Title: Hollow spindle stop - has tension pressure compensation device to absorb residual movement of hollow spindle
Inventor: SPRINGER REINER
IPC: B23Q16/00
Filed: 1990-11-27
Abstract: With rotary machines, in whch tension occurs through an axial movement of the hollow spindle in the direction of the chuck, there is a displacement of the stop which moves with the clamping union with the hollow spindle. The workpiece in the machine moves along until contact occurs with the clamping jaws, which stops the forward movement of the workpiece. As machining requires very high pressure there is a residual movement of the hollow spindle which is absorbed by a pressure spring (2) forming part of a tension pressure compensation device. This device consists of a body (1), a pressure spring (2), a bolt (3), a shaft sealing ring (4), a clamp plate (5), and a stop shaft (6). USE - In rotary machines, partic. lathes, as a hollow spindle stop with tension pressure compensation.

Title: Reduction of noise transmission between machine parts - by using projections formed on joint faces
Inventor: ALBENBERGER JOHANN
IPC: G10K11/16
Filed: 1991-01-31
Abstract: The noise transmitted between two metal parts of a machine, is reduced by forming projection (9) on one of the two abutting faces of the two parts.

This method is particularly applicable to rotating machines, such as turbo-superchargers, where noise may be generated as a result of the imbalance of rotating parts. The projections are spaced at varying distances from each other and only a small number of projections are formed on any one face. USE/ADVANTAGE - Reduction of noise transmission through machine parts.

Abstract: A changeover switch (8) connected to the input of a digital memory (9) is so controllable that during the receipt of the adjusted frequency the digital audio signals are fed into the memory, and then for further processing (10), and during the receipt of the other frequency output, signals from the memory are fed into the memory again, and on for further processing (10). Between the unaltered audio signal and the delayed audio signal a fade-out takes place. For Fourier analysis, a digital signal processor and for storage of the audio signal sections print-read memories are provided. A digital filter in the digital signal processor scans the spectrum of the audio signal by alteration of the filter coefficients according to the energy-richest components.     One of the delay devices (11, 12) is provided with a tapping device, which is connected to switches, via which audio signal sections reach a print-read memory.

Title: Quantitative and selective ion measurement - uses an adsorption medium which is washed with a reagent for chromatography and photometer detection
Inventor: SCHAEFER HELWIG DIPL CHEM DR
IPC: G01N30/08
Filed: 1991-07-31
Abstract: To give a quantitative selective count of one or more ions present in metallic or cpd. types of the same metal as a soln. for analysis, the soln. is passed through an absorption medium which only absorbs those ions to be detected. The ions are washed from the absorption medium by a flow medium which contains a reagent which, by chemical reaction, forms a specific recognisable compound. The wash is treated by chromatography to separate the materials dissolved in its content, for the chromatographed wash to be examined by a detector. The concn. of the ions is determined by applying the detected measurements to a characteristic chemo-physical value. Pref. before the absorption medium is washed, the unabsorbed analysis soln. is washed clear with deionised water. The recognisable cpd. is a characteristic coloured cpd. for a photo-meter detector to give a measured value with a characteristic extinction coefft. for the cpd. An acid rhodanide soln. is pref. for washing ions from the absorption medium. The photometer detector works with characteristic wavelengths for Cu and/or ferrous rhodanide complexes. An acid ion exchanger is used as the absorption medium, or it is a semiconductor of Si or a fixed Si cpd. The pref. reagent is PAR (4-(2-pyridylazo) resorcin). The ion concn. is determined by comparison with the extinction coefft. of various concd. calibrating solns. USE/ADVANTAGE - The technique is for the analsyis of ions in the semiconductor industry, where disruptive ions could affect the material performance. The process gives a quantitative and selective measurement of ions in solns. with a concn. of 10 power (-6) g/litre.
