Abstract: Une soupape régulatrice d'écoulement comprend un manchon alésé (68) qui s'étend depuis une première ouverture (A) et contient une tige (20) coaxiale et espacée par rapport au manchon alésé. Une bobine coulissante de compensation (30) montée entre le manchon alésé (68) et la tige (20) peut se déplacer de façon à fermer complètement une deuxième ouverture (B) ou à la laisser partiellement ouverte. Un ressort de commande (36) maintient la bobine (30) en position d'ouverture, mais la presssion d'un fluide s'écoulant depuis la première ouverture (A) dans un passage (34) qui traverse la paroi de la tige peut s'appliquer à la bobine (30) de façon à l'amener à la position fermée. Un élément de soupape (18) pourvu d'un orifice établit le débit nominal voulu, et la chute de pression à travers la bobine (30) la maintient dans une position telle que le débit voulu s'établit. Un ressort de commande (50) de l'élément de soupape peut être utilisé pour mainternir l'élément de soupape en position fermée jusqu'à ce que la pression s'élève jusqu'au seuil voulu.

Abstract: An apparatus is provided to sequentially form and transport sheet material assemblages (28) to a receiving location (22). The apparatus includes a collating conveyor assembly (26) which is operated to form the sheet material assemblages. A gripper conveyor assembly (32) sequentially grips sheet material assemblages formed by the collating conveyor assembly and transports them to a receiving location (22). A receiving conveyor (34) transports the sheet material assemblages from the receiving location. The gripper conveyor assembly (32) includes a plurality of grippers (98) which are sequentially moved beneath the collating conveyor assembly with the grippers fully open and facing upwardly. Sheet material assemblages (28) are sequentially dropped from the collating conveyor assembly (26) downwardly into the upwardly opening grippers (98). Each of the grippers in turn is closed to clampingly grip the sheet material assemblages (28). The grippers are then moved to the receiving location (22) and opened with the grippers facing downwardly to drop the sheet material assemblages onto the receiving conveyor (34).

Abstract: This circuit also generates the most optimum tracking of the slicing level (sp) in the case where there are many successive zero transitions of the teletext signal and largely prevents locking into one of two otherwise stable states. This is essentially achieved by the fact that the accumulator (a2) and the sign inverter (w1) are supplied with a zero signal via the two change-over switches (u1, u2) if many successive zero transitions are determined by means of the logic circuit (gc). <IMAGE>

Abstract: Aqueous fluids, such as chemical reaction solutions or effluents from chemical production plants or dye houses, containing organic compounds and salts of polyvalent inorganic acids, preferably sulfates, are adjusted to a pH value in the range below about 4, concentrated by a membrane treatment and separated into an aqueous retentate concentrated with respect to the organic compounds and an aqueous permeate substantially free of organic compounds. Under these strong acid conditions an effective concentration of the organic compounds without the disturbing increase of the osmotic pressure caused by the presence of said sa!ts can be reached. The concentrates can be easily disposed of and the permeats, for example effluents substantially free of any organic compounds can be discharged into a waste water plant for further treatments and purification.
