Abstract: A system and method for the automatic and continuous high-speed measurement of color and geometry characteristics of solid shaped particles. The system includes a shaped particle feeder that sorts and aligns singularized particles and feeds them onto a means for moving the singularized shaped particles to a color inspection station and a shape inspection station. The color inspection station provides for measuring the color of each singularized shaped particle and the shape inspection station provides for measuring the geometry characteristics of each singularized shaped particle. This information is analyzed by a master computer with the statistical information displayed.

Abstract: Implementations of the disclosed subject matter provide a lubricating composition for use as a transmission fluid in an electric vehicle. The lubricating composition may include at least 70 wt %, based on the overall weight of the lubricating composition, of a biodegradable ester base oil with a kinematic viscosity at 100° C. in the range of 2.5 to 7.0 mm2/s. The ester is biodegradable according to OECD test guidelines series 301. The composition may also include at least 0.5 wt % and no more than 10 wt %, based on the overall weight of the lubricating composition, of a viscosity index improver which is at least one high viscosity ester with a kinematic viscosity at 100° C. of at least 1000 mm2/s; an anti-foam additive selected from silicone oil based antifoam additives and polyacrylate antifoam additives. Also disclosed is a process for lubricating an electric vehicle drive train comprising a transmission by applying the lubricating composition to the transmission.

Abstract: A facility for the production of liquefied natural gas comprising a liquefaction train. The train comprises a plurality of modules to perform the process steps associated with liquefied natural gas production. The train further comprises a primary cooling loop to cool at least a process stream from each module and a first and a second mixed refrigerants against a first coolant comprising clean water. The primary cooling loop is a closed clean water loop, and the cooling is against an ambient temperature. The train further comprises a first plurality of heat exchangers through which the primary cooling loop extends. The cooling is via heat exchange in at least the first plurality of heat exchangers with respect to the first coolant. More than 50% of the first plurality of heat exchangers are printed circuit heat exchangers, which are adapted to provide at least 80% of the cooling against the ambient temperature.
