Abstract: A method for determining optimum enamel die sizes for each of a plurality of dies for fabricating magnet wire includes a series of calculations based upon an empirically determined build factor for each of the enamel coatings used in the fabrication process. The build factor is a measure of the effective diameter increase of a wire passed through a coating die when the diameter of the wire entering the die is known and a selected thickness of wet enamel coating exiting the die is known. The build factor a given enamel coating is primarily dependent upon only the solids content of the enamel coating solution, and is largely independent of the chemistry of the coating solution. A simple relationship between build factor, die size, and wire size allows consistent fabrication of magnet wire in accordance with pre-selected specifications and with virtually no scrapped wire due to oversized final wire diameters.
Abstract: Process to monitor and control the quality of rolled products from hot-rolled processes which produce products such as sheets, rods, etc., from input stock such as slabs, billets, etc. The process estimates in advance the expected material properties of the end product at each step of the hot-rolling production process. The process further provides that conditions, such as temperature, reduction depth, etc., are detected on-line throughout the entire rolling process and from the values obtained, via interrelated physical—metallurgical and/or statistical models describing the whole rolling process, the mechanical/technical material properties to be expected, particularly the yield point, the tensile strength and the breaking elongation point of the rolled product, are calculated. On-line detection of the actual and momentary production conditions is necessary to allow the material properties to always be estimated in advance.

Abstract: The width of bands to be laminated on a mill train is adjusted by vertical upsetting rollers, resulting, however, in a narrowing at the band ends due to the asymetric material flow there. In order to solve the problem, the upsetting rollers are so designed as to move at the passage of the band ends in keeping with a curve defined according to specified parameters. The parameters are based on neuro-computer made predictions related to the milling process.

Abstract: The wiring harness has a plurality of first sub-harnesses and a plurality of second sub-harnesses. The first sub-harness has a first press-fit terminal joined to each end of a first electrical cable, and the first sub-harness has a first isolator holding the first press-fit terminal. The second sub-harness has a second press-fit terminal, a crimp terminal, a connector housing for accommodating the crimp terminal, and a second isolator supporting the second press-fit terminal. The second press-fit terminal is connected to one end of a second electrical cable, and the crimp terminal is connected to the other end of the second electrical cable. The press-fit terminals held by different ones of the isolators can be connected to one another when any of the first and second isolators are layered.
Abstract: A device for the simulation of spinning machines with a view to their optimum economic use and operation. Starting from material properties of a preproduct (1) determined by measurement, as well as from configuration and setting parameters (3) of such a spinning machine, material properties (2) of the intermediate or output products which are being produced, which properties can be determined by measurement, are predicted using a process model describing the behavior of the spinning machine, by a simulation device. The process model on which a method being based is presented by a neural network. The coefficients determining the actual behavior of this neural network area calculated from a set of sample data in a training phase. This sample data and/or from otherwise conclusively predicted properties of the behavior of such a spinning machine.
Abstract: Under the conditions that the tool is movable in an X-axial direction for approaching a work W and in a Y-axial direction perpendicular to the X-axial direction, the tool is moved at a specified speed in the X-axial direction to make the tool approach a work W and at the same time the tool is reciprocally moved at a specified frequency and a specified amplitude to detect a load fluctuation component for the tool in the X-axial direction during movement of the tool, and contact between the tool and the work W is detected according to this load fluctuation component.
Abstract: For making a nest of cuts (N) for cutting blanks out of flat, irregular workpieces (W), the contour (U) and the flaws (F) of the spread workpieces (W) together with a workpiece characteristic are detected by means of a digitizing unit (3), and the corresponding data are read into a computer (5), which on the basis of these data and the data stored in the computer (5) concerning number, shape and quality requirements of the blanks calculates and stores a nest of cuts and utilizes the detected workpiece characteristics of the workpieces (W) as a workpiece code for allocating the nests of cuts (N) to the respective workpieces (W).

Abstract: A sensor detects the absolute angular position of a rotatable clamp arm between full opened and full closed positions. The sensor is coupled to a clamp arm pivot shaft to provide output signals corresponding to the absolute position of the clamp arm. One or more programmable angular position set points are setable at angular positions in advance of the full open and full closed positions of the clamp arm. Outputs are generated when the clamp arm reaches and/or exceeds each set point.
Abstract: Low voltage logic circuitry is used to permit an entire subsystem of an industrial controller to be placed within a hazardous environment to receive a high speed serial link and undertake the control of multiple control points without expensive and awkward long cable runs and electrically isolating circuits for each cable run. Energy and bandwidth limiting on the high speed link allows power levels commensurate with high data rates yet intrinsic safety of the media allowing it to freely pass in and out of the hazardous area. A mixture of intrinsically safe and non-intrinsically safe equipment on the same logical rack is allowed through a bus isolator providing isolated data communication in backplane fashion between modules while wholly isolating power transmission along the backplane.

Abstract: A rolling mill system associates an autonomous control unit with each piece of equipment in the rolling mill system. The autonomous control unit has a model of the particular piece of equipment, for example, of the rolling mill, a reheat furnace or a cooling bath, and data indicating constraints on the operation of the equipment. A metal shape to be produced is described as a set of machine independent steps, and the performance of these steps is bid upon by the autonomous control units according to the constraint models and internal goals. Bids having conflicting requirements may generate counterbids until a complete plan for the production of the product is generated.
