Abstract: The invention relates to a high-speed bidirectional analogue switch which is controlled by logic signals. The switch proposed has a control circuit (CDD) consisting mainly of an oscillator (OSC) which supplies charging pulses to one end (en1) of a primary winding of a first transformer (TR1) via a first logic circuit (pt1) driven by control signals supplied on one control input (EC) of the switch, and to one end (en2) of a primary winding of a second transformer (TR2) via a second logic circuit (pt2) driven by the said control signals originating from the said control input (EC) by way of a logic inverter (in1), and a controlled circuit consisting especially of a first (TM1) and of a second (TM2) MOS-type transistor, the gate electrode (dg1, dg2) of which is connected respectively to one end of a secondary winding of the said first transformer (TR1) and to one end of a secondary winding of the said second transformer (TR2) via diodes (rd1 and rd2). The invention is applicable in signal transmission systems and telephone installations, for example.

IPC: H01S3/04
Filed: 1992-03-11
Abstract: Oscillateur laser 20 pompé par l'extrémité comportant un amplificateur comprenant un milieu amplificateur 32 à l'état solide. Des faisceaux de pompage 44, qui sont produits par deux groupes de barrettes 40 de diodes-lasers placés entre les éléments optiques définissant le résonateur optique, sont dirigés sur deux surfaces d'extrémité opposées 34, 36 du milieu amplificateur à l'état solide, qui coupent l'axe optique 28 du résonateur optique. Les barrettes de diodes-lasers de chaque groupe sont distribuées circonférentiellement autour de l'axe optique suivant une configuration uniforme et à la même distance le long de l'axe optique à partir du milieu amplificateur. Un groupe de barrette de diodes est disposé d'un côté du milieu amplificateur et l'autre groupe est disposé de l'autre côté du milieu amplificateur. L'énergie du faisceau de pompage est ainsi dirigée effectivement et efficacement sur les deux surfaces d'extrémité du milieu amplificateur à l'état solide à partir de plusieurs barrettes de diodes-lasers, ce qui permet à la puissance de sortie produite par le milieu amplificateur d'être augmentée jusqu'aux limites thermiques du milieu amplificateur.

Title: Dosing of chlorine tablets into domestic swimming pools
Inventor: HERVE MOSNY
IPC: C02F1/68
Filed: 1993-12-22
Abstract: Chlorine is dosed into a swimming pool by progressively dissolving tablets of chlorine held in a ''skimmer'' at the surface, through which water circulates. The skimmer is made of a hollow tubular reservoir (7) which contains chlorine tablets which can fall freely inside the tube. It passes vertically through an opening (8) in a horizontal support plate (9). The top of the tube is closed by a removable cover (10). The base and lower sides of the tube have openings (11) through which water can pass. The depth of immersion of the skimmer can be adjusted by raising or lowering it, relative to the support plate. A ring (18) between the outer wall of the tube and the top of the plate holds the skimmer in the position chosen. This regulates the flow of water through the skimmer.

Title: Heater casing surface intrinsically safe to touch
Inventor: MENET JACQUES
IPC: F24C7/04
Filed: 1994-07-11
Abstract: In a typical heater, a heat-emitting panel (3), of e.g. fibre-reinforced polyester, carries a resistive circuit (1), under an insulating backing plate (2), on one side. On the other, exposed, side, the material presents a relief pattern, comprising an array of spikes or rods (4), preventing access to the main body. Contact can occur only on the extreme tips of the spikes, etc., and the area touched cannot exceed 50 percent of that obtained in similar contact on a plane surface. The protection provided depends on the material, the spike height (9) and the effective contact area reduction. Prototype tests show safe operating temperatures as high as 120 deg. C. are feasible.

Title: Facilitating purificn., counting and activation measurement on leucocytes
IPC: G01N33/49
Filed: 1995-03-02
Abstract: Process for facilitating purificn., counting and measurement of activation of blood leucocytes comprises (1) collecting the blood in an EDTA-heparin mixt.; (2) allowing the cells to settle spontaneously under gravity in tubes inclined at about 30  deg C, then (3) aspirating the cell-rich plasma as sedimentation of the red cells progresses.
