Diagram of a fireplace hand-bellows. A bellows or pair of bellows is a device constructed to furnish a strong blast of air.The simplest type consists of a flexible bag comprising a pair of rigid boards with handles joined by flexible leather sides enclosing an approximately airtight cavity which can be expanded and contracted by operating the handles, and fitted with a valve allowing air to ...
In the process industry, a standard set of symbols is used to prepare drawings of processes.

These are dotted lines, but a long line of 10–20 mm, then a 1 mm gap, then a small line of 2 mm. 2H pencil; Type H lines are the same as type G, except that every second long line is thicker. These indicate the cutting plane of an object. 2H pencil; Type K lines indicate the alternate positions of an object and the line taken by that object ...
