A wind turbine rotor blade extension portion having a plurality of segments, located adjacent one another in a span-wise sense. An interface between adjacent segments is configured to minimise disruption to fluid passing thereover and to inhibit transmission of longitudinal loads between segments. Each segment has a first surface and a second surface. The first surface is spaced from the second surface at a proximal region of the extension portion and the first surface is connected to the second surface at a distal region of the extension portion to thereby generate a fair surface for a rotor blade to which the extension portion is connected, in use.

An antenna system with at least one tunable dipole element with a length adjustable conductive member disposed therein that enables the antenna to be used over a wide range of frequencies. The element is made of two longitudinally aligned, hollow support arms made of non-conductive material. Disposed longitudinally inside each element is a length adjustable conductive member electrically connected at one end. In the preferred embodiment, each conductive member is stored on a spool that is selectively rotated to precisely extend the conductive member into the support arm. The support arms, which may be fixed or adjustable in length, are affixed at one end to a rigid housing. During use, the conductive members are adjusted in length to tune the element to a desired frequency. The antenna is especially advantageous when configured as a Yagi-style antenna that can be optimally tuned at a specific frequency for maximum gain, maximum front-to-back ratio, and to provide a desired feed point impedance at the driven element. The antenna can also function as a bi-directional antenna by adjusting the reflector element to function as a director. An electronic control system allows the length of the conductive members to be manually or automatically adjusted to a desired frequency.

A fixing system for fixing a first component to a second component, wherein the first component is formed with at least one tab which can engages with at least one tongue formed on the second component, wherein the minimum of one tab is formed with at least one conical hole with which a projection, particularly a conical projection, provided on the tongue can be brought into engagement by latching therein.

A structure for an adjustable support of monitor including a main body connected to a monitor at a front and a positioning apparatus on an inside for controlling up and down movements of the monitor; and a connecting device pivotally connected with the main body on a front and coupled at a rear to a fastening device connected to a car. The positioning device includes a positioning member for positioning the monitor; and a stop member for releasing the positioning member to make the positioning member to move.

A conveyor belt for conveying plate elements in a machine for converting the elements that includes a belt body with longitudinal edges, joining edges, and a support surface for supporting the elements, and at least one assembly member arranged to join the joining edges, and extending in a direction of assembly which is oblique to the longitudinal direction, the belt body having a plurality of perforations for obtaining a vacuum on the support surface to immobilize the elements.

A bearing unit is provided in an inner peripheral portion of a sensor housing in which a sensor portion is installed. The sensor portion includes a sensor mounting substrate and a sensor fixed to this sensor mounting substrate. The sensor housing is provided with an axially extending substrate mounting groove formed in a direction of a chord which will define the circular section of the outer peripheral surface of the sensor housing. The sensor mounting substrate is mounted on this substrate mounting groove to install the sensor portion within the sensor housing.

An assembly includes a flexurally deformed panel, which is connected to a membrane tie by a linear connector and is tied by the membrane tie to form a geometrically stable pre-stressed structure. More than one panel may be flexurally deformed and tied together in an assembly and more than one membrane tie may be present within an assembly. Panels are typically semi-rigid sheet materials, for example metal sheets, plastic sheets, or sheets of composite materials, such as glass or carbon fibre reinforced plastics or resins. Membrane tie members are typically flexible, for example plastic films, fabrics or nets or arrays of rods or cables. The assemblies have many different geometric forms and many different practical applications. Assemblies may be relatively large, for example demountable and reusable shelters or flat-pack point-of-purchase display assemblies, or may be relatively small, for example a photograph or postcard display system.

An adjustable and portable soccer goal formed from tubular members in a horizontal, vertical and rearward slanting configuration. Segments of the members are used to form the members in varying sizes by adding or taking away segments vertically, horizontally and inclining to achieve desired lengths. The segments are joined together by molded joint connectors extending in most cases to the ends of two segments being joined together and as a cap or insert in other situations when more than two segments are joined at the same location. The soccer goal can be totally disassembled for removal and repositioning with various formed members being disconnected by the use of an efficiently designed connect / disconnect tool.

The invention discloses a detachable assembled high-ductility steel-concrete composite beam and belongs to the technical field of steel structures of structural engineering. A steel beam and a precast concrete floor are assembled through bolts. Bolt holes are reserved in the upper wing edge of the I-shaped steel beam, the bolts are pre-buried at the bottom of the precast concrete floor and welded or mechanically connected with transverse steel bars at the bottom, so that the ductility and the anti-collapse capability of the structure are improved under the action of a strong shock. During assembly, the precast concrete floor is built at the top of the upper wing edge of the I-shaped steel beam, the bolts pre-buried at the bottom of the precast concrete floor penetrate the bolt holes reserved at the upper wing edge of the steel beam, and then the steel beam and the floor are fastened by nuts. When the service life of the structure is up, the bolts are unscrewed and the precast floor and the steel beam are separated to realize disassembly. The novel composite beam has the advantages of a traditional cast-in-place composite beam, is simple in assembly construction, high in speed and low in cost, and can effectively prevent dust raising on a construction site; post-earthquake repair and replacement of damaged members are facilitated; and the detachable assembled high-ductility steel-concrete composite beam can be detached in the service period or after service termination, and has a wide engineering application prospect.
