The fuse element is made of zinc, copper, silver, aluminum, [citation needed] or alloys among these or other various metals to provide stable and predictable characteristics. [4] [5] The fuse ideally would carry its rated current indefinitely, and melt quickly on a small excess. The element must not be damaged by minor harmless surges of ...
In electrical engineering, IEC 60269 is a set of technical standards for low-voltage power fuses. [1] The standard is in four volumes, which describe general requirements, fuses for industrial and commercial applications, fuses for residential applications, and fuses to protect semiconductor devices.
Far Ultraviolet Spectroscopic Explorer (FUSE – Explorer 77) launch. The primary objective of FUSE was to use high-resolution spectroscopy at far ultraviolet wavelengths to study the origin and evolution of the lightest elements (hydrogen and deuterium) created shortly after the Big Bang, and the forces and processes involved in the evolution of galaxies, stars and planetary systems.
A research proposal is a document proposing a research project, generally in the sciences or academia, and generally constitutes a request for sponsorship of that research. [1] Proposals are evaluated on the cost and potential impact of the proposed research, and on the soundness of the proposed plan for carrying it out. [ 2 ]
A proximity fuse (also VT fuse [1] [2] [3] or "variable time fuze") is a fuse that detonates an explosive device automatically when it approaches within a certain distance of its target. Proximity fuses are designed for elusive military targets such as aircraft and missiles, as well as ships at sea and ground forces.
This simple form of burning fuse can still be found today in many modern fireworks. A version of this simple fuse is called visco fuse, and consists of the burning core coated with wax or lacquer for durability and water resistance. Early fuses for grenades also consist of a wooden plug with a longitudinal hole filled with a slow burning ...
Fuse: Cord or tube for the transmission of flame or explosion usually consisting of cord or rope with gunpowder or high explosive spun into it. (The spelling fuze may also be met for this term, but fuse is the preferred spelling in this context.) [7] Fuze: A device with explosive components designed to initiate a main charge.
A magnetic proximity fuse was patented by P.J. Eliomarkakis, (United States Patent US2434551 of January 13, 1948) [1] although similar devices had been in service for nearly a decade. It is a type of proximity fuze that initiates a detonator in a piece of ordnance such as a land mine , naval mine , depth charge , or shell when the fuse's ...
