  • Publication number: 20240158492
    Abstract: The present invention provides binding molecules (e.g., antibodies or antigen binding fragments thereof) that specifically bind to and inhibit the biological activity of IL-6 (e.g., human, mouse and non-human primate IL-6). In a preferred embodiment, the antibodies or antigen binding fragments of the invention bind to IL-6 and inhibit its binding to an IL-6 receptor. Such antibodies or antigen binding fragments are particularly useful for treating IL-6-associated diseases or disorders (e.g., inflammatory disease and cancer).

  • Publication number: 20240052863
    Abstract: An assembly for a turbine engine includes at least a first part and a second part, and at least one bolt including a screw engaging with a nut. The screw extends through respective openings in the first part and in the second part. A bearing element of the bolt has an annular flange mounted between the screw or the nut and the first part. The flange has a bearing surface bearing that is tapered and forms an angle (?) with an additional bearing surface of the first part such that only an outer peripheral area of the flange bearing surface comes into contact with the additional bearing surface of the first part, in a non-tightened state of the bolt, the flange deformable such that when the nut is tightened on the screw, a larger area of the flange bearing surface bears on the additional bearing surface of the first part.

  • Publication number: 20240044289
    Abstract: An auxiliary tank for an aircraft turbine engine is provided, and in conjunction with a pump and associated auxiliary lubrication circuit, supplies oil to a reducer when, for example, a phase of free rotation of the fan is detected. Thus, the reducer is always lubricated, even during the phases of free rotation of the fan, thus ensuring a longer life of the reducer gears. The auxiliary tank is arranged with respect to the reducer so that oil is recovered from the reducer at least in part by the auxiliary tank.
