Abstract: The invention relates to a pipe connection (10, 52, 66) with a first pipe part (12) and a second pipe part (14), with at least one multi-part sealing ring (24; 44, 46) or at least one single-part sealing ring (68) which is surrounded by a clamping device (16). The pipe parts (12, 14) each comprise a first obliquely or vertically extending end face (20, 72) or a second obliquely or vertically extending end face (22, 74). These are overlapped by a clamping device (16). This applies an outwardly acting radial force (34) to the at least one single-part sealing ring (68) or the at least one multi-part sealing ring (24; 44, 46). These are secured in their respective sealing position by means of an enclosing geometric triangle, by means of an enclosing geometric non-rectangular quadrilateral (104) or by means of an enclosing geometric rectangular quadrilateral (106).

Abstract: The invention relates to a multipart pipe joint (10) having a centre piece (16) on which joint parts (18, 20) are received which are pivotable relative thereto and which are rotationally fixed to the centre piece (16) at articulation points (22, 24). The articulation points (22, 24) of the joint parts (18, 20) on the centre piece (16) also represent articulation points (22, 24) for transmission elements (42) which extend axially along an inner wall (34) of the centre piece (16). The articulation points (22, 24) forming articulation axes are arranged in an axial offset (25) to each other. Furthermore, the invention relates to the use of the multipart pipe joint (10) in an aircraft.

Abstract: The invention relates to a device for connecting pipe ends (80, 82) of double-walled pipes (72, 74) for angular compensation and for length compensation of the relative movements of the double-walled pipes (72, 74) relative to a double-walled connector (10). On the double-walled connector (10), there are arranged concentrically with respect to one another first and second ball heads (20, 26). These are each sealingly engaged over by ball cages (52, 54). The ball cages (52, 54) are formed on double-walled attachments (46) of the double-walled pipe ends (80, 82). The sealing function for double-walled angular compensation and double-walled length compensation are configured so as to be decoupled from one another, and are therefore optimized, in the case of the device proposed according to the invention.

Abstract: A computer implemented method for planning an object which comprises a multitude of single parts and subassemblies, especially an aerospace object, the method comprising: calculating the total weights of the subassemblies and/or of the object on the basis of the data sets of the single parts and the subassemblies, wherein measured weights are used preferably to calculated weights, and calculated weights are used preferably to target weights for the calculation of the total weight(s) of the subassemblies and/or of the object, and calculating and providing the information about the shares of the used weight types in the calculated total weights. The invention further also relates to a manufacturing system and a computer implemented construction module.

Abstract: The invention relates to a cargo-hold floor for aircraft which is received on a grid structure (1). The grid structure (1) comprises essentially longitudinal members (2) and crossmembers (3). Exchangeably arranged floor plates (80), furthermore roller conveyor apparatuses (50) and lashing points (10) for the fastening of cargo articles, such as pallets, containers or vehicles, are received on the grid structure (1). Furthermore, locking units (98) are provided, which comprise lock elements (100) capable of being folded open and of being folded away. The lashing points (10) are located at the intersection points of the longitudinal members (2) and of the crossmembers (3). The roller conveyor apparatuses (50) and the locking units (98) are always located at the same installation location both in their erected position and in their countersunk drive-over and stowage position.

Abstract: The invention relates to a transporting roller with a drive unit assigned thereto, wherein the transporting roller (1) has a circumferential surface area (2) of an elastic material (18, 19, 20). The transporting roller (1) rotates about an axis of rotation (3) and is accommodated in the housing (17) of the drive unit. The transporting roller (1) contains at least one colored marking body (11), which is visible in the circumferential surface area (2), is composed of an elastic material and the abrasion properties of which correspond to those possessed by the elastic material (18, 19, 20) of the circumferential surface area.

Abstract: The invention relates to a method of positioning items of freight or freight containers (3) on a floor surface (51) of a hold having conveyor tracks (41, 41a) integrated into the floor surface (51) and drive units (47, 48) let into the floor surface (51). Items of freight or freight containers (3) pass over first guide elements (1) assigned to the conveyor tracks (41, 41a) and accommodating sliding bodies (70) in a first direction (43) or a second direction (42) and are aligned, on second guide elements (30) containing sliding bodies (70), in the first or second direction between the first guide element (1) and the second guide element (30). The aligned items of freight or freight containers (3) are then guided into one or more storage spaces (64, 63; 66, 65) of an additional storage area region (53) in the second direction (42) or opposite thereto.
