Abstract: An appliance for electrically heated disinfection of contact lenses or similar ojects is provided with a molded plastic housing having a recessed cavity for insertion of a conventional side-by-side horizontal lens storage case containing the lenses immersed in disinfecting liquid, typically saline solution. The cavity has horizontally aligned opposite end openings through the sides of the housing and the openings are located and dimensioned to allow unobstructed sliding passage of the lens case from the cavity so that the lens case will fall by gravitation from the cavity through one of the openings when the housing is rotated 90.degree. to vertically align the openings. The cavity openings thus ensure that the lens case cannot be heated in the appliance in a vertical orientation which could damage the lenses by heated exposure above the level of the disinfecting liquid.

Abstract: A method is disclosed to provide a substantial reduction of marine corrosion in sea water by micro and macro biofouling. An alternating current is generated of a strength and frequency sufficient to shock marine biofouling organisms and sufficient to upset the normal behavior patterns of the marine biofouling organisms entrained in the sea water passing around or through the structure. A second combination of alternating and direct currents are generated between two strategically located electrodes whereby to release into the water around or within the structure controlled amounts of chlorine ions and copper ions to produce an environment actively hostile to potential marine biofouling organisms. The effect of releasing copper ions and chlorine ions simultaneously is that they co-operate in a synergistic manner that greatly enhances the biocidal effect on marine organisms over and above the effect of the separate use of copper ions and chlorine ions.
