A metaphor is a figure of speech that identifies something as being the same as some unrelated thing for rhetorical effect, thus highlighting the similarities between the two. While a simile compares two items, a metaphor directly equates them, and does not use like or as as does a simile. One of the most commonly cited examples of a metaphor in English literature is the . All the world's a stage  monologue from As You Like It : All the world's a stage, And all the men and women merely players; They have their exits and their entrances[...]. âWilliam Shakespeare, As You Like It, 2/7. This quotation expresses a metaphor because the world is not literally a stage.
Hydromechanical Spring Clamping Systems I Series ZSF/ZDF mechanical clamping-hydraulic releasing high operational safety, leak-proof and robusteconomical clamping solution General The hydromechanical spring clamping systems work through interaction of mechanical and hydraulic systems.
Notice that the hydraulic power unit is dedicated to this machine. Unlike pneumatic circuits, most hydraulic systems have a power unit that only operates one machine. (As mentioned before, some new installations are using a central hydraulic power source with piping throughout the plant to carry pressurized and return fluid.)
