Abstract: An assembly for automatically detecting contactlessly elongate objects (W). The assembly comprises an inductive measuring system (E) and a first optical measuring system (D) for the object (W) within a housing (2). The inductive measuring system (E) is an eddy current sensor for determining an electromagnetic characteristic of the object (W) and has half coils (E1a, E1b) which wind around the object (W) and forms an inductive cylindrical measurement volume (Ev). The half coils (E1a, E1b), together with a capacitor (E2), form a parallel oscillating circuit (E6), which is connected to an electronic evaluating circuit (E5). The first optical measuring system (D) determines the outside diameter (Wdo) of the object (W) and an optical disk-shaped measurement volume (DCPv) is formed between the two half coils (E1a, E1b). Optionally, the assembly, by a second optical measuring system (C), determines the color and the position by a third virtual measuring system (P).

The functional and local separation of the two measuring systems (C, D) is achieved by using different wavelength ranges and by a long-pass filter (C3). A third, virtual measuring system (P) may be provided for the purpose of determining the cable location and is used to weight measured values of the color measurement and measured values of an optional eddy current sensor. The optical measuring systems (D, C, P) for determining the diameter, the color and the position have a common optical disc-shaped measuring volume (DCPv) which is preferably arranged centrally in the guide device (4a, 4b) for the elongate object (W).

Abstract: The invention relates to a device for detecting contact of a tool (2a, 2b) with an electrical conductor (5b) encased by an electrical insulation (5a). In order to ensure a reliable, robust and simple display of the tool-conductor contact for potential-free and short cable lengths, the tool (2a, 2b) consisting of an electrically conductive material is fastened to a tool holder (1a; 1b) made of electrically conductive material. A thin electrical insulation is provided between tool (2a, 2b) and tool holder (1a, 1b) so that these components together with the coaxial cable form a capacitor (CS). An inductance (La; Lb) is connected parallel to this so that a high-Q LC resonant circuit is formed between tool and tool holder. The electronic circuit arrangement excites the resonant circuit and determines characteristic oscillation parameters of this resonant circuit.

Abstract: For cooling and/or heating a machine casing, a method and an arrangement is disclosed in which the machine casing is provided with cooling channels in which pipes are received. Between the pipes and the walls of the cooling channels, a cavity remains through which a cooling medium is circulated. A liquid heat exchange medium is circulated through the pipes. In order to vary the heat energy exchanged per time unit between the pipes and the machine casing, the kind of the medium circulating in the cavities is changed, or its composition is changed, or the flow velocity of the heat exchange medium is varied, or any desired combination of the above measures is realized. Thus, the heat flow, i.e. the exchange of heat energy per time unit, can easily be influenced by the provision of cavities between machine casing and heating or cooling medium by controlling its limiting heat exchange factors, i.e. thermal conductivity and heat transfer resistance.
