  • Patent number: 4232784
    Abstract: A stand for instruments of metal for use in the field of medicine, particularly odontology, comprising a body composed of a large number of sheets of a liquid impregnatable paper material. The sheets are arranged vertically close together so that the instruments are insertable by their operating ends between the sheets to be retained there during the sterilizing process and are thus stored easily accessible for subsequent clinical work. The sheets of paper are impregnated with a corrosion inhibitor to protect the instruments at least during a sterilizing process.

  • Patent number: 4145393
    Abstract: Gray cast iron can be protected against corrosion in boiling concentrated sulfuric acid if the acid contains precious metals such as gold or the metals of the platinum group. It is possible to add small amounts of compounds of the precious metal to the acid or to bring both the gray cast iron and the acid into contact with metal sheets or wires of the precious metal. It is also possible to use small amounts of the precious metal as an alloying element of the gray cast iron.
