Abstract: The present invention discloses a process for producing a high-quality insulation for conductors or conductor bundles of electrical machines by means of spray-sintering. Unlike in the prior art, it is possible to apply internal corona-discharge protection, insulation and external corona-discharge protection to conductors or conductor bundles in which, on account of a very low level of defects in the insulation and its inherent resistance to partial discharges, it is possible to dispense with the use of winding processes using glass/mica tapes. This eliminates the need to use complex special equipment and allows the throughput times to be shortened considerably.

Abstract: A Roebel bar (10) for an electrical machine comprises a plurality of essentially parallel, transposed conductor elements (11, 12, 13), which, lying over and/or next to one another, form a bar with an essentially rectangular cross section, which is surrounded on the outside by an insulation (19) and has between the insulation (19) and the conductor elements (11, 12, 13) means (14, 14?; 15, 15?; 17, 18) for forming an inner corona protection (ICP). In the case of such a Roebel bar, particularly effective inner corona protection is achieved by the fact that the means for inner corona protection comprise preformed, angled profiles (17, 18) of an electrically conducting material, which, running in the longitudinal direction of the Roebel bar (10), enclose the edges of the bar formed by the conductor elements (11, 12, 13), and to which the insulation (19) is applied.

Abstract: A process for producing insulations for electrical conductors by powder coating, which results in aging which is improved compared to glass-mica or casting-resin insulation, and a powder which is suitable for such a process. The powder is applied a number of times in succession, in the form of individual layers which follow one another, until a layer thickness of ?10 mm is reached, and each of the individual layers undergoes intermediate heat curing before the next individual layer is applied. The intermediate curing of each individual layer uses a curing time which corresponds to 2-10 times the gel time of the powder used. Finally, the entire insulation undergoes final curing. The result of an electrical life test carried out on various specimens insulated with epoxy-resin powder which contains fine filler.

The flexible tube according to the invention in this case comprises a glass fiber bundle which is encased by an inner glass cloth flexible tube. This glass cloth flexible tube is in turn externally coated with a polymer layer and is for its part surrounded by an outer glass cloth flexible tube. A matrix polymer is introduced into the inner glass cloth flexible tube and, after it has cured, the reinforced, pressure-resistant flexible tube can carry out its supporting and spacing function fully.

Abstract: In the English translation document, please add the paragraph at page 17 line 1, after the newly added ABSTRACT section heading, as follows: The invention relates to a method and a control device for requesting e-mail related information from an e-mail server, using a telephone. An entry via the telephone prompts a connection between the control device and the e-mail server to be established and also the transmission of the requested information from the e-mail server to the control device, e.g. a media gateway controller. The requested information is transmitted to the telephone and displayed on the latter by the control device. The invention permits access to e-mail messages using various types of telephone, such as e.g. an analog telephone, an ISDN telephone and a mobile telephone. The availability of information in the form of e-mail is thus increased. The invention also permits more flexible access to e-mail information in situations where an internet terminal is lacking.

Abstract: The process according to the invention discloses production of a high-quality insulation for conductors or conductor bundles. In this process, internal corona-discharge protection, insulation and external corona-discharge protection are all applied to the conductor or conductor bundle in successive steps by means of thermal spraying. The application thickness per spraying run is up to 0.2 mm, thus ensuring that the layer is free of defects and therefore avoiding partial discharges. Moreover, the ability to withstand thermal loads is considerably improved by the use of high-temperature plastics with fillers comprising inorganic materials as coating powder.
