  • Patent number: 11916345
    Abstract: A connection terminal for connecting a conductor is formed as a direct plug-in terminal and includes a clamping spring arranged in a housing. The clamping spring includes a resilient clamping leg which can move into an open and locking position by pressing down an actuating device. The housing contains a conductor insertion channel for insertion of the conductor into a clamping point between the free end of the clamping leg and a busbar. The actuating device includes a pressing element and a pivoting element which interacts with the pressing element at least when the clamping point is being opened. At least one release device is provided for releasing the locking state of the clamping leg of the clamping spring. The release device is designed in such a way that the locking position can be released again by the action of the conductor on the release device when it is inserted, wherein the pivoting element acts on the pressing element and the pressing element acts on the clamping leg.

  • Patent number: 10340813
    Abstract: Multi-phase electronic power converter (50) for outputting multi-phase alternating current, wherein for every phase the current converter (50) comprises a power output (52) controlled via at least two semiconductor switches (51) connected in a half-bridge circuit, wherein the electronic power converter (50) has a control device (53) which is configured for processing a target value signal of the control device (53) supplied as an input signal, each in the form of a bit stream (1, 2, 3, 30, 31, 32) of one or more bits for every phase, characterized in that the control device (53) is configured by means of space-vector modulation to generate actuation signals (P1, P2, P3) of the semiconductor switches (51) in relation to the bit streams (1, 2, 3, 30, 31, 32) supplied as an input signal.

  • Patent number: 7451020
    Abstract: The invention relates to a control system (1) for a vehicle provided with an electronically controlled drive train (2) which comprises a steering system (6), a braking system (7) and a transmission unit (4). An operating unit (10) generates a motion vector (BV) based on a driver's wish (FW), from which control signals (SS) are generated by a control unit (12) for controlling the drive train (2). In order to simplify maneuvering, more particularly reversing, a trajectory calculator (13) is provided, said trajectory calculator calculating the trajectory of movement for the situation and position of the vehicle (3) on the basis of actual values that are detected by a status and position determining device (14) and on the basis of set values that can be inputted by means of a target input device (15).

  • Patent number: 6314771
    Abstract: A device for applying a patterning liquid to a web, particularly to a carpet web, has an exit slit with a plurality of valves distributed over the width of the web and arranged ahead of it, which can all be activated independent of one another, and which each supply the patterning liquid to a specific width section of the application slit. The valves are located as close as possible to the exit location so that the segment from the closing location of the valves to the exit location is as short as possible.

  • Patent number: 6195824
    Abstract: A process for dyeing a textile web, in which the textile web is continuously guided through a trough that contains the dye bath, and subsequently passes through a pair of squeezing rollers. The line force of the pair of squeezing rollers is adjusted as a function of the length of textile web (L) that has passed through, with the aim of achieving a uniform amount of dye applied over the length of the textile web, per surface unit of the textile web.

  • Patent number: 5878974
    Abstract: A device to wind and unwind a textile web onto and from a spool, when it comes into or out of a wet-processing group is disclosed. The device includes a guide and tension roll supported at the free ends of winding arms and resting on the spool. A moisture-extraction device in the form of a suction pipe is mounted immediately upstream of the guide and tension roll. The web may thus be wound onto the spool with a relatively low moisture content.

  • Patent number: 4713531
    Abstract: A heating element for textiles is disclosed, which comprises a plane textile element and, combined with this, metal conductors, which can be connected to a source of electrical current and which oppose the electrical current flowing through them with a heat-producing resistance. As resistance elements, the conductors have metallic fibers or filaments with a denier like that of natural or synthetic textile fibers. The metallic fibers or filaments have an average cross sectional thickness of about 8 to about 24 microns.
