Abstract: A fragrance dispenser has a housing portion (1), through which an air discharge passage (12) extends, and a cartridge (2) carrying a fragrant substance and having vents (15, 16) for allowing air to pass for entraining fragrance from the cartridge (2). The cartridge (2) is removably mounted and rotatably adjustable about an axis of rotation (17) between a first position for allowing no or little air to pass through and a second position for allowing more air to pass through than in the first position. The cartridge (2) is removable in a direction transverse to the axis of rotation (17) and contains a granular fragrance carrier substrate. A domestic appliance including such a dispenser and a cartridge for use therein are also described.

Abstract: A color television camera has several pick-up tubes (T1, T2, T3) which are arranged substantially horizontally or vertically in the camera. The pick-up tubes (T) each have a mu-metal shielding (mu1) against magnetism. Each substantially vertically arranged pick-up tube (T2, T3) has an additional second mu-metal shielding (mu2, mu2'), which is absent for the horizontally arranged tube. The second shielding may be in the form of a single plate (mu2), overlapping the pick-up tube or two plates (mu2, mu2') arranged on both sides of the pick-up tube and overlapping the tube. Deflection errors, especially in the corners of the television pictures caused by magnetic fields, are reduced to acceptable values.
