  • Matrix addressable electrochromic devices
    Patent number: 4416516
    Abstract: Electrochromic devices utilizing an electrochromic iridium oxide electrode and a tantalum oxide counterelectrode exhibit a voltage threshold and short circuit memory. The short circuit memory and voltage threshold allow the use of these devices in matrix addressing schemes.
    Type: Grant
    Filed: April 14, 1981
    Date of Patent: November 22, 1983
    Assignee: Bell Telephone Laboratories, Incorporated
    Inventors: Gerardo Beni, Lawrence M. Schiavone
  • Iridium oxide based electrochromic devices
    Patent number: 4258984
    Abstract: Electrochromic devices based on electrochromic iridium oxide electrodes are disclosed. These electrodes are iridium oxide entities produced by vacuum deposition techniques such as by sputtering from an iridium target in the presence of an oxygen atmosphere. All solid state electrochromic devices utilizing such electrodes are possible.

  • Electrolytic process useful for the electrolysis of water
    Patent number: 4257856
    Abstract: It is possible to significantly increase the efficiency of the electrolysis of water into hydrogen and oxygen while maintaining stability of the anode. This efficiency increase is obtained by using an iridium oxide anode which is produced by vacuum deposition techniques.

  • Electroless plating of polyvinylidene fluoride
    Patent number: 4180602
    Abstract: A method for electroless plating relatively inert plastics, e.g., polyvinylidene fluoride, with metal, such as gold, copper or nickel has been developed. The process requires that the plastic be treated with a solvent such as n,n-dimethylformamide or dimethylsulfoxide. The plastic is then sensitized with silver followed by treatment with a suitable activator for the electroless plated solution. Continuous adherent thin films of the desired metal coating are produced.
