A nacelle of a wind turbine is disclosed. The nacelle comprises a rear frame structure (1) comprising a plurality of truss assemblies (2) being connected to each other at connecting regions (3). At least one of the truss assemblies (2) comprises at least one beam structure (4), the beam structure (4) comprising at 5 least a first beam member (5) and a second beam member (6) being arranged substantially in parallel to each other, thereby defining a longitudinal direction of the beam structure (4). The first (5) and the second (6) beam members are retained to each other by a retaining means (12). The retaining means (12) is configured to enable the first beam member (5) to slide relative to the second 10 beam member (6) along the longitudinal direction, e.g. by means of oblong slits (11) formed in the first beam members (5) and bolts (12) extending through the oblong slits (11) and being attached to the second beam members (6).

The invention concerns a truss structure including a plurality of longitudinal members extending parallel to one another in a main extension direction and crossmembers (9) distributed in the main extension direction to connect the longitudinal members mechanically two-by-two, forming a plurality of polygons (11) each contained in a plane perpendicular to the main extension direction.

According to the invention, each crossmember (9) connecting two longitudinal members includes a first half-crossmember (9a) with a first end connected to one of the two longitudinal members so as to be able to pivot about a first axis (X1-X′1) and a second half-crossmember (9b) a first end of which is connected to the other of the two longitudinal members so as to be able to pivot about a second axis (X2-X′2). The two half-crossmembers are connected to one another by an articulation hinge (13) allowing relative rotation of the two half-crossmembers (9a, 9b) about a third axis (X3-X′3). The first, second and third axes are parallel to one another and orthogonal to the main extension direction, allowing the truss structure and each crossmember (9) to pass from a deployed position to a folded position in which the first and the second half-crossmembers (9a, 9b) of each crossmember (9) extend substantially parallel one alongside the other in said main extension direction.

A deformable device includes a deformable beam or hinge having an extended state, a flattened state, and a rolled state if a beam, where a stiffness and strength in the extended state is greater than a different stiffness and strength in the flattened state, the deformable beam or the hinge deformable along a long axis. An end face cross section transverse to the long axis includes a first periodic curved member which defines at least two shaped curves. A second periodic curved member defines at least two shaped curves. The second periodic curved member is mechanically coupled to the first periodic curved member at respective ends of the end face cross section. The first arc length of the first periodic curved member and the second arc length of the second periodic curved member are of about a same arc length.

Aspects of the disclosure relate to a truss with integrated wiring. A truss with integrated wiring includes a plurality of chords coupled together with a plurality of support members. At least one chord of the plurality of chords includes a hollow space along a length of the at least one chord of the plurality of chords. The truss with integrated wiring further includes a first set of electrical connectors situated near a first end of the at least one chord of the plurality of chords, and a second set of electrical connectors situated near a second end of the at least one chord of the plurality of chords. The first and second set of electrical connectors are outside of the hollow space. The first set of electrical connectors is coupled to the second set of electrical connectors through a set of electrical wires housed in the hollow space.

A framework includes at least three posts, and at least three connecting ribs between the posts. First ends of the posts define a first plane, and second ends of the posts, that are opposite to the first ends thereof, define a second plane. At least one of the posts is adjustable to define, in combination with a further post of the at least three posts and two connecting ribs between the adjustable post and the further post, an adjustable trapezium that is configured to set a relative orientation between the first plane and the second plane and to thereby set an orientation of an adjoining framework. A system in which a plurality of said frameworks are interconnected.

An example of support member is provided. The support member includes a plurality of elongated members connected to form a first elongated rigid structure. In addition, the support member includes a first elongated member of the plurality of elongated members disposed proximate to a first edge of the first elongated rigid structure with a first member top surface. The support member further includes a first stacking guide disposed on the first elongated member wherein a first attachment top surface is to slope toward the first member top surface. Also, the support member includes a second elongated member of the plurality of elongated members disposed proximate to a second edge of the first elongated rigid structure with a second member top surface. The second edge is opposite the first edge. The support member also includes a second stacking guide disposed on the second elongated member.

Improvements are disclosed in the ordering, preparation, billing, and delivery of food and beverages in contexts including retail establishments. The customer order can be developed at the same or another location, via an application on a smartphone, tablet, or computer, on or offline. Various factors that allow predicting the details of a customer's probable order simplify the process. Automatic allow for polling other parties who might have their own interest in similar products, and the aggregation of such interest in a common order. Orders are transferred to systems in the establishment that streamline ordering, billing, preparation, and customer pickup of completed items.

A rotatable forkend connection system is provided that includes a shank and a forkend connector. The shank is fixedly coupled to a device member and extends within the device member along a longitudinal axis of the device member. The shank includes a protrusion extending from the shank in a direction perpendicular to the longitudinal axis of the device member. The forkend connector is rotatably coupled to the shank and has an axis of rotation coaxial with the longitudinal axis of the device member. The forkend connector includes a recess configured to receive the protrusion. The protrusion and the recess are configured to restrain the forkend connector from moving along the longitudinal axis of the device member.
