Title: Fuel-injection pumps for internal-combustion engines
Inventor: RAPP KARL
IPC: F02M59/26
Filed: 1995-11-29
Abstract: A fuel-injection pump for internal-combustion engines has a cylinder (3) with a spill bore (8) and a piston (5) with separate regions which cooperate with the bore (8) to control the fuel-injection quantities during cold and hot engine operation. During cold operation a control edge (16) and an oblique control edge (22) of a recess (20, 21) register with the bore (8) to control the effective stroke, fuel spilling from the working chamber (7) via a longitudinal groove (12) and the recess (20, 21) to end injection. For hot operation the piston is rotated to a region having axially displaced control edges (17, 23). In the transition between these regions the bore (8) always overlaps the control edges (17, 23) and a narrow extension (25) of the longitudinal groove (12) communicates with a further spill port (26). Thus zero injection results without the piston having to move through the cold running region to the position in which the longitudinal groove (12) is in permanent communication with the bore (8). <IMAGE>

Title: Optical frequency channel assignment plan and filtering technique to support it
Inventor: DAVIES FIONA
IPC: H04B10/18
Filed: 1997-07-18
Abstract: In order to reduce four wave mixing between wavelength channels in a bidirectional optical fibre system the channels are assigned as follows: Each channel is mutually exclusive with respect to wavelength. At least one of the two communication directions has at least one pair of channels having adjacent wavelengths. Each direction also has at least one other channel which is not adjacent to this pair. To support this interleaving of optical channels and to provide sufficient isolation between them an optical filtering circuit is used. This circuit comprises two circulators 60 and 62, optical fibres 16 and 18, amplifiers 20 and 22, transmission filters 64 and 66 and mirrors 68 and 70. Broadband signals, containing a plurality of adjacent channels, entering this circuit are routed via one circulator, 60 or 62, through one of the filters, 64 or 66, to isolate, on an individual basis, at least one desired channel. This filtered signal, is then reflected back into the filter 64 or 66, by the mirror 68 or 70, such that the at least one desired channel is subjected to a second filtering process that further improves its isolation. Following this second filtering process the at least one desired channel exits the circuit via the other circulator 62 or 60. Other optical circuits, utilising four circulators are also disclosed.

Title: system for eliminating time-expired messages from a message queue in a data processing system
Inventor: HICKSON ANDREW
IPC: G06F9/46
Filed: 1997-10-04
Abstract: A data processing apparatus runs a messaging and queuing software package whereby a newly-received message is added to a queue (11, Figure1). Associated data including 96-bit message time expiry data are stored in a high storage-capacity long-term storage hard disk drive device (14). An abbreviated version (24 bits) of the message time expiry data is stored in a low storage capacity high-speed cache memory device (12). When retrieval of a specific message from the queue is requested, the version stored in cache of the expiry data for each, or for alternate ones, of the messages stored in the queue is compared 32 with the current date and time in 24-bit format. Any message of which the 24-bit expiry data are of a value equal to, or less than, the current date and time, is deleted 33 from the message queue. Then the specific message requested is retrieved 34 from the message queue, and a full one-millisecond (96-bit) expiry data check is made 35, to determine whether this message has become time-expired in the last four minutes. In this way, long-expired messages (ie those that have been expired by at least four minutes) are discarded more efficiently than in the prior art.

Title: Infra-red communication terminal which decreases current used when remaining battery capacity is low
Inventor: MOTOHASHI TERUYUKI
IPC: H04W52/02
Filed: 1999-03-30
Abstract: In a mobile data terminal having an infrared communication capability, a battery capacity detection 4 determines whether or not the remaining capacity of a battery 5 is smaller than a preselected threshold value. If the remaining capacity is greater than the threshold value, a data processing 1 causes a drive current control 3 to feed a first preselected drive current to a light emitting device 21 included in an infrared communication function 2. If the remaining capacity is smaller than the threshold value, the data processing 1 causes the drive current control 3 to feed a second preselected drive current smaller than the first drive current to the light emitting device 21. As a result, when the remaining battery capacity is small, a distance which infrared rays reach is reduced in order to maintain the infrared communication capability. A decrease in the above distance is reported to the user of the data terminal via an output 8 for thereby insuring convenient use.
