Melt spinning is used to manufacture thin metal sheets or ribbons that are near amorphous or non-crystalline. The unique resulting electric and magnetic properties of melt-spun metals are a consequence of this structure as well as the composition of the alloy or metal that was used to form the ribbon.
The National Society Daughters of the American Revolution (often abbreviated as DAR or NSDAR) is a lineage-based membership service organization for women who are directly descended from a patriot of the American Revolutionary War. [1] A non-profit group, the organization promotes education and patriotism.
Magnetic-tape tape recorders record sound by magnetizing particles of ferromagnetic material, typically iron oxide (rust), coated on thin ribbons of plastic tape (or, originally, fragile paper tape). The tape coating is magnetized by dragging it over the surface of a small recording head (typically the size of a sugar cube) which contains an ...
A guide rail is a device or mechanism to direct products, vehicles or other objects through a channel, conveyor, roadway or rail system. Several types of guide rails exist and may be associated with: Factory or production line conveyors; Power tools, such as table saws; Elevator or lift shafts
Due to the different ribbon bar sizing between US and USSR decorations, Soviet ribbons were also impractical for daily wear on United States uniforms. In addition, by the 1950s at the start of the Cold War , most U.S. officers who had been awarded such medals during World War II simply chose to stop wearing them.

The first magnetic self-protection equipment was developed at the beginning of World War II because of the advent of magnetically detonated mines. This was initially a cable which was placed along the entire length to the hull of the vessel and the application of direct current produced a magnetic field that counteracted the magnetic field of the steel mass of the vessel.
A radio magnetic indicator (RMI) is an alternate ADF display providing more information than a standard ADF. While the ADF shows relative angle of the transmitter with respect to the aircraft, an RMI display incorporates a compass card, actuated by the aircraft's compass system, and permits the operator to read the magnetic bearing to or from ...
