摘要:
For drying coatings and varnish, an energy transmitter (1) is provided comprising two transmitter surface elements (10) as antennas, with the transmitter elements (10) having a glass carrier plate (11) bearing a radiation layer (13) on a rear glass surface (12) whose opposite free front glass surface (17) is directed towards the surface of a component (3) to be dried. Spaced apart and parallel to the rear glass surface (12), a surface reflector (20) of a metal is positioned, with a corresponding radiation layer (13) for emitting electromagnetic radiation in a frequency band that covers the characteristic natural frequencies in ultrared of an object to be dried, the radiation layer (13) being excitable by means of a control device (16) to emit a frequency band so that natural frequencies of the object to be dried are excitable in resonance.
摘要:
A first partial heating system having a first heat source with an integrated heat source heat exchanger and heat transfer devices spaced from the heat source as a radiator with heat transfer outside surfaces and flow lines and return lines between the heat source heat exchanger and the heat transfer devices containing a flowable heat transport medium. A second partial heating system having a second heat source. A heat control system with a temperature regulator and switching unit for controlling both partial heating systems for individual operation or joint operation. The second partial heating system is a radiation heating system having a radiation surface coating capable of electrical activation which is applied to the heat transfer outside surfaces of the radiator as a radiation surface of the second partial heating system.
摘要:
A method of sensing the axle geometry, in particular the toe-in, camber and caster, on motor vehicles with independent wheel suspensions. The inclination of certain links of the wheel suspensions is measured in at least one arbitrary motor-vehicle position, or the inclination measurements are carried out in the case of certain links of the wheel suspensions and one specific location of the vehicle body in at least one arbitrary motor-vehicle position. The measured values sensed are sent via a data line or wirelessly to a computer and either compared with vehicle-type-specific setpoint values or setpoint value ranges adapted in the computer to the currently applicable motor-vehicle position or are converted in the computer to a neutral motor-vehicle position and compared with the vehicle-type-specific setpoint values or setpoint value ranges based on a neutral motor-vehicle position. With the aid of the deviations between the measured values and the corresponding setpoint values or setpoint value ranges determined during comparison, a measuring or checking record of the axle geometry and/or a set of machine-processable alignment data is produced.
