| 20100170612 | PARTICLE LITHOGRAPHY METHOD AND ORDERED STRUCTURES PREPARED THEREBY - Particles having a non-uniform property, such as non-uniform charge, can be used to form complex yet controlled particle assemblies. In one method of fabrication, particles are located on a substrate, and a surface treatment applied to the exposed portion of the particle surface. The surface treatment modifies the particle properties within the exposed portion. One or more lithographed regions are not exposed to the surface treatment, providing spatial selectivity in inter-particle bonding after the particles are removed from the substrate. | 07-08-2010 |
| 20100289736 | ELECTROPHORETIC PARTICLES, AND PROCESSES FOR THE PRODUCTION THEREOF - An electrophoretic medium comprises at least one electrically charged particle dispersed posed in a fluid. The electrically charged particle comprises an inorganic black pigment having a surface area of at least about 7 m | 11-18-2010 |
| 20110012825 | ELECTROPHORETIC PARTICLES AND PROCESSES FOR THE PRODUCTION THEREOF - In electrophoretic media, it is advantageous to use pigment particles having a polymer chemically bonded to, or cross-linked around, the pigment particles, the polymer comprising repeating units derived from a fluorinated acrylate or fluorinated methacrylate monomer. The polymer desirably has a branched chain structure with side chains extending from a main chain. Desirably, the fluorinated acrylate or fluorinated methacrylate monomer comprises from 1 to 5 mole per cent of the polymer. | 01-20-2011 |

| 20090102099 | Injection Molding Apparatus Having Magnetic Valve Pin Coupling - A magnetic coupling for an injection molding apparatus, such as a hot half or hot runner, includes a first magnetic part for connection to an actuator, a valve pin plate, or the like and a movable second magnetic part for connection to a valve pin. The first magnetic part and the second magnetic part are coupled by a magnetic force. The first magnetic part can be part of the actuator. The second magnetic part can be part of the valve pin. A valve pin plate can be provided for a plurality of valve pins. | 04-23-2009 |
| 20090148551 | Injection Molding Apparatus With Plate Actuation of Valve Pins - An injection molding apparatus includes a back plate, a driven pulley connected to the back plate and rotatable with respect to the back plate, a screw connected to the driven pulley to rotate with the driven pulley, a motor having an attached drive pulley, a belt or chain coupling the driven pulley and the drive pulley, a valve pin plate, a nut connected to the valve pin plate and mated with the screw, at least one valve pin connected to the valve pin plate, a manifold fixed with respect to the back plate, and at least one nozzle connected to the manifold. The valve pin extends through the nozzle to control flow of molding material. The screw can be a ball screw and nut can be a ball nut. The screw can have one portion connected to the driven pulley and another portion connected to a mold plate in a rotatable manner. The valve pin plate may be an assembly with an upper plate, a lower plate, and at least one valve pin holder fixed between the upper plate and the lower plate, the valve pin being fastened to the valve pin plate assembly with the valve pin holder. The positions of the screw and nut can be reversed. | 06-11-2009 |
| 20100233310 | Thermal Shroud and Method of Making Same - An injection molding hot runner nozzle and a method of making such a nozzle are disclosed that improves heat transfer along the length of the nozzle. The nozzle includes a nozzle body and a heating element located on an outer surface of the nozzle body having a form-fitting thermally conductive shroud that conforms to a profile of the nozzle and the heating element. | 09-16-2010 |
| 20110008532 | METHOD OF MANUFACTURING HOT-RUNNER COMPONENT AND HOT-RUNNER COMPONENTS THEREOF - A method of manufacturing a hot-runner component includes providing a laser assembly, manufacturing a hot-runner component portion of a metallic material, introducing a property enhancing material to the hot-runner component portion, melting the property enhancing material onto the hot-runner component portion using a laser beam emitted from the laser assembly, and solidifying the melted property enhancing material on the hot-runner component portion. | 01-13-2011 |
