Patent EP-1474683-B9 (EP)
Inventor: BENDTSEN ANDERS BROE
IPC: G01N15/04

Granted: 2010-06-23
Abstract: The content of casein in milk is determined by two measurements of infrared absorbance in a milk sample by infrared spectrometry before and after a separation of the casein. The casein content is calculated by use of absorbance data recorded during the two absorbance measurements. The new method is considerable faster than the known wet-chemical methods, such as the normal wet chemical reference method for casein determination in milk using a Kjeldahl nitrogen determination of the milk sample, then a coagulation of the milk, and finally a Kjeldahl nitrogen determination of the filtrate. Further the new method provides a more reliable accuracy than the know determination using a single infrared analysis of a milk sample.

Title: Production of yogurt
Inventor: GIUSEPPIN MARCO LUIGI FEDERICO
IPC: C12P1/04
Filed: 2015-05-08
Abstract: The present invention is in the field of fermentation, and pertains to a method for preparing yogurt by fermentation, comprising the steps of providing a fermentation starter culture comprising a selected microorganism in a suitable culture medium, adding a potato protein protease inhibitor to the culture medium, culturing the microorganism, and harvesting the yogurt. This method has the advantage that the lag time of fermentation can be reduced by the addition of relatively low amounts of potato protein protease inhibitor. It has the additional advantage that the potato protein protease inhibitor allows for application of the present method over a wide pH range and wide temperature range including pasteurization, is filter sterilizable and that potato protease inhibitor protein is non-allergenic.

Patent DE-3516913-C1 (DE)
Inventor: KUPFER KARL-HEINZ
IPC: H03H7/12
Filed: 1985-05-10
Granted: 1986-10-02
Abstract: The invention relates to a circuit arrangement for a video playback apparatus, comprising a band-pass filter arranged after the video heads in the luminance-signal playback channel. The frequency characteristic of the band-pass filter is variable in order to influence the amplitude characteristic of the FM sideband spectrum. The band-pass filter is followed by an FM demodulator and a crispening circuit. The frequency characteristic of the band-pass filter is controlled automatically depending on the level of the high-frequency components in the demodulated luminance signal in that the frequency characteristic of the band-pass filter is varied by means of a pre-emphasised luminance signal taken from the crispening circuit in such a way that a luminance signal whose FM spectrum in substantially amplitude-symmetrical relative to the FM carrier frequency is produced on the output of the band-pass filter.

Title: Method for locating leaks in pipelines
Inventor: FROMMHOLD WERNER DIPL-ING
IPC: G01M3/24
Filed: 1986-03-10
Granted: 1987-08-13
Abstract: In the leak-locating method according to the invention, which employs cross-correlation analysis, the 2-channel FFT analyzer is used to measure the difference in propagation time. The cross-power spectrum is firstly subjected to equalisation, weighted with a suitable frequency weighting, if necessary, and subsequently transformed back into the time range. As a result, instead of the known cross-correlation function a different time function with optimum resolving power is obtained, and this permits the determination of leaks with higher accuracy and over a larger measurement range. The subsequent equalisation of the cross-power spectrum can be performed in a much finer fashion than could be obtained using conventional filters 3 in accordance with Figure 1. The method can be implemented without additional outlay on equipment using conventional FFT analyzers. Since the method can run automatically, the interposition of the equalisation requires no additional time outlay in practical use.
