Abstract:
A window covering (10) includes at least one pair of cell-supporting cords comprising a first support cord (50) supporting an upper portion of each cell (16) and a second support cord (54) supporting a lower portion of each cell. The collapse and expansion of each cell is accomplished by the respective raising and lowering of the second support cord without movement of the first support cord.

Abstract:
There is described a manufacturing method of motor vehicles which achieves the object of reducing the costs deriving from the manufacturing of vehicles belonging to different segments and the costs deriving from the traditional assembly of vehicles which starts from the external shell onto which the elements forming the interiors and the mechanical members are assembled, by suggesting the arrangement of a single self-supporting structural element formed by composite material, already provided with many interior elements, to which a new other interior elements, bodywork elements and mechanical elements can be connected in any assembly order.
Abstract:
Methods and systems to manufacture lattice-based sandwich structures from monolithic material. Such methods and systems eliminate the bonding process which is conventionally used to join lattice based truss cores to facesheets to form sandwich structures. This bonded interface is a key mode of failure for sandwich structures which are subjected to shear or bending loads because the nodes transfer forces from the face sheets to the core members while the topology for a given core relative density dictates the load carrying capacity (assuming adequate node-bond strength exists). An aspect comprises a core and related structures that provide very low density, good crush resistance and high in-plane shear resistance. An aspect of the truss structures may include sandwich panel cores and lattice truss topology that may be designed to efficiently support panel bending loads while maintaining an open topology that facilitates multifunctional applications.

Abstract:
A rib post (10) has a hollow substantially triangular cross-section comprising composite material. The rib post (10) can form a structural member to join two adjacently placed components together, for example a spar and internal rib in a wing of an aircraft. The rib post (10) can be formed from first (12), second (14) and third (16) walls. The first wall (12) can abut a surface of one component and the second wall (14) can abut a surface of a second component. The first and second walls (12, 14) can be attached to the respective components, such as a rib and spar, to join them together. The third wall (16) joins together the first and second walls (12, 14) to form the hollow triangular section.
Abstract:
In a locking element (5) for a fixing system (3) for quadrangular plate-shaped panels (1, 2) and comprising an insertion portion (6) for insertion into a locking groove (7) provided in the longitudinal direction of an edge of a first panel (1) and a locking portion (8) for engagement into a latching recess (10) of an undercut configuration provided in a laid configuration of the panels (1, 2) in an opposite edge of a second panel (2) and extending in the longitudinal direction of said edge and in opposite relationship to the locking groove (7), wherein the locking portion (8) includes a resilient latching tongue (9) which during assembly of the two panels (1, 2) is automatically latchable into the latching recess (10) into a latching position, the locking element (5) has anchoring means (18) and the locking element (5) can be captively anchored by the anchoring means (18) with its insertion portion (6) in the locking groove (7). The invention concerns also: a panel with holding profiles (4.1, 4.2) and an additional automatically latching locking element,- methods of locking quadrangular panels; and a method of automatically mounting a locking element to an edge of a panel well as an apparatus therefor.
