Abstract: A bipolar clock-controlled bistable multivibrator circuit arrangement having a static memory cell formed of a D-master-slave flip-flop with a first inverted output signal fed back to a data input and with feedback loops, respectively, for intermediately storing output signals of the master and the slave. A dynamic memory cell is formed of the D-master-slave flip-flop with a second inverted output signal fed back to the data input. The second inverted output signal has gate propagation times performing intermediate memory functions in place of the feedback loops and includes a synchronizing device connected between the static and the dynamic memory cells. Means are provided for setting the circuit of the static memory cell in operation at relatively high clock frequencies. Thereby the useful frequency range of the multivibrator is at least doubled.

Abstract: On creuse dans le sol, à un certain intervalle l'un de l'autre, deux trous (9, 10) qui sont aussi larges que le futur mur de fondation en tranchée, qui vont jusqu'à la profondeur définitive de celui-ci et qui sont remplis pendant leur formation d'un liquide thixotrope, si bien que finalement l'intervalle séparant les trous est supprimé et lui aussi rempli du liquide thixotrope et que le segment tout entier est ensuite rempli de béton depuis le bas jusqu'en haut alors que le liquide thixotrope est refoulé. L'invention prévoit, lors de la fabrication du mur de fondation en tranchée dans un sous-sol rocheux, de creuser dans le sol entre les deux trous (9, 10) un trou de forage (16) doté sur sa longueur d'une charge explosive (17), à l'extrémité inférieure des deux trous étant produit pendant un bref laps de temps un effet de pression permettant de faire sortir temporairement le liquide thixotrope des trous et de le refouler vers le haut, ainsi que de tirer la première charge explosive (17) pendant le refoulement du liquide thixotrope. Le refoulement peut être effectué par une seconde charge explosive (18) placée au fond de chacun des deux trous, les secondes charges explosives (18) étant tirées peu avant la première charge explosive (17). Il serait également possible de provoquer une poussée d'air sous pression au fond des deux trous (9, 10) peu avant la mise à feu de la première charge explosive (17).

Abstract: Afin de détecter les fuites entre les conducteurs d'un câble multipolaire, une tension de test (+V) est appliquée par un premier organe de commutation (20) tour à tour aux conducteurs d'un câble dont l'autre extrémité est déconnectée. Un deuxième organe de commutation (5) sélectionne tour à tour les conducteurs restants et, après chaque nouvelle sélection par le deuxième organe de commutation (5), le conducteur sélectionné est connecté momentanément à une tension prédéterminée, par exemple un potentiel de masse ou de terre, à l'aide d'un troisième organe de commutation (18, 19). Cela permet au condensateur formé par les deux conducteurs de se charger rapidement de sorte que les organes de mesure de courant (1, 2, 4, 11) servant à détecter le courant de fuite ne donnent pas de lectures parasites provoquées par le courant de charge. De même, toutes les combinaisons de paires des conducteurs peuvent être contrôlées rapidement, ce qui permet de tester de manière efficace des câbles comportant un grand nombre de conducteurs.
