摘要： A process and a centrifuge are provided for separating a gas mixture having different molecular weights into a light fraction and a heavy fraction. The process comprises the steps of introducing the gas mixture into at least one intermediate space formed between at least two concentric rotors, and separating the gas mixture into a light fraction and a heavy fraction by subjecting the gas mixture to centrifugal forces by rotation of the concentric motors. The centrifuge comprises at least two concentric rotors rotatably in a housing and defining between them one or more intermediate spaces, means for driving the rotors, and means for introducing the gas mixture into the or each intermediate space, whereby in operation the mixture is subjected to centrifugal forces.

摘要： A laser beam for ultrasonic generation is emitted to a reflector/vibrator to generate an ultrasonic wave, and the ultrasonic wave is transmitted to an object to be inspected. The ultrasonic wave transmitted to the object is reflected at a flaw inside the object, returns to the reflector/vibrator and vibrates it. The vibration is detected using a laser beam for ultrasonic detection to find flaws inside the object. According to the present invention, ultrasonic flaw detection can be made for reflecting materials having corrugations on their surface or having a low reflection factor of light, and for objects made of materials which cannot easily generate the ultrasonic wave by the laser beam. For such materials, the conventional method has not been useful because it adopts the direct application of the laser beam to the surface of the object to generate the ultrasonic wave.
摘要翻译：将用于超声波产生的激光束发射到反射器/振动器以产生超声波，并且将超声波传输到待检查对象。传递到物体的超声波在物体内部的缺陷处被反射，返回到反射器/振动器并使其振动。使用用于超声波检测的激光束检测振动，以发现物体内的缺陷。根据本发明，可以对其表面具有波纹或具有低的反射系数的反射材料以及由不能通过激光束容易地产生超声波的材料制成的物体进行超声波探伤。对于这种材料，常规的方法并不有用，因为它采用将激光束直接施加到物体的表面以产生超声波。

摘要： A structure of a mounting portion for a replaceable component such as a filter, a glove, a bag or the like, which mounting portion is attached to the wall (2) of a shield box accommodating internally a substance or a device which must not make direct contact with the hands, such as radioactive or other harmful substance. The mounting portion incorporates a cylindrical stationary port (21) fixedly secured to a wall (2), and a cylindrical replacing port (25) detachably inserted into the stationary port (21) and having a replaceable component therein. Since a plurality of rings (27) made of rubber or a rubber-like elastic material are disposed axially in space and deformed under compression between the inner peripheral surface of the pod (21) and the outer peripheral surface of the port (25) to seal the gap therebetween, the replaceable component may be replaced by pushing out the used replacing port with another.

摘要： A gas centrifuge unit for assembly into a system for separation and enrichment of mixtures of gases according to minute differences between mass numbers of isotopes, each unit having an elongated rotor rotating at a high velocity within an outer cylinder, holes in each end of the rotor for the jetting of respectively enriched gas and depleted gas, calculated to establish a ratio of 1:1 of enriched uranium 235, containing gas mixture, to be jetted out of the upper holes to an upper chamber to depleted uranium 235 gas mixture jetted through the lower holes to the lower chamber, means to heat the upper rotor region and to cool the lower rotor region, an upper and a lower container and a circumferential chamber between them formed by the walls of the centrifuge housing and the rotor within it; orifices and means to supply a gas mixture into the rotor, and to withdraw gas mixture from the central region of the rotor, conduit means in the upper and the lower ends of the rotor to duct gas mixtures from the upper and lower regions of the rotor in the adjacent upper and lower containers, respectively, an orifice in the circumferential chamber to duct thereto gas withdrawn from the lower region of the rotor, orifices in the upper and lower chambers to withdraw therefrom, respectively, the gases collected there, and conduit means connecting each centrifuge unit with a successive centrifuge unit with means to controllably withdraw the enriched gases. A process for the separation and enrichment of uranium 235 comprising steps analogous to the above described means, whereby mixed uranium gas 235 is mixed with helium under high speed centrifugal force, simultaneously cooled at one end and heated at the other, thus aiding in its separation into different regions of gases of different mixtures and different mass numbers of isotopes and recycling some of the gases controllably into the system in a cascade of steps, by returning the depleted uranium 235 gas with the inner light gas back to the rotor and by feeding the enriched gas of uranium 235 with inert light gas to the rotor of the subsequent centrifuge.

摘要： A method of melting treatment of radioactive miscellaneous solid wastes wherein, even when the wastes contain various kinds of substances in a mixed state, each of the substances is efficiently induction-heated and the whole of the wastes can be melted quickly. The radioactive miscellaneous solid wastes (15) are charged into a water-cooling type cold crucible induction melting furnace (10) disposed within a high-frequency coil (12). A plurality of high-frequency currents each having a frequency suitable for induction-heating each of the various kinds of substances contained in the radioactive miscellaneous solid wastes are supplied to the high frequency coil (12) to melt the solid wastes by being induction-heated. The high-frequency currents of different frequencies may be simultaneously supplied to a single high-frequency coil (12) or may be supplied to a plurality of high-frequency coils, respectively.
