Abstract: An NMR spectrometer (1) with a magnet system (2), which has a bore (3) through the magnet center (4) for inserting a measuring sample (5) in a transport container (7), and with a transport device for pneumatic transport of the sample through a transport channel (8) into and out of the magnet system. The transport device includes a mechanical interface (9) with a mounted exchange system (10) which has parking receptacles (11) temporarily storing the transport containers. In a transport position, the parking receptacle is inserted into the transport channel, to be loaded with a transport container, removed from the transport channel for temporarily storing the transport container, and reinserted into the transport channel for further transport of the transport container. In the transport position, the parking receptacle forms a part of the transport channel, which permits a faster automated change of the measuring samples in short measurement cycle times.

Abstract: Transport apparatus pneumatically conveying NMR test samples (2) from or to an NMR spectrometer (1) through a tubular transport channel (3) includes a device (4) generating positive pressure in the end of the transport channel that is remote from the spectrometer. The transport channel has a tube system which has a gas-tight outer tube (5) having an outer diameter Da and an inner diameter da and an inner tube (6), arranged coaxially with respect to the outer tube, having an outer diameter Di<da and an inner diameter di. The inner diameter di of the inner tube is greater than or equal to the outer diameter DP of the test samples, and the inner tube includes mutually spaced cross-holes (7) designed as through-holes. This provides accurate current position determinations for the sample in the transport channel, and reduced risk of damaging the sample during transport.

Abstract: A transport device for transporting an NMR sample to a probe head (16), having a shuttle (15) and a locking apparatus (3) for the rotor (5), which, when attaching the shuttle to the probe head, releases the rotor, and having a detecting apparatus for detecting the rotor in the shuttle. The probe head has a positioning apparatus (2), which holds the probe head in a defined measuring position relative to the shuttle. The detecting apparatus includes a sensor line, which transmits a signal dependent on the position of the probe head to the shuttle's end. A first portion (1a) of the sensor line is mounted inside the shuttle and extends from the rotor in a transport state to the end of the shuttle. A second portion (1b) of the sensor line is mounted inside the probe head and, in the measuring position, is directly adjacent to the first portion.

Abstract: A device (20) for bonding or welding a membrane, including an undercarriage (30) for supporting the device on the membrane at least at one contact point, which is formed by a pressing element (40) for pressing the membrane onto a metal plate to be bonded or welded thereto, and at least at two further contact points, which are formed by castors (31, 32). A frame (42) extends upwards from the undercarriage (30), wherein the device (20) can be manoeuvred using the frame. The pressing element (40) includes a heating device (46), which is designed as an induction coil, by which the metal plate, which is provided with an adhesive or weldable coating, can be heated. An induction generator and a control and cooling device thereof are mounted in or on a housing (50), which is fixed to the frame (42) at a distance (A) above the undercarriage (30). The device (20), which is formed as one part, can be tilted for moving around a castor axis (28) and can then be lowered via the metal plate onto the membrane.

Abstract: A screwdriver adapter (1) is provided with a receiving part (3) having an interior space (5). At the open end of the pot-shaped receiving part (3) there is inserted a nut-shaped element (2) in torsionally rigid and axially secured relationship. Adjoining the tool driving means (6) there is disposed a channel (8), which passes axially through the nut-shaped element (2) and extends as far as the interior space (5) of the receiving part (3). Drive portions broken off by overtorquing a screw in the tool driving means (6) can travel via the channel (8) into the interior space (5) of the receiving part (3), where they can be collected until an emptying process.
