geissler tubes tour : click picture below for previous back to mike's electric stuff click picture below for next geissler tubes these intricate glass gas-filled tubes were made in the early s, as a scientific curiosity for use with the induction spark coils which were popular at the time. my tubes below

are all - " long. larger and more intricate tubes were made, in sizes up to ", with the glass tube formed into all sorts of twists, bows and spiral shapes. the inverter modules for cold-cathode flourescent (ccfl) lcd panel backlights work very well for powering geissler tubes, although you shouldn't...

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....

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...

in the uk, copper is mainly used to make semi-finished products (called semis) which are made from the refined metal, either as pure copper or as copper alloys. they can be in the form of wire, rod, bar, plate, sheet, strip, foil or tube. over half the copper is sold in the form of cables, wire and tubes

final purification is by electrolysis (figure ). slabs of impure copper (blister copper), together with thin sheets of pure copper metal or stainless steel or titanium are immersed in a solution of copper(ll) sulfate ( mol dm- ) and sulfuric acid ( mol dm- ). the pure copper or steel sheets make the cathode...
