Polymer coated carbon products and other pigments and methods of making same by aqueous media polymerizations or solvent coating methods

Abstract: A polymer coated modified carbon product is described wherein the polymer at least partially coats a modified carbon product. The modified product preferably has at least one organic group attached to the carbon product and the organic group is preferably substituted with an ionic, ionizable, or polar group for preparation in polar or aqueous based media. Methods of making the polymer coated modified carbon product are also described, such as by aqueous-based or solvent free polymerization methods, organic solvent based polymerization methods, or solution coating methods. Polymeric products and masterbatches containing the polymer coated modified carbon products are also described as well as methods to improve properties such as impact properties and tensile properties.

Aerogel and hollow particle binder composition, insulation composite, and method for preparing the same

Abstract: The invention provides an aerogel-hollow particle binder composition comprising an aqueous binder, hydrophobic aerogel particles, and hollow, non-porous particles, as well as an insulation composite comprising the aerogel-hollow particle binder composition, and a methods of preparing the aerogel-hollow particle binder composition and insulation composite.

Drill rig apparatus

Abstract: There is disclosed herein a mobile well drilling rig apparatus adapted for rapid assembly and disassembly thereof. The drilling rigs of the invention comprise a trailerable telescoping mast assembly and a separate sectionable substructure assembly therefor comprising a rig base, a working floor mounted in spaced relation above the base and a rig base extension extending outwardly from the drawworks side of the rig base. In a preferred embodiment, rail means defining a mastway are provided between the erected working floor and the rig base extension. The base mast section of the telescoping mast assembly is provided with cooperative mast roller means whereby the base of the mast structure is readily conveyed to the working floor and whereby the drawworks side mast legs are engaged into a trunnion arrangement therefor. Means are also provided for raising of the mast structure to the vertical from the drawworks side of the rig.

Luminescent compositions, methods for making luminescent compositions and inks incorporating the same

Abstract: A particulate luminescent composition is disclosed that, when excited by electromagnetic radiation at a first frequency, emits electromagnetic radiation at a second frequency equal to or within 1500 cm'1 of the first frequency. The luminescent composition comprises substantially spherical particles having a weight average particle size of less than about 10 μm and a particle size distribution such that at least about 90 weight percent of the particles are not larger than twice the average particle size.

Polymeric compositions containing nanotubes

Abstract: A polymeric composition containing at least one polymer and carbon nanotubes is described. The polymeric composition can have carbon nanotubes that are multi-wall carbon nanotubes and/or single-wall carbon nanotubes. The compositions can also contain carbon black. Also described are various articles made from the polymeric compositions including cables and other articles
