Abstract: Un procédé pour la récupération, sous une forme utilisable par l'homme, des protéines contenues dans les eaux résiduaires de l'industrie laitière. Le procédé s'effectue dans une série d'appareils comportant successivement un bassin de pré-neutralisation biologique, dans lequel les eaux résiduaires alcalines sont soumises à des fermentations acides et sont dessablées, un réacteur de neutralisation, pour acidifier davantage ces eaux par dépôt d'une zooglée naturelle sur des matériaux divisés contenus dans le réacteur; un floculateur pour coaguler les protéines de ces eaux sous forme de flocs protéiniques sous des conditions de pH contrôle, et un flottateur dans lequel les protéines sont flottées par des microbulles et ramassées par râclage. Un nouvel adjuvant de floculo-flottation est décrit; il modifie le pH isoélectrique dans le sens d'une diminution de la consommation d'acide d'appoint et permet l'étalement de la zone de pH où il y a floculation. Cet adjuvant de floculo-flottation comporte un co-adjuvant organique et un co-adjuvant minéral injectes séparément dans le floculateur. Les protéine récupérées sont solubilisées par des oses. Le produit final du procédé, qui peut être une poudre, sert entre autre â l'alimentation animale, à l'industrie pharmaceutique et à l'industrie des cosmétiques.

Abstract: Disclosed is a novel polypeptide useful as a leader or trailer peptide moiety in recombinant DNA protein production techniques involving fused protein methodology.  The polypeptide comprises an amphiphilic helix designed at the DNA level to have hydrophilic charged amino acid residues on one side of the barrel of the helix and nonpolar amino acid residues on the other side of the barrel of the helix.  When DNA encoding the helix is attached to a gene encoding a protein of interest, high level expression is achieved and inclusion bodies are spontaneously formed.  The inclusion bodies may be collected and purified easily by altering the ionic strength and/or pH of media used to dissolve the inclusion bodies.  After purification, the fused protein is cleaved to separate the amphiphilic helix from the product.

Abstract: IMPROVED SOLID ELECTROLYTE FUEL CELL AND ASSEMBLY                 ABSTRACT An improved fuel cell assembly includes a plurality of series-connected fuel cells each including an electrically conductive separator, a compressed or sintered oxide powder cathode contacting the separator, a solid electrolyte contacting the cathode and a compressed or sintered powder anode contacting the electrolyte. Each of the separator, anode, electrolyte and cathode includes two internal holes each at least partially in registration with each other so that a fuel and an oxygen-containing gas may be admitted to separate tubes in the cell. Preferably, a gasket is disposed in the opening in the cathode receiving the fuel to shield the cathode from the fuel. A second gasket is disposed in the opening in the anode receiving the oxygen-containing gas to shield the anode from oxygen. Oxygen admitted to one of the tubes reaches the anode by first diffusing through the cathode and then being lonically conducted through the electrolyte to the anode. Oxygen at the anode reacts with the fuel, releasing heat. A peripheral barrier may partially protect the anode from oxygen. In an alternative embodiment, each of the elements of the cell includes only one hole, all of which may be aligned to form a single tube for admitting fuel. In that embodiment, oxygen diffuses from outside the cell, through pores in the cathode. In other embodiments, a single central fuel tube may have a plurality of oxygen supply tubes.

Abstract: In some digital communications systems, such as the Integrated Services Digital Network (ISDN), problems may occur in recovering timing from signals generated by several terminals located varying distances from a common transmitter.  Timing recovery is facilitated by detecting a marker of a frame transmitted to the several terminal equipments, detecting a corresponding marker received shortly afterwards from one of the terminal equipments;  and sampling the received digital signal at a sampling instant delayed relative to a specific feature of the received marker, for example, a zero crossing immediately following a frame bit.  Preferably, the delay between the sampling instant and the occurrence of the specific feature used as a reference point is proportional to the time elapsed between detection of the outgoing or transmitted marker and detection of the incoming or received marker and hence proportional to the round trip propagation time.
