  • Process for making polyol neoalkylester plasticizers from neo acids
    Patent number: 8568846
    Abstract: Provided are compositions, processes for making, and processes for using neoalkyl polyol esters and triglycerides as plasticizers. In one form, a neoalkylester triglyceride plasticizers can be produced by (i) drying a polyol feedstream; (ii) contacting in a reactor the dried polyol feedstream with a neoacid feedstream under effective temperature, pressure and time to form a neoalkylester plasticizer effluent stream, and (iii) purifying the neoalkylester plasticizer effluent stream to remove unreacted polyol and unreacted neoacid to form a neoalkylester plasticizer. Such plasticizers can be phthalate-free and provide outstanding properties including a suitable melting or pour point, glass transition temperature, low volatility, increased compatibility, increased hydrolytic stability, and excellent low temperature properties in a range of polymeric resins.

  • TORQUE-LIMITING NUT ASSEMBLY
    Publication number: 20120237312
    Abstract: A torque-limiting nut assembly, in a preferred form, includes an inner nut engaged with a shaft. A resilient torque member and a rigid torque member are positioned between the inner nut and an outer nut, with each being rotatably fixed to one of the nuts. Rotating the outer nut relative to the inner nut compresses the resilient torque member with the rigid torque member, moving the nuts along the shaft in a first axial direction until the resilient torque member is compressed out of engagement with the rigid torque member. Rotating the outer nut in the opposite direction engages the resilient and rigid torque members thereby urging the nuts in the opposite direction. The torque-limiting nut assembly provides a convenient device to apply the correct amount of application-specific torque.

  • Methods and apparatus for providing synchronization in a multi-channel communication system
    Patent number: 7860044
    Abstract: A multi-channel processing module is arranged in series with multiple channels of a communication system. The processing module synchronizes downstream symbols among the channels, and synchronizes downstream symbols for at least a given one of the channels with upstream symbols for that channel. The synchronization of downstream symbols among the channels and the synchronization of downstream symbols for at least the given channel with upstream symbols for that channel are collectively achieved by adjusting downstream and upstream adjustable delay elements associated with respective downlink and uplink signal paths in the multi-channel processing module. The channels may comprise respective subscriber lines of a DSL communication system.

  • Method and apparatus for selectively terminating current in a digital subscriber line (DSL) modem
    Patent number: 7676031
    Abstract: A method and apparatus for selectively terminating sealing current in an asymmetric digital subscriber line modem is provided. The technique comprises providing a mechanism (e.g., a resistor or suitable current sink) to a DSL modem (e.g. an ADSL modem or any XDSL modem used where POTS is underlying service). The mechanism is operable to be dynamically switched on and off and to operate under low current conditions. The system allows for provision of DSL (e.g., ADSL or XDSL where POTS is the underlying current) in the absence of plain old telephone service (POTS) and for improved performance.
