  • Patent number: 4258616
    Abstract: An air outlet for the admission of conditioned air to rooms and other inhabited spaces includes an air box with an air outlet slot. The air outlet slot is longitudinally subdivided to form individual ducts each of which contains an independently adjustable air guide vane. Internally, the outlet slot may be variably obturated by three superimposed control slides, each of which has periodically occurring covering surfaces, the width of which corresponds to the width of an air outlet duct. The covering surfaces on each control slide are disposed at a distance corresponding to four duct widths. The air box contains thermostatically controlled actuators which are coupled to the control slides in such a way as to permit their relative longitudinal, i.e.
