Date Sep. 15, 1983.Machine tool having a jet turbine driving a rotatable spindle with a tool holder, said spindle is comprised in a spindle housing, said jet turbine consisting of a disc-shaped turbine rotor being closely enclosed by a turbine housing, said turbine rotor having peripherally arranged discrete recesses, each recess having a concave front actuation wall for the jet and one sidewardly arranged outlet opening which opens in the axial direction of the rotor, said housing having at least one inlet nozzle for the jet directed into the recesses and having at least one outlet opening for the spent jet medium. Known machine tools suffer under strong speed losses when the load increases or varies. This disadvantage results from a constant interference between spent air within the recesses and the working jet. Thus, the energy of the jet cannot be used with good efficiency. According to the present invention the energy of the jet can be used with better efficiency, since the inlet nozzle is directed towards the deepest section of the front concave actuation wall by impacting on this wall and since there is provided a guiding path and an additional expansion space below the jet which in combination produce a pumping effect for quickly disposing the spent jet medium. The expansion space is provided by the concave rear wall and the flat bottom of the recess. The guiding path is defined by the concave side wall together with the flat bottom and the concave rear wall.

Abstract: Two bypass lines (12, 14) are provided between the feed-water inlet line (5) into the economiser (6) of the steam generator and the outlet line (8) from the economiser. The line (12) more remote from the economiser contains a valve (13), preferably a modulating valve, while the bypass line (14) connected closer to the economiser contains a circulation pump (15). If the steam generator is operated in an upper load range from full load down to, for example, 70%, the valve (13) remains closed and the pump (15) is stationary. At lower loads, the pump (15) is allowed to deliver heated feed water from the outlet line (8) to the inlet line (15) and the valve (13) is kept more or less open. In this way, the load-dependent variation of the flue-gas temperature after the economiser is reduced and the operating conditions for a unit, fitted at this location, for catalytic flue-gas treatment are improved. <IMAGE>

Abstract: A method for the thermochemical surface treatment of workpieces in a reactive gas plasma is disclosed in which an appreciable reduction in the amount of reactive gas and energy used is achieved by working at gas pressures below 10 pascals (Pa). Particularly advantageous results are achieved with a low-voltage electrical arc discharge, which leads to an ionization of the gases used (about 50%) that is substantially higher than that, which is achieved with the methods described in the art 6 (approximately 1%). Surfaces, treated by such a conduct of the reaction, are distinguished by an increased hardness and better wear properties. The method of the invention moreover allows more numerous variation possibilities than do the methods described in the art and enables the conduct of the method to be adapted in a flexible manner to the specific requirements of the particular case. The inventive method permits a time sequence of the several treatment steps with different reactive gases or gas mixtures and thus a combination of different foreign elements in the treated substrate surface.

IPC: G08B13/24
Filed: 1988-02-10
Abstract: This invention relates to a method and apparatus for contactless identification of a label which incorporates passive resonators, with the aid of high-frequency magnetic fields. One significant feature of the inventive method is that large quantities of information of practical interest can be accommodated, despite the fact that the resonators can be given a Q-value which is so low as to enable the resonators to be given the form, e.g., of printed circuits mounted on plastic foil. The frequency stability requirement of the resonators is also low, which enables the labels to be produced very cheaply with the aid of suitable manufacturing techniques herefor, and also enables labels to be produced for one-time use only. The method is based on a high-frequency signal which is scanned over a broad frequency band and modulated at the same time, with appropriate detection, the modulation results in a response of narrower bandwidths than that obtained with earlier known methods, therewith enabling more resonators to be accommodated and to be separated within a given frequency range. The inventive apparatus with which the method is put into effect includes, inter alia, means for controlling the scan, modulation and amplification over the frequency band. One significant feature of the inventive apparatus resides in the provision of a coil arrangement which affords a comparatively large range while, at the same time, satisfying government regulations concerning maximum radiation powers.
