medicine. he began to design and develop specialized medical electronics and instruments for his use and that of colleagues that were not commercially available. his driving motivation was to invent and improve on lab instruments to make research easier for scientists. one of his first efforts was a cathode

ray recorder—a moving paper camera that recorded images from a cathode ray tube. it was later used in cardiac catheterization labs. by the early s, dr. gilson developed an electroencephalograph (eeg), a device that records the brain's electrical signals for diagnosing epilepsy, strokes, and tumors....

from its ore by reduction with carbon. considerable effort has to be made to separate the lead ore from zinc ores. in recent years, lead has become one of most highly recycled materials in general use. uses of lead over % of all lead produced ends up in lead-acid batteries, with lead metal as the cathode

these are also used for zero emission and hybrid vehicles, back-up power (for example for computers and telephone systems), and energy storage in remote power applications. figure uses of lead. the rest is used in a wide range of applications: radiation screening, either as metal sheet (when using x-ray...

principles of the gauge, the range of pressures it can measure, and its accuracy over the required range. these factors have been determined by experience and there is a vacuum gauge for every pressure range. for low ("rough") vacuum ranges (higher pressures) between atmospheric and torr, bourdon tubes

are all suitable measurement devices. for mid-range vacuum requirements, those in the + torr to - torr range there are several choices including the capacitance manometer, for more accurate measurements, or the thermocouple or pirani type gauges. for high vacuum, from - torr to - torr, either cold cathode...
