Patent EP-0458291-A2 (EP)
Inventor: POPP GERHARD
IPC: B27G19/10
Filed: 1991-05-22
Abstract: The machine has a longitudinal-profiling unit with at least one profiling tool and a retaining arrangement having a retaining means (18). The latter is laid, upon withdrawal of the profiling tool from the workpiece, against the withdrawal end thereof. The retaining means (18) is provided with two retaining parts (36 and 37), of which one retaining part (36) is displaceable in the conveying direction of the workpiece relative to the other retaining part (37). This ensures that the retaining means (18) lies, over its entire width, against the workpiece even where there are tolerances in the profile. As a result, the workpiece is prevented from being torn out upon withdrawal of the profiling tool from the workpiece. The retaining means (18) can be laid against previously profiled but also, owing to the displaceable retaining part (36), against unprofiled outer sides of the workpieces to be worked, in order to retain them. <IMAGE>

Abstract: In order to decrease errors in spectral measurement, the data measured at sampling wavelength intervals smaller than the wavelength sampling intervals are changed to data of wavelength sampling interval of spectral effective curve. 
     If the wavelength half-bandwidths to be measured are different from the wavelength sampling intervals, the spectral data at wavelengths in correspondence with the wavelength sampling intervals are obtained with interpolation. 
     In a spectroradiometer, wavelength scale is calibrated with use of a plurality of line spectra of specified wavelengths, and the photoelectric outputs are integrated with use of the addresses of elements as a weight factor.

Abstract: A device is used to control flashing of a camera (1) having an electronic flash (101) for performing main flashing for photography and preliminary flashing for obtaining information used to limit the quantity of light for the main flashing in accordance with a TTL scheme. The device includes a plurality of photoelectric converting means for receiving light beams corresponding to a plurality of photometric areas (PD11-PD51) constituting a field of view during the preliminary flashing and main flashing, converting the light beams into photocurrents, respectively, and outputting electric signals corresponding to the photocurrents, respectively, and a logarithmic transforming means for logarithmically transforming outputs from the plurality of photoelectric converting means. A peak holding means detects outputs from the logarithmic transforming means which correspond to maximum values of the outputs from the plurality of photoelectric converting means and holds the outputs from the logarithmic transforming means. A field reflection distribution is obtained on the basis of outputs from the peak holding means, and weighting coefficients of the photometric areas during the main flashing are determined on the basis of the field reflection distribution. The outputs from the plurality of photoelectric converting means are weighted in accordance with the weighting coefficients determined by an arithmetic means, the weighted outputs are added, and the quantity of light during the main flashing is limited on the basis of the obtained sum.

Abstract: In a cross polarization interference canceller for use in digital radio communications, a signal processing circuit (20) monitors whether numbers of word sync signals and error pulses obtained in error correction decoding exceed specified values, and outputs reset signal RS1 when an abnormality is detected. A signal level detection circuit (21) outputs reset signal RS2 when it is detected that a level of a different polarization side baseband signal from a demodulator is lower than specified. A logical sum RS3 of reset signals RS1 and RS2 is supplied to a cross polarization interference canceller (18). When the word is not synchronized or the number of error pulses generated in error correcting decoding exceeds the specified value, the self-polarization side can be protected from unnecessary interference and disturbance and the self-polarization side data can be protected from disturbance even though an abrupt abnormality occurs in different polarization signals.

Abstract: The invention relates to a process for the oxidation of a cycloalkanone containing 6-12 carbon atoms to the corresponding lactone in the presence of a benzaldehyde with the aid of an oxygen-containing gas, the benzoic acid that is formed in the oxidation being hydrogenated to benzaldehyde and the benzaldehyde thus obtained being used again in the oxidation of cycloalkanone. 
     A catalyst that is very suitable for the conversion of a benzoic acid into the corresponding benzaldehyde can be obtained via coprecipitation of a manganese salt, a salt from which an acid support is formed at a pH between 7 and 10 in the presence of a zinc salt and optionally a copper salt, through calcination, after precipitation, at a temperature of between 300 and 700°C and then reduction with the aid of a hydrogen-containing gas mixture.
