Abstract: Use, in laminated cores for electrical apparatuses and machines, which cores are to conduct electromagnetically induced magnetic alternating fluxes, of a thin plate of a ferritic stainless steel which besides Fe contains in weight-%, 10-30 Cr, 4-12 Al and Si from traces and up to max 0.7 Si.

Abstract: A method for cutting a glass reflector and a glass reflector produced by a cutting process. The method typically includes forming a fluid jet by ejecting a mixture of fluid and abrasive at an initial pressure, creating a pierce hole in the glass reflector with the fluid jet at the initial pressure, and cutting a ventilation hole in the glass reflector by moving the fluid jet from the pierce hole along a cutting path. The method may also include, after cutting the pierce hole and before cutting the ventilation hole, raising the pressure of the fluid jet from the initial pressure to an increased pressure.
