Abstract: The connection of the circuit board (7) of the appliance to connector blocks (10) is obtained by inserting and soldering holders (11) having connecting terminals (16) to the circuit board, connector blocks (10) being loosely attached to said connecting terminals (16). The mutual mechanical and electric connection is obtained by inserting the assembly into a case which secures the connector blocks to the circuit board, on one hand, and by fastening clamps which establish a connection of the connecting terminals (16) to connected conductors. The assembly of the appliance is particularly rational since the holders (11) with the connecting terminals are placed on the circuit board together with the remaining, non-represented components and are soldered thereto in common, the connector blocks (10) being simply slid on. The assembly is thus well suited for automation. The connector blocks abut to the edges of the circuit board (7), thus allowing a good space utilization and a compact construction.

Abstract: The spray unit lies downstream, in-line with an extrusion press and serves to cool metallic sections in particular sections of aluminum or an aluminum alloy from all sides. The cooling medium emerges from spray nozzles program-controlled in the direction of the section. The distance, the cross-section distribution and the direction of the spray nozzles are adapted specific to the geometrical shape and distribution of mass in the section. The optimum parameters are determined and stored in the unit processor. The spray nozzles are arranged in nozzle beams running in the direction of the extruded section. The nozzle beams comprise at least one longitudinal water channel and two longitudinal air channels, whereby cross-intersecting channels branch off from the water channels to the spray nozzles and the air channels terminate in air gaps which are directed towards the nozzle outlets.
