Abstract: A fastening system including a plurality of fastening modules to mount a solar module having a first longitudinal direction on a roof structure or a façade having a second longitudinal direction. Each fastening module comprises one module carrier mountable on the roof structure or on the façade; a slide block guidable inside the module carrier; a module clamp; and a fastener to connect the module clamp to the slide block to clamp a respective solar module between the module clamp and the slide block. The module clamp is rotatable between two positions on the fastener so that an arrangement of the fastening modules permits the solar module to be mounted on the roof structure or the façade with the first longitudinal axis perpendicular or parallel to the second direction.

Abstract: A support arrangement for a solar module includes a post having a first surface section. A support structure includes a connecting element presenting a second surface section facing the first surface section in a direction of a joint surface normal of the first and second surface sections. A stop element is arranged in the surface normal direction offset to the first and second surface sections. A first form-fitting connection exists between the stop element and the post and a second form-fitting connection exists between the stop element and the connecting element, providing vertical support of the connecting element relative to the post. The first and second form-fitting connections are producible at different heights of the connecting element relative to the post. A fastening element holds in place the first surface section and the second surface section relative to each other in the direction of the joint surface normal.

Abstract: The invention relates to computer-implemented methods and systems for providing comments within source code. For providing access management to the comments, in one aspect, the comments are stored separately from the source code, the comments are retrieved from the storage medium, and the retrieved comments are displayed with the source code. In certain aspects, filter information may be stored with one or more comments and the comments may be provided based on filter information. The filter information may be used to block a requesting user from having access to certain comments. Access authorization information may also be used to control access to the comment information.

Abstract: A rock drill has an axially elongated shank (1) with a hard metal drill head (2) secured at one end. The transverse cross-section of the drill head is basically rectangular with cutters located along each of two diagonals of its cross-section. The cutters remove drillings from rock. The cutters include a main cutter (4) and two auxiliary cutters (5, 6) having the same rotational envelope curve.
