A Look to the Future

In the past, gas analysis took a long time. Now it can be done in moments. This is done in a flow tube (387) in which the particles generated by the ionization process are accelerated, so that the light ions move faster than the heavy ions, and the separation process between the types of matter occurs according to their mass.

The printed circuit industry has revolutionized the creation and manufacture of precision devices, and has led to the possibility of arranging the conductive paths without entanglement.

287 - High-speed spectrometer.

This process is done by drawing an enlarged circuit, which is then reduced by photocopying methods. This results in printing electrical conductors (288) on insulating boards, a large number of which can be easily manufactured. When the components of the circuit are soldered, these conductors play the role of the connecting wires in it.

Printed circuits contribute to the production of independent circuits in themselves, and in maintenance and repair operations where the entire circuit is replaced with a new one.

Electronic computers contain thousands of logical elements, such as those used in the "OR" gate or the "AND" gate. These types and others are tested electronically and very quickly by a machine that supplies them with appropriate signals and records their output (389). Then the circuits that produce some errors are put aside in preparation for their repair.
