Sonication

 Sonication is the act of applying sound energy to agitate particles in a sample, for various purposes such as the extraction of multiple compounds from plants, microalgae and seaweeds.

flame arrester

 A flame arrester (also spelled arrestor), deflagration arrester, or flame trap is a device that stops fuel combustion by extinguishing the flame.

Siping

 

Siping is a process of cutting thin slits across a rubber surface to improve traction in wet or icy conditions.

Siping was invented and patented in 1923 under the name of John F. Sipe. The story told on various websites is that, in the 1920s, Sipe worked in a slaughterhouse and grew tired of slipping on the wet floors. He found that cutting slits in the tread on the bottoms of his shoes provided better traction than the uncut tread. Another story is that he was a deckhand and wanted to avoid slipping on a wet deck.

pinion

A pinion is a round gear used in several applications:

• usually the smallest gear in a gear drive train, although in the case of John Blenkinsop's Salamanca, the pinion was rather large. In many cases, such as remote controlled toys, the pinion is also the drive gear.
• the smaller gear that drives in a 90-degree angle towards a crown gear in a differential drive.
• the small front sprocket on a chain driven motorcycle.
• the round gear that engages and drives a rack in a rack and pinion mechanism and against a rack in a rack railway.
• in the case of radio-controlled cars with an engine (i.e. nitro) this pinion gear can be referred to as a clutch bell when it is paired with a centrifugal clutch.

bushing

A bushing or rubber bushing is a type of vibration isolator. It provides an interface between two parts, damping the energy transmitted through the bushing. A common application is in vehicle suspension systems, where a bushing made of rubber (or, more often, synthetic rubber or polyurethane) separates the faces of two metal objects while allowing a certain amount of movement. This movement allows the suspension parts to move freely, for example, when traveling over a large bump, while minimizing transmission of noise and small vibrations through to the chassis of the vehicle. A rubber bushing may also be described as a flexible mounting or antivibration mounting.
