摘要:
In a device for connecting two parts for the sake of high-precision fixation of the two parts in a defined positioning to one another, two connection pairs are provided, each comprising one wedgelike tab, assigned to the first part and extending in the connection direction, and one wedge-shaped notch, assigned to the other part and extending in the connection direction, with a course of the wedge that is contrary to that to the tab, and into which notch the tab can be pressed, causing deformation. The two connection pairs are oriented such that the press-in directions of the tabs into the assigned notches are opposite one another in terms of the connection direction.

A pendulum sliding bearing has a sliding bearing bushing provided for receiving a rotatable elements, such as shafts, axles and the like, the sliding bearing bushing having calotte portions at end sides, a bearing body formed of a metal plate and having a ring-shaped abutment surface for one of the calotte portions of the sliding bearing bushing, a wall extending substantially outwardly of the abutment surface, and a casing adjoining the wall and provided for insertion in a cylindrical opening, a spring disk having a central opening and an adjoining at least one second abutment surface for the second calotte portion of the sliding bearing bushing and having a radially outer edge fixed on the bearing body, the casing being subdivided into casing fields which extend substantially parallel to a longitudinal axial of the bearing body so that gaps are available between the casing fields, a plurality of supporting fingers extending at least over a width of the gaps from the wall in a direction opposite to a course of the casing.

A bearing for a driving shaft of an electrical machine is lubricated by a lubricant. Located between the bearing and rotating parts arranged on the driving shaft is a seal element for lubricant emerging from the bearing. The seal element is configured in the form of a slinger disk by which lubricant emerging from the bearing is returned to the bearing, thus resulting in a closed lubricant circulation. The slinger disk is produced entirely from an elastic material. Lubricant sent off from the slinger disk is returned directly to the bearing.
摘要:
A commutator machine, in particular a small direct-current motor, has at least one pair of permanent magnets (11) retained on a magnetic short-circuit element (10), the permanent magnets being of a single-substance ferrite material or a multi-substance material having portions of high coercivity and high remanence along the periphery of an armature (15) rotating inside the stator (12). By selecting suitable ferrite materials, depending on the required excitation field intensity or the required demagnetization stability, and by the proposed dimensioning of armature diameter (d.sub.A), magnet thickness (D.sub.M) and thickness of the short-circuit element (D.sub.R), an optimal configuration of the motor is obtained by attaining the maximum possible capacity with the lowest possible weight.
摘要:
A bacterial host is described which is transformed by a plasmid coding for a polypeptide precursor wherein the host comprises a multi-enzyme complex capable of reacting with the expressed polypeptide precursor to produce a polypeptide comprising at least one dehydroamino acid and/or at least one lanthione bridge. A process for producing a polypeptide comprising at least one dehydroamino acid and/or at least one lanthione bridge, such as gallidermin, is also described. A plasmid capable of transforming a bacterial host is additionally described. Also disclosed are recombinant DNA molecules which specify Epi B, Epi C, Epi D, Epi P and Epi Q, enzymes which are involved in the biosynthesis of lantibiotic epidermin.
