APPARATUS FOR REDUCING ROTATION OF AN ARTICLE

摘要

An apparatus for reducing rotation of an article such as a bird for holding a superconducting quantum interference device for use in airborne transient electromagnetic mineral prospecting. The apparatus includes a support sphere (20) having an inner shell (23) and an outer shell (21). Liquid is contained between the inner and outer shells (21 and 23) and the sphere (20) has openings (22) through which support strings project for locking to an internal point within the sphere. The strings (24) have one end connected to an internal point within the support sphere (20) and another end connected to a spring (14). T he spring (14) includes a damper (18) for damping movement of the spring (14). Baffles (50) are arranged in the cavity between the inne r and outer shells in which the liquid is contained for damping movement of the liquid.
