摘要： A signal isolating device for an input digital signal has a first photo-coupler which is activated by the differential pulse produced at the leading edge of the digital signal and a second photo-coupler which is activated by the differential pulse produced at the trailing edge of the digital signal. A positive feedback system is connected in push-pull fashion with the photo-couplers for producing an output digital signal that corresponds to the input digital signal. The positive feedback system may be implemented by a buffer that includes a resistor for keeping the buffer in a stable state even when both of the photo-couplers are non-conductive.

摘要： A dual processor computer system with error checking that stops immediately when a discrepancy is detected between the two processors. The system includes a first processor for executing a series of instructions including input/output instructions. A second processor executes the same instructions independently of and in synchronization with the first processor. Both processors have a processor independent bus interface. All significant processor address, data, and control signals are connected to all peripheral devices by a processor independent I/O bus. A comparison circuit detects discrepancies in the operation of the two lock step processors and provides a signal that immediately stops operation of the processors when an error is detected. Each processor is connected through its associated processor independent bus interface to the comparison circuit and the first processor is also connected through its interface to the I/O bus. The I/O bus is independent of the processor type, clock rate, and peripherals chosen in the construction of the computing system. This independence allows the computing system to be upgraded with faster processors and newer peripherals, without having to redesign the error checking circuitry.

摘要： A control station for use individually or as an element of a distributed process control system has an improved high frequency isolation and grounding system incorporating a "Chomeric" conductive foil tape on both the cabinet front and back walls as well as on the doors and a V-shaped "Chomeric" conductive gasket placed between the cabinet wall and the door in the area of the conductive tape to insure proper sealing of the door and opening to eliminate all RFI (radio frequency interference) problems and meet European standards for RFI cabinet emissions. This cabinet also has a grounding system comprising a large area swing clip for removing the door as well as a hybrid grounding circuit to eliminate ground potential differences due to geological variations found in different parts of the landscape since the signals reaching the cabinet may originate at remote locations up to a mile or more from the cabinet. The circuit accomplishes this by grounding the DC signals at only one end while the AC signals are grounded at both ends.
摘要翻译：单独使用或作为分布式过程控制系统的一个元件使用的控制站具有改进的高频隔离和接地系统，其在柜的前壁和后壁以及门和门上都包含“Chomeric”导电箔带，V 在导电胶带的区域内放置在柜壁和门之间的“Chomeric”导电垫圈，以确保门和开口的正确密封，以消除所有RFI（射频干扰）问题并符合欧洲RFI机柜排放标准。该柜还具有接地系统，该系统包括用于移除门的大面积摆动夹以及混合接地电路，以消除由于在景观的不同部分中发现的地质变化而导致的地电位差，因为到达柜的信号可能源自远程距柜体一英里或更远的位置。该电路通过仅在一端接地直流信号而交流信号在两端接地来实现这一点。

摘要： A digital implementation for a carrier detector. The detector determines if the carrier frequency at any instant is within a predetermined frequency band. The detector further determines if the detected frequency remains within the predetermined frequency band for a predetermined period of time. The detector also provides an indication that there has not been any loss of carrier for another predetermined period of time.

摘要： Es wird ein magnetisch-induktiver Durchflußmesser vorgeschlagen, der ein Meßrohr, eine Elektromagneteinrichtung mit wenigstens einer elektrischen Leiterschleifenanordnung zur Erzeugung eines das Meßrohr quer zu dessen Rohrlängsachse durchsetzenden Magnetfeldes und wenigstens zwei Meßelektroden (9,9') aufweist, die quer zur Längsachse des Meßrohres einander gegenüberliegend derart angeordnet sind, daß mit ihnen eine aufgrund der quer zu dem Magnetfeld verlaufenden Strömung einer das Meßrohr durchfließenden Flüssigkeit induzierte Meßspannung abgegriffen werden kann. Die erfindungsgemäße Besonderheit besteht insbesondere darin, daß die elektrische Leiterschleifenanordnung (7,7') aus einem elektrisch leitfähigen, an der Innenseite oder an der Außenseite des Meßrohrkörpers (5) angebrachten Blechteil besteht, das mit wenigstens einem Ausschnitt (13) als innenliegende Begrenzung des um den Ausschnitt herum in dem Blechmaterial verlaufenden Leiterschleifenstrompfades versehen ist.
Der erfindungsgemäße Durchflußmesser weist einen einfachen Aufbau der Elektromagnet-Einrichtung auf und ermöglicht eine Rechteck-Magnetfelderregung mit vergleichsweise hoher Frequenz selbst bei Meßrohren mit großen Nennweiten (z.B. DN > 300), da die Leiterschleifenanordnung eine kleine Induktivität besitzt.
摘要翻译：一种具有测量管的磁感应流量计，具有至少一个电导体环路装置的电磁体装置，用于产生与其纵向轴线成直角穿过测量管的磁场，以及至少两个测量电极另一个与测量管的纵向轴线成直角，使得它们可以用于分离由流动通过测量管的液体流动而导致的测量电压，该测量电压与磁场成直角地流动。电导体环路布置具有导电性金属片，该导电性金属片部装配在测量管体的内侧或外侧，并且设置有至少一个切口，作为导体环路电流路径的内边界围绕钣金材料的切口。流量计具有更简单的电磁装置的设计，即使在测量具有大的公称直径（例如DN> 300）的管的情况下，由于导体环路布置具有低电感。
