Title: Symmetric dispersion-managed fiber-optic cable and a fiber-optic transmission system
IPC: G02B6/34
Filed: 1997-02-14
Abstract: A symmetric, dispersion-managed fiber optic cable in accordance with the present invention includes a first and a second optical fiber. The first optical fiber is a conventional single mode fiber (SMF) type fiber and has a first effective area and a positive dispersion characteristic at a predetermined operating wavelength range. The first optical fiber is split into two segments each having substantially the same length. The second optical fiber has a second effective area and a negative dispersion characteristic at the operating wavelength range. Typically, second optical fiber is a DSF or an NZD fiber, both with negative dispersion and a small effective area. The second optical fiber is coupled between the two segments of the first fiber to create a fiber optic cable with an average total dispersion at the operating wavelength range which is substantially zero. The fiber optic cable may be incorporated into an optical fiber transmission system with an optical terminal and at least one repeater.

Title: Method of running olefin epoxidation plant (options)
Inventor: DZHABIN DZHON K ML
IPC: C07D301/14
Filed: 1998-09-23
Granted: 2003-05-27
Abstract: FIELD: industrial organic synthesis. SUBSTANCE: epoxidation of olefin is carried out on several in series connected capacitive reactors, each of which contains fixed heterogeneous catalyst bed, for instance silica-supported titanium dioxide. When catalyst activity in any of reactors lowers to unacceptable level, this reactor is brought out of the process and an additional reactor containing fresh or regenerated catalyst is brought in. Indicated reactor, according to different embodiments of the process, can be included into succession of reactors as the first or the latter one. For example, inlet stream can be first brought into contact either with most active or with least active portion of catalyst in reactor succession. Whereas the last option allows increasing to some extent life time of catalyst, the first one requires considerably lower productivity of heat- exchangers. EFFECT: essentially reduced consumption of catalyst compared to conventional fixed catalyst-bed epoxidation processes wherein all amount of catalyst is replaced or regenerated simultaneously. 26 cl, 2 dwg, 4 tbl, 2 ex
