Title: Method and apparatus for introducing controlled spin in optical fibers
Inventor: HAWK ROBERT M
IPC: C03B37/027
Filed: 1997-07-03
Abstract: Optical fiber is provided with a periodically reversing spin while the fiber is pulled through a melt zone. A cooled region of the fiber downstream fro m the melt zone passes between a pair of opposed elements. The opposed elements are moved so that surface regions engaging the fiber move in opposite lateral directions relative to one another, thus spinning the fiber about its ax is. The lateral movement of the engaged surface portions is periodically reversed to reverse the spin direction. The opposed elements may include belts or rollers, which can be tilted to orientations oblique to the longitudinal direction of the fiber.

Title: Automatic updating of a local database supporting local number portability
Inventor: BHAGAT PROMOD KUMAR
IPC: H04M15/08
Filed: 1998-01-30
Abstract: In accordance with the teachings of a prior application, in a telecommunicationsnetwork, a local database stores destination telephone number information derived from a more global database, shared by a plurality of switching systems usually remote from all or most of the systems. One or more bit maps are used to store key indicators for each telephone number for which information may be required. Thisinvention relates to a method and apparatus for automatically updating the localdatabase, by recognizing that a switch identified as serving a directory number does not have access to the line corresponding to that number; when this condition isdiscovered, the global database is increased and the local database updated.

Title: Improved back-up power tongs
Inventor: BUCK DAVID A
IPC: B25B5/14
Filed: 1996-10-11
Abstract: The present invention provides back-up power tongs (1) for holding a tubular member (2) against rotation of a connected tubular member. The back-up power tongs comprise a body (3) with a front section for receiving the tubular member and a plurality of jaw members (5, 7) for engaging the tubular member.  The jaw members are positioned to form a substantially closed perimeter around the tubular member and at least one of the jaw members is a pivotal jaw (7), moving in a pivotal path to engage the tubular member. An alternate embodiment provides two pivoting jaws (107a, 107b) and a locking mechanism (100) attached to the end of the pivoting jaws such that the pivoting jaws can be securely interlocked. The improved back-up tongs should not require the tong body to virtually enclose the pipe and thus will allow the improved back-up tongs to be considerably smaller.

Filed: 1998-04-07
Abstract: An integrated heat-exchanging forming tool is prepared from a pre-formed metallic shell having an outer contoured shaping surface corresponding in configuration to the shape to be imparted to an article of manufacture to be formed by the tool. The shell is backed by a porous metallic support body comprised of a plurality of discrete metallic elements that have been heated and bonded metallurgically to each other and to the backside surface of the shell while providing a network of interconnected pores or channels throughout the body through which a heat transferring fluid may be circulated for transferring heat to or from the shaping surface of the shell and provide a structurally rugged mold capable of withstanding high molding pressures.                The primary/fundamental concept of mold design and construction is fulfilled, namely design and construct one piece molds having an open, internal structure beneath the molding surface thus providing for a uniform and short path for thermal energy flowing from the molded part to the heat transfer fluid; a 10-15 fold increase over non-porous molds in the surface area of the fluid side contact with the heat transfer fluid; turbulent flow of the heat transfer fluid at all normal flow rates, and structures which will handle up to 10, 000 psi in compression.

Abstract: A texture compositing apparatus (figure 6) and method for combining multiple  independent texture colors in a variety of ways in a single execution pass using a single texture compositing unit (TCU) (304) per texture. The TCU (30 4) receives a control signal, (216) a blend factor (320), a local data signal (Clocal/Alocal) (226C, 228C), and an output data signal (Cin/Ain) (218B, 220 B) generated by another TCU, the local data signal and the ouput data signal represent a texture color in a RGBA format. Based upon the control signal (216), the TCU (304) can generate an output signal (218C, 220C) based on a variety of functions. The outputs that can be generated include but are not limited to: (1) zero; (2) one; (3) Cin; (4) Clocal; (5) Cin + Clocal; (6) Ci n -  Clocal; (7) Cin * Clocal; (8) Cin * Clocal + Alocal; (9) Cin * Alocal + Clocal; (10) (Cin - Clocal) * Fblend + Clocal; and (11) (Cin - Clocal) * (1- Fblend) + Clocal.

Title: System and method for performing on-line reviews and approvals of credit and liability applications
Inventor: SEIB DENNIS
IPC: G06Q40/00
Filed: 1996-12-12
Abstract: An on-line computerized system that operates in real-time to process applications for products and services offered by a financial institution. The system automates the credit and liability review and approval process, performs background credit worthiness evaluations based on applicant's (10) credit score (28), financial information and new or existing relationship with the financial institution (52), recommends to those applicants (10) that exceed the initial criteria for credit consideration specific credit products with predetermined credit qualified offer amounts. The system immediately analyzes an applicant's (10) credit bureau history (30, 32, 34) and automated credit scoring (28), and provides these results to the LBR (12). The system can supply applicants with up-front conditional approval (based on systematic evaluation of credit bureau history, credit score, debt burden, and applicant's new or existing relationship deposits), subject to required verifications. The invention can also identify and communicate to the LBR (12) other services/products which the applicant may be credit worthy but has not requested. The LBR (12) can then offer a package of products, enhancements (tier pricing) and services to the applicant rather than simply the one requested. For those applicants (10) that exceed credit criteria, the system recommends specific credit products with predetermined credit qualified offer amounts. Processing may be interrupted and continued for the same applicant at a later point with the same or different LBR (12).
