摘要:
The invention relates to a device for filling at least one receptacle (12) of gel card type initially sealed by a cap. The invention is characterized by the fact that the filling device comprises a piercing member (110) for perforating the cap, means (120) for eliminating the electrostatic charges capable of being borne by the receptacle, and filling means (130) for filling the receptacle after perforation of the cap and elimination of the electrostatic charges.

The invention relates to cleavable surfactants of formula: in which R′ and R, which may be identical or different, represent a hydrogen atom or a linear or branched, saturated or unsaturated alkyl radical, the sum of the carbon atoms of R′ and R being between 5 and 42. The invention also relates to the corresponding derivatives obtained by alkaline hydrolysis or amidation. The invention furthermore relates to the preparation of these surfactants from glucono-1(5)-lactone and a compound of formula R—CO—R′ in the presence of an acid catalyst, R and R′ having the meaning given above. The surfactants are used in particular in emulsion polymerization and in the field of cosmetics.

The present invention relates to an image processing method intended for correcting the distortions created by the instability of the high-voltage supply circuit in a cathode-ray tube display device. The corrections are made to the video content of the images to be displayed. They consist in characterizing the image distortions created by the high-voltage supply circuit of the cathode-ray tube, then in determining, for each of the images to be displayed, the distortions affecting them, and finally in generating precorrected images having the reverse distortions. According to the invention, to characterize the distortions created by the high-voltage supply circuit, a model capable of delivering, as a function of the video signal of the images to be displayed, a signal representative of the variations in the output voltage of the high-voltage supply circuit while these images are being displayed.

The invention relates to a multiwinding coil intended to serve as a deflection coil for a cathode ray tube. It is provided that on and/or between the winding wires an element made of polymeric material or a mixture of polymers situated within a delimited area of the coil. This enables “ringing” phenomena to be reduced.

The invention relates to a method of processing video images which is intended to correct the distortions created by the instability of the high voltage circuit of the cathode ray tube display device during the displaying of the images. It is more particularly intended for correcting the global zoom and the local zoom affecting the images displayed by the cathode ray tube device.
