XYZ Coheritor
A coheritor or a cohesor is a primitive type of bridge receiver on the telegraph.
The coheritor was only fit for the reception of messages in the Morse Code.
For the reception of wireless telephony and of AM radio, this device was inadequate.
XYZ Construction and functioning
The cohesor consists of a tenuous tube of glass with two electrodes, full, without pressure, of metal lime (FeNi).
One side of the cohesor is connected with the antenna, the other with the earth.
The high electric resistance inhibits an electric current from a source of energy connected parallel to the cohesor.
But under the influence of a radio wave, the dust is cohered, and the cohesor allows for the easy passage of the current.
This corrent may, for example, ring a bell or control a relay.
The cause of this effect is the crosshairs that are running between the sheets of metal and which make the pieces coagulated.
If it strikes at the bottom of the tube, it's the opposite, and it's the previous situation.
