Abstract: Besides the individual modules (1', 1'"), a compressed air maintenance device consisting of individual easily interchangeable modules (1), e.g. pressure regulators, oil atomisers (1'"), condensate separators (1'), in which the individual modules (1) may have emitters (8) for the actual operating status and/or predetermined limit values, also has an indicating and monitoring module (1") having optical and/or acoustic signalling devices (10) for the operational and/or fault status determined for the individual modules (1). Said signalling devices (10) can be easily coupled to the relevant emitters (8) of the modules (1). Any necessary maintenance work or operational breakdowns are thus easily recognizable.

Abstract: Disclosed is a duct assembly for conducting compressed air from a fixed component to a component that is movable with respect to the fixed component. The duct assembly contains at least two telescoping, tubular conduit sections with seals between adjacent sections. An upstream transitional joint rotatably interconnects the outermost conduit section with an air supply duct, while a downstream transitional joint rotatably interconnects the innermost conduit section with an air delivery duct. A tubular double-wall spaced apart from the inner surface of the innermost conduit section forms an annular airspace between the tubular double-wall and the innermost conduit section. A second double-wall forms a second annular airspace between its downstream end and the upstream transitional joint. The annular airspaces created by the double-walls protect the seals.

Some benefits of electrical power generation available in more sophisticated system designs are thereby obtained with a smaller, simpler, inexpensive and reliable system.

Abstract: The present invention is directed to a container apparatus and method for packaging contoured articles, particularly contoured articles containing hazardous substances. The container apparatus comprises a base member, upstanding sidewall members foldably emanating from the edges of the base member, and an article retaining member foldably emanating from the top edge of at least one of the sidewall members. The article retaining member is positionable toward and into the inner region of the container so as to form an acute angle with the sidewall from which it emanates. The article retaining member further includes an article retention edge to engage, stabilize, and prevent undesired movement of the contoured article(s) housed within the interior region of the container apparatus. In particular, the article retaining member prevents migration of the contoured articles in a vertical plane, in a horizontal plane, and in a rotational direction.
