Patent CA-2254495-A1 (CA)
Inventor: YOUNG JEFFREY E
IPC: G06F17/30
Filed: 1998-11-25
Abstract: A method and an apparatus that keeps track of locations in an electronic file that is represented as a hierarchical data structure, generate a point dictionary to store points that point to locations, and generate point identifiers to access the points in the point dictionary. Point identifiers are stored by ancillary routines and with components in the electronic file's data structure.  The points in the dictionary change as locations in the electronic file change, but the point identifiers do not change.  The point identifiers stored with the components in the electronic file's data structure enable the method and the apparatus to retrieve other points in the same component without conducting a search through the point dictionary.

Title: Using centrifugal pumps in the foam process of producing non-woven webs
Inventor: KOSO ARTO
IPC: D21F11/00
Filed: 1997-12-18
Abstract: A non-woven web of fibrous material is produced using a moving foraminous element in the practice of the foam process. A first foam slurry of air water, fibers and a surfactant is generated and centrifugally pumped into contact with the moving foraminous element. Substantially fiber-free foam is withdrawn from the foraminous element while forming a non-woven web of fibrous material on the foraminous element, and at least a part of the substantially fiber-free foam is used in the generation of the first foam slurry. Recycling is also typically practiced using a centrifugal pump, and the centrifugal pumps are preferably degassing pumps which remove some of the gas from the foam. By practicing the invention it is possible to produce fibrous webs using the foam process that are more than two meters wide, and at a forming speed of more than about 100 m/min (e.g. about 200-500 m/min).
