Manufactured niddy-noddies can be made of different sizes, producing skeins from 12 inches in length to 4 feet in length. The most common size, however, produces a two-yard skein. [3] Very small niddy-noddies are generally used for small samples. Many spinners will spin a sample length of yarn, ply it, and skein it using a niddy-noddy before ...

Each of the handwheels on this CNC control actuates a manual pulse generator. One moves the cross-slide (X-axis) and the other moves the Z-axis A manual pulse generator ( MPG ) is a device for generating electrical pulses (short bursts of low current ) in electronic systems under the control of a human operator (manually), as opposed to the ...

Van de Graaff generator diagram. A simple Van de Graaff generator consists of a belt of rubber (or a similar flexible dielectric material) moving over two rollers of differing material, one of which is surrounded by a hollow metal sphere. A comb-shaped metal electrode with sharp points (2 and 7 in the diagram), is positioned near each roller ...
The 0-6-6-0 wheel arrangement was also used to a limited extent on logging railroads and in mountain terminals. The Western Maryland Railway had a small fleet of 2-6-6-2 locomotives which, at one time, were the heaviest locomotives in the world, weighing 264 short tons (236 long tons; 239 t). They were all converted to 0-6-6-0 locomotives for ...
Noddy (O.F. naudin [1]) also noddie, nodde or knave noddy, is a 16th-century English card game, ancestor of cribbage. It is the oldest identifiable card game with this gaming structure and thus probably also ancestral to the more-complicated 17th-century game of costly colours .
Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven.
