Title: Canister vacuum cleaner with stair hugging swivel wheel assembly
Inventor: CROUCH JAMES T
IPC: A47L9/00
Filed: 2004-06-30
Abstract: A canister vacuum cleaner has a canister assembly and a stair hugging swivel wheel assembly. The stair hugging swivel wheel assembly pivotally connects to the canister assembly and has both a pendulum and a wheel rotatably mounted to a housing thereof. During use, the pendulum projects from the housing under the influence of gravity to inhibit or otherwise prevent the stair hugging swivel wheel assembly from pivoting whenever the canister assembly becomes oriented in an inclined position, such as when placed on a stairway. Preferably, the pendulum mates with a recess in the canister assembly co-located with a circular track in which the stair hugging swivel wheel assembly pivots.

Title: Means and methods for breaking noncovalent binding interactions between molecules
Inventor: OVAA HUIB
IPC: C07K14/705
Filed: 2006-01-25
Abstract: The present invention concerns multimeric proteinaceous molecules comprising at least two members that bind each other via a region of noncovalent interaction, wherein a first of said members comprises a conditionally reactive group that, when activated, cleaves a covalent bond within said first member. Cleavage of the covalent bond results in a reduction in the binding strength with which the at least two members bind to each other via said region of noncovalent interaction.

Title: Method for spectroscopy of surface plasmons in surface plasmon resonance sensors and an element for the use thereof
Inventor: HOMOLA JIRI
IPC: G01N23/20008
Filed: 2006-01-12
Abstract: The method of spectroscopy of surface plasmons consisting in that electromagnetic wave is made incident on a diffraction grating on which surface plasmons excitation and dispersion of wavelength spectrum of the electromagnetic wave are simultaneously performed through diffraction. Changes in spatial distribution of intensity in the wavelength spectrum of the diffracted electromagnetic radiation due to the excitation of surface plasmons are measured. The spectroscopy of surface plasmons can be simultaneously performed in at least two diffraction gratings or different areas of a single grating using at least two electromagnetic waves or different parts of a single electromagnetic wave. The electromagnetic wave can be emitted from at least two monochromatic or a single polychromatic source of electromagnetic radiation. The characteristic of the wavelength-dispersed diffracted electromagnetic radiation is usually detected with at least two individual detectors, a linear array of detectors or two-dimensional array of detectors.  The sensor element (1) of a multichannel SPR sensor encompasses one or multiple diffraction gratings which are coated or partially coated with a metal layer (7) for excitation of surface plasmons (2). At least one sensing area (12) of the sensor element (1) is fully or partly coated with a layer containing selected molecules for study of molecules and their interaction or for detection of chemical or biological substances.

Abstract: A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system housed within or above a wound dressing member. The micropump system includes a miniature pump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed without the need for a cumbersome external vacuum source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used. The patient does not need to be constrained for any period of time while exudate is being removed from the wound.

Abstract: A method of removing iron oxide scale from processed sheet metal comprises the steps of: providing a surface conditioning apparatus (10); and conditioning a surface of the processed sheet metal (46) with the surface conditioning apparatus (10). In general, the iron oxide scale generally comprises three layers prior to surface conditioning: a wustite layer (88) a magnetite layer (90) and a hematite layer (92). The wustite layer is bonded to a base metal substrate of the processed sheet metal. The magnetite layer is bonded to the wustite layer, and the hematite layer is bonded to the magnetite layer. The surface conditioning apparatus (10) has at least one surface conditioning member (70). The step of conditioning the surface of the processed sheet metal includes bringing the at least one surface conditioning member into engagement with the surface of the sheet metal. The surface conditioning member is brought into engagement with the surface in a manner to remove substantially all of the hematite and magnetite layers from the surface, and in a manner to remove some but not all of the wustite layer from the surface, so that a portion of the wustite layer remains bonded to the base metal substrate of the processed sheet metal after surface conditioning.

Abstract: L'invention concerne un procédé, un système et un dispositif de stockage de programme destinés à prédire une propriété d'un fluide, par exemple la production d'un fluide à partir d'un réservoir souterrain contenant du pétrole lourd entraîné par du gaz. Le procédé implique notamment de développer une corrélation de ligne de base de la perméabilité aux gaz relative k rg par rapport à la saturation en gaz S g. Une corrélation dépendant du nombre capillaire est déterminée en capturant la relation entre au moins une valeur de saturation en gaz critique S gc et un nombre capillaire N ca, et la perméabilité relative aux gaz k rgro et le nombre capillaire N ca, en se basant sur une pluralité de vitesses d'épuisement. Les nombres capillaires N c sont calculés pour une pluralité de cellules dans un modèle de réservoir représentatif du réservoir souterrain. La corrélation de ligne de base est ensuite ajustée pour correspondre à l'un de S gc et k rgro choisis dans la corrélation dépendant du nombre capillaire au moins, afin de produire une pluralité de corrélations de ligne de base ajustées correspondantes. Les perméabilités relatives aux gazK rg pour la pluralité de cellules sont choisies à partir des corrélations de ligne de base ajustées correspondantes. Une simulation de réservoir est alors exécutée en utilisant les perméabilités relatives choisies k rg pour prédire une propriété d'au moins un fluide dans un réservoir souterrain contenant du pétrole lourd entraîné par du gaz.
