  • Patent number: 6962723
    Abstract: The present invention provides a process for extracting minerals from mineral-rich oysters and furthermore provides an oyster extract containing the minerals, and taurine, glycogen, and nucleotides. First, raw oysters are subjected to hot water extraction to obtain soluble ingredients and to remove unwanted components, and then the residue is extracted with an acid solution of pH 2 to 4. The extract is neutralized with an alkali to obtain a precipitate having a high content of minerals such as zinc. The oyster extract obtained by this process contains zinc in the amount of 6% to 13% by dry weight.

  • Patent number: 4451228
    Abstract: A burner of wick type is disclosed which secures user safety by stopping combustion through an oxygen depletion protection function in the event of an oxygen depletion. When tar is accumulated in the wick, the wick is burnt to clean the tar with the liquid fuel supply cut off, thus burning out the liquid fuel contained in the wick. In the process, the combustion temporarily becomes unstable and a great amount of carbon monoxide is generated, resulting in a state similar to oxygen depletion. In a burner with an oxygen depletion protection function, the combustion is stopped during the wick cleaning, with the result that most of the tar accumulated in the wick remains unburnt, adversely affecting both the fuel absorption characteristic and service life of the wick. This invention is such that the oxygen depletion protection function is not operated during the wick cleaning.
