Abstract: An apparatus and a method for forming reclosable storage containers are provided to form and seal pouches containing products such as consumer food products. The film material handled thereby and the pouches thus formed include an access opening assembly having a reclosable closure assembly that is characterized by mating flexible closure strips having interlocking means that permit the consumer to easily open and readily and positively reclose the formed pouch. The apparatus and method engage together mating strips of film material sheeting to form a substantially closed web of sheet material that is generally spread or flattened and otherwise handled in order to minimize the formation of kinks and the like in seals formed by the apparatus and method.

Abstract: A novel process for the production of substantially amorphous interpolymers of propylene, ethylene and optionally a third alpha-olefin comonomer having between 4 and 8 carbon atoms per molecule is disclosed. The polymers have properties which make them applicable for use, e.g., as hot melt adhesives and as blending components in roofing materials.

Abstract: The present invention provides an unsupported catalyst with superior crush strength for use in a vapor phase reaction for the high yield conversion of lower aliphatic hydrocarbons such as n-butane to corresponding monocarboxylic acids used as acetic acid. The catalyst is prepared by the reduction of a vanadium oxide containing chromium catalyst.

Abstract: The present invention provides a highly efficient process for use in the high pressure catalytic vapor phase reaction for the high yield conversion of lower aliphatic hydrocarbons such as n-butane to corresponding monocarboxylic acids such as acetic acid. The oxidation reaction takes place under hydrocarbon rich conditions. The increased efficiency in this process is realized by the judicious use of steam and the catalyst systems set forth in the instant invention.
