摘要： Yoke formed by a stack of magnetic laminations 4 that have mutually parallel edge notches 7 with open lips, these being located at least in the corners of the inductor.These notches are preferably spaced apart by a few mm, but the separating interval may be higher, from 1 cm and beyond, without however exceeding about 5 cm. They start at the lamination edges and extend, preferably along straight lines, towards the interior over a distance that depends on the environment of the inductor. They are produced by removing material so that each notch 7 has non-touching lips (therefore open lips), even preferably at discrete points, so as to prevent offering bridges for the circulation of eddy currents thereat.The invention applies to the production of heating inductors, by controlling the thermal behaviour of the inductors by simple means that prevent them from overheating.
摘要翻译：由一堆磁性层叠体4形成的轭体，它们具有开口的相互平行的边缘凹口7，它们至少位于电感器的拐角处。这些凹口优选地间隔开几毫米，但是分离间隔可以更高，不超过约5厘米，不超过1厘米。它们在层压边缘处开始，优选地沿直线延伸到取决于电感器的环境的距离内部。它们通过去除材料制成，使得每个凹口7具有非接触的唇缘（因此开口），甚至优选地在离散的点处，以便防止为其涡流的循环提供桥梁。本发明通过控制电感器的热行为，通过简单的手段来防止过热，从而适用于制造加热电感器。

摘要： A vacuum deposition facility for continuously depositing, on a running substrate, coatings formed from metal or metal alloy, the facility including—a vacuum chamber and a device for running the substrate through the vacuum chamber along a given path, wherein the vacuum chamber further includes:

a central casing including a substrate entry and a substrate exit located on two opposite sides of the central casing and a vapor jet coater, the inner walls of the central casing being suited to be heated at a temperature above the condensation temperature of the metal or metal alloy vapors,
a vapor trap in the form of an external casing located at the substrate exit of the central casing, the inner walls of the vapor trap being suited to be maintained at a temperature below the condensation temperature of the metal or metal alloy vapors.

摘要： A method for manufacturing direct reduced iron wherein iron ore is reduced in a direct reduction furnace by a reducing gas, the reducing gas exiting the furnace through the top as a top reduction gas. The top reduction gas is captured and at least partly subjected to a CO2 recovery step during which it is divided into two streams, a CO2-rich stream and a CO2-poor stream. The CO2-rich stream is subjected to an alkanol production step to produce an alkanol product.
