Publication number: 20070177937Abstract: A shaft assembly includes a metallic portion and a ceramic portion. In a disclosed example, a ceramic shaft has a generally conical end that is at least partially received within a generally conical recess in one end of a metallic shaft. The recess has a first portion that has an inner surface that is received directly against a corresponding outer surface on a section of the ceramic shaft conical portion. A second portion of the recess is radially spaced from the ceramic shaft and provides a controlled gap within which a braze alloy is maintained. In one example, the second portion has an axial length that is more than twice a radial depth of the second portion. In another example, a transition surface between the first and second portions of the recess has a linear profile.Type: ApplicationFiled: January 30, 2006Publication date: August 2, 2007Inventors: John Holowczak, Constance Bird, Gary Sanders, Anthony Giamei, Robert Telakowski, Edward Rothman

Patent number: 5952232Abstract: The present invention relates to methods and compositions for delivery of a compound, most preferably a polynucleotide, into the cytoplasm of a cell by means of a microparticle, fabricated from a pH-sensitive hydrogel in collapsed phase, and having a size and physical characteristics compatible with uptake via a clathrin-coated pit on the cell surface. The trigger pH at which the hydrogel expands is lower than the physiological pH of the extracellular environment, allowing the microparticle, which comprises the compound to be delivered, to maintain its compact size prior to cellular uptake, thereby providing the additional benefit of protecting the comprised compound from degradation. This protective feature is particularly beneficial in embodiments in which a polynucleotide or a peptide is being delivered. Following uptake via a clathrin-coated pit, the microparticle then enters the intracellular endocytic pathway, where it is subjected to a progressive decrease in pH.Type: GrantFiled: September 17, 1998Date of Patent: September 14, 1999Inventor: James Edward Rothman

Patent number: 4236873Abstract: A large wind turbine rotor blade having a filament wound composite spar securely mounted to a support structure in a manner by which blade loads are transmitted via redundant load paths. Concentric inner and outer metallic adapter sleeves are bonded to the inboard end of the blade spar, and the adapter sleeves and blade spar are joined by a first series of shear bolts and nuts which pass radially through the spar. A second series of radially extending bolts and nuts join the inner and outer sleeves slightly inboard of the end of the spar. The end of the spar is of slightly reduced diameter forming a conical surface which interacts with the inner and outer sleeves to produce a positive lock when the blade is subject to centrifugal loads. The outer sleeve is adapted to be connected to the support structure by conventional techniques such as by a plurality of bolts which extend axially into the butt end of the outer sleeve.Type: GrantFiled: September 20, 1978Date of Patent: December 2, 1980Assignee: United Technologies CorporationInventors: Robert Sherman, Edward A. Rothman, William Mandelbaum

Patent number: 4010884Abstract: A filament-reinforced composite article is fabricated from monolayer boron fiber tapes and laminates of titanium. The tapes which have the boron fibers attached to an aluminum foil are positioned in a multi-ply layup with interleaved titanium laminates in the form of foils or screening. The layup is subjected to heat and pressure in a diffusion bonding process to compact the layup materials and bond the fibers in the matrix of aluminum and titanium. The titanium in the matrix improves the impact load resistance of the article by improving ductility and impact strength.Type: GrantFiled: November 20, 1974Date of Patent: March 8, 1977Assignee: United Technologies CorporationInventor: Edward A. Rothman
