Abstract: FIELD: computing; counting. 
     SUBSTANCE: invention relates to information retrieval technology and, in particular, to a method and apparatus for hierarchical filtering of documents. Method for hierarchical document filtering comprises selecting multiple documents from a to-be-filtered document set of a current hierarchical document filtering layer according to a preset sampling strategy, and forming a first document list. Quality value of each document in the first document list is calculated. Documents in the first document list are reordered according to the quality value of each document to obtain a second document list. To-be-filtered document set of the current hierarchical document filtering layer is filtered according to the degree of consistency between the first document list and the second document list. In accordance with the invention, the to-be-filtered document set of the current document filtering layer is filtered so that the number of documents to be processed on the lower document filtering layer is considerably reduced. 
     EFFECT: technical result is shorter response time during search and lower computation costs.

Title: Non-reusable syringe
Inventor: WALLACE BRUCE INGRAM
IPC: A61G12/00
Filed: 2002-03-14
Abstract: A single use syringe (10) has an outer cylinder (11) and an inner cylinder (12) slidable within the outer cylinder. The two cylinders are initially latched together to prevent relative movement therebetween whereby the syringe is in a useable condition. A needle (16) is in fluid communication with the inner cylinder and projects initially from a first end of the outer cylinder. A plunger (21) in the inner cylinder is connected to a plunger actuating rod (22) which extends out the other end of the outer cylinder. On first depression of the plunger actuating rod a limit catch (23) prevents full depression thereof but allows sufficient depression to draw fluid into the inner cylinder. On the second depression the fluid is ejected and the plunger actuating rod and plunger are allowed full travel whereby latching between the two cylinders is disengaged. It is not possible to re-latch the cylinders together in the useable condition and therefore further use of the syringe is not possible. The needle retracts into the outer cylinder after said first use and is locked therein.
