Abstract: The present invention relates to a method for manufacturing an adhesive bond between two components, in which an adhesive is used that can be cured with at least two different curing mechanisms. A first curing mechanism here generates less stiffness in the adhesive than at least one second curing mechanism. The layer of adhesive applied to join the components is cured with the first curing mechanism in the region between the components over the entire layer and with the at least second curing mechanism only locally, so that the stiffness of the adhesive layer varies in the region between the components. In like manner, a composite or composite layer can be manufactured with a matrix material, in which the matrix material is varyingly locally cured. The invention also relates to an adhesive or matrix material suitable for the method. The material and accompanying method can be used for many applications.

Abstract: The invention relates to a method for recording a characteristic of at least one object (28, 56, 68). According to the invention, a) a luminous radiation that is influenced by the object (28, 56, 68) is fed to an image sensor (6), b) at least two different partial images (32, 34, 36, 48, 78, 90, 94, T1, T2) consisting of pixels (26) are read out in succession from the image sensor (A11, A12, A13, A21) and values assigned to the pixels (26) are fed to an evaluation unit (10), c) the respective characteristic (B11, B12, B13, B21) of the object is determined from the values that are assigned to a partial image (32, 34, 36, 48, 78, 90, 94, T1, T2), d) the partial images (32, 34, 36, 48, 78, 90, 94, T1, T2) are combined to form a total image (38), which is output for further processing.

Abstract: A method of manufacturing of an expansion sleeve including providing a sleeve blank having axially extending material weaknesses (9), and forming the longitudinal slots (5) by tearing open the material weaknesses (9) by substantially radially expanding same.

Abstract: An expansion dowel having a cylindrical expansion body (1) having a through-bore (3) and formed of at least two segments (4a, 4b) connected with each other, an additional expansion element (7) located in a recess (8) formed in an outer profile (6) of the expansion member (1) and having a radial depth of the recess (8) diminishing in a setting direction (S) of the expansion dowel; the additional expansion element (7) having a radial extent at least partially greater than a maximal dept of the recess (8).

Abstract: An expansion dowel formed of an expansion sleeve (1) slotted at least along a portion of its longitudinal extent, starting from an end of the expansion sleeve (1) facing in a setting direction (S) of the expansion dowel, and an expansion member (2) formed of at least two segments (7, 8), receivable in the through-bore (3) of the expansion sleeve (1), and having an outer profile (6) widening in the setting direction (5) for expanding the expansion sleeve (1) and a bore (4) provided with an inner thread (5).

Abstract: An expansion dowel having a cylindrical expansion body (1) having a through-bore (3) and formed of at least two segments (4a, 4b) connected with each other, an additional expansion element (7) located in a recess (8) formed in an outer profile (6) of the expansion member (1) and having a radial depth of the recess (8) diminishing in a setting direction (S) of the expansion dowel; the additional expansion element (7) having a radial extent at least partially greater than a maximal dept of the recess (8).

Abstract: An anchor bolt having a substantially cylindrical stem (2), and at least one thread provided on the stem (2) and extending from a free front end of the stem at least over a portion of a longitudinal extent of the stem (2), the thread (6) having a plurality of thread turns (6) having, at least over one/third of the stem (2), a width (b1, b2) which decreases, with an increase of a distance of a respective thread turn (6) from the free front end of the stem (2), so that a distance (x1, x2, x3) between trailing and leading flanks (8, 7) of two following one another thread turns (6) of the thread increases backwards.

Abstract: An expansion dowel has an expansion sleeve (7) insertable into an axially extending dowel body (1) which has a central through opening (2) and a collar (6). The leading end region (3) of the dowel body (1) in the setting direction (S) has an internal thread (8) acting as a load application means, and the oppositely located, trailing end region (4) has at least one axially extending slit (5), and serves to receive the expansion sleeve (7). Due to the fact that there is at least one joint arranged in the leading end region (3) of the dowel body (1) adjoining the internal thread (8), a threaded rod (10) can be inserted up to the desired position in the through opening (2) by a slight axial pressure in the setting direction (S).

Abstract: An attachment element for an anchor rod (14) including a substantially cylindrical expansion member (1) having an axial bore (8), and one-piece expandable member (2) extending, at least partially, into the axial bore (8) of the expansion member (1) without a possibility of disengagement from the expansion member (1) and having, at least along a portion of its longitudinal extent, a conical section tapering in a direction opposite to a setting direction (S) of the anchor rod (14), an axial bore (4), and at least two elongate slots (11).

Abstract: A shaped part having a hollow cylindrical body (1) having at least two longitudinal slots (5) extending over a larger portion of a longitudinal extent of the hollow cylindrical body (1) and open at one of end surfaces of the hollow cylindrical body (1), and a circumferential undercut formed in an inner wall (3) of the hollow cylindrical body (1) in its longitudinal region intersected by the longitudinal slots (5), spaced from the one end surface, and having a flank (9) tapering toward the one end.
