Abstract: The invention relates to a computer-implemented method for operating a database comprising the step of updating a binary status of a tuple in the database. The binary status field either contains a null value or a time stamp. The update can be done in-place or by using an insert-only approach.

Abstract: An adjustment device aligns supporting parts that pivotally accommodate the guide rails of a freight loading system on structures having inherent dimensional tolerances. The structures can in particular be in an aircraft fuselage. Each supporting part is designed as a bearing insert that can be inserted in a bearing eye of a bearing block such that it cannot rotate. Each bearing insert has fitting surface sections separated from one another by planes of symmetry. Each bearing insert has at least one asymmetrically arranged axis accommodation.

Abstract: In an adjustment device for the alignment of supporting parts on structures having inherent dimensional tolerances, in particular in an aircraft fuselage, by means of joining surfaces, the joining surfaces form positive shapes and negative shapes corresponding with one another in a form fit. The positive shapes and the negative shapes in each case are arranged in a cross grid.

Abstract: In one embodiment the present invention includes a relational database management system component and a column-oriented data processing component. The relational database system component stores database information in a row format. The column-oriented data processing component stores the database information in a column format. In response to a database update request, the relational database management system component updates the database information stored in the row format; the relational database management system component notifies the column-oriented data processing component of the database update request; and the column-oriented data processing component updates the database information stored in said column format. In response to a query request, the column-oriented data processing component generates a query response based on the database information stored in said column format.

Abstract: The invention relates to a rotating, disc-shaped, agricultural tool which is mounted in a frame of a machine via a hub and a bearing arrangement. The bearing arrangement is distinguished by the fact that it is formed from two angular roller bearings which are set in back-to-back arrangement and whose raceways are arranged inclined at an angle to a bearing axis, wherein a space accommodation the angular roller bearings is defined on the outside in the radial direction by a hub body, of V-shaped design in its centre part and having contact surfaces, and on the inside in the radial direction by a supporting ring having spaced-apart contact surfaces on both sides in the axial direction, wherein the hub body is provided at an axial end with a fastening element for fastening the tool. In this way, a captive bearing unit is provided which is already provided with the appropriate prestress and which only needs to be connected to the agricultural tool and to the frame by the end user, i.e.

Abstract: A loading device for cargo spaces in transportation means, in particular for cargo spaces in aircraft, includes a roller conveyor that contacts a substructure in a first position for placing cargo units in the cargo space. In one embodiment, the roller conveyor has contact surfaces on both sides and the substructure 3 is formed as a U-profile having a base and two webs. Both webs of the U-profile have bearing surfaces oriented at least partially inwardly and the contact surfaces are formed, such that they cooperate with the bearing surfaces in the first position and in a second position. In the second position, the roller conveyer 2 is insertable into the substructure for forming a substantially flat base surface of the cargo chamber, which serves in particular for placing vehicles into a cargo space.

Abstract: The invention relates to a loading device 1 for cargo spaces in transportation means, in particular for cargo spaces in aircraft, with a roller conveyor 2 that contacts a substructure 3 in a first position for placing cargo units in the cargo space. According to the present invention, the roller conveyor 2 has contact surfaces 34-37 on both sides and the substructure 3 is formed as a U-profile, whereby both webs 23, 24 of the U-profile have bearing surfaces 25, 26 oriented at least partially inwardly and the contact surfaces 34-37 are formed, such that they cooperate with the bearing surfaces 25, 26 in the first position and in a second position, in which the roller conveyer 2 is insertable into the substructure 3 for forming an essentially flat base surface 14 of the cargo chamber, which serves in particular for placing vehicles into the cargo space.

Abstract: A mold closing device for an injection molding machine for plastics includes a movable tool clamping plate having a first side opposedly oriented to a fixed tool clamping plate for cooperatively mating tool halves with the fixed tool clamping plate and having a second side distal from the fixed tool clamping plate. The movable tool clamping plate is mounted on a machine slide connected to a first and second guide shoe for traversing in an axial direction two guide rails associated with a respective edge of the movable tool clamping plate. The mold closing device also includes two bending elements. Each of the two bending elements connects a corner of the second side of the movable tool clamping plate to a guide shoe that is cooperating with one of the at least two guide rails. Each bending element is rigid perpendicular to the respective guide rail and includes a bending region that has a predeterminable elasticity in the axial direction to absorb a closing force.

Abstract: A test device for testing an electronic board assembly with an exposed surface area with electrical connection locations to be contacted for testing includes a probe (32, 45) and a drive system for positioning the probe in orthogonal X and Y directions parallel with the surface area. The drive system includes a probe drive (11) for positioning the probe to contact a selected sub-area of the surface area, the probe drive being movable in all movement coordinates independently of any other probe drives in said test device. The sub-area is selected to include component locations (34) on the board assembly. Several probe drives (11) and several probes can be used at one time, each drive having a probe (13). The probe drives are supported so that the probes (13) can be moved to contact sub-areas adjacent to each other. The probe is an elongated needle with a contact tip and is mounted for pivotal movement.

Abstract: The invention concerns a test device for electronic board assemblies, said device comprising at least one probe which can be positioned parallel to the surface within the total area of an assembly by drive devices. The test device is characterized in that the drive devices comprise a probe drive which, operating in all directions of movement independently of other probe drives, positions the probe on a sub-area of the total area.

Abstract: Process and device to spool longitudinally cut partial sheets from a material sheet having a sheet width. The process may include forming a spooling roll from each partial sheet such that the formed spooling rolls rest on at least two spooling beds including individually motorized spooling-support rolls. During at least a beginning of the spooling process, the process also may include pressing at least one of the spooling rolls being formed against its respective spooling bed with a loading roll, positioning the at least one spooling roll with the loading roll in a middle portion of sheet width, and motorizing the loading roll independently of the support rolls to initiate an adjustable portion of a turning moment exerted onto the at least one spooling roll.
