20080136578 - Method for sheathing a varsitor block with an electrically insulating sheath, as well as a varsitor block for a surge arrester: A method for coating a varistor block with an electrically insulating coating and a varistor block for a surge arrester. A varistor block is formed from several varistor elements. An electrically insulating coating is disposed around the varistor elements. The electrically insulating coating rests directly on a surface of the... Agent: Lerner Greenberg Stemer LLP

20080136579 - High resistivity thin film composition and fabrication method: A thin film composition is made from silicon, an insulator such as alumina or silicon dioxide, and at least one additional material such as chromium, nickel, boron and/or carbon. These materials are combined to provide a thin film having a ρ of at least 0.02 Ω-cm (typically 0.02-1.0 Ω-cm), and... Agent: Koppel, Patrick & Heybl
