A covering or coating applied to a structure to make it weathertight.

A mechanical device made for keeping objects firmly in place or position, temporary or permanently.

An artefact class that contains classes of artefacts or physical resources required for a purpose.

Any mechanical or electrical device that transmits or modifies energy to perform or assist a cleaning operation in the performance of human tasks.

A net in an open-meshed fabric twisted, knotted, or woven together at regular intervals made for climbing.

A timepiece for the measurement of time.

An analysing instrument that is intended to determine the cloud point of a fluid.

A transmission that is intended to transmit energy between two shafts providing the capability to connect and disconnect the shafts.

A gravity separator where two liquid substances separates and where the substance with the less gravity can be skimmed off.

The temperature at which either the fuel specimen ceases to flow through a filter within 60 seconds or fails to return into the test jar is recorded as the Cold Filter Plugging Point.

An artefact and a cooling appliance comprising a thermally insulated compartment and a heat pump-chemical or mechanical means-to transfer heat from it to the external environment, cooling the contents to a temperature below ambient.

A support which is a cylindrical or slightly tapering body of considerably greater length than diameter, erected vertically as a support.

An instrument that indicates either a) magnetic bearings by alignment of its needle on the magnetic poles, or b) reference bearing by radio signal, or c) change of orientation in relation to a gyromaintained line.

A device compensating for axial or radial movement between two elements that is connected.

A physical object that is driven by a prime mover by which energy is either constantly or periodically added to an amount of gas in order to increase its pressure.

A physical object that can store data and program(s) that operates on the data. A general purpose computer can be programmed to solve any reasonable problem expressed in logical and arithmetical terms.

A transmitter measuring how much of a given substance there is mixed with another substance and transmit a signal proportional to the measured level.

A cooler that is intended to change a vapour to liquid.

A detecting element or probe that is used with a conductivity meter to measure the conductivity of a liquid.

A transmitter that is producing a standardized output signal dependent of a received input signal from a conductivity meter.

A transmitter that is intended to measure and transmit conductivity.

A regulator ensuring constant volume in a HVAC system to reduce noise

A mechanical switching device having only one position of rest, operated otherwise than by hand, capable of making, carrying and breaking currents under normal circuit conditions including operating overload conditions.

A pressure vessel with internal packing intended to effect the main stream by introducing counter flow of a regenerative liquid or gas. Dehydration of gas by use of glycol is a typical application.

A physical object intended to contain something.
