Abstract: A rotary driver 1 for a helical pile foundation 2 attached to a boom arm 3 of an excavator 5 forming a counter-support is described by means of which the helical pile foundation 2 can be screwed into or out of the ground in a defined direction. The rotary driver 1 is supplied by the excavator 5 with appropriate power, preferably hydraulic power, and is arranged at the front end of the boom arm 3 of the excavator 5. A rotary drive 6 is provided for this purpose at the front end of the boom arm 3 which transmits a drive torque 11 to the helical pile foundation 2, for which purpose a chucking device 7 for the helical pile foundation 2 is provided at the end of the rotary drive 6 facing toward the helical pile foundation 2. An additional counter-support 4 is arranged on the rotary drive 6, on the front end of the boom arm 3, or on the chucking device 7 and is anchored in the ground at the end opposite the area of arrangement.

Abstract: The invention relates to a driving device, in particular a screw foundation driving device, having an anchor with a rotational axis for receiving a driving tool, an outer rotor, which is arranged concentrically to the rotational axis of the anchor and can be rotationally driven by a motor, and an impact device from which an impact energy can be introduced into the anchor. By means of rolling bodies arranged circumferentially on the anchor, the anchor is mounted in the outer rotor in such a way that a relative movement between the anchor and the outer rotor can be executed in the direction of the rotational axis and a torque about the rotational axis can be introduced from the outer rotor to the anchor via the rolling bearings.

Abstract: A method of reshaping a cylindrical pipe to a ground screw foundation for attaching an object to the ground includes a drawing unit and a working tool having a plurality of press roll disks or press roll disk segments. The press roll disks or press roll disk segments are disposed radially around a longitudinal axis of a holder for the cylindrical pipe, and pivotably around shafts extending at a fixed distance to the longitudinal axis transversely and tangentially relative to the longitudinal axis. A cylindrical pipe is inserted into a holder. The cylindrical pipe or the working tool with the drawing unit is drawn such that a relative movement between the pipe and the working tool is created.

In said method, a striking force is applied to the screwable foundation in the driving direction in alternation with or at least temporarily simultaneously with a torque when the screwable foundation is driven into the ground.

Abstract: An erection system for the attachment of solar panels arranged areally adjacent one another and inclined toward the sun. The solar panels are held in rows by a multiplicity of holding members that are fastened to posts anchored in the ground by base members arranged substantially orthogonally with respect to the holding members and which have downwardly open U-profiles. The base members can be connected to the posts via mounting units. Each mounting unit has two clamping shells with semicircular recesses for abutment against the posts and substantially planar abutment surfaces for abutment against the side surfaces of the U-profile. Bores are arranged in the abutment surfaces of the clamping shells and corresponding bores are arranged in the side surfaces of the base member such that the base members can be fixed in a frictionally locking and/or positively locking manner to the posts by screw connections extending through the bores.

Abstract: An apparatus for placing foundation devices and/or pipes and/or augers in the ground, as an attachment to be attached to the boom of a construction vehicle, including a mounting hinged to a coupling point of the boom, and a drive head, which is rigidly connected to the mounting and configured as a rotational driving and/or drilling and/or impact drilling and/or pile-driving drive and to which the foundation device/pipe/auger for placement in the ground can be coupled. The coupling point can be displaced with respect to the drive head in at least one first direction which is transverse to the longitudinal axis of the foundation device/pipe/auger, and optionally in a second direction, which is transverse to the first direction. The mounting can be a universal joint in which a first joint axis extends so that a first and a second joint part can be displaced thereon, relative to each other, in the first direction, so as to displace the coupling point.

Abstract: A method for varying the flight path of a missile, in particular of a spin-stabilized projectile, which has an outer wall and which is provided with at least one impulse device. The impulse device can be activated deliberately at a defined time during the flight of the missile. The impulse device is arranged with respect to the longitudinal axis of the missile such that, when it is activated, it generates an impulse that initiates a tumbling movement which causes the flight-path of the missile to be shortened or varied. A spin-stabilized projectile is provided with such an impulse device and it is configured so that the impulse device may be triggered during flight so as to initiate the flight-altering tumbling movement.

Abstract: A seeking fused munition (10), which at the front end thereof, has a projectile-forming insert (12). In order to define an optimally effective projectile-forming insert (12), even in a configuration of relatively small caliber, the seeking fused munition (10) is of a full-caliber configuration without a casing. A tail portion (24) is provided at the rear end of the seeking fused munition (10). The tail portion (24) is connected to the seeking fused munition (10) along a peripherally extending specified rupture portion (26).

Abstract: In a rotary drive for rotating a panel-shaped solar module, rotary pulses with a limited rotational path are introduced from outside only by step. A rotatable gear disk in the rotary drive has a regularly ratcheted control contour with ratchet units like teeth. In cooperation with a control member, what this attains is that the rotatable gear disk returns to a defined stable starting/center position when rotating up to a limiting angle, but when the limiting angle is exceeded advances at least one ratchet unit. The solar module is connected rotation-fast to the gear disk. What this embodiment attains is that the positioning accuracy of the solar module is largely independent of the rotary pulse introduced from outside. This means that a group of rotary drives can be rotated jointly with a central drive via mechanical coupling links, and despite the inaccuracies of a mechanical coupling there is good and uniform positioning accuracy for the individual solar modules.

Abstract: A method for manufacturing a device for fastening poles, posts, masts or the like in the ground and a fastening device with a basic body are described, it being possible, but not essential, for at least one part portion of the basic body to be provided with a screw-like or spiral-like thread, and the basic body essentially having a cone-shaped basic shape with at least one conical part portion. According to the method of the present invention, the basic body is hammered into the basic shape from an essentially cylindrical tube. The fastening device has a holding portion, and an anchoring portion designed in one piece which, if provided with a thread, has at least two part portions of different conicity. The holding portion and essentially the anchoring portion are hollow throughout.
