Although traditionally Manet has been related as the master and Morisot as the follower, there is evidence that their relationship was a reciprocating one.

Although many manufacturers licensed the design, including Citroën with their M35 and GS Birotor, using engines produced by Comotor, General Motors, which seems to have concluded that the Wankel engine was slightly more expensive to build than an equivalent reciprocating engine, although claiming having solved the fuel economy issue, but failed in obtaining acceptable exhaust emissions, and Mercedes-Benz which used it for their C111 concept car, only Mazda has produced Wankel engines in large numbers.

Although the use of water power gave way to steam power in many of the larger mills and factories, it was still used during the 18th and 19th centuries for many smaller operations, such as driving the bellows in small blast furnaces ( e. g. the Dyfi Furnace ) and gristmills, such as those built at Saint Anthony Falls, which uses the 50-foot ( 15 m ) drop in the Mississippi River.

Although the principle of the crank had long been known, Pickard managed to obtain a 12-year patent in 1780 for the specific application of the crank to steam engines ; this was a setback to Boulton and Watt who got round the patent by applying the sun and planet motion to their advanced double-acting rotative engine of 1782.

Although such heaters are usually termed " boilers " in some countries, their purpose is usually to produce hot water, not steam, and so they run at low pressure and try to avoid actual boiling.

Although the idea of running freight carts in tracks carved into rock dates back at least as far as ancient Greece and wooden-railed wagonways originated in Germany in the 16th century, the first use of steam locomotives was in Britain.

Although the lever safety valve was convenient, it was too sensitive to the motion of a steam locomotive.

Although deadweight safety valves had a short lifetime on steam locomotives, they remained in use on stationary boilers for as long as steam power remained.

Although showy polished brass covers over safety valves had been a feature of steam locomotives since Stephenson's day, the only railway to maintain this tradition into the era of pop valves was the GWR, with their distinctive tapered brass safety valve bonnets and copper-capped chimneys.

Although the original author of the song is unknown, Shosholoza is a traditional miner's song, originally sung by groups of men from the Ndebele ethnic group that travelled by steam train from their homes in Zimbabwe to work in South Africa's diamond and gold mines.

Although the rest of the branch was electrified by London Underground before operations were taken over from British Railways, trains on the section north of Epping continued to be hauled by steam locomotives as a separate shuttle service.

Although the Buckinghamshire Railway Centre's steam trains run on the sidings which were disconnected from the network in 1967, the station still has a working railway line passing through it which is also used for occasional special passenger trains from Aylesbury in connection with events at the Buckinghamshire Railway Centre.

Although the company was very successful as a producer of steam locomotives, its transition to the production of diesels was far less so.

Although the parallel steam railroads were often annoyed by the competition, the interurbans could be valuable to them as connections.

Although Havok initially rebuffs her advances, hesitant to " start up again after " everything that happened between them, Lorna says that he needs to " blow off some steam " and the scene ends with them kissing.

Although the 13th Division and 7th ( Lahore ) Division hung on to their gains, the Turkish counter-attack had taken the steam out of the Anglo-Indian offensive.

Although the developments that enabled this transformation – roller spinning, the factory system and the industrial steam engine – often had Birmingham origins, they had little role in Birmingham's own expansion.

Although, in these early years, engines came in a number of configurations, typically Q < sub > H </ sub > was supplied by a boiler, wherein water was boiled over a furnace ; Q < sub > C </ sub > was typically a stream of cold flowing water in the form of a condenser located on a separate part of the engine.

Although the concept was proven sound and the 500 megawatt engine finished a successful test run in 1961, no airworthy device was ever completed.

Although Babbage's design was technically feasible, no one had built a mechanical device to such exacting standards before, so the engine proved to be much more expensive than anticipated.

Although unsuccessful, he made a two-stroke toy engine in 1919, called Des Knaben Wunsch —" the boy's desire ".

Although the engine produces just 92 millinewtons ( 0. 331 ounce-force ) thrust at maximum power ( 2, 100W on DS1 ), the craft achieved high speeds because ion engines thrust continuously for long periods.

Although listed under the general heading of " panoramas " in the sales catalogues of the time, those films shot straight forward from in front of a railway engine were usually specifically referred to as " phantom rides ".

Although K-Meleon 0. 9. 13 is based on Gecko 1. 7. 13, which is now obsolete, a simulation of it ( called " K-Meleon0. 9. 13-ud3-1. 8. 0. 7 ") has been made that is based on a current " k-meleon. exe " and a recent 1. 8. 0. x Gecko rendering engine to allow people who prefer the older K-Meleon 0. 9 interface to update their browsing to current security standards.

Although MATLAB is intended primarily for numerical computing, an optional toolbox uses the MuPAD symbolic engine, allowing access to symbolic computing capabilities.

Although compact, for use in a cramped submarine, this design of engine was not repeated.

Although this is a relatively fast movement, perhaps a second or so while transmission is in neutral, it allows the engine speed to drop and synchronize engine and transmission revolutions relative to the road speed.

Although it is relatively easy to derive a 90 ° V6 from an existing V8 design by simply cutting two cylinders off the engine, this tends to make it wider and more vibration-prone than a 60 ° V6.

Although in two dimensions the seal system of a Wankel looks to be even simpler than that of a corresponding multi-cylinder piston engine, in three dimensions the opposite is true.

Although engineering studies of all of these designs were made, only the solid-core engine was ever built.

Although he designed a basic form of internal combustion engine, fueled by gunpowder, he never successfully built one.

Although he also developed a type of rotary aircraft engine, he did not create and fly a powered fixed-wing aircraft.

Although it was the popularity of the Oldsmobile division vehicles that prompted this change, declining sales of V8 engines would have made this change inevitable as all but the Chevrolet version of the 350-cubic-inch engine were eventually dropped.

Although it was only fractionally longer than the contemporary Volkswagen Beetle, Time said the length of its hood over the front-mounted engine made " the difference seem considerably more ", adding that the car " resembles a sawed-off station wagon, with a long, low hood and swept-up rear, and is faintly reminiscent of the original Studebaker Avanti.
