Patent number: 11034220Abstract: A protective device including a flexible fabric shiftable longitudinally between different functional positions, and provided on opposite side edges with respective stiffening strips guided in a manner shiftable longitudinally in vehicle-mounted guide tracks. A pull-out profile extends transversely with respect to the longitudinal shifting direction of the fabric and is connected to an end region thereof. The pull-out profile is guided in the vehicle-mounted guide tracks by guide elements, and each stiffening strip is fastened on the end side to a respective guide element. Each stiffening strip has at least three receptacles provided one behind another in the longitudinal shifting direction, and the guide element is assigned at least three profiling portions spaced apart from one another in the longitudinal shifting direction and projecting into the receptacles in a form-fitting manner transversely with respect to the longitudinal shifting direction.Type: GrantFiled: June 27, 2018Date of Patent: June 15, 2021Assignee: BOS GMBH & CO. KGInventors: Günter Renz, Karl-Heinz Winter

Patent number: 5430746Abstract: A method of and a circuit arrangement for detecting synchronization of two word sequences between a measurement signal and a reference signal. The signals are applied to an exclusive OR-gate comparator whose output produces an error signal which is compared with an error signal shifted by one period. This comparison is effected by an exclusive OR-gate and in the case of coincidence, indicating that the measurement and reference signals are phase-shifted, a new synchronization is enabled. The output of the exclusive OR-gate is an error signal which is time-shifted in a shift register and multiplexer so that the time shifted bit sequence is compared with the bit sequence of the first error signal in a second exclusive OR-gate which is connected to an AND-gate for detecting coincidence and generating a further synchronization signal which is processed through counters, another AND-gate and a flip-flop to produce the synchronization signal which is applied to the reference pattern generated.Type: GrantFiled: November 8, 1993Date of Patent: July 4, 1995Assignee: Wandel & Goltermann GmbH & Co.

Patent number: 3965294Abstract: To check the bit-distortion ratio of a transmission line carrying bipolar PCM signals, converted from a binary to a balanced ternary code at the tramsmitting end and reconverted into binary signals at the receiving end, binary test words and identical reference words are simultaneously read out from storage at opposite ends of the line. The test words are converted into bipolar form, for transmission, and the received pulses are distributed according to polarity over a first pair of leads while the binary pulses of the reference words are distributed over a second pair of leads according to the conversion code used at the transmitting end. The pulse trains on corresponding leads are compared, bit by bit, in a deviation monitor whose output, in response to any mismatch, advances a reversible counter which is reverse-stepped by timing pulses of a cadence reduced by a frequency divider to a fraction of the bit rate.Type: GrantFiled: April 23, 1975Date of Patent: June 22, 1976Assignee: Wandel U.
