    Abstract: A wire is passed over the suction breast roll between the formed paper web and the doffer belt or the previously formed paper webs and doffer belt. The doffer felt is disposed in an unencumbered fashion over each of a plurality of consecutive suction breast rolls. The wire is removed from the web at a downstream point outside the dewatering influence of each breast roll. Stripping of the wire from the paper web is aided by various suction devices or couch rolls at this latter point.

    Abstract: In a wet press for dewatering a web of material, for instance a web of paper, a contact pressure device presses against a rotating roll and exerts a pressure which increases in the travel direction of the web of paper. For this purpose, several rows of contact pressure elements are arranged sequentially in the travel direction of the web of paper. In each row the contact pressure elements are arranged side by side transversely to the travel direction of the web of paper. In order to circumvent a differential dewatering at the location of the contact pressure elements and at the gaps between the contact pressure elements of a row, the contact pressure elements of successive rows are shifted or staggered in relation to one another transversely to the web of material such that they mutually overlap. This prevents the arisal of strips in the paper being processed.

    Abstract translation: 在用于对诸如纸幅的材料网进行脱水的湿压机中，接触压力装置压靠旋转的辊并施加在纸幅行进方向上增加的压力。 为此，在纸幅的行进方向上顺序地设置有数排接触压力元件。 在每排中，接触压力元件横向于纸幅的行进方向并排布置。 为了避免在接触压力元件的位置处和在一排的接触压力元件之间的间隙处的差分脱水，连续行的接触压力元件相对于彼此横向于材料幅材的彼此相对错开或交错 使它们相互重叠。 这样可防止正在处理纸张中的条状物。

    Abstract: The wet section of a twin wire papermaking machine is provided with an open forming roll at the lower wire and with the combination of a suction box at the lower wire and a vacuum suction box at the upper wire. Furthermore, by selecting the elevational position or level of the individual wire sections there can be obtained particularly advantageous conditions for the operation of the papermaking machine throughout a wide field of application, especially heavy types of paper at relatively low operating velocities of the papermaking machine. Gap-former and hybrid-former constructions of the papermaking machine are possible.

    Abstract: The de-watering apparatus for a two-wire paper machine is constructed in such a manner that following the convergence of both wires, firstly, a uniform pressure at a forming roll is exerted on the suspension layer located between the wires. Subsequently, both wires pass de-watering rails which may be located in the upper and/or the lower wire. In this case, an under-pressure is exerted at least at the rails located in the upper wire. At least one further de-watering member then follows before both wires are separated again. The de-watering apparatus can also be used after a preliminary de-watering section, for example an endless wire, and also in the direct vicinity of a head box.

    Abstract: A ferroelectric memory comprises a plurality of memory cells and circuitry to sense data thereof. Power supply decoupling circuitry may decouple supplies of the memory device during a portion of reading data. Additionally, ferroelectric domains of the memory cells may receive a series of polarization reversals to improve domain alignment and malleability. To drive reference cells of the memory with such polarization reversals, a multiplexer may be configured to swap a data bitline with a reference bitline so that reference cells may be accessed as regular data cells. While reading a ferroelectric memory, a self-timer circuit may monitor characteristics of the ferroelectric material and adjust an integration duration for a sense amplifier based on the monitored characteristics. A sampling-comparator may sample a signal related to the ferroelectric material at one instant, which may then be used subsequently thereafter by the self-timer circuit to influence an integration duration of the sense amplifier.

    Abstract translation: 铁电存储器包括多个存储器单元和用于感测其数据的电路。 在读取数据的一部分期间，电源去耦电路可以解耦存储器件的电源。 此外，存储器单元的铁电畴可以接收一系列极化反转以改善畴对准和延展性。 为了以这样的极化反转来驱动存储器的参考单元，可以将多路复用器配置成与参考位线交换数据位线，使得参考单元可以作为常规数据单元被访问。 在读取铁电存储器的同时，自拍定时器电路可以监测铁电材料的特性，并且基于所监视的特性来调整感测放大器的积分持续时间。 采样比较器可以在一瞬间对与铁电材料相关的信号进行采样，随后可以由自拍定时器电路使用该信号来影响读出放大器的积分持续时间。

    Abstract: A sensing circuit. The circuit includes an integrator to sense charge release from a passive electronic device and a comparator to interpret the charge release as one of at least two data states. The circuit also includes a compensation module to generate a compensation signal as needed and a self-timing module to adjust timing of the integrator sensing based upon a predefined voltage level.
