Abstract: A substantially W-shaped rack having four legs, each of which is preferably a wire or rod member formed of a single, elongated, bent rod or a plurality of connected rods. It is preferred that each of the legs has substantially the same length. The shape of the rack results in angles being formed between adjacent legs, and it is preferred that these angles do not exceed 45 degrees.

Abstract: An aquarium system comprising a water-tight fish tank and a screening means that divides the fish tank into an upper section and a lower section, one or more barriers that divide the lower section into two or more separate compartments, and two or more outlet orifices are located in the fish tank bottom. A gravel bed is supported on the screening means. A water pump circulates water from each of the outlet orifices, through a water filter, to the upper section of the fish tank. The velocity of the water circulated through the gravel bed by the water pump flushes any waste material from the gravel bed. A flushing velocity may be maintained because the gravel bed covering each separate compartment may be flushed separately.

Abstract: The present invention may be characterized as a rack for holding a container lid so that the lid does not drip sauces and other liquids onto a counter or stove top while cooking. The inventive rack is substantially W-shaped and has four legs, each of which is preferably a wire or rod-like member formed of a single, elongated, bent rod or a plurality of connected rods. It is further preferred that each of the legs has substantially the same length. The shape of the rack results in angles being formed between adjacent legs, and it is preferred that these angles do not exceed 45 degrees.
