摘要:
A fastener for fastening a component having a mounting hole has an essentially U-shaped clamping region that at least partially grips around the component and has two opposing legs that are connected together as a single piece by a connecting region. The legs are provided with through holes that serve to accommodate a pin or stud that passes through the mounting hole of the component. A nut is attached to a first leg on the side facing away from the second leg such that the connection between the first leg and the nut can be released by a separating force acting on the nut.

A plastic clip for fastening an article in the region of an end face of a flat workpiece comprises a base section, including a first and a second leg extending from the base section to form a U shape, and a fastening section connected to the base section and operable to fasten the article to the clip. The base section and the legs are made of a relatively hard plastic material and the legs can be elastically expanded relative to one another in order to accommodate the workpiece between their inner sides. An anti-slip section made of a relatively soft plastic material is provided on at least one of the inner sides.

The present invention relates to a process for preparing sulfuric diamides of the general formula I R1R2N—S(O)2—NH2 (I) in which R1 and R2 are each independently a primary alkyl radical having from 1 to 8 carbon atoms, a secondary alkyl radical having from 3 to 8 carbon atoms or a cycloalkyl radical having from 5 to 8 carbon atoms, or, together with the nitrogen atom, form a 5- to 8-membered, saturated nitrogen heterocycle which, as well as the nitrogen atom, may have a further heteroatom selected from O and S as a ring member, where the nitrogen heterocycle is unsubstituted or may have 1, 2, 3 or 4 alkyl groups having in each case from 1 to 4 carbon atoms as substituents. The process comprises the following steps: i) the reaction of a secondary amine of the formula II R1R2NH (II) in which R1 and R2 are each as defined above with sulfuryl chloride in an inert solvent, especially an aromatic solvent, in the presence of a tertiary amine to give a sulfamoyl chloride of the formula III R1R2N—S(O)2—Cl (III) in which R1 and R2 are each as defined above, and ii) reaction of the sulfamoyl chloride of the formula III obtained in step i) with ammonia, the sulfamoyl chloride of the formula III being used in step ii) in the form of the solution obtained in step i) in the inert solvent, especially the aromatic solvent.

A viscous clutch (30; 30′) includes a stationary journal bracket (32; 32′) defining a mounting shaft (32-1; 32-1′), an output member (34; 34′) rotatably supported on the mounting shaft about an axis (A), an input member (34; 34′) rotatably supported on the mounting shaft about the axis, and a working chamber (50; 50′) defined between the input member and the output member to selectively transmit torque there between when a shear fluid is present. The mounting shaft extends axially through the viscous clutch from a front face (62; 62′) of the viscous clutch to a rear face (56; 56′) of the viscous clutch, with the rear face defining a mounting surface for mounting the viscous clutch at a mounting location. The front and rear faces are located at opposite sides of the viscous clutch and face in opposite directions.
