摘要:
Method of humidifying a cold air stream in which movable surfaces of low heat conductivity mounted in a housing of low heat conductivity are continuously wet by a thin cohesive film of water obtained by dipping the moving surfaces in a water bath maintained in constant level at a constant temperature above the temperature of the air then the wet moving surfaces being exposed to the air stream to be humidified.
摘要:
An ironing machine with a computer-assisted control device for the advancing pressure and the pressing time between an upper and a lower shaping board (10, 16) which are movable relative to one another both vertically and horizontally, the ironing machine has a differential-pressure regulating device (1 to 6, 11) which, during the computer-controlled application of pressure to the article to be ironed, takes into account the dead weight of the movable shaping board, as a rule the upper shaping board (10). A substantially higher ironing quality, especially where sensitive textiles are concerned, can be achieved by the invention, because the ironing pressure can be preselected reproducibly within very fine steps.
