Abstract: An aircraft engine nacelle nose cowl has a supply duct to deliver pressurised hot gas into an internal compartment of the nose cowl. A slot is provided in the nose cowl to enable pressurised hot gas to pass out of the compartment through the slot. As the pressurised hot gas passes out of the compartment through the slot, this causes a film of water on an outer surface of the nose cowl to detach from the nose cowl. The slot is of restricted dimensions which causes localised heating of the nose cowl around the slot as the pressurised hot gas pass out of the compartment through the slot. In this manner ice is prevented from accumulating on the outer surface of the nose cowl and/or ice is removed from the outer surface of the nose cowl.

Abstract: A heat shrinkable bag having a non-shrink header for containing a product. The bag includes first and second side walls formed from heat shrinkable material joined together to form a body portion having an opening for access into an interior chamber having an inner surface to receive and contain the product. A header is attached to the inner surface of the body portion and extends outwardly from the opening in the body portion. The header is substantially formed from non-shrinkable film material that prevents distortion of the header during manufacture of the bag.
