Abstract: A wireless phone user registered for push-to-talk (PTT) services desires a push-to-talk session with a party on a network computer accessible via a public data network (like the Internet) that is not registered with any PTT service. The registered user enters a unique identifier, as a destination address for such computer, and a PTT server uses the unique identifier to query a Directory Service available on the public data network to obtain a PTT address for the destination computer. The PTT server then forwards or proxies the PTT request to the destination computer. As a result, the number of push-to-talk destinations available to the wireless phone user is expanded to include any number of push-to-talk enabled computers available on the Internet that are known to the Directory Service.

Abstract: An apparatus for gathering individual glass fibers into spaced apart strands is disclosed. The individual fibers, during formation are passed over an applicator which applies a lubricant to the fibers. A circular cylindrical bar member, at an oblique angle to the application surface, contacts the spaced apart strands, and in conjunction with a cylindrical free wheeling roller, causes the fibers to be consolidated into a plurality of spaced apart strands according to the natural filament split.
