Title: Conotoxin peptide pviia
Inventor: TERLAU HEINRICH
IPC: C07K14/435
Filed: 1997-03-14
Abstract: A new peptide, k-conotoxin PVIIA, is disclosed. This peptide is found naturally in the cone snail Conus purpurascens and has the amino acid sequence Cys-Arg-Ile-Xaa-Asn-Gln-Lys-Cys-Phe-Gln-His-Leu-Asp-Asp-Cys-Cys-Ser-Arg-Lys-Cys-Asn-Arg-Phe-Asn-Lys-Cys-Val (SEQ ID NO: 1) where Xaa represents 4-trans-hydroxyproline, hydroxyproline or proline. This peptide together with a previously disclosed peptide, 6-conotoxin PVIA, act synergistically to rapidly immobilize fish which are injected with the two peptides. Injection of r.-conotoxin PVIIA alone results in different symptoms with an injected fish becoming hyperactive and then contracting and suddenly extending all major fins. This "fin-popping" occurs repeatedly resulting in a series of jerky movements, but injection of only k-conotoxin PVIIA does not immobilize or kill the fish.

IPC: B65G23/44
Filed: 1998-11-25
Abstract: A conveyor construction includes a frame, a drive section stationarily mounted to the frame, and a tensioning section mounted for longitudinal movement relative to the frame. The drive and tensioning sections each include a spindle, and a belt is engaged with the spindles. The frame defines an upper support surface disposed below the upper run of the belt, and mating engagement structure is provided on the belt and the upper support surface for preventing lateral movement of the belt relative to the upper support surface. The drive and tensioning sections include spaced side members, each of which defines an inwardly opening cavity for receiving a bearing assembly for rotatably supporting the spindle. The bearing-receiving cavity faces the spindle, and each side member defines outer wall structure which engages and supports the belt outwardly of the spindle.  The belt overlies the outer wall structure of each side member and the adjacent belt-engaging portion of the spindle, so as to seal the inwardly facing opening and prevent ingress of moisture or other contaminants into the bearing-receiving cavity. A drive and locking arrangement for imparting movement to the tensioning section and for selectively locking the tensioning section in position includes a pair of pinion carriers or retainer blocks mounted one to each side of the frame, with a drive pinion being rotatably supported by the retainer blocks. Each side member includes integrally formed gear teeth engageable with opposite ends of the drive pinion, and a drive pinion actuator is engaged with one side of the frame for imparting rotation to the drive pinion to extend and retract the tensioning section. A  locking arrangement is interconnected with the opposite end of the drive pinion, and functions to selectively frictionally engage the drive pinion with one of the retainer blocks to prevent rotation of the drive pinion and to thereby maintain the tensioning section in a desired position relative to the frame.

Abstract: Un dispositif de filtration (10) de l'eau par écoulement, alimenté par différence de niveau, comprend une chambre (11) abritant un filtre (30, 80) en spirale qui contient un matériau biocide, et une chambre de fixation annulaire. Plusieurs disques séparateurs poreux, un volume de milieu filtrant (64) et une membrane (70) à kystes sont positionnés sous le filtre en spirale et la chambre de fixation. Le dispositif (10) est efficace pour réduire de manière significative le nombre de bactéries, de virus et de kystes présents dans l'eau filtrée. Sa conception, à échelle variable, permet de l'utiliser dans les systèmes municipaux de traitement des eaux et dans d'autres systèmes. La configuration du trajet d'écoulement peut être un canal étroit d'une largeur minimale, doublé d'un matériau granulaire actif, qui améliore le rendement de la filtration et du processus de traitement, tout en maintenant à son minimum la résistance à l'écoulement. La géométrie en spirale ou hélicoïdale se prête à une disposition compacte quand la place est limitée. Le canal fluidique doublé de matériau granulaire brise le flux laminaire et crée un environnement inhospitalier pour la croissance des contaminants bactériens, comparable au biofilm que l'on trouve et décrit typiquement dans les systèmes de traitement de l'eau en dentisterie.

IPC: H04N7/24
Filed: 1998-02-16
Abstract: In an MPEG-2 transmission system, a plurality of programs each consisting of a plurality of elementary streams are multiplexed on a transport stream by a multiplexer (8). The transport stream is transmitted by the transmitting means (10) via a transmission medium (16) to a receiver (18). In the receiver (18) the signal is demodulated by the receiving means ( 12) and demultiplexed by the demultiplexer (14). In order to be able to find the different elementary streams which form a program, several tables are used. Said tables which can change over time are updated by information present in the transport stream. The tables are identified by a version number in order to be able to distinguish different versions of them. The version numbers are not necessarily subsequent numbers. In a prior art, transmission system filtering has to be performed on all possible version numbers to find updates of a table. In the transmission system according to the present invention, filtering is performed by only selecting sections having a version number which is different from the previous version numbers.
