Abstract: The present invention provides methods for controlling the optical properties of a light transmissive article. The method includes identifying a target window in an Abbe diagram comprising reference polymeric materials. The method further includes selecting a first polymeric material from the reference polymeric materials and compounding the first polymeric material with a stable UV chromophore to provide a first polymer composition. The method further includes transforming the first polymer composition to provide the light transmissive article, wherein the light transmissive article has an Abbe number and a refractive index which falls within the target window. Light transmissive articles prepared using the above methods are also provided.

Abstract: A viscous fluid clutch (1) for use as a clutch for a cooling fan for a vehicle, the clutch includes an input shaft (10), a rotor assembly (20, 30), a first housing portion (52), a second housing portion (42), a coil assembly (80), and a brush box (105). The rotor assembly is coupled to the input shaft. The first housing portion is coupled to the second housing portion and the second housing portion is rotatably disposed on the input shaft. The first and second housing portions define a fluid reservoir (16) for receiving the rotor assembly and a viscous fluid, preferably of the magnetorheological type. The coil assembly (80) is coupled to the first housing portion (52). The brush box is operably coupled to the coil assembly. When the coil assembly is energized by the brush box, a magnetic field is created that acts upon the magnetorheological fluid to vary the torque transfer of the input shaft to the housing and the fan connected thereto.

Abstract: A novel method of navigating the Internet is disclosed. Hyperlinks to web sites are grouped and displayed using the paradigm of shops in a town or village setting. Buildings in the town represent a collection of hyperlinks having a common theme. Buildings can be grouped together into districts representing common concepts, such as retail establishments, banks, restaurants, etc. Additionally, towns from various different cultures can be presented, having culturally localized web sites associated therewith.

Abstract: The invention provides a method of steam stripping an inorganic powder by contacting the inorganic powder with a silylating agent to form a silylated mixture which is pneumatically transported and contacted with steam to form a vaporous stream. This vaporous stream is then transported to a separation stage and the volatile materials are separated from the inorganic powder.

Abstract: An electronic device for compensating voltage fluctuations in an electrical power distribution circuit controls operation of a transformer of the type having a TCUL voltage regulator by automatically calculating the voltage bandwidth of the transformer based upon a stored value for peak current in the distribution circuit. The peak current value is automatically updated when the actual current in the circuit exceeds the stored peak current value for a predetermined sustained period of time indicating a change in overall loading patterns in the circuit but, regardless of increases in actual current in the distribution circuit, the apparatus prevents the output voltage from exceeding a preset absolute maximum.
