Title: Measurement of a ship's magnetic field
Inventor: COMAN A E J
IPC: G01R33/00
Filed: 1989-05-30
Abstract: Correct degaussing of a ship depends on a knowledge of the ratio of permanent to induced magnetisation and this, instead of as is usual being determined by magnetic ranging at different magnetic latitudes, is determined by mounting a single axis vertical field magnetometer (41) at the masthead (40) and measuring the field strength whilst sailing the ship on northerly, southerly, easterly and westerly courses respectively. Simultaneously with the magnetic field measurements the roll stabilisation system of the ship is used to drive the ship into a rolling mode when roll angles  phi  are measured by means of the ship's navigation system. A data logger is used to simultaneously record the magnetic field measurements and the roll motion and these measurements are then correlated. From the correlation the induced and permanent field components can be deduced. <IMAGE>

Title: Stress-reduction in power cable joint.
Inventor: GILBERT PETER RONALD
IPC: H02G15/103
Filed: 1992-08-12
Abstract: A joint between insulated conductors (3) of two electric power cables (1) incorporating insulation screens (7) is made by a method wherein after electrically connecting the ends of the conductors of the cables, the ends of the connected conductors are surrounded by a sleeve (11) of solid electrically insulating material having along its internal surface an insert (19) of a material which is substantially more electrically conductive than the sleeve and electrically contacts the connected conductors. The sleeve is positioned so that its ends project over the cable insulation (5) to provide an annular gap (17) between sleeve (11) and insulation, and the cable insulation screens are joined by a tubular electrically conducting surface (13, 23) surrounding the sleeve. The joint is completed by introducing into the joint a material in a sufficiently fluid state to penetrate and fill the annular gaps between the sleeve and cable insulation. Material between the sleeve and the cables provides respective tubular paths (15) each extending between a respective end of the insert and the corresponding end of the tubular surface which joins the cable insulation screens and having an impedance which reduces with increasing electrical stress. The method is tolerant of cable size and shape. <IMAGE>

Title: Misfire-detecting system for internal combustion engines
Inventor: HISAKI TAKASHI
IPC: G01M15/04
Filed: 1992-12-24
Abstract: In an internal combustion engine wherein the sparking voltage V is compared (Figure 3) with a reference value Vmis1 to determine whether a misfire has occurred, an abnormality detection arrangement (Figure 9) determines whether the detecting system is abnormal when it is determined (566) that no misfire has occurred for a predetermined time while fuel supply is being interrupted. Abnormality detection may be suppressed until a set time after fuel cut has started. Misfire may be detected (Figure 3) by determining whether the degree (area S2 + S3) to which the sparking voltage exceeds the reference Vmis1 exceeds a further reference, or (Figure 5 not shown) whether the sparking voltage exceeds a reference derived from a peak holding circuit. <IMAGE>

Title: Adaptive channel allocation in radio telephone communications system
Inventor: ERIKSSON HAKAN OLOV
IPC: H04B7/005
Filed: 1993-04-16
Abstract: The channels accessible to the base stations for establishing connections with mobiles are ranked in at least one priority list based on transmission loss intervals. Each channel is ranked in the priority list according to its success at previous connections and a channel allocated from high in the list which satisfies a predefined quality criterion. The amount of power required for a channel can be set lower thereby reducing the interference associated with the channel and increasing system capacity. A self planned system evolves where channels are allocated for connections based on their past connection history. Thus, the selection of channels which may interfere with calls in neighboring cells or which may suffer substantial interference from a neighboring base is avoided. <IMAGE>
