The market for quick couplers is mainly supplied by a large number of small and medium-sized enterprises. Many of the manufacturers of quick couplers are small, flexible and innovative, leading to the wide variation in design concepts. Many Original Equipment Manufacturers (OEMs) of construction equipment market a range of quick couplers.
Transposition is the periodic swapping of positions of the conductors of a transmission line, in order to reduce crosstalk and otherwise improve transmission. In telecommunications this applies to balanced pairs whilst in power transmission lines three conductors are periodically transposed.
When equipped with self-sealing valves, quick connect fittings will, upon disconnection, automatically contain any fluid in the line. However, this depends on the type of coupling, such as single shut-off, double shut-off, or straight-through designs, which determine whether fluid retention occurs.
Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit. An essential feature of ...
Nipples with mating safety couplings. Also known as pneumatic couplings, quick disconnects, air couplers, quick connect couplers, and quick couplers, hand-operable air-line fittings allow manual disconnection of gas supply lines, including compressed air and breathable air (a subset of breathing gases).
Transmission line cables require impedance matching to carry electromagnetic signals with minimal reflections and power losses. The distinguishing feature of most transmission line cables is that they have uniform cross-sectional dimensions along their length, giving them a uniform electrical characteristic impedance. Signal terminators are ...
In 1991, the firm entered a joint venture with Sumitomo of Japan to produce excavators, which ended in 1998. [7] Two years later, a JCB factory was completed in Pooler near Savannah, Georgia, in the US, and in 2012 a factory was opened in Brazil. [8] In 2005, JCB bought a company, purchasing the German equipment firm Vibromax.
A PTO at the rear end of a farm tractor A PTO (in the box at the bottom) in the center of the three-point hitch of a tractor. A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.
