An oscillator that was among the exhibits Tesla demonstrated at the World's Columbian Exposition in 1893. Tesla's electro-mechanical oscillator is a steam-powered electric generator patented by Nikola Tesla in 1893. [1][2] Later in life Tesla claimed one version of the oscillator caused an earthquake in New York City in 1898, gaining it the ...
An oscillating multi-tool or oscillating saw is a multitool and power tool that oscillates (rather than rotating or reciprocating), powered by battery or mains. The name "multi-tool" is a reference to the many functions that this tool can perform with the range of attachments available. "Master Tool" is also a trade name used in North America ...
Steam-powered oscillating generator Main article: Tesla's oscillator During his presentation at the International Electrical Congress in the Columbian Exposition Agriculture Hall, Tesla introduced his steam powered reciprocating electricity generator that he patented that year, something he thought was a better way to generate alternating ...
www.fein.de. C. & E. Fein GmbH is a manufacturer of high-end power tools located near Stuttgart, Germany. Founded in 1867 by brothers Wilhelm Emil Fein and Carl Fein, the company invented the hand-held electric drill in 1895 and was responsible for many other innovations. Fein became famous for its grinders, electric screwdrivers, and Fein ...
A spark gap (SG) that acts as a switch in the primary circuit. The Tesla coil (L1, L2), an air-core double-tuned resonant transformer, which generates the high output voltage. Optionally, a capacitive electrode (top load) (E) in the form of a smooth metal sphere or torus attached to the secondary terminal of the coil.
Oscillation. Repetitive variation of some measure about a central value. An undamped spring–mass system is an oscillatory system. Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states.
Victorinox SwissTool. A multi-tool (or multitool) is a hand tool that combines several individual functions in a single unit. The smallest are credit-card or key sized units designed for carrying in a wallet or on a keyring, but others are designed to be carried in a trouser pocket or belt-mounted pouch. [1]
A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, [1] which is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power ...
