A flat surface on which charts are spread out, usually with stowage space for charts and other navigating equipment below the plotting surface. One without stowage space is called a CHART TABLE.

SKIN CONDENSER

Condenser using the outer surface of the cabinet as the heat radiating medium.

SAFETY CONTROL

Device to stop unit, equipment or system if unsafe pressure and/or temperatures and/or dangerous conditions are reached.

ABRASION RESISTANCE

The ability of a material to resist surface wear.

CUTTING WEAR

Comes about when hard surface asperities or hard particles that have embedded themselves into a soft surface and plough grooves into the opposing harder surface, e.g., a journal.

ADHESIVE WEAR

Often referred to as galling, scuffing, scoring, or seizing. It happens when sliding surfaces contact one another, causing fragments to be pulled from one surface and to adhere to the other.

REMOTE REFRIGERATING SYSTEM

Refrigerating system in which condensing unit is away from space to be cooled.

AIR GAP

The space between magnetic poles, or between the rotating and stationary assemblies in a motor or generator.

JOURNAL BEARING

A sliding type of bearing having either rotating or oscillatory motion and in conjunction with which a journal operates. In a full or sleeve type journal bearing, the bearing surface is 360° in extent. In a partial bearing, the bearing surface is less than 360° in extent, i.e., 150°, 120°, etc.

CORROSION INHIBITOR

Additive for protecting lubricated metal surfaces against chemical attack by water or other contaminants. There are several types of corrosion inhibitors. Polar compounds wet the metal surface preferentially, protecting it with a film of oil. Other compounds may absorb water by incorporating it in a water-in-oil emulsion so that only the oil touches the metal surface. Another type of corrosion inhibitor combines chemically with the metal to present a non- reactive surface.

ADSORBENT FILTER

A filter medium primarily intended to hold soluble and insoluble contaminants on its surface by molecular adhesion.
