Abstract: Le dispositif décrit (15, 16), qui sert à aspirer une substance de remplissage fluide à travers une paroi d'un sac (10) dont les parois sont souples, comprend un premier élément (15) présentant un trou traversant et une surface de scellement annulaire (32) entourant le trou traversant, un second élément (7) présentant une surface de scellement annulaire (32), ainsi qu'un organe de séparation (25) s'étendant radialement vers l'intérieur de la surface de scellement et destiné à couper une paroi du sac. Les premier et second éléments comportent des organes de blocage agissant conjointement, qui s'engagent l'un dans l'autre de façon à se bloquer mutuellement, lorsque l'organe de séparation pratique une coupe à travers la paroi correspondante. Les surfaces de scellement annulaires sont amenées en contact étanche avec une paroi du sac, de sorte que les premier et second éléments entrent en contact étanche avec la face extérieure d'une paroi dudit sac, pendant que les surfaces de scellement annulaires se fixent à la paroi respective par une pression adhésive. L'organe de séparation est constitué par une partie en forme de poinçon du second élément, de sorte que les deux parois du sac soient perçées avant que l'organe de séparation pénètre dans le trou traversant du premier élément et libèrent un passage (43) pour la substance de remplissage. L'organe de séparation ou la partie en forme de poinçon, respectivement, et le trou traversant du premier élément étant engagés l'un dans l'autre de façon à se bloquer mutuellement, les premier et second éléments sont mobiles l'un par rapport à l'autre dans le sens de l'obturation de l'organe de séparation et dans le sens contraire à cette direction d'obturation.

Abstract: Un système convertisseur numérique-analogique comprend un système logique qui reçoit des signaux d'entrée et un signal d'incrément/de décrément, et produit un mot numérique composé des bits les plus significatifs et les moins significatifs. Le système comprend deux CNA présentant des débits et des capacités de données séparés afin de convertir respectivement les bits les plus significatifs et les moins significatifs, le débit du second CNA étant supérieur à celui du premier CNA. Un circuit de combinaison produit un signal analogique représentatif du mot numérique provenant de la première et de la seconde sorties analogiques. Le débit des sorties combinées peut être aussi rapide que celui du second CNA, et la capacité des sorties combinées peut être aussi grande que celle du premier CNA. Le système comprend aussi un circuit de suivi et de blocage qui maintient la valeur de la sortie du premier CNA jusqu'à ce que des erreurs de commutation soient éliminées.

Abstract: To determine water-soluble strong acids in air, the quantity of air to be analysed is passed over an absorption solution to absorb the acids and then separated again. According to the invention, the solution containing the acids and the carbon dioxide which interferes with the analysis is brought into contact with air freed from carbon dioxide in a second step, with the result that it is freed from CO2 without the dissolved acids being removed at the same time. The solution containing the dissolved acids is then fed to a measuring cell comprising a combination pH measuring cell having a meter connected to its output. In the cell, the acidity of the solution and, consequently, the concentration of strong acids are determined and indicated. An apparatus for carrying out the method according to the invention has also been developed. …<IMAGE>…

Abstract: Two electrical voltages (Ud, Uq) which are offset through 90 DEG with respect to one another are intended to be monitored for every possible combination such that the resultant voltage (UR) exceeds a maximum value (Umax) as little as possible. The monitoring space, which is circular in an ideal manner, is for this purpose replaced by a polygonal monitoring space, preferably an octagon.

Abstract: In order to facilitate laser inscription or laser decoration of transparent substrates using a neodym laser, the invention provides that an auxiliary layer containing two types of transition-metal ions which differ in valency or atomic number is applied to the substrate. The laser radiation is absorbed in the auxiliary layer and thus acts indirectly on the substrate. In this way, a uniform image can be produced even at relatively high inscription rates.

Abstract: The twin-dispensing cartridge for two-component pastes has two supply cylinders (2, 3), having different diameters and in each case an outlet opening (4, 5), and a transition piece (7) which is mounted upstream of the supply cylinders and has a joint outlet for the components for connection to a mixer pipe (20) and dispensing channels (8, 9) adjoining the outlet openings. In order to avoid proportionally too little paste flowing out of the cylinder with a smaller cross-section when the closure is removed and at the beginning of the dispensing operation, the ratio of the volumes of the dispensing channels (8, 9) is selected such that it corresponds to the ratio of the volumes of the assigned supply cylinders (2, 3). In a preferred exemplary embodiment, the adaptation of the volume to the outlet opening (6) of the supply cylinder with the smaller volume (3) is brought about by an insert (21) in the corresponding dispensing channel (9). Both openings can be closed by a common closure.
