Patent EP-0288988-A1 (EP)
Inventor: BERNARD JEAN-JACQUES
IPC: H01Q3/26
Filed: 1988-04-27
Abstract: The antenna includes at least one group of antenna elements (EA1, EA2, . . . , EAp). Microwaves emitted by a central emitter (EH) reach a particular element (EA1 for example) by passing through a controllable phase shifter (VE1), a laser (LE1) which modulates a carrier light signal at a frequency specific to said antenna element with the microwaves, via an optical deflector (FIE) which injects said light signal into an optical waveguide (GE) which is common to all of the antenna elements in the group, via an optical deflector (FPE) which directs said light signal to a detector which is specific to said antenna element (EA1), and which reconstitutes the microwaves, and via a microwave amplifier (AE1) which applies the microwaves to said antenna element. The system is applicable to telecommunications and to radar.

Abstract: A method for the cosmetic treatment of human skin, particularly facial skin, for the removal of materials from the surface and the sebaceous follicles is dis­closed. The method comprises applying a layer of liquid polymerizable adhesive to the skin, then applying a pliable adhesive tape to cover the applied liquid adhe­sive and allowing the polymerization of said layer of polymerizable adhesive to take place and then removing the layer of polymerized adhesive from the skin by stripping the tape from the skin. In this treatment the materials on the surface of the skin and within the sebaceous follicles being attached to and removed with the layer of polymerized adhesive along with the tape. Alpha-cyanoacrylate is usefully employed as the poly­merizable adhesive in this treatment.

Abstract: Apparatus for extracting variable doses, intended for equipping machines for preparing beverages from powdered or granular raw material, such as espresso coffee machines, of which current models suffer from being able to process only a fixed dose of ground coffee. The distribution of the powder in current extracting vessels is not generally homogeneous, which has an adverse effect on the quality of the beverage and on the performance of the machine. The invention employs an extracting vessel of tubular form, consisting of: a body (A) supporting a filter (F1), a base (C) and a core (B) supporting the filter (F2), via which the beverage emerges after having passed through the powder contained in (ch2), the upper opening of which is closed off by the sliding piece (D).

Title: Improved electrochemical sensor.
Inventor: NETI RADHAKRISHNA MURTY
IPC: G01N27/49
Filed: 1988-02-24
Abstract: An improved sensor for dissolved oxygen measurement comprising a body having an electrolyte reservoir and electrolyte contained therein and an opening for communication between the exterior of the body and the reservoir and an anode and cathode concentrically disposed in the body adjacent the opening. A thin polymeric membrane permeable to oxygen and impermeable to the electrolyte seals the opening. The working surfaces of the anode and cathode, that is the surfaces adjacent the membrane, are spaced apart from the membrane to define an electrolyte space between the working surfaces and the membrane. A noble metal screen is disposed on the working surface of the anode. Preferably the screen completely covers the anode working surface and a portion of the screen which would normally overlie the working surface of the cathode is cut away so that the cathode working surface is unobstructed. The noble metal screen over the anode surface results in a substantial retention of electrode stability over a period of time as compared to sensors similarly constructed but which do not include the noble metal screen over the anode working surface.

Filed: 1988-07-27
Abstract: Des procédés de codage de signaux d'information sont utiles pour réduire la largeur de bande de signaux transmis et affichés ou pour améliorer la qualité de la perception de ces signaux. Ces techniques mettent en oeuvre des schémas d'échantillonnage variables dans le temps et prennent en considération les caractéristiques du système visuel humain. Pour chaque bloc d'informations, un sous-ensemble de tous les points de données possibles (3) est sélectionné. Un sous-ensemble additionnel de points actifs de données (5) pour lequel des données seront réellement échantillonnées est ensuite sélectionné. Les points actifs sont subdivisés en points pour lesquels des valeurs seront transmises [points x] (7) et en points qui seront échantillonnés mais pour lesquels aucune valeur séparée ne sera transmise [points o] (8). Une association mathématique entre les points x et les points o est effectuée et de nouvelles valeurs (10) à transmettre sont calculées pour les points x. Les paramètres des processus de sélection et d'association sont modifiés de manière non-triviale et le cycle entier est répété avec des blocs ultérieurs de données. En particulier, on peut utiliser ces techniques afin de transmettre des signaux de télévision à haute définition par des canaux à faible largeur de bande.

Inventor: DELEEUW JAMES A
IPC: B01D36/00
Filed: 1989-04-13
Abstract: The device for reducing the volume of an aqueous waste effluent includes a holding tank, a heating tank for receiving waste effluent from the holding tank and including a heater for heating the waste effluent to a predetermined temperature which is below the boiling point of water and high enough to cause a portion of the water to evaporate and be discharged as water vapors, an agitation pump for continuously recirculating the liquids contents of the heating tank and filter units mounted on top of the heating tank for separating solids and particulate matter from the resulting slurry and returning the filtrate to the heating tank. During operation, a transfer pump transfers waste effluent from the holding tank to the heating tank, the heater is turned off after a predetermined heating cycle to allow the slurry to cool to a temperature which promotes precipitation of dissolved solids, a filter pump thereafter periodically introduces a predetermined quantity of the cooled slurry into a filter unit and the filtrate drains back into the heating tank, and the heating, cooling and filter cycles are repeated. The solids collected in the filter unit(s) can be refined to recover valuable metals or disposed of in an appropriate manner.
