    摘要： An arrangement enables the frequency variation of a resonant element (an accelerating section for example) to be followed in dependence upon its temperature and the frequency of the hyperfrequency generator G feeding this resonant element Q to be controlled in dependence upon the frequency variations thereof. The arrangement comprises at least one reference cavity C associated with means for allowing the circulation of cooling fluid along the walls of said reference cavity and with heat supply for bringing it, at any instant, to the temperature of the resonant element Q, means for measuring the amplitude variation .DELTA.a of the signal corresponding to the frequency variation of said reference cavity C in terms of its temperature variation and a frequency variation system controlled by a signal proportional to the amplitude variation .DELTA.a, for modifying the operating frequency of the generator G. This arrangement makes it possible to improve the performance of medical accelerators of which the thermal time constant is considerable in relation to their short operating time.

    摘要： The invention relates to a .gamma.-ray irradiation head for panoramic irradiation comprising a tungsten target revolving about an axis, and means for deflecting electrons around the same axis for producing photons in several directions either successively or simultaneously. When the beam of electrons is deflected in its entirety and when the impact zone moves on the target about the axis, the axis of the radiation lobe moves in the same way and permits irradiation according to a variable azimuth.

    摘要： A device for fastening a flexible tie has a hollow body provided with a guiding channel that forms a funnel for a translationally movable blocking element, this blocking element being subject to the constant action of an elastic element. The hollow body is housed in a case where it can move translationally parallel to the blocking element, and the blocking element is maintained in the case, on one side by virtue of the elastic element that acts directly between the blocking element and the case, and on other side by virtue of an abutment. A retractable abutment makes it possible to retain the hollow body against the blocking element to block the tie, or to release this hollow body so as to enable the sliding of the tie. The fastening device is particularly adapted to ensure the adjustment of a garment or a shoe by means of a tie, such as a lace.

    摘要： A hyperthermia apparatus primarily applicable to the treatment of tumors comprises at least three high-frequency generators connected to three electrodes. The electrodes are intended to be coupled to a patient's body which constitutes the load, thus producing a higher temperature rise in the vicinity of a fictitious electrode in the body. The generators have adjustable phases and amplitudes, the output of each generator being connected to each of the three electrodes.

    摘要： A beam of charged particles is guided along a path including a looped section between two rectilinear stretches, each of these stretches being provided with focusing and centering means. A holder insertable into the outgoing stretch, ahead of a collimator, carries a target designed to emit photons upon being struck by incident particles. The target holder is linked with a retracting mechanism which also controls a diaphragm in the looped path section to narrow its aperture when the target is in place. A dose-equalizing filter utilized in the latter instance is movable jointly with the target holder out of the path of the exiting beam.
