Abstract: A crane apparatus and method are described for lifting a heavy load such as a wind-turbine generator unit 46 on to a wind-turbine tower 1. The crane is designed to climb up cables 3 attached to the top of the tower, carrying with it the cables 45 and lifting gear 31 which will be required for the main lifting operation. The crane comprises a pair of jib-frames 20 with boom arms 26, 27 which can be retracted during lifting and then deployed to a pivotable, loadbearing position once the crane is mounted at the top of the tower 1. Hydraulic strand jacks 31 and heavy-duty strands 45 are preferably used for the heavy lifting. In a preparation step, a load-bearing bracket assembly 13, 14, to which the jib-frames 20 will be secured, is hoisted up and fitted to the top of the tower 1. Once the lifting operations are complete, the crane assembly and the bracket assembly 13, 14 are lowered from the tower 1 and removed from site.

Abstract: An enhanced thermal interface material (TIM) gap filler for filling a gap between two substrates (e.g., between a coldplate and an electronics module) includes microcapsules adapted to rupture in a magnetic field. The microcapsules, which are distributed in a TIM gap filler, each have a shell that encapsulates a solvent. One or more organosilane-coated magnetic nanoparticles is/are covalently bound into the shell of each microcapsule. In one embodiment, (3-aminopropyl) trimethylsilane-coated magnetite nanoparticles are incorporated into the shell of a urea-formaldehyde (UF) microcapsule during in situ polymerization. To enable easy removal of one substrate affixed to another substrate by the enhanced TIM gap filler, the substrates are positioned within a magnetic field sufficient to rupture the microcapsule shells through magnetic stimulation of the organosilane-coated magnetic nanoparticles.

Abstract: An apparatus and method are proposed for incremental casting of concrete cantilever bridge sections. The main trusses which form the load-bearing frames of the apparatus are angularly splayed so that they are positioned outwards of the main load bearing webs of the to-be-constructed section of the bridge, while still being supported on the webs of the already-constructed section of the bridge. In this way, the region above and below the construction space is kept free for improved access.

Abstract: An apparatus includes an electronic component mounted on a substrate and metal conductors electrically connecting the electronic component. A conformal coating overlies the metal conductors and comprises a polymer into which a phosphine compound is impregnated and/or covalently bonded. Accordingly, the conformal coating is able to protect the metal conductors from corrosion caused by sulfur components (e.g., elemental sulfur, hydrogen sulfide, and/or sulfur oxides) in the air. That is, the phosphine compound in the polymer reacts with any corrosion inducing sulfur component in the air and prevents the sulfur component from reacting with the underlying metal conductors. Preferably, the phosphine compound in the polymer does not react with other components in the air (e.g., carbon dioxide) which would otherwise deplete its availability for the target reaction. The phosphine compound may be rendered completely non-volatile by covalently bonding it directly into the polymer backbone.

Abstract: A method, system and computer program product are provided for implementing dynamic noise elimination. A system frame includes a plurality of acoustical sensory devices monitoring the system for problem frequencies. The system frame includes a plurality of tubes. When the tube is open, airflow is allowed. When identified tubes are closed, quarter-wavelength attenuation is provided for a frequency in a range of frequencies, based upon a length of the tube when closed. Each of the plurality of tubes is selectively controlled to be operable open or closed at a particular length, responsive to identified problem frequencies.

Abstract: An early warning sulfur detection system for detecting the presence of corrosive gases, especially elemental sulfur (S8), in air employs a substrate that includes a polymer-bound phosphine compound having sulfur-getting functionality. The phosphine compound in the polymer reacts with any airborne elemental sulfur. This reaction is accompanied by a decrease in the fluorescence intensity (If) of the substrate. The If of the substrate is monitored in real time by a spectrofluorometer to detect a change in fluorescence intensity (?If). In an embodiment sited in a data center, an alarm is triggered if the ?If is above a predetermined threshold, thereby providing a real-time, early warning to IT professionals that corrective action is required to protect metal conductors from corrosion. Preferably, the phosphine compound in the polymer does not react with other components in the air (e.g., carbon dioxide).

Abstract: A heat exchanger for use, e.g., in a rear door of a server rack in a computer room, made up of pipes clad with a layer of a phase change material, such as a paraffin, so that latent heat is absorbed in the conversion from the solid to the liquid state. Preferably, each pipe in turn is opened by a control valve and chilled coolant flows through the pipe until the phase change material reverts back to the solid state. Then, the control valve is again closed, and the phase change material is further heated by waste heat so that it is melted once more. Preferably, the control valve for only one pipe at a time is opened, so that latent heat is being absorbed by the phase change material around all pipes but one.

Abstract: A method and an apparatus are for applying a rotationally driven pressure roller (4) onto a rotationally driven goods guiding roller (3) in stretching equipment for thermoplastic films. The pressure roller (4) is advanced in the direction of the goods guiding roller (3) by at least one first pressurizable piston-cylinder unit (7) in such a manner so that after the advancement an axis-parallel remaining stroke exists between the pressure roller (4) and the goods guiding roller (3). Then at least one second pressurizable piston-cylinder unit (8) operatively connected with the first piston-cylinder unit (7) carries out the remaining stroke, while maintaining the axis-parallelism, until a touching contact exists between the pressure roller (4) and the goods guiding roller (3). Then the pressure roller (4) becomes effective with a nominal pressing force onto the goods guiding roller (3).

Abstract: A method detects the beginning of combustion in an internal combustion engine (1) having several cylinders (2, 3, 4, 5), form a rotation speed signal determined for a shaft (6) of the engine (1). A segment signal (SS), whose signal length corresponds to an integral multiple of one or more full rotation of the shaft (6), is extracted from the rotation speed signal. A cylinder signal (ZS1, ZS2, ZS3, ZS4), which reproduces the operational state in a cylinder (2, 3, 4, 5), is generated from the segment signal (SS). The cylinder signal is transformed into a cylinder frequency signal (FS1, FS2, FS3, FS4) in an angular frequency range. Signal information indicating the beginning of combustion in the associated cylinder is extracted from the cylinder frequency signal at least one predefined angular frequency.

Abstract: The invention is essentially characterized in that in a first step a substrate is provided, which is coated with defined pattern of protrusions of a coating layer of a different material, so that an interface is defined between the substrate and the coating layer. As an example, the patterned coating layer can be applied by first forming an essentially homogeneous coating layer, which is then partially removed by means of photolithographic and etching techniques, leaving nanometer sized protrusions in that layer. As a next step, the surface provided with these structures is modified by selectively removing protrusions by means of a micro-device. Such a micro-device can be formed in a similar way to a scanning probe microscope (SPM) tip. The presence or absence of a protrusion represents a readable data bit information.
