(SPOC): Rescue coordination centres and other established and recognised national points of contact that can accept responsibility to receive Cospas-Sarsat alert data to enable the rescue of persons in distress.

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.
|
ELASTOHYDRODYNAMIC LUBRICATION
In rolling element bearings, the elastic deformation of the bearing (flattening) as it rolls, under load, in the bearing race. This momentary flattening improves the hydrodynamic lubrication properties by converting point or line contact to surface-to-surface contact.
|
ANTI-FRICTION BEARING
A rolling contact type bearing in which the rotating or moving member is supported or guided by means of ball or roller elements. Does not mean without friction.
|
BRINELLING
Permanent deformation of the bearing surfaces where the rollers (or balls) contact the races. Brinelling results from excessive load or impact on stationary bearings. It is a form of mechanical damage in which metal is displaced or upset without attrition.
|
CAPILLARITY
A property of a solid-liquid system manifested by the tendency of the liquid in contact with the solid to rise above or fall below the level of the surrounding liquid; this phenomenon is seen in a small bore (capillary) tube.
|
NONCONTACT BEARING
A bearing in which no solid contact occurs between relatively moving surfaces.
|
OXIDATION STABILITY
Ability of a lubricant to resist natural degradation upon contact with oxygen.
|
JET CONDENSER
A direct contact heat exchanger in which steam to be condensed comes into direct contact with the cooling water (cold condensate) which is usually introduced in the form of a spray from a jet.
|
LANDFALL
The first sighting of land when approached from seaward. By extension, the term is sometimes used to refer to the first contact with land by any means, as by radar.
|
HYDROFOIL
A craft more or less similar to the Hovercraft insofar as it flies over water and thus eliminates friction between the water and the hull. Under acceleration it rises above water but remains in contact with the surface through supporting legs.
