Abstract: A plastic storage and transportation container for loose cartridges, in which container static electricity arising inside the container may be conducted outside the container by a conductive fiber material disposed on the inner surface. The shell of the container is a thermoplastic tube structure. The conductive fiber material is preferably carbon fibers fixed to the inner surface of the tube structure in connection with its preparation. The cover and/or the bottom portion of the container is formed by a plug part made of a conductive plastic.

Abstract: A device for protecting the hearing of a user which includes an ear hood secured to a helmet by a pivotable bow which can be moved forwardly and rearwardly of the helmet and also laterally thereof. The bow is provided with a sliding surface over which a pin slides when the ear hood is moved outwardly. A spring member is connected at one end to the helmet and at the other end to the slidable pin for normally holding the ear hood against the ear. When the ear hood is moved laterally from the ear of the user the pin slides over the sliding surface so that the spring member urges the bow to remain in its outward position.
