Title: "Fencing"
Inventor: DUNKLEY DOUGLAS GORDON
IPC: E04H17/00
Filed: 1991-09-18
Abstract: A fence has a post 8, interconnected with transverse members e.g. 9, which are locked into an undercut channel on post 8, e.g. by means of a pin 14, and bushes 13. Packing members 32, which can be cut to any length, enable any transverse members to be positioned where required. The transverse members may have convex faces, or be substantially I-shaped and, together with the posts, may be of plastics material. The transverse members can have their ends cut to any angle to suit any slope. Adjacent transverse members are locked together by clips 12, which allow the wind to pass between transverse members, while allowing complete privacy when transverse members are fitted onto one another.   <IMAGE>

Title: Controlling fuel vapour purging
Inventor: ABE KIYOMI
IPC: F02D41/00
Filed: 1993-06-30
Abstract: In an ic engine having a system for purging fuel vapours from the fuel tank to the engine intake, air fuel ratio correction learning values are updated each time the engine or ignition is switched off. The deviation, resulting from the canister purge, of the air fuel ratio learning value at each address of a map is calculated S501, the average of the deviations is subtracted from the air fuel ratio correction learning value for each address S503 and the air fuel ratio correction value is updated using the result of the subtraction for each address. In this way the deviation of the air fuel ratio due to canister purging can be calculated and driveability, starting and emissions can be improved by updating the air-fuel ratio learning values excluding deviations caused by the canister purge. Also disclosed (figure 1) is a system whereby purging of the fuel vapour in a canister is controlled by determining a correction amount to the purge control duty correction. The purge control duty correction is determined by assuming the canister loading ratio from a look up table based on the change rate of an air-fuel ratio correction coefficient  alpha  per unit duty. As a result, canister purging is controlled in accordance with the canister loading amount so that overloading of the canister can be prevented even under high evaporation conditions such as high temperature or high altitude. <IMAGE>
