  • Patent number: 4189131
    Abstract: A paper spring is formed by longitudinally folding a sheet along parallel fold lines to provide a strip and thence transversely folding the strip in a zigzag manner. The resulting paper spring may be contained in a paper housing in the form of an open-sided rectangular band and a series of the resulting paper spring units may be mounted on a cardboard panel to provide a platen. Such springs or units provide a resilient cushion for fragile items shipped in boxes.

  • Patent number: 4079926
    Abstract: An energy absorbing support formed of a composite coil defining a core and a tubular sheath with the sheath being formed of a material having a higher elastic yield strain limit than that of the core. The coil defines a first portion and a second portion with a support of the coil disposed intermediate the first and second portions. Structure is provided for applying a preselected preload to the coil. The coil materials are preselected to maintain elastic and damping characteristics at cryogenic temperatures, such as below -150.degree. F. The support is adapted for use in rigorous environments such as encountered in the space shuttle and the like, and provides lightweight, long life, resilient support of critical elements, such as piping and the like, therein.
