摘要： In order to provide a shaft coupling between two aligned shafts in which the absolute minimum of torque transferred across the coupling due to misalignment is desired, and to further provide for the capability of mutual axial movement between the two shafts, a unique magnetic coupling is employed. The input shaft terminates in a yoke structure with permanent bar magnets mounted on the yoke facing surfaces. Like poles of the two bar magnets are disposed facing one another. The output shaft terminates in a third bar magnet which is introduced into the space between the other two bar magnets oriented with its north and south poles disposed, respectively, between the facing north poles and the facing south poles of the magnet pair on the yoke. There is thus mutual magnetic repulsion between the centrally disposed bar magnet on the output shaft and each of the bar magnets on the input shaft. Hence, when the input shaft is turned, the output shaft follows trailing slightly in phase by an angle which is a function of the transmitted torque and the strength of the magnets. This coupling, in addition to the characteristics noted above, also has the ability to act as a filter of high frequency angular motion between the two shafts.
摘要翻译：为了在两个对准的轴之间提供轴联接，其中期望由于未对准而传递到联轴器上的绝对最小扭矩，并且进一步提供在两个轴之间的相互轴向运动的能力，使用独特的磁耦合。输入轴终止于磁轭结构，永磁棒磁铁安装在磁轭相对表面上。类似于两个棒状磁体的磁极彼此相对设置。输出轴终止于第三条磁铁，其被引入位于其北极和南极之间的另外两个磁棒之间的空间中，分别设置在磁极对的相对的北极和磁体对的面对的南极之间。因此，输出轴上的中央设置的棒状磁体与输入轴上的每个磁棒之间存在相互的磁力排斥。因此，当输入轴转动时，输出轴跟随着相对的一点角度，该角度是传递转矩和磁体强度的函数。除了上述特征之外，该联接还具有作为两个轴之间的高频角运动的过滤器的能力。

摘要： A work platform for oil drilling, oil production, or other purposes is constructed in arctic waters by locating a natural ice island of suitable area and thickness, and moving it to the desired platform location. The ice island is anchored to the sea floor by installing at least one, but preferably a number of, generally cylindrical sheaths beneath it which extend from the island to the sea floor below. The sheaths are filled with water, and a thermosiphon is installed interiorly of the sheath. As the thermosiphon extracts heat from the water within the sheath, the water is converted to ice, and eventually the entire body of water within the sheath is frozen, thereby forming a column of ice which anchors the island to the sea floor in the desired location.

摘要： The radio frequency resistance between a pair of conductive elements, for example, adjacent pipe sections of a pipeline, which are coupled together through an insulator, may be determined by contacting each pipe section with one of a pair of probes or electrodes connected across the output of a radio frequency oscillator which is coupled to the input of a rectifier and filter circuit. The probes are connected across the oscillator output through a resistor which insures that the direct current output of the rectifier is directly proportional to the RF resistance between the pipe sections. The output of the rectifier is coupled to a meter through an operational amplifier. The meter, which provides a direct readout of the resistance being measured, may be provided with a current limiting circuit which protects the meter from excessive DC current. Calibrating means may be provided to enable adjustment of the gain of the operational amplifier for resistance readings within several ranges.

摘要： A method of and apparatus for the construction of a modular barge is provided wherein individual floatation modules are assembled and secured one to another by the positioning and linking of separable alignment pins therebetween and the threading of tensioning cables therethrough. Each alignment pin has a generally elliptoid shape and an axial cable receiving bore therethrough. Each flotation module is formed with a plurality of sockets complementally shaped for the alignment pins and linked in pairs by transversely extending passages therethrough and spaced along adjacent side walls of the modules to be in registry with one another. With the modules in a spaced array, assembly cables are threaded through certain ones of the module passages. First ends of the cables are anchored to perimeter modules and the opposite ends are tensioned to draw the modules and alignment pins together, wherein the configuration of the alignment pins then facilitates alignment and coupling. A lock provided in each socket and alignment pin secure that coupled relationship. Tensioning cables threaded serially through certain other ones of the module passages and alignment pins provide structural rigidity for the barge through the post tensioning thereof.

摘要： In order to determine the pulse repetition rate of a fluidic oscillator through which a test gas, whose density is to be determined, is flowing, the pressure pulses appearing at one outlet port of the oscillator is sensed with a pressure transducer. The pulses are integrated for a sample period such that, upon transfer or display, the accumulated count directly represents the average pulse repetition frequency during the sample. Means are provided, in a surge tank, for controlling the temperature and pressure of the test gas, and temperature and pressure transducers in communication with the sample fluid in the surge tank are each coupled to voltage-to-frequency converters which drive counters in order that the temperature and pressure of the test gas may also be displayed. An interface to a thermal printer allows the preservation of written records of prf, temperature, and pressure readings. An interface to a digital tape recorder permits magnetic recording of the data for subsequent processing.

摘要： A detector having particular utility in a gas chromotograph uses a sensor to produce signals indicative of parameters of components of a gas. A signal whose level is related to a gas parameter is generated and sent to an amplifier. The output of the amplifier is stored and a signal related to the amplifier output signal is sent by means of a feedback loop to the input of the amplifier to compensate for losses in the amplification and storage processes.

摘要： An ice chipper comprising a pair of cylindrical drums each mounted for counter-rotation about parallel, generally vertical axes. Each drum includes an outwardly rounded, disk shaped bottom surface and an auger flight spiraled helically about the outer cylindrical surface thereof. The auger flights each include a plurality of spaced, outwardly extending teeth to chip the ice abutting the front of the system. The chipper is mounted to the front of a tractor and each drum includes a hydraulic motor which is operated by a hydraulic pump also carried by the tractor. Rotation of the drums causes the auger teeth to chip the ice and tends to pull the drums forwardly while the auger flights carry the ice particles up and out away from the cleared area. Tilting the system forwardly and rearwardly upon the rounded drum bottom surfaces varies the depth of cutting in the vertical direction.
