Abstract: A unique method and apparatus for inserting an oxygen scavenger into a modified atmosphere package for extending the shelf life of food, especially raw meats. A scavenger feeder feeds a chain of interconnected oxygen scavengers. A separator separates the oxygen scavenger located at an exposed end of the chain of interconnected oxygen scavengers from the chain of interconnected oxygen scavengers. An adhesive applicator applies adhesive to the oxygen scavenger which has been separated from the chain of interconnected oxygen scavengers. A conveyor conveys the separated oxygen scavenger to a position which is adjacent to a film layer which is used to form an outer package of the modified atmosphere package so that the oxygen scavenger is attached to a surface of the film layer by the adhesive. The film layer is subsequently formed into the outer package so that the oxygen scavenger that is attached to the film layer is contained within the outer package.

Abstract: Sipping straws are confined in discrete envelopes while advancing in a single file of spaced-apart straws through a wrapping station. The envelopes are obtained from a continuous strip of wrapping paper which is conveyed to the wrapping station in the direction of advancement of the file of spaced-apart straws and is draped around the straws in such a way that one of its longitudinally extending marginal portions overlies and adheres to the other marginal portion with simultaneous formation of a seam rather than an outwardly extending fin. The thus obtained tubular wrapper is thereupon severed in the gaps between successive spaced-apart straws, and the end portions of the thus obtained discrete envelopes are sealed by knurling, e.g., simultaneously with severing of the tubular wrapper.

Abstract: The method relates to a method for packing articles and/or objects. Articles are packed in an elastic packing material (2) and the elastic packing material is stretched during the packing process. To achieve this, the packing material is arranged in a receptacle (1) in which a partial vacuum is produced. The packing material is stretched due to the pressure that the outside air exerts upon it. The item that is to be packed is then placed in or on the packing material. Once the vacuum has been removed, the packing material automatically reverts back to its original position by virtue of its own elasticity and is applied to the packing items. The invention also relates to a device to carry out such a method.

The corona discharge in the generator produces radicals in the diverted exhaust gas, and the exhaust gas containing radicals is then conveyed to the exhaust gas stream at a point upstream of the outlet of the catalytic converter.
