CHAIN PLATES

1. A bolt with a loop at one side 2. A small ring or barrel-shaped piece of metal inserted into a hole for reinforcement.

Some electrical systems do not use a return wire, but use another conductor instead. The earth's soil is a conductor and this can be used (hence the name). Metal car bodies are also used as a return wire for automotive circuits and are called 'earth-return' circuits. If the negative supply and one side of each lamp was connected to a metal chassis it would be an 'earth-return' circuit. Earth-return circuits are unsuitable for vessels.

Timber, metal or plastic rigging spreaders that are angled forward to increase mast support transversely and longitudinally. The stays they support are called jumper stays.

1. Application of voltage to an electrolytic capacitor, electrolytic rectifier, or semiconductor device to produce a desired permanent change in electrical characteristics as a part of the manufacturing process. 2. A process for shaping or molding sheets, rods, or other pieces of hot glass, ceramic ware, plastic, or metal by the application of pressure.

A metal cutting tool made of a material different from the shank to which it is brazed.

A rope ladder suspended from the side of a vessel and used for boarding.

Decorating a scraped metal surface with a handscraper. Also known as flaking.

A covering of sheets of metal or other material such as fire resistant composition board used to enclose all or a portion of a steam-generating unit.

A metal band that connects the outer ends of turbine blades to provide support and reduce vibration.
