Title: Power flow control in AC systems using directly connected rotary power converters
Inventor: GERTMAR LARS
IPC: H02K3/40
Filed: 1997-11-28
Abstract: An AC power line 2 between two parts of a medium- or high-voltage power transmission/distribution system, or between two systems, has a first rotary power converter 1 directly connected, by a transformerless connection, in shunt with the line 2, and a second rotary power converter 3 directly connected in series with the line 2. Converters 1, 3 may be synchronous machines controlled to adjust effective impedance of line 2, effective phase angle between voltages at the two ends of line 2, and line voltage magnitude. Shunt converter 1 may be operated to control active and reactive power exchange between line 2 and converter 1, and series converter 3 may be operated to control power flow through line 2. Shunt converter 1 may normally run as a motor lightly loaded by series converter 3 forming a series compensator normally running as a generator. Rotors of machines 1, 3 may be on a common shaft 6 to which are also attached auxiliary generators 7 which energise rotor windings of machines 1, 3 via static converters. Two transmission lines operating at different voltages and having respective series connected rotary converters (5, Fig.9) may be coupled to a common line via a shunt machine 1 which also acts as an autotransformer. To allow the transformerless connection of the machines, they may be wound with a cable having an inner conductor (41, Fig. 10) surrounded by inner and outer semiconducting layers (43, 44) with an intermediate insulating layer (45). Outer layer (44) is connected to ground at spaced points and acts as a static shield ensuring that the electric field of the cable is retained within the insulation 45. Insulation levels may be from 6 to 70 kV for distribution systems, and up to 800 kV or more for transmission systems.

Title: Injection system for pre-polarised fluid used in magnetic resonance (MR) measurements
Inventor: YOUNG IAN ROBERT
IPC: A61B5/055
Filed: 1998-01-27
Abstract: A patient bed 1 of an MR imaging apparatus is provided with a tube 17 through which pre-polarised fluid can be injected into a patient in order to improve contrast when imaging veins, arteries or other vessels in the body. Fluid is delivered from pump 2 into a high field polarising magnet 3 and along a tube 4 to the patient. Valve 5 is provided so that fluid in the tube 4 downstream of the pre-polarised fluid can be discarded rather than being injected in the patient, and is associated with a reservoir into which the fluid to be discarded and the pre-polarised fluid can be rapidly injected. Then, when the pre-polarised fluid is injected into the patient, its magnetisation has not deteriorated by as much as it would have done if the tube 4 had been directly connected into the patient.

Title: Combined spacecraft propulsion and thermal control system
Inventor: BASUTHAKUR SIBNATH
IPC: B64G1/40
Filed: 1998-04-15
Abstract: A spacecraft has combined propulsion and active thermal control systems. A propellant storage tank (20, fig 1) is coupled to a pressurant storage tank 18. A working fluid 52 resides in the pressurant storage tank 18 and propels propellant when needed while concurrently acting as a thermal working fluid.

These components may include a thermal radiator panel 44 to transfer excess heat to space. A controller 36 monitors temperature sensors 88 and controls valve assemblies 60, 78 to determine the components 64, 82 to which the working fluid 52 is routed. A component may be both a cooled component and a heated component.

Patent GB-2329805-A (GB)
Title: Read error recovery utilizing ECC and read channel quality indicators
Inventor: GENHEIMER STEPHEN REEVES
IPC: H03M13/00
Filed: 1997-03-27
Abstract: An apparatus and method for recovering from read errors detected by a read channel (70) in a sequence of data read from a disc (18) of a disk drive (10) by using read channel quality indicators to determine the appropriateness of using error correction in combination with other corrective actions utilized in the recovery process. Upon the detection of an uncorrected error in the retrieved data, the disk drive (10) enters a read recovery routine wherein one or more corrective actions (102, 122) are applied in an effort to resolve the error. One of the channel quality indicators comprises a channel quality measurements (108,128) determined as the sum of the square of the sampled data bit error values recovered during the read operation. When the channel quality measurement is at or below a threshold value indicative that the probability of passing undetected erroneous data is at an acceptable level (110, 130), error correction is applied to the data (112, 138); otherwise, error correction is disallowed (118, 140). Additional channel quality indicators comprise erasure pointers (132) which identify a particular set of symbols that are suspected of containing a read error.

The means 103 analyzes the 2nd byte of the expanded instructions. A return address setting means 104 decides the instruction length of the expanded instructions and sets up the leading address of the instruction next to the expanded instructions on the objective program as a return address and an expanded instruction executing means 105 executes the expanded instructions analyzed by the means 103.
