Abstract: A cabin exhaust device for ventilating a vehicle, the cabin exhaust device comprising a vehicle cabin ventilating panel including an inner surface, an outer surface, a top side mountable to a window frame of the vehicle, a bottom side, and one of a first portion and both the first portion and a second portion. At least one aperture is disposed in one of the first portion and the second portion, facing outwardly away from the outer surface. The at least one aperture extends from the outer surface to the inner surface. At least a first air dam is disposed along the vehicle cabin ventilating panel adjacent to one of the first and the second portion.

Abstract: The cabin exhaust device ventilates vehicles provided with retractable windows and mounts on a portion of the vehicle, preferably on a door frame or in an opening between a window panel and a window frame. The cabin exhaust device comprises a squeegee and a ventilation panel having an air dam, a first portion, and a second portion, wherein the first and second portions are provided with angularly oriented apertures, thereby creating a vacuum on the vehicle's interior side. The first and second portions are outwardly convexed, thereby facilitating the creation of a pressure differential between the vehicle's interior and its exterior, thus forcing the air and other contaminants out from the vehicle's interior.

Abstract: Novel gas-permeable membranes which are particularly useful in the packaging of fresh cut fruit and vegetables, and other respiring biological materials. The membranes have an O2 permeability of at least 775,000 ml/m2.atm.24 hrs, a P10 ratio of at least 1.3, and a ratio of CO2 permeability to O2 permeability (R) of at least 1.5, and are made by forming thin polymeric coatings on microporous polymeric films. Preferred coating polymers are side chain crystalline polymers. Preferred microporous films contain inorganic fillers, particularly such films based on ultrahigh molecular weight polyethylene or polypropylene. FIG. 1 illustrates how O2 permeability and R ratio vary for different coating polymers and microporous films.
