Title: Separating a multi-component feed stream using distillation and a controlled freezing zone
Inventor: POTTS JR WILLIAM A
IPC: F25J3/02
Filed: 1992-02-27
Abstract: For separating two primary components of a multi-component feed stream (e.g., methane and nitrogen) in the presence of a third, freezable component (e.g., carbon dioxide) having a relative volatility less than that of either primary component, at least a lower distillation section 106 and a controlled freezing zone ("CFZ" - 108) are employed. In one arrangement, the freezable component is frozen in the CFZ, and the resulting solids are collected at the bottom of the CFZ. The CFZ also produces a vapor overhead product enriched in one of the primary components and a liquid bottom product enriched in the other primary component. The solids of the freezable component are melted and mixed with the CFZ liquid bottom product to form a liquid feed stream for the distillation section which operates like a conventional distillation section, while tolerating significantly high concentrations (i.e., >0.1 mole %) of the freezable component without solids formation, at temperatures well below the freezable component's freezing point. <IMAGE>

Title: Assay for autoantibodies against thyroglobulin or thyroid peroxidase
Inventor: PETERSEN VAUGHAN BRYCE
IPC: C07K16/40
Filed: 1992-05-16
Abstract: Lymphocytes are extracted from thyroid tissue of an individual with anti-Tg or anti-TPO positive serum, purified and fused with mouse myeloma cells (e.g. cell line X63 - Ag. 8) using polyethylene glycol. The resulting cells are cultured in the presence of HAT medium to select for hybrids. The hybrids are screened for anti-Tg or anti-TPO autoantibodies. Hybridomas secreting such antibodies are cultured to obtain monoclonal autoantibody. The monoclonal autoantibodies are used in competitive assays for anti-Tg or anti-TPO autoantibodies in samples taken from patients. The antibodies may also be used as a basis for preparing nucleotide probes useful in the study of autoimmune disease involving the production of anti-Tg or anti-TPO antibodies.

Title: Silyl-ether initiators
Inventor: SHEPHERD NEIL
IPC: C07F7/18
Filed: 1993-11-03
Abstract: This invention relates to a composition in a non-polar solvent of a monofunctional silyl ether initiator which is useful in a process for anionically polymerising a conjugated 1,3-diene monomer. The silyl ether initiator has the general formula R<1>R<2>R<3>Si-O-A-B where R<1> to R<3> are independently selected from saturated and unsaturated aliphatic and aromatic radicals, A is a short chain hydrocarbon bridging group and B is an alkali metal, usually lithium. The initiator composition is conveniently made by the process of reacting, in a non-polar solvent, an excess of an alkali metal with an organosiloxyhalide of the general formula R<1>R<2>R<3>Si-O-A-Z where Z is a halogen, the inorganic by-products being readily filtered off from the organic solution of the initiator. The non-polar solvent is hexane.

Title: Transmitting sensor data down a downhole sensor though wires supplying power to a downhole device
Inventor: VENERUSO ANTHONY
IPC: E21B47/12
Filed: 1994-07-22
Abstract: An electric cable 18 supplies power to downhole pump motor 16, 17 and also carries data from sensors in measurement sonde 20 to the well head. In order to isolate the data from the power supply (which may be 2.4 kV) inductive couplers are used both downhole to couple the sensor data to cable 18 and at the wellhead to couple 25 data to receiver 26 where it may be displayed or transmitted to a remote location. The power supply may be three-phase; in this case inductive coupling (24A, B, C figure 4) is made to each phase of cable 18 in such a way that no current is induced in the sonde by current flowing in the cable when the electrical system is in equilibrium. <IMAGE>

Title: User interaction procedure in an Intelligent Network
Inventor: JELLEMA BART
IPC: H04M3/487
Filed: 1996-07-19
Abstract: When a service switching point (SSP 14, Fig. 1) intercepts a call from an end user (12) in an intelligent network, the switching point (14) queries a service control point (SCP 16) for instructions on how to deal with the call, the control point (16) transmits instructions to the switching point (14) to initiate a multistage user interaction procedure, and the control point (16) also instructs the switching point (14) to send reports to the control point (16) at intermediate stages during the user interaction procedure. The control point is thus able to take account of the latest status of the user interaction procedure in making further decisions. When the user interaction procedure involves the switching point playing an announcement 28 to the user and collecting digits 36 from the user in response to the announcement, then in addition to the usual report sent from the switching point to the control point at the end of the user interaction procedure 38, the switching point may also report to the control point at the start and at the end of the announcement 30, 34. Decisions made by the control point may include the control point starting charging when the start of the announcement is reported.
