  • Patent number: 4121714
    Abstract: A sterilizable package or pouch is made from a plastic member, generally transparent, which is marginally heat sealed around three sides to a paper member so as to leave an opening at one end for inserting the package contents. The paper member has a portion which extends beyond the area to be enclosed by the marginal heat seal when completed. This portion bears indicia, generally printed on the paper, that changes color upon sterilization (either steam or gas sterilization). The indicia bearing portion is adapted to be separated from the package and inserted therein together with the package contents before the marginal heat seal is completed and the package contents are sterilized.

  • Patent number: 4121007
    Abstract: A novel printed circuit board with a circuit of high precision having a polymer coat layer between a base and a dispersion imaging material layer and a pattern circuit on undispersed portions of the dispersion imaging material layer. Such a printed circuit board is prepared by a simplified process which comprises essentially two steps, namely, exposure of the dispersion imaging material through a circuit pattern mask to obtain a pattern circuit of the unexposed portions and conductive metal plating wherein said unexposed portions are selectively deposited with the conductive metal due to the specific effect of provision of the polymer coat layer directly under the dispersion imaging material layer.
