Patent GB-2267662-A (GB)
Title: Method and apparatus for treating diesel exhaust gas to remove fine particulate matter
Inventor: MILLER JOHN W
IPC: F01N13/02
Filed: 1993-08-18
Abstract: An emissions control system for reducing particulates from exhaust gases from a diesel engine includes dual catalyzed diesel particulate filters in joint communication with the exhaust stream and a pair of heater elements each associated with one of the filters, through which exhaust gas is transmitted and uniformly heated. According to predetermined alternating heating sequence, the exhaust gas stream through first one of the pair of filters and then through the other is heated. The differing pressure differentials across the filters, determined by the heating sequence, effectively shift the major portion of the flow of exhaust gas between the filters, so that over the alternating heating sequence the heat generated by the heating elements is sufficient to clean the filters, without the requirement for any auxiliary source of combustion air or any mechanical switching means. <IMAGE>

Abstract: A navigation system for motor vehicles comprises road map display means M1, map route data storage means M2, position detecting means M3 and display control means M4 for controlling the display means M1 so as to display the road map to indicate the route to be taken and the current position. Zoning means M5 (Fig 8) determine, according to the route and the position of the vehicle, a next intersection Pi on the route to be taken, and according to the course of the vehicle as it approaches Pi, also determined a plurality of sector-shaped guidance zones SH, SM, SL defined by sectors of co-axial circles CH, CM, CL having the next intersection Pi at their common centre and having different radii. One zone is selected according to the current velocity of the vehicle, such that the higher the vehicle velocity, the larger the radius of the circle corresponding to the selected zone. The driver is then informed that the vehicle is approaching the intersection Pi, and further informed of the direction to take at the intersection. <IMAGE>

Title: Method and apparatus for reading tachograph charts
Inventor: WEST PHILIP CYRIL
IPC: G07C5/00
Filed: 1992-10-12
Abstract: Method and apparatus for reading tachograph discs employs a document scanner feeding data to a personal computer and associated printer. Analysis of electronic data from the scanner enables first the establishment of the disc type and orientation, followed by identification of the data traces and analysis of these by reference to concentric bands of the disc which are converted from circular to linear form, and by a line-following process, as part of the data-processing method. Activities and violations of international vehicle regulations can be identified by counting the crossing points of the graphic trace with respect to predetermined traces representing vehicle use parameters such as speed. The computer produces a graphic display or printed summary of the data or image from the disc. <IMAGE>

Title: Device to allow complete use of drinks supplied in containers under pressure
Inventor: MORENO BARBOSA FRANCISCO
IPC: B67D1/12
Filed: 1994-06-09
Abstract: The device comprises a preferably transparent container 2 having an inlet 8 e.g. for beer and an outlet 22. A knob 11 operates an inlet valve (not shown) in the container cap 5 and an axially movable rod 10 having a resilient stop 15 at its lower end. A float 13 having a tube 14 extending therefrom is mounted over the rod 10 between the stop 15 and a depending inlet projection 9. With the rod 10 and stop 15 in a raised position, the inlet projection 9 seats in the top of the float 13 to connect with the tube 14. A forked element is pivoted on the cap 5 for movement by the float 13 to open and close a needle valve 16 leading to an acoustic alarm or whistle 19. When the knob is depressed, the cap valve is opened, allowing beer into the container 2 through the inlet projection 9 and tube 14. If the float 13 falls, foam and or gas may escape into the container 2 between the float 13 and the inlet projection 9. Simultaneously the needle valve 16 is opened to allow gas in the container 2 to operate the acoustic alarm 19. <IMAGE>

Title: Coding and decoding video signals
Inventor: WELSH WILLIAM JOHN
IPC: H04N7/26
Filed: 1993-06-29
Abstract: Video signals are coded (102) at a first relatively low frame rate. One or more portions of the image area, for example the mouth of a person speaker; recognised by feature extractor (106), are coded (110) at a higher frame rate. Preferably the second coding operates by resolving the pixel values of the image pertion - considered as a vector - relative to a set of orthogonal reference vectors (stored in 112) to produce coefficients which are then transmitted. Preferably, the feature extractor (106) normalises the image portion as regards scaling, position and rotation and sends data on these parameters as side information. <IMAGE>

Inventor: COCKER NEIL GRAHAM
IPC: B65G69/18
Filed: 1995-07-18
Abstract: An isolator system 10 comprises an isolator 11 moveably mounted on a support 12 and an impervious bag 16 open at one end and sealingly attachable to the isolator 11. A drum (90, Fig 9) containing a substance to be dispensed may be sealingly attached to the isolator by moving the isolator to the drum. The lid (110, Fig 11) of the drum (90) may be removed from the drum once the lidded end of the drum is within the isolator 11. The isolator is able to rotate about the axis of its support which causes inversion of the isolator and the drum now contained within the isolator. Substances contained within the drum may be dispensed into a second container, after sealing to a second end of the isolator, such as an IBC whilst contained within the enclosure thus protecting an operator from contamination from the substance. Preferably the isolator has pairs of gloves 13, 14 for manipulation. Preferably the isolator contains a valve and a feed tube. A weighing platform may be provided. In a further embodiment, the isolator is manually inverted and comprises a disposable version using a flexible tube which can be tied off and severed after transfering the contents.

Patent GB-2316265-A (GB)
Title: Communication method
Inventor: BOWATER RONALD JOHN
IPC: H04M3/42
Filed: 1996-08-09
Abstract: The present invention relates to establishing a communication channel between two communication systems having computer telephony integration (CTI). Many CTI systems are configured into incoming and outgoing lines according to the anticipated demands. Consequently, if sufficient outgoing or incoming capacity is unavailable at a given time to support a communication channel of required characteristics, the users of such a system must conventionally wait until sufficient capacity becomes available. However, the present invention determines who the intended addressee is and can instruct the CTI system associated with that addressee to instigate the establishment of a communication channel to the user who originally desired the connection. The instructions can be sent to the intended addressee using for example, another communication network, such as the Internet or other data communications network. This arrangement also allows the call to be placed in the reverse direction, where this is favourable for tariff reasons.
