  • Pseudo-thermosetting neutralized chitosan composition forming a hydrogel and a process for producing the same
    Publication number: 20100113618
    Abstract: The composition disclosed is a pseudo-thermosetting neutralized chitosan composition, neutralized with a hydroxylated base, forming a phosphate-free transparent hydrogel at a temperature higher than 5° C. Said composition contains a homogeneously reacetylated chitosan derived from a chitosan having a deacetylation degree of 80-90%, having a molecular weight of not smaller than 200 kDa and a deacetylation degree of 30-60%, and may further contain a diol. Said composition may be used as a drug delivery system.

  • Self-locking hinge for antenna element
    Patent number: 3950758
    Abstract: In an antenna for television, radio or the like, including antenna elements radiating from a boom, a self-locking hinge intermediate the ends of an antenna element for permitting folding of the element for convenient boxing, or the like and for permitting unfolding and elongation of the element for use; the hinge comprising a hinge connection that is spaced from one side of the element and a snap latch that is spaced from the opposite side of the element, thereby rigidifying and strengthening the hinge connection.
