The current developments of automatic processes are, however, different from the old ones. The “automation” 20th century is distinct from the mechanization of the 18th and 19th centuries in as much as mechanization was applied to individual operations, whereas “automation”is concerned with the operation and control of a complete producing unit. And in many, though not all, instances the element of control is so great that whereas mechanization displaces muscle, “automation” displaces brain as well.The distinction between the mechanization of the past and what is happening now is, however, not a sharp one. At one extreme we have the electronic computer with its quite remarkable capacity for discrimination and control, while at the other end of the scale are “transfer machines”, as they are now called, which may be assimple as a convey or belt to another. An automatic mechanism is one which has a capacity for self-regulate; that is, it can regulate or control the system or process without the need for constant human attention or adjustment. Now people often talk about “feedback” as being an essential factor of the new industrial techniques, upon which is based an automation self-regulating system and by virtue of which any deviation in the system from desired conditions can be detected, measured, reported and corrected. When “feedback” is applied to the process by which a large digital computer runs at the immense speed through a long series of sums, constantly rejecting the answers until it finds one to fit a complex set of facts that have been put to it, it is perhaps different in degree from what we have previously been accustomed to machines. But “feedback”, as such, is a familiar mechanical conception. The old-fashioned steam engine was fitted with a centrifugal governor, two balls on levers spinning round and round an upright shaft. If the steam pressure rose and the engine started to go too fast, the increased speed of the spinning governor caused it to rise up the vertical rod and shut down a valve. This cut off some of the steam and thus the engine brought itself back to its proper speed.The mechanization, which was introduced with the Industrial Revolution, because it was limited to individual processes, required the employment of human labor to control each machine as well as to load and unload materials and transfer them from one place to another. Only in a few instances were processes automatically linked together and was production organized as a continuous flow.In general, however, although modern industry has been highly mechanized ever since the 1920s, the mechanized parts have not as a rule been linked together. Electric-light bulbs, bottles and the components of innumerable mass-produced articles are made in mechanized factories in which a degree of automatic control has gradually been building up. The development of the electronic computer in the 1940s suggested that there were a number of other devices less complicated and expensive than the computer which could share the field of mechanical control. These devices mechanical, pneumatic and hydraulic have been considerably developed in recent years and will continue to advance now that the common opinion is favoring the extension of “automation”. Electronic devices, of course, although not the sole cause of what is happening, are nevertheless in a key position. They are gaining in importance and unquestionably hold out exceptional promise for development in the future.
