Abstract: An electronic control device assists in the insertion of an implant into the body of a patient, and allows the implant to be arbitrarily altered in shape by applying control signals. Patient-specific geometric body data from a body region into which the implant is to be introduced is input and stored. Computer-aided simulation of the insertion operation uses the patient-specific body data as a basis for simulating the insertion operation to produce actuation data which control the arbitrary alteration in the shape of the implant. The control device outputs the actuation data to the implant in the form of control signals on the basis of a sensed or calculated current introduction position of the implant according to the prior simulation.

Abstract: Disclosed is a device for cleaning wheel rims. Said device is used for removing sticky excess powdered pigments from the flange and hub of the rims prior to the baking process during powder coating. The inventive device comprises a first brush which can be introduced into the hub of a rim that is to be cleaned as well as a second brush which is concentrically disposed around the first brush and rests against the flange surface of the rim when the first brush is inserted in the hub of the rim. The first brush can be axially displaced relative to the second brush and is spring-mounted on the second brush. Furthermore, a drive unit is provided which rotates the first and the second brush by a specific angle, respectively.

Abstract: A handling device for handling a motor vehicle rim in an installation for its surface treatment has at least one gripping arm which can be inserted into a hub of the rim and carries at least one pressure element which can be pressed against an inner surface of the hub. According to the invention, the at least one pressure element is designed as a cutting edge or as a pointed peg.

Abstract: A handling device for handling a motor vehicle rim (11) in an installation for its surface treatment has at least one gripping arm (12) which can be inserted into a hub (26) of the rim (11) and carries at least one pressure element which can be pressed against an inner surface (28) of the hub (26). According to the invention, the at least one pressure element (18) is designed as a cutting edge or as a pointed peg.

Abstract: The invention includes a mount having an input side attachment member and a plurality of isolation pads positioned within the input side attachment member. At least two of the pads have different performance characteristics. The invention further includes an output side attachment member positioned within the input side attachment member and one or more of the pads are post-vulcanization bonded to at least one of the input side attachment member and the output side attachment member.

Abstract: A method for forming a hollow body during which, for the purpose of impression of internal stresses, the body is subjected during its production to axial forces and moments. For this purpose the hollow body is supported from the inside by a mandrel constituted by disks which can move relative to one another and which, accordingly, do not obstruct axial expansion and twisting of the hollow body.

Abstract: In order to increase resistance to fatigue which is decreased by crack formation in at least one fiber layer of a torsion-stressed component part, an intermediate layer of a material which is soft relative to the fiber layers is arranged between individual fiber layers.

Abstract: In order to impress internal strains in fiber-reinforced plastic layers of a torsion-stressed component part, a gap or crack is produced in at least one of the layers by applying forces to the component part and filling the crack with a material during the application of the forces. After the forces are removed, the filled crack cannot close, thereby creating internal strains.

Abstract: In this method of fabricating a hollow body, a first layer of fiber-reinforced hard-elastic plastic is formed to produce an inner layer of the hollow body with the fibers of the fiber-reinforced hard-elastic plastic extending skew to the longitudinal axis of the hollow body within a predetermined range of fiber orientation angles. A second outer layer of fiber-reinforced hard-elastic plastic is formed around the inner layer with the fibers oriented in a predetermined different range of fiber orientation angles. At least one of the layers is heated to a desired elevated temperature. At least one of the layers is subjected to a predetermined force or combination of forces. The hollow body is then cooled to the hard-elastic state, locking internal stresses into the two layers when the applied forces are removed.

Abstract: Apparatus and a method are disclosed for replenishing an electroless plating bath with those of its components which are consumed during plating operation, in order that the concentration of components be maintained as nearly constant as possible in the working bath. The system involves withdrawing from the bath a small sample stream at fixed rate, and subjecting this automatically to a sequence of analyses. The system is particularly adapted to control of electroless copper solutions comprising copper ion, hydroxide and formaldehyde as the consumable components. Sequential analyses are made of the sample stream for these components using instrumentation to control actuators which introduce replenisher solutions into the plating tank in response to signals generated by the instruments whenever deviation occurs from a pre-set level. Standardized test solutions of known concentration and rate of feed are introduced into the test stream to optomize test conditions during the analyses.
