Abstract: The present invention relates to the use of a pop top mechanism of a disposable beverage container which includes a lance in the pop top lever which can be pressed downwardly to penetrate the top of the container allowing a refrigerant inside the container to be released into the atmosphere thereby cooling the contents of the container by evaporation of the refrigerant coolant.

Abstract: A rigid assemblage of a plurality of elongated parallel building construction components adapted to function as an ocean cargo unit, the assemblage including four parallel vertical load bearing beams having at each end of each beam a fitting with a plurality of lifting eyes with all of the fittings and the beams forming three pairs of parallel planes which enclose a right prismatic space wherein all of the elongated members, are held rigidly in parallel arrangement when the assemblage is suspended by a lifting force, applied simultaneously to all beams.

Abstract: A housing unit with wooden framing having a vertical rigid load supporting beam attached to the housing unit at each vertical corner thereof, and having legs telescopically extendable at each end of the beam with a fitting at the outer end of each leg, each fitting having a plurality of eyes to facilitate attachment to a lifting cable. The upper legs and fittings attached thereto may be removed and reattached spacedly downwardly along the unit, front and back, to provide additional foundation support. All the legs extending downwardly may be vertically adjusted so that the unit may be horizontally level on, for example, uneven ground.

Abstract: A housing unit built with load bearing structures (12) at the two ends thereof and including lifting eyes (26) at the corners of the unit such that units can be stacked vertically on each other for transportation.

Abstract: This invention relates to a method of forming a fire resistant seal from a tubular ring of elastomeric material having a garter spring movably mounted in the bore of the seal.

Abstract: The shroud is formed from sheet material and is cylindrical in shape. A plurality of spacers are associated with the sheet material. These spacers are designed to engage the outer surface of a duct to hold the cylindrical sheet material in radially outwardly-spaced relationship to the duct, defining thereby an insulating air gap between the outer surface of the duct and the shroud. The angular space between the spacers serves as gas channels to permit gas to flow between the shroud and the outer surface of the duct, along the length of the duct. The shroud has a straight axially-extending slot along its entire length for easy removal from a duct. An axially-extending edge receiving pocket is formed on the shroud adjacent to the slot for receiving the adjacent longitudinally extending edge of the slot to hold the shroud in a cylindrical shape and to provide a gas tight closure for the slot.
