Title: Water-disintegratable fibrous sheet containing fibers having different fiber lengths and process for producing the same
Inventor: TAKEUCHI NAOHITO
IPC: D21H17/27
Filed: 1998-08-31
Granted: 2005-07-26
Abstract: A water-disintegratable fibrous sheet comprising a web of fibers comprising pulp of hardwood and pulp of conifer, pulp of conifer having a fiber length longer than that of the pulp of hardwood, and a water-insoluble or water-swellable binder being contained in the web to bind the fibers, is disclosed. The fibrous sheet is excellent in water-disintegratability and has sufficient strength for withstanding practical use. Furthermore, since excellent water-disintegratability and strength can be obtained without using a water-soluble binder, a production process of the fibrous sheet can be made simple.

Title: In-line seed treating unit for air seeders
Inventor: SCRIBER TED M
IPC: A01C7/08
Filed: 1999-05-20
Granted: 2009-05-12
Abstract: An in-line seed treating unit is provided for an air seeding implement to coat seeds carried by a flow of air through a product distribution line before being planted into the ground. The in-line seed treating unit includes a cylindrical housing having input and outlet ends located at opposing axial ends of the cylindrical housing to provide a generally linear overall flow path for the seed entrained air flow through the product distribution line. A baffle formed as a spiral flighting with an open center portion is disposed within the cylindrical housing to induce the air flow and entrained seeds in a spiral flow path along the housing axis and, thereby pushing the entrained seeds outwardly toward the inner wall of the housing. The seed treatment material is injected through an injection port located at a distance less than one flighting pitch of the baffle so that the seed treatment material is dispersed within the air flow to coat the entrained seeds. Preferably, the in-line seed treating unit is formed as a modular component that can be inserted into any selected product distribution line on the air seeding implement.

These outer face surfaces of the elastomer support plates are adapted to be disposed is intimate face-to-face relation with internal wall surfaces of ram seal receptacles that are provided within BOP ram elements. Each of the rectangular elastomer support plates defines a pair of spaced retainer receptacles which receive a respective retainer element of a BOP ram to secure the ram seal unite in retained relation within one of the ram seal receptacles of a BOP ram element. When so supported, the elastomer sealing material located between the generally rectangular elastomer support plates and encapsulating the central web structure of each integral ram seal block, will be pry for sealing contact with its opposed counterpart of the opposed BOP ram element and with the wireline that is present within the body of the BOP unit.

Title: Extension of link aggregation protols over the network
Inventor: MARK BARRY DING KEN
IPC: H04L12/56
Filed: 2001-06-15
Granted: 2004-09-07
Abstract: An extension of a Link Aggregation Protocol (LAP) over the network allows current Ethernet point-to-point LAPs to operate across a Metropolitan Area Network (MAN). A maximum disjoint path algorithm allows selection of a plurality of alternative end-to-end physical routes between two data terminals. These physical routes share a minimum number of nodes and physical links. End-to-end logical links are then formed by a plurality of successive physical links between nodes containing protocol compatible devices, the physical links being selected based on their physical characteristics such as bandwidth and delay. Multiple logical links can be provisioned, without dedicating, between any two data terminals over the network. The logical links provide the virtual point-to- point links that the edge LAP devices require. The extension of LAP/s over the network provides increased availability because a network failure can now be propagated to the edge of the network to allow the edge LAP devices to quickly react to the failure.
