Abstract: In a compact printed circuit board connector adapted to be mounted at a printed circuit board and intended to be soldered to the printed circuit board simultaneously with other electrical components in a heating oven by using a solder paste for soldering the components, a channel is provided which extends through the interior of the printed circuit board connector. The channel serves for circulating a flow of heated gas through the interior of the connector in order to quickly achieve the required soldering temperature at the soldering ends of the contact elements.

Abstract: For the mechanical coding of parts which can be joined together, it is proposed that the parts be connected to, in each case, one of two coding elements which belong together, the said coding elements being constructed as a one-piece coding module and being held together by means of web-like connections, and the connectable parts being divided up, after being joined together, into two coded releasable parts.

Abstract: In an electric plug connector comprising a carrier body (19) consisting of insulating material and a plurality of segments (2), inserted into the carrier body (19), with contacts (5) and terminals (4), the retention of the segments in the carrier body is to be improved. For this purpose an additional member (3) consisting of insulating material is provided which fixes the segment (2) in the carrier body (19).

Abstract: A device for taking samples from a catalyst block of a catalytic converter has a cutting tool rotatably mounted in a base plate that is surrounded by a collecting dish.

Abstract: A flexible tube construction is provided including a tube body and washer, each comprising a laminate having a metal barrier layer and a plastic layer which are adhered to each other by a butt connection. A plastic tube head is adhered to a synthetic plastic tube head having an opening through which the contents of the tube can be removed.
