  • Patent number: 9863258
    Abstract: A method of forming a structural connection between a spar cap 14 and an aerodynamic fairing 12. A composite comprising an uncured matrix and a compressible solid is applied between the spar cap and fairing and is then compressed and cured to adhere the fairing to the spar cap. The cured matrix composite has a void volume of at least 20%. The high void volume means that as the fairing is compressed into place and compresses the composite, it has space in which to deform so as not to place undue stress on the fairing and to produce a lightweight connection.

  • Patent number: 9863423
    Abstract: A conical impeller with a hub that has a conical surface extending into the interior of the impeller. The hub has spiral, slanting arms which are attached or integrally formed with a plurality of curved blades. The blades can be connected at the bottom by a ring. The intersection of the conical surface of the hub with the blade forms an upward path for fluids and their entrained particles or gases which have been brought into the interior of the impeller to effectively completely be ejected. The discharge edges of the blades and/or the conical surface of the hub may have openings for discharging gas into the fluid. The impeller imparts low shear to the fluid and its components, and the shear is independent or only depends slightly on the size of the impeller. The impeller minimizes or eliminates particle agglomeration and fouling of the impeller. The efficiency of and flow pattern produced by the impeller means that containers don't require the use of baffles.
