  • Patent number: 11333253
    Abstract: A magnetic seal assembly comprises a metallic annular wear seal. A magnetic seal has a magnetic annular body adjacent to and attracting the wear seal into contact against a contact face thereof. A retainer ring is connected to a surface to the magnetic seal, the retainer ring having a coefficient of thermal expansion different than a coefficient of thermal expansion of the annular body, the coefficient of thermal expansion of the retainer ring selected to constrain a thermal expansion of the annular body. A method for controlling a thermal expansion of a magnetic seal assembly is also provided.

  • Patent number: 10876578
    Abstract: A bearing alignment assembly comprises an outer ring. An inner ring assembly is disposed radially inwardly of the outer ring and cooperating therewith to form a roller volume. The inner ring assembly has a forward inner ring and an adjacent aft inner ring cooperating to provide an inner surface of the inner ring assembly. The forward inner ring includes axial grooves extending axially along and circumferentially spaced around a forward portion of the inner circumferential surface of the inner ring assembly.

  • Patent number: 9145640
    Abstract: A process using a multicomponent enzyme preparation to treat chips that have been crushed using a device that combines shear and compressive forces where treatment occurs mainly during decompression and reduces the specific energy consumption and/or increasing production of subsequent refining while maintaining or increasing handsheet physical properties. The enzyme preparation is to have a major endoglucanase activity, a significant mannanase activity and a slight cellobiohydrolase activity. This enzyme mixture is prepared from a genetically modified strain of Trichoderma reseii.

  • Patent number: 9127401
    Abstract: A process using a multicomponent enzyme preparation to treat screened once refined pulps and reduces the specific energy consumption and/or increasing production while maintaining or increasing handsheet physical properties. The enzyme preparation has a major endoglucanase activity, a significant mannanase activity and a relatively small cellobiohydrolase activity. This enzyme mixture is prepared from a genetically modified strain of Trichoderma reseii.

  • Patent number: 4099432
    Abstract: A copying machine, in this case a lathe, includes a set of roughing stops carried on an indexable hub, and a fixed finishing stop. A rotary hydraulic motor is provided between a rod on which the template is rockably supported and a lever which is adapted to contact one of a series of roughing stops carried by a hub. The rod carrying the template also carries a second lever arranged to contact a micrometric finishing stop, so that the swinging of the template about the axis of the rod is controlled by selection of an appropriate one of the series of roughing stops to be engaged by the first mentioned lever.

  • Patent number: 3979634
    Abstract: In order to reduce to a minimum the internal diameter of the focusing coils 30 of travelling-wave tubes, the electrodes of the electron gun 10 thereof terminate in cylindrical portions 26, 31 whose external surfaces are in contact, via rings 27 and 28, with metal washers 18, 19 separating insulating cylinders 14, 15, 16 stacked one on top of the other and forming a socket for the casing of the tube containing gun 10. The contact is such that the radial dimensions are minimal and high insulation can be provided between the components. Application to high-power, high-voltage travelling-wave tubes.
