Abstract: 1. Circuit associating an insulated gate field-effect transistor (30) with a bipolar transistor (31), the drain being connected to the collector and the source to the emitter, a control terminal (G) being connected to the gate, characterized in that the base (B) of the bipolar transistor is connected on the one hand to the gate (G) of the field-effect transistor via a threshold device (32) and on the other hand to the connection between emitter and source (S) via a resistor (33) of high value, as a result of which the circuit functions like a field-effect transistor for low control voltages and like a bipolar transistor for control voltages higher than the threshold value of the threshold device.
Patent EP-0041934-A1 (EP)
Inventor: LASZLO TOMAS PABLO NICOLAS
IPC: C08J9/42
Filed: 1981-06-09
Abstract: A foamed plastic and a method for its production are described. The foamed plastic has cavities which consist of open cells or pores. In at least a portion of the cavities, particles of water-insoluble hydrophilic polymer are homogeneously distributed, the particles being swellable to a gel in water. Examples of such polymer particles are granules of cross-linked dextran. The polymer particles are incorporated in the foamed plastic by being suspended in a liquid impregnating agent, such as ethanol-chloroform which is of substantially the same density as the polymer particles. A water-soluble binder, such as polyvinyl pyrrolidone, is also dissolved in the impregnating agent, and suitably also a plasticizing and surface active agent, such as a poloxamer. The foamed plastic is impregnated with the liquid suspension, whereafter the impregnating liquid is removed by drying. The polymer particles are anchored to the dried foamed plastic by means of the binder, whereas the polymer particles, on use of the foamed plastic product for, for example, treating a running sore, swell to form a gel such that they fill out the cavities of the foamed plastic and are retained because of steric hindrance. The foamed plastic product is int.al. usable as a bandage and/or for plugging to drain exudate from injured skin surfaces, such as running sores, and in the treatment of incontinence. Also non-clinical fields of use, such as the use of gel iodophore-provided foamed plastic for water purification, are included in the invention.

Abstract: Un circuit détecteur (214) pour détecter les états "raccroché" et "décroché" d'une ligne de communication comprend des détecteurs de courant et de tension (410 et 415, 416) pour générer deux signaux de référence. Un signal représente le courant s'écoulant dans la ligne, l'autre représente la tension de la ligne. Un circuit comparateur (412-414, 420, 421) compare ces deux références pour générer un signal de sortie représentant l'état raccroché lorsque l'intensité de l'un des signaux de référence est supérieur à l'autre. Lorsque l'intensité d'un signal de référence est inférieure à l'autre, le circuit comparateur génère un autre signal de sortie représentant l'état décroché de la ligne. De plus, lorsque la ligne est électriquement isolée de la terre, les deux signaux de sortie du circuit comparateur peuvent entraîner un opto-isolateur (431) pour générer deux signaux de sortie correspondants (en 419) électriquement isolés des signaux de sortie du circuit comparateur.
