Patent EP-0402468-B1 (EP)

Abstract: This invention relates to a continuous perfusion apparatus of a liquid for use in cell culture, hydroponics, breeding, and the like. The perfusion apparatus comprises (1) a container which is horizontally partitioned by an inner lid and whose upper part is open, (2) a hollow cylinder (A) and a small pipe (B) which penetrate through the inner lid to effect communication of the spaces above and below the inner lid with each other and (3) a blast pipe (C) for feeding air into a space below the inner lid. One of the ends of the hollow cylinder (A) is positioned above (a) the inner lid while the other end near (b) the bottom wall of the container. One of the ends of the small pipe (B) is positioned above (c) the inner lid while the other end immediately below (e) the inner lid. Its central part extends downward and is bent by 180 DEG  near the bottom wall of the container, but its lowermost part (d) is on a level a little above the lowermost end (b) of the hollow cylinder. After a liquid is fed into the container, air is blown into the space below the inner lid so as to lower an artificial water surface inside this space. When the artificial water surface reaches the lowermost part (d) of the small pipe, the air filled in the space below the inner lid escapes to the upper part of the inner lid through the small pipe (B) and the artificial water surface rises. When this surface reaches one (e) of the ends of the small pipe, lowering of the artificial water surface again takes place. In this manner, the artificial water surface moves up and down repeatedly to cause perfusion of the liquid in the container.

Abstract: Dans un pupitre de commande analogique-numérique de signaux audio, les signaux des canaux analogiques sont totalisés, éventuellement en même temps qu'ils sont traités. Pour former le signal analogique d'émission, un autre signal de canal An formé par la somme des signaux des canaux numériques convertie en somme analogique est additionné à ladite somme des signaux des canaux analogiques. Un signal numérique Dn dérivé de la somme des signaux de canaux analogiques convertie en somme numérique est additionné à la somme des signaux des canaux numériques, ce qui permet d'obtenir un signal numérique d'émission à même teneur de modulation que le signal analogique d'émission.

Abstract: Le détecteur décrit, qui sert à détecter des raccords (5) dans une conduite de gaz de fonte, comprend par exemple une sonde (1) comportant une bobine émettrice centrale (2) et deux bobines réceptrices (3, 4) placées espacées chacune sur un des côtés de la bobine émettrice. Au niveau d'un raccord, l'espace libre (6) entre les sections de la conduite produit un couplage magnétique différentiel entre la conduite et les deux bobines réceptrices (3, 4). Après l'application d'une impulsion de courant d'excitation produit par une unité de commande sur la bobine émettrice, une comparaison par soustraction des tensions induites dans les bobines réceptrices et de la mesure d'une tension appréciable indique que la sonde (1) se trouve au niveau d'un raccord. Dans un second mode de réalisation, la sonde (101) est pourvue d'un tuyau d'amenée d'un composé d'étanchéité (115) et de buses (120) depuis lesquels le composé d'étanchéité peut être vaporisé dans le raccord lors de sa détection.

Abstract: Objects of thermoplastic polymer foam such as, e.g., sheeting of polyolefins such as polyethylene, are treated at elevated temperatures effective to rapidly purge the foam of a substantial portion of the residual blowing agent. Significant economies are achieved by reducing the amounts of residual blowing agents (such as flammable, toxic or environmentally hazardous gases) to levels presenting no fire hazard or other safety hazards in times substantially less than required in conventional aging under ambient conditions. The processes can be carried out in ovens or other heating zones which form continuations of the basic production line, with the extracted blowing agents recycled or disposed of by combustion.

Abstract: An optical scanning system for a compact disc having a sinusoidal data track radially meandering, at a selected frequency, about the axis of rotation of the disc includes a first laser beam for reading data from the data track. A +1 level laser beam and a -1 level laser beam respectively track the opposite edges of the data track and generate a tracking error signal. The +1 level laser beam and the -1 level laser beam are separated, with respect to the disc, by a distance equal to an odd integer multiple of one half the wavelength corresponding to the selected frequency. The +1 and -1 laser beams are not modulated by the sinusoidal data track and standard tracking circuitry can be used to track the data track.
