Patent FR-2650938-A1 (FR)
Title: Electrostatic method for stimulated rain, dispersion of fog, and protection against lightning
IPC: A01G15/00
Filed: 1989-08-17
Abstract: The invention relates to methods modifying the electric charge densities in the upper atmosphere with the aid of balloons, ballasted by a slim conducting cable electrically connected to earth. The upper atmosphere constitutes an importance source of negative charges, of the order of 10<9> coulombs, according to a new theory. It is thus intended to increase the upward speed of the air masses, which may facilitate the triggering of rain and the dispersion of fog. Likewise, a site surrounded with a certain number of balloons kept at heights of the order of 0.1 to 1 km and electrically connected to the ground, is assumed to be protected from lightning, owing to the equalisation of the charge densities on the ground and in the upper atmosphere. The measurement of telluric currents connected with the flow of atmospheric charges in the ground is fundamental for studying these methods. It may constitute a simple means for forecasting the imminence of lightning on a regional scale.

Patent FR-2639361-A1 (FR)
Inventor: HODES ERICH
IPC: B22D19/08
Filed: 1989-11-17
Abstract: Process and device for producing a laminated material for sliding elements with a sliding layer consisting of an alloy in the form of a metallurgical two- or more component system with immiscibility gaps. The sliding layer is continuously cast from the alloy and cooled immediately after casting in a continuous pass at a cooling rate sufficient to prevent the growth of particles of the immiscible metallurgical components to particle sizes greater than 0.01 to 1  mu m, preferably < 1  mu m. To this end, a film can be cast from an alloy and quenched at a high cooling rate. This film is then joined to the substrate which forms the carrier layer, by means of a joining process, preferably using a laser beam. The sliding layer can also be cast from the alloy onto said substrate in one or more steps. Said substrate itself may consist of a strip consisting of a steel backing and an intermediate layer of a bearing metal with good emergency running properties. The following metallurgical two- or more component systems with immiscibility gaps can be cast to form sliding layers: AlPb, AlSn, AlBi, AlSb, CrPb, CrSn, MnPb, FePb, CoPb, NiPb, CuPb and PbZn.

Title: Continuous positive charge capillary columns used in capillary electrophoresis
Inventor: KERR ROBERT
IPC: G01N27/447
Filed: 1991-09-18
Abstract: The inner walls of capillary tubes being fine and of small diameter are provided with a continuous positively charged coating which is used in capillary electrophoresis and is prepared by chemical reaction between the capillary tube inner surface and a bifunctional substance. The first chemical grouping of a bifunctional substance is capable of forming a covalent bond with the capillary tube inner wall surface; the second grouping contains one or more stable, continuous positive charges, possibly in the form of quaternary ammonium. The stable, continuous, positive charge in the capillary tube inner surface coating has a twofold effect: it reverses the direction of the electroosmosis flow while at that same time increasing its value relative to non-treated capillary tubes or to negatively charged or uncharged coatings. The presence of this coating serves to separate several chemical substances at the same time which would not be possible otherwise. It also substantially reduces the adsorption of substances on the capillary tube inner walls using a mecanism different to other types of coatings which improves separation characteristics.
