Abstract: A downhole well system can use a fiber optic cable that can be positioned downhole along a length of a wellbore. The well system may include a top plug, a bottom plug, or both that are used to contain a cement slurry during a cementing operation. The movement of the top plug and bottom plug may cause acoustic noise along the downhole portion of the casing. A reflectometer may detect the acoustic noise from strain in the fiber optic cable and determine a location of the top plug or bottom plug downhole.

Abstract: A device, a system and a method for dispensing adhesive elements are provided. The device comprising a first holder, a second holder, and an alignment element. The first holder is configured to rotatably hold a film having adhesive elements and a protective layer attached on adhesive areas of the adhesive elements. The second holder is configured to receive the protective layer as the protective layer is peeled off the adhesive areas of the adhesive elements while the adhesive elements are moved towards an alignment element. The alignment element is arranged in a direction of movement of the adhesive elements and configured to receive and align the adhesive elements at a predetermined position on the alignment element.

Abstract: Wireless energy transfer system. Antennas are maintained at resonance with High Q. Techniques of maintaining the high-Q resonance matching are disclosed.

Abstract: A power transmission system produces a magnetic field at a source that is wirelessly coupled to a receiver. Both the source and receiver are capacitively coupled LC circuits, driven at or near resonance.

Abstract: The distribution of content items, such as news items, in a news publishing platform is governed by a plurality of interrelated factors. These factors include publisher bias, trust bias, and user-specific bias, which reflect the user's reading history, the social clusters to which the user belongs, the user's location etc. To model the relevance of each content item to a given user, a metric of the overall story strength is calculated in accordance with one or more of these biases. The content item is delivered to the target in accordance with the story strength metric.

Abstract: The distribution of content items, such as news items, is dependent in part upon the geographic relevance of the content item and the geographic community to which the target reader belongs. The geographic relevance of content items is determined and compared to a geographic profile for the reader at the distribution target. Where the function of geographic relevance exceeds a predetermined threshold, the content item is delivered to the target. As a result the reader is presented with content items that are more closely relevant to his geographic profile and desired interest threshold.

Abstract: A wireless powering and charging system is described. Such a system comprises a radio frequency transmitter (typically a home-appliance sized unit on a desk or a shelf) and a receiver (typically a small mobile unit carried by the user). When the user is in range of the transmitter, charging or powering can take place in the mobile unit.

Abstract: A method and apparatus for removing sulfur from a hydrocarbon-containing fluid stream wherein desulfurization is enhanced by improving the contacting of the hydrocarbon-containing fluid stream and sulfur-sorbing solid particulates in a fluidized bed reactor.

Abstract: In an advantageous process for producing powdered aluminium alloys which have a catalytic action or are capable of acting as precursors of catalysts, good results are obtained if the alloy is atomized with water and/or a gas at a temperature of 50.degree. to 500.degree. C. above its melting point and then cooled and dried.

Abstract: A frame-like roller carrier (40) which defines a sizing plane (C) normal to the longitudinal axis (A) of the can bodies is arranged in relation to awelding device (24) in such a manner that the sizing plane (C) coincides at least approximately with a welding plane (B) defined by the welding device. A plurality of sizing rollers (41) are mounted on the roller carrier (40), each for rotation about a roller axis (E) lying in the sizing plane (C). The sizing rollers (41) form a rigid ring of rollers through which the can bodies (1) can be moved. The roller carrier is divided into two half-frames (40), each of which carries a plurality of sizing rollers (41). The two half-frames (40) are adjustably supported on a common bridge (31). At least one of the half-frames (40) is connected to the bridge (31) by an adjusting drive (37) for the adjustment of the sizing rollers (41) carried by it.

Abstract: In an apparatus and a method of at least partially suppressing oxidation of can components or the like during resistance roller welding with the aid of an inert gas, the steps include welding the can components to one another, so as to obtain a hot welding seam, supplying the inert gas to the hot welding seam so as to envelop it at least partially, and to create a region of the inert gas in contact with the surrounding atmosphere, so that oxidation of the hot welding seam is at least partially suppressed.

Abstract: In a process for the moistening, impregnating and refining of a web of paper, carton, foil and the like, the web is treated in steam by the condensation effect of liquid supplied through nozzle bodies, and a precipitate is produced. An apparatus for carrying out the process has nozzle bodies arranged in a casing and connected to a steam supply, the nozzle bodies each containing a heater for heating the liquid and gas in a substantially pressureless condition in front of the nozzle outlets. Cooling elements are provided for the cooling of the web fed past the nozzle bodies, the whole being arranged such that, through the liquid being supplied, a condensation and thus a precipitation onto the surface of the web are produced.
