Element window — a small window built into the fuse body to provide visual indication of a blown element. External trip indicator — similar function to striker pin, but can be externally attached (using clips) to a compatible fuse. Some fuses allow a special purpose micro switch or relay unit to be fixed to the fuse body.
Shaped like a “U” or channel to catch water (e.g., where the edge of a tile roof meets a wall). Through wall flashing Spans the thickness of the wall and directs water to weep holes. Cap flashing (drip cap) Often used above windows and doors. Drip edge A metal used at the edges of a roof. Step flashing (soaker, base flashing)
When the glass and the metal being hermetically sealed have the same coefficient of thermal expansion, a "matched seal" derives its strength from bond between the glass and the metal's oxide. This type of glass-to-metal hermetic seal is generally used for low-intensity applications such as in light bulb bases.
Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...
A cylinder fuse is a type of electrical fuse.Like other types of fuses, it is a safety device used to protect electrical devices from excessive current. [1] [2]As its name suggests, a cylinder fuse is shaped like a cylinder.
A steam boiler was fitted with a small observation window of glass and heated beyond its normal operating temperature with the water level below the top of the firebox. When water was added it was found that the pressure rose suddenly and the observation glass shattered.
