The individual components of the front housing part can be assembled without screws.

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: A process and apparatus for leak-proof sealing of a metallic capsule closed by a stopper and joining the capsule to a metal cable by arc welding, wherein a capacitor is charged, the capsule with a striking tip at one end or the stopper with an ignition point and the cable are clamped at their ends, connected to the terminals of the capacitor, moved together and welded together by discharging of the capacitor with the formation of an arc.

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 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: 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 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.

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 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: 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 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 method and an arrangement for regulating the thickness of rolled strip utilizing the gauge meter method and for compensating irregularities caused by roll eccentricities, wherein the size of the roll gap, the rolling force and the stand modulus are taken into consideration. The method includes separating a disturbance signal due to the eccentricities of rolls from an actual rolling force signal, identifying the disturbance signal obtained in this manner by determining its transmission function, subsequently computing the regulating parameters in dependence upon the determined disturbance signal transmission function and with the aid of a regulating synthesis method. A compensation signal is determined from the disturbance signal and the corresponding regulating parameters in an adaptive regulator for compensating the irregularities due to eccentricities. The compensation signal is introduced in a position regulating circuit.

Abstract: A method and apparatus are disclosed for achieving and maintaining an inert atmosphere as oxygen-deficient as possible in a treatment chamber, having a reaction zone, particularly an irradiation chamber, traversed by a length of material, wherein the length of material is supplied to the chamber through an inlet channel and conducted from the chamber through an outlet channel. A circulating inert gas stream, which detaches the entrained gas boundary layer held by the material, is moved countercurrently to the length of material in the inlet channel and is supplemented in a controlled manner with fresh inert gas in such amount that a given maximum oxygen concentration is not exceeded in the reaction zone and the flow rate of the inert gas stream is controlled, so that the pressure before the exit gap of the outlet channel is the same or slightly higher than the surrounding pressure.
