发明名称 Absorbent cartridge for release mechanism powered by contact with fluid
摘要 A water-reacting absorbent cartridge for a release mechanism has multiple layers of water-absorbing paper material compressed into a solid, densified mass with a fraction of the original volume of the paper layers. The compacted cartridge may be wrapped in a tube of heat-shrink material with holes along its sides or may have adhesive interspersed between layers in order to keep the expansible paper layers together. Another water-reacting absorbent cartridge has multiple layers of a super absorbent material interspersed with layers of paper material compressed into a densified mass. The super absorbent material may be a powder dispersed in paper sheets, or in sheet form with paper layers interposed between. The expansible material may be contained in a jacket made of a water-permeable tightly-woven cotton fabric. Further, an oil-reacting absorbent cartridge is made of one or more layers of polyethylene molecular sponge compressed into a "hat shape" with a protruding portion on one side so that it can be seated in an oil detector unit with its expansion force concentrated through its central portion. One or more holes may be punched through the central portion to provide pathways for the oil and speed up the reaction time of the cartridge by a factor of ten.
