Method and systems for real-time active refinement of search results

A computer utility for any kind of search engine or data that provides a graphical user interface for displaying search results and live refinement of the results, by automatic changing and/or offer to change the results list in real time, according to the user's demonstrated navigational interests.
The graphical user interface includes resizable windows, configured to display the contents of the links (“keyhole windows”) The search results list may be dynamically altered by real time re-searching according to the reaction of and browsing movements of the user examining the search results. In the keyhole windows users may independently browse through and view content contained therein including links.
This invention detects user intention based upon its viewing and browsing of linked websites inside the keyhole windows. Thus, the user can more easily browse through the most relevant websites for him.
This invention may also support viewing and browsing through any kind of links content which may be found in other software programs for example, e-mails, games, advertising, web search results, data bases, Internet Protocol Television (IPTV) or index lists giving real-time re-searching of any kind of search results or index lists thereby making the user's search more efficient and time saving.
In the case of advertising, the user will be presented with selected advertising more suitable to his needs and desires and the advertiser will catch an audience with an initial sympathy towards the product being advertised.

Fill type stirring friction plug repair welding method and welding tool thereof

The invention discloses a fill type stirring friction plug repair welding method and a welding tool thereof, and relates to a stirring friction plug repair welding method and a welding tool thereof. The invention adopts fusion welding or friction plug welding for repair welding and causes the welding joints to reduce strength and have poor mechanical performance. The method comprises the followingsteps: (1) the material of a stirring pin is same as that of the part which repairs welding; (2) a conical preset hole is opened; (3) the size of the stirring pin is determined; (4) positioning is carried out; and (5) welding of the stirring friction plug is repaired. The welding tool is characterized in that the side wall of a clamping hole of a lower cylinder is provided with a thread through hole; a stirring body consists of the stirring pin and a stirring pin seat which are combined into a whole from top to bottom; the outer surface of the stirring pin seat is provided with a stirring pinclamping surface; the stirring pin is a cone; the stirring body is arranged in the clamping hole on the lower cylinder; the stirring pin clamping surface aligns to the thread through hole; and the stirring pin is exposed at the outside of the lower end surface of the lower cylinder. The invention is used for repair welding of the weld defects of stirring friction welding and keyholes.

Assembled embedded type prefabricated hollow underground continuous wall and construction method thereof

The invention relates to an assembled embedded type prefabricated hollow underground continuous wall. The assembled embedded type prefabricated hollow underground continuous wall is formed by splicing a plurality of wall body units; each wall body unit comprises a wall body unit body, an upper connecting assembly and a lower connecting assembly; the wall body unit body is a hollow block body; the left side face of the wall body unit body is provided with a tenon; the transverse end surface of the tenon is a rectangle provided with an externally convex side wall, and the right side face of the tenon is a groove; the upper connecting assembly is formed by a right side opening groove body which is the same as the transverse end surface of the wall body unit body, a base plate and two L-type connecting blocks; the opening groove body is encircled by a connecting steel plate with a keyhole; an opening of the opening groove body is in inserting connection with the two L-type connecting blocks; the height of each L-type connecting block is half that of the connecting steel plate; the base plate is arranged at the top surface of the connecting steel plate, and is projected out of the outer edge of the connecting steel plate; wall body main ribs are welded on the base plate; the structures and shapes of the upper connecting assembly and the lower connecting assembly are completely the same; and the up-and-down splicing of the wall body unit is realized through bolts after the upper connecting assembly and the lower connecting assembly are in inserting connection. The assembled embedded type prefabricated hollow underground continuous wall has the advantages of shortening the construction period, improving the construction quality, reducing the probability of construction accidents, and the like.
