Title: Charging in a telecommunications system
Inventor: TOIVANEN KYOSTI
IPC: H04M15/00
Filed: 1999-08-16
Abstract: A method of charging at a mobile switching centre, MSC (5) of a mobile telecommunications network (2) in respect of a call initiated by a mobile terminal (1;1 registered with the network (2) and germinating outside of the network. At the MSC (5) the call is classified, according to the associated A-number and/or the B-number, as corresponding either to a call for which the MSC (5) is to be the charge determination point or to a call for which the charge determination point is located outside of the mobile telecommunications network (2). In the event that the call belongs to the latter class, the MSC (5) receives tariff information from the external charge determination point (7, 9) and calculates charge information on the basis of the received tariff information. In the event that the call belongs to the former class, the MSC (5) disregards any tariff information received from an external charge determination point and calculates charge information on the basis of the mobile telecommunications network's own tariff information.

Title: Contortrostatin (cn) and methods for its use in preventing metastasis and other conditions
Inventor: MARKLAND FRANCIS S JR
IPC: A61K38/17
Filed: 1999-09-29
Abstract: The amino acid sequence of native contortrostatin was used in a cloning strategy to obtain full-length cDNA and deduced amino acid sequnces for a contortrostatin precursor. The precursor includes pro-protein, metalloproteinase, and disintegrin (contortrostatin) regions of the multidomain protein. The sequences can be used to produce recombinant DNA molecules which code on expression for contortrostatin proteins, including biologically active variants and fragments.

Title: Flat minibands with spatially symmetric wavefunctions in intersubband superlattice light emitters
Inventor: CHU SUNG-NEE GEORGE
IPC: H01S5/34
Filed: 2001-05-22
Abstract: The RT regions of an ISB light emitter comprise pre-biased SLs and a multiplicity of split quantum wells (SPQWs). A SPQW is a quantum well that is divided into a multiplicity of sub-wells by a first barrier layer sufficiently thin that the upper and lower energy states are split beyond their natural broadening and contribute to different minibands in each RT region. In contrast, adjacent SPQWs are coupled to one another by second barrier layers. The thicknesses of the latter layers are chosen so that minibands are created across each RT region. In one embodiment, the emitter includes an I/R region between adjacent RT regions, and in another embodiment the I/R  regions are omitted.

Title: Split flow process and apparatus
Inventor: MARIZ CARL
IPC: B01D53/14
Filed: 1999-11-22
Abstract: A recovery plant for recovery of a gaseous component, such as carbon dioxide, from a process gas, such as the exhaust from a combustion turbine, has an absorber (110) employing a lean solvent (126) in an upper section of the absorber and a semi-lean solvent (172) in a lower section of the absorber. A regenerator (120) extracts the gaseous component from the rich solvent (117) thereby producing a regenerated lean solvent (126) and a semi-lean solvent (127). A solvent flow control element (170) combines at least a part of the semi-rich solvent (118) from the upper section of the absorber with the semi-lean solvent (127) from the regenerator to form a mixed solvent (171), and a cooler (112) cools the mixed solvent that is subsequently fed into the lower section of the absorber (110). By cooling the mixed solvent prior to entry into the absorber, the thermal energy required to remove the carbon dioxide from the exhaust gas can be reduced.

Inventor: MOON JAMES E
IPC: H01L21/302
Filed: 2000-06-14
Abstract: Three fundamental and three derived aspects of the present invention are disclosed. The three fundamental aspects each disclose a process sequence that may be integrated in a full process. The first aspect, designated as "latent masking", defines a mask in a persistent material like silicon oxide that is held abeyant after definition while intervening processing operations are performed. The laten oxide pattern is then used to mask an etch. The second aspect, designated as "<u>s</u>imultaneous <u>m</u>ult<u>i</u>-<u>l</u>evel <u>e</u>tching (SMILE)", provides a process sequence wherein a first pattern may be given an advanced start relative to a second pattern in etching into an underlying material, such that the first pattern may be etched deeper, shallower, or to the same depth as the second pattern. The third aspect, designated as "delayed LOCOS", provides a means of defining a contact hole pattern at one stage of a process, then using the defined pattern at a later stage to open the contact holes. The fourth aspect provides a process sequence that incorporates all three fundamental aspects to fabricate an integrated liquid chromatography (LC)/electrospray ionization (ESI) device. The fifth aspect provides a process sequence that incorporates two of the fundamental aspects to fabricate an ESI device. The sixth aspect provides a process sequence that incorporates two of the fundamental aspects to fabricate an LC  device. The process improvements described provide increased manufacturing yield and design latitude in comparison to previously disclosed methods of fabrication.
