    On October 10, 2000, Texaco announced the purchase of General Motors' share in GM Ovonics, [11] [12] [13] and Chevron announced its acquisition of Texaco six days later. [ 14 ] [ 15 ] In 2003, Texaco Ovonics Battery Systems was restructured into Cobasys , a 50/50 joint venture between Chevron and Energy Conversion Devices (ECD) Ovonics .

  3. ECD Corporation - Wikipedia

    en.wikipedia.org/wiki/ECD_Corporation

    ECD Corporation was a small, privately owned [1] American computer and electronics company based in Cambridge, Massachusetts, and active from 1974 to 1983. During its lifespan, the company manufactured a couple pieces of electronic test equipment, the MicroMind microcomputer system, and the Smart ASCII terminal .

  4. Electron capture detector - Wikipedia

    en.wikipedia.org/wiki/Electron_capture_detector

    Depending on the analyte, an ECD can be 10-1000 times more sensitive than a flame ionization detector (FID), and one million times more sensitive than a thermal conductivity detector (TCD). An ECD has a limited [ clarification needed ] dynamic range and finds its greatest application in analysis of halogenated compounds. [ 9 ]

  5. Electrical insulation paper - Wikipedia

    en.wikipedia.org/wiki/Electrical_insulation_paper

    The telephone cables have a large number of conductors that are individually insulated. The paper needs to be thin (30-40 g/m 2). A normal power cable needs more insulation and therefore paper with higher paper density is used, normally 60-190 g/m 2. The paper needs to be strong, elastic, uniform and free of holes or debris.

  6. Energy Citations Database - Wikipedia

    en.wikipedia.org/wiki/Energy_Citations_Database

    ECD provides free access to over 2.6 million science research citations with continued growth through regular updates. There are over 221,000 electronic documents, primarily from 1943 forward, available via the database. Citations and documents are made publicly available by the Regional Federal Depository Libraries.

  7. Electrochromic device - Wikipedia

    en.wikipedia.org/wiki/Electrochromic_device

    An electrochromic device (ECD) controls optical properties such as optical transmission, absorption, reflectance and/or emittance in a continual but reversible manner on application of voltage (electrochromism). This property enables an ECD to be used for applications like smart glass, electrochromic mirrors, and electrochromic display devices.

  8. Corrugated galvanised iron - Wikipedia

    en.wikipedia.org/wiki/Corrugated_galvanised_iron

    Regular ferrous alloys are the most common due to price and availability. Common sizes of corrugated material can range from a very thin 30 gauge (0.012 inches, 0.3 mm) to a relatively thick 6 gauge (0.1943 inches, 5 mm). Thicker or thinner gauges may also be produced.

  9. Hot-dip galvanization - Wikipedia

    en.wikipedia.org/wiki/Hot-dip_galvanization

    Galvanized fumes are released when the galvanized metal reaches a certain temperature. This temperature varies by the galvanization process used. In long-term, continuous exposure, the recommended maximum temperature for hot-dip galvanized steel is 200 °C (392 °F), according to the American Galvanizers Association.
