Abstract: The wall contains elongate members (1) which are connected to one another by means of junction pieces (2). Each member (1) has a tubular portion (7) and at least one endpiece (10). That part (12) of the endpiece (10) located outside the portion (7) is equipped with a gripping wheel (30) for making and breaking the connection between the elongate member (1) and the junction piece (2). The junction piece (2) contains a baseplate (40) with receiving parts (41) for the endpiece (10) of the member (1) and a device (65) which makes it possible to fasten further wall components (3,9,71) to the junction pieces (2). The receiving part (41) comprises cheeks (42,43), between which extends an axle (45). A slot in the gripping wheel (30) surrounds this axle (45) when the endpiece (10) is located in the receiving part (41). The baseplate (40) is equipped with orifices (83) which allow the connection of wall plates (3,4) and hinges (90).

Abstract: Windings for electrical machines and appliances, which windings remain mechanically stable even when the operational temperature is exceeded for a short period and ensure good heat transfer between the winding and the iron of the magnet core without additional impregnation, are produced by lining the slots in the magnet core with a slot liner coated on at least the side facing the magnet core with at least one B-state resin which is completely non-tacky at room temperature but is capable of being cured and becomes tacky at the temperatures employed in the curing of the thermosetting adhesive layer of the adhesive varnished wire used, by making the winding from adhesive varnished wire with a thermosetting adhesive layer and curing by heating the coating on the slot liner and the adhesive layer on the adhesive varnished wire.

Abstract: A flexible electrical power cable is described. The cable comprises a flexible metallic conductor and a plurality of alternately wrapped insulating layers comprising (1) at least two spirally wound layers of a tape made from mica paper and from a sheet of fibers which are resistant to temperatures up to at least 300.degree. C, the tape being impregnated with an adhesive silicon resin and (2) a layer of temperature-resistant plastic film or sheeting which is stable to at least 300.degree. C.
