Title: Level monitoring using fibre-optic links
Inventor: KOUDIS STEFANOS GEORGE
IPC: G01F23/36
Filed: 1990-06-06
Abstract: A level monitoring system employing fibre-optic links 5 for level detection of flammable and non-flammable liquids. The system is built in order to eliminate the use of intrinsic safety apparatus and can be employed in areas of high electromagnetic interference and noise. A rack 3 and pinion mechanism is incorporated translating the rotational motion of the float, resulting from the varying liquid level, into a linear motion. The position of a variable optical attenuator 4 mounted on the rack 3 determines the amount of light, which is sent from a light source via fibre-optic links 5, to a light detector. <IMAGE>
Patent GB-2235588-A (GB)
Title: Antenna arrangement for a portable transceiver
Inventor: CHIN MELISSA C
IPC: H04B1/034
Filed: 1990-07-31
Abstract: An arrangement for increasing the level of radiated and received energy in a telescoping antenna 15 while the antenna is in a collapsed position. The increase in energy is obtained through use of a sliding member 22 which projects from the base of the antenna and contacts antenna matching circuitry 23, 24, 14 for making changes to this circuitry when the antenna is collapsed. Initially tuned for resonating signals for transmission and reception with the antenna in an extended position, the antenna matching circuitry is retuned by a switching action provided by the sliding member for more effective resonating of these signals with the shorter length antenna. The switching action of the sliding member may also activate gain control circuitry (Fig 6) which increases the signal levels in both an associated transmitter and receiver when the antenna is in the collapsed position. Transistors (61 and 62) are turned on in the collapsed position of the antenna to increase the gain of receiver transistor amplifier (71) and transmitter transistor power amplifier (81). <IMAGE>

Title: Compensating eddy-current effects with reversed gradients
Inventor: RATZEL DIETER
IPC: G01R33/565
Filed: 1993-02-03
Abstract: To obtain a nuclear magnetic resonance (NMR) spectrum from a measuring volume, a first data set is recorded which contains the observable measuring signals from the volume. The method is repeated in a second run with a magnetic gradient field -G with opposite polarity to the magnetic gradient field G used for the first set. The other experimental parameters of the first run are maintained. A second data set is recorded and is added to the first data set. This reduces side bands in NMR spectra and artifacts in NMR-images, caused by disturbances of the magnetic field Bo due to eddy- currents caused by gradient switching. <IMAGE>

Title: Production line control system
Inventor: MATSUDA KINJI
IPC: G05B19/418
Filed: 1994-09-13
Abstract: In a production line where a line of workpieces 1 are to be processed at a series of workstations (APU) 11, each of the workpieces 1 has identification data stored thereon 20 relating to the processing required both on that particular workpiece (NOW) and on a number of workpieces (NEXT 1, NEXT 2 etc) upstream of that particular workpiece. The data is read by sensor means (ANT) at each APU. The processing of a workpiece is only carried out when the data read from the storage means on that particular workpiece coincides with data concerning that particular workpiece carried on workpieces that have already arrived at the APU. The system provides for rewriting stored data when a workpiece is removed from the production line eg due to it being faulty. The aim is to reduce APU idle time by providing data on workpiece requirements before the workpiece arrives at the workstation. <IMAGE>
