    摘要: A mandrel for holding gradient coils in an instrument that measures nuclear magnetic resonance is fastened directly to the magnet of this instrument. It is shown that this arrangement can be used to reduce the output of noise while, at the same time, making it easy to adjust the position of the mandrel. The device comprises two sets of brackets fastened by their struts, on either side of the magnet, to the end rings of the magnet. Each bracket exerts a holding force on the mandrel.

    摘要: A gradient coil is provided for a nuclear magnetic resonance image forming apparatus, the gradient coil being formed of four identical arrangements symmetrical with respect to the centre of a predetermined examination space. These arrangements comprise conductors formed in the shape of a saddle. In a particular embodiment for each arrangement two groups of conductors are provided. They may moreover be superimposed. In the invention, the conductors are flat conductors. Preferably their section is rectangular, the large side being greater than or equal to two and a half times the small side. The choice of flat conductors reduces the self-inductance of the system thus constructed. Finally, it is the necessary driving power which is reduced for establishing a field gradient. The temperature behavior of the whole of the apparatus is improved thereby.

    摘要: A reactor for aerobically or non-aerobically treating a fluid flowing from the bottom to the top of the reactor through a fluidized bed of granular material. The reactor includes a base having an orifice therein, through which fluid flows into the reactor and in which gas is added to the fluid. A horizontally extending plate surrounded by a supple membrane faces the base and the orifice. The plate and the membrane form a valve for preventing fluid from the reactor from entering the orifice in the event fluid flow into the reactor ceases. The gas entrains the granular material so that when the gasified fluid passes upward through the granular material a three-phase liquid-gas-granular material mixture is produced. The upper portion of the reactor includes a device for disembedding the granular material from the fluid, a device for degasing the three-phase liquid-gas-granular material mixture, and a device for separating the granular material from the fluid to produce a fluid discharge. The separation device also recycles the granular material into a fluidization zone. Also provided is a device for recycling and recuperating the fluid discharge into the fluidization zone of the reactor, thereby fluidizing the bed of granular material.

    摘要: The invention provides a device for creating an excitation field in an apparatus using nuclear magnetic resonance. The structure for creating this field comprises a number of conductors spaced evenly apart at the periphery of a circular cylinder. What characterizes the invention is that, for producing a homogeneous field inside this cylinder, it is sufficient to cause a current to flow through these conductors whose intensity is proportional to the cosine of the angle which locates this conductor with respect to a reference axis system.
