Abstract: A method and system for ranking search results is disclosed. Search sessions are tracked to determined accessed search results. For each accessed search result occurring across the plurality of search sessions, the accessed search result is associated with each search query having been executed within a given search session, prior to the user accessing the accessed search result. A preselection is made among the query elements forming each search query, for indexing the selected query elements. For each pairing of a query element from the preselection and an associated accessed search result, a result score is calculated. A ranking model is then generated. The ranking model contains the result score in association with the corresponding pairing, for ranking subsequent search results from subsequent search queries according to the result scores.

Abstract: A personalized search engine system and corresponding method which is used by an identified user for retrieving documents on a corporate network or intranet. The identified user being related to a unique personalization identifier (UPID) and to a list of group personalization identifiers (GPIDs). The system comprises a search engine interface for obtaining a query from the identified user; a search engine for finding documents matching the query; and a ranking engine for ranking the documents matching the query in order of relevancy, where the ranking is partly based on a previously calculated document rating for the UPID of the identified user, where the ranking is further based on a previously calculated document ratings for each of the GPIDs of the identified user.

Abstract: A high pressure pump (14) supplies cleaning fluid from a reservoir (12) to spray nozzles (20) inside a washing chamber (10). The spray nozzles (20) spray the cleaning fluid over a load to be cleaned. Used cleaning fluid is collected in a sump (30). A sump pump (32) drains the sump. The combination of the high pressure pump and sump pump provides more efficient cleaning of the load and eliminates the requirement for a deep sump beneath the washer. A vertical traveler (22), having a pair of counterbalanced spray arms (24), raises and lowers the spray nozzles counter cyclically; a detergent injection system (50) accurately meters a correct amount of detergent is added to the cleaning fluid; and a filtration device (34) filters suspended material from the used cleaning fluid and uses a portion of the cleaning fluid to clean itself.

Abstract: Retractable doors 22 to a washing chamber 20 of a washer 10 open automatically to allow a load to be processed to be wheeled into the chamber. The doors are fitted with blowout panels 42, 44. In an emergency, a worker trapped in the washing chamber can escape by pushing the blowout panels outward. A tilting floor assembly 70 includes a floor 76 supported on a frame 74 and a lifting mechanism 90 for selectively raising and lowering a side of the frame to tilt the floor. The floor is tilted automatically during a cleaning cycle to allow cleaning fluids to drain from the load, then leveled before opening of the doors for ease of removal of the load.

Abstract: An operating system (20) for a washer (1) is mounted on a moveable trolley (52). The trolley carries all of the failure prone elements such as pumps (24, 28, 40) solenoid valves 80, electrical heaters (48), an electrical control circuit (50) and the like. Quick-release couplings (58, 59,60 62), between the operating system and plumbing associated with a washing chamber (10), allow the operating system to be quickly disconnected from and reconnected with the chamber. The trolley is then wheeled a distance away from the chamber, providing ready access to all the operating equipment for maintenance and repair.
