A coupling or coupler is a mechanism, typically located at each end of a rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train.
Guitar wiring refers to the electrical components, and interconnections thereof, inside an electric guitar (and, by extension, other electric instruments like the bass guitar or mandolin). It most commonly consists of pickups , potentiometers to adjust volume and tone, a switch to select between different pickups (if the instrument has more ...
Narrow gauge flat wagons, 750 mm (2 ft 5 + 1 ⁄ 2 in).Note the single buffer with a hook on the right side and a chain on the other. On some narrow-gauge lines in Europe, and on the Paris Metro, a simplified version of the loose-coupler is used, consisting of a single central buffer with a chain underneath.
With gooseneck couplers or offset shank couplers, the horizontal centerline of the coupler head is above the horizontal centerline of the coupler shank, or shaft, and the draw gear. This arrangement is designed for use with low-floor freight cars , to lift the coupler head high enough to match the couplers on other rolling stock. [ 18 ]
The first use of the Scharfenberg coupler was for the Manila MRT Line 3 in 1999. Meanwhile, the first use of the Shibata coupler was for the LRT Line 2. In the future, Shibata couplers are also expected for use on the MRT Line 7, the Metro Manila Subway, and the North–South Commuter Railway (NSCR). The NSCR is so far the only PNR line that ...
A hexaphonic pickup and a converter are usually components of a guitar/synthesizer. Such pickups are uncommon (compared to normal ones), and only a few notable models exist, like the piezoelectric pickups on the Moog Guitar. Hexaphonic pickups can be either magnetic or piezoelectric or based on the condensor principle like electronicpickups
Digital automatic coupling (DAC) is a type of railway coupling developed in the 2020's to replace the English buffers and chain couplings, initially in Europe. It resembles the Scharfenberg coupler with extra contacts to join electrical circuits (power, detection and control) and air hoses.
A pneumatic buffer with sections cut away. A buffer is a part of the buffers and chain coupler system used on the railway systems of many countries, among them most of those in Europe, for attaching railway vehicles together (in North America, rolling stock instead has draft gear built into the couplers).
