摘要:
The invention relates to an apparatus and to a method for removing thickenings in layers which are produced transversely to the direction of travel of the web after the coating of continuously moving webs with liquids whereby the coated web is deflected by a web guide element and two air jets pointing towards each other are directed to a small angle .alpha. towards the layer of the web from below the deflecting point as air blades which are actuated when thickenings appear in the layer and which scrape off the particles of the thickening and blow them into a vacuum tank which is sprinkled all over with water and the water and particles are supplied to a vacuum generating device which, in turn, is evacuated by a jet suction device without interrupting the vacuum.

The invention relates to a device (1) for modifying an AC voltage, wherein the device (1) comprises an input (1) for connecting to an AC voltage source and an output (3) for connecting to a load circuit. The device (1) comprises an interrupter (15) that is designed such that, within at least one time window (35), the output (3) can be disconnected from the AC voltage source, wherein the time window (35) has a time delay (36) from the zero crossing (40) of the voltage of the AC voltage source. At the output (3), the device comprises a terminator (20) that is designed, in particular together with the interrupter (15), such that the voltage at the output (3) of the device (1) has a predefined or predefinable value (37) in the time window (35). Furthermore, the device (1) comprises a pulse shape generator (8) for generating a predetermined or predeterminable pulse shape, and control means (4) that actuate the terminator (20) and the interrupter (15) such that the voltage curve at the output (3) of the device (1) can be modified according to the pulse shape predetermined by the pulse shape generator (8).
摘要:
A communication system comprising at least one electric appliance (2, 17, 18, 19, 20) and a server (1, 21). The appliance (2, 17, 18, 19, 20) is linked to the server (1, 21), relevant data of the appliance (2, 17, 18, 19, 20) is reproduced in the server (1, 21) and the latter can be connected to a call center (5) via the Internet. When a request is made, the call center can access the server (1, 21) or the appliance (2, 17, 18, 19, 20) and the desired appliance (2, 17, 18, 19, 20) function or status can be achieved by the remote action of the center.
摘要:
A valve controlled fluid power actuator arrangement having a fluid power valve arrangement (61) controlled by an electronic control means (63 through 65) being connected by means of at least one plastic fluid power line (11) with at least one actuator (62). In the plastic line (61) electrical line strands and/or light guides are integrated for the transmission of sensor signals. The at least one plastic line (11) is connected with the respective actuator (62) with the aid of a connection member (10) having a connection cable (29) with at least one sensor (30) in or on the actuator (62). Accordingly in the case of a valve arrangement separate from the actuators a rapid and simple fluid power and electrical or, respectively, optical assembly may take place.
摘要:
A switchgear cabinet with a central control device for monitoring and controlling built-in units and/or attached units of the switchgear cabinet in a predetermined manner. A simple adaptation to various requirements is offered here, because central control device has components of a personal computer, through which it is programmable and by means of which monitoring, control and/or regulation takes place in accordance with predetermined programs.
