IMPROVEMENTS IN OR RELATING TO RESONANCE REDUCING ARRANGEMENTS

摘要

The invention relates to a resonance reducing arrangement for a device displaceable between two positions. In one described embodiment the device (14) is displaced against the resilience of a spring (11) by causing an electrical device (15) to accelerate the device (14) towards its second position, terminating the force accelerating the device (14) to allow the device to continue to displace towards the second position and then reactivating the electrical device (15) to cause the electrical device (15) to expand to that position at which it holds the device (14) in its second position.
