An eddy current separator (ECS) is a machine that uses a powerful magnetic field to separate non-ferrous metals from an input waste or ore stream. The device makes use of eddy currents to effect the separation. Non-ferrous metals typically separated by an ECS include aluminum, copper and die-cast metals. [1]
Kosmoid Locks was registered in January 1904, as a result of an agreement between Shiels and John Smalley Campbell, an American physician and dentist then resident in London, who like Shiels was a sometime inventor on the side, with over 20 patents registered at the U.S. Patent office, [5] some relevant to dentistry but a significant subset (9 of 22 listed) related to locks.
To keep the wire taut when changing the product, it is fixed to a wire parking pin of the machine. This wire parking pin can either be a clamp or a copy of a post that is wrapped at the coil similar to the termination process. Before the winding starts and after terminating the start wire post, the wire to the parking pin needs to be cut.
At these mines, a device called a Wetherill's Magnetic Separator (invented by John Price Wetherill, 1844–1906) [4] was used. In this machine, the raw ore, after calcination was fed onto a conveyor belt which passed underneath two pairs of electromagnets under which further belts ran at right angles to the feed belt. The first pair of balls ...
Fine copper wire mesh or gauze provided better surface contact with less segment wear, but gauze brushes were more expensive than strip or wire copper brushes. Modern rotating machines with commutators almost exclusively use carbon brushes, which may have copper powder mixed in to improve conductivity.
Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through one or more dies. There are many applications for wire drawing, including electrical wiring, cables, tension-loaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments.
Electrostatic Separator. An electrostatic separator is a device for separating particles by mass in a low energy charged beam.. An example is the electrostatic precipitator used in coal-fired power plants to treat exhaust gas, removing small particles that cause air pollution.
Metal laboratory sieves An ami shakushi, a Japanese ladle or scoop that may be used to remove small drops of batter during the frying of tempura ancient sieve. A sieve, fine mesh strainer, or sift, is a tool used for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet ...
