This allows for more precise control of shift points, shift quality, lower shift times and manual control. The first five-speed automatic was the ZF 5HP18 transmission, debuting in 1991 on various BMW models. The first six-speed automatic was the ZF 6HP26 transmission, which debuted in the 2002 BMW 7 Series (E65).
Miniature oil-filled Coilover shock components for scale cars. A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.
Prasad et al. [11] have developed a honeycomb damping plate concept, based on particle damping technique, to reduce low-frequency vibration amplitude from an onshore wind turbine generator. Prasad et al. [12] have suggested three different strategies to implement particle dampers in a wind turbine blade to reduce the vibration amplitude.
At working speed they are just normal extractor fans. At continuous speed they extract typically 5 to 10 l/sec and use little electricity, 1 or 2 watts, for low annual cost. Some have humidity sensors to control trickle operation. They have the advantage of ensuring ventilation and preventing build-up of humidity.
The main distinction between these instruments and other wind instruments is the way in which they produce sound. [1] All woodwinds produce sound by splitting the air blown into them on a sharp edge, such as a reed or a fipple. Despite the name, a woodwind may be made of any material, not just wood.
AC electric motors can be run in fixed-speed operation determined by the number of stator pole pairs in the motor and the frequency of the alternating current supply. AC motors can be made for "pole changing" operation, reconnecting the stator winding to vary the number of poles so that two, sometimes three, speeds are obtained.
A gas stove is a stove that is fuelled by combustible gas such as natural gas, propane, butane, liquefied petroleum gas, syngas, or other flammable gas. Before the advent of gas, cooking stoves relied on solid fuels such as coal or wood. The first gas stoves were developed in the 1820s and a gas stove factory was established in England in 1836.
Gust locks prevent wind from causing unexpected movements of the control surfaces and their linked controls inside the aircraft, as well as aircraft doors on some aircraft; otherwise, wind gusts could cause possible damage to the control surfaces and systems, or to nearby people, cargo, or machinery.
