20140292940 | Process for Preparing a Dispersion, Dispersion, Use and Method - A process for preparing a dispersion comprising the stages: i) providing a dispersion comprising a particulate solid, a liquid medium and a dispersant having cross-linkable groups and a weight averaged molecular weight of from 1,000 to 70,000; and ii) cross-linking the dispersant in the presence of the particulate solid and the liquid medium thereby preparing a dispersion of an encapsulated particulate solid, wherein the cross-linking is performed such that 0.01 to 0.5 mmoles of cross-linkable groups in the dispersant are cross-linked per g of dispersant; said process also comprising at any stage: iii) adding a metal chelating agent to the dispersion; and after stage iii) the stage of: iv) removing at least some of the metal chelating agent from the dispersion. | 10-02-2014 |

20090285989 | Dispersion, Ink, Process, Use and Dispersant - An aqueous dispersion comprising water, pigment particles and a polymeric dispersant comprising monomer repeat units from polymerising one or more ethylenically unsaturated monomers, said dispersant having one or more boronic acid groups. The dispersion is useful for preparing ink jet printing inks having improved durability and highlighter smear fastness when printed onto paper. | 11-19-2009 |
20120287201 | PROCESS FOR PREPARING A DISPERSION OF A PARTICULATE SOLID - A process for preparing a dispersion of a particulate solid is described, which comprises dispersing a particulate solid with a dispersant and a liquid medium, wherein the dispersant is a random copolymer obtained from the copolymerisation of a composition comprising: i) optionally one or more monoethylenically unsaturated hydrophilic monomers, ii) one or more monoethylenically unsaturated hydrophobic monomers, iii) one or more di- and/or higher-ethylenically unsaturated monomers, and iv) one or more chain transfer agents wherein at least one of the chain transfer agents has one or more hydrophilic anionic groups. | 11-15-2012 |

20110034775 | Surgical Retention Port and Method of Use - A surgical retention port particularly useful as an arthroscopic port for shoulder surgery is provided. The surgical retention port has an inner cannula defining a throughbore, a plurality of rotatable fingers coupled to the inner cannula, and an outer cannula extending around the inner cannula. Rotation of the inner cannula relative to the outer cannula causes the rotation of the fingers from a first position where the fingers assume a collapsed configuration to a second position where the fingers assume an extended or open configuration. | 02-10-2011 |
20110306841 | Surgical Retention Port and Method of Use - A surgical retention port particularly useful as an arthroscopic port for shoulder surgery is provided. The surgical retention port has a long pointed instrument such as a trocar or obturator, an inner cannula extending around the pointed instrument, a plurality of rotatable fingers coupled to the inner cannula, and an outer cannula extending around the inner cannula. In one embodiment of the invention, the inner cannula and long pointed instrument are keyed such that rotation of the long pointed instrument can effect rotational movement of the inner cannula. Rotation of the inner cannula in turn causes the rotation of the fingers from a first position where the fingers assume a collapsed configuration to a second position where the fingers assume an extended or open configuration. | 12-15-2011 |

The surgical retention port has an inner cannula defining a throughbore, a plurality of rotatable fingers coupled to the inner cannula, and an outer cannula extending around the inner cannula. Rotation of the inner cannula relative to the outer cannula causes the rotation of the fingers from a first position where the fingers assume a collapsed configuration to a second position where the fingers assume an extended or open configuration. | 08-29-2013 |
