Abstract: A dust suction head for use in an electric vacuum cleaner, having an air suction port at the bottom of the head. The head has a brush chamber which accommodates therein a freely rotatable brush having blades that extend along the shaft of the rotational brush. The head additionally has an opening and an air passage connected with the opening for taking in and leading fresh air into the vacuum chamber of the cleaner through the brush chamber such that the fresh air passing through the brush chamber impinges on the blades to accelerate the rotational motion of the blades.     Thus, the head can obtain a necessary amount of air to rotate the brush at all times, especially when it is brushing a carpet, and maintain its smooth motion on the floor while dusting it.

Abstract: A modified atmosphere packaging system and method creates a modified atmosphere in a package including an inner container and an outer container. The inner container is composed at least partially of a polymeric material substantially permeable to oxygen forming a tray, while the outer container is composed of a polymeric material substantially impermeable to oxygen. After a food product such as raw meat is placed within the container, the inner container is flushed with a desired mixture of gases to substantially remove oxygen from the inner container. The flushed inner container is then sealed and inserted into the outer container without sealing the outer container. Next, the outer container is flushed to remove oxygen. After flushing the outer container, the outer container is sealed. An oxygen scavenger is provided in the package to substantially absorb any residual oxygen within the package.
