Patent EP-0402832-A1 (EP)
Inventor: DIEGELMANN MICHAEL DR
IPC: B23K26/00
Filed: 1990-06-11
Abstract: Method of directing the temperature profile at soldered joints during laser soldering by sensing the moment at which the solder melts. Methods according to the prior art sense the moment at which the solder melts by detecting the transformation point in the temperature-time curve. The melting temperature can be detected within certain tolerance limits. The reproducibility of the relative temperature measurements has hitherto been unsatisfactory on account of the spread in the solder volume of various soldered joints and on account of different surface textures of the solder. So that a congeneric method can be carried out irrespective of the solder volume and surface texture of the respective solder, an ultrasonic signal is detected via an ultrasonic sensor which is coupled to the workpiece or its holder, which ultrasonic signal is produced in the workpiece by the irradiation of the soldered joint by laser light modulated in intensity and exhibits a large drop in amplitude when the melting temperature is reached. Since this drop in the amplitude of the ultrasonic signal covers a narrow temperature range, the moment at which the solder has melted is detected in an exceptionally precise manner.

Abstract: In plants with fossil combustion, carbon dioxide and, if appropriate, water are ultimately formed as a combustion product. These two products are as a rule released as waste gases into the atmosphere. The carbon dioxide produced then impedes the heat emission from our Earth and causes the so-called greenhouse effect. The invention is based on the object of largely suppressing the release of carbon dioxide from a gas-and-steam power plant into the atmosphere. In a gas-and-steam turbine power plant with a gasifier (18, 238) upstream of the combustion chamber (14, 234), it is provided according to the invention that the raw gas (RG) from the gasifier (18, 238) is dedusted, cooled, purified and enriched with water and shift-converted. The carbon dioxide (CO2) and, if appropriate, the sulphur compounds are separated off by a scrubbing agent. The carbon dioxide is disposed of, for example passed into a dry ice plant (66, 290) or otherwise industrially utilised. The pure gas (GG) largely free of carbon dioxide and containing essentially hydrogen is fed as fuel to the combustion chamber (14, 234) of the gas turbine. The invention is applicable especially to gas-and-steam turbine power plants, but can also be used in pure gas turbine power plants. <IMAGE>

Abstract: A method is described for the manufacture of a seal of microporous PTFE for installation between planar sealing surfaces. An extruded, stretched rectangular profile, which is wider than it is high, serves as the starting material. By precompressing the profile transversely to the direction of the screw forces, a precompressed seal is produced, the width of which is smaller compared with the width of the extrudate. In the case of such a precompressed seal, the final state is achieved by applying the screw forces in the shortest time. <IMAGE>

Abstract: 2.1. To close folding boxes 11, adhesive tapes 10 are automatically applied to closure sides 12 during transport of the boxes. The adhesive tape 10, which is drawn off from a roll, is pressed onto the folding box 11 under tension by pressure rollers. A pressure roller 26 serves to press an end section 39 of the adhesive tape 10, which projects at the rear, initially beyond the folding box 11, against a transversely directed side surface 40 of the folding box 11. 
<??>2.2. During use of adhesive tapes 10 with unstable support material, there is a danger of formation of corrugations and of curling in particular of the end regions of the adhesive tape 10. To this end, a holding-smooth member in the form of a stationary suction head 41 is arranged. The adhesive tape 10 slides along the latter in such a manner that, in the end phase, the projecting end section 39 is held temporarily in a smooth position until taken over by the associated pressure roller 26.

Abstract: A diagnostic x-ray machine including a reciprocating grid (30) reduces grid lines, in the radiographic image, formed as a result of velocity variations in the reciprocation of the grid, principally at the points of grid reversal. An x-ray source (10) produces a beam (24) of x-ray radiation along a major axis directed through a body (18) and the grid (30). A reciprocating mechanism (Fig. 2, 52-64) moves the grid (30) within a plane perpendicular to the major axis between a first limit and a second limit and the x-ray beam is modulated synchronously with the grid motion to reduce the grid image at points of grid speed variation. The modulation is achieved, for example, by a chopper (18,16,14) or by varying the x-ray tube voltage.

Abstract: Un analyseur de films cinématographiques génère un signal de télévision à haute définition à partir d'une combinaison d'une composante de détail à haute définition et une pluralité de composantes en couleurs à définition moins élevée. La composante de détail est obtenue à partir d'un signal de luminance généré par un capteur à antennes colinéaires (44) possédant une définition des lignes adaptée à l'analyse à haute définition. Les composantes couleurs à définition moins élevée sont obtenues à partir de trois capteurs à antennes colinéaires (36r, 36g, 36b) à basse résolution produisant des signaux rouges, verts et bleus flous. Le réseau de luminance est divisé en segments de taille semblable (44a, 44b, 44c, 44d); plusieurs registres (48a, 48b, 48c, 48d) sont ensuite utilisés afin d'atteindre le débit nécessaire à l'analyse à haute définition. Les photosites en couleurs sont plus grands que les photosites de luminance afin que le rapport signal/bruit soit amélioré. En faisant en sorte que le nombre de photosites dans chaque segment de luminance soit un sous-multiple du nombre de photosites dans le réseau en couleurs, un signal d'horloge commun (42) est utilisé pour extraire tous les réseaux linéaires. De multiples lignes de luminance sont donc sortis pour chaque ligne de couleur, livrant ainsi une définition moins élevée à la fois dans les sens d'analyse vertical et horizontal.

Abstract: A spinning ring (1) of a ring spinning machine having an oblique flange (11) is designed so that the running surface (13) has, on the inside of the spinning ring, a radius (R2) of approximately 25 mm which merges into a radius (R1) amounting to at least 1 mm at the point of the smallest inside diameter (D) of the spinning ring (1). The bead (12%) on the running part (12) of the spinning ring (1) has a height (H) which is at most 1/3 greater than the thickness (K) of the bead. Travellers having small outer dimensions can thereby be used, with the result that a greater wire thickness of the traveller material can be selected, as a consequence of which the service life of the traveller in the ring spinning machine is increased substantially in comparison with the state of the art. The radius (R1), large in comparison with the state of the art, and the comparatively small radius (R2) lead to an approximately constant surface pressure between the ring traveller and spinning ring and allow stable running during the spinning process. <IMAGE>
