摘要： A known servo-drive including a stator which is formed with two-component design or the exciter winding has to be attached directly to the stator, which is associated with a costly production method. The new servo-drive is to permit easy and cost-effective manufacture with favorable actuation properties. The stator of the servo-drive includes in the region of the poles, weak points which are formed either by recesses or by gaps. An induction core includes a winding which is inserted into a yoke constructed on the stator by which a magnetic field can be induced in the stator. The alternating combination of sheet-metal laminas having gaps and recesses permits the torque/rotary angle characteristic of the servo-drive to be optimized with favorable production properties. The servo-drive for rotary angle adjustment of an actuator is used for example to control the opening cross-section of a medium-conducting flow line in internal combustion engines for the purpose of controlling idling speed.

摘要： L-Thienylalanines are prepared via the hydantoin or the azlactone route. The starting substances used for the biotransformation are 2-hydroxy-3-thienylacrylic acids. The innovative step consists in the transamination of the enol form of the 2-hydroxy-3-thienylacrylic acids to give L-thienylalanines with the aid of biotransformation. The transaminiation is carried out in the presence of L-aspartic acid or L-glutamic acid as amino donor.

摘要： An apparatus for governing the idling rpm of an internal combustion engine, in order to control a quantity of operating fluid to be delivered to at least two flow lines of the engine. According to the invention, the first valve closing member and the second valve closing member are disposed axially displaceably relative to one another and coupled via a slaving device in such a way that in the closing position of the first valve closing member, the second valve closing member is likewise closed, and the second valve closing member is adjustable in the valve opening direction only after attainment of a predetermined opening position of the first valve closing member. The closing properties of the apparatus can be adapted as required by means of the selection of the disposition and design of the springs that act upon the valve closing members. The apparatus is especially suitable for governing the idling rpm of a mixture-compressing internal combustion engine with externally supplied ignition, by controlling a quantity of operating fluid that is deliverable to the engine via a fuel metering device and an intake conduit.

摘要： A method for positionally securing two components together, in which a hollow body is introduced into the two components. Once the final position of the components relative to one another has been established, the hollow body is driven directly into the second component with the application of axial pressure and sonic energy. The method is suitable for employment with thermoplastic components whose relative position to one another is known beforehand, an example being in the assembly of housing parts of a rotary adjuster for controlling a flow cross section in internal combustion engines.

摘要： A rotational control device for the setting of angles in actuators, in particular of a restricting device used for determining the flow cross-section in a flow line for internal combustion engines, has an electrical setting motor with a two-pole status and a two-pole permanent magnet rotor. To obtain a robust setting motor, which is technically easy to manufacture in a compact construction, the stator poles are designed as claw poles and the stator winding is located as a toroidal coil in a ring space formed by the claw poles and a ring casing which is coaxial with these, for the magnetic return path. The stator winding is energized by a d.c. supply, with reversible current direction. The magnetic resistances in the magnetic return path and across the claw poles are calibrated such that in the event of a currentless stator winding, the permanent magnet rotor engages in the pole gaps between the claw poles.
