摘要:
A balancing system for an agricultural vehicle includes a balance weight which has take-up pins at its sides. The pins are oriented coaxially to a common pivot axis so that the balancing weight can be taken up by the lower links of a three point implement hitch. When the balance weight has been taken up, it can be moved from a position of the center of gravity (S) of the balance weight close to the vehicle to a position distant from the vehicle. In order to attain a balance as optimal as possible, the position of the center of gravity of the balance weight in its position close to the vehicle is located below the pivot axis. Pivoting devices are provided so that the balance weight can be pivoted about the pivot axis so that it can also be brought from a position close to the vehicle to a position distant from the vehicle, where the balance weight occupies a lower position of the center of gravity in the position close to the vehicle than in the position distant from the vehicle.
摘要:
The invention relates to a machine for the production of a knitted fabric using stretched fiber material (4). The machine comprises a stretching device, a spinning device having a spinning element, a transport pipe (17) connected thereto, and a thread guide (27) equipped with a passage (30) for the fiber material (4). According to the invention, an exit end (17d) of the transport pipe (17) has a cross-section (D2), which is as large as, or smaller than, an inside cross-section (D1) on an exit end of the passage (30). The intensity of the air blast current is selected such that it enables sure insertion of the fiber material (4) in the needles of the machine forming the loops.

The present invention relates to an electrode catheter for defibrillation, mapping or ablation of cardiac tissue. Said catheter comprises a terminal (40) on the proximal end of the electrode catheter and one or more sensing and/or treatment electrodes (14, 16) that are situated on or in the vicinity of the distal end of the electrode catheter, in addition to at least one electric conductor (44, 62), which is used to electrically connect a respective sensing or treatment electrode to the terminal. The electric conductor (44, 62) is composed of carbon and the electrode catheter is configured to be suitable for us as part of magnetic resonance tomography and for connection to electrophysiotherapy equipment. Said catheter comprises at least one defibrillation electrode, or at least one sensing electrode (14, 16) for the recording and evaluation of cardiac tissue potentials, or at least one treatment electrode (14) for delivering high-frequency currents for ablation purposes.

In a profiled rail guide comprising a traveling carriage that is supported through a carrier body (3) on a guide rail (1) for sliding along the guide rail (1) on raceways (2) that are arranged on two long sides of the guide rail (1), the carrier body (3) comprises at least one of longitudinal holes (5, 6) extending parallel to the guide rail (1) and transverse holes (7) extending at right angles to the guide rail (1).
摘要:
A fuel tank for motor vehicles is constructed so that the generation of noise in the fuel tank due to sloshing fuel is minimized. For this purpose, a dampener element, which is permeable to the flow of liquid fuel, is attached to the interior of the tank. According to the invention, the dampening element has a dimensionally stable lattice or similar network structure. This dampener element is attached near the bottom wall of the fuel tank and has a generally horizontal orientation.

The start-up of a computer system takes place rapidly using a computer system having a recovery system which collects data for the recovery in parallel fashion in a common memory so that the data can be transferred to peripheral units of the computer system. The collection begins with collecting the data into a local memory of a processor and then transferring the data to the common memory before transferring the data to the peripheral units.
