Abstract: A pipe clamp is formed of a pair of semicircular clamp halves, one having a first end region (1) and the other a second end region (2). First end region (1) has a radially outwardly extending projection (3) and two guides (6, 7) located along opposite sides. Second end region (2) has a circumferentially extending radially flexural locking strip (4) with a stop face (5) directed away from a free end of the second end region (2). In the closed position, the guides (6,7) of the first end region overlap at least a part of the second end region, so that the second end region is prevented from moving radially outwardly. In moving the first and second end regions into the closed position, the projection presses the locking strip radially outwardly until the projection (3) cooperates with the stop face (5) of the locking strip (4) in the closed position.

Abstract: A pipe clamp includes a wall part (1) with at least one bracket (3) located on its outside surface. At least one attachment part (2) is engageable in the bracket (3) and projects laterally outwardly from the wall part.

Abstract: An apparatus for mixing at least one flowable mass includes a rotatable support (2), a container carrier (1) and container (4) and a separate housing (3). The container carrier (1) and housing (3) each has a central axis inclined relative to the axis of the rotatable support (2). The container carrier (1) can be driven around its axis opposite to the rotational direction of the rotatable support (2). The apparatus is balanced by an equalizing mass (3a) in the housing (3) disposed diametrically opposite the container carrier (1).

Abstract: A tool for placing and securing sealing strip (11) into a joint gap (19) between structural parts (17, 18) includes a lead-in device (10) guiding the sealing strip (11) into the joint gap (19), an insertion device (8) aligning the sealing strip (11) and a contact pressure device (7) with two coextensive contact pressure faces (12, 13) for pressing the sealing strip (11) within the joint gap (19). A spacing (A) between the contact pressure faces (12, 13) transversely of their coextension is variable.

Abstract: A drilling or chiseling tool (1) includes a suction device (2) with a suction head (3), a suction line (4) extending from the suction head to a suction blower wheel (5) and a separating device (6). The suction device (2) is detachably connected with the tool (1). When connecting the suction device (2) to the tool (1), the shaft (9) of the suction blower wheel (5) can be coupled with the drive shaft (8) of a drive motor (7) for the tool.

Abstract: A portable hand-held tool, such as a hammer drill or chisel hammer, includes a housing having a main vibration axis and a handle displaceably secured to the housing and movable toward the housing against compression springs. The springs have an axis of compression disposed at an angle to the main vibration axis. When the handle is displaced toward the housing, the spring is compressed. At the same time, however, the increased force of the spring is compensated by the increase in the angle of the spring relative to the main vibration axis. As a result, though the spring force increases, its component acting in the main vibration axis direction is reduced, and the spring force acting in the main vibration axis direction remains constant.
