Donkey, английский
- Also known as a yarder (22).
- A small engine used for hoisting or hauling. donkey’s breakfast: seaman’s slang for the straw which formerly stuffed the mattresses of those who had beds instead of hammocks. don’t give up the ship: on june 1, 1813, two 38- gun frigates met in a duel off boston. in size, tonnage, and armament the ships were evenly matched, so the outcome depended on morale, experience, and training, where there were marked differences. • sir philip bowes vere broke had been in command of hms shannon for over six years, during which he had obsessively trained his gun captains and crews to fire individually as their weapons came to bear—some being detailed to aim at the enemy’s helm and quarterdeck to destroy command and control, others at its gunports to inflict maximum damage on offensive capability. confidence was high, and the british crew was anxious to come to grips with the americans. • in contrast, james lawrence, who had recently been promoted to captain, had just taken command of uss chesapeake, a ship with a bad luck reputation, and a surly rag-tag crew who did not know their captain and had not had time to train together as a team. some even staged a minor mutiny, refusing to man the guns until the purser issued chits for prize money they claimed was owing to them. in the first exchange of fire, virtually everyone on chesapeake’s quarterdeck was killed or wounded, including the captain, his executive officer, the lieutenant of marines, three midshipmen, and both helmsmen. lawrence’s wounds were mortal but, as he was being carried below, he shouted defiantly “tell the men to fire faster and not to give up the ship; fight her until she sinks ... (or) blow her up.” brave words were not enough. within 15 minutes, half of chesapeake’s crew and every one of her officers had been killed or wounded. the butcher bill was exceptionally high, probably because chesapeake’s upperworks had been built of easily-splintered pine when more shotresistant oak was not available. despite defeat and death, lawrence entered the immortal pantheon of naval heroes since his dying order became the unofficial motto of the united states navy. don’t spoil the ship: see spoil the ship.

- [1] a display of signal flags. [2] the vertical edge of a flag alongside the mast. [3] the half of a flag nearest to the mast. [4] to lift something. [5] a lifting apparatus.
- The windlass mechanism incorporated as an integral part of a power-driven drilling machine used to handle, hoist, and lower drill-string equipment, casing, pipe, etc., while drilling, or to snake the drill from place to place.
- The act or process of lifting drill string, casing, or pipe out of a borehole.
- A power-driven windlass for raising ore, rock, or other material from a mine and for lowering or rais ing men and material.

Compressed, английский
- Сжат; уплотнен

Combustion, английский
- Сгорание; горение
- Горение, сожжение
- Any chemical process that produces light and heat as either glow or flames.
- Burning, &c. (see spontaneous combustion.)
- Сгорание, сжигание, горение, возгорание
- Сгорание. химическая реакция, при: которой вещество соединяется с кислородом с выделением тепла: «горение». сгорание топлива, содержащего углерод и водород, считается полным, если цроисходит полное окисление этих двух элементов до углекислого газа и воды. неполное сгорание может привести к тому, что: 1) в золе остается значительное количество углерода; 2) часть углерода выделяется в виде окиси углерода; и 3) молекулы топлива реагируют с образованием ряда продуктов более сложного состава по сравнению с исходными молекулами топлива, и если эти продукты не сгорают, они выделяются в виде дыма. сгорание летучих продуктов может протекать более полно, если сверху на слой топлива подается так называемый вторичный воздух (воздух, пропускаемый через слой топлива, называется «первичным»). воздух сверх количества, теоретически необходимого для полного сгорания (избыточный воздух), следует подавать с минимальным избытком, чтобы` избежать неоправданных потерь тепла с дымовыми газами, слабой теплопередачи и окисления двуокиси серы в трехокись. перенасыщенное сгорание происходит в системе, где топливо подается сверху на раскаленный слой топлива. такая система характеризуется тенденцией к образованию дыма. тороидальное (кольцевое) сгорание происходит в системе, где в печи поддерживается вихревой поток; это увеличивает время пребывания топлива в печи и настолько улучшает горение, что дополнительной подачи воздуха, требуется мало или не требуется совсем. 40
- A combustion reaction involves a substance combining with an oxidizer, releasing a large amount of heat (exothermic) and produces a flame. the heat produced can make combustion self-sustaining. an oxidizer is a compound that takes electrons in a reaction and can promote or initiate combustion. oxygen and chlorine are examples of oxidizers. when oxygen is available in sufficient amounts, complete combustion occurs. if a hydrocarbon undergoes complete combustion, carbon dioxide and water vapor are produced. combustion reactions can be oxygen starved or can involve excess oxygen. in an oxygen starved combustion reaction, a combustion reaction has a limited oxygen supply and incomplete combustion occurs. in an environment of combustion in excess air, the amount of oxygen supplied to the combustion reaction is more than is needed for complete combustion and can lead to a hotter, faster burning fire.
- A chemical process of oxidation that occurs at a rate fast enough to produce heat and usually light in the form of either a glow or flame.
- The chemical process of oxidation that occurs at a rate fast enough to produce heat and usually light in the form of either a glow or flame.
