Abstract: A grinding or polishing brush is provided and includes a main body which is rotatable about a central axis and is provided with bristles which extend with their center axes substantially in the direction of the central axis. In order, with such brushes, to permit pin point working, it is proposed that the center axes of the bristles have an inclination in the circumferential direction and/or inward in the radial direction. The effect which can therefore be achieved with the bristles is that they are supported against one another. In order to improve this, the bristles can be provided in an axial portion with film elements connecting them. The film elements may be able to come apart depending on wear.

Abstract: A method for producing an inflatable lifting cushion includes providing a core with main surfaces in the form of a front side and a rear side and an outer peripheral region. A two-dimensional layer of vulcanizable material is applied on the front side and rear side of the core. A single-layer or multi-layer prefabricated two-dimensional fiber-reinforcing layer is drawn in the form of a tube, onto the arrangement including the core and two-dimensional layers of vulcanizable material located on the core so that the fiber-reinforcing layer, extending around the peripheral region, covers the two-dimensional layers of vulcanizable material at least partially. A further two-dimensional layer of vulcanizable material is applied to the fiber-reinforcing layer at the front side and the rear side of the core. The arrangement is heated to obtain a bond of the fibers of the fiber-reinforcing layer with the two-dimensional layers of the vulcanizable material.

Abstract: A pump unit (10) can be carried by an operating person for the pressurized filling of inflatable filling chambers with a fluid, in particular lifting pads (2), blocking pads, tents or the like. The pump unite includes a fluid pump (12), an electric motor (11) for driving the fluid pump (12), a battery (13), a control unit (17) for controlling the operation of the fluid pump, and a connector (18) for the connection of a fluid hose (3) which leads to the filling chamber. A manually actuatable control valve (16) is positioned on the pump unit (10).

Abstract: A radial brush includes a disk-shaped central body and a plurality of bristles which extend away from the central body in the radial direction. The brush is embodied in such a way that, in a region adjacent to the central body in the radial direction, bristles arranged next to one another have a dividable connection to one another over a radially extending portion.

Abstract: The lifting bag comprises an inside bladder (20) having a nipple (22), and a shell (24) of reinforced rubber material located outside of the inside bladder (20) and closely enclosing the inside bladder (20). The shell (24) comprises a passage for the nipple (22). The inside bladder (20) is produced in a first vulcanizing step; the shell (24) is added and is produced in a subsequent second vulcanizing step. A separating material (26) is located between the shell (24) and the inside bladder (20); the shell (24) is not connected with the inside bladder (20). A method for producing such a lifting bag is provided.

Abstract: A filing device produced as a continuous one-piece body from a sheet or foil by a punching - stamping process has sequencing tongues supported as bending-elastic compression members moving easily with the folding movements of the file covers in insert strips and which are provided with locking members for easily detachable locking in their fastening position. This avoids bending of the sequencing tongues when closing the file covers and the sheets of the fastened sheet layers can be easily turned over and back along the sequencing tongues without the latter accidentally sliding out of the insert strips.
