Abstract: A control device for a process, in which a controlled variable can be influenced with the aid of a plurality of different regulating units, which in particular are based on different physical principles. A set point and the controlled variable are fed to both a first controller and a second controller. The first controller is located as primary controller in automatic operation and has a regulating range of the first manipulated variable that is defined by limiting values. The second controller can be switched between automatic operation and tracking operation, in which the controller generates a predefined or predefinable constant value of the second manipulated variable. By means of a logic circuit, the second controller is switched to automatic operation if a limiting value of the first manipulated variable is reached, and otherwise to tracking operation.

Abstract: A switch includes connection elements, connectable via a switching contact whose movable contact area is formed on a movable contact element which bears against the stationary contact area in the closed position. In order to achieve a design with improved positional accuracy, an embodiment of the invention proposes that the two connection elements and the movable contact element each have a planar flat side and all flat sides lie in a common plane. In an embodiment, the connection elements are arranged on one side of the common plane and the movable contact element is arranged on the other side; a subarea of the flat side of one connection element forms the stationary contact area; a subarea of the flat side of the other connection element forms a planar bearing area; and the movable contact element with its flat side bears movably against the bearing area.

Abstract: In a method and a control sequence determination device for determining a magnetic resonance system control sequence includes at least one radio-frequency pulse train to be emitted by a magnetic resonance system, a target magnetization is acquired and a k-space trajectory is determined. A radio-frequency pulse train for the k-space trajectory is then determined in an RF pulse optimization method using a target function, wherein the target function includes a combination of different trajectory curve functions, of which at least one trajectory curve function is based on a trajectory error model. A method for operating a magnetic resonance system uses such a control sequence and a magnetic resonance system has such a control sequence determination device.

Abstract: A device under test, such as a point machine, which is screwed to two longitudinal supports, which can be individually moved horizontally and vertically is provided. Thus, a highly flexible solution is created, because even devices under test having unknown or asymmetric dimensions can be fittingly accommodated and positioned. Linear drives enable highly accurate positioning of the supports, in particular even if the supports are have high inherent weight or are already loaded with the device under test. According to one embodiment, the mechanical system is designed to grasp and/or to lift a mounting cart by means of the supports, on which mounting cart the device under test is fastened by screwing. This provides the advantage that the device under test can be tested while mounted directly to the mounting cart without separate transferring and screwing of the device under test being required.

Abstract: A spark gap including a capacitive energy store is provided. The spark gap is fed via a multiplicity of capacitors arranged in a form of a ring, wherein the capacitors are electrically connected to the anode and the cathode via ring-shaped and conical or funnel-shaped conductors. As a result, sudden changes in impedance can be avoided. At the same time, it is possible to realize as large a cross-sectional area of the conductor as possible within a very small space. Therefore, the spark gap has a switching response with a high rate of rise of the voltage pulse as soon as the spark gaps flash over. This results in an easily predictable switching response of the spark gap. The spark gap can be used, for example, to generate pulses of monochromatic X-ray radiation.

Abstract: An appliance has an operating unit with an actuating element for triggering a pre-determined action. The actuating element is mechanically actuatable by force of a user. The actuating element is preferably a mechanically actuatable switch and/or key element. A touch-sensitive sensor is built into the actuating element, for detecting skin contact occurring as a result of the exertion of force for the mechanical actuation of the actuating element. The appliance is also embodied in such a way that, as a requirement for triggering the pre-determined actions, it is checked whether the actuating element is actuated and skin contact is detected by the touch-sensitive sensor. The appliance prevents defective actuations by associating touch-sensitive sensor technology with the mechanically actuatable actuating element. This ensures that mechanical actuation without skin contact does trigger the pre-determined action.

Abstract: A cooling system for a turbine airfoil of a gas turbine engine is disclosed, whereby the cooling system includes spanwise extending midflow blockers positioned within one or more cooling channels to maintain an internal through flow channel Mach number. One or more cooling channels may have a larger cross-sectional area proximate to an outer end of the airfoil than at an inner end. One or more cooling channels include midflow blockers extending into the cooling channel. In at least one embodiment, the midflow blocker may extend radially inward from the outer end of the airfoil. The midflow blocker may limit movement of cooling fluid from the pressure side to the suction side or vice versa. The midflow blocker may increase in size moving radially outward as the cross-sectional area of the cooling channel increases as well. Such configuration keeps the internal through flow channel Mach number within design limits.
