Title: A security device
Inventor: DAY STEPHEN
IPC: B60R25/042
Filed: 1993-07-24
Abstract: The device has an armature 4 and a first coil 6, which is inductively coupled to a second coil 8. The armature 4 is movable to block or unblock the passage of fluid in a pipe. The second coil 8 is connected to a power supply which provides a continuously varying voltage when a key is operated so that it induces a current and magnetic field in the first coil 6. The magnetic field in the first coil 6 causes the armature 4 to move. A DC field applied to the second coil 8 does not move the armature 4.

Title: Depth related special video effects
Inventor: NAKATA TETSURO
IPC: H04N5/262
Filed: 1994-03-29
Abstract: A foreground video signal SV is mixed with a background video signal SB in mixer 18 using a key signal SK and depth data Z to produce a dimming effect; the greater its distance Z, the lower the dimmer the foreground image appears. To prevent complete merging of the foreground image with the background image the foreground video signal SV is reduced is mixed 14 with a matte signal SM using a depth dependent key signal GZ varying from 1 to 0 so that at great depths only the matt signal is output as the dimmed foreground video signal. A similar process may take place with the key signal SK in mixer 17 to provide a fading effect in which the foreground video signal is not completely faded. Changeover switch 12 may be provided to select which effect is to be produced, or if omitted simultaneous dimming and fading may take place. <IMAGE>

Title: Battery charger for portable radio telephone
Inventor: MCKILLOP WILLIAM ANTHONY MITCH
IPC: H02J7/00
Filed: 1994-07-08
Abstract: A charge pump circuit 52 - 57 is used to provide a voltage boosting action so that the battery (32, Fig. 4) of the radio telephone can be charged from a vehicle supply (33) of substantially the same nominal voltage as the battery (32). A 70Hz oscillator 52 causes a capacitor 57 to be alternately charged from the vehicle supply (33) and discharged in series with that supply through the battery (32). Interference with the telephone transceiver (31) is minimised by driving the charge pump with a low frequency oscillator 52 and by use of constant-current capacitor charge 55 and discharge 54 circuits. A relay (45, Fig. 4; 61, Fig. 6) operated by a voltage detector (43) causes the transceiver (31) to be powered from the vehicle supply (33) when present or from the battery (32) in the absence of vehicle power. A voltage holdup capacitor (87, Fig. 6) maintains current to the transceiver (31) while the relay switches. <IMAGE>

Title: Fluid channelling member for use in heat transfer tubes
Inventor: MARSHALL GRAEME DONALD
IPC: F28F13/12
Filed: 1994-07-22
Abstract: A heat transfer device 12 has a tubular casing 14 and a member 16 located in the tube 14. The member 16 is elongate and has radial walls 20 on a central spine 22. The walls 20 are helical to define helical channels 18 along the whole length of the member 16. Lips 26 on each wall increase the surface area for heat transfer. In use, warm fluid passes along the helical paths, to be continually in motion around the spine 16, and coolant passes around the device 12. This makes different portions of the warm fluid come into contact with the tube 14. The member 16 may be made of aluminium which is twisted after extrusion. The member is preferably an interference fit in the tubular casing which may be made of copper. <IMAGE>

Title: Antenna tracking
Inventor: EGUCHI KOUICHI
IPC: H01Q1/27
Filed: 1995-07-24
Abstract: In order to track a navigation satellite, an antenna array (10, fig 1A) mounted on a turntable (12) switches its beam between two directions (fig 2) using phase shifters (24). In an initial search mode, the antenna is rotated and the satellite is located when the outputs from the two beams is equal. For subsequent control of the antenna direction in a tracking mode, a second signal is obtained from an angular motion (rate) sensor 20 whose output is offset, high-pass-filtered 48 and combined with a tracking error signal derived from the antenna outputs; the control operates to reduce this combined signal to zero. This combination allows tracking to continue even when no reliable signal is received and the antenna is mounted on a moving platform such as a ship. Two-dimensional tracking is similar (fig 6, 7). <IMAGE>

Title: Combustion misfire sensing method
Inventor: MEZGER MANFRED DIPL ING
IPC: F02D45/00
Filed: 1996-07-31
Abstract: A method of sensing combustion misfires in an internal combustion engine operates on the basis of a first signal ts(n) in which the unevenness of the rotational movement of the crank shaft of the engine is indicated, and a second signal * small Greek phi *(n) which is periodic and of which the period duration corresponds to the period duration of an operating cycle of the engine or to this period duration divided by a whole number, and which second signal comprises a fixed phase relationship to the rotational movement of the crank shaft. The second signal is modulated and filtered with a signal based on the first signal to produce a modulated third signal q(n) which is used to sense combustion misfires and to identify the cylinder concerned. As described the first signal is modified in a block 4.3 to remove the effects of sensor wheel inaccuracies and in a block 4.4 to remove the effects of engine speed change, prior to modulation block 4.5 and filter block 4.6. The method is stated to be applicable to engines with a large number of cylinders, and operable at high engine speeds and low loads.

Title: Sub-sea pipeline span detection system
Inventor: PITCHFORD JOHN
IPC: G01M5/00
Filed: 1996-08-08
Abstract: A sub-sea pipeline span detection system comprises an inspection vehicle (a pig) that passes through a sub-sea pipeline, e.g. driven by the flow of fluid, and identifies sections of that pipeline which are exposed from the sediments and which span between sections of the sea bed. The system detects changes in the resilience of the pipeline by monitoring the relative positions of a rotary or oscillatory mass 6 and its supporting body which is itself supported in the pipeline by sprung riders 3. As shown the mass 6 is an out-of-balance mass driven in rotation by a motor 4 via a shaft 5, causing a head 7 to whirl within the pipeline. The motion of the head depends upon the stiffness of the pipeline and thus on whether the pipeline is exposed or buried. The phase angle between the rotating mass 6 and the head 7 may be used as an indication of the pipeline stiffness.
