Abstract: Gear pump with intermeshing gearwheels enclosed by a housing with bearing journals on shaft axes projecting laterally from the gear wheels mounted in the housing by slide bearings each having a slide bearing length, each having a lubrication pocket with radial expansion. The lubrication pocket is spaced from a gear-side end face of the respective slide bearing by a first distance, having a first bar with a first bar width with axial expansion corresponding to a slide bearing surface. The lubrication pocket is spaced apart by a second distance from the bearing end face opposite the gear end face. A second bar with a second bar width with axial extension corresponds to a slide bearing surface, a bore leads through the slide bearing and communicates with the lubrication pocket at an injection point. The bore is operatively connected to a conveying device for conveying lubricating medium into the lubrication pocket.

Abstract: Gear pump with intermeshing gear wheels enclosed by a housing with bearing journals arranged on shaft axes, each projecting laterally from the gear wheels, which are mounted in the housing by means of slide bearings, having a slide bearing length, the slide bearings being lubricated with pumped medium. The invention is characterized in that a filling pocket with radial expansion is incorporated in each of the slide bearings in the region of a pump pressure side, the filling pocket being spaced from a gear-side end face of the respective slide bearing by a distance, so that a bar with a bar width with axial expansion corresponding to a slide bearing surface is formed, and in that a lubrication groove with a tampering cross-section is provided in each of the slide bearings, the lubricating groove starting from an end on the gearwheel side towards a slide bearing end and starting at the filling pocket on the gearwheel side and communicating therewith.

Abstract: Gear pump with meshing gears enclosed by a pump housing, with bearing journals arranged on longitudinal axes and each projecting laterally away from the gears, wherein at least one of the bearing journals has, at least over part of its axial extension, a bearing journal diameter that lies in the range of 90% to 100% of a root diameter of the toothing of the associated gear. A toothing width (b) is at least twice the dimension of a distance (a) between the longitudinal axes, the toothing width (b) being an extension of the gears parallel to the longitudinal axes.

Abstract: The invention relates to a sealing arrangement (1) for conveying devices, in particular for gear pumps, in which an inner space (5) can be sealed off from an outer space (6), wherein the sealing arrangement comprises at least two parts (2, 3) each having at least one sealing surface (20, 21), wherein the sealing surfaces (20, 21) comprise: a first seal (11) along a first, medial perimeter of the sealing surface (20, 21), a second seal (12) along a second, lateral perimeter of the sealing surface (20, 21), a recess (15) between the first seal (11) and the second seal (12), characterized in that the recess (15) can be connected to a source (30) of a flushing medium such that the recess (15) can be actively flushed with the flushing medium.

Abstract: An NMR measuring system comprising an NMR probe head (34) with a cooled NMR receiver resonator (35) is connected via a transfer line (19) to a cooling device for supplying two coolant loops with coolant at two different cryogenic temperature levels, wherein the transfer line (19) contains one coolant feed line and/or one coolant return line for each of the two coolant loops for cooling the NMR probe head (34), and where these feed lines and return lines terminate on one side in four preferably standardized connection points (7,11,12,16) of the cooling device and on the other side, facing the probe head, in a standardized cryo-coupling device (28) which in its turn can be connected to a matching also standardized cryo-coupling device (29) attached to the probe head.

Abstract: A nuclear magnetic resonance (NMR) spectrometer probe head having one or more drive units, one or more transmission units and one or more drive shafts which are coupled to adjustment rods and a means for directly mounting and fastening the drive unit, transmission unit, and drive shaft to the lower portion of the probe head during operation of the NMR spectrometer, which increases user comfort and freedom of motion below the magnet. The probe head also having an actuator for remote control adjustment of electrical and/or mechanical units, e.g. trimmer capacitors, variable resistors, and adjustable inductors within the probe head. The probe head is characterized in that the amount of space needed for the actuator is minimized, access to the region below the magnet is optimized, and installation of the actuator is simplified because the actuator is an integral part of the NMR-probe head within an NMR-spectrometer.
