Abstract: A UV-resistant coating composition for protecting polyurethane surfaces, especially in a marine environment above the sea-air interface (so-called “splash zone”), is formed from an amorphous hydrophobic dimer fatty acid-based polyether polyol and an aliphatic isocyanate, such as hexamethylene diisocyanate, and may include a UV blocking agent such as titanium dioxide. The polyol may be modified with a chain extender. The composition provides an elastomeric protective barrier against the deleterious effects of UV exposure, and is useful on polyurethane surfaces on bend stiffeners, buoys etc.

Abstract: Systems, methods, and software for determining proximity to a utility and using the location information of the utility are provided herein. In one example, a non-transitory computer readable medium having stored thereon program instructions executable by a computing device is presented. When executed by the computing device, the program instructions direct the computing device to receive an indication of location of a utility, receive location information of a device, determine utility proximity information, and provide an indication of utility proximity information. The utility location information may then be used with map and other information, or used to control grading operations.

Abstract: A dispersing agent comprising the salt of a tertiary amine containing at least one poly(lower alkyleneoxy) chain and an aromatic acid having at least two benzene rings and a dispersion of an organic pigment, an organic dyestuff or carbon black in a polar organic solvent containing said dispersing agent is disclosed.

Abstract: A dispersion of a particulate solid in a polar organic medium in the presence of a dispersing agent which is a tertiary amine or a salt thereof with a mineral acid or an aromatic carboxylic or sulphonic acid, the amine containing at least one polymeric group which is a poly(lower alkylene oxy) chain or a poly(carbonyl lower alkylene oxy) chain and inks, paints and similar formulations made from such a dispersion.
