Abstract: A plurality of drivers (14) are attached to an endless rotating belt (13). In the traversing region, two strands (15, 16) of the belt (13) are movable between two respective guide rollers (4, 5; 6,7) at least approximately parallel and in opposite directions. Outside the traversing region, the belt (13) forms, on each of the two sides, a reversing loop (17, 18) which is guided over a deflecting roller (8, 9). According to the invention, the guide rollers (4, 5) and the guide rollers (6, 7) are so arranged next to one another that they confront one another with a side face. The deflecting rollers (8, 9) are arranged askew to the guide rollers (4, 5; 6, 7), so that, in the region of the reversing loops (17, 18), the belt (13) is twisted in the manner of a three-dimensional belt drive. This ensures that the constructional-length/traversing-stroke ratio is more advantageous than in known belt traversing devices which are equipped with a single belt. The device is especially suitable for winding appliances in which a plurality of bobbins are arranged in one or more rows next to one another on one axis.

Abstract: A method and an apparatus for automatically detecting the temperature of metallic rotatable bodies (8) without establishing any contact therewith. Electromagnetic energy is radiated by means of a transducer (B1), i.e. a solenoid in which an alternate current is passed, towards the surface of the metallic body (8) where induced currents are generated. The thickness of material penetrated by said currents is inversely proportional to the frequency of the solenoid current. The impedance variations in the material are detected by said solenoid (B1), and the relative signal is supplied to a computer (12) discriminating the signal relative to a resistivity variation of the same material, thus deriving the temperature of the body (8).

Abstract: Ein Verfahren dient zur Aufnahme von Spinresonanzspektren von Proben mit mindestens drei Gruppen von Spins. Eine erste Gruppe ist mit einer zweiten Gruppe gekoppelt, während eine dritte Gruppe mit der zweiten Gruppe ungekoppelt ist, jedoch eine spektrale Lage, z.B. eine chemische Verschiebung aufweist, die nur mit derjenigen der ersten Gruppe im wesentlichen übereinstimmt. Zur alleinigen Darstellung des Signals der ersten Gruppe wird das Signal der dritten Gruppe unterdrückt. In an sich bekannter Weise wird eine Impulsfolge von drei Hochfrequenz-Impulsen (10, 13, 22) auf die Probe eingestrahlt. Der zweite Impuls (13) wird derart eingestellt, daß die Magnetisierung der Spins der ersten Gruppe mittels Polarisationstransfer auf die Spins der zweiten Gruppe übertragen wird. Sodann wird auf die Probe ein für die Spins der zweiten Gruppe dephasierender, erster Gradienten-Magnetfeld-Impuls (17, 23) ausgeübt. Der dritte Hochfrequenz-Impuls (22) wird derart eingestellt, daß die Magnetisierung der Spins der zweiten Gruppe mittels Polarisationsrücktransfer wieder auf die Spins der ersten Gruppe übertragen wird, die schließlich einem zweiten, für die Spins der ersten Gruppe (A) rephasierenden Gradienten-Magnetfeld-Impuls (23) ausgesetzt werden.

Abstract: An electrode for engraving electric spark machining which is produced by using a mixture of gypsum hemihydrate powder serving as both a principal material and a binder with a conductive metal powder as a filler, transferring, shaping and hardening the mixture into a desired shape to form electrode material and plating the electrode with the conductive metal. Gypsum hemihydrate powder, gypsum dihydrate powder of less than 1 vol % on the basis of the former and the conductive metal powder are kneaded in a vacuum. Water is added to the kneaded matter, which is again kneaded in a vacuum, poured into a mold to which a predetermined shape is transferred, shaped and hardened by hydration to obtain an electrode material. Then the electrode material is dried and plated with the conductive metal so as to reinforce electrical connection with the metal powder. Since the electrode is made of gypsum as the principal material, even an electrode for electric spark machining to which a precise and complicated shape is transferred can be produced easily, economically, and precisely by the use of a simple mold of, e.g. a silicone rubber, and hence it is particularly suitable for producing dental crowns one by one. Furthermore, gypsum hemihydrate as the principal body of the electrode material and the conductive metal film increase the strength of the electrode by virtue of their synergistic effect. The present invention makes possible machining of a hard material such as titanium for which precise electric spark machining at a desired speed has been difficult by the use of a conventional electrode subjected to impregnation treatment of a conductive solution in which graphite or the like is dispersed in place of plating treatment.

Abstract: An arrangement for adjusting a carriage of a machine tool by means of a carriage adjusting motor has a stationary spindle (1) on which are mounted a spindle nut connected to the carriage and an overload coupling (4, 8, 11, 12, 13) to protect the adjusting arragement. The stationary spindle is secured by means of the overload coupling to a stationary part of the machine tool so as to remain fixed during rotation and can be rotated only after the set limit torque of the overload coupling is exceeded. According to the invention, the masses moved are less than in the prior art. In addition, the dynamic component of the masses to be moved is less in the event of overloading. A further essential point is that the overload coupling is backlash free and has a high torsional rigidity, i.e. it retains maximum torsional rigidity until the set torque limit is reached.
