Title: Paper machine clothings constructed of interconnected bicomponent fibers
Inventor: EAGLES DANA BURTON
IPC: D02G3/44
Filed: 1997-09-12
Granted: 2005-11-15
Abstract: The present invention is directed towards paper machine clothings comprised of interconnected bicomponent fibers (1, 2). In one embodiment of the invention, the paper machine clothing is comprised entirel y of bicomponent fibers in both the machine and cross machine direction. Advantage is taken of the unique bicomponent fiber structure, whi ch permits selection of different materials for the sheath and core components. For instance, the sheath material may have a melting point lower than the melting point of the core material. Accordingly, a fused, bonded structure (5) of bicomponent fibers can be formed where the sheath component has a melting point lower than the core component. By heating a fabric constructed of bicomponent fibers to a temperature greater than the melting point of the sheath component and lower than the melting point of the core component, with subsequent cooling of the fabric to below melt temperature of the sheath component, a fused, bonded structure will result.

Title: Method of protecting metals against corrosion
Inventor: DRAPER RUSSELL JAMES
IPC: C09J7/29
Filed: 1998-06-29
Granted: 2007-10-02
Abstract: A metal surface is protected against corrosion, by adhesively bonding a flexible, vapor impermeable metal-plastic laminate to the metal surface, the laminate comprising a metal foil and a plastic film having one surface bonded to one surface of the metal foil. The metal foil is remote from the metal surface with the plastic film being disposed therebetween, and acts as a vapor barrier preventing corrosive vapor, water vapor or oxygen from reaching the metal surface. Such a laminate can also be used for preventing corrosion of metal reinforcing bars in reinforced concrete structures.

Title: Optical biopsy forceps and methods of diagnosing tissue
Inventor: NISHIOKA NORMAN S
IPC: A61B19/00
Filed: 1997-05-07
Granted: 2004-03-02
Abstract: An integrated optical biopsy forceps device (10) and a method for tissue identification by optical analysis and biopsy sampling at a site within the body. The device includes an elongated catheter body for introduction into the body and navigation to an area of interest. An optical fiber (50) extends through the device, from the proximal end, whe re it may be connected to electro-optical spectral analysis equipment, to a distal tip for illuminating and receiving light energy from tissue at the location of the tip. The distal end of the device has a pair of cutting jaws (80, 81) pivotally mounted at the distal end of the catheter body and controlled by control wires (40, 41) extending through the catheter body to a control handle at the proximal end, or by the optical fiber. The device may be spectroscopically guided to a site of interest within the body. The fiber tip (50) is positioned coaxially with the jaws at the zone of contact and cutting of the jaws, and is retracted as the jaws close, so that the biopsy sample is taken exactly a t the spot being viewed by the optical fiber.

Granted: 2001-02-20
Abstract: Système hydraulique d'entraînement (1) pour chevalet de pompage, qui permet d'actionner une tige de pompage (6) dans un puits de pétrole. Le système d'entraînement comprend au moins un cylindre hydraulique (2) de tête de puits, une pompe hydraulique bidirectionnelle (7) et un maître cylindre (8). Ce dernier comporte un piston principal libre (11) et au moins une cloison fixe. Il comporte également une chambre (16) de fluide de travail, hydrauliquement reliée au cylindre de tête de puits, et au moins deux chambres (17, 18) d'entraînement du piston principal, hydrauliquement reliées à la pompe hydraulique. Le cylindre de tête de puits et la chambre de fluide de travail sont remplis d'un fluide de travail et définissent un système de fluide de travail, tandis que les chambres d'entraînement du piston principal et la pompe hydraulique sont remplies d'un fluide hydraulique et définissent un système d'entraînement hydraulique. Quand on inverse le flux de la pompe hydraulique, les chambres d'entraînement du piston principal sont pressurisées et dépressurisées alternativement, ce qui imprime des mouvements de va-et-vient au piston principal à l'intérieur du maître cylindre. Les mouvements de va-et-vient dudit piston provoquent alternativement une pressurisation et une dépressurisation de la chambre de fluide de travail et du cylindre de tête de puits, ce qui provoque le déplacement de la tige de pompe à l'intérieur du puits de pétrole.

IPC: F21V9/40
Filed: 1997-06-11
Granted: 2006-01-31
Abstract: The present invention relates to a multi-colour gobo for the projection of a multi-colour pattern, and to a method of manufacturing the gobo. On the basis of a multi-colour pattern that is colour-separated into single-colour components, the single-colour components are disposed in parallel planes in the gobo and at least two of these planes are mutually separated by means of a transparent substrate. The gobo may include a plurality of mutually superimposed disc-shaped and transparent substrates (1, 2, 3, 4) and each of the substrates may include a dichroic surface coating so as to form a colour filter. Combinations of the colour filters are able to reproduce the colours of the multi-colour pattern and respective colour-emitting surface coatings present a pattern that coincides with the pattern of corresponding colour components in the multi-colour pattern.

Title: Apparatus and method in a communication network
Inventor: POON KAR-FAT
IPC: H04W36/30
Filed: 1997-12-16
Granted: 2005-12-06
Abstract: The present invention relates to a method and a mobile station for use in a communications network of GSM type, or a type derived from GSM. According to the invention the identification of an unidentified BCCH carrier is initiated in the mobile station when said BCCH carrier on the basis of measured signal strengths is foreseen soon to be one of the strongest BCCH carriers with regard to the signal strength average value over a measuring period. The delay from the point in time when the BCCH carriers becomes one of the strongest BCCH carriers, taking into account the signal strength average values over a measuring period, to the point when the BCCH carrier has been identified can in many cases be reduced or in some cases eliminated. Thus the mobile station can report measurement data for the BCCH carrier to the network at an earlier stage so that handover to the corresponding cell may be made faster.

Abstract: This invention concerns a sports bag as a golf bag (1) equipped with an organiser insert. In another aspect, the invention concerns an organiser insert for a sports bag such as a golf bag. The invention involves an apertured plate (4), with each aperture (13) being sized and shaped to comfortably receive, for example, a golf club handle (19). Side walls extend below the plate (4) to define a single compartment beneath each aperture (13). A spacer (6) is associated with the side walls to keep them in fixed relationship with each other as they extend downwards. A retainer (7) is associated with each compartment to grip a golf club handle and resist its removal from the bag. Golf club handles (19) may be dropped or pushed into the bag (1) through the apertures (13) in the plate (4). They are gripped by the retainers (7) and are kept relatively still inside their respective compartments. In this way the clubs will be retained in fixed relative locations within the bag (1), and will be unlikely to fall out of the bag (1) during normal handling. The clubs may be easily removed by gentle upwards pressure applied to the club heads.

Abstract: Fluorescent indicators including a binding protein moiety, a donor fluorescent protein moiety, and an acceptor fluorescent protein moiety are described. The binding protein moiety has an analyte-binding region which binds an analyte and causes the indicator to change conformation upon exposure to the analyte.  The donor moiety and the acceptor moiety change position relative to each other when the analyte binds to the analyte-binding region. The donor moiety and the acceptor moiety exhibit fluorescence resonance energy transfer when the donor moiety is excited and the distance between the donor moiety and the acceptor moiety is small. The indicators can be used to measure analyte concentrations is samples, such as calcium ion concentrations in cells.
