Patent number: 8517664Abstract: In one example, a turbocharger for an internal combustion engine is described. The turbocharger comprises a casing containing an impeller having a full blade coupled to a hub that rotates about an axis of rotation. The casing includes a bleed port and an injection port. The full blade includes a hub edge, a casing edge, and a first distribution of angles, each angle measured between the axis of rotation and a mean line at the hub edge at a meridional distance along the hub edge. The full blade includes a second distribution of angles, each angle measured between the axis of rotation and a mean line at the casing edge at a meridional distance along the casing edge. Further, various systems are described for affecting the aerodynamic properties of the compressor and turbine components in a way that may extend the operating range of the turbocharger.Type: GrantFiled: January 19, 2010Date of Patent: August 27, 2013Assignee: Ford Global Technologies, LLCInventors: Harold Huimin Sun, Dave Hanna, Jizhong Zhang, Liangjun Hu, Eric M.

Patent number: 7204989Abstract: A highly immunoreactive viral peptide, pE2, is disclosed which is derived from the carboxy-terminal end region of ORF2 region of the hepatitis E virus (HEV) genome. A unique feature of the novel pE2 peptide is that it possesses conformational antigenic determinants which are only exposed when monomers of the peptide associate with one another through non-covalent interactions to naturally form homodimers. The novel pE2 peptide is proven to be highly reactive with sera from patients having current or past infection with HEV which suggests that the homodimer may mimic certain structural features of the HEV capsid protein. Furthermore, the antigenic activity of the pE2 peptide is strictly conformational in nature and therefore, exhibits immunochemical reactivity only when the peptide exists in a dimeric form. Consequently, the antigenic activity is lost upon dissociation of the dimers, but the activity is restored when the monomers reassociate to form dimers.Type: GrantFiled: September 28, 2000Date of Patent: April 17, 2007Assignee: Yang Sheng Tang Company LimitedInventors: Hon Mun Ng, Stanley Im, Jizhong Zhang
