Embodiments of the invention provide for conical magnets for rotors in electrodynamic machines, methods to design the same, and rotor-stator structures for electrodynamic machines. In various embodiments, a rotor-stator structure for electrodynamic machine can include field pole members and conical magnets. According to at least some embodiments, one or more of the conical magnets can include a magnetic region configured to confront one or more air gaps. The magnetic region can be substantially coextensive with one or more acute angles to the axis of rotation. The magnetic region can also include a surface positioned at multiple radial distances from the axis of rotation in a plane perpendicular to the axis of rotation.

A method, apparatus and system producing for electrodynamic machinery are disclosed. In one embodiment, an integrated stator-housing structure for constructing electrodynamic machines includes one or more field pole members. Each field pole member can have a first pole face and a second pole face. Also, the members each can have a field pole core being configured to produce a flux path in a direction from the first pole face to the second pole face. In one embodiment, the integrated stator-housing structure can also include a housing structure configured to support the one or more field pole members. The housing structure is configured to mate with one or more other housing structures to form an enclosure of an electrodynamic machine. In another embodiment, the housing structure is composed of potting compound formed with the one or more field pole members in, for example, a mold. In this case, the integrated stator-housing structure includes the potting compound and the field pole members. In a specific embodiment, the flux path is straight from the first pole face to the second pole face.

An arrangement for connecting a tubular first component to a second component, in particular for connecting a tensioning tube to an A-pillar of a vehicle body, has a first structural element which forms a receptacle for a screw element and is arranged at an end of the first component that faces the second component, and a second structural element which is secured in such a manner at that end of the first component which faces the second component that the first structural element is held between the first component and the second structural element, and the screw element is held by the second structural element in the first structural element in loss-proof fashion, the screw element being movable in the first structural element, at least in a direction transversely with respect to a longitudinal axis of the first component, for compensation of tolerances in the connection of the first component to the second component. Furthermore, a method for producing an arrangement of this type is described.

For drying organic solid materials, such as brown coals, the solid materials are, particularly for the purpose of immediately subsequent briquetting or refinement or gasification, respectively, preheated and introduced into an atmosphere of saturated steam at super-atmospheric pressure and increased temperature. After such a first drying stage (1, 2) operated with saturated steam, the process water formed in this drying stage is separated and the solid materials are at least partially pressure-released and subsequently further dried within an atmosphere of superheated steam at a temperature of at least 200.degree. C. of this steam atmosphere. The steam of this further drying stage (7) is passed along a closed circuit via heat exchangers (10, 11) and brought to or maintained at the required temperature. A portion of the steam passed along a closed circuit, that portion approximately corresponding to the amount of steam having its origin in the water content of the solid materials, is tapped via conduit (12) and used for preheating purposes (FIG. 1).

Coating formulations having improved adhesion are described which are especially suitable as primer for top coats of fluorocarbon polymers, which comprise (a) a copolymer of tetrafluoroethylene units, units of a perfluoroalkylvinyl ether and optionally units of hexafluoropropylene or vinylidene fluoride, (b) optionally dispersed polytetrafluoroethylene particles in addition, (c) a mixture of lithium hydroxide and suspended fine-particle pyrogenic SiO.sub.2, and (d) water as liquid carrier. The coating formulations are applied according to known methods to substrates such as metals, glass or ceramic surfaces. They may be used as single-layer systems without top coat, or as primer, the top coat being applicable immediately after a short-time drying only. Application fields are the coating of household equipment or technical apparatus, where a high-grade adhesion onto the substrate, combined with anti-adhesive properties and a smooth surface are obtained.

The invention relates to a method for separating impurities out of slags, dusts, minerals, preparation residues of minerals or of recyclings or remaining substances, subsequently called feed stock. In order to save energy and reduce costs, the inventive method is characterized by the combination of the following features: melting the feed stock containing the impurities; forming a copper melt; bring the feed stock into contact with the copper melt while adding reducing agents, preferably coke and/or coal; vaporizing, if required, existing volatile compounds such as metal chlorides; reducing metals of the feed stock more noble than copper in the copper melt, and; forming a slag with constituents of the feed stock to be purified that is less noble than copper.

A method for constructing a three-dimensional laminated shape includes selecting a first lamination strip from a plurality of lamination strips with different widths assembled on a spool. The first lamination strip is stacked on a stacking device and is cut at a first lamination length. A second lamination strip is selected from the spool. The second lamination strip is stacked and cut at a second lamination length different than the first lamination length. The process is repeated to construct a three-dimensional laminated shape of an electrodynamic device. In another embodiment, a computer readable storage medium includes executable instructions to collect design information characterizing a three-dimensional laminated shape and compute lamination parameters based on the design information. The computer readable storage medium further includes executable instructions to direct a plurality of components to construct a three-dimensional laminated shape of an electrodynamic device based on the lamination parameters. The three-dimensional laminated shape comprises a plurality of lamination strips of different lamination widths and different lamination lengths.

A self-closing cap for the filler neck of an oil pan is provided which allows the oil pan of an engine to be filled without the necessity of removing the cap. The cap comprises a lower body having a flat inner bottom surface with a passage in it, and a spring-loaded closing plate that likewise includes an opening. The closing plate is slidably movable over the flat inner bottom surface o the lower body against the force of the spring by means of a handle such that its opening is alignable with the opening in the bottom surface of the lower body to form an oil receiving passage.
