Abstract: In a superconducting magnet arrangement, such as used in a magnetic resonance system, and a power management method therefor, an enhanced economic power mode (EPM) is implemented wherein the compressor operation is controlled by magnet pressure, temperature and time, so as to ensure the readiness of the magnet system for a scanning operation upon exiting the enhanced EPM. A processor implementing the enhanced EPM looks for a signal that indicates that the magnet system is operational and, in the absence of that signal for a predetermined period of time, enters into EPM. Exit from EPM occurs if certain conditions are violated, but then re-entry into EPM is attempted (re-starting EPM), thereby making the magnet system ready for operation again, if and when a patient scan is to be implemented.

Abstract: In a system and operating method wherein the system includes a medical apparatus and an operator console, a first input processor is assigned to the operator console and acquires a shutdown command that triggers a shutdown operation of the operator console, and a second input processor is assigned to the medical apparatus and acquires a startup command that triggers a startup operation of the medical device. A first interface forwards the shutdown command from the operator console to the medical apparatus wherein a shutdown operation of the medical apparatus is triggered, and a second interface forwards the startup command from the medical apparatus to the operator console, wherein a startup operation of the operator console is triggered.

Abstract: A magnetic resonance imaging system has a superconducting magnet housed within a cryostat, a cryogenic refrigerator that cools within the cryostat, a helium compressor that supplies compressed helium to the cryogenic refrigerator and to receive a return flow of compressed helium from the refrigerator, and a magnet supervisory system controlling operation of the magnet resonance imaging system. An apparatus is provided for controlling the speed and/or timing of operation of the helium compressor in accordance with predefined algorithms in response to system state data.

Abstract: A magnetic resonance imaging system has a superconducting magnet contained within a cryostat, the cryostat being cooled by a cooling system that includes a healing and compressor, a refrigeration device and a local supervisory system. The helium compressor provides compressed helium to the refrigeration device, and the local supervisory system controls operation of the refrigeration device. The helium compressor is in communication with the local supervisory system, and also is able to communicate, independently of the local supervisory system, with a remote service provider.

Abstract: The invention relates to a crankshaft drive for an internal-combustion engine of V-type having a crankshaft with two mutually offset crank pins per throw, the pins being inter-connected via a narrow intermediate element. In order to ensure an optimum axial guidance of two connecting rods mounted rotatably on the crank pins, even without an intermediate web, the intermediate element has a cross-sectional area which largely corresponds to the overlapping sectional areas of the two crank pins. Moreover, each connecting rod is guided by means of an axial stop surface arranged on the large connecting rod eye of the adjacent connecting rod.

Abstract: The invention relates to a crankshaft drive for an internal-combustion engine of V-type with a crankshaft, which has two mutually offset crank pins per throw, which pins are interconnected via an intermediate web. In order both to minimize the amount of machining required on the intermediate web and to ensure an optimum axial guidance of two connecting rods mounted on the crank pins, the intermediate web has an axial stop collar on either side and the intermediate web is of an enlarged design such that the axial stop surface of the connecting rods cannot jut out from the projected area of the intermediate web in any crankshaft position.
