Abstract: An air vent for an interior of a motor vehicle, the air vent including a housing including a longitudinal housing axis; an air outlet opening formed by the housing; at least one air louver that is arranged in the housing and that directs an air flow that exits from the air outlet opening, wherein the air outlet opening is provided with an expanded metal cover that includes loops that are enveloped by bars that include bar walls, wherein the bar walls are arranged at a bar wall angle relative to the longitudinal hosing axis, wherein the at least one air louver is arranged at an air louver angle relative to the longitudinal housing axis and includes a proximal air louver edge that is proximal to the expanded metal cover and a distal air louver edge that is distal from the expanded metal cover.

Abstract: A magnetic recording medium which consists of at least two layers cast one on top of the other is described, the lower layer containing acicular magnetic pigments having a field strength of 5-40 kA/m and a magnetization of 20-70 nTm3/g and the upper layer containing a high-density metal powder dispersion. After application of the layers, the magnetic recording medium is subjected to a magnetic disorientation treatment while the layers are in the wet state, so that said recording medium has virtually no magnetic and mechanical anisotropy. The magnetic recording medium produced in this manner is particularly suitable for floppy disks having a high storage capacity of substantially more than 100 megabytes.
