silver-graphite brushes for tachymetryc dynamos

Commutator (electric)

In the first practical electric generators, called dynamos, the AC was converted into DC with a commutator, a set of rotating switch contacts on the armature shaft. The armature windings conduct AC current even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors. After Jedlik solved the

I decided I would commit to paper, paint, and brushes only and find out how far I could go with this limited arsenal, without getting distracted. In my opinion it is not possible to get whiter than the white of the paper anyway, therefore my particular method of working requires that I preserve areas of white paper to represent any whites that may be in the subject choice.

ELECTRICITY – Dr Rajiv Desai

2012/9/4Silver is the best conductor, but it is expensive. Because gold does not corrode, it is used for high-quality surface-to-surface contacts. However, there are also many non-metallic conductors, including graphite, solutions of salts, and all plasmas.

Dynamo

Dynamos were invented as a replacement for batteries. The commutator is essentially a rotary switch. It consists of a set of contacts mounted on the machine's shaft, combined with graphite-block stationary contacts, called brushes, because the earliest such fixed contacts were metal brushes.

2014/4/6Two inches of No. 36 German silver wire, such as is wound upon the armature of this volt meter, gives one ohm of resistance. There are 125 inches of this wire upon the armature. Its resistance is, therefore, 62.5 ohms, and we may, therefore, say that one volt of electric pressure can push through 62.5 ohms of resistance .016 of an ampere of current.

3.5 Control rods – These are rods used in specific materials (silver, indium, cadmium or boron carbide) to control fission inside the core. Since they absorb neutrons, they are capable of controlling the chain reaction which - depending on how deep down the rods are inserted into the core - can be accelerated, slowed down or even stopped, thus changing the capacity of the reactor.

So one of the things I did while running the Freedom City Play-by-Post board was make a thread with sample starting characters. (Many of the Moderators, and some of the top players, did the same.) I gave each a very basic background, enough to get an idea of

The brushes are made in three sections, so that 20 or 40 or 60 per cent. or the whole current of a machine can be used in the arc. For the fine-weather intensity, 60 per cent. of the current of one machine is usually employed: that is, a current of 137 amp6res with an electromotive force of about 50 volts.
