  • Patent number: 4790714
    Abstract: A toy in the shape of a collapsible and expandable box is made of cardboard and has a stiff, square top and bottom and four side walls which can be folded to the outside along central folding lines by pressure onto the top. Each side wall is provided with an inwardly extending tongue, and each two tongues on opposite side walls are connected by elastic bands or springs which pull the walls back from their folded position into planar state, as soon as the pressure on the top is released. In this position the toy forms a cube, which may be decorated with pictures, maps, symbols or the like.

  • Patent number: 4374945
    Abstract: Certain substituted thioglycolates and thiopropionates were found useful as secondary stabilizers for polymers, particularly polyvinyl chloride, when used in conjunction with metal octanoates, such as zinc octanoate, as the primary stabilizer. The specific thioglycolates and thiopropionates are those formed by thio adducts to the double bond of a monomer, such as the product of reacting isooctyl thioglycolate with glycidyl acrylate, to provide isooctyl S-2(glycidyloxycarbonyl)ethyl thioglycolate, as an example.

  • Patent number: 4262847
    Abstract: A urethane foam gun is disclosed in which polyisocyanate and polyol feed streams are mixed with air under pressure within the gun with vigorous intermixing in the outlet nozzle to a condition ready for application. Once applied the foam polymerizes in place. The gun is formed with an integral block design in which dual plug valves are mounted for control of the streams. Actuation is achieved by a trigger valve mounted on the gun, and a second gun-mounted valve controls a solvent flush for cleaning to avoid polymerization within the gun itself. The gun is useful for foam-in-place applications, such as protective packaging.
