Abstract: A roller table for supporting and transporting a hot glass strand. A plurality of rollers arranged parallel to each other and perpendicular to the transport direction of the glass strand are capable of being selectively rotated in the direction of transport of the glass strand. At least some of the rollers are sleeves, the casings of which are which are gas-permeable on at least a portion of their surfaces and the casings are provided with a supply of pressurized gas which is emitted through the openings of the gas-permeable surfaces.

Abstract: A vessel electrode line (10) for pacemaker stimulation and/or for sensing cardiac actions in the region of the atrium has an oblong base body (11) that receives at least one electrode supply line, and at least one electrode (13, 14) that is mounted on the base body, with the effective diameter of the electrode(s) being nearly identical to the diameter of the base body, and with fixing elements (11a) that essentially do not act as an electrode, and particularly have at least a partial insulating surface, being provided for fixedly positioning the electrode(s) with respect to the vessel wall.

Abstract: An electrode arrangement is provided having an electrode line which has a closed casing for sealing off its interior relative to the surrounding area. At its distal end, electrically conducting surface regions serve as electrodes. A fixing mechanism anchors the distal end in a body tissue, in particular heart tissue and is adapted to be separable from the rest of the electrode line in such a way that the rest of the electrode line is also closed at its distal end when the fixing mechanism is separated off. The interior of the electrode line is sealed off relative to the surrounding area even when the fixing element is separated off. The electrode arrangement is characterized by a mechanism for separating off the fixing mechanism, which is adapted to effect separation by virtue of forces acting axially within the electrode line.

Abstract: The invention concerns a roller table for carrying and transporting a hot glass band.

Abstract: A catheter for the introduction into blood vessels having a lumen and guide means arranged therein wherein the guide means include a pre-bent wire (26) displaceable in the longitudinal direction of the catheter (10) and the catheter (10) has at its distal end an exit lock means (38) such that the pre-bent wire (26) can issue from the catheter (10) through the exit lock means (38) at the distal end.

Abstract: An implantable electrode arrangement which includes an electrode line (10, 10′) with a plurality of electrically conductive surface regions (14, 16) in the region of the distal end of the electrode line for outputting electrical signals to a heart and/or for receiving signals from a heart, which can be electrically connected by way of the electrode line (10, 10′) to a cardioelectric device such as a defibrillator or cardiac pacemaker, which device receives electrical signals and/or outputs pulses, wherein there are switching means (20, 22; 34) which are of such an arrangement and configuration that the connection between individual ones of the electrically conducting surface regions (14, 16) and the cardioelectric device can be permanently switched on or off in the region of the electrode line (10, 10′).

Abstract: An implantable electrode arrangement which includes an electrode line (10) with a plurality of electrically conductive surface regions in the region of the distal end of the electrode line (10) for outputting electrical signals to a heart and/or for receiving signals from a heart, which can be connected by way of at least one electric line (18) of the electrode line (10) to a cardioelectric device such as a defibrillator or cardiac pacemaker, which device receives electrical signals and/or outputs pulses, wherein arranged in the electrode line (10) are switching means which are connected to the electric line (18) and at least one electrically conducting surface region and which are such that they can make or break a connection between the electrically conducting surface region and the cardioelectric device in the region of the electrode line (10), and arranged in the electrode line (10) are control means which are connected to the electric line (18) for receiving control signals and to the switching means for

Abstract: A system for inerting a casting vessel, such as a traversable ladle or torpedo vessel, used for transporting molten metal, the vessel being positioned below the molten metal outlet opening at a transfer station, and the vessel cavity being flushed with an inert gas both prior to the molten metal inletting and during the inflow of the molten metal in such a manner as to avoid contact between the molten metal surface and the vessel and the atomospheric oxygen. A blowpipe is arranged in the vicinity of the molten metal outlet opening but does not intersect the molten metal stream, is located outside the free space profile of the vessel at least during the approach and return of the vessel, and terminates a distance from the vessel inlet opening and produces at its terminal end an inert gas stream which enters the cavity of the vessel adjacent the molten metal stream at an acute angle.

Abstract: It is proposed, in the case of at least one transport and discharge runner installed at a tapping orifice of the metallurgical furnace and a transfer station having a swivel or tilting runner in which the molten metal flows from the discharge runner by way of a distribution system into the outlet openings from which it flows into a preferably movable casting vessel, to cover the discharge runners conveying the molten metal from the tapping orifice of the metallurgical furnace with cover hoods, to screen off the transfer station in a substantially gastight manner, to sweep these interiors with inert gas and in addition to screen off the molten metal discharge stream from the outlet opening to the casting vessel by means of a pressurized inert gas covering which prevents air access and is substantally annular in cross-section. By these means, fume production is effectively avoided.
