Title: Gasoline i.c. engine with vapour fuelling and charge stratification
Inventor: MA THOMAS TSOI HEI
IPC: F02B31/08
Filed: 1997-08-09
Abstract: A gasoline spark ignition internal combustion engine is disclosed having two or more intake passages 104, 106 supplying combustion air to each engine cylinder and a flow control valve 108 regulating the air flow along one of the passages 106 to each engine cylinder. Throttling of the air flow along the passage 106 by the flow control valve 108 during part load operation of the engine results in stratification of the intake charge in the combustion chamber of the cylinder. The gases flowing along the throttled passage 106 remain in the vicinity of a spark plug 102 near the centre of the combustion chamber at the instant of spark ignition. The engine also includes a vapour extraction system for separating the gasoline fuel into a lighter vapour fraction and a heavier liquid fraction. The invention proposes introducing fuel from the vapour fraction into the intake passage 106 throttled by the flow control valve 108 to increase the concentration of the lighter fraction of the gasoline fuel in the vicinity of the spark plug 102 at the instant of spark ignition.

Title: Error-correction decoding method for digital video recorders
Inventor: NAM SEUNG-HYUN
IPC: H04N19/89
Filed: 1997-12-12
Abstract: Digital high-definition picture and high-fidelity sound data recorded in sync blocks are reproduced from a tape deck 800. On playback, an ID corrector 714 judges whether any of the block IDs are damaged (eg by random or burst error) and generates corrected IDs to replace damaged IDs. A Reed-Solomon decoder 716 carries out inner and outer decoding on the blocks to generate error position and error magnitude information relating to each of the blocks for storage in an error information register 717. A data controller 705 judges whether or not a playback stop signal is enabled. If not, error-free and corrected sync block data is transmitted to a television receiver via a set-top box 17. An enormous quantity of computation which cannot be processed by programs, is performed in real time by an optimal data flow operation process and the compressed or processed digital data is processed at a high speed. Also, a hardware configuration of the codec which conventionally includes two or three pieces of circuit board is implemented on one custom-made semiconductor chip and cuts a unit cost of the manufacturing of the codec.
Patent GB-2332832-A (GB)
Title: Path protection with flexible routing
Inventor: RUSSELL JOHN PAUL
IPC: H04J3/08
Filed: 1997-12-23
Abstract: To ensure that a communication path between nodes (104, 122, 136, 142) of a network is maintained in the face of data interruptions caused by infrastructure failures (200, 210), network intelligence (170-173) is arranged to control switching circuits that selectively engage primary (106-108, 126-128) and standby (110-112, 130-132) paths within the network. Although only a single end-to-end circuit connection typically exists at any one time, each node sends data, such as regularly transmitted SDH overhead, on both a primary and a standby circuit. Network intelligence associated with interconnected nodes can then respond to the receipt (or not, as the case may be) of incident SDH overhead by selectively switching portions of intervening primary or standby paths to maintain at an operational connection. Typically, the network is realised by an interconnected combination of an SDH ring (102) and at least one arc or dual homed-spur (120), while the end-to-end connection is typically realised via a series of nodes that are located intermediate between subscriber terminals. The network may be wireline or optical fibre.

Title: Application head for adhesives
Inventor: DROZKOWSKI EDMUND
IPC: B05B7/08
Filed: 1998-04-06
Abstract: A device for applying liquid adhesives, especially hot melt adhesives, to lengths of material, is designed to apply the adhesive intermittently at high frequency. As best shown in figs 5a,b,c the device has a control element 11 with a channel 24 passing there through for the passage of adhesive. Housed within the control element and intercepting the passage is a control valve 26 which is rotatable and is shaped so that in one complete revolution it will open and close off the passage 24 at least once. Thus the valve can be rotated at high speed resulting in high speed intermittent delivery of the adhesive through nozzle 30. Preferably the valve 26 is cylindrical in shape but it can also be a rotating plate with a suitable aperture.

Title: Capability negotiation in a telecommunications network
Inventor: GRAF LESLIE
IPC: H04L12/70
Filed: 1999-05-17
Abstract: Node A represents an originating signalling point to which a calling party is connected whilst node C represents a terminating signalling point to which a called party is connected. Each of the signalling points comprises a call control level and a bearer control level. The bearer control level, comprising a bearer network such as an Internet Protocol (IP) network or an ATM network. When a calling party initiates a call, the originating signalling point generates a list of possible options relating to the capabilities of the originating signalling point which must be negotiated with the terminating signalling point node C. Node A sends a message to node C specifying the list of options in order of preference. Node C selects the preferred option and signals its choice to node A. Capabilities which may be negotiated in this way include the choice of a suitable speech codec for the call or security capabilities such as voice ciphering or data encryption.

Title: Combined passive and active focussing system
Inventor: HIGASHINO FUMINOBU
IPC: G02B7/32
Filed: 1999-09-28
Abstract: A line of charge coupled device (CCD) elements are operated as two passive sensors (PSA, PSB) and one active sensor (combined with light source 40.) An image is formed on the sensors by the optical system 20. A control circuit 50 initially operates the passive sensor, selecting a measurement region on both sensors which is then shifted pixel by pixel to establish the difference between their outputs and uses this information to focus the camera. The device may switch to the active sensor if the passive measurement is inadequate. An infra-red cut off filter over the whole CCD array 33 and a visible cut off filter 34 over the active sensor may be used. The apparatus may be used with a variety of digital, video or silver film cameras.

Filed: 1992-11-26
Abstract: In the case of this command and signalling apparatus, a cup (2) having a collar which supports an annular shutter (3) on the operator side passes through an opening in a covering panel (1). Arranged displaceably in the cup (2) is an acknowledgment element (4) having a hollow-cylindrical head part, a first guide, a second guide and a plunger. A sleeve (13) can be pushed forward over a thread (12) winding on the circumference of a switch carrier (11) until said sleeve (13) together with the collar of the cup (2) forms a firm seat with the covering panel (1). Provided at the rearward end of the switch carrier (11) are board holders (14) which carry a second printed-circuit board (15) on which a microswitch (16) is arranged which is operated by the plunger. Arranged in the head part of the acknowledgment element (4) is an annular optical conductor (18) which is connected to a first printed-circuit board (17) and conducts the light from light-emitting semiconductors, which are integrated on the first printed-circuit board (17), to the underside of a glass (19) which closes the command and signalling apparatus on the front side. The light-emitting semiconductors are controlled by means of photosemiconductors as a function of the ambient lighting, so that the visible light ring on the glass (19) illuminates more brightly as the ambient lighting becomes brighter. A flexible multi-core conductor (21) connects the first printed-circuit board (17) to the second printed-circuit board (15), via soldering points (22) and plug-in contacts (23). <IMAGE>
