Patent WO-9114345-A2 (WO)
Title: Television set with separate processing of luminance signals and chrominance signals
Inventor: KAADEN JUERGEN
IPC: H04N9/77
Filed: 1991-03-02
Abstract: The luminance signal (Y) generally has a greater bandwidth and therefore a shorter transit time than the chrominance signal. To compensate this difference in transit time, a retardation stage must be provided in the path of the chrominance signal (Y). For a luminance signal of high bandwidth, this is a relatively complex and costly component. The aim is to simplify this harmonization of the transit times of luminance signal and chrominance signal. To equalize the transit times, instead of the luminance signal being retarded, the chrominance signals are read at higher speed from memories (M2, M3) during a time interval which is not visible in the picture. The present invention is particularly suitable for image storage devices for HDTV sets with high picture frequency and/or line frequency.

Title: Method and device for determining the threshold of heavy fraction deposit contained in a liquid hydrocarbon fluid
Inventor: ZHOU HONGGANG
IPC: G01N33/28
Filed: 2000-11-08
Abstract: The invention concerns a method whereby a fluid sample is brought (1) at constant pressure Pe and temperature maintaining the heavy fractions, in particular asphaltenes, in dissolved state and/or in stable colloidal state, at the intake (4) of a capillary passage with high pressure drop. Said sample is forced to flow through the capillary conduit, at an increasing flow rate. The method consists in measuring (11) the fluid pressure Ps and the fluid flow rate D (12) at the outlet (5) of the capillary conduit and in representing the variation curve of the quantity ΔP = Pe - Ps or the quantity D as a function of the other quantity or as a function of time. The deposit pressure, characteristic of the threshold of deposit of heavy fractions, is defined as the value of pressure Ps, which corresponds to a change of the slope in the variation curve of the quantity ΔP or the quantity D.

Title: Leaching sulphide ore to dissolve lead - which is pptd. as lead chloride and reduced by hydrogen to obtain high purity lead (SW 7.11.77)
Inventor: LAMBERT BERNARD
IPC: C22B13/00
Filed: 1976-09-24
Abstract: The parent patent described the leaching of a sulphide ore or concentrate, contg. Pb and other metals, with an aq. soln. contg. the chloride(s) of Cu, Bi and/or Ag, using below the stoichiometric amt. of chloride needed for complete soln. of the Pb. In this addn. the Pb in soln. is recovered as PbCl2 crystals, which are then melted and reduced by H2. Redn. is pref. at 750-850 degrees C., esp. using H2 diluted by an inert gas and injected into the molten PbCl2. The hourly flow of H2 is pref. at least twice the stoichiometric amt. necessary for total redn. of the PbCl2; and the H2 in the gases leaving the redn. process is pref. sepd. from the HCl obtd. and recycled to the redn. process, whereas the HCl is recycled for dissolving the lead. Metallic lead with high purity can be obtd.; the Cl ions are directly recovered as HCl which is recycled; and the reducing agent is inexpensive. The process also eliminates extra processing stages which were necessary with the earlier patents.

Title: Manual clamping tool
IPC: B25G1/06
Filed: 1985-03-14
Abstract: The invention relates to a clamping tool whose handle 2 is articulated to the rod 1 so as to be able to occupy two positions perpendicular to one another. In each of these two positions, the rod can slide axially in the handle so as to engage in locking housings 8. In order to hold the rod in position and prevent it from sliding under the effect of its own weight, the articulation encloses a spring 24 which is pressed by a bush 28 fixed in the handle, so as to bring about friction of the rod against the handle. Furthermore, the rod comprises lateral protuberances engaging in grooves at the end of the handle. The invention may apply especially to a screwdriver or a box spanner.

Title: Solid fuel burning with a blue flame, liquid fuel burning with a blue flame, fuel for diluting in order that it should burn with a blue flame
Inventor: BENOIT BALLAND
IPC: C10L1/12
Filed: 1990-02-02
Abstract: A solid fuel and a liquid fuel burning with a flame of a blue which is more or less maintained as a function of the percentage of cupric chloride CuCl2.2H2O and of the percentage of dichloroethane, relative to the proportions of alcohols in the case of liquids and of solid fuels of the hexamethylenetetramine, metaldehyde and similar type, in the case of solid fuels. In the case of the latter soaking the cupric chloride in the dichloroethane and then drying by evaporation of the halogenated hydrocarbon (dichloroethane) suffices to modify the composition of cupric chloride in order that when agglomerated with a solid fuel, or else diluted in solution in a liquid fuel in which it can dissolve, it subsequently burns with a blue flame. The density of the blue depending entirely on the concentration of CuCl2.2H2O in the composition.

Abstract: Selon l'invention, le signal d'entrée (110) vers un amplificateur (112) non linéaire subit une distorsion préalable par injection au coupleur (124) d'un signal correcteur. Pour produire le signal correcteur, on amplifie un échantillon du signal d'entrée au moyen d'un amplificateur (130) qui présente sensiblement les mêmes caractéristiques de production de distorsion que l'amplificateur (112). La sortie de l'amplificateur (130) est échantillonnée, et la principale tonalité d'énergie est éliminé au niveau du coupleur directif (138), le signal correcteur étant laissé pour injection vers le trajet principal des signaux. La partie principale de la sortie de l'amplificateur (130) est ajoutée de façon cohérente à la sortie de l'amplificateur (112) afin d'améliorer l'efficacité. Le signal correcteur peut être traité de façon à corriger la distorsion au niveau de la sortie du mélangeur (152) due à la partie principale de la sortie de l'amplificateur (130).
