  • Patent number: 11493118
    Abstract: A ball screw drive includes two screw drive parts (3, 4), namely a lead screw (3) and a nut (4). The ball screw drive also includes a deflection element (6) for the individual deflection of balls (5) is inserted into a recess (7), formed by one of the screw drive parts (3, 4), such that a gap (16) is formed between the base (15) of the recess (7) and the deflection element (6), and such that lateral contact surfaces (17) of the deflection element (6) which are located next to the recess (7) rest on the screw drive part (3, 4).

  • Publication number: 20160306933
    Abstract: A method for creating medical documentation in a hospital information system uses a mobile device, in which a target form is created in the hospital information system as a result of an adapted process for communicating an optimized form definition to a mobile device, which is then used to collect and record the necessary data for the target form using an intermediary data structure called a dummy form. The dummy form is a limited version of the target form (containing a subset of the data of the target form), but behaves in the hospital information system as a target form. A part of the data is captured as digitally recorded multimedia content, which may transcribed later on as text in the target form.

  • Patent number: 6357336
    Abstract: An oscillating bearing arrangement, for axial piston pumps (1) of a wobble plate type, comprises a shaft (6) connected for rotation about its longitudinal axis (13) to a wobble plate, the shaft (6) being coupled with a shaft bearing (3) arranged in a housing (4) and comprises an inner ring (15) and an outer ring (16), and oscillating driven elements (14) being spring-suspended against the wobble plate characterized in that the wobble plate (23) which is substantially trapezoidal-shaped in longitudinal section is arranged concentrically in a reception bore of the inner ring (15) of the shaft (3).

  • Patent number: 6132099
    Abstract: The invention relates to a radial bearing assembly for a drive shaft of vehicles which connects a transmission (2) with a driven front wheel (5), with a laterally sealed radial bearing (11a) received in a holder (15) which is securely fixed in place on the side of an internal combustion engine for supporting the drive halfshaft (7). In accordance with the invention, a drive shaft (7) in the form of a hollow shaft is provided, with an inner ring (12a) of the radial bearing (11a) being formed from a sheet metal band in a non-cutting fashion. The radial bearing (11a) is received via a spherically shaped outer surface area (14) of an outer ring (13a) in an oriented position in the holder (15) which is assembled from flanges (16, 17).
