Abstract: A passenger transport system includes a bus system transferring data between a central control unit and a plurality of field devices. In a failure detection method, the field devices are configured in an unbranched chain configuration and the control unit transmits a test telegram to a first field device to start a monitoring cycle during which each field device receiving the test telegram forwards the test telegram to a next field device in the chain. During the monitoring cycle, the control unit monitors a communication between the field devices occurring via the bus system, in order to detect when a field device does not forward the test telegram. A data volume transmitted via the bus system during the failure detection method is significantly reduced in comparison to conventional failure tests such that failures can be recognized more quickly and/or simpler hardware and/or software can be used.

Rail-based traveling gears are connected to the gantry supports of the framework via articulated connections for supporting the framework on rails. Balancers connected to the gantry supports via articulated connections and at least four steerable tire-based traveling gears are connected to the framenwork via the balancers. The at least four steerable tire-based traveling gears are symmetrical to a longitudinal axis and a transverse axis of said handling machine.

Abstract: Upon excitation of the electromagnet, a clapper armature is pulled into an operating gap, being increasingly additionally attracted by the pole of an electromagnet yoke leg.The motional plane of the clapper armature extends perpendicularly to the plane of the magnetic flux of the yoke structure of the electromagnet.

Abstract: The invention relates to a print hammer bank of electromagnetic print hammer actuators in modular design of the type which includes a plurality of actuators each of which comprises a stator formed in two halves, each half including an electromagnet and a plurality of pole pieces, and means for positioning the stator halves relative to each other so that the ends of the pole pieces of the two halves are spaced apart in pairs so as to form a plurality of aligned operating gaps. The armature elements are designed so that the volume of each armature element is of the order of the volume of the associated operating gap.

Abstract: A high-speed reciprocating actuator, of the type used as a print hammer in high-speed printers or for operating valves or the like, is made more compact and efficient by the arrangement of a stator yoke. The stator yoke provides a series of aligned magnetic gaps that cooperate with armature bars contained in a reciprocating ram member. These gaps are made part of a plurality of independent flux conducting loops. One or more activating coils pass through each of the loops to induce magnetic flux when ram actuation is desired.

Abstract: An electromagnetic actuator for performing an individual stepping, switch or impact movement consists of an electromagnetic actuator and a pivoted or rocking armature moving. The rotational design of the electromagnetic actuator enables only one excitation coil to serve a plurality of magnetic gaps.

Abstract: Bank for accommodating adjacent ram units. Each of these consists of a flat, narrow frame. A tongue-shaped ram, driven by an electromagnetic actuator, extends in a recess of the frame. For accommodating and guiding the individual print ram units, the bank is provided with a receiving bar and a comblike holding bar between which the frames are arranged. Extension pieces of the lower frame elements can be accommodated by slits in the receiving bar. The upper frame elements are held in recesses of the comblike holding bar. The tongue-shaped rams are laterally guided by the electromagnetic actuators which are arranged on both sides of the frame and are aligned to each other.

Abstract: An electromagnet consists of two essentially symmetrically designed magnetizable E-shaped yoke halves each embraced by a coil. The facing pole ends of the yoke halves form three aligned operating gaps. Between the operating gaps a tongue-shaped ram is arranged which is shiftable in the direction of the line of alignment of the operating gaps. The cross-section of the ram is adapted to the area of the operating gaps. The ram comprises cuboid-shaped armature bars of magnetizable material. The armature bars are geometrically designed in such a manner that their volume is on the order of magnitude of the operating gap volume. In the original position of the ram the armature bars are essentially positioned in front of the operating gaps of the electromagnet. Upon excitation of the electromagnet, the armature bars are pulled into its operating gaps, being accelerated in the process.The windings of the coils exciting the yoke halves are essentially positioned between the E-legs of the yoke halves.

Abstract: Bank for accommodating adjacent ram units, each of which consists of a flat, narrow frame. An electromagnetic actuator for a ram, which is guided in two bores of the frame, is positioned in a recess of the latter. For accommodating and guiding the individual ram units the bank has a substantially U-shaped cross-section. At least on one of its two ends, the frame of each ram unit is provided with a flexible pin arranged between two frame sections. The frames are detachably mounted between the U-sections of the bank. Both U-sections have recesses for positively and/or non-positively accommodating the front or rear frame part and the pin, respectively.

Abstract: An electromagnetic ram actuator, the electromagnet of which consists of two symmetrically designed magnetizable yoke halves. The facing pole ends of the yoke halves are in each case essentially semicircularly recessed, forming two aligned essentially circular operating gaps. Between the operating gaps a ram is arranged which is shiftable in the direction of their line of alignment and whose cross-section is adapted to the area of the operating gaps. The ram comprises two armature disks of magnetizable material and a spacer element arranged therebetween consisting of predominantly non-magnetizable material. One armature disk is associated with each operating gap. The armature disks are geometrically designed in such a manner that their volume is of the order of the operating gap volume. In the starting position of the ram the armature disks are positioned in front of the operating gaps of the electromagnet in its non-excited state.

Abstract: For producing a transducer access opening in a stack of rotating flexible magnetic record disks, a co-rotating part axially deflects the peripheral edges of selected disks for partially axially separating same. The co-rotating part may take the form of a thin disk, several thin disks, or shaped as a roll. The axis of the roll is obliquely inclined against the disk pack rotational axis. The roll has a resilient surface such that, after the roll has been inserted into the disk pack, the flexible disks move up the outer surface of the roll to be deflected.

The cover portion has a recess extending transversely of the electrodes and retains an elastic, nonconductive, and deformable tube frictionally restraining the electrodes, yet allowing electrode advancement as required.
