摘要： The subject of the present invention is an electrical commutator having slip rings and its method of manufacture. It consists of two insulating pieces (6) and (7) surrounding two conductors (3) and (4) associated with the rings (1) and (2) which, by friction, provide electrical continuity between a fixed piece and a rotating piece (which carries the commutator). This commutator is noteworthy in that it is the rings, crimped by electromagnetic forming, which ensure retention of all the component pieces of said commutator.

摘要： A method and mass for the drainage, irrigation and lightening of soils is constituted by hollow elements dispersed in soil so as to define capillary or semi-capillary passages. The elements are bulked up so that they can rest in an irregular fashion one relative to the others by providing in between them spaces of variable shapes and dimensions thereby to supply drainage, irrigation, lightening and enrichment of soils.

摘要： A ring laser for penetrating electromagnetic radiation such as X or gamma rays, using a pumping beam supplied by a primary lightwave or infrared laser. A member made of active material is illuminated by the beam, which has symmetry of revolution around its axis and whose electric lines of force are circles centered on the said axis. The pumping beam is conveyed by a mirror toward the end of a circular metal channel having a semi-toroidal cross-section and containing the active member, the mirror being formed with an aperture near the axis and transmitting the X or gamma rays emitted by the active member after they have been propagated along the end of the channel. The active member may be made of a substance which can undergo thermonuclear fusion by absorbing X or gamma rays. The active substance may also be a boron hydride or a boronate.

摘要： 425,803. Electromedical apparatus for producing artificial fever. LEROY, R. P. E., 1, Rue Cabanis, Paris. May 22, 1934, No. 16293. Convention date, May 23, 1933. [Class 81 (ii)] In apparatus for producing artificial fever comprising a high-frequency circuit with electrodes not in contact with the body to be treated, the electrodes are so disposed that their mutual capacity is quite small compared with the capacity between each of them and the body. Figs. 3 and 5 show typical arrangements. By making one electrode 3, Fig. 5, of small size an intense local heating of one region 5 of the body may be effected together with a general heating of lower intensity. Wave-lengths of 12-25 metres are mentioned. The Specification as open to inspection under Sect. 91 comprises also the separation of the application circuit B, Fig. 6 (Cancelled), from the generating circuit A, the energy being transferred by induction between the coils 1, 2, optionally with the interposition of an intermediate circuit. Several application circuits can thus be operated by a single generating circuit. This subject-matter does not appear in the Specification as accepted.
