Patent EP-0215022-A1 (EP)
Inventor: NIXON ROBERT J JR
IPC: F16J15/24
Filed: 1986-01-24
Abstract: Une bague d'étanchéité à segments multiples est utilisée dans un équipement rotatif qui comprend un cylindre rotatif (10) de diamètre relativement grand soutenu par un ou plusieurs logements (12, 14) dans une position où son axe est à l'horizontale, avec des joints d'étanchéité installés entre le cylindre et au moins un des logements. Un problème caractéristique de ce type d'équipement est l'impossibilité pratique de fabriquer un cylindre parfait et de le maintenir ainsi. Typiquement, des structures spéciales d'étanchéité sont utilisées pour compenser les irrégularités du cylindre. Cette invention décrit des améliorations de la configuration et du scellement des écarts entre des segments adjacents, à leurs interfaces radiales qui se chevauchent, surtout dans le dessin d'augmenter l'efficacité de l'équipement en éliminant ou au moins en réduisant au maximum le remplissage des écarts avec le matériel traité.

Abstract: Un ensemble de pompe composé d'un rotor (8), d'aubes (10) et d'une bague (10) est disposé entre deux plaques de pression (5 et 12). La plaque de pression (5) s'appuie sur une surface de centrage (20) et est fixée par des boulons au boîtier (1). Des tolérances de serrage très poussées peuvent être obtenues par la fixation axiale de la plaque de pression, qui en même temps sert de couvercle. Une plaque de pression opposée (12) soumise à la pression de refoulement de la pompe possède une chambre de pression (16) limitée par une bague d'étanchéité radiale (22) et par une bague d'étanchéité axiale (23). Cette dernière (23), qui est supportée de préférence par une bague d'appui (25), maintient la plaque de pression (12), même lorsque la pompe est à l'état de repos, contre un ensemble de pompe (8, 10, 11) et serre celui-ci contre la plaque de pression (5). La pompe possède par conséquent des caractéristiques parfaites de démarrage. Pendant le fonctionnement, la pression de refoulement dans une chambre de pression (16) permet l'application des éléments de la pompe. Les pertes dues aux jeux internes sont donc réduites au minimum.

      wherein R¹ is CH₂OH when R is CO₂H, CO₂alkyl or CH₂OH, and R¹ is alkyl when R is alkyl; where in the above alcohol R¹ is CH₂OH, such alcohol compound is treated with an alkyl chloroformate in the presence of base such as an alkali metal alkoxide to form the alcohol
      which undergoes cleavage by treatment with alkali metal, ammonia and acid to form the amino alcohol intermediate. 
     Where in the above alcohol R¹ is alkyl, that is  
      such alcohol may be hydrogenated to form the aminoalcohol intermediate.

Abstract: An impact printer for printing both standard pitch and condensed pitch characters iy disclosed which includes print hammer faces (21, 22) which have a single wide section (21s, 22s) for standard pitch characters and a double wide section (21d, 22d) for printing condensed pitch characters. Using this hammer face one obtains the advantage of high speed when printing standard pitch characters and yet one is able to print condensed pitch characters with the same printer. 
     The face of each hammer is divided into two sections. The first section (21s, 21d). The first section (21s) of each hammer face spans the width of two condensed pitch characters. 
     The hammers are divided into two groups. The first group of hammers has the single width section (22s, 24s, 26s) on the top of the hammer face and the second group of hammers has the single width section (21s, 23s, 25s) on the bottom of the hammer face. Hammers in the first and second groups alternate along the print line and the hammers are aligned so that single width section of all the hammer faces are in a straight line.

Abstract: A steam iron comprises at least two heating elements (4, 6), of which at least one element (6) serves for heating a steam boiler (5) for steam production and at least one other element (4) serves for heating the sole plate. In order to obtain a substantially higher heat trans­fer between the iron and the fabric the iron is constructed in such a way that the heating element(s) for steam pro­duction deliver(s) a higher power than the element(s) for sole-plate heating. Suitably, the total power of the heating elements is at least 1400 W. The transfer of heat from the iron to the fabric is effected by steam condensation within the fabric, which proceeds considerably faster than by thermal conduction.
