Abstract: The present invention relates to a method for treating plastic bottles comprising an operation for cold plasma sterilization with non-germicidal gasses and/or an operation for the cold plasma deposition of a diffusion barrier layer, said method being characterized in that said cold plasma delivers adjustable nonthermal energy to the entire inside surface of the bottle, said cold plasma being generated either through a distributed propagation of microwaves having a maximum intensity in the vicinity of said surface or by a hollow cathode system adapted to the bottle and supplied with pulsed DC and/or RF voltage. The invention also relates to the devices for implementing the method.

Abstract: Composition (C) comprising per 100% of its mass: from 0.5% to 30% of one or more alcohols of formula (IV): R1—OH??(IV) in which R1 represents an aliphatic radical having from 8 to 36 carbon atoms and from 70% to 99.5% of one or more compounds of formula (I): in which R represents an alkyl radical having from one to eight carbon atoms, n represents an integer greater than or equal to 1 and less than or equal to 10, R1 is as defined previously for formula (IV), at least one of the radicals Z1 or Z2 represents a radical: in which —S— represents the divalent residue of a reducing sugar and p represents a decimal number greater than or equal to 1 and less than or equal to 10 and the other one of the radicals Z1 or Z2 represents a hydrogen atom or said radical.

Abstract: A method for generating a sound giving a sensation of depth by applying, after extraction, a transfer function quadrille onto electric sound signals on the left and right thereof. The transfer functions simulate the trajectories taken by the sound associated with the electric signal to be processed in order to reach two receivers, if this sound was emitted in air. The signals that have been processed, one by one, by one of the four transfer functions of the quadrille, are combined with each other, then the sound signal thus obtained is mixed with the original electric sound signal to be processed after a temporal reset.

Abstract: Method intended for the picking up of sounds coming from at least one sound source, for the recording of said sounds and their play-back, by means of a sound pick-up assembly, a recording medium and a transmission assembly. the sound pick-up assembly being composed of at least two microphones, the relative position of which is constant, the recording medium being of any known stereophonic type, particularly with at least two tracks, the transmission assembly comprising at least two members such as earphones, loudspeakers or speaker boxes. It is characterised in that sounds are picked up simultaneously by the two microphones, known as “right” (11) and “left” (12) respectively and that these two microphones (11 and 12) are displaced together with respect to said sound source (A), particularly by causing the distance and/or height of each microphone (11-12) to vary differentially with respect to that source (A), i.e.

Abstract: The invention aims to optimize a given parameter of a process of coating a support with a liquid composition. The device comprises: a) means (9, 10) for varying the parameter according to a predetermined profile; b) first detection means (11) for producing a first density profile for the support (6) across the width of the support, as the parameter varies; c) second detection means (13) for producing a second density profile for the support (6) parallel to the longitudinal axis, as the parameter varies; and d) means (15, 10) for determining a range of values for the said parameter for which the first and second profiles are satisfactory.

Abstract: A sealed watchcase includes a middle-and-bezel having two concentric annular parts which are held one inside the other by means of friction. The internal part of these two parts is a rigid ring made of ordinary metal or plastic. The external part of these two parts is made of precious-metal and forms a thin casing covering at least the radially external surfaces of the rigid ring. A glass part is bonded inside an internal snap in the precious-metal casing. A back cover is held against a bottom flat surface of the middle-and-bezel by fixing screws which are screwed into the rigid ring and ensure, when tightened, clamping of a fitting ring inserted together with a watch movement into the opening of the rigid ring. Seals are compressed between the back cover and the middle-and-bezel. Only the back cover, the precious-metal casing and the glass form the external parts of the watchcase.

Abstract: Power supplies having power input excitation terminals and power output terminals are tested under differing load and excitation conditions. Excitation sources having differing parameters are selectively connected to the input terminals. A variable impedance load is connected to the output terminals. Voltage measuring apparatus is selectively connected to be responsive to the voltage derived from the selective connecting means and the voltage across the load and is selectively connected to a readout means. A dynamic signal source derives control signals for respectively controlling the parameters of the excitation sources, the impedance of the load, and the connections of the readout means and the measuring apparatus.
