Abstract: A double spectrograph system is disclosed. An entrance slit receives and passes light to be analyzed. A first focusing diffraction grating receives that light. A second focusing diffraction grating receives light reflected by the first focusing diffraction grating. The first and second focusing diffraction gratings both have the characteristic of forming planar substantially anastigmatic spectra. Mounting means keeps the first and second gratings at positions symmetrical about an imaginary plane and with their respective focal planes substantially coincident with each other and the imaginary plane. An exit slit receives the light after it has been reflected by the first grating to the second grating and from the second grating to the exit slit.

Abstract: A method of making a corrected plane holographic grating within one band of wavelengths, intended for use in a diffraction apparatus in which light emitted by an entry source (1) is collimated by a spherical mirror (2) to the grating (4), which reflects parallel pencils to another spherical mirror (7), a focusing mirror, is disclosed. An auxiliary holographic grating (25) is created by the interference on a spherical surface (15) of a parallel pencil of light produced by the spherical mirror (7) subsequent to reflection onto a plane mirror (12) and of a divergent pencil deriving from the center of the surface (15). The auxiliary grating, corrected by the interference on a plane surface (22) of a parallel pencil produced by the spherical mirror (2) and of another parallel pencil produced by the auxiliary grating (25) illuminated from the center of the spherical surface, is then recorded.

The device makes it possible to analyze the polychromatic light coming from an excitation source and comprises a polychromator provided with a concave grating, which receives the said polychromatic light through an inlet slit in order to diffract it into monochromatic bundles of the ultraviolet region, directed onto outlet slits that are associated with measuring detectors, the slits and grating being positioned on the Rowland circle, wherein, essentially, the order O bundle, which is symmetrical to the incident bundle, relative to the perpendicular on the grating (23), is taken up by a second optical device which disperses the said bundle into monochromatic bundles of the visible or near infra-red regions, at least one outlet slit (8) selecting one monochromatic bundle, measured by a measuring detector (28). The device is particularly intended for a direct reading emission spectrometry instrument.

Abstract: The invention concerns a device for adjusting angular play on a predetermined angular range of an optical element mobile in rotation relative to a frame. Said device comprises a contact piece (3), integral with the optical element, and an elastic steady arm (4). The steady arm has a first end (41) fixed to the frame and a second end (42) co-operating with the contact piece when the mobile element is oriented in the predetermined angular range, at least when the mobile element enters said angular range in the rotational direction (S1), such that the steady arm exerts on the mobile element a counter-torque. Said second end does not co-operate with the contact piece when the mobile element is oriented outside the angular range.

Abstract: A system for powering a multicurrent locomotive having 2N motors where N is greater than or equal to 2, the system comprising 2N pairs of voltage converters respectively associated with the 2N motors, each motor M.sub.i being powered by means of an inverter connected to the terminals of a parallel capacitor. When the locomotive is powered with AC, then each of the pairs forms a 4-quadrant converter in which the two portions are implemented by the secondary winding of a transformer whose primary winding is connected directly to the terminals of the AC power supply. When the locomotive is powered with DC, the switches serve to use the voltage converters either as voltage-lowering choppers or as voltage-raising choppers. The power supply system is designed in such a manner that in the event of a converter or an inverter failing, it suffices to isolate the failed element to conserve the functions that remain. Availability is thus considerably improved since even in the event of a failure, tractive effort is conserved from at least three motors.
