Abstract: Une machine du type a deplacement positif pour la detente ou la compression de fluides compressibles, dans laquelle le couple cree ou applique exerce un effet direct sur l'arbre de transmission, les paliers de l'arbre ne sont charges que par les poids de masses rotatives correspondantes, la lubrification etanche n'est pas utilisee, et la structure devrait faciliter l'obtention de faibles pertes. La machine comprend des volumes de travail (5) delimites par un element rotatif (61) et un corps (4), animes d'un mouvement circonferentiel en meme temps que l'element (1), leur direction principale coincidant avec ladite direction circonferentielle. Les volumes de travail (5) sont subdivises en un espace de traitement (6) et un espace de transfert (7) separes par une paroi (15) qui fait partie d'elements rotatifs de reaction (8) perpendiculaires a l'element de travail synchronises avec celui-ci, et dont la solidite est telle qu'elle leur permet de transmettre a l'exterieur de l'element de travail des forces importantes produites par la difference de pression entre lesdits espaces (6, 7). Ces forces peuvent etre compensees par une contre-pression programmee exercee sur une surface (11) de l'element de reaction. Selon le sens de rotation de l'element de travail, le fluide compressible circulant dans la machine est detendu ou comprime. Les vannes rotatives (23) sont utilisees de preference pour assurer une fermeture cyclique de l'espace de traitement (6). La surface instantanee de l'ouverture de vanne peut correspondre sensiblement a la surface instantanee de la paroi de separation (15). La poutre (10) de l'element de reaction formant paroi de separation comprend de preference un seul secteur de transition (77) pour modifier le cycle du procede, et les exigences de synchronisation sont limitees. On utilise de preference des elements d'etancheite (110) legers afin de reduire les effets de pertes provoques par des erreurs de synchronisation. On peut maintenir les fuites qui ne dependent pas de la synchronisation a un faible

Abstract: The invention relates to a polishing method for pressed glass or ground glass articles. As is conventional, polishing is effected in a bath containing sulfuric acid and hydrofluoric acid. Rinsing with a sulfuric acid and/or water washing bath intervenes and follows the polishing process. According to the method of the invention, the sodium and/or potassium ions resulting from the dissolution of glass constituents are removed from the polishing bath by the following means: (a) by adding fluorosilicic acid to the polishing bath, precipitating the corresponding silicofluorides and filtering off the solid matter, (b) by electrolysis in a mercury cell with the formation of sodium- and/or potassium amalgam, (c) by electrolysis in a cell having a cation semi-permeable membrane or (d) with the aid of cation exchangers.

Abstract: Un systeme et un procede de television servent a controler et indiquer des changements de scenes d'ou emanent des rayonnements electromagnetiques, tels que de la lumiere visible. Un systeme de television comprenant une camera de television (10) explore ou analyse la scene par le procede connu du canevas dans une serie de cadres d'images, produisant un signal video a amplitude modulee decrivant la distribution de l'intensite d'energie de la scene. Des circuits d'horloge et de debloquage (42, 44) declenches en synchronisation avec des signaux de synchronisation de la camera de television definissent un ensemble de points ou emplacements a espacements discrets, predetermines du canevas pendant chaque cadre d'image et echantillonnent l'amplitude du signal video a chacun des points ou emplacements definis. Les memes points discrets sont echantillonnes pendant chaque cadre. Un circuit de selection video (20), pendant une succession de periodes d'echantillonnage, effectue l'entree en temps reel d'une representation de chaque echantillon d'amplitude video dans l'un des plusieurs canaux de stockage (24, 26, 28) d'un systeme memoire a multi-canaux comprenant un compteur multi-canaux. Les echantillons d'amplitude video sont affectes aux canaux en fonction de leur valeur d'amplitude. Une collection ou ensemble d'echantillons d'amplitude stockes dans le systeme de memoire a multi-canaux constitue ainsi un profil de la distribution d'amplitude des echantillons video effectues pendant le cadre. Ce premier profil d'amplitude est alors stocke. Le balayage ou analyse, l'affectation et le comptage sont repetes. Par la suite, un circuit de comparaison (74, 116), en reponse au developpement d'un profil ulterieur de distribution d'amplitude, correspondant a un cadre ulterieur selectionne, actionne une alarme (30) en reponse a une difference de seuil predeterminee entre le premier profil (1) et une succession de profils ulterieurs (2) de distribution d'amplitudes developpees.

Abstract: A method and apparatus for depositing a metal on a large-diameter cylindrical bore which passes right through the central portion of a large part. The invention consists in placing and centering the large part (1) between an upper tank (4) and a lower tank (3), so as to define a chamber (8) inside which the bore (2) is disposed and outside which the peripheral portions (9) of the part (1) extend, said chamber being filled with electrolyte. The electrolyte is homogenized and regenerated continuously outside the chamber (8) before being injected in the chamber (8) and before being entrained in a spirally descending motion to the level of the bore (2). The metal deposit takes place under the effect of a direct current which circulates between metal anodes (14) disposed in the bore (2) and the part (1) which serves as a cathode. The invention is used for depositing nickel on the bores of turbine rotor wheels so as to adjust dimensions or prevent fretting corrosion.

Abstract: When polyfunctional ion exchangers based on humic acid are produced, it is desired to bring the humic acid into a form which is particularly stable and resistant to any types of stress. This is achieved by impregnating porous moulded articles with a concentrated aqueous solution of humates present in the sol state at a pH above that of the coagulation point and flocculating the humic acid gel on the moulded article. Ion exchangers produced in this manner can be used for recovering, for example, uranium from aqueous solutions.
