  • Patent number: 7820092
    Abstract: Methods of forming an elongated composite structural member are provided. One method includes, providing a substantially elongated mandrel having an exterior surface exhibiting a desired geometry. Laying up a first ply of preimpregnated fiber reinforced material over the mandrel. Applying a force to the first ply to establish a desired amount of tension within the first ply and then pressing the first ply onto the mandrel in a conformal manner. This includes passing at least one roller over the mandrel and the first ply while maintaining the desired amount of tension within the first ply. The at least one roller is at least partially complementary in shape with the mandrel.

  • Patent number: 7767128
    Abstract: Method of forming a curved composite structure are provided. In one embodiment, the method includes contacting at least one ply of preimpregnated material on a first surface of a curved mandrel. The first surface of the mandrel has a first radius of curvature. The mandrel further has at least one second surface that has a second radius of curvature. A tension gradient is introduced on the ply adjacent to the first radius of curvature and the ply is then pressed over the curved mandrel to form the curved composite structure.

  • Patent number: 7513769
    Abstract: A method and apparatus are provided for forming elongated composite structural members with a desired cross-sectional geometry as taken transverse to the length of the member. An apparatus may include a base with a substantially elongated mandrel mounted thereon. One or more rollers configured to at least partially complementarily engage the mandrel are configured to roll over and press one or more plies of composite material onto the mandrel. The mandrel may be disposed on a rotary table and configured to exhibit a curved elongated geometry to form at least partially curved or arcuate elongated members. The present invention enables the formation of elongated structural members from resin impregnated materials while maintaining the materials in a substantially uncured state. The formed members may then be cocured with a skin or other composite structure.

  • Publication number: 20030203861
    Abstract: The invention consists of recombinant gene expression vectors and vaccines useful in immunization of a host against an antigen and methods for use of such vectors and vaccines. In particular, the recombinant gene expression vectors of the invention are plasmids, cosmids or viruses which include non-coding, palindromic regions of single or double-stranded DNA or RNA polynucleotides which include at least one cytosine-guanine dinucleotide motif in each palindrome. These polynucleotide regions of each expression vector are immunostimulatory and serve as adjuvants to vaccination protocols against target antigens. Most preferably, the recombinant gene expression vectors of the invention are naked; i.e., non-viral vectors not associated with a delivery vehicle such as a liposome. The invention also includes live viral vaccines wherein the viruses include immunostimulatory polynucleotides of the invention.

  • Publication number: 20020086839
    Abstract: The invention consists of oligonucleotides which inhibit the immunostimulatory activity of ISS-ODN (immunostimulatory sequence oligodeoxynucleotides) as well as methods for their identification and use. The oligonucleotides of the invention are useful in controlling therapeutically intended ISS-ODN adjuvant activity as well as undesired ISS-ODN activity exerted by recombinant expression vectors, such as those used for gene therapy and gene immunization. The oligonucleotides of the invention also have anti-inflammatory activity useful in reducing inflammation in response to infection of a host with ISS-ODN containing microbes, in controlling autoimmune disease and in boosting host Th2 type immune responses to an antigen. The invention also encompasses pharmaecutically useful conjugates of the oligonucleotides of the invention (including conjugate partners such as antigens and antibodies).
