Edward Weston (chemist) instruments for electric current—the modern foundation for the voltmeter, ammeter and wattmeter. In 1888 he formed the Weston Electrical Instrument Corporation which would become famous for its voltmeters, ammeters, wattmeters, ohmmeters, frequency meters, transformers, and transducers. Weston developed a method for producing a "true" permanent magnet. Weston conceived of and built a magnetic speedometer. Weston also developed the dashboard ammeter for Harley-Davidson motorcycles. Also in 1888, Weston became president of the American Institute of Electrical Engineers (AIEE) until 1889. Weston invented and patented the saturated cadmium cell in 1893. The cathode in the cell is an amalgam of cadmium with
Special measures the action plan has been completed and all points satisfactorily addressed, then they will refer the school back to Ofsted and ask them to schedule a second Section 5 Inspection. If Ofsted agree with HMI’s judgement, the school is then removed from the special measures category. It is worth noting that during an Inspection an HMI can change the nature of the Inspection to a Section 5, and remove the school from Special Measures upon completion. Support for schools that enter special measures comes in a variety of forms, and varies from local authority to local authority. Typically though schools
