Michael Morpurgo, author. A child needs to feel from the very start that she or he is wanted and loved. They should grow up in the soil of affection of care. There is no replacement for that, it is the most important thing.
American bugler in the Navy, 1917. The bugle is a very simple brass instrument. It has no valves or other mechanisms, the only way the player has to control the pitch is changing the shape of his lips. This means that only notes from the harmonic series can be played.
Direct-acting relief valves often are quite noisy due to the high velocity of the fluid bypass and the instability inherent in their design. Direct-acting relief valves are not normally used on industrial hydraulic systems, except for those with flows under 3 gpm, and as pilot control devices.
