Patent number: 8312717Abstract: An externally heated engine is provided which has a piston and a displacer. The position of the piston can be adjusted by a yoke and disk assembly on one end of a link and spacers and gaskets in the cylinder. The relative position of the displacer with respect to the piston can be changed by changing the relative position of a pair of disks in the crankshaft assembly. The displacer is caused to reciprocate by a link which is moved by a displacer cam assembly. The displacer cam assembly includes a first cam and a second cam. The first cam and the second cam each have a groove path. The displacer link follows the groove path of the cams to cause the displacer to dwell at the two ends of its stroke and to move rapidly from one end to the other.Type: GrantFiled: May 22, 2009Date of Patent: November 20, 2012Assignee: Renewable Thermodynamics, LLCInventors: Gary P.

Patent number: 8298677Abstract: The invention generally relates to fluorescent nanoparticles and more specifically to silica-based fluorescent nanoparticles of less than 30 nm with covalently attached organic dyes. The invention provides a fluorescent monodisperse silica nanoparticle comprising fluorophore center core and a silica shell wherein the radiative properties of the nanoparticle are dependent upon the chemistry (composition) of the core and presence of the silica shell. In one aspect of the invention, the core-shell architecture provides an enhancement in fluorescence quantum efficiency. The invention generally provides control of photophysical properties of dye molecules encapsulated within silica particles with sizes down to 30 nm and below. This control is accomplished through changes in silica chemistry and particle architecture on the nanometer size scale and results in significant brightness enhancement compared to free dye.Type: GrantFiled: November 26, 2003Date of Patent: October 30, 2012Assignee: Cornell Research Foundation, Inc.Inventors: Ulrich Wiesner, Hooisweng Ow, Daniel R. Larson, Watt W. Webb

Patent number: 8239829Abstract: A method of using co-routines to implement a function-like interface between a BASIC program and the points in the system where SIP and SDP data (for example) are to be modified. This co-routine interface is intuitive from the end-user's perspective, and both real-time efficient and flexible from the system designer's perspective, and is applied to provide user-customized SIP and SDP modifications in an easy-to-use way that gives the end-user great flexibility while protecting the system from the undesirable side-effects that could result from a tightly coupled co-routine interface.Type: GrantFiled: August 8, 2008Date of Patent: August 7, 2012Assignee: Redcom Laboratories, Inc.Inventors: Charles J. Breidenstein, James W. Delmege

Patent number: 8225942Abstract: An influent feed system for directing the influent liquid via hydraulic energy to scour the surface of primary treatment tank walls and base to move the scoured solids to a sludge trough. Scouring action takes place during periods of low liquid levels in the tank. The system comprises two identical, adjacent tanks sharing a common distribution box. Either or both of the tanks are in use at any given time. The tank in use will be empty occasionally each day. Influent feed troughs disposed transversely in each tank directs solids towards a sludge hopper in the tank bottom. The IFTs extend over the width of the tank to provide scouring of the entire end wall and floor surface. Each IFT has a sump with a valved discharge piped directly to the sludge trough, and the floor of each IFT is sloped towards the sump to facilitates draining of solids.Type: GrantFiled: January 12, 2010Date of Patent: July 24, 2012Assignee: Trans Terra CorporationInventor: Terry Wright

Patent number: 8206677Abstract: Method of treating sodium contained in the interconnected open pores of a structure placed in a cladding, the pores furthermore containing a radioactive substance. The method comprises the following successive steps: a) at least two slits are made over the entire length of the cladding; b) the sodium is converted to sodium carbonate by a carbonation reaction by bringing the structure into contact, via the slits, with a reactive gas mixture comprising steam, carbon dioxide and a gas inert with respect to sodium, in such a way that the expansion of the carbonate causes the cladding and the structure to open starting from the slits and results in the carbonation reaction propagating into the structure.Type: GrantFiled: June 24, 2009Date of Patent: June 26, 2012Assignee: Commissariat a l'Energie Atomique Et Aux Energies AlternativesInventors: Serge Sellier, Janick Verdelli, Joel Godlewski, Michel Soucille, Sandrine Poulain

Patent number: 8156947Abstract: A system for carrying out a pedicure wherein a conventional pedicure is closely simulated while protecting the foot from microbial infection and harsh chemicals. The foot is encased in a waterproof sock containing appropriate liquid conditioners for softening the skin. The encased foot is placed in a warm, recirculating water bath for a period of time. The foot is then removed from the bath, the sock is removed from the foot and discarded, and a conventional pedicure trimming process is carried out. The skin of the foot is thus protected from any contact with the water bath, while the soothing, stimulative, and otherwise pleasurable effects of the recirculating warm water are provided as in a conventional pedicure process.Type: GrantFiled: February 2, 2010Date of Patent: April 17, 2012Inventors: Deanne Viola, Lena Golubkov
