Abstract: A fairing for a modular blade of a wind turbine generator, comprising including a joining zone disposed between two consecutive modules of the modular blade. The fairing is comprised of different components; the suction side fairing, the pressure side fairing and auxiliary components, such as tabs to facilitate the joining of the components. The leading edge fairing and the trailing edge fairing are constituted of an elastomeric material, preferably silicone, supported in a rigid glass fibre framework in order to absorb the warping experienced by the blade during the operation thereof. The attachment elements employed to join the fairings together and to the setbacks of the blade shell are rivets or similar. All the fairings incorporate the metal elements necessary to be equipotentially bonded, being linked to the lighting down-drop.

Abstract: A compensation element, in particular a filter system, that is configured for volume compensation for a freezing medium. The compensation element includes an elongated hollow body with a first end and a second end, at the first end a coupling area being situated which closes the hollow body, and the second end in particular being open, the compensation element having an elastically reversible design in order to return back to the initial state after a deformation from an initial state that has taken place due to ice formation by the medium, and the hollow body having a cross section with a circumferentially closed outer area, and including an inner structure that is situated at an inner circumference of the outer area.

Abstract: A computer-implemented method of generating a queryable database (109). The method receives a corpus of free text documents (120) containing confidential data, the free text documents being related to the same domain. A trained Natural Language Processing (NLP) system (104) assigns one or more abstract named entities to each free text document in the corpus. The abstract named entities of each free text document are stored in a queryable database configured to provide aggregated information regarding the named entities. The NLP system is configured such that the abstract named entities are recognised and disambiguated with a precision between 0.75 and less than 1 and a recall between 0.75 and less than 1, and such that the ratio of precision and recall is between 0.7 and 1.3; wherein the queryable database is free from the addition of artificial noise by an artificial noise generation algorithm.

Abstract: The process is described for the dry mixing of fibers of different types and sizes with materials formulated with cementants or agglutinant components, granular aggregates and able to include or otherwise other additional ingredients. The principal characteristics of the process are to ensure a correct incorporation of the fibers with the rest of the materials, increase the mechanical fastening of same with the rest of the components and facilitate the use of formulas with high fiber content (over-fibration).

Abstract: A two-stage linear actuator particularly applicable to aircraft control surfaces. The first stage comprises a rotary input shaft driven by an electric motor having a helical threaded zone in its external surface at its inner end and a plurality of first helical roller gears configured to engage with the rotary input shaft in its helical threaded zone for rotating together. The second stage comprises a plurality of second helical roller gears configured to engage with the first helical roller gears for rotating together and with an output shaft having a helical threaded zone in its external surface at its inner end for converting the rotation of the second helical roller gears in a linear movement of the output shaft.

Abstract: Transmission of data and audio messages between tanker and receiver aircrafts to facilitate air refueling operations using a boom device, wherein the method includes transmitting a data message from one aircraft to the other aircraft as an analog signal via the electro-magnetic connection which is also used for transmission of audio messages between the aircrafts which may be operating in a radio silence environment.

Abstract: A system for detecting the status of a tube for fuel transfer. It includes a nozzle for a telescoping tube employed in air to air refueling and transfer of fuel on a tanker aircraft with a system that detects the status of the connection of the nozzle with respect of a receptacle in a receiving aircraft, the system detecting the characteristics of the status of the connection of the nozzle in the receptacle by direct measurement of parameters in the nozzle itself of the tanker aircraft.

Abstract: The invention provides transmission methods of messages between a tanker aircraft and receiver aircraft that facilitate air refueling operations using a boom device in, particularly, radio silence environments. In the case of data messages, the method comprises steps for transmitting a message from the aircraft that emits the message to the target aircraft as an analog signal via the electro-magnetic connection which is used for contact detection and disconnection and audio communications between the tanker aircraft and the receiver aircraft in radio silence environments. In the case of audio and data messages it is transmitted a signal resulting from mixing analog signals corresponding to both messages in a way that allows their separation at the target aircraft.

Abstract: This invention relates to a cement or cementitious composition with synthetic or natural fibers and/or microfibers with caliber or gauge smaller than 0.0508 mm (2 mils), in a proportion from 0.2 to 1.5% of total weight of composition when dry. Aggregates and additives that achieve thixotropy, plasticity, which preserve its dimensional structure and integral mechanical bonds may also be included. These above ingredients are included to create a composition suitable for modeling (i.e., a petrified material, cement, mortar, or concrete with extraordinary and novel characteristics). This composition is also useful for constructing, machining, restoring or creating forms with or without structures. Furthermore, the composition solidifies without contractions, fissures or cracks.
