Abstract: Provided is a miniaturized inhalation device for inhaling at least one active ingredient through the nose, including: a U-shaped component and a first and second elongate reservoir portion which each have a cavity for receiving an active ingredient and being configured to be introduced into a nostril. The cavities each have an opening on the top side through which the active ingredient can exit from the corresponding cavity. The inhalation device also has a curved bracket portion which integrally connects the first and the second elongate reservoir portion and extends at least in a base region of the U-shaped component, and a self-holding mechanism to be held against the nose, and an integral clamping projection is arranged on the inside in the region of the first and the second elongate reservoir portion. A set comprising at least one inhalation device and one storage container may also be provided.

Abstract: A ball joint with a ball pin and a steel ball pin with a joint ball. The ball joint and ball pin are suitable for use when, for example, solid-on-solid friction predominates under high static pre-loading or high operational loads and with small joint movements. A portion of the surface of the ball pin has surface layer hardening in order to increase a fatigue strength of the ball pin. The ball pin and the ball joint, on portion of the ball pin without the any surface layer hardened, includes a nitrided layer as wear protection. The ball pin and the ball joint provide an advantageous combination of high fatigue strength, good corrosion protection and high wear-resistance. The nitrided layer of ball joints, previously only regarded as improving corrosion protection, also functions as a wear protection. Thus, these ball pins overcome the mutual exclusion between surface layer hardening and nitriding.

Abstract: A ball joint with a housing formed entirely by a cold forming method. The housing having an inner chamber for receiving the joint ball of a ball pin and an opening through which the ball pin extends, and a contact area on the outer surface area of the housing forms a seal with a bellows. A forming section of the housing secures the joint ball within the inner chamber such that the joint pall can both rotate and pivot. Following completion of the housing, the material displaced during the cold forming method creates the forming section of the housing. The method for producing a ball joint comprises the steps of producing a metallic housing blank with a thickening formed by compression, forming the outer contour of the housing by compression, shaping the inner contour of the housing through dishing, and using the displaced material for creating the forming section.

Abstract: A joint arrangement (8) is provided with a joint (15; 22), which can be stressed at least axially and on bending. The joint has an outer joint shell (17; 25) and an inner joint body (16; 23) that is movable in relation thereto. The joint axis (A1) is located at a spaced location (e) from the central axis (A2) located centrally in the joint (15; 22).

Abstract: A motor vehicle chassis has, on at least one axle, a control arm (7) guiding and/or carrying a wheel each and at least one wheel carrier (3) connected movably to this and to the wheel (5). A connection is provided between the control arm (7) and the wheel carrier (3) including a joint and/or bearing arrangement (8) designed such that at least one pin (12), which points rigidly upward from the wheel carrier (3), and which is held at a mount associated with the control arm (7) in an articulated manner, is associated with the wheel carrier (3).

Abstract: A joint housing (1) has a housing recess (2), a pivot pin (4), mounted in the housing recess. The pivot pin has a joint ball (3) provided with a surface protection. A pin section protrudes from a housing opening (18), with a bearing shell (5) arranged between the joint housing and the joint ball, and with a closing ring (7), which closes the housing recess of the joint housing and tensions the bearing shell arranged therein in the joint housing. The closing ring follows essentially with its inner contour the outer contour of the bearing shell due to a bevel or a radius formed. The closing ring (7) to be inserted into the joint housing is fixed in its position in the joint housing (1) and has a sealing lip (17) which is in contact with the joint ball (3) under elastic pretension on the side of the housing opening (18) through which the pin section of the pivot pin (4) protrudes from the joint housing (1).

Abstract: A ball-and-socket joint is provided with a joint housing which is open on at least one side with a housing recess, with a joint pin mounted in the housing recess with its joint ball provided with a surface protection. A pin section projects from a housing opening. A bearing shell is arranged between the joint housing and the joint ball. A sealing bellows is provided between the joint housing and the joint pin. A sealing element, which is under elastic pretension in sliding contact with the joint ball, is arranged between the joint housing and the joint ball.

Abstract: To improve the corrosion protection at the connection site of the sealing cuff and the ball pivot, it is proposed, in a design in which the sealing cuff engages with an edge profile in a complementary profile of a retaining ring rigidly attached to the ball pivot, that at least the part (12) of the retaining ring (10) which is supported by the edge of the bearing lug (6) consists of a material whose value in the electrochemical series is lower than that of the material of the bearing lug (6) and of the ball pivot (2). By this construction the material of the retaining ring acts as an electrolytic sacrificial anode.
