Patent number: 8114544Abstract: A method and an apparatus is provided for increasing biofilm formation and power output in microbial fuel cells. An anode material in a microbial fuel cell has a three-dimensional and ordered structure. The anode material fills an entire anode compartment, and it is arranged to allow fluid flow within the anode compartment. The power output of microbial fuel cells is enhanced, primarily by increasing the formation and viability of electrogenic biofilms on the anodes of the microbial fuel cells. The anode material in a microbial fuel cell allows for the growth of a microbial biofilm to its natural thickness. In the instance of members of the Geobacteraceae family, the biofilm is able grow to a depth of about 40 microns.Type: GrantFiled: April 13, 2009Date of Patent: February 14, 2012Assignee: HRL Laboratories, LLCInventors: Tina T.

Patent number: 8075809Abstract: In a method for the production of optical bands with several optical fibers, the surface of the optic fibers in said bands is treated such as to increase the optical damping in sections of the optic fibers. The generated damping may be reliably adjusted, whereby during (or after) the processing of the surfaces a measuring light is introduced into the fiber optic and the light output at the other end of the band is measured by means of a sensor such as a CCD camera. Possible production errors can thus be compensated for during the production process, for example, by an increased process time for the optic fiber. Optical sensor bands can be produced by the above method for application in the bumpers of motor vehicles as recognition sensors for the impact of a pedestrian. Other applications in which the bending of a sensor band is to be determined by optical means are also envisaged.Type: GrantFiled: May 23, 2006Date of Patent: December 13, 2011Assignee: Siemens AktiengesellschaftInventors: Martin Franke, Tobias Happel, Andre Matthias Kwiatek

Patent number: 8071004Abstract: The present invention relates to closures for mating with containers having a threaded finish. The closures comprise a flange and a skirt downwardly depending therefrom. The skirt includes a deformable element formed of a different material than that of the flange and skirt and disposed on an interior surface. The deformable element inner diameter is smaller than the outer diameter of the container, and accordingly deforms upon mating the closure with the container. The container threads impress threads into the deformable element to form threads on the closure. The deformable element is formed of a suitable material. The closures of the present invention provide for the use of high-speed press-on capping equipment.Type: GrantFiled: November 8, 2006Date of Patent: December 6, 2011Assignee: Crown Cork & Seal Technologies CorporationInventors: Min Miles Wan, Emanuel Shenkar, James L.

Patent number: 7980844Abstract: Torques and resin pressures applied to a screw are detected during the forward movement of the screw and coefficients of correlation between the detected torques and resin pressures are calculated. When the check ring is open, the flight of the screw receives resin pressure, and the screw torque increases proportionally to the resin pressure due to resin backflow, so the coefficients of correlation between the screw torques and the resin pressures are higher than a reference value. When the check ring closes, the flight of the screw no longer receive resin pressure, so the screw torque decreases and the coefficients of correlation become lower than the reference value. The check ring is determined to be closed when the coefficients of correlation become lower than the reference value.Type: GrantFiled: May 9, 2008Date of Patent: July 19, 2011Assignee: Fanuc LtdInventors: Junpei Maruyama, Satoshi Takatsugi
