  • Patent number: 8060239
    Abstract: According to the invention, an initial trajectory (2) that is to be followed in a positionally guided manner is input into a computer (15), said initial trajectory (2) being described by an initial function (AF) such that one respective corresponding position (pA) is determined on the initial trajectory (2) by substituting a scalar trajectory parameter (s) into the initial function (AF). The scalar trajectory parameter (s) is different from time (t) while being characteristic of a distance (s) covered along the initial trajectory (2). The computer (15) filters the initial trajectory (2) with low-pass characteristics referring to the scalar trajectory parameter (s) as a function of the scalar trajectory parameter (s) and thus determines a rough function (GF) such that one respective corresponding position (pG) is determined on the rough trajectory (13) by substituting the scalar trajectory parameter (s) into the rough function (GF).

  • Patent number: 8043681
    Abstract: In a method of making a hybrid structure, at least one support body is fixed in a tube component which is then placed in an injection molding tool. An injection-molded part is injection-molded to an outer surface of the tube component in an area of the support body. As a result, the tube component is inwardly deformed, when regions adjacent to the support body are exposed to an injection pressure, and forms indentations for engagement of the injection-molded part.

  • Patent number: 8040017
    Abstract: A piezo actuator includes an adaptation element, which is configured to adapt the piezo actuator to a controller for inductive loads, particularly to a converter for actuating inductive loads. The adaptation element allows use of controllers or converters of numerical control systems, which normally are used for actuating servo motors. Therefore it is no longer necessary to provide specially designed hardware for the actuation of piezo actuators, but instead the above-mentioned controllers can be used. Furthermore, as a result of the adaptation element, the piezo actuators can be integrated in the bus of the numerical control system. This allows communication in real time via the NC bus.

  • Patent number: 8026687
    Abstract: A machine having a drive that directly or indirectly excites vibrations in the machine over a frequency range when the drive is connected to the power supply. A sensor detects a time-dependent signal that is characteristic of the excited vibrations. The time-dependent signal is transmitted to a control device that analyzes the frequency of the time-dependent signal and relates the frequency analysis to the excitation that produces the excitation and uses this relationship to determine a state of at least one element of the machine. The control device outputs a message to an operator of the machine on the basis of the state that is determined. Preferably, the control device applies an interference variable that has at least one frequency inside the frequency range to the drive so as to excite vibrations. The interference variable may be a sinusoidal interference variable whose frequency passes through the frequency range, or a pseudobinary interference variable whose spectrum covers the frequency range.

  • Patent number: 8026643
    Abstract: The invention relates to an electrical machine with an internally cooled rotor. In order to improve the cooling power of such a machine without the use of a fan wheel fitted separately on the rotor, the invention proposes an electrical machine with a stator laminate stack and a rotor in a housing, which electrical machine has an internal cooling circuit comprising rotor cooling channels, which pass axially through the rotor and are arranged on two concentric circles, in which internal cooling circuit a gaseous coolant can be circulated, wherein fan vanes and a first means for guiding the coolant from the rotor cooling channels on one of the two concentric circles via a winding head to the rotor cooling channels on the other of the two concentric circles are provided in the case of the machine on a first rotor end side. As a result, particularly those regions are cooled optimally in which the dissipation of lost heat is problematic.

  • Patent number: 8022580
    Abstract: A plastics injection-molding machine is to be equipped with a more compact drive that undergoes less wear. For this purpose, it is envisaged to integrate the direct rotational drive into the direct linear drive. Accordingly, the electric linear motor has a pot-shaped external rotor (13), in the inner space of which the main part of a hollow-cylindrical stator (16) of the linear motor is arranged and which is firmly connected to the output shaft (10). The rotary drive has a stator (18), which is mounted on the inner wall of the hollow-cylindrical stator (16) of the linear motor, and a rotor, which is firmly coupled to the output shaft (10) within the stator (18) of the rotary electric motor. This direct drive produces a very compact type of construction and it is possible to dispense with easily wearing threaded spindles.

  • Patent number: 8022587
    Abstract: Electric machines which are excited with permanent magnets are to be improved in terms of their smoothness of operation and their loss properties. For this purpose, an electric machine is proposed comprising a first active part (40) on which one electric magnet (41, 42) and at least one permanent magnet (44) are mounted, and a second active part (43) which has a multiplicity of pole teeth (45, 46) and which interacts magnetically with the first active part (40). The pole teeth (45, 46) are spaced apart from one another in a non-uniform fashion in the direction (3) of the movement of the electric machine and/or have different average widths from one another, with the respective width of a tooth being measured in the direction (3) of movement and being averaged in terms of the extent of the tooth in the transverse direction with respect to the direction of travel. The geometry of the tooth causes the harmonics of the magnetic field to be influenced in a selective fashion.

  • Patent number: 8016049
    Abstract: In a method of installing a borehole heat exchanger in the earth, a channel is formed in the earth by means of a pushing device, thereby causing a compression of the earth as a result of earth being displaced, and inserting a borehole heat exchanger in the channel, causing an elastic component of the earth to move toward the heat exchanger as the earth relaxes in order to provide an intimate contact between the earth and the heat exchanger. Installation of the borehole heat exchanger in elastically displaced earth ensures not only a stable and lasting securement of the heat exchanger in the earth but also the intimate contact between earth and heat exchanger wall so important for heat exchanger.
