Abstract: In a printed circuit board pair, each of the printed circuit boards having a contact region with contact elements, a contact-making system includes a first circuit board having three-dimensionally structured contact elements and a second circuit board also having three-dimensionally structured contact elements structured complementarily with respect to the contact elements of the first circuit board for positioning the two boards together. The contact elements of the first board reciprocally electrically contact the contact elements of the second board. The configuration ensures a high positioning accuracy of the two contact regions with respect to one another. A mask having cutouts for contact elements of the two boards can be provided. Such contact element positioning using the conductor track pattern and being independent of a contact-making housing has the advantage that the positioning accuracy is unaffected by tolerances between the conductor track pattern and the contact-making housing.

Abstract: A machine for washing and drying equipment and in particular impermeable sports equipment includes a housing with an opening through which pieces of equipment are placed radially into compartments of a partitioned carrier. The carrier is rotatably mounted in a fixed drum, which receives washing liquid and then hot air for washing and drying the pieces of equipment. Partitions in the carrier can be adjusted to form small or large compartments, which receive one or more pieces of equipment and hold the pieces separate from those in other compartments during washing and drying.

Abstract: At neutral or messenger wire for a power distribution system comprises a plastics tube supported by metal wires extending along the outside of the tube. Optical fibers arc located within the plastics tube and a coating is applied to the outside of the tube to enhance wear characteristics.

Abstract: A ground wire for a power transmission system has a plastic tube to carry a bundle optical fibers. The plastic tube is clad with a metal strip, preferably aluminium and is supported by a set of wire strands disposed about the tube.

Abstract: In order, in the context of making contact between two printed circuit boards (2, 4), to ensure a high positioning accuracy of their two contact regions (8) with respect to one another, the two contact regions (8) are three-dimensionally structured complementarily with respect to one another. A mask (12) having cutouts (14) for contact elements (10) of the two printed circuit boards (2, 4) is preferably provided. This positioning using the conductor track pattern and independently of a contact-making housing (26) has the advantage that the positioning accuracy is unaffected by tolerances between the conductor track pattern and the contact-making housing (26).
