The feedback current is removed when H or L releases: this causes relay S to re-operate and the cycle to repeat, until the current in S due to the phase discriminator is less than that required to operate relay. 432. There is quite a difference of opinion as to the most practicable space velocity. There are many considerations to be taken into account in determining space velocity. 433. Unless other conditions are stated specifically, we shall use the term «state» to represent an equilibrium state. 434. Such structural changes as may take place in various metals and alloys when in service over an extended period of time, can hardly be expected to take place in the brief periods employed 552 |
