  • Publication number: 20120228978
    Abstract: Various embodiments relate generally to electrodynamic machines and the like, and more particularly, to rotor assemblies and rotor-stator structures for electrodynamic machines, including, but not limited to, outer rotor assemblies and/or inner rotor assemblies with a corresponding stator assembly. In some embodiments a rotor assembly can include magnetically permeable structures having confronting surfaces oriented at an angle to the axis of rotation. A group of magnetic structures can be interleaved with the magnetically permeable structures. The magnetically permeable structures can also include non-confronting surfaces adjacent to which boost magnets are disposed to enhance flux in a flux path passing through magnetic structures that are interleaved with magnetically permeable structures. Further, the rotor assemblies can include a flux conductor shield disposed adjacent to the boost magnets, the flux conductor shield configured to provide return flux paths.

  • Publication number: 20120228976
    Abstract: Various embodiments relate generally to electrodynamic machines and the like, and more particularly, to rotor assemblies and rotor-stator structures for electrodynamic machines, including, but not limited to, outer rotor assemblies. In some embodiments, a stator assembly including field pole members arranged about an axis of rotation and including pole faces at the ends of the field pole members, subsets of the pole faces being disposed within a boundaries of conically-shaped spaces having apexes disposed on the axis of rotation. The rotor assemblies include interior regions in which the subsets of the pole faces are disposed, the interior regions having surfaces external to the boundaries of the conically-shaped spaces. The rotor assemblies also include subsets of magnets interleaved circumferentially with the subsets of magnetically permeable structures and boost magnets disposed adjacent the subsets of magnetically permeable structures.

  • Publication number: 20120228977
    Abstract: Various embodiments relate generally to electrodynamic machines and the like, and more particularly, to rotor assemblies and rotor-stator structures for electrodynamic machines, including, but not limited to, outer rotor assemblies and/or inner rotor assemblies. In some embodiments, a rotor-stator structure includes a rotor structure in which rotor assemblies are arranged on an axis of rotation. A rotor assembly can include an arrangement of magnetic regions each having a portion of a surface that is oriented substantially at an angle to the axis and disposed externally to, for example, a portion of a conically-shaped space centered on the axis of rotation. The rotor-stator structure also can include pole members (e.g., field pole members) having pole faces. A subset of the pole faces can be positioned to confront the arrangement of the magnetic regions to establish air gaps, with the subset of the pole faces being disposed internally to the conically-shaped space.

  • Publication number: 20120219776
    Abstract: A multilayer film that includes at least three layers and is made up of a first layer, a second layer and a third layer, where the first layer is in between the second and third layers. The first layer contains a blend of a second polyolefin and interpolymer resin particles that include a styrenic polymer intercalated within a first polyolefin. The second layer directly contacts a surface of the first layer and includes a first thermoplastic resin. The third layer directly contacts a second surface of the first layer and includes a second thermoplastic resin. The first thermoplastic resin and second thermoplastic resin can be the same or different.

  • Publication number: 20120219813
    Abstract: A film containing a polymer composition that includes from 0.1 to 60% by weight of interpolymer resin particles containing a styrenic polymer intercalated within a first polyolefin and from 40 to 99.9% by weight of at least one second polyolefin. The first polyolefin is present at from 20% to 80% by weight based on the weight of the particles, has a VICAT softening temperature greater than 60° C. and a melt index of from 0.3 to 15 g/10 minutes (Condition I, 190° C., 2.16 kg). The styrenic polymer is present at from 20% to 80% by weight based on the weight of the particles. The interpolymer resin particles have a gel content ranging from 0 to 5% by weight based on the weight of said interpolymer resin particles, a VICAT softening temperature ranging from 85° C. to 115° C., and a melt index value ranging from 0.1 to 6.0 (Condition I).

  • Patent number: 8252956
    Abstract: A new P-N-P ligand in which each phosphorus atom is bonded to two ortho-fluorine substituted phenyl groups is useful in ethylene oligomerizations. In combination with i) a source of chromium and ii) an activator such as methalumoxane; the ligand of this invention may be used to prepare an oligomer product that contains a mixture of hexenes and octenes. The hexenes and octenes produced with this ligand contain very low levels of internal olefins when produced under preferred reaction conditions.
