摘要： On décrit un procédé de détection et/ou de contrôle de la perte ou de la détérioration de la fonction rénale qui consiste à faire réagir un échantillon clinique prélevé sur un patient présentant une perte ou une détérioration présumées ou confirmées de la fonction rénale avec un composé capable d'interagir avec un composé à radical libre pour former un produit d'addition à radical stable, et à détecter la présence dudit produit d'addition par la spectroscopie à résonance paramagnétique électronique. A cet effet on prévoit l'utilisation d'un spectromètre à résonance paramagnétique électronique, qui est adapté au fonctionnement dans un champ magnétique restreint autour du champ central du signal en cours de détection.

摘要： Zonal magnification of a selected area of an image produced by Echo Planar Imaging is achieved by taking images of a defined area in the presence of a selective 180° R.F. control pulse so that subsequent processing produces a magnified image of the selected area with enhanced resolution.

摘要： A sequence of a pair of r.f. pulses (90 x ° and 90 y °) is applied to a solid being imaged with a time interval (τ) after each pulse. A static magnetic field is maintained and a magnetic gradient field is superimposed in the said time intervals, the time integrals of the gradient magnitudes of the gradient fields being equal. A free induction solid echo signal is detected at the end of the second time interval. The sequence is repeated for different values of the time integral are to obtain a set of signals and Fourier transformations with respect to the said time integral are then carried out on the set to obtain one-dimensional information. Two-dimensional information can be obtained from a plurality of sets of signals, each set being obtained in the presence of an additional orthogonal gradient field of differing value for each set.

摘要： Discriminating means (D S ,D R ) are coupled to receive signals from a protected transmission circuit (2). The discriminating means (D S , D R ), also receives from a directional detector (DD) signals indicating whether any fault which occurs is forward of, or reverse of, a predetermined point. The discriminating means is arranged to produce an output signal (T S ,T R ) to trip a circuit breaker (4) of the protected circuit (2) only if a fault occurs within the protected circuit (2). In this respect, the discriminating means (D S ,D R ) only outputs a trip signal if it receives within the same time period both a signal from the directional detector indicating that the fault is appropriately located, and high frequency signals from the protected circuit (2). Thus the invention utilises the high frequency noise invariably generated when faults arise in transmission systems.
The invention has the advantage that it provides good discrimination of faults without requiring communication links between discriminating means at each end of a protected circuit, as has previously been necessary.摘要翻译： 鉴别装置（DS，DR）被耦合以从受保护的传输电路（2）接收信号。 识别装置（DS，DR）还从方向检测器（DD）接收指示发生的任何故障是否在预定点的前面或后面的信号。 识别装置被布置成仅在受保护电路（2）内发生故障时才产生输出信号（TS，TR）以跳闸保护电路（2）的断路器（4）。 在这方面，鉴别装置（DS，DR）只在同一时间段内接收到来自定向检测器的指示故障适当定位的信号和来自保护电路（2）的高频信号 ）。 因此，本发明利用在传输系统中出现故障时总是产生的高频噪声。 本发明的优点在于，如先前所必需的，其提供了对故障的良好鉴别，而不需要在被保护电路的每一端的鉴别装置之间的通信链路。

摘要： A capacitor has a top plate 2 in the form of a photodiode assay and a bottom plate 2. An RF source 3 is connected between plates 1 and 2. Insulating or semiconducting material to be tested is inserted between the plates 1 and 2 to act as dielectric. Where a printed circuit board or other conductive electrical component is to be tested it forms bottom plate 2. A flying spot scanner 11 produces a modulated light beam 12 which scans the top surface of plate 1. The resulting modula-ted photocurrent envelope is detected and displayed in a display monitor 15 in synchronism with the scanning beam.

摘要： A switched coil arrangement is connected in a bridge configuration of four switches S 1 , S 2 , S 3 and S 4 which are each shunted by diodes D,, D 2 , D 3 and D 4 so that current can flow in either direction through a coil L depending on the setting of the switches. A capacitor C is connected across the bridge through a switch S 5 to receive the inductive energy stored in coil L on breaking the current flow path through the coil. The electrostatic energy stored in capacitor C can then be used to supply current through the coil in the reverse direction either immediately or after a time delay. Coil L may be a superconductive coil. Losses in the circuit can be made up by a trickle charge of capacitor C from a separate supply V 2 .
