Abstract: A device for placing disks contained in a cartridge comprises a disk cartridge receiving area, a piston, means for moving the piston between a high position and a low position to enable, in the state in which a disk is positioned in the path followed by the piston during the transition from the high position to the low position of the piston, the disk to be placed on a surface vertically in line with the disk, a transfer system capable of transferring a disk from the cartridge in the cartridge receiving area to a location, arranged in the path to be followed by said piston, the said transit area. The device comprises a disk motion assist guide positionable in the transit area and moveable in a direction parallel to the up and down direction of movement of the piston.

Abstract: A device and method for observing an object, in particular a biological object includes a light source able to illuminate a sample. Under the effect of the illumination, the object emits back-scattered radiation that propagates to a screen, the area of which is larger than 100 cm2. The projection of the back-scattered radiation onto the screen forms an image representative of the back-scattered radiation, called a scattergram. An image sensor allows an image representative of the scattergram formed on the screen to be acquired.

Abstract: A device and method for observing an object, in particular a biological object, includes a light source able to illuminate a sample, and a screen lying between the light source and the object. The screen includes an aperture, through which propagates the illuminating beam produced by the light source and propagating toward the screen. Under the effect of the illumination, the object emits back-scattered radiation that propagates to the screen, the area of which is preferably larger than 100 cm2. The projection of the back-scattered radiation onto the screen forms an image representative of the back-scattered radiation, called a scattergram. An image sensor allows an image representative of the scattergram formed on the screen to be acquired.

Abstract: A device for mounting a dividing wall for separating the main air stream and the bypass air in a bypass turbojet engine afterburner is disclosed. The device includes an attachment unit which attaches the upstream end of the wall to a guide vane casing and a supporting unit which supports the downstream end of the wall provided on flame holder arms of the afterburner radially on the inside of the dividing wall.

Abstract: An electron gun includes a sealed chamber under vacuum. A cathode having an emitting face is placed inside the chamber. An anode forms a sealed window, formed facing the emitting face in one of the walls of the chamber. The anode is capable of allowing electrons emitted by the emitting face to pass through. A biasing apparatus sets up a voltage between the anode and the cathode, capable of accelerating these electrons towards the anode, the electrons thus accelerated forming a beam that passes through the anode. The anode and the emitting face each have a curvature, the curvature of the anode making it capable of resisting a pressure difference between the inside and the outside of the chamber and being designed to cooperate with the curvature of the emitting face to focus the electron beam outside the chamber.

Abstract: The turbojet of the invention includes a combustion chamber, a channel for heating the gas stream, where the heating channel includes at least one device for injection of fuel into the gas stream, which includes an open chamber, with a U-shaped section, having at least one wall within which extend fuel-injection means, which inject the fuel in at least one direction. It is characterised by the fact that a cooling jacket is provided in the chamber, alongside the wall forming the base of its U-section, and the fuel injection device includes protection means interposed between the fuel-injection means and the wall, in a fuel-injection direction. Thus, as a result of the invention, the fuel injection device, which is bathed in a very hot environment, is protected against thermal shocks due to the projection of colder fuel onto its walls, and its life expectancy is therefore increased.
