    • A method for rudder roll stabilization having two-feedback-path nonlinear dynamic compensation (NDC) is described. The high-order, Nyquist-stable control system having NDC hereof is absolutely stable and will provide a 20%-40% improvement in performance over existing roll reduction designs when lower performance steering mechanisms are employed, and is superior to linear controllers. That is, the present invention will be effective rudder roll stabilization in commercial vessels having slower rudders as well as in vessels having steering machines representing the best performance currently available, such as military systems. Since no ship hardware modifications are required, the present roll control technology will be able to be economically implemented.
    • 描述了一种具有双反馈路径非线性动态补偿(NDC)的方向舵滚动稳定方法。 具有NDC的高阶奈奎斯特稳定控制系统是绝对稳定的,当采用较低性能的转向机构时,其性能将比现有的轧辊设计提高20%-40%,优于线性控制器。 也就是说,本发明将在具有较慢方向舵的商业船舶以及具有代表当前可获得的最佳性能的转向机(例如军事系统)的船只中有效的舵辊稳定性。 由于不需要对船舶进行硬件修改,因此现有的滚动控制技术将能够在经济上实现。

    • An air conditioning system (10) for a passenger compartment of a motor vehicle having a windscreen comprises a first heat exchanger (14) positionable outside the passenger compartment; a second heat exchanger (18) positionable inside the passenger compartment; an expansion device (16) positioned in a first fluid passage (22) between the heat exchangers; an electronically controlled variable stroke compressor (12) for pumping fluid into the second fluid passage and either in a first direction (X) or in a second direction (Y); reverse flow means (32) in the second fluid passage for controlling the direction of the flow of fluid; first sensing means (36, 40) providing a first output signal indicative of the dewpoint temperature of the air leaving the second heat exchanger; second sensing means (53; 44,46,48) providing a second output signal indicative of the temperature of the windscreen; and control means (26,30) electrically connected to the first and second sensing means and to the compressor for receiving the first and second output signals, for determining the dewpoint temperature for the air leaving the second heat exchanger dependent on the first output signal, for determining the windscreen temperature from the second output signal, for comparing the determined dewpoint temperature to the determined windscreen temperature, and for controlling the stroke of the compressor to maintain the dewpoint temperature at or below the windscreen temperature during fluid flow in the second direction. Reduces the risk of internal fogging of the windscreen.

    • A duplex reproduction system which produces duplex copy sets in collated separated stacks from a stack of precollated documents includes a document feeding apparatus which feeds a stack of documents individually onto the platen of a copy processor for producing copies of each document. The copy sheets are transported to a receiving tray in a sorting apparatus which does not sort the copy sheets when producing the first side of the duplex copies. As an improvement, the copies are cleaned on the back (non-image) sides thereof to remove unfused toner. The documents are reloaded into the document feeding apparatus for feeding the documents with the second side onto the platen of the processor. On the simplex or first pass a circuit disables the sorting function of the sorting apparatus. The copy sheets are removed from a single receiving tray of the sorter for a second or duplex run. On the second pass the copies are cleaned on the first side and distributed sequentially to the different trays of the sorting apparatus which is now energized to produce duplex copy sets in separate collated bundles without rearranging or reshuffling of the documents or copy sheets.
    • 一种双面再现系统,其从一叠预先分色的文件堆叠的分页堆叠中产生双面复印件,包括一个文件馈送装置,其将单个文件堆单独地馈送到复制处理器的台板上,用于产生每个文档的副本。 在制作双面复印件的第一面时,复印纸被输送到分类装置中的接收托盘,该分类装置不对复印纸进行分类。 作为改进,将副本在其背面(非图像)侧清洁,以除去未熔融的调色剂。 文件被重新装载到用于将具有第二侧的文档馈送到处理器的压板上的文件馈送装置中。 在单面或第一遍上,电路禁止分拣装置的分拣功能。 复印单从分拣机的单个接收托盘中移除,进行第二次或双面运行。 在第二次通过时,副本在第一侧被清洁,并且顺序地分配到分拣设备的不同托盘中,该分拣设备现在通电以在单独的对照束中产生双面复印件,而不重新排列或重新安排文件或复印纸。
