Title: Nested bellows expansion member for a submersible pump
Inventor: MERRILL DANIEL A
IPC: F04D13/08
Filed: 2005-05-24
Abstract: A multi-diameter bellows for use in a seal section of a submersible pump. The bellows is adapted to surround a shaft that communicates the motor with the pump. The bellows is made of a first collapsible section and a second collapsible section. The volume of the bellows is varied by moving a coupling member that attaches the first collapsible section to the second collapsible section. The coupling member has an outside portion for connecting to the second collapsible section and an inside portion for connecting to the first collapsible section. The coupling member additionally has a transitional section between the outside portion and the inside portion. The transitional portion of the coupling member allows the inside portion to be located within the second collapsible section, i.e., allows the collapsible sections to be "nested", which increases displaced volume for a given stroke length of the coupling member.

Title: Detecteur a bande etroite
Inventor: FOURET JOACHIM
IPC: H03H21/00
Filed: 2002-12-05
Abstract: L'invention concerne un détecteur de signal à bande étroite présentant un filtre adaptable ainsi qu'un dispositif de régulation conçu pour réguler la fréquence du centre et la largeur de bande dudit filtre, afin de poursuivre le signal à bande étroite. Une meilleure régulation dudit filtre peut être réalisée en fondant la régulation de filtre sur la comparaison de la sortie et de l'entrée dudit filtre, cette comparaison donnant une mesure plus directe de la manière dont est suivi le signal à bande étroite. Dans le cas d'un filtre coupe-bande, si il y a une poursuite faible, ledit dispositif de régulation peut être orienté rapidement vers une vitesse de poursuite améliorée. Autrement, pour une bonne poursuite, ladite régulation peut être orientée vers la précision de poursuite. Cela permet d'atteindre une vitesse et une précision des équipements de détection à faible charge computationnelle. Des applications comprennent des signalisations de télécommunications ou une détection de tonalité de données. De nombreux signaux à bande étroite peuvent être détectés par une cascade de filtres.

Title: Method and kit for primer based multiplex amplification of nucleic acids
Inventor: HAN JIAN
IPC: C12P19/34
Filed: 2004-10-13
Abstract: Disclosed is a novel method for diagnosis or differential diagnosis of disease agents and secondary disease agents. The method disclosed uses a novel amplification strategy termed TemPCR to allow sensitive and specific amplification of target sequences from any disease agents and/or secondary disease agent whose nucleic acid sequence is known. The TemPCR method utilizes at least one set of target enrichment primers specific for the disease agent or secondary disease agent to be detected (present at a low concentration) and at least one pair of shared target amplification primers (present at high concentrations). At least one pair of said target enrichment primers comprises a binding sequence for the target amplification primers. Therefore, the use of the TemPCR method allows multiplex amplification reactions to be carried out without the need for empirical optimization of the multiplex amplification parameters. Methods for nucleic acid isolation and the detection of the target sequences are also disclosed for use with the TemPCR method.
