Abstract: A method is disclosed for producing a heat exchanger having at least one heat transfer surface, wherein the heat is used in a thermodynamic process that uses a fluid that is condensed, expanded, evaporated, and compressed in a cycle process. The area of the heat transfer surface may be dimensioned with respect to a minimum surface area measurement of the heat transfer surface, the minimum surface area measurement being required at least for transmitting a minimum heat quantity to the fluid used with the heat exchanger in order to prevent a condensation of the fluid before, during, and after the compression process. The area of the heat transfer surface may be dimensioned based on a correlation between the molar mass of the fluid and the minimum surface area measurement of the heat transfer surface.

Abstract: A fitting system is provided that includes a plurality of fitting lines for fitting printed circuit boards with electronic components. A method for allocating printed circuit boards to the fitting lines includes: (1) determining requirements for fitting each of a plurality of printed circuit boards with allocated components; and (2) allocating the printed circuit boards to fitting lines under predetermined conditions by integral linear programming. Equipment families are determined for the fitting lines on the basis of the allocation, and the allocation is repeated until a criterion has reached a predetermined threshold. The criterion is established on the basis of the number of equipment families of the fitting lines, where an equipment family includes a quantity of different components with which a fitting line may be fitted in order to fit a predetermined amount of printed circuit boards.

Abstract: A method for controlling an electrical energy distribution network in which electrical power is provided via network nodes connected via power lines is provided. A portion of the network nodes are controllable network nodes with respective local controllers, and at least a portion of the controllable network nodes are energy generators. The energy distribution network is coupled to an energy transmission network at a point of common coupling and provides electrical power to the energy transmission network at the point of common coupling. The electrical power originates from the controllable network nodes. A central controller communicates with the local controllers and the energy transmission network. The central controller controls the energy distribution network with the aid of the communication with the local controllers and the energy transmission network such that at the point of common coupling, primary control power and short-circuit power are kept available for the energy transmission network.

Abstract: A method for producing or disassembling an electronic assembly are provided. The assembly may have a heating device integrated into a substrate. The heating device can be heated via an external power supply during the assembly process so that, for example, solder connections of an electric component can be melted. The heating device can also be used when operating the electronic assembly, and the heating device can then be directly actuated by the component. For this purpose, an electric connection is then established between the component and the heating device, the connection not yet being provided during the thermal assembly process in order to protect the electronic components of the circuit from being damaged.

Abstract: A transformer including a coaxial transmission line and a series circuit of discrete stages of voltage sources arranged along a main axis of wave propagation. Electromagnetic waves are propagated along the coaxial transmission line in each stage and are coupled in the coaxial transmission line by pulse currents. Each stage has a coupling-in inductance formed by discrete inductances that generate the pulse currents. The discrete inductances are magnetically coupled to each other such that magnetic fluxes of the discrete inductances are superimposed on one another and added to one another along a circular line that is rotationally symmetrical to the main axis of wave propagation.
Abstract: The invention relates to a production module (PM) for processing or handling a product (P) in a production system (PS), which production module (PM) has a product detection module (PE) for reading in product parameters (PP) associated to the product (P), and an interaction module (IA) for assigning an adjacent production module (PM1, PM2) to a transfer port (PTI, PT2). Furthermore a local assignment table (ZT) is provided, in which non-adjacent conveying objectives (PM3) in the production system are in each case assigned to one of the transfer ports (PTI, PT2). A balancing module (AM) serves for iterative reading of first assignment information (ZII) of a corresponding assignment table (ZTI) of a first adjacent production module (PM1), for iterative formation of the local assignment table (ZT) with the aid of the read-in first assignment information (ZII), and for iterative transfer of second assignment information (ZI2) of the local assignment table (ZT) to a second adjacent production module (PM2).
