, a second conveying device (2) for advancing containers (4) along a second path substantially parallel to the first path, the source (6) being effective along both the first and the second paths, and a fitment applicator (27) arranged to attach to the containers (4) fitments (21) which have been subjected to the radiation.
