    Abstract: The balancing apparatus is designed for determining with accuracy any want of balance of a test-piece to be imparted with rotation about an axis. This test-piece is fitted on a horizontal turntable rotatable about a vertical axis, so that said axes are coextensive. The turntable is journaled on a non-rotary stand having a stationary bed-plate supporting a board subject to vibrations, through a suspension constituted by two slanting planar resilient systems forming a dihedral which is bisected by said vertical axis and whose edge extends along a horizontal line through the center of gravity of the test-piece. Two displacement sensors detect the vibrations of the board at two selected points thereof so as to sense respectively the linear movements of this board parallel to said horizontal line and its pendular movements about said horizontal line.

    Abstract: A switching device for HF energy which includes, at a distance of lambda /4 from the branching point of one path or circuit into two transmission paths, connections to ground by a switching diode. These diodes may be so biased as to establish communication from the first path to one or other of the two other ones, or to two further transmission paths.

    Abstract: A device for locating at least one edge of a flexible film and designed to present the film in a specific position and in a natural state of tension with no appreciable elongation. The device comprises a plate against which the edge rests, a pair of rollers adapted to grip the film resiliently and to keep it against the plate and stiffening plates 4 and 5 which are curved for the purpose of increasing the moment of inertia of the film in the locating area. The device may be used in the manufacture of balloons of synthetic material made from flexible films.

    Abstract: The processing of an information carried by a frequency with the object of digitizing it is performed along the so-called ''''quasiconstant'''' system used in PFM type telemetric data analysis. Two like but distinct circuits each operating in accordance with the ''''quasi-constant'''' system are used - the recorded information signal and a fresh reference frequency delivered by a clock are respectively applied to the two inputs of one of these circuits, whereas the recorded reference signal and the same fresh reference frequency as above are respectively applied to the two inputs of the other of these circuits.

    Abstract: In order to build up a thin layer coating on a substratum, a target made of a suitable material and located in the vicinity of said substratum is striked under a high vacuum by a beam of ions of high kinetic energy delivered by a duoplasmatron. Several commutable targets may be used for building up multilayer coatings. An intermediate chamber, located at the exit of the duoplasmatron, may be fed with a reacting gas (oxygen, nitrogen, etc.) in order to obtain compound coatings (oxides, nitrides, etc.).
