A vent balloon for use over an air vent including an inflatable body operatively attached to a base on a proximal side, and a removable adhesive attached to a distal side of the base for attaching to an air vent. A method of using a vent balloon by removably adhering an inflatable body of the vent balloon through a base to an air vent, flowing air through the inflatable body, and inflating the inflatable body. A vent balloon for dispersing scent in a room, including an inflatable body operatively attached to a base on a proximal side, a removable adhesive attached to a distal side of the base for attaching to an air vent, and at least one scent mechanism operatively attached to the vent balloon for dispersing scent in the room. A method of dispersing scent in a room using the vent balloon.

Vent balloon

A vent balloon, including an inflatable body operatively attached to a molded plastic base on a proximal side, wherein the inflatable body is inflated by a mechanism of an air vent or a fan operatively attached to the molded plastic base, and including a scent mechanism operatively attached to the molded plastic base for dispersing scent in a room that relates to a design on the inflatable body. A method of using a vent balloon by flowing air through an inflatable body of a vent balloon through a molded plastic base, wherein the air comes from a source of an air vent or a fan operatively attached to the molded plastic base, inflating the inflatable body, and flowing air over at least one scent mechanism operatively attached to the molded plastic base that relates to a design on the inflatable body and releasing scent into the air.

A process of mechanical hydroforming, in which a hollow tube is caused to expand against the interior surface of a die that surrounds the tube by hydraulic pressure applied to a liquid that fills the interior of the tube, is improved by coating the part of the exterior surface of the tube that comes into contact with the die surface against which it expands with a wax that is solid at normal room temperature but can be maintained fully melted and in contact with air, without showing any visible evidence of decomposition, at a temperature that is at least 75 degrees C. Preferably, the wax is applied to the surface to be hydroformed by spraying from melt onto the surface while the latter is maintained above the melt temperature of the wax. Shortly after the wax has been thus applied to the surface, the wax is cooled until it solidifies. Most preferably, the wax is an &ldquo;oxidized hydrocarbon&rdquo; wax that is about 95% hydrocarbon and 5% straight chain carboxylic acids and contains a wide variety of molecular weights of both hydrocarbons and carboxylic acids.
