摘要： An industrial truck, particularly a high-lift truck, comprising a lifting frame provided with extensible mast sections and a load-carrying carriage, is provided on the fixed mast section and, if desired, on extensible mast sections, with laterally disposed vertical rails, which serve in alternation as carriers for rotatably mounted guide roller for engaging guideways on adjacent rails or to provide guideways for such guide rollers. The guideways are provided at least on one side with a bordering ledge for the lateral guidance of the guide rollers. At least part of the guide rollers (20, 22, 30; 24, 26, 27, 28; 102-104; 105, 106; 108, 109; 143), particularly those disposed on one side of the lifting frame (2), are axially displaceable. In one embodiment the guide rollers (20, 22; 24) disposed on one side of the lifting frame are axially displaceable in their bearings and those (19, 21; 23, 25) disposed on the other side of the lifting frame are axially fixed in their bearings. In another embodiment an axial displacement is permitted in that the guideways (127-129) for the associated guide rollers (20, 22, 30; 20', 22', 30'; 24-27, 65, 143) disposed on one side of the lifting frame (2) are wider than the treads of the associated guide rollers and said guide rollers are axially fixed in their bearings.

摘要： The invention relates to electrophysiology catheter systems and their use, such as in an MRI environment, and in particular to analysis of electric signals from such. An electrophysiology (EP) catheter with a plurality of electrically isolated electrode segments arranged in longitudinally spaced bands around the catheter is used to detect electric signals. A workstation receives the electrical signals which are then processed by a processing unit. Electric signals from electrode segments can be used to determine roll angle information of the catheter in relation to patient anatomy by determining signals from electrode segments in contact with tissue. Also, electric signals can be used to extract a reference signal that can be used to correct for gradient induced artifacts.

摘要： The present invention relates to a catheter (6) comprising: a connector (65, 66) at a proximal side of the catheter for connecting the catheter to an external signal transmission/receiving unit (10) for transmitting and/or receiving signals, an electrode (63, 64) at a distal side of the catheter, and an electrical connection including an electrical wire (61, 62) for electrically connecting the electrode and the connector for the transmission of signals between the electrode and the connector, wherein the electrical connection has a high electrical resistance of at least 1 kΩ, in particular of at least 5 kΩ. Thus, the present invention provides a solution to prevent excessive heating during EP interventions under MR guidance by using highly resistive wires and or lumped resistors as connections within catheters.

摘要： A magnet system, in particular for a magnetic resonance examination system, comprises a superconductive main magnet having a near group of coil windings and a remote group of coil windings. A gradient coil system forms a source of power dissipation into at least part of the coil windings. The near group of coil windings and the remote group of coil windings are near and remote from the source of power dissipation, respectively A cooling system has a high-temperature cooling station and a low-temperature cooling station. The high-temperature cooling station cools mainly the near group of coil windings. The low temperature cooling station cools mainly the remote group of coil windings. The near and remote group optionally are made of different superconductive materials. Thus, additional degrees of freedom are achieved which allow less expensive magnet design.

摘要： For x-ray tubes the focal spot temperature is a critical factor. According to an exemplary embodiment of the present invention, an examination apparatus is provided which has a synchronisation unit providing an operation mode for a stereo tube in which the anode rotation frequency is synchronised with the switching frequency such that the switching frequency is a half integer multiple of the anode rotation frequency. This may lead to a significant reduction of the focal spot temperature.
