Abstract: An appliance having a storage tank disposed on its back surface wherein the storage tank comprises a front cover and a back cover that matingly engages the front cover to form a liquid tight seal with the front cover. The storage tank further includes a phase-changing material disposed within the storage tank and a heat exchanger containing refrigerant tubing which transfers cooling from refrigerant tubing to the phase-changing solution. The storage tank, when fully charged with cooling capacity, maintains the food storage compartment at a temperature of 45° F. or less for at least 8 hours without activating a compressor.

Abstract: A subsea valve actuator apparatus is disclosed for actuating a subsea valve. The valve actuator apparatus includes a housing which defines an enclosure and a rim. A cover cooperates with the rim for sealing the enclosure. A gearbox is disposed within the enclosure the gearbox including a worm wheel which is connected to the subsea valve for actuating the valve. The gearbox includes a seal which is disposed between the worm wheel and the housing for sealing the worm wheel relative to the housing so that lubricant disposed within the enclosure for lubricating the gearbox is sealed within the enclosure. A pressure compensator is disposed within the enclosure for maintaining pressure of the lubricant disposed within the enclosure at substantially the same pressure as the pressure of seawater outside the gearbox.
