An inflatable cushion bag for striking includes an outer wall and an inner wall that is positioned inside and longitudinally with the outer wall looped around the inner wall. A first radial wall is joined to each of and connects between the outer wall and the inner wall at a first end and is sealed so that free airflow is blocked at the first end. A second radial wall is joined to each of and connects between the outer wall and the inner wall at a second end and is sealed so that free airflow is blocked at the second end. At least one intermediate radial wall is placed longitudinally between the first radial wall and the second radial wall and transversely between the outer wall and the inner wall. The intermediate radial wall may have a small opening such as a hole with a diameter less than ½ inches or an equivalent so that the opening allows a slow airflow through the intermediate radial wall for inflating or deflating the bag and, when inflated, restricts airflow through the opening to give a shock absorber effect to make the outer wall an added cushion when punched or kicked.

An apparatus and method for reducing contamination of an image transfer surface in an image transfer device includes a charging device for charging the image transfer surface. An airflow control system ventilates the charging device and restricts airflow adjacent the image transfer surface.

This application is directed to a fragrance dispenser attachably connected to a fan comprising: a housing having openings defined in the housing; a fragrance reservoir included in the housing for receiving a fragrance medium containing a fragrance; a cover operably associated with the opening for restricting airflow into the fragrance reservoir; and, a cover actuator operably connected to the cover having an open position allowing airflow into and out of the fragrance reservoir for dispensing a fragrance and a closed position for restricting airflow into and out of the fragrance reservoir.

The present invention relates to a secondary air injection system for an internal combustion engine, and an automotive vehicle comprising such a secondary air injection system. The arrangement includes shut-off valve for selectively passing on or restricting airflow form the secondary air injection system. A flexible connector is arranged to receive the airflow and pass it on to at least two reed-type non-return valves arranged to substantially only allow airflow in the downstream direction. At the downstream side of each respective reed-type non-return valve a conduit for communicating any airflow passed there through to an associated exhaust bank of the internal combustion engine.

A portable aeration device includes a housing having an air chamber in communication with an ambient air source, a supply area, a valve restricting airflow between the air chamber and ambient air source, and a valve restricting airflow between the chamber and supply area. The housing defines an exit in communication with the supply area, the aeration device having a cap selectively covering the housing exit. The aeration device includes a diffuser having a plurality of openings, an output tube extending from the diffuser to a location in communication with the supply area to alternately supply air from the supply area to the diffuser and allow liquid to pass from the diffuser to the supply area. A pump is in communication with the air chamber to force air from the air chamber to the supply area. The aeration device includes a fastener for attaching the housing to a water bottle.
