Viessmann seized these growth opportunities and developed into a medium-sized industrial enterprise with 1,400 employees. The 1970s were a time of expansion. In 1972, Viessmann opened its first foreign factory in Faulquemont (France), followed by Waterloo, Ontario (Canada), the first site outside Europe, in 1978. With the development of new ...
The AN/URM-25 was part of a series of vacuum tube-based signal generators built for the U.S. military in the early Cold War-era.. Today they are collected and used by vintage amateur radio and antique radio enthusiasts who say they provide reasonably high accuracy and stability for a low cost, with build quality reflecting tough military construction requirements and standards.
A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration ) or used to drive a steam turbine ( combined cycle ).
A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
A ram air turbine (RAT) is a small wind turbine that is connected to a hydraulic pump, or electrical generator, installed in an aircraft and used as a power source. The RAT generates power from the airstream by ram pressure due to the speed of the aircraft. It may be called an air driven generator (ADG) on some aircraft. [1]
A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG). Armature: The power-producing component of an electrical machine. In a generator, alternator, or dynamo, the armature windings generate the electric current, which provides power to an external circuit.
Wiesmann MF30. The Wiesmann MF30 is the first Wiesmann model ever built, with cars entering production in 1993. [18]The MF30 is powered by a six-cylinder M54B30 engine borrowed from BMW, with a capacity of 2979 cm 3 and a power output of 170 kW (228 hp; 231 PS) at 5,900 rpm and 300 N⋅m (221 ft⋅lbf) of torque at 3,400 rpm.
Manual up/down controls for elevator technicians, to be used in inspection mode, for example. An independent service/exclusive mode (also known as "car preference"), which will prevent the car from answering to hall calls and only arrive at floors selected via the panel. The door should stay open while parked on a floor.
