A hollow cone with a tube extending from the smaller end and that is designed to catch and direct a downward flow.

A physical object that is intended to induce a reaction in a process fluid by heating it.

Is an artefact which is necessary, useful or desirable, especially for living or working but is not a tool for production.

A physical object that by the fusing of one or more of its specially designed and proportioned components, opens the circuit in which it is inserted by breaking the current when this exceeds a given value for a sufficient time.

A plug capable of being melted and fused.

Galvanic isolation is the principle of isolating functional sections of electric systems so that charge-carrying particles cannot move from one section to another.

A chromatograph where gas is injected directly into one or more separation columns.

An analyser which analyses the composition of gaseous mixture with two or more components.

A detector that is intended to sense the presence of a specified concentration of a gas.

A distributor intended to distribute or redistribute a vapour.

An internal combustion engine that is a reciprocating engine in which gaseous fuel is mixed with air to form a combustible mixture in a cylinder which is fired by spark ignition.

A chromatograph where a liquid sample is injected and evaporated and subsequently carried to one or more separation columns.

A turbine that compresses air which is then mixed with fuel for combustion and expansion through a turbine section to generate relatively high power output for either mechanical drive or power generation.

A circuit-breaker in which the arc develops in a blast of gas.

A seal that is one or more closed loops of deformable material used between mating surfaces which have only very limited movement relative to each other.
