Abstract: An earth-leakage circuit breaker has a totalizing current transformer, a magnetic trip device and switchgear with main current contacts for the main leads. A current-signal generator, a current sensor, a time-signal generator and an electronic timer wherein the switching value and response time of the circuit breaker are measured at predetermined intervals, compared with reference switching values and response times and, if these reference values are exceeded, an alarm is promptly given. During the measurement, a locking device prevents the main current contacts from opening and/or when predetermined limiting switching and response times are exceeded, the locking device opens the main current contacts and subsequently acts as a lock preventing the contacts from closing again, which is equivalent to fail-safe behavior. In addition, the switching value of the circuit breaker is multiplied by its response time and the product, which may exceed a particular constant value, is used for monitoring purposes.

Abstract: In a textile machine including needles for forming a plurality of warp yarns into stitches and a guide bar for guiding the warp yarns to the needles, the guide bar is constructed to lay warp yarns in patterns without moving the entire guide bar by providing the guide bar with at least one guide block movable relative to a fixed point on the guide bar. Each of the guide blocks includes a respective guide for one or more warp yarns. At least one guide block is connected in a chain configuration to at least one distance altering element, and the distance altering element is controlled to variably alter the distance between the guide block and the fixed point.

Abstract: Identification card, including a card body, an integrated semiconductor circuit being mechanically inserted and protected in the card body for storing data to be read-out and read-in in changed form, a receiving antenna device, a rectifier circuit connected to the receiving antenna device, a filter circuit connected between the rectifier circuit and the integrated semiconductor circuit. The rectifier and filter circuits generate a supply voltage for the integrated semiconductor circuit from an energy field, a microwave transmitting antenna connected to the integrated semiconductor circuit, and a transmitter connected to the transmitting antenna.
