Title: A transmission method
Inventor: ASH JOHN DAVID
IPC: H04J3/00
Filed: 2002-04-29
Abstract: A transmission method in which a first signal frame, carrying a payload in a first part of the signal frame and second information in a second part of the signal frame, is transmitted intact between a signal source and a signal destination by copying the second information into the first part of at least one additional signal frame, transmitting both frames between the signal source and the signal destination and, at the destination, reconstructing the first signal frame by retrieving its original second information from the first part or parts of the additional signal frame or frames and placing the retrieved second information in the second part of the first signal frame. A  typical application of the transmission method lies in its use in an SDH  transmission system.

Abstract: L'invention concerne un dispositif de remplissage et d'alimentation de moules (400) ainsi qu'un procédé consistant à utiliser un tissu filtrant réfractaire (202) pour fermer une ligne de moules (100) acheminés en continu vers un dispositif multiétagé d'alimentation et de remplissage sous pression. La ligne de moules (100) est formée par des moules à sable vert à séparation verticale (101). Ces moules peuvent être remplis avec un métal fondu se solidifiant progressivement sous pression. L'alimentation sous pression résout les problèmes de rétrécissement au cours de l'opération de coulée. Le procédé comprend des modes de traitement de fonte ductile avec du magnésium en vue d'obtenir un graphite compacté. Un point de liage (242) du tissu filtrant (202) retient un alliage modificateur (630) sur les moules (101) se déplaçant à une vitesse élevée. Une colonne à commande par aspiration et pression (550) assure un écoulement constant vers les pièces coulées à parois minces, et une alimentation sous pression pour les pièces coulées lourdes. Les pertes d'énergie rayonnante sont contenues dans le système automatique. Le procédé et plusieurs composants de machine à usage déterminé constituent un système unifié pour le durcissement d'un liquide (600) tel qu'un polymère plastique, de pneus en caoutchouc ou d'un produit alimentaire, notamment dans la fabrication d'un bonbon au chocolat moulé.

Abstract: Novel enzyme variants including protease variants derived from the DNA  sequences of naturally-occurring or recombinant non-human proteases are disclosed. The variant proteases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease. Such variant proteases have properties which are different from those of the precursor protease, such as altered wash performance. The substituted amino acid residue correspond to positions 27, 45, 170, 181, 251 and 271 of Bacillus amyloliquefaciens subtilisin. Additional variants comprising at least one additional substitution at a positionselected from 1, 14, 49, 61, 87, 100, 102, 118, 128, 204 and 258 of Bacillus amyloliquefaciens subtilisin are also described.

Title: Metal implant with biocidal metal ions absorbed in the surface
Inventor: TURNER ANDREW DEREK
IPC: A61L27/00
Filed: 2003-03-25
Abstract: A metal implant for use in a surgical procedure is provided with a surface layer that is integral with the metal substrate, and which incorporates a biocidal material. The surface layer may be grown from the metal substrate, by anodising, and the biocidal material incorporated in it by ion exchange.  Alternatively the layer may be deposited by electroplating, followed by diffusion bonding so as to become integral with the metal substrate. In either case, silver is a suitable biocidal material; and both the release rate and the quantity of biocidal material should be low to avoid toxic effects on body cells. Electropolishing the surface before formation of the surface layer is also beneficial, and this may be achieved by electropolishing.
