Patent GB-2223864-A (GB)
Title: Air-fuel ratio control system for automobile engine
Inventor: ABE KUNIHIRO
IPC: F02D41/14
Filed: 1989-10-03
Abstract: In the air-fuel ratio control system, a basic fuel injection quantity Tp is calculated at S101 from measures of engine speed SE and intake air quantity QA. Various correction coefficients CI, KS and TS are then set and a feedback coefficient  alpha  is calculated S109-S111 in dependence on the output of an O2 sensor when the engine is operating in a feedback region. A learning coefficient KLC is then determined at S113, and at S114 it is determined whether any discrepancies between a reference a/f ratio and a measured a/f ratio are likely to be caused by deterioration of the air quantity sensor or the fuel injection system. The learning coefficient KLC is used to correct the basic injection quantity Tp at S115 or the actual corrected fuel quantity Ti at S116 depending on the result at S114. The determination at S114 may be on the basis of a comparison between intake air quantity QA and a set threshold QF. …<IMAGE>…

Title: Locating electrical faults in optical transmission system
Inventor: OSWALD THOMAS
IPC: H04B10/00
Filed: 1990-03-22
Abstract: A method of locating an intermittent electrical fault in an optical undersea transmission system, comprises measuring the time difference between two signals emanating from the fault along two different routes of the system. In one embodiment one of the signals is a voltage transient and the other signal is an optical error signal created in a repeater adjacent the fault as a result of surge protection in the repeater responding to the electrical fault, and in another embodiment both signals are optical signals, once again emanating from adjacent repeaters and caused by the effect of the electrical fault on the adjacent repeaters. It is envisaged that such a transmission system could be permanently provided with apparatus to detect such a fault in which synchronised counters are permanently running and frequently re-set and which stop in response to error signals being received from a fault when it occurs. <IMAGE>

Title: Deployment and recovery of pre-packed screens
Inventor: SNOW NIGEL
IPC: E21B23/00
Filed: 1990-05-04
Abstract: A bottom hole assembly (BHA) comprises pro-packed screen 1, washpipe 2 and stinger section 3. The screen has an outer fluid permeable wall 4, an inner permeable wall 5 and an annular layer of pre-packed particulate material 6 therebetween. Fluid can flow radially inwardly through the screen into the annual space 7 between the screen inner wall and the washpipe outer wall. Washpipe sections are coupled by a subsection of pipe 8. The ends of the coupling are joined to respective ends of sections of washpipe by conventional means. Screen sections are joined together by a stinger 3. Conventional joining means may be used. The stinger has a portion of its length necked down, and this portion has a polished sealing surface 9 which can provide a contact seal to a pair of appropriately sized pipe rams (not shown). Internally of the stinger, at the same level as the external sealing surface, there is an internal polished sealing surface. An annular seal 10 carried on a sub-unit 8 forms a contact seal on this internal sealing surface. Thus, fluid from the annular space 7 cannot pass by the seal 10. A method for deployment of a BHA as described above is disclosed. The BHA may be deployed in an oil/gas well under pressure. <IMAGE>

Title: Method of controlling handoff in cellular mobile radio communications systems
Inventor: KANAI TOSHIHITO
IPC: H04W36/30
Filed: 1991-01-31
Abstract: The speed of a mobile 10, in communication with a base 14i is determined by monitoring Rayleigh fading of the signal strength received from base 14 in order to adjust a threshold level so that the threshold increases with decrease in mobile speed (Fig 3). If the median of the signal strength received at mobile 10 from another base 16 or 18 exceeds that received from base 14 by more than the threshold level, a handoff request is issued. Rayleigh fading is monitored by detecting the rate at which the instantaneous signal strength received at mobile 10 from base 14 crosses the short-term median level of that signal, that rate being dependent on the maximum doppler frequency which increases with mobile speed. The median measuring time period may increase with decrease in the maximum doppler frequency (Fig 4). In a second embodiment, (Fig 2), a base (52), in communication with a mobile (58), similarly adjusts a threshold level which is compared to the difference between the medians of the signals received from mobile (58) at bases (52), (54) to determine if a handoff request should be issued. <IMAGE>
