Abstract: A pressing table has a main pressing surface element and a pivotable additional pressing table surface element, and a blower capable of applying suction or blowing action selectively to one or other of the pressing table surface portions. Change over from suction to blowing is achieved by the action of the blower fan discharge air in response to triggering by a solenoid thruster, and the blowing action is held on by the airstream until the blower fan stops. Selection of the additional pressing table surface element for the blowing or suction action is automatic in response to pivoting of the additional element from a rest position to an operative position.

Abstract: A press table comprising a suction and blowing unit is disclosed. The suction and blower unit is adapted for direct connection with the lower side of the press table, thereby achieving optimized changeover speed from suction to blowing and vice versa. The press table comprises one or two auxiliary press table members and control means for automatically bringing the auxiliary press table members into communication with the suction and blower unit when they are used, simultaneously disconnecting the main press table from the unit.

Abstract: A monitoring device for monitoring incandescent lamps, especially in motor vehicles, is provided. A measuring resistor is connected in series with an incandescent lamp to be monitored. Means for monitoring the voltage drop at the measuring resistor are provided. The monitoring means comprises an operational amplifier to one input of which the connection between the measuring resistor and the incandescent lamp is connected and to the other input of which a voltage divider is connected which is mounted in parallel with the measuring resistor and the incandescent lamp. The voltage divider is formed of ohmic resistors, and the output of the operational amplifier controls an indicator means for generating an indication signal upon missing or excessively low voltage drop at the measuring resistor.
