摘要： An oxygen generator includes a monolithic body having first and second channels extending longitudinally therein. An electrode is operatively disposed in the first channels and a counter-electrode is operatively disposed in the second channels. The second channels are formed in the monolithic body so each second channel is electrically isolated from, yet adjacent to a first channel, resulting in an alternating configuration of first and second channels. The first channels have fluid or oxygen flowing therethrough, while the second channels have the other of oxygen or fluid flowing therethrough. An output manifold, having an oxygen collection area separated from a fluid collection area, operatively engages with the monolithic body. The oxygen collection area receives substantially pure oxygen from one of the second or first channels, and the fluid collection area receives oxygen-depleted fluid from the other of the first or second channels.

摘要： A non-thermal plasma reactor is provided. The reactor includes a plasma-generating substrate, a housing, a voltage supplied to the plasma-generating substrate, and a retention material. The plasma-generating substrate has one or more flow paths for an exhaust gas. The plasma-generating substrate includes at least one weak area and at least one strong area. The housing has an inlet opening and an outlet opening. The voltage is supplied to the plasma-generating substrate for generating a plasma field. The retention material retains the plasma-generating substrate in the housing such that the one or more flow paths are in fluid communication with the inlet opening and the outlet opening. The retention material is configured to provide a higher retention force to the at least one strong area and a lower retention force to the at least one weak area.

摘要： A vehicle such as a combine harvester or the like includes a main frame and a first and second undercarriages for supporting the main frame and individually having front and rear wheel assemblies and a track encircling the wheel assemblies. A suspension structure therefore includes a laterally spaced apart pair of pivot joints adjacent the front wheel assemblies for pivotally connecting the undercarriages to the main frame, and a coupling assembly adjacent the rear wheel assemblies for centrally supporting the main frame on the undercarriages. A hydraulic motor powerably rotates each of the rear wheel assemblies and an inside support device is provided therefor that includes a stabilizing beam. The coupling assembly includes an equalizer bar having outer ends, and the stabilizing beam extends rearwardly beyond the driven rear wheel assemblies for connection to the outer ends. Also, an outside support device releasably clamps the rear wheel assemblies to the undercarriages.

摘要： Movable sensing arrangements are prone to damage, unable to position a load engaging device relative to a load for stacking purposes, and unable to controllably position the sensing arrangement. A movable sensing apparatus having a housing and first and second signaling devices mounted in the housing is provided. A guide rail assembly elevationally movably mounts the housing on a carriage assembly and an actuator controllably elevationally moves the housing along the guide rail assembly. A coupling connects the actuator to the housing and releases the housing from connection with the actuator in response to a force of a preselected magnitude being applied to the housing. Thus, the problems related to damage, stacking, and positioning are reduced. The movable sensing apparatus is particularly suited for use on an automatic guided unmanned vehicle having a lift mast assembly.

摘要： An array of optical waveguide transducers, especially suitable for use in a multi-channel hydrophone seismic streamer, contains optical waveguides which are deformed in response to the parameter being sensed (underwater acoustic energy in the case of the seismic streamer). Two optical signals are obtained from each transducer, amplitude modulated in opposite polarity in accordance with the parameter and returned to a collection point by way of optical signal highways, such as optical fiber waveguides. The optical signals are time division multiplexed on the return highways by successively providing light pulses to each of the transducers upon activation of separate light sources associated therewith which are electrically activated by electrical signals propagated along a transmission line wherein the electrical signals are successively delayed. The optical signals on the return waveguides appear in time slots corresponding to the successive delays and may be sequentially interrogated at a rate compatible with the frequency response of the array system. At the collection point, the outputs of the return waveguides are subtracted thereby summing the optical signals from each transducer, while reducing noise introduced into the system as may be due both to variations in the amplitude of the light from the sources and mechanically due to deformation or bending of the optical waveguides other than in response to the parameter being sensed.
摘要翻译：特别适用于多通道水听器地震拖缆的光波导换能器阵列包含响应于被检测参数而变形的光波导（在地震拖缆的情况下为水下声能）。从每个换能器获得两个光信号，根据参数以相反的极性进行幅度调制，并通过诸如光纤波导的光信号高速公路返回到采集点。光信号在返回高速公路上进行时分复用，通过在激活与其相关联的分离光源时连续地向每个换能器提供光脉冲，其通过沿着传输线传播的电信号被电激活，其中电信号被连续延迟。返回波导上的光信号出现在对应于连续延迟的时隙中，并且可以以与阵列系统的频率响应兼容的速率顺序询问。在收集点，减去返回波导的输出，从而对来自每个换能器的光信号进行求和，同时降低引入到系统中的噪声，这可能是由于来自光源的光的振幅的变化以及机械地由于变形引起的或弯曲的光波导，而不是响应于被感测的参数。
