Abstract: An arrangement for introducing audio-frequency signals into a power supply line containing a compensating capacitor, through a junction converter having primary winding which is connected with an audio-frequency signal generator. The secondary winding of the junction converter is connected in series with the compensating capacitors which are not located in a parallel branch line to the secondary winding of the junction converter, and thus do not represent a load on the audio-frequency signal. The audio-frequency signal is coupled into the power supply line through the compensating capacitors which are connected in series with the secondary winding, whereby the coupling in is effected, on the one hand, through one and, on the other hand, through two parallel-connected compensating capacitors.

Abstract: A PLA is constructed to improve random testing. Section circuits are provided that permit disabling sections of the output lines that are called segments so that the circuit can be tested one segment at a time. Selection circuits are also provided for enabling the product term lines only one at a time. Thus, while random test signals are conventionally applied to the PLA input terminals for test, only a small portion of the PLA is enabled for the test. Control signals for the selection circuits are generated randomly so that the portion of the PLA that is tested is varied randomly. 
     The PLA comprises an AND array 12 and OR array 14 from which an output is obtained from buffer 16. The AND 12 is driven from a partitioning circuit 15 comprising a two-bit decoder for each input signals U o ...U 3 . The signals U 0 ...U a , are provided by segment select circuit 34 which decodes control test signals t" to provide from a random generator and is controlled by signal T. INputs for the AND array 12 are derived from a logic array 36 driven by signals t 2 ...t 5  provided from a random generator through a second partioning circuit 37 controlled by a second signal T.

Abstract: For a method for heat-treating textile material, and for a tenter for carrying out the method, it is proposed to control the textile web velocity as a function of the point on the treatment path at which the maximum deviation in the amount of energy spent per unit time occurs. To determine this point on the treatment path it is not necessary, therefore, to measure the momentary temperature of the textile material directly or the temperatures of the treatment medium flowing in and out. Instead, it suffices to determine the individual valve positions which indicate the amounts of energy supplied per unit time, and to infer therefrom the site of the treatment path where the drying process is completed and the fixing process sets in.

Abstract: This invention is directed to a method for preparing a concentrated stable water-in-oil emulsion containing at least 40 weight percent of a water-soluble polymer, which method comprises as steps of (1) forming a stable water-in-oil emulsion containing at least one water-soluble monomer in an aqueous phase which is dispersed in a continuous oil phase, said emulsion of monomer containing an emulsifying amount of a water-in-oil emulsifier; (2) subjecting said emulsion of monomer to conditions sufficient to polymerize the monomer thereby forming a stable water-in-oil preconcentrate emulsion of a water-soluble polymer; and (3) concentrating said preconcentrate emulsion by removing at least a portion of the water from the perconcentrate emulsion. The invention is characterized in that prior to or during step (3), an inverting surfactant is added in an amount sufficient to reduce the bulk viscosity of the preconcentrate emulsion, but less than that which destabilizes the preconcentrate emulsion or the concentrated emulsion. 
     The concentrated emulsions prepared by the process of this invention are superior to conventional emulsions in that they have increased polymer solids, reduced oil content, lower bulk viscosity and greater stability than are characteristic in the conventional emulsions containing about 30 weight percent of solids. 
     In addition to their utility as additives in drilling muds, fracturing fluids and fluid mobility control agents in enhanced oil recovery methods, the emulsions prepared by the process of the present invention are also useful as flocculating agents for sewages, industrial wastes, mining streams such as coal slurries and mining effluents, as thickeners for coating formulations and as additives for the manufacture of paper.

Abstract: The assembly consists of a power-assisting servomotor (1) and a cantilevered master cylinder (15). It is mounted on a fixed wall (50) of a vehicle by means of at least one component (30) which transmits a force in a more or less straight line, and connects the master cylinder (15) directly to the fixed wall (50). The method involves a step in which a fixing component (34) is previously attached firmly to the opposite surface of the wall (50). The assembly is then assembled and fixed in place by manipulating the head (32) of the component transmitting the force which component is advantageously placed in a bracing pipe (27) having the same axial extension as the servomotor casing and connected to the said casing. All the operations can thus be carried out on the same side of the fixed wall (50). <IMAGE>

Abstract: Porte logique à entrées multiples susceptible d'être testée à fond sans le problème dit de la "logique inaccessible" posé par les dispositifs logiques conventionnels VLSI (à intégration à très grande échelle) et nouvelle méthode d'essai dynamique pour accroître la production sans défaut et analyser de manière simplifiée les défauts de sous-ensembles. Dans un mode de réalisation illustré de la porte logique (20) selon l'invention, le dispositif comprend la réplique d'un groupe hiérarchisé de six portes (10) à entrées à deux états possibles pour former une porte à entrées à trois états possibles, et on trouve deux de ces portes à trois entrées avec leur structure de commande logique sur une seule puce à circuits intégrés VLSI. Chaque porte à entrées à deux états (12) est commandée par son propre réseau logique programmé, permettant ainsi la sélection de l'une des 256 fonctions booléennes possibles pour chacune des portes à entrées à trois états sur une puce. Une méthode d'essai dynamique très judicieuse tire parti de l'architecture hiérarchique de la porte logique selon l'invention pour fournir une évaluation de haut en bas de chaque porte à entrée à deux états jusqu'à ce que la structure de six portes soit testée de manière exhaustive. La méthode d'essai est mise en oeuvre en appliquant de manière séquentielle aux portes à entrées à deux états leurs seize fonctions booléennes respectives et en affichant une topographie vidéo des signaux de sortie des portes qui seront conformes à une configuration donnée lorsque le dispositif est exempt de défauts.
