Abstract: The present invention provides for oxygen scavenging materials and uses thereof for reducing oxygen content in an air cavity of a mounted tire, such as to reduce oxidation of a tire. The oxygen scavenging material can include a metal or metal-based material, an antioxidant, or microorganism. In one example, the oxygen scavenging material may be situated or secured within a tire cavity or secured to the tire rim of a wheel prior to mounting of the tire on the rim. Accordingly, the tire is mounted on the tire rim to define an air cavity with the oxygen scavenging material being located therein. The air cavity is be filled with air comprising oxygen to a desired internal air pressure with the oxygen scavenging material being provided in an amount sufficient for reducing oxygen content in the air cavity, such as to reduce oxidation of the tire thereby increasing the lifespan thereof.

Abstract: A packet switch router that processes downstream digital information to provide dedicated bandwidth to each subscriber destination on a hybrid fiber coax (HFC) network. The router includes a network module that terminates a network connection, a switch that forwards data from the network module, and a channel module. The channel module includes a switch interface, a cell processing engine, one or more modulators, and a radio frequency (RF) transmitter network. The switch interface forwards packetized data from the switch to the cell processing engine. The cell processing engine organizes the packetized data into multiple data streams, encapsulates data in each stream into data cells, and multiplexes the data cells into a multiplexed cell stream. Each modulator is configured to modulate a multiplexed cell stream into an analog signal. The RF transmitter network up converts and combines a plurality of analog signals into a combined electrical signal for transmission.

Abstract: The process of this invention can be utilized to stabilize tin-coupled rubbery polymers. It is particularly useful for stabilizing rubbery polymers that do not contain bound styrene. This invention more specifically discloses a process for improving the stability of a tin-coupled rubbery polymer which comprises (1) adding 0.1 phr to about 4 phr of styrene to a living rubbery polymer to produce a styrene capped rubbery polymer, (2) adding a tin halide to the styrene capped living rubbery polymer to produce the tin-coupled rubbery polymer, and (3) optionally, adding a tertiary chelating alkyl 1,2-ethylene diamine or a metal salt of a cyclic alcohol to the tin-coupled rubbery polymer. The use of metal salts of cyclic alcohols is preferred because they do not lead to recycle stream contamination. This is because cyclic alcohols do not co-distill with hexane or form compounds during steam-stripping which co-distill with hexane.
