IPC: C25D5/50
Filed: 1990-05-22
Abstract: A method for the manufacture of a metal-coated steel strip with improved surface structure, wherein the strip is electrolytically coated with one or more metal coatings and the last-applied coating is temporarily melted by supplying heat to the strip (melting-on), is characterized in that the heat supplied to the strip for effecting the melting-on is generated at least in part by an electric current which is at all times non-zero. The heat supplied to effect the melting-on substantially continuously compensates heat loss from the strip to the surroundings during the melting-on, and may for example be generated by electrical resistance heating using only a direct current or using an alternating current on which is superimposed a direct current. The strips produced are free of the so-called woodgrain effect.

Abstract: The invention relates to a travelling-wave tube with helix (30). The helix is held by clamping in a sleeve (31) and is centred by at least three dielectric bars (32). It has parts (35) of its outer surface in contact with the bars (32). Instead of being produced from a thin strip of a metal which is a good conductor of heat and electricity, the helix (30) is produced from a thin strip consisting of a layer (34) of a first elastic metal covered, at least in the region of all the parts (35) of the helix (30) in contact with the bars (32), with a layer (33) of a second metal which is a good conductor of heat and electricity. The interface resistance between the helix (30) and the bars (32) is then reduced. The invention applies to travelling-wave tubes operating in a wide band and at high average and/or high peak powers. <IMAGE>

Abstract: L'élément d'analyse décrit est conçu pour être utilisé dans un instrument de test analytique automatisé servant à l'analyse d'un échantillon de fluide. L'élément comprend une mince couche poreuse (74) possédant un degré de capillarité élevé, tel qu'un tampon à mailles fibreux soutenu à l'intérieur d'un guide (76) défini par des surfaces (78, 80) contiguës à la couche poreuse. Les dimensions de la couche poreuse et son degré de capillarité sont conçus de façon à assurer le transport par capillarité du fluide à travers la couche. Un distributeur de fluide (68) et une chambre collectrice de fluide (70) sont disposés contigus aux extrémités opposées de la couche poreuse. Le distributeur de fluide (68) se présente sous la forme d'une cuvette (82) dont le fond est pourvu d'un orifice (84) contigu à la couche poreuse (74) et comportant un rebord saillant (106) s'étendant le long d'un périmètre de l'orifice. Le rebord saillant pénètre dans la couche poreuse (74) sur une distance suffisante pour amener le fluide présent dans la cuvette (82) à se propager dans la couche (74) plutôt que le long d'une interface entre une surface de la couche et les surfaces guides (78, 80) qui la maintiennent en place. Des réservoirs peuvent également être prévus dans le logement pour le stockage de réactifs, de fluides, de mélanges et d'échantillons de dilution, de façon à permettre la formation d'un élément d'analyse autonome. Eventuellement et de préférence, une ouverture peut être ménagée dans le logement pour permettre au fluide d'accéder directement à la région centrale de la couche poreuse.

Abstract: An optical microscope includes a revolver (2) for mounting a plurality of objective lenses (0) having different respective magnifications, a stage (3) for holding a specimen to be inspected and being movable in a plane perpendicular to an inspection optical axis of the microscope, a television camera (4) for picking-up an image of the specimen by means of an objective lens (0) which is indexed into the inspection optical axis, and a television monitor (10) for displaying the image of the specimen on a display screen. In order to select an objective lens (0) having a desired magnification, and/or to move the stage (3) with respect to the inspection optical axis, in an automatic manner, a desired region is denoted on the image displayed on the display screen by operating a mouse (11) or similar means. Then, the necessary magnification required is calculated in accordance with a division ratio obtained by dividing an area of the desired region by a full area of the display screen. An objective lens having a magnification which is equal to the required magnification, or which is closest to but smaller than the required magnification, is selected and is automatically indexed into the inspection optical axis. Alternatively, or additionally, at the same time the necessary movement of the stage is calculated and the stage is automatically moved such that a centre point of the desired region becomes centrally placed on the display screen.

Abstract: The fastening clip is placed on two intersecting reinforcing rods (11, 13) or other elongated objects in order to join them and is turned in the direction of the arrow (39) about the axis (21) through approximately forty-five degrees into the position shown in the drawing. After this turning, the first clamping jaws (25) engage on the corresponding reinforcing rods (11, 13) from above and the second clamping jaws (27) engage thereon from below. Since, before the turning, each end portion (37) is arranged at an incline with respect to the plane of intersection (14), during the described turning the first clamping jaws (25) are moved upwards against the spring force. The fastening clip is then held by this spring force in the illustrated position, in which it firmly joins the reinforcing rods (11, 13) to one another. <IMAGE>

Abstract: The pendulum air heater, subject of the invention, is a heat exchanger capable of heating, with low consumption, rooms in houses, offices, shops etc. It consists of a finned pipe (A) oscillating in pendulum fashion, in which an electrical resistor (B) heats and vaporises at atmospheric pressure the water contained. Following the condensation, obtained at the walls, of the steam produced, the vaporisation heat is transferred with great efficiency to the ambient air by virtue, mainly, of the pendulum movement. The pressure is kept below 2 absolute atmospheres. This pendulum movement which characterises the heater, and which is claimed, is maintained by the magneto (C), the current of which is regulated (automatically) by switch.
