Abstract: In a process for insertion of wire (30) in the form of a field coil (56) between the pole horns (38, 40) and the stator wall (36) of a double-pole stator (14) of an electric motor, the stator (14) consists of two stator halves (12a, b) and the wire (30) to form the coil (56) is inserted by way of a winding arm (16) rotating about a rotation axis (y) lying perpendicular to the stator axis (x), where during the winding process, for temporary formation of an enlarged insert groove (34, 35) for the wire (30), a winding accessory (32) is laid against the outer edge of the stator (14) and the free ends of the pole horns (38, 40) are covered with a wire guide sleeve (42). The process allows the winding of stators in which the pole horns largely cover the rotor external diameter of collector motors, leading to a higher motor power.

Abstract: Process for manufacturing cold formed shaped forms of packaging having at least one recess from a metal-plastic laminate. Examples of such shaped forms of packaging are the base parts of push-through packs or blister packs. The process is such that the laminate is held between a retaining tool and a die. The die 1 exhibits at least one opening and a stamp is driven into the die opening causing the laminate to be shape-formed into a packaging, correspondingly exhibiting one or more recesses. The die and the retaining tool exhibit facing edge regions and the die, within the edge region, exhibits a shoulder region that surrounds the die opening or openings. The surface of the shoulder region lies 0.

Abstract: The present invention concerns the improvement of the supercurrent carrying capabilities, i.e. the increase of critical current densities, of bicrystalline or polycrystalline superconductor structures, especially of high-Tc superconductors. By providing an appropriate predetermined dopant profile across the superconductor structure, in particular within or in the vicinity of the grain boundaries, the space-charge layers at the grain boundaries are reduced and thereby the current transport properties of the superconductor significantly improved. Simultaneously, the influence of magnetic fields on the critical current densities is significantly reduced, which in turn enhances the overall supercurrent carrying capabilities while keeping the supercurrent transport properties of the grains at good values.

Abstract: Hydrocarbon contaminants in drill cuttings generated in an oil drilling operation are removed by mixing the drill cuttings with an agglomerant to produce a pre-treatment mixture; heating to vaporize the hydrocarbon contaminants under a condition in which vapor entrainable particles of the drill cuttings are agglomerated by the agglomerant, and caking of drill cuttings is inhibited; drill cuttings having a reduced content of the contaminant are removed, and vaporized hydrocarbons having a reduced content of vapor entrainable particles are recovered. In this way, the particulate content of vapors escaping from the drill cuttings is reduced.

Abstract: An instrumented capsule for material irradiation tests in research reactors. The instrumented capsule performs an optimum material irradiation test under a testing environment similar to the operational environment of a real reactor. The capsule minimizes the influence of flow-induced vibration caused by forced-circulation-type coolant flow in a research reactor, and overcomes the problems experienced in the conventional breakable parts of instrumented capsules which may be broken during the process of loading/unloading the capsules in vertical irradiation holes of reactor pools. The instrumented capsule includes a capsule main body installed in the vertical irradiation hole. The capsule main body consists of a shell and several instruments, such as thermocouples, dosimeters, a vacuum control pipe, and heaters housed in the shell.

Abstract: Hot-air device with a heating element situated in a stream of air, with a carrier consisting of temperature-resistant material and heating wires located in the air channels, and with at least one metal mount for the carrier, wherein the temperature-resistant material of the carrier comes into at least partial electrical contact with the metal mount, and is connected to a device for interrupting the heating circuit, which, during heating, interrupts the heating circuit when a threshold value is reached owing to the measuring current discharged over the insulating material and the contact element. The direct and very quick measuring principle enables a simple and inexpensive protection of the heating element, as well as control and regulation without additional sensors. It is possible to control or regulate the hot-air temperature of the hot-air device via the measuring current.
