Abstract: A filter including a filter housing having a spillway and a pneumatic intake assembly that draws water from an aquarium into the filter housing. The filter housing being configured to internally mount to the aquarium. The filter housing having first and second chamber oriented in a side-by-side arrangement such that water flows in a generally horizontal direction through a filter cartridge positioned between the first and second chambers.

Abstract: An aquarium filter including a filter housing, a filter cartridge positionable within the filter housing, and a pump assembly. The aquarium filter also includes an indicator arrangement including a first device and a second corresponding device that interconnect to control operation of the pump assembly.

Abstract: An aquarium filter arrangement including a filter housing and a filter cartridge positionable within a filter chamber of the filter housing. The filter arrangement includes a hinged cover connected to the filter housing. The hinged cover is designed to collect condensation when the cover is in an open position, and empty the collected condensation into the filter chamber when the cover is closed. The filtering housing also includes guides located above the filter chamber. The filter cartridge can be positioned within the guides during maintenance of the aquarium.

Abstract: A decorative aquarium arrangement including a decorative structure for use in concealing a filter assembly and a heater. The decorative structure including an inlet and an outlet. The inlet and the outlet are relatively located to create a diagonal circulation of aquarium water within an aquarium to reduce stagnant regions within the aquarium. The heater is further positioned in relation to the filter assembly such that heated, filtered water is dispensed by the decorative aquarium arrangement.

Abstract: A decorative aquarium arrangement including a decorative structure for use in concealing a filter assembly and a heater. The decorative structure including an inlet and an outlet. The inlet and the outlet being relatively located to generate a side-to-side flow component that creates a diagonal circulation of aquarium water within an aquarium to reduce stagnant regions within the aquarium. The heater is further positioned in close proximity to the filter assembly such that heated, filtered water is dispensed by the decorative aquarium arrangement.

Abstract: A shoe sole unit having a polymeric tread including a plurality of lateral structures extending along the midportion of the sole unit and seated in the interior of the tread. The shoe sole unit also has two longitudinal structures to link the lateral structures as well as a heel cradle.

Abstract: An electrical appliance, such as a pressing iron (10), includes a user proximity sensor for removing electrical power from the appliance after a period of non-use. When a user's hand is in close proximity to, or is in a grasping relationship with, a handle (28) of the pressing iron, an antenna (44) that is disposed within the handle is capacitively coupled to the user through a dielectric material that forms the handle wall. When so coupled to the user, a displacement current having a frequency equal to the AC line electrical power frequency signal (50 Hz or 60 Hz) is capacitively coupled between the user's body and the antenna. The displacement current is detected and amplified by circuitry (60) that is connected to the antenna by a conductor (46). This circuitry outputs a signal that indicates the proximity of the user to the handle of the pressing iron. The output signal is in turn employed to disable the operation of a time-out circuit (70).
