Abstract: In a method for winding round the button stem of a button sewn by a sewing thread to an article of clothing, in which a winding thread made from an elastomeric plastic is wound on under tension onto the thread bundle formed from sewing thread between the button and the article of clothing, in a simpler manner a reliable fixing of the winding thread end is brought about in that the winding thread, following the wrapping of the thread bundle, is drawn off the stem in a direction roughly at right angles to the axis with a tension increased to beyond its yield point, before the separation thereof at the button stem. The thread end extending over several coil turns is firmly fixed between the previously placed coil turn as a result of its diameter greatly reduced by complete elongation. Two embodiments of an apparatus for performing the method are also described and the apparatus is constructed as a compact, esily handleable hand-operated device.

Abstract: There is a method of making a threaded hole in a workpiece 15 whereby a core hole 9 is produced in the workpiece 15 with a combination drilling and thread milling tool 14 being advanced axially and threads are generated in the wall of the hole by a helical motion of the combination tool 14. It is desirable that the combination tool should be capable of making core holes whose diameter is greater than the drilling edge outer diameter of the combination tool. This is achieved in that the combination drilling and thread milling tool 14 in making the core hole 19 is moved on a helical path 11, 12 relative to the workpiece 15. Depending on the setting of the radius of the helical path, a different size inner diameter of the core hole is obtained.

Abstract: The invention relates to torsion vibration dampers in the power transmission path of a motor vehicle with an internal combustion engine, the coil thrust springs used being particularly in the case of a considerable length in proportion to their diameter, already precurved prior to fitment into their final position. This facilitates fitment and makes it possible to influence the development of friction force as the rotary speed increases.

Abstract: A process and an assembly for producing force-locking connections between tubular members inserted one into the other or for attaching elements slid onto tubular members, by permanent radial expansion of several sleeves slid into the tubular members in a coaxial arrangement. The sleeves are filled with a pressurized fluid and pistons are inserted into end apertures of the sleeves. The apertures of adjoining sleeves which face each other are closed by a single piston. Finally, by bringing the pistons closing the outwardly facing apertures of the outer sleeves closer together, the internal pressure is increased.

Abstract: A process for closing an evaporation chamber of an electrically heated steam iron having a sole member, an evaporation chamber fixedly connected to the sole member and closable by a lid, said evaporation chamber having a vertical steam chamber wall with a top surface on which rivets with a substantially frustoconical rivet base are cast, and the lid having rivet holes associated with each rivet, the cross-section of each rivet hole being equal to or greater than the cross-section of the base of the rivet associated with the rivet hole, the process including the steps of: placing the lid on the top surface of the steam chamber wall, subjecting a rivet-hole edge portion of each rivet hole to pressure of a ring stamp, increasing the pressure of the ring stamp until the flow limit of the lid material is exceeded, this flow limit being lower than that of the material of the sole member, releasing the ring stamp after permanent deformation of the rivet-hole edge portion, clinching the rivet, and deforming the free

Abstract: In a syringe for ultrasonically aided penetration of arterial or venous vessels the transmitter and the receiver are arranged in the piston. This simplifies manipulation and, particularly if a physiological saline solution is simultaneously injected to directly couple the ultrasound to the soft parts surrounding the vessel, enables vessels even in anatomically difficult positions to be localized simply and without the danger of complications.

Abstract: A fluid dispensing valve is made up of a plural part valve body enclosed by an elastomeric sheath sealed at spaced locations to the outside surface of the valve body. Fluid is dispensed out of a container through the dispensing valve. The arrangement of the valve body parts and the sheath permit flow out of the valve but prevent any flow back into the container. As a result contamination can not flow back through the valve into the container.

Abstract: A differential unit comprises a differential carrier (12) supported in a housing (11) for rotation; output elements (16, 17) differentially rotatable relative to the carrier and connected to respective output shafts; differential gears connecting the output elements; and a friction assembly comprising respective plates (22, 24) rotationally fast with elements of the differential, the friction assembly being axially loadable to restrict the differential rotation of the output elements. An actuating mechanism for loading the friction assembly comprises abutment and actuating rings angularly and axially movable relative to one another, with cam surfaces provided by circumferentially extending variable depth grooves in the rings with balls therebetween engaging the grooves. In order to avoid unintentional restriction of the differential action, the grooves and balls are arranged so that no frictional self-inhibition of relative movement between the abutment and actuating rings can occur.

Abstract: A viscous coupling comprises first and second torque-transmitting members (1, 2) rotatable relative to each other, defining an operating chamber at least partially filled with a viscous fluid; a plurality of first plates (16) engaging and rotationally fast with the first torque-transmitting member; a plurality of second plates (17) interleaved with the first plates, and rotatably mounted on the second torque-transmitting member (2); clutch plates (18) engaging the second torque-transmitting member and disposed alternately with the second plates; a control member (9) operable to compress the clutch plates axially to clamp the second plates between them, and seals (14, 15) operable between the first torque-transmitting member and the control member and between the second torque-transmitting member and the control member, at sealing surfaces (9A, 2A) which are substantially of equal effective diameter to one another.

Abstract: A viscous coupling having outer plates which are provided with index recesses which serve to assemble the outer plates in a specific way relative to each other, depending on the respective application. If the outer plates have to be assembled in the housing with the apertures being aligned inphase relative to each other, the torque transmitting capacity of the coupling is lower than in those cases where the slots are circumferentially offset relative to each other in the housing, thereby forming a kind of labyrinth, in which case the viscous coupling achieves a 100% torque transmission because it may be transferred into the hump mode.

Abstract: A fluid dispensing valve is made up of a valve body laterally enclosed by an elastomeric sheath. The valve body is connected to a container from which fluid is dispensed through the valve body. The valve body has an inlet passage for flowing the fluid from the container to a space between the elastomeric sheath and an outer surface of the valve body. An outlet passage through the valve body, spaced angularly from the inlet passage, has an opening through the outer surface of the valve body covered by the elastomeric sheath, so that fluid pressed out of the container can flow between the elastomeric sheath and the outer surface to the outlet passage and then be dispensed from the valve. The valve body can be a flat disk-like member.
