    • In an ergonomic keyboard comprising at least two housing sections with separate key pads wherein the two housing sections are interconnected by a joint permitting pivoting and also tilting of the two housing sections relative to each other, the joint comprises a coil spring which extends between, and is connected to, the two housing sections at the end of the housing sections remote from an operator so as to form a universal joint between the two housing sections, and a sector-shaped indexing plate is mounted with one end firmly to one of the housing sections and extends into the other housing section so that it bridges any gap formed between the two housing sections when they are pivoted apart, and the other housing section has a guide pin projecting into a partial circular guide slot formed in the indexing plate and having a center of curvature coinciding with the universal joint pivoting center for guiding the two housing sections relative to each other.

    • In a device for ascertaining the actual feed transmittted by an feed devicef an industrial sewing machine to a material to be sewn, in which the number of the threads moved across a sensor arrangement is counted and the feed is calculated from the previously detected thread density, it is provided, for obtaining an exact thread count which is as independent as possible of the orientation of the sewn web, to place ahead of the photocell (10) of the sensor arrangement a rotating slit diaphragm (7) with at least one radially extending parallel limited slit (8). Preferably a second, rotationally adjustable, but fixed slit diaphragm (5) is provided, having slits (6) opening across a set angular sector, the rotatitng slit diaphragm (7) having a larger number of slits (8). Because of this the required rpm of the slit diaphragm (7) can be reduced. To avoid errors caused by the pattern of the material it is possible to operate in the relatively longer wave infrared spectrum.

    • The invention provides an arrangement for determining the speed and rotor position of an electric machine, which arrangement consists of a tachometer generator having a permanent-magnet-excited rotor and a coaxially arranged rotor position transmitter which has a rotor body equipped with permanent magnets. Around the circumference of the rotor body magnetic-field sensitive sensor elements are arranged. A compact assembly of the tachometer generator and rotor position transmitter without detrimental mutual interference is possible by the provision that first permanent magnets magnetized in the tangential direction are arranged centered to the pole gaps of the tachometer generator rotor at the rotor body in such a manner that the sides of two adjacent permanent magnets facing each other have the same polarity as the magnet pole extending between the respective pole gaps of the tachometer generator rotor. Furthermore at least one second permanent magnet magnetized in the direction of an axis of rotation is arranged on the side of the rotor body adjacent to the tachometer generator rotor, centered relative to each two first permanent magnets in such a manner that its side facing the tachometer generator rotor has the opposite polarity (N or S, respectively) as the opposite magnet pole of the tachometer generator rotor.
    • 本发明提供了一种用于确定电机的速度和转子位置的装置,该装置由具有永磁激励转子的转速计发生器和同轴布置的转子位置变送器组成,转子位置传感器具有装备有永磁体的转子体。 围绕转子体周围设置磁场敏感传感器元件。 转速计发生器和转子位置变送器的紧凑组件可以通过设置在转子主体处以沿切向方向磁化的第一永磁体以转子座发电机转子的极间隙为中心的方式,使得转子体发电机和转子位置变送器之间不会有相互干扰, 两个相邻的永磁体彼此面对的侧面具有与在转速计发电机转子的各极间间延伸的磁极相同的极性。 此外,在旋转体的方向上磁化的至少一个第二永久磁体被布置在转子体的与转速计发生器转子相邻的侧面上,相对于每两个第一永久磁铁居中,使得其面向转速表 发电机转子具有与转速计发电机转子的相对磁极相反的极性(分别为N或S)。
