Abstract: The present invention relates to an alternating seam for joining two pieces of stretchable fabric. The alternating seam can be used for making garments, such as pant garments. The alternating seam has a non-inverted seam that extends from a seam inversion point to a desired length below the seam inversion point. Outer sides of the two fabric pieces are in opposing contact with each other along the non-inverted seam. The alternating seam also includes an inverted seam that extends upwardly from the seam inversion point. Inner sides of the two fabric pieces are in opposing contact with each other along the inverted seam. The alternating seam includes an overlapping seam, which may be an extension of the non-inverted seam, extending upwardly from the seam inversion point and curving outwardly to the inverted seam. A pant garment using the alternating seam can be made without any fasteners or elastic.

Abstract: An aquarium includes a water tank received in a picture-frame-shaped housing suitable for either mounting on a wall or being supported on a stand. The housing includes a hidden storage space for neatly storing an air pump. A vertical sheet or partition extending between the sides of the tank divides the tank into a full-width, but relatively thin and flat, bubble conduit behind the partition for carrying air bubbles, and a habitation compartment in from of it for keeping fish. The lower edge of the partition is spaced above the bottom of the tank to form a gap or water intake, and the upper edge of the partition is spaced below the water line to form a water return. An elongated air diffuser substantially extends between the side edges of the bubble conduit near its bottom. When supplied air by the pump, the diffuser emits a wide sheet of air bubbles that rise upwardly through the bubble conduit to aerate the water.
