| 20090272493 | LABELLER - A labeler includes a waste liner rewind wheel for taking up the release liner after it has been separated from the labels, and a print mechanism positioned along the label path for real-time printing of a desired print material on the labels. In one embodiment, the waste liner rewind wheel includes a mechanism for adjusting the speed of the rewind wheel as the amount of waste liner on the rewind wheel increases, while maintaining sufficient tension on the waste liner to pull the waste liner onto the rewind wheel. In another embodiment, the print mechanism is mounted to the frame along the label path, such that the print mechanism is capable of printing on the labels as they are moved past the print mechanism. The labeler may additionally include an encoder for registering the position of the label web with respect to the print mechanism. | 11-05-2009 |
| 20100101731 | LABELLER - A labeler is supported on a frame and includes a waste liner rewind mechanism. The frame may be a two-piece frame, wherein each piece supports a plurality of labeler components. A waste liner rewind wheel is rotatably mounted on one of the frame members, and is capable of supporting the release liner of the label web after the labels have been removed and applied to items. A rewind drive is connected to the waste liner rewind wheel for advancing the waste liner rewind wheel to wind the release liner about the waste liner rewind drive wheel. The rewind mechanism actuates the rewind drive as a function of the amount of tension on the release liner. The labeler may also include a print mechanism positioned along the label web path for printing a desired printed information on the individual labels. | 04-29-2010 |

| 20110008804 | ANGIOPOIETIN-1 AND -2 BIOMARKERS FOR INFECTIOUS DISEASES THAT COMPROMISE ENDOTHELIAL INTEGRITY - The invention relates to a method of identifying a subject having, or at risk of developing, an infectious disease state wherein endothelial integrity is compromised comprising: (a) determining a test ANG-1 level in a sample from a subject; and (b) comparing the test ANG-1 level to a control level wherein lower test ANG-1 level compared to the control level is indicative of the subject developing said infectious disease state. | 01-13-2011 |

| 20090247706 | Continuous extrusion process for producing grafted polymers - A continuous extrusion process for the functionalization of polymers through reactive extrusion. The process uses a continuous extrusion reactor comprising at least two sequential, very closely-coupled, independently driven screw extruders having a total effective length to diameter ratio greater than 60 to 1 and as high as 112 to 1 and providing greatly extended reaction times for efficiently producing a grafted polymer having a high level of functionalization. Drying of the polymer feed is performed in the continuous extrusion reactor. Multiple injections of reactants may be provided. Shear modification of the molecular weight of the grafted polymer is performed in the continuous extrusion reactor after the functionalization reactions. A continuous extrusion reactor and a grafted polymer having a high level of functionalization are also disclosed. | 10-01-2009 |
| 20100048838 | ISOOLEFIN-DIOLEFIN PRODUCTION PROCESS AND APPARATUS THEREFORE - In an isoolefin-diolefin rubber production process (e.g. a butyl rubber production process), the cold rubber slurry produced in the reaction vessel is transported from the reaction vessel to the flash tank during which time the cold slurry may be expressed to separate at least part of the cold liquid reaction medium from the isoolefin-diolefin rubber. The separated cold liquid reaction medium is transported off stream, for example by a mechanical filter, where it can be recycled back into the reaction vessel and/or where it can be used to cool a feed stream or streams of the reaction components. The isoolefin-diolefin rubber and the residual liquid reaction medium are transported to a flash tank for further processing. The ability to separate and recycle cold liquid reaction medium makes the process more economical. In one aspect, the slurry may be transported from the reaction vessel to the flash tank by a self-cleaning fully intermeshing co-rotating twin screw extruder, which helps overcome the problem of plugging due to rubber sticking to the surfaces of the slurry transfer apparatus. | 02-25-2010 |

| 20110257342 | COMMON SOLVENT PROCESS FOR PRODUCING HIGH MOLECULAR WEIGHT HALOBUTYL RUBBER - An integrated process for the solution polymerization and subsequent halogenation of butyl rubber in a common medium is disclosed. The process comprises providing a solution polymerization reactor containing a C6 medium mixed with a monomer mixture comprising at least an isoolefin monomer and a multiolefin monomer in a mass ratio of monomer mixture to medium of from 61:39 to 80:20. Once polymerized, residual unreacted monomer mixture is separated from the rubber solution using a distillation process. The residual monomers may then be purified and recycled back into the reactor. The separated rubber solution is then halogenated. The process obviates the need for separating the rubber from the medium following polymerization, then re-dissolving it in another solvent for halogenation, thereby saving energy cost. The process optionally employs heat exchangers for the reactor feed streams to further reduce energy consumption. | 10-20-2011 |
