Abstract:
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.

Abstract:
An apparatus for manufacturing a medication comprising an ejector unit adapted for ejecting a predefined amount of a drug having a liquid component to a solid carrier substrate. The ejector unit comprises a capillary and a tubular piezoelectric actuator surrounding at least a part of the capillary. The apparatus further comprises a control unit adapted for applying an electric signal to the piezoelectric actuator which, in response to the electric signal, is adapted to generate a compressional wave in the capillary for ejecting the predefined amount of the drug via an orifice of the capillary. Moreover, a method of manufacturing a medication is provided, the method comprising ejecting a predefined amount of a drug having a liquid component to a solid carrier substrate. Furthermore, a medication is provided comprising a solid carrier substrate, and a predefined amount of a drug ejected with a liquid component to the solid carrier substrate by an ejector unit.
Abstract:
A hydraulic system includes an engine driven variable displacement hydraulic pump which supplies fluid to a hydraulic consumer and an electronic control unit. A flow rate adjusting unit includes a stop that can be brought into engagement with an adjusting piston. In order conform the power output of the pump to the operating conditions of the vehicle, the stop of the flow rate adjusting unit includes adjusting devices that can be controlled by the control unit, so that the maximum flow rate of the pump can be varied by the electronic control unit. The electronic control unit generates a control signal for the adjusting device as a function of a sensed engine speed.
Abstract:
A method and a knitting machine for producing a knitted product composed of fibre material fed by a roller pair (11c) are described. The stitches are formed as usual by knitting elements (3) being raised out of a non-knitting position into a fibre take-up position, while at the same time previously formed stitches are being knocked over, and being withdrawn again after the fibre material (6) is inserted. The presence of fibre material is monitored by means of a sensor (22), which when there is no fibre material present emits an error signal, as a result of which the knitting elements are prevented from being raised further into the fibre take-up position. According to the invention, when the error signal occurs, the knitting elements (3) are withdrawn from an intermediate position again without the previously formed stitches being knocked over and without the fibre material being taken up. In addition, the sensor is preferably arranged at a location between the roller pair (11c) and the knitting system (4) (FIG. 1).
Abstract:
The invention relates to a hydrostatic profile of a rail guide with a guide carriage. Viewed in cross-section through the rail guide, there is an imaginary first straight line parallel to the mid-surface, an imaginary second straight line parallel to an upper bearing surfaces and a third imaginary straight line parallel to a lower bearing surface. An angle alpha is formed between the first and the second straight lines, and an angle gamma is formed between the first and the third straight lines, the angle alpha having values of 10° to 45° inclusive and the angle gamma having values of 20° to 55° inclusive.
Abstract:
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.
Abstract:
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.
