  • Publication number: 20190232582
    Abstract: In an example, a method of forming a composite material includes embedding a plurality of conductive-magnetic particles in a matrix material. The method also includes applying, using a magnetic device, a magnetic field to the plurality of conductive-magnetic particles in the matrix material to move the plurality of conductive-magnetic particles into an alignment in which a longitudinal axis of each conductive-magnetic particle is parallel to a direction of the magnetic field. The method further includes, while applying the magnetic field, curing the matrix material to a hardened state in which the alignment of the plurality of conductive-magnetic particles is fixed in the matrix material.

  • Publication number: 20120088848
    Abstract: Methods and compositions for the generation of polypeptides having varied material properties are disclosed herein. Methods include means for initiating the polymerization of aminoacid-N-carboxyanhydride (NCA) monomer by combining the monomer with an amido-containing metallacycle, for making self assembling amphiphilic block copolypeptides and related protocols for adding oligo(ethyleneglycol) functionalized aminoacid-N-carboxyanhydrides (NCAs) to polyaminoacid chains. Additional methods include means of adding an end group to the carboxy terminus of a polyaminoacid chain by reacting an alloc-protected amino acid amide with a transition metal-donor ligand complex to forming an amido-amidate metallacycle for use in further polymerization reactions. Novel compositions for use in peptide synthesis and design including five and six membered amido-containing metallacycles and block copolypeptides are also disclosed.

  • Publication number: 20050189254
    Abstract: A gift that includes simulated pharmaceutical packaging which presents a humorous or thoughtful interplay between the packaging and the surprise contents within the packaging. The packaging includes at least a container and a lid which are substantially opaque to at least partially obscure the contents of the container from plain view. The container is accompanied by written material, applied to the container and/or a bag in which the container may be placed, and the written material is used to set up the interplay with the surprise contents. The invention further includes a method of providing such a gift.

  • Patent number: 4121504
    Abstract: A linear positioning cylinder drive has a piston connected at one end to a load and at the other end to a cable. The cable is secured to a pulley secured to a shaft urged in a takeup direction by a coil spring or hydraulic motor. The piston is moved by a hydraulic pump through a servo valve actuated by a circuit controlled by a transducer driven by the shaft. In one embodiment, the transducer is rotary and in another embodiment the transducer is linear.
