Vibration isolation. Vibration isolation is the prevention of transmission of vibration from one component of a system to others parts of the same system, as in buildings or mechanical systems. [1] Vibration is undesirable in many domains, primarily engineered systems and habitable spaces, and methods have been developed to prevent the transfer ...
Harmonic balancer lower pulley on a four-cylinder engine. A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. This device must be an interference fit to the crankshaft in order to operate in an effective manner.
The largest air-insulated Van de Graaff generator in the world, built by Dr. Van de Graaff in the 1930s, is now displayed permanently at Boston's Museum of Science. With two conjoined 4.5 m (15 ft) aluminium spheres standing on columns 22 ft (6.7 m) tall, this generator can often obtain 2 MV (2 million volts).
Installation in rear suspension. André Hartford dampers were made in four sizes, according to vehicle weight and intended use. These were the combination of two disk diameters: 3 + 1 ⁄ 4 inches (83 mm) and 4 + 1 ⁄ 2 inches (110 mm) and as either single or multiplate designs. Single dampers had two friction surfaces: a single arm on one ...
Diesel generator on an oil tanker. The packaged combination of a diesel engine, a generator, and various auxiliary devices (such as base, canopy, sound attenuation, control systems, circuit breakers, jacket water heaters, and starting system) is referred to as a "generating set" or a "Genset" in short. Set sizes range from 8 to 30-kW (also 8 to ...
Damper (flow) Opposed blade dampers in a mixing duct. A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature ...

Mercury battery. A mercury battery (also called mercuric oxide battery, mercury cell, button cell, or Ruben-Mallory[ 1]) is a non-rechargeable electrochemical battery, a primary cell. Mercury batteries use a reaction between mercuric oxide and zinc electrodes in an alkaline electrolyte. The voltage during discharge remains practically constant ...
