摘要： The concentrations of residual heavy metal contaminants in the particulate material in a slurry produced in a particulate material washing process are monitored on-line and can be used to control the washing process. In alternative embodiments of the invention, x-rays, thermal neutrons or laser beams are directed at the slurry as it flows through a flow cell to induce emission of secondary x-rays, gamma rays or light, respectively, characteristic of the heavy metal contaminants and constituents representative of the solids contents of the slurry. These characteristic energies are measured and used to determine the concentration in ppm of the residual heavy metal contaminants in the particulate material within the slurry.

摘要： The zirconium 91 isotope is separated from zirconium by a photo-assisted extraction process wherein a first solution is formed of a first solvent, scavenger and zirconium compound, which compound reacts with the scavenger when exposed to light, and while irradiating the first solution to form a zirconium reaction product, contacting the same with a second solvent that is immiscible with the first solvent and is a preferential solvent for the zirconium reaction product, with the reaction product transferred to the second solution, and the two solutions then separated. An acidic aqueous media is preferred as the first solvent, with excess acid used to provide anions that act as the scavenger.

摘要： An efficient and economical separation of the gadolinium isotopes Gd.sup.155, Gd.sup.156 and/or Gd.sup.157 from mixtures containing the same is effected by a liquid chromatographic column system using an ion exchange resin and an eluant solution. A portion of the eluant solution is used to saturate the columns and a feed solution containing the mixture of gadolinium isotopes is charged to the columns. Further eluant solution is passed through the saturated columns containing the feed solution to form a fraction of eluant solution rich in the desired gadolinium isotopes which is separated from the remainder of the eluant upon discharge from the columns.

摘要： An LED-based color measurement instrument including an illumination system and a sensing system. The illumination system includes modulated LEDs and a temperature control system for regulating the temperature of the LEDs, thereby improving the consistency of their performance. The sensing system includes a photodiode, a transimpedance amplifier, and an integrator in the first stage to cancel the effect of ambient light on the output of the first stage. The sensing system also includes a lens system for imaging a target area of the target sample onto the photo sensor in a manner so that the product of the target area times the solid angle captured by the lens system is generally uniform over a selected range of distances, thereby reducing the positional sensitivity of the instrument with respect to the target sample.

摘要： An instrument and method for measuring light or color using modulated illumination. The system includes an LED illuminator modulated at a specific frequency for illuminating the sample, and a sensor capable of differentiating between the modulated light from the sample and unmodulated ambient light. The instrument is therefore capable of “seeing” only light from the sample, while ignoring ambient light. In a second embodiment, the system includes multiple illuminators of different colors each modulated at a unique frequency so that the sample can be measured at multiple at each of the different frequencies.

摘要： Both a method and apparatus for separating zirconium isotopes by balanced ion migration in a counterflowing electrolyte are disclosed herein. In the method of the invention, zirconium chloride is dissolved in a solution of HCl, and a voltage of between 2 and 50 volts is applied across the electrolyte to create a flow of zirconium ions toward the cathode, and a counterflow of chlorine ions toward the anode which is balanced such that the lighter weight isotopes of zirconium migrate toward the cathode while the heavier weight zirconium isotopes stay in the vicinity of the anode. The apparatus of the invention includes a polarizing assembly formed from a bundle of small diameter glass tubes aligned between the anode and the cathode. The internal shape of the tubes impedes kinetic agitation movement of the zirconium ions in all directions except in the direction between the anode and the cathode, thereby expediting the separation process. Glass frits are used to partition off the electrolyte in the region of both the anode and the cathode so that the isotopes which eventually accumulate in these regions may be drawn off with a minimum of fluid agitation.
摘要翻译：本文公开了通过在逆流电解质中的平衡离子迁移分离锆同位素的方法和装置。在本发明的方法中，将氯化锆溶解在HCl溶液中，并且在电解液之间施加2至50伏的电压以产生朝向阴极的锆离子流，并且将氯离子逆向向阳极平衡，使得较轻的锆的同位素向阴极迁移，而较重的锆同位素停留在阳极附近。本发明的装置包括一个偏振组件，该偏振组件由一排在阳极和阴极之间排列的小直径玻璃管组成。管的内部形状阻止锆离子在除了阳极和阴极之间的方向上的所有方向上的动力学搅拌运动，从而加速了分离过程。使用玻璃料将阳极和阴极区域中的电解质分隔开，使得最终在这些区域中积聚的同位素可以用最少的流体搅动排出。

摘要： The zirconium 91 isotopic content of zirconium is reduced by forming a solution of a zirconium compound and a scavenger of 8-hydroxyquinoline or its derivatives, and irradiating the solution with light at a wavelength which excites the compound so that it reacts with the scavenger. Because the molecules containing the zirconium 91 isotope remain excited longer, they react disproportionately with the scavenger. The reaction product, which precipitates from the solution, is therefore enriched in the zirconium 91 isotope. Micelle-forming agents can be added to the solution to enhance the isotopic enrichment.
摘要翻译：通过形成锆化合物和8-羟基喹啉或其衍生物的清除剂的溶液来还原锆的锆91同位素含量，并用激发化合物的波长的光照射溶液，使其与清除剂反应。由于含有锆91同位素的分子保持激发更长时间，它们与清除剂不成比例地反应。因此，从溶液中析出的反应产物富含锆91同位素。可以将胶束形成剂加入到溶液中以增强同位素富集。

摘要： A color measurement network message log structure is disclosed for use in controlling communications among systems such as a plurality of film processing laboratories and remotely located systems, including a remotely located host system. Each processing laboratory includes at least one film processing apparatus interconnected to a densitometer for obtaining data related to color quality during film processing procedures. Signals representative of color quality data are transmitted from the densitometer to the host system through conventional modem devices and telecommunication lines. The host system can comprise a conventional processor and interconnected printer device. The processor is responsive to signals received from the densitometer at each processing laboratory to process the color quality data represented thereby. Each of the densitometers is provided with a dual port structure for communications with the film processing apparatus and remotely located system. Signals representative of data from the film processing apparatus can be accepted by the densitometer, with the densitometer including a network message structure for queueing the data represented by the signals for purposes of subsequent transmission to the remotely located system. Signals representative of data can be received from the remotely located system and stored internally to the densitometer for purposes of subsequent transmission to a visual display or subsequent transmission to a peripheral device, such as a printer. Still further, the remotely located system is made capable of direct control of the film processing apparatus through the use of a pass-through mode associated with the dual port structure of the densitometer.
