Abstract: The invention relates to a method for testing fuel element tubes by ultrasonic energy. For testing, each tube becomes disposed in the space between a transmit transducer and a receive transducer. The echo signals falling within a predetermined time interval are evaluated. Since the distance between the transducers may vary as the transducers move through the space between fuel element tubes, the transmitted signal reaching the receive transducer without passing through the tube may be confused with the revolving echo signal. Therefore, this invention discloses an arrangement for cyclically controlling the setting of the time gate before each such tube is in position between the transducers. To this end, the ultrasonic transit time of signals between the transmit transducer and the receive transducer is measured in the gap between the last tested tube and the next to be tested tube. A constant value is subtracted from the measured transit time value and this constant value is selected so that the transmitted signal received during the transit time measurement falls just outside the gated time interval.

Abstract: The invention is concerned with a process of removing cadmium from acid, especially P2O5-containing solutions by liquid/liquid extraction with the aid of alkyl amine salts that are dissolved in an inert, organic solvent. The cadmium ions are removed from the acid, aqueous phase and are enriched in the organic phase. The cadmium-containing organic phase, subsequently, is re-extracted with an aqueous salt solution, with the cadmium ions migrating from the organic phase into the aqueous phase. The process is particularly suitable for extracting cadmium from concentrated, highly acid aqueous solutions.

Abstract: A method and apparatus for minimizing errors in digital processing of electrical signals whereby a digital input signal is divided into a digital useful signal having a lower resolution than the input signal and into a digital error signal having lower resolution than the input signal. A deviation of the useful signal is reproduced from the input signal and a check is performed to see whether the sum error of a plurality of successive useful signal values crosses a prescribed upper or lower threshold. When a threshold is crossed, an error value of the useful signal which comes closest to this threshold is identified and the useful signal and the error signal of this signal value are corrected such that the sum error no longer crosses the threshold.

Abstract: This invention relates to a process for the preparation of 2-(methylthiomethyl)-6-(trifluoromethyl) aniline, [MTA], from ortho-aminobenzotrifluoride, (OABT), employing a single solvent transformation via a sulfilimine intermediate. A sulfilimine hydrochloride salt is prepared by the oxidative addition of dimethyl sulfide of OABT in the presence of N-chlorosuccinimide. Neutralization of the sulfilimine hydrochloride salt with aqueous sodium hydroxide followed by phase separation results in an organic phase containing free sulfilimine and an aqueous phase generally containing succinimide and/or sodium succinimide. In a preferred embodiment the phase separation is performed in such a manner to leave a catalytic amount of succinimide in the organic phase. The free sulfilimine catalytically rearranges at moderate temperatures in the presence of this succinimide catalyst to form MTA. The aqueous phase separated after neutralization of the sulfilimine hydrochloride salt contains succinimide and/or sodium succinimide which may be converted by the action of chlorine to N-chlorosuccinimide which in turn may be recycled to the first step in the process.

Abstract: A hard foreign body in a stream of cut crop being moved by a conveyor in an agricultural machine to a crop comminuter of the machine is detected by first compressing the stream of cut crop transversely of its displacement direction between a pair of feed elements one of which is movable toward and away from the other and generating an actual-value output corresponding to the acceleration of the movable element toward and away from the other element. This output is compared with a set point corresponding to an acceleration level not normally exceeded by the element when the crop stream contains no hard foreign objects. An error signal is generated when the actual-value output exceeds the set point. When the error signal is issued advance of the conveyor is stopped and/or a warning is issued. The actual-value output is only generated when the acceleration of the movable feed element exceeds a predetermined limit. The actual-value output is a voltage and the set point is also a voltage.
