  • Publication number: 20090200906
    Abstract: A rack assembly for use in an oven includes a rack, a rack frame having a left bar, a right bar, and a rear bar, with the rack coupled to the left bar and the right bar. Each left bar and right bar has a front vertical section, a front horizontal section coupled to the front vertical section, a rear horizontal section coupled to the rear of the front horizontal section, and a rear vertical section that is coupled to the rear of the rear horizontal section. The front vertical section extends downwardly from the front of the front horizontal section, the rear vertical section extends upwardly from the rear of the rear horizontal section, the front horizontal section is disposed at a higher vertical level than the rear horizontal section, and the rear bar has opposite ends that are coupled to the rear vertical section of each of the left and right bars.

  • Patent number: 7210909
    Abstract: A first rotor piece includes a first ring provided with a succession of holes and notches. An assembly is formed by a second rotor piece fixed to a third rotor piece. The second piece ends downstream in a second ring including holes. The third piece ends upstream in a third ring including holes. The second and third rings are arranged against each other with their holes in alignment, and are fixed together by first fasteners. The first ring is arranged upstream of and against the assembly so that the notches fit around the first fasteners so that some of the holes of the first ring are aligned with holes of the assembly, with second fasteners fixing the first ring to the assembly.

  • Publication number: 20050025625
    Abstract: The invention relates to a connection between a first piece (D1) ending in a first ring (12) provided with a succession of holes and notches, the axis of the first ring being centred on the axis of rotation of the compressor rotor in order to be attached to the intake of the compressor rotor, and an assembly formed by a second rotor piece (D2) fixed to a third rotor piece (D2). The second piece (D2) forms the intake of the compressor rotor and ends downstream in a second ring (32) comprising holes. The third piece ends upstream in a third ring (32) comprising holes, and the second and third rings are arranged against each other, so as to place their holes in alignment, and are fixed together by first fastening means.

  • Patent number: 6602049
    Abstract: In a turbomachine compressor stator comprising a plurality of variable-pitch vanes (36), each vane mounted in rotation, about an axis of pivoting (38), in a wall (34) forming a surface of revolution about a longitudinal central axis of rotation of the turbomachine (32), being inclined by a specified angle (&agr;) with respect to a plane perpendicular to this longitudinal central axis, there is provision for this wall to be machined locally opposite an end part of each vane (42) so as to form a spherical portion or pocket (40) whose center is positioned on the axis of pivoting and whose radius is determined so as to ensure, over the entire range of operation of the vane, a predetermined minimum clearance between this end part of each vane and the opposite machined spherical pocket while limiting the depth of machining of this pocket.
