摘要:
Provided are reactive compositions for making a polyurethane-based rain-erosion protective coating for rotor blades, the reactive composition comprising an isocyanate-reactive component and an isocyanate-functional component and wherein the isocyanate-reactive component comprises a first component i) being a short chain hydroxyl-functional compound having two terminal (α-ω) hydroxyl groups, a molecular weight of less than 250 g/mole and containing at least 2 carbon atoms and a second component ii) comprising a high molecular weight hydroxyl-functional compound having two terminal (α-ω) hydroxyl groups and a molecular weight of at least 250 g/mol and comprising one or more units selected from oxyalkylene units and polyoxyalkylene units and wherein the isocyanate-functional component is an isocyanate prepolymer of the general formula NCO—Z—NCO, wherein Z is a linking group comprising at least two urethane (—NH—CO—O—) units and additionally one or more units selected from alkylenes, oxyalkylenes, polyoxyalkylenes, alkylene esters, oxyalkylene esters, polyoxyalkylene esters and combinations thereof. Also provided are protective coatings obtained from the reactive compositions and methods of applying the coatings to articles.
摘要:
A method of forming unique, private, personal, virtual social networks on a social network system that includes a database storing data relating to corresponding user entities. The method includes: a first user entity sending an invitation to a second user entity, recording in the database the second user entity as a direct contact of the first user entity and determining that third user entities, directly connected to the second user entity, are indirect contacts. A unique, personal, social network formed from direct and indirect contacts is thereby created for each user entity. Each user entity is able to control privacy of its data with respect to other user entities depending on the connection factor to that other entity and/or that other entity's attributes.

摘要:
Approaches described in this disclosure are generally directed to methods and devices for delaying a write turn-on of a memory device. A write control signal from a memory controller to a preamplifier of a storage device is asserted. A warm-up interval of write drivers of the preamplifier is initiated, the warm-up interval having a duration of predetermined length. Data is transmitted to the write drivers during the warm-up interval.
摘要:
Methods of coating surfaces of a (e.g. drinking water) pipeline and pigments dispersions are described. The coating composition of the method and pigment dispersion comprise one or more alkyl phenyl ester compounds wherein the alkyl group comprises at least 8 carbon atoms.

A first instance of the application can be executed. While the first instance of the application is executing, at least one request to access the application (first access request) can be processed by directing the first access request to the first instance of the application. Further, a request to update the application can be received. Responsive to the request to update the application, at least one new application component corresponding to the update request can be installed. A second instance of the application can be executed. The second instance can include at least one new application component.
摘要:
A method and system of tracking devices uses imaging and optionally tags. Tracking is performed when the identification information associated with the devices are initially received and exposed towards a scanning bar in an enclosure. This scanning bar scans at one or more predetermined intervals the one or more devices in the enclosure of hardware. The system for tracking devices includes an enclosure capable of receiving one or more devices positioned to expose identification information related to each device and a scanning bar movably coupled to the enclosure that passes over each of the one or more devices and captures images of the identification information exposed by each of the one or more devices.

摘要:
A method and system for immediate failure checking for lost message processing comprises receiving a first message of a web-service transaction comprising first message sequence information at a computing device in a transaction environment of a target web service, storing a first record of the first message within the computing device, receiving a subsequent message comprising corresponding message sequence information at the computing device, storing a second record of the subsequent message within the computing device, comparing the first message sequence information with the subsequent message sequence information using the computing device, identifying a transaction error using the computing device, if the subsequent message is not an initial message in a sequence of messages based on the comparing, reporting the transaction error from the computing device, and aborting processing of the web-service transaction if the transaction error has occurred, using the computing device.
摘要:
A system for enabling communication between an underwater fluid extraction facility and a remote location comprises a fibre-optic cable connected between the facility to the remote location, signal transmission means at the remote location for transmitting signals to the fibre-optic cable, a distribution hub in the facility for receiving signals from the other end of the cable and at least one secondary hub located at the facility in communication with the distribution hub. Communication between the facility and the remote location is effected using a Local Area Network. Preferably Ethernet signalling is used throughout the network.
